Highly pure cellulosic polymers obtained from waste lignocellulose offer great potential for designing novel materials in the concept of biorefinery. In this work, alpha-cellulose and nanocrystalline cellulose were isolated from the date palm trunk mesh (DPTM) through a series of physicochemical treatments. Supercritical carbon dioxide treatment was used to remove soluble extractives, and concentrated alkali pretreatment was used to eliminate the lignin portion selectively to obtain alpha-cellulose in approximately 94% yield. Further treatments of this cellulose yielded nanocrystalline cellulose. The structure–property relationship studies were carried out by characterizing the obtained polymers by various standard methods and analytical techniques such as Fourier transform infrared spectroscopy-attenuated total reflection (FTIR-ATR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), energy dispersive X-ray diffraction (EDX-XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Almost 65% yield of pure cellulose was achieved, out of which 94% is the alpha-cellulose. This cellulose shows good thermal stability and crystallinity. The microscopic analysis of the nanocellulose showed a heterogeneous mix of irregular-shaped particles with a size range of 20–60 nm. The percentage crystallinity of alpha-cellulose and nanocellulose was found to be 68.9 and 71.8, respectively. Thus, this study shows that, this DPTM-based low-cost waste biomass can be a potential source to obtain cellulose and nano-cellulose.

In the present study, we report the development of poly (vinyl alcohol) (PVA) and chitosan oligosaccharide (COS)-based novel blend films. The concentration of COS was varied between 2.5–10.0 wt% within the films. The inclusion of COS added a brown hue to the films. FTIR spectroscopy revealed that the extent of intermolecular hydrogen bonding was most prominent in the film that contained 5.0 wt% of COS. The diffractograms showed that COS altered the degree of crystallinity of the films in a composition-dependent manner. As evident from the thermal analysis, COS content profoundly impacted the evaporation of water molecules from the composite films. Stress relaxation studies demonstrated that the blend films exhibited more mechanical stability as compared to the control film. The impedance profiles indicated the capacitive-dominant behavior of the prepared films. Ciprofloxacin HCl-loaded films showed excellent antimicrobial activity against Escherichia coli and Bacillus cereus. The prepared films were observed to be biocompatible. Hence, the prepared PVA/COS-based blend films may be explored for drug delivery applications.

Synergistic formulations were developed with nano-pigments, and their effects on the mechanical properties on steel substrates and structures were evaluated. This paper provides a complete analysis of the epoxy coating, focusing on the incorporation of nano-pigments and their synergistic effects in obtaining higher mechanical properties. This study reports the preparation of epoxy nano-silica composites, their characterization, and the development of coatings based on nano-silica and ZnO particles. In this composite, epoxy resin was incorporated with SiO2 as the main pigment and ZnO as a synergistic pigment to achieve high-performance epoxy coatings for multiple applications. The mechanical properties of these coatings (ESZ1–ESZ3) were evaluated by nanoindentation, and were used to measure the enhanced durability of nanocomposite coatings developed with synergistic formulations with different types of nanoparticles. Their performance was evaluated before and after exposure to a 3.5% NaCl solution to examine the changes of hardness and elastic modulus. The results showed that the nanoindentation technique, in conjunction with Fourier transform infrared spectroscopy and X-ray diffraction, could examine the durability and predict the service life of nanocomposite coatings. A correlation was observed between the modulus and hardness before and after exposing epoxy composite coatings (ESZ1–ESZ3) to a 3.5% NaCl solution.

A tremendous potential has been observed in the designing of long afterglow materials for sensing, bioimaging, and encryption applications. In this study, two different strontium aluminate-based luminescent materials; SrAl2O4: Eu, Dy (S1), and Sr4Al14O25: Eu, Dy (S2) were melt-mixed with polypropylene (PP) matrix, and the phosphorescence properties were evaluated. After excitation at 320 nm, the PP/S1 composite exhibited a green emission and the PP/S2 generated a blue emission at 520 nm and 495 nm, respectively. The emission spectra intensity increased by increasing the content of these luminescent fillers. The attenuated total reflection-Fourier transform infrared (ATR-FTIR) experiments show that no chemical reaction occurred during the melt-mixing process. The differential scanning calorimetry (DSC) results revealed that the total crystallinity of the composites reduced by increasing the amount of the fillers; however, no changes in the temperature of melting (Tm) and crystallization (Tc) of PP were observed. Both fillers improved the impact strength of the composites, but the tensile strength (TS) and modulus (TM) decreased. Poly (ethylene glycol) dimethyl ether (P) plasticizer was used to improve the filler-matrix interaction and its dispersion; nevertheless, it adversely affected the intensity of the luminescence emissions.

The wastage of food products is a major challenge for the food industry. In this regard, the use of edible films and coatings have gained much attention due to their ability to prevent the spoilage of the food products during handling, transport, and storage. This has effectively helped in extending the shelf-life of the food products. Among the various polymers, polysaccharides have been explored to develop edible films and coatings in the last decade. Such polymeric systems have shown great promise in microbial food safety applications. The inclusion of essential oils (EOs) within the polysaccharide matrices has further improved the functional properties of the edible films and coatings. The current review will discuss the different types of polysaccharides, EOs, methods of preparing edible films and coatings, and the characterization methods for the EO-loaded polysaccharide films. The mechanism of the antimicrobial activity of the EOs has also been discussed in brief.

In this work, oleogels of cocoa butter (CB), rice bran oil (RBO), and graphene oxide (GO) were prepared. The prepared oleogels were subjected to various characterization techniques such as bright-field microscopy, X-ray diffraction (XRD), crystallization kinetics, differential scanning calorimetry (DSC), and mechanical studies. The influence of increasing GO content on the in vitro drug release and ex vivo corneal permeation of the model drug (ciprofloxacin HCl—CPH) from the oleogels was also investigated. Bright-field micrographs showed that increment in GO content reduced the size of the globular particles of CB. XRD analysis revealed that CB was crystallized in its β’ and β polymorphic forms in the oleogels, which was in agreement with thermal studies. The mechanical characterization demonstrated that the presence of GO improved the elastic nature and stress-bearing properties of the oleogels. Moreover, GO altered the crystallization kinetics of CB in the oleogels in a composition-dependent manner. The in vitro release of CPH from the oleogels occurred through either Fickian diffusion or fat network relaxation or a combination thereof. Furthermore, the inclusion of GO enhanced the ex vivo permeation of CPH molecules across the caprine cornea. Hence, we concluded that the prepared oleogels could be explored as potential delivery systems for ophthalmic applications.

Metal-plastic composites have the potential to combine enhanced electrical and thermal conductivity with a lower density than a pure metal. The drawback has often been brittleness and low impact resistance caused by weak adhesion between the metal filler and the plastic. Based on our observation that aluminum foil sticks very strongly to poly(ethylene terephthalate) (PET) if it is used as a backing during compression moulding, this work set out to explore PET filled with a micro and a nano aluminum (Al) powder. In line with other composites using filler particles with low aspect-ratio, the tensile modulus increased somewhat with loading. However, unlike most particle composites, the strength did not decrease and most surprisingly, the Izod impact resistance increased, and in fact more than doubled with certain compositions. Thus, the Al particles acted as a toughening agent without decreasing the modulus and strength. This would be the first case where addition of a metal powder to a plastic increased the modulus and impact resistance simultaneously. The Al particles also acted as nucleating agents but it was not sufficient to make PET crystallize as fast as the injection moulding polyester, poly(butylene terephthalate) (PBT).

This paper presents the studies of the development of a high-performance epoxy coating for steel substrates. To this end, it investigated the synergistic effect of incorporating zinc oxide (ZnO) nanoparticles into nanosilica containing epoxy formulations. The mechanical properties of the epoxy coating formulations were improved by modifying the surfaces of the silica nanoparticles (5 wt.%) with 3-glycidoxypropyl trimethoxysilane, which ensured their dispersal through the material. Next, the ZnO nanoparticles (1, 2, or 3 wt.%) were incorporated to improve the corrosion performance of the formulations. The anticorrosive properties of the coatings were examined by electrochemical impedance spectroscopy (EIS) of coated mild steel specimens immersed in 3.5% NaCl solution over different time intervals (1 h to 30 days). Incorporation of the ZnO nanoparticles and the nanosilica into the coating formulation improved the corrosion resistance of the epoxy coating even after long-term exposure to saline test solutions. Finally, to evaluate how the nanoparticles affected the chemical and morphological properties of the prepared coatings, the coatings were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X-ray diffraction (XRD).

The research on ocular drug delivery (ODD) has attracted a continual interest of researchers in the last decade. Herein, we propose to develop oleogel-based formulations for ODD applications. A series of novel nanocomposite oleogels of groundnut oil (GNO) and stearic acid (SA) were prepared, which contained graphene oxide (GO) in the concentration range of 0.00 wt% and 0.05 wt%. The pristine oleogel appeared yellowish-white. However, an increment in the GO content correspondingly imparted a black color hue to the oleogels. Confocal microscopy suggested a considerable branching of the fibrillar network of the fat crystals at lower concentrations of GO. FTIR spectroscopy revealed that GO did not tailor the interactions among the functional groups that are present within the different components of the oleogels. The X-ray diffraction study suggested that the oleogel with the highest GO content was the most crystalline in nature and had a low lattice strain. The mechanical stability of the oleogels was significantly increased when the GO concentration was >0.015 wt%. Thermal analysis of the oleogels confirmed the crystallization of SA in different polymorphic forms. Furthermore, the thermal stability of the fat network structure was higher in the nanocomposite oleogels. The rate of crystallization of SA was higher in the GO-containing oleogels. In general, the in vitro release and ex vivo corneal permeation of the model antibacterial drug (Ciprofloxacin HCl) from the prepared oleogels was Fickian diffusion mediated. Oleogel that contained 0.015% of GO exhibited a ∼2.00 fold increase in the cumulative percentage of drug release. The cumulative percentage of drug permeation through caprine cornea was increased by ∼2.00 folds in the oleogel that contained 0.05% of GO. The prepared oleogels were cytocompatible with human mesenchymal stem cells. The drug-loaded oleogels showed good bactericidal activity against E. coli. In conclusion, GNO/SA/GO-based nanocomposite oleogels were found to have the potential to be explored for ODD applications.

Emulsifiers act as Fat crystal modifiers and can modulate the crystallization process of fats. In this study, we have reported the effect of polyglycerol polyricinoleate (PGPR) on the physicochemical properties of an underutilized vegetable fat “mango butter” (MB). MB-PGPR based formulations were prepared by heat-cool method. Microscopic studies showed that PGPR resulted in the formation of globular MB crystals. XRD and thermal studies conjointly suggested that the MB crystals were predominantly crystallized as β-polymorph. However, PGPR induced imperfections within the MB crystals. FTIR spectroscopy revealed that PGPR considerably varied the local environment of the MB crystals. PGPR also altered the nucleation time and crystallization rate of the MB crystal formation. The MB formulation that contained 2.5% (w/w) PGPR was found to have good mechanical stability. In gist, the addition of PGPR (as a crystal modifier) can help us to influence the crystal behavior and physicochemical properties of the MB fat.

Epoxy formulations containing 1%, 3%, and 5% SiO2 nanoparticles (SNPs) were produced and applied to mild steel substrates in order to improve their thermal, nanomechanical, and abrasion resistance. Field emission scanning electron microscopy (FE-SEM) was used to analyze the dispersion of nanoparticles in the final coating samples, and Energy-dispersive X-ray spectroscopy (EDX) was used to confirm the presence of nanoparticles. Thermogravimetric analysis (TGA) was employed to measure the thermal resistance of the prepared coatings. Conventional techniques were used to measure the impact and scratch resistance. For nanomechanical testing, nanoindentation was performed using a Berkovich-type indenter. Using a taber abraser, the abrasion properties of the coatings were measured. The FE-SEM images indicated good dispersion of the nanoparticles at all three different loading levels. The scratch, impact, and hardness of coatings improved with the addition of the SNPs. Nanomechanical properties, such as hardness and elastic modulus, improved when compared to the unmodified coatings. The thermal and abrasion resistances of the coatings improved with the increase in the SNPs content of the coatings. The highest mechanical, thermal, and abrasion properties were obtained for the coatings with 5% SNP content.

In this study, the effect of different polypropylene (PP) matrices (homopolymer (HPP), impact copolymer (ICP), and recycled polypropylene (rPP)) on the mechanical, morphological, and thermal properties of date palm fiber (DPF)-reinforced PP composites was investigated. The DPFs were treated with an alkali solution, and composites were fabricated with different DPF loadings (5, 10, and 15 wt %) and lengths (less than 2 mm and 8–12 mm). It was found that the tensile properties of the DPF/ICP and DPF/rPP composites were similar to those of the DPF/HPP composites. The addition of fiber to the matrix reduced its tensile strength but increased the modulus. The alkali treatment improved the compatibility between the fibers and the matrix by removing hemicellulose and other impurities. Fourier transform infrared spectroscopy confirmed hemicellulose removal. The morphology of the alkali-treated fractured tensile specimen revealed improved adhesion and less fiber pull out. Differential scanning calorimetry revealed that the alkali treatment enhanced the crystallinity index. Thermogravimetric analysis showed that the addition of DPFs into the PP matrix reduced the thermal stability of the composite. However, the thermal stability of the treated fiber-reinforced rPP and ICP composites was similar to that of the DPF/HPP composite. Hence, rPP can be used as an alternative to HPP with DPFs.

The gelation of the vegetable oils using fat crystals has gained significant attention in recent years. These formulations have been explored for food and pharmaceutical applications. The alteration in the properties of palmitic acid (20% to 40% w/w) and safflower oil oleogels is extensively studied at microscopic and macroscopic levels. The thermal and mechanical stability of the oleogels was improved when the proportion of the palmitic acid content was increased. However, under stress, the fat crystal network junction zones of the oleogels with higher proportions of palmitic acid underwent disruption. The changes in the properties of the oleogels were due to the alteration in the molecular packing, crystallite size, and lattice strain of the fat crystal network. The alteration in the properties was governed by the changes in the extent of inter‐ and intramolecular hydrogen bonding within the components of the oleogels. The oleogels could demonstrate the ability to deliver the drug, voriconazole, across the corneal tissue. Further, the prepared oleogels were biocompatible to murine fibroblast cells and did not elicit adverse reactions when instilled within the ocular sac of rabbits. The results suggest that the oleogels could be tried as ocular delivery vehicles. Practical Applications: The delivery of drug into the internal structure of the eye is a great challenge for the ophthalmologists. Usually not more than 1% of the drug can be delivered through conventional techniques. Various researchers have proposed the use of lipid‐based ocular drug delivery systems. Some of them include solid liquid nanoparticles, emulsions, and liposomes. However the preparation of these formulations require a tedious process. Keeping this in mind, we have proposed to synthesize oleogel as probable ocular drug delivery system. In this study, we proposed a novel palmitic acid and safflower oil‐based oleogel system. The prepared formulations were able to deliver more than 20% of the drug. The oleogels were found to be well tolerant to the corneal tissue. Hence from our preliminary study we can hypothesize that the prepared oleogel could be explored as ocular drug delivery system for maximizing the drug transport across the cornea.

Over the last few decades, hydrogels have attracted the considerable interest of researchers for crafting potential controlled drug delivery systems. It may be attributed to their high water imbibing capacity, soft and rubbery nature, which enables them to exhibit physical properties resembling that of the body tissues. Recently, the environment-sensitive hydrogels have received the special attention of the researchers because of the alteration in their properties in response to a stimulus. The special focus on the environment-sensitive hydrogels has facilitated breakthrough advances in drug delivery (e.g., decrease in dose frequency, increase in the duration of release with reduced side effects, ease of preparation and administration) for the better treatment of various pathological conditions. This paper provides comprehensive information regarding the types of stimuli (i.e., physical, chemical and biological) which can be used to stimulate drug release from the hydrogels and recent advances in the development of stimulus-sensitive hydrogels for drug delivery applications.

Emulsion gel (emulgel) technology has proven to be one of the viable options for designing delivery systems for drugs and probiotics. Such formulations are quite stable as compared to emulsions but possess all the advantages of the biphasic formulations. In our research study, we have developed a series of emulgels using cocoa butter as the fat phase and whey protein isolate (WPI) solution as the aqueous phase for designing efficient delivery systems. The prepared emulgel was characterized by microscopy, XRD, FTIR, mechanical, and electrical analyses. The aqueous phase was present as globular structures which were dispersed uniformly throughout the fat matrix. There was a change in the crystal habit due to hydrogen bonding which ultimately resulted in the alteration in the crystallinity index, viscoelastic and thermal properties of the formulations. An increase in the WPI solution consequently resulted in the decrease in the impedance of the emulgels. The WPI containing emulgels showed better drug diffusion and probiotics viability as compared to the cocoa butter only formulation (control).

Environmental management through effective utilization of biowastes has been a topic of intensive research in recent years. This study examines the effect of pyrolysis temperature on the physical and morphological characteristic of biochar (BC) derived from lignocellulosic wastes. The biochar was prepared by pyrolysing date palm biomass at various temperatures, i.e., 300, 400, 500, 600, and 700 °C. These pyrolysed biochars were then characterized for their carbon content, mineral compositions, chemical functionalities, and morphological structures, for understanding their physicochemical characteristics and microstructural evolution. It was revealed that the pyrolytic condition plays a key role in the formation of biochar microstructure. These biochar samples were then utilized without any further treatments/purifications for their practical application as reinforcement materials for polymer composites. They were blended with a polypropylene matrix by a melt mixing technique followed by injection molding process. The type of biochar was found to significantly affect the composites properties. Differences in microstructure, surface chemistry, and chemical compositions of BCs were observed to be determining factors affecting the compatibility and thermomechanical properties of resulted composites.

The current study deals with the preparation and the characterization of the PVA-CMT-GO films. The PVA-CMT film was translucent in nature and smooth to touch. The addition of GO resulted in the formation of agglomerated structures. XRD studies suggested that the incorporation of GO increased the average crystallite size. The mechanical properties of the films as determined by stress relaxation studies suggested that all the films were viscoelastic in nature. The drug release study showed a decrease in the amount of the drug release with the increase in the GO content. The PVA-CMT-GO films (without drug) showed certain degree of antimicrobial activity owing to the inherent antimicrobial property of GO. The drug loaded films also showed good antimicrobial property. It was found that the prepared films altered the cell proliferation of the human skin keratinocytes in a composition-dependent manner.
