Every year more than ~0.6 MT of oil is discharged in ocean waters. Consequently, considerable amount of oil contaminants is found in and near water surface, which have a great impact on the world ocean ecology. This chapter describes ways to clean oil and oil containing contaminants at and near the surface of water and in events, when there is an underwater leak caused by natural fractures, leaks or mining accidents. An effective sorbent consisting of expanded graphite (EG) is proposed, which can be used as good sorbent, not only for cleaning oil pollution, but also as filter, since it has bulk density as low as 4 kg/m3, noting that and 1 g EG has specific surface ~80 m2, which binds ~80 g of oil or petrol. Physical and chemical properties of EG, as a sorbent, are analyzed in comparison with activated carbon. Furthermore, since drinking water supplied through corroded pipes is of poor quality, conventional filters clog quickly. Therefore, filters using EG can be used efficiently in the first stage of cleaning. Mobile equipment for producing EG onsite of accidents is described. The equipment consists of several structural units: gas supply unit, burner unit, graphite feed unit, reaction chamber, separation and output units. The reaction chamber was designed, such that a standing vortex is formed, by which there is a thermal shock and additional expansion of unopened graphite particles. Automation and simulation of the combustion process in the chamber has shown to improve the quality of EG, which reduces equipment dimensions and enhance efficiency.

The objective of this chapter is to evaluate assessment methodology of one of the most basic parameters of water, termed as water quality, also defined as Water Quality Index, in view of recent technological advancements. The chapter focusses on drinking water only, however various other applications, such as in agriculture, transportation and industries, viz. pharmaceuticals, power generation, hydrocarbon, catalysis, chemical processing, mining, hydrometallurgy, and semiconductor processing can benefit from a similar approach. The quality of water varies from region to region and is highly dependent on regional water stressors and available water purification methods. Despite of recent advances in water filtration mechanisms, new and emerging contaminants and local water stressors, are not filtered effectively. Conventional methods use commercial-off the shelf systems and broad-spectrum analytical instruments with interpretive algorithms to sense/detect and characterize contaminants. Since contaminants differ greatly in chemical structure and chromatographic/spectroscopic behavior, it is extremely difficult, if not impossible, to apply generic methods to interrogate most contaminants in real-time. Several regulations have been implemented to control the use of several chemicals that are toxic to human health. We provide an assessment strategy and Internet of Things based sensor platform, combined with geolocation capability, as Smart and Connected Systems approach for interconnectivity. We introduce a Universal Water Quality index, which is based on an algorithmic determination based on a series of contaminants that may be present in quantities significantly less than the acceptable quantities. The methodology presented here is likely to provide Universal Water Quality Index, in compliance with policy frameworks for chemicals that remain in processed water after a series of efficient contamination mitigation strategies, leading to enhanced water quality for better quality of life and better living standards. We provide an overview of new materials and technologies with unforeseen capabilities to sense/detect multiple exposome in label-free and highly multiplexed format, with ppb/ppt sensitivity, high selectivity and specificity, all with streaming data analytics in real-time. Additionally, there are multiple approaches to analyze solutions for regional sustainable development and the one most frequently employed approach is factor analysis for the regional industrial sector as well as approaches based on the monitoring of core determinants of economic growth rates for sustainable development. These approaches are influenced by numerous parameters, which need to be analyzed, systematized, and processed before they are used to create plans of development. Factor analysis approach, consistent with millennium development goals of the United Nations Development Program, was conducted and methodology and conclusion are described.

Cryogels are polymeric matrices with 3D architecture fabricated by cryotropic gelation at subzero temperatures via co-polymerization of monomers or crosslinking of linear polymers. The main characteristic feature of these materials that distinguishes them from other gels is their continuous and highly porous structure resulting from cryopolymerization that occurs in a two-phase environment. Highly porous polymeric cryogels can be produced in various shapes and sizes. There are many application areas of cryogels due to their individual properties. The applications of supermacroporous cryogels in the biomedical and biotechnological fields have been well reported in the literature. However, studies on the use of these unique gels in wastewater treatment as a solid adsorbent have started to attract attention in the last few years. The cryogels are suitable adsorbents for the removal of non-degradable organic and synthetic toxic compounds in wastewater. In addition, these cryogel matrices have superior properties including high surface area, high porosity, spongy structure, and physical stability during swelling conditions compared to other gel materials available. This chapter highlights the details of cryotropic gelation, process parameters effective on characteristics of cryogels and utilization areas of these materials specifically in water purification applications.

Scientific and public concerns due to presence of microplastic debris in the marine and freshwater environment is fueling concerns of its impact on aquatic ecosystems and public health. Major sources of water-polluting microplastics are polyethylene and polypropylene, as they aggregate near the waterair interphase. Such neustonic hydrophobic cells attract spores of bacteria causing adverse impact on the environmental, health and food supply chain. The objectives of this review investigation were to (a): evaluate the concentration of microplastics with the sizes less 100 μm floating near the waterair interphase; (b): develop a phenomenological model to study fate and transport of microplastics; (c): analyze microbial coatings, and (d): assess potential impacts of biofilm-coated neustonic microplastics on environment. A thorough review of microplastic pollution in marine environment was conducted in terms of its size distribution, toxicity and toxicokinetic pathways. Since biofilms coated microplastics float near the surface, hydrophobic cells of bacteria typically concentrate within a few micrometers layer of water-air interphase. To develop a phenomenological model of neustonic floating biofilm-coated microplastics, samples with the size of less than 100 μm were collected from within a few millimeters near the water-air interphase and were subsequently concentrated using microfiltration of water samples for analysis. Results of the optical scan of hexadecane and bacterial cells formed on vertically submerged microscope slides near water-air interphase are presented. Additionally, microplastics near a thin layer of water-air interphase were investigated using scanning electron microscopy, fluorescent microscopy, flow cytometry, and particle analyzers. Since, hydrophobic and putative pathogenic bacteria are attached to water surface, which dominate near water-air interphase, biofilm-coated microplastics are more attractive for consumption by aquatic species than pure microplastics, which significantly increases negative impacts of microplastics on aquatic ecosystems and public health through foodchain supply. We conclude that it is critical to extend this investigation to include safety in terms of aquatic ecotoxicity, security, risk assessment, life-cycle analysis, upcycling of plastics and policy recommendation on this new category of water pollutant.

The objective of this investigation is to synthesize and investigate zero-valent iron (ZVI) nanoparticles (NPs) for bioremediation applications. The ZVI-NPs were fabricated by chemical reduction using a ferrous salt solution with poly(N-vinylpyrrolidone) (PVP), used as a stabilizer. The synthesis was conducted with and without ultrasonic treatment. The ZVI NPs were fabricated and characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) analysis, and Fourier Transform Infrared Spectroscopy (FTIR). Experimental observations demonstrate that depending on synthesis conditions and coordination of stabilizers, NPs with different morphologies are formed. Colloidal solutions of the synthesized NPs were used in antimicrobial activity tests and biofilm formation assays for nine different control microorganisms: Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 15692), Enterococcus faecalis (ATCC 29122), Klebsiella pneumoniae (laboratory isolates), Proteus vulgaris (laboratory isolates), Staphylococcus aureus (ATCC 29213), Bacillus cereus (DSMZ 4312), Bacillus subtilis (ATCC 6633), and Candida albicans (ATCC 10231). All control strains did not show antibacterial effect against PVP-stabilized ZVI NPs synthesized without ultrasonic treatment. However, biofilm results show that the highest absorbance values of the micro-organisms were tested in control wells. Although B. subtilis, E. coli, and K. pneumoniae were observed during biofilm formation, B. cereus, S. aureus, and P. aeruginosa biofilm formation reduced noticeably by Fe0/PVP-US (A1) NPs. For control strains, such as E. faecalis and C. albicans, no biofilm formation was observed. For Fe0/PVP (A2) NPs, biofilm formation of B. subtilis, E. faecalis, E. coli, K. pneumoniae, P. vulgaris, and C. albicans demonstrated positive effect, and B. cereus, S. aureus, P. aeruginosa showed negative effect. A strategic utilization of nZVI-PVP nanoparticles showed a great potential for effective, efficient, and sustainable bioremediation applications.

The concentrations of some heavy metals (Fe, Zn, Mn, Cu, Mo, Pb, Cd) were measured in river waters, macrozoobenthos, and fish (Kura scrapers) from one of the most developed mining areas in Armenia, the Debed River catchment basin. In order to assess heavy metal contamination and its hydro-ecological and health effects, the macrozoobenthos quantitative and qualitative parameters, geo-accumulation index, and hazard index were determined. Microalgal extraction experiments were conducted to assess the microalgal remediation efficiency for heavy metal removal from mining wastewaters. The results showed that the rivers in many sites were polluted with different heavy metals induced by mining activities, which adversely affected macrozoobenthos growth and caused human health risks in the case of waters used for drinking purposes. However, the river fish, particularly Kura scrapers, were determined to be safe for consumption by the local people, as per the conditions of the evaluated fish ingestion rate. The results have shown that microalgal remediation, particularly with Desmodesmus abundans M3456, can be used for the efficient removal ~(62–100%) of certain emerging contaminants (Mn, Pb, Cu, Zn, Cd) from mining wastewater discharged in the Debed catchment basin.

In our ongoing investigations, we have studied a specific interaction between electromagnetic fields and matter – the so-called Electromagnetic echo effect (EMEE). It enables rapid and contactless investigations of gases, liquids and solids to be performed, since the signal generated as a result of the effect is quite sensitive to all kinds of changes occurring within the studied samples. The effect can be considered universal for all matter and provides analysis in real time. We use this phenomenon to demonstrate the practical possibility to control reactions, occurring between Chicken anemia virus (CAV) and the corresponding antibodies. This methodology can be used for simple but reliable control of similar, otherwise hard to detect, antigen-antibody reactions, in order to confirm the presence of a certain viral species. The approach offers a high level of safety, since it enables measurements to be taken remotely, thus limiting exposure to contagion. We further discuss the possibility to register the presence of SARS-nCoV-2 in an attempt to address current global pandemic.

Sustainable development of a regional and local community involves setting a strategic balance among economic, social, and environmental criteria (factors) of development. Due to their large number, physical quantity variance, and incompleteness, these factors have a limited, sometimes even conflicting and ineffectual application in producing a unified effect on development. This issue becomes resolvable through a modification of factor analysis by means of combining it with multi-criteria decision analysis (MCDA). The solutions thus obtained in the form of a ranking, with the top-ranked solution being the most favorable, constitute immense support for decision makers to use the proposed most favorable solution to formulate and implement their plan of development.

The development of membrane technology from biopolymer for water filtration has received a great deal of attention from researchers and scientists, owing to the growing awareness of environmental protection. The present investigation is aimed at producing poly(D-lactic acid) (PDLA) membranes, incorporated with nanocrystalline cellulose (NCC) and cellulose nanowhisker (CNW) at different loadings of 1 wt.% (PDNC-I, PDNW-I) and 2 wt.% (PDNC-II PDNW-II). From morphological characterization, it was evident that the nanocellulose particles induced pore formation within structure of the membrane. Furthermore, the greater surface reactivity of CNW particles facilitates in enhancing the surface wettability of membranes due to increased hydrophilicity. In addition, both thermal and mechanical properties for all nanocellulose filled membranes under investigation demonstrated significant improvement, particularly for PDNW-I-based membranes, which showed improvement in both aspects. The membrane of PDNW-I presented water permeability of 41.92 L/m2h, when applied under a pressure range of 0.1–0.5 MPa. The investigation clearly demonstrates that CNWs-filled PDLA membranes fabricated for this investigation have a very high potential to be utilized for water filtration purpose in the future.

Water contamination by petroleum and its byproducts presents a major challenge worldwide. It is critical that sustainable treatment methods be employed for the removal of such contaminants from polluted water. For this investigation, magnetic nano silica (M-NS) was synthesized using agricultural waste from barley husk using a two-step process that is environmentally friendly and uses green chemistry synthesis. The barley husk waste was used as a precursor for the synthesis of nano-silica following a low energy and sustainable method of acid reflux and heat treatment. Nano-silica was then used for the synthesis of M-NS, with the addition of a magnetic solution of Fe3O4 nanoparticles. The magnetic nano-silica particles were characterized using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), Zeta potential analysis (ZETA) and X-Ray Diffraction (XRD). Magnetic nano-silica particles were observed to have an average diameter of 162 nm and appeared to be hydrophobic, with a large surface area of ~120 m2/gm. Due to these characteristics, magnetic nano-silica was used as an adsorbent for the removal of petrol contaminants from water. The experimental procedure showed that only 0.6 gm. of M-NS was used on 40 mg/L concentration of petroleum and the experiments recorded a high uptake efficiency of 85%. The sorption was shown to be an effective process since a high amount of petroleum was removed. The study further demonstrates that as the amount of sorbent is increased, the sorption capacity also increases until an equilibrium is reached. The results of this study establish that synthesis of M-NS, using environmentally sustainable processes, has the required characteristics to serve as sorbent for petroleum and its byproducts from contaminated water, thus enhancing environmental sustainability.

In the new and transformative era, our surrounding environments are increasingly connected through exponential growth of cyber-physical systems (CPS) and interactive intelligent technologies. One such example includes technological innovations in Unmanned Aerial Surveillance Platforms, also known as drones, for applications such as surveillance, real-time monitoring, emergency augmentation for actionable response, security and enabler of connected communities to bring about new levels of opportunity and growth, safety and security, health and wellness, thus improving the overall quality of life. Based on our previous experiences, we present a modality of smart and connected sensors platforms that have a great potential to provide enhanced situational awareness for safety and security. The objective of this investigation is to develop a mobile Unmanned Aerial Surveillance Platform (UASP) capable of monitoring in real-time, capturing, synthesizing and analyzing the information and allowing communication with ground-based systems for actionable response. Several commercial off the shelf (COTS) instruments such as hyperspectral imagers, Light Detection and Ranging (LIDAR), Laser-induced Breakdown Spectroscopy (LIBS) and Biometrics Facial Recognitions systems are discussed along with some innovative platforms that are still in experimental stages and can potentially serve as payload to the unmanned aerial vehicle (UAV) sensor platforms. The new system under development has an airborne component to capture relevant information from a Domain of Interest (DoI). This paper summarizes the capabilities of UASP along with several potential applications and potential risk scenarios of such smart and connected by internet of everything (IOET) systems.

The primary task of protective clothing is to maximize the user’s survival, sustainability and effectiveness against cold, heat, fire, ballistic, biological, radiological, nuclear and chemical agents. The protective textiles made of many different fabric materials have been widely used to provide effective protection for various specific applications. With the recent and ongoing advancements in nanotechnology, it is desirable that protective textiles have multifunctional properties. Thus, the newly developed composite materials gained various features such as flame retardancy, UV protection, pollutant capturing, antibacterial property, decontamination, detoxification and self-cleaning ability as well as providing wearing comfort. These properties can be achieved by incorporating functional agents (specific functional ligands or molecules, nanoparticles and drugs) into fabricated materials. Therefore, a new generation of protective fabrics has been produced in recent years. Electrospun textile materials are suitable for use as new protective clothing due to their easy production method, breathable, lightweight, comfortable and functionalizable properties. The electrospun membranes can be fabricated with diverse morphologies (core-shell, side-by-side, multilayer, hollow interior and with high porosity) by regulating the operating conditions and modifying the needle device. Electrospun nanofibers can be used in various application areas including filtration, sensing, wastewater treatment, biomedicine and protective textiles due to their extraordinary physicochemical features at nano level. This chapter aims to review recent advances of the electrospinning technique and the use of multi-functional electrospun materials for protection against chemical and biological agents.

The photoelectronic processes in p+ -n-p+ structures are studied for this investigation. The regularities of the width change of the adjacent barriers subject to the external voltage and the concentration of impurities in the base are revealed. The relations between these changes and the selective photo-sensitivity of the structure are shown. The possibilities of the effective registration of individual wavelengths from the integral radiation flux and the possibilities of the determination of the intensity and the length of these waves are analyzed. The necessity to develop a structure which will be used for the creation of a cheap, fast-acting system of optical analysis fit for use in the field is shown. The capabilities of the spectral selective sensitivity of the investigated photodetector structures are studied via obtaining the spectra of three LEDs (blue, green and red). The problems encountered are revealed and the solutions are suggested. The comparative analysis of the selective sensitivity and of the complexity of the production technology of the investigated photodetectors and that of the existing multilayer semiconductor photodetectors with active cascade-like layers is carried out. The possibility to carry out the optical spectral analysis by the investigated structures without the use of high-accuracy mechanical devices, light filters, prisms and diffraction gratings, and the possibility to apply the investigated photodetectors for the creation of multi-purpose spectrophotometers and monitoring systems which will be used for obtaining the information on the investigated medium and for solving the important security problems via conducting identification processes are studied.

Setting priorities in a complex defence environment requires technology assessment, data driven decision support tools, foresight, and roadmapping the future pathways. There are several procedures to deliver a balanced, yet strategic assessment. This report posits roadmapping of revolutionary scientific breakthroughs based on advanced sciences convergence (ASC) in multidisciplinary environments and data analytics platforms. Innovations lead to mapping technology roadmaps which are cautiously formulated based on extensive research, expert elicitation and networking approaches to project “future scenarios” realistically and epistemologically. Such roadmaps enable the development of transformative tools and methodologies that fill fundamental knowledge gaps. Synergy arising from converging technologies and research methodologies will leverage emerging and potentially transformative studies. A “framework by design” of emerging scientific and technological advances and trends is developed through a systematic and strategic planning process to deepen the understanding of current, future, and varying challenges and opportunities and create fully integrated solution pathways to address current and future global issues. Through a systematic introduction of ASC, the methodology exploits future-oriented analytical methodologies, including heuristics, data-mining, scientometrics, modelling and simulation, and scenario development to provide solutions and their potential for integrated, novel and unconventional manifestations.

In asymmetric and complex warfare environments, it is critical to deploy the latest technological innovations for tactical advantage over adversaries. Among others, improvements in outerwear of soldier uniform provide a significant tactical advantage. We have studied the use of loaded nanofibers, which demonstrate capabilities such as light weight, mechanical resilience, and breathability, i.e. the possibility for the evaporation of perspiration. In addition, the fibers are capable of sensing chemical/biological environment and delivering therapeutics thus providing temporary relief from injury. Furthermore, nanofibers include communication capabilities for enhanced situational awareness. This investigation outlines an ongoing research on loading electrospun nanofibers with selected materials to produce outerwear for soldiers providing tactical superiority. Fabrication and characteristics of some of such fibers are presented here along with future pathways to integrate additional capabilities.

Chemical and biological agents effects tissues and organs which cause poisoning, disease, and deterioration. Chemical or biological weapons show significant threats to humankind. Therefore, many studies have presented approaches for protection from biological and chemical agents. There are various types of defence equipments to protect a body from those agents such as developed detectors, protective clothing materials, functional decontaminants, and others. A number of studies have reported about protective clothing against chemical and biological agents, because many of them are dermally active. New protective clothing materials (comfortable, adsorptive, light-weight) combined with active detoxifying/decontaminating nanomaterials have been produced recently. Electrospinning is one of the simplest and most versatile methods to fabricate nanofibers with high surface areas. Electrospun polymeric nanofibers were used as a protective barrier on the textile fabrics. Attempts have been made to incorporate nanoparticles, nanotubes and antimicrobials into electrospun fibers to enhance their functionality. In this contribution, a selection of studies about the use of electrospun nanofibers for protective clothing against chemical and biological agents is summarized.
