Physicochemical properties of different biodiesel generations synthesized from 11 vegetative oils have been reviewed in purpose of comparing the values of biodiesel physicochemical properties and determination the required feedstock for preferable biodiesel. According to the review, two main factors are affecting the physicochemical properties of yielded biodiesel; the first factor is the raw material of vegetative oil that leads to inherent properties like the energy content, cloud, pour, flash points, kinematic viscosity, cetane and iodine numbers. The other factor is synthesis method and handling procedures of biodiesel production which results in properties such as alcohol and glycerin content, suspended solids, and acid value. This review focuses on 9 important physicochemical properties; Density at 15 °C, kinematic viscosity at 40 °C, cloud, pour, and flash points, heating value, acid value, Cetane number, and iodine number. The standards of ASTM D6751, EN 14214, IS 15607, and MS 2008:2008 are provided to check matching with the physiochemical properties of reviewed biodiesels.

Human activities continue to affect our water quality; it remains a major problem worldwide (particularly concerning freshwater and human consumption). A critical water quality index (WQI) method has been used to determine the overall water quality status of surface water and groundwater systems globally since the 1960s. WQI follows four steps: parameter selection, sub-indices, establishing weights, and final index aggregation, which are addressed in this review. However, the WQI method is a prolonged process and applied to specific water quality parameters, i.e., water consumption (particular area and time) and other purposes. Therefore, this review discusses the WQI method in simple steps, for water quality assessment, based on two multi-criteria decision-making (MCDM) methods: (1) analytical hierarchical process (AHP); and (2) measuring attractiveness by a categorically based evaluation technique (MACBETH). MCDM methods can facilitate easy calculations, with less effort and great accuracy. Moreover, the uncertainty and eclipsing problems are also discussed—a challenge at every step of WQI development, particularly for parameter selection and establishing weights. This review will help provide water management authorities with useful knowledge pertaining to water usage or modification of existing indicators globally, and contribute to future WQI planning and studies for drinking, irrigation, domestic, and industrial purposes.

There is an interest in the sustainable utilization of waste cotton cloths because of their enormous volume of generation and high cellulose content. Waste cotton cloths generated are disposed of in a landfill, which causes environmental pollution and leads to the waste of useful resources. In the present study, cellulose nanocrystals (CNCs) were isolated from waste cotton cloths collected from a landfill. The waste cotton cloths collected from the landfill were sterilized and cleaned using supercritical CO2 (scCO2) technology. The cellulose was extracted from scCO2-treated waste cotton cloths using alkaline pulping and bleaching processes. Subsequently, the CNCs were isolated using the H2SO4 hydrolysis of cellulose. The isolated CNCs were analyzed to determine the morphological, chemical, thermal, and physical properties with various analytical methods, including attenuated total reflection-Fourier transform-infrared spectroscopy (ATR-FTIR), field-emission scanning electron microscopy (FE-SEM), energy-filtered transmission electron microscopy (EF-TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The results showed that the isolated CNCs had a needle-like structure with a length and diameter of 10–30 and 2–6 nm, respectively, and an aspect ratio of 5–15, respectively. Additionally, the isolated CNCs had a high crystallinity index with a good thermal stability. The findings of the present study revealed the potential of recycling waste cotton cloths to produce a value-added product.

The rapid depletion of diesel fuel, increasing energy demand, and environmental pollution concerns are increasing worldwide interest in the production of liquid biofuels. Biofuel (bio‐aviation and biodiesel) is a potential and plausible alternative to diesel fuel to substantially mitigate the environmental impact of future energy demand. Non‐edible crop oil is viewed as a potential feedstock for liquid biofuel production owing to the massive demand for edible oil as a food source. However, the major limitation of utilizing non‐edible crop oil for biodiesel production is the cost due to the high price of feedstocks and the limited supply of large‐scale biodiesel production. Candlenut trees can grow in harsh and arid climates due to low moisture requirements. Therefore, candlenut can be cultivated in the most unused lands, particularly in developing countries along coasts and riverbanks and in deserts and other wastelands unsuitable for edible crops. Additionally, candlenut seed contains a high amount of oil (30%‐60%). Thus, candlenut oil is a promising source for commercial biodiesel production. The present study was conducted to review the possibilities and challenges of utilizing candlenut as a potential feedstock for biodiesel production. Additionally, several important aspects related to candlenut oil processing, such as extraction technology, physicochemical properties, biodiesel production technologies, and advantages and limitations of candlenut biodiesel production are discussed.

An analysis of the performance of a fixed‐plate air‐to‐air energy recovery system on its efficiency and recovered energy for potential building applications in the hot and humid environment was performed. Investigations were executed under controlled laboratory conditions in an energy testing chamber. Tests were carried out with varying operating parameters in terms of airflow rates that ranged from 1.0 to 3.0 m/s, intake air temperature of 28°C, 31°C, 35°C, 40°C and intake relative humidity of 70%, 75% and 80%. The performance was analysed by adopting the calculation methods of the ASHRAE Standard. This study showed that increased airflow rate decreased efficiency. The increase of airflow rate raised the recovered energy of the system. The study indicated that increasing values of intake air temperature (Tin) resulted in the increase of efficiency and recovered energy. A decrease in the efficiency of the system was observed, notably when the intake relative humidity (RHin) increased.

We analyzed real-time measurements of atmospheric carbon dioxide (CO2), with total electricity production and nationwide restrictions phases in China, the United States of America, Europe, and India due to the novel coronavirus COVID-19 pandemic and its effects on atmospheric CO2. A decline of 3.7% in the global energy demand at about 150 million tonnes of oil equivalent (Mtoe) in the first quarter (Q1) of 2020 was recorded compared to Q1 2019 due to the cutback on international economic activities. Our results showed that: (1) electricity production for the same period in 2018, 2019, and 2020 shrunk at an offset of 9.20%, which resulted in a modest reduction (−1.79%) of atmospheric CO2 to the 2017–2018 CO2 level; (2) a non-seasonal, abrupt, and brief atmospheric CO2 decrease by 0.85% in mid-February 2020 could be due to Phase 1 restrictions in China. The results indicate that electricity production reduction is significant to the short-term variability of atmospheric CO2. It also highlights China’s significant contribution to atmospheric CO2, which suggests that, without the national restriction of activities, CO2 concentration is set to exceed 2019 by 1.79%. Due to the lockdown, it quickly decreased and sustained for two months. The results underscore atmospheric CO2 reductions on the monthly time scale that can be achieved if electricity production from combustible sources was slashed. The result could be useful for cost-benefit analyses on the decrease in electricity production of combustible sources and the impact of this reduction on atmospheric CO2.

Raw sheep wool contains various impurities such as wax, suint, dirt, and microorganisms. Water-based cleaning process of sheep wool requires toxic volatile organic compounds that generate a significant portion of toxic effluents. Supercritical CO2 (scCO2) is a waterless technology that has been utilized for sterilization, extraction, cleaning, and drying in various manufacturing sectors. The application of the scCO2 technology in sheep wool processing is cleaner, as it avoids the generation of toxic effluents. scCO2 is a promising technology that can be simultaneously utilized in sheep wool processing for sterilization, extraction of lanolin, and cleaning and drying. Therefore, the present study was conducted to evaluate the potential and limitations of the use of the scCO2 technology for sheep wool processing. Moreover, the properties of sheep wool, the impurities associated with sheep wool fiber, and treatment technology are discussed.

Storage of hydrogen in/on solid‐state materials is predicted from their tendency to adsorb‐desorb hydrogen. It is crucial to find a new class of materials that can reversibly store hydrogen at high rates under reasonable temperature, pressure, and cost conditions. Polymeric materials have recently come to the fore of hydrogen storage technologies because of their reversible capacity, approximately high surface area, and thermomechanical stabilities. Here, we report, for the first time, a polymer for hydrogen storage based on sulfonated polysulfone (SPSU) of above 500 mAh g−1 (~1.8 wt% H) of discharge capacity. Primarily, the SPSU have polymerized from polysulfone (PSU) in the presence of chlorosulfonic acid (ClSO3H). The spectroscopic and elemental analyses confirm the successful sulfonation of PSU. The electrochemical properties of the sample illustrate at high frequency, the resistance is small with slopes of around zero. Cyclic voltammetry affirms a quick ion transfer ability of the host polymer owing to the ion diffusion reaction within the working electrodes. The charge‐discharge efficiency of this system exhibits a stable sequence with around 93% efficiency, comparable with many benchmark commercial batteries. The results clearly emphasize that the SPSU can be individually assigned for hydrogen storage. This study will promote the technology of hydrogen sorption on organic polymers.

Climate change has become a considerable concern for humanity during this anthropocentric era. Scientists believe that the rate of global warming and climate change varies directly with the increase in the concentration of greenhouse gases, particularly carbon dioxide. Urbanization is happening at a higher rate in this era than in any other generation. It was reported that the building sector plays a critical role in the emission of carbon dioxide (CO2) into the atmosphere. Construction of buildings, operation, and utilization of the built environment has led to emissions of a large number of CO2 into the ambient air. Various issues and challenges arise from the building sector in reducing CO2 emissions. The exploitation of non-renewable energy resources, poor building design, and lack of sustainability consideration in urbanization has been holding back CO2 emission mitigation measures in the building sector. Therefore, CO2 emission mitigation plans and schemes are necessary alongside standardized frameworks and guidelines. The strategies to reduce CO2 in the building sector are enforcing standards and policy, conducting impact assessment, adopting low carbon technology, and restricting energy utilization. All stakeholders must play their roles efficiently to reduce CO2 emissions and aid in the fight against climate change.

This study investigated the variation of outdoor air temperature in the shaded area covered by buildings in an urban university campus in Malaysia. In-situ field measurements were conducted to measure the distribution of outdoor air temperature at eight different locations for seven days. Meanwhile, the building-induced shadows were generated using the AutoCAD Revit software to investigate the air temperature change. The study used four urban morphological parameters namely building to greenery ratio, sky view factor (SVF), and height-to-street width (H/W) ratio. The relationship between building-induced shadow and outdoor air temperature (Tout) obtained from the in-situ measurement was investigated. The results showed that the building-induced shadows could lower air temperature. It can be noted that a high ratio of building to greenery resulted in a higher air temperature. In contrast, the area with a low SVF value due to the combination of prolonged shading by buildings and trees had a lower air temperature. Thus, the area with a high building ratio, low greenery ratio, higher SVF value, and low H/W ratio potentially has a higher outdoor air temperature. Conclusively, combination of building shading created by appropriate ratio of building morphology and sufficient greenery able to improve the microclimate of a campus area.

In this chapter, a brief description of the requirements of a hydrogen storage system is given. The weak interaction of hydrogen within pores (sites) needs to be understood in order to design and develop porous materials for hydrogen sorption. The measurements are based on the amount of hydrogen adsorbed as a function of pressure, temperature, the enthalpies of adsorption, and the adsorption/desorption characteristics (Thomas in Hydrogen adsorption and storage on porous materials. Catal. Today 120:389–398, 2007).

Energy conversion is the key input for any proper consideration in energy production and consumption. The primary energy sources such as coal, natural gas, nuclear energy, petroleum, and renewable energy sources are used to generate secondary sources of energy like hydrogen. The secondary energy source made from primary energy sources. Our need for energy to create order in the world stems from 1850, when Rudolf Clausius and William Thomson (Kelvin) stated the second law of thermodynamics. To order the disorderness and randomness of the natural tendency of matter and energy, a constant flow of quality energy through the system should be created. This orderness could be generated by nature and human society on Earth via their potency to structure and acquire energy. This chapter will cover these fundamental principles in detail.

Hydrogen is an ideal candidate to fuel as “future energy needs”. Hydrogen is a light (Mw = 2.016 g mol−1), abundant, and nonpolluting gas. Hydrogen as a fuel can be a promising alternative to fossil fuels; i.e., it enables energy security and takes cares of climate change issue. Hydrogen has a low density of around 0.0899 kg m−3 at normal temperature, and pressure (~7% of the density of air), which is the main challenge in its real applications. It means, for example, 1 kg of hydrogen requires an extremely high volume of around 11 m3. In order to solve this limitation of hydrogen, solid-state hydrogen storage materials are used to store hydrogen efficiently and effectively. In this chapter, an attempt has been developed to provide a comprehensive overview of the recent advances in hydrogen storage materials in terms of capacity, content, efficiency, and mechanism of storage.

The term “energetic materials” are a class of material, which can release stored molecular chemical energy via external stimulations or internal modifications. We aim to take advantage of these opportunities by bringing some logical ideas onto/into the surface of hydrogen storage materials. In addition, hydrogen energy storage systems provide multiple opportunities to enhance flexibility and improve the economics of energy supply systems in the electric grid, gas pipeline systems, and transportation fuels; therefore, it is critical to boost hydrogen storage performance of the materials. The high mobility of the hydrogen and their variable compositions can be enhanced by improving the properties of the host media. In this chapter, the most important factors, which can affect the hydrogen storage performance of the solid-state materials, will be discussed.

Natural fibers are getting attention from researchers and academician for utilization in new technology due to their ecofriendly nature and sustainability. This paper reviews advancements of utilization of natural wool fiber in industry and agriculture. Sheep wool is one of the natural and renewable sources which is widely used in the textile industry to make clothes, rugs, socks, and carpets, besides some uses in agriculture as fertilizers. Recently, wool has become alternative material in some industrial sectors, which increases the value of wool fiber. Increasing demand for alternative materials in buildings sectors has driven the production of sheep wool fibers with comparable and unique properties, for example thermal and sound insulation. Wool with enlarged pores is commercially available for sorption of dyes, oil spill, and volatile organic compounds (Greener Cleaner). Wool is also chemically modified for use in catalytic converter. The unique composition of wool has made it favorable in construction of light aircraft, ships, and trains upholstery. The self-extinguish property makes wool promising as a seal insulator for heat-generating appliances. Substances such as lanoline, ceramide, peptone, and keratin have been proposed for manipulation with wool to be utilized in pharmacotherapy cosmetics, and medical treatment.

Farmers globally withstand a range of carcinogenic exposures, including pesticides (solid and liquid), trace elements, wood dusts, and solar radiation. However, the potential risk and occupational exposure require more attention, since farming is a very diverse occupation with many tasks. Therefore, the aim of this study is to assess potential risks and occupational exposure of pesticides among rice farmers in Malaysia. Field data are collected in a village located in the Northern Peninsular of Malaysia. Thirty-two farmers (which are assigned as F1 to F32) are selected for a thorough look at the farms. In the Northern Peninsular of Malaysia, four different pesticides are frequently used by the rice farmers including buprofezin, chlorpyrifos, difenoconazole, and lambda cyhalothrin. In order to follow up the right trend of exposure rate (ER), the farmers categorise/rank into two levels, 3 and 4, with respect to hazard rating (HR) and frequency rating (FR), and in terms of magnitude rating (MR), they assort into 3 to 5 levels. Finally, a risk matrix is designed during risk assessment to calculate the risk rating (RR). It can be deduced that the rice farmers are a high-risk group in relation to harmful exposure of pesticides under categories 3 to 5. Since the farmers are exposure to a wide variety of different carcinogens, several risk minimisation strategies (as recommended) are urgently required, in order to reduce the impact of exposure.

Hydrogen energy storage has been considered as a key enabler for exploring novel materials with unique structures and properties, however, inadequate storage capacity, and instability leading to low performances. Metal organic compounds contain a core transition metal ion in accordance to their organic environment, allowing localized and enhanced hydrogen storage. Here, we show a superior hydrogen storage system, with around 1850 mAh/g discharge capacity and around 74% charge-discharge efficiency, performing rectangular nanocuboids beta copper phthalocyanine (β-CuPc). Primarily, β-CuPc has been synthesized in ethylene glycol (EG) via stepwise thermal treatments up to ∼185 °C with demonstrating its morphological and structural properties. Interestingly, unique surface morphology of as-synthesized β-CuPc (with about 163 nm width and 47 nm height) comes to our preliminary expectations as a relevant host for hydrogen sorption. Our work can expand into the classes of materials that can be used efficiently in hydrogen storage technology, and also opening a new channel to the wide range of mobile applications, either in academia or industries.
