This study employed bromelain enzyme derived from pineapple (Ananas comosus) peel waste for collagen extraction and compared the procedure with conventional acetic acid extraction. The recovery of bromelain enzyme at 30–70% ethanol precipitation exhibited a 2.21-fold purification and a 98% yield. Response surface methodology (RSM) analysis revealed that bromelain enzyme-extracted collagen (BEC) yielded 82.20% at a hydrolysis time of 18.39 h, a mixing ratio of 22.38, and a temperature of 39.32 °C. In contrast, a lower yield of 66.94% was observed in the case of acetic acid-extracted collagen (AEC) at a hydrolysis time of 18.66 h, a mixing ratio of 19.41, and a temperature of 27.09 °C. Fourier transform infrared spectroscopy (FTIR) confirmed the successful extraction of both AEC and BEC. Thermogravimetric analysis (TGA) indicated the higher thermal stability of BEC compared to AEC. X-ray Diffraction (XRD) displayed characteristic peaks of collagen in the range of 2θ of 15–25°, affirming that BEC (sharp peak at 19.49°) is more crystalline than AEC (broadening peak at 19.88°). Elemental analysis revealed a higher nitrogen content (6.78%) in BEC, indicating a higher protein content than that of AEC (6.31%). Furthermore, antimicrobial activity, cytotoxicity evaluation, and heavy metal analysis revealed the potential applications of collagen in cosmetics, biomaterials, and tissue engineering.}, journal={Journal of Cleaner Production}, author={Munmun, Sajneen Akter and Rashid, Taslim Ur and Rahman, Mohammed Mizanur}, year={2024}, month={Jan} } @article{islam_uddin_rashid_shahruzzaman_2023, title={Cellulose Acetate-based Membrane for Wastewater Treatment—A State-of-the-Art Review}, url={http://dx.doi.org/10.1039/d3ma00255a}, DOI={10.1039/d3ma00255a}, abstractNote={Efficacy of cellulose acetate-based membranes for wastewater treatment has been critically evaluated.

The nanofibrous mat was thermally crosslinked by heat curing to make it stable in neutral, acidic, and basic environments. The prepared nanofibrous mat was characterized by attenuated total reflectance infrared spectroscopy (ATR-IR), thermogravimetry (TGA), X-ray diffraction (XRD), and water dissolution properties. The detailed experimental results revealed that the nanomat prepared from CH: PVA (2:3) yielded better stability in an aqueous solution after thermal crosslinking. The nanofibrous mat was used as adsorbent and its adsorption properties were evaluated from the adsorption behaviour of methylene blue (MB), a common cationic dye. The adsorption results demonstrated that the nanomat showed maximum adsorption capacity of 99.9 mg g−1 with 88.8% removal efficiency at pH 12. The adsorption parameters were optimized and revealed to be highly pH sensitive, with 12.0 being the optimum pH for the highest dye removal. The experimental results revealed that the adsorption capacity of the nanofibrous mat grew with increasing initial dye concentration and decreased with increasing adsorbent doses. The thermodynamic study indicated that the adsorption kinetics (R2 > 0.99) followed pseudo-second-order equation, and the equilibrium data was the best suited by the Langmuir model (R2 > 0.99). On the other hand, the electrospun nanofibrous mat showed significantly better adsorption than the prepared CH-PVA composite film. The results for cationic dye adsorption suggest that the potential broader applications of collagen hydrolysate-based nanofibrous mat for pollution control may include its use as potential adsorbent for wastewater treatment.}, journal={Cleaner Engineering and Technology}, author={Sitab, Abrar A. and Tujjohra, Fatema and Rashid, Taslim Ur and Rahman, Mohammed Mizanur}, year={2023}, month={Apr} } @article{afrin_shahruzzaman_haque_islam_hossain_rashid_ahmed_takafuji_rahman_2022, title={Advanced CNC/PEG/PDMAA Semi-IPN Hydrogel for Drug Delivery Management in Wound Healing}, volume={8}, ISSN={["2310-2861"]}, url={https://www.mdpi.com/2310-2861/8/6/340}, DOI={10.3390/gels8060340}, abstractNote={A Semi Interpenetrating Polymer Network (semi-IPN) hydrogel was prepared and loaded with an antibiotic drug, gentamicin, to investigate the wound healing activity of this system. The semi-IPN hydrogel was synthesized by combining natural polymer cellulose nanocrystal (CNC) and synthetic polymer polyethylene glycol (PEG) and poly (N,N′-dimethyl acrylamide) (PDMAA), which was initially added as a monomer dimethyl acrylamide (DMAA). CNC was prepared from locally obtained jute fibers, dispersed in a PEG-NaOH solvent system and then mixed with monomer DMAA, where polymerization was initiated by an initiator potassium persulphate (KPS) and cross-linked by N,N′-methylenebisacrylamide (NMBA). The size, morphology, biocompatibility, antimicrobial activity, thermal and swelling properties of the hydrogel were investigated by different characterization techniques. The biocompatibility of the hydrogel was confirmed by cytotoxicity analysis, which showed >95% survival of the BHK-21, Vero cell line. The drug loaded hydrogel showed antimicrobial property by forming 25 and 23 mm zone of inhibition against Staphylococcus aureus (gram-positive) and Escherichia coli (gram-negative) bacteria, respectively, in antimicrobial analysis. At pH 5.5, 76% of the drug was released from the hydrogel within 72 h, as observed in an in vitro drug release profile. In an in vivo test, the healing efficiency of the drug loaded hydrogel was examined on a mice model with dorsal wounds. Complete healing of the wound without any scar formation was achieved in 12 days, which revealed excellent wound healing properties of the prepared drug loaded semi-IPN hydrogel.

N95 respirator have become a critical component for reducing SARS-CoV-2 transmission and controlling the scale of the COVID-19 pandemic. However, a major dispute concerning the protective performance of N95 respirators has erupted, with a myriad of healthcare workers affected despite wearing N95 masks. This article reviews the most recent updates about the performance of N95 respirators in protecting against the SARS-CoV-2 virus in the present pandemic situation. A brief overview of the manufacturing methods, air filtration mechanisms, stability, and reusability of the mask is provided. A detailed performance evaluation of the mask is studied from an engineering point of view.

For this purpose, a series of bifunctional nanohybrids containing different proportions of naturally occurring biopolymer chitosan and ternary photocatalyst made of kaolinite, TiO2, and ZnO were prepared through the dissolution of chitosan in acid and subsequent deposition on ternary photocatalyst. The characterization through Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy dispersive X-ray spectrum (EDS) have confirmed the successful fabrication of nanohybrids from TiO2 and chitosan. The adsorptive separation of Orange G from the aqueous solution and subsequent degradation under solar irradiation was thoroughly studied by recording the λmax value of dye in the ultraviolet–visible (UV-Vis) spectrophotometer at various operating conditions of pH, dye concentration, contact time, and compositional variation. The nanohybrid (TP0.75CS0.25) fabricated from 75% ternary photocatalyst (w/w) and 25% chitosan (w/w) removed 97.4% Orange G within 110 min at pH 2.5 and 10 mg/L dye concentration. The relative contribution of chitosan and ternary composite on dye removal was understood by comparing the experimental results in the dark and sunlight. Recyclability experiments showed the suitability of the nanohybrid for long-term repeated applications. Equilibrium experimental data showed a better correlation with the Langmuir isotherm and pseudo-second-order kinetic model. The rapid and nearly complete removal capacity, long-term reusability, and simple fabrication technique make this novel nanohybrid a promising advanced material for removing hazardous azo dyes from industrial effluents.}, number={10}, journal={JOURNAL OF COMPOSITES SCIENCE}, author={Hossain, Mohammad Rahat and Rashid, Taslim Ur and Lata, Nadira Parvin and Dey, Shaikat Chandra and Sarker, Mithun and Shamsuddin, Sayed Md}, year={2022}, month={Oct} } @misc{akter_bhattacharjee_dhar_rahman_haque_rashid_kabir_2021, title={Cellulose-Based Hydrogels for Wastewater Treatment: A Concise Review}, volume={7}, ISSN={["2310-2861"]}, url={https://www.mdpi.com/2310-2861/7/1/30}, DOI={10.3390/gels7010030}, abstractNote={Finding affordable and environment-friendly options to decontaminate wastewater generated with heavy metals and dyes to prevent the depletion of accessible freshwater resources is one of the indispensable challenges of the 21st century. Adsorption is yet to be the most effective and low-cost wastewater treatment method used for the removal of pollutants from wastewater, while naturally derived adsorbent materials have garnered tremendous attention. One promising example of such adsorbents is hydrogels (HGs), which constitute a three-dimensional polymeric network of hydrophilic groups that is highly capable of adsorbing a large quantity of metal ions and dyes from wastewater. Although HGs can also be prepared from synthetic polymers, natural polymers have improved environmental benignity. Recently, cellulose-based hydrogels (CBHs) have been extensively studied owing to their high abundance, biodegradability, non-toxicity, and excellent adsorption capacity.

In order to obtain poly(acrylic acid)-graft-modified clay composite (PAA-g-MC), the growing PAA chain was ‘grafted onto’ the modified clay surface. The structural properties of the composite adsorbent were studied by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray fluorescence (XRF), and scanning electron microscope (SEM). Thermal properties of the composites were measured by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The effect of different process parameters such as pH of dye solution, contact time, initial concentration of dye, and adsorbent amount on the removal efficiency of methylene blue (MB) from aqueous solution was evaluated by batch experiments. Characteristics data from XRD and XRF for raw clay and acid-treated clay showed that Bijoypur clay is rich in kaolinite, which contains a significant amount of quartz. However, treatment with HCl reduces 55% of quartz and increases the percentage of kaolinite that made it suitable for adsorbent used. Adsorption results showed that PAA-g-MC composite showed a maximum adsorption of 162.3 mg g−1 of 100 mg L−1 MB dye solution at pH 7.25 after 80 min of adsorption using 0.03 g L−1 of the adsorbent. Langmuir and Freundlich adsorption isotherms were studied and the equilibrium adsorption data were found to be well fitted with the Langmuir adsorption isotherm. The interaction between adsorbent and MB molecules was explained by chemisorption, as suggested by the pseudo-second-order kinetic model.

Fish scales of different physical forms were applied for the removal of dyes (acid red 1 (AR1), acid blue 45 (AB45), and acid yellow 127 (AY127)) from textile dye solution by absorption process. An astounding phenomenon, gelation of the treated solution, was noticed when it was aged for a certain period. The absorption of dye by FS was confirmed and quantified by FT-IR and UV-visible spectroscopy analyses, respectively. Process optimization revealed that pristine FS showed better gelation efficacy compared to pulverized FS. The gelation process was successful only when the dye solution contained acid and salt. As most of the textile effluents contain acids and salts in the discarded dye solution, this gelation process implies an obvious indication of the saving process and chemical cost in textile waste treatment. The jellified wastewater was characterized by exploring the rheological properties. Based on these analyses, potential application areas have been discussed.}, number={3}, journal={GELS}, author={Kabir, S. M.

The use of various types of functional biopolymers as scaffold materials in hydrogels has become of great interest not only as an underutilized resource but also as a new functional material of high potential in various fields. Among them, gelatin has been considered as highly potential candidate to be utilized as hydrogel component because of its hydration properties such as swelling and solubility; gelling behavior such as gel formation, texturizing, thickening, and water-binding capacity; and surface behavior like emulsion and foam formation, stabilization, adhesion and cohesion, protective colloid function, and film-forming capacity. In addition, its properties of biocompatibility, low toxicity, antimicrobial activity, and biodegradability make it suitable for diversified biomedical applications. Many works have been reported in various scientifically reputable journals and publications worldwide that seem to have potential or satisfactory contribution of gelatin-based hydrogels. Numerous fields of application of gelatin hydrogels include, not limited to, usage as safer release system in agrochemicals, nutrient carriers for plants, drug and cell carrying devices, bioadhesives, wound healing, tissue engineering, etc. The purpose of this chapter is to compile the recent information on developments in gelatin-based hydrogel preparation, as well as new processing conditions and potential novel or improved applications.}, booktitle={Polymers and Polymeric Composites: A Reference Series}, publisher={Springer International Publishing}, author={Rashid, Taslim Ur and Sharmeen, Sadia and Biswas, Shanta and Ahmed, Tanvir and Mallik, Abul K. and Shahruzzaman, Md. and Nurus Sakib, Md. and Haque, Papia and Rahman, Mohammed Mizanur}, year={2018}, pages={1–41} } @inbook{rahman_islam_islam_zaman_ahmed_biswas_sharmeen_rashid_rahman_2018, title={Morphological Characterization of Hydrogels}, ISBN={9783319765730 9783319765730}, ISSN={2510-3458 2510-3466}, url={http://dx.doi.org/10.1007/978-3-319-76573-0_28-1}, DOI={10.1007/978-3-319-76573-0_28-1}, abstractNote={Hydrogels are physically or chemically cross-linked polymer networks that are able to absorb large amounts of water.

Morphology and properties of the composites (different weight ratio of MC and CHT) have been studied and compared with those of pure CHT and MC. Purification and modification of Bijoypur clay were investigated by X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier transformed infrared spectroscopy (FTIR) analyses. The fabrication of CHT-MC composites was confirmed by FTIR analysis. Thermogravimetric analysis (TGA) and differential scanning colorimetry (DSC) were used to investigate the thermal stability of the composites. It was observed that dispersed clay improves the thermal stability and enhances the hardness of the matrix systematically with the increase of clay loading.

Chitin at different concentration (1-20% of PLA) reinforced PLA films (CTP) were fabricated by solvent casting process and laminated chitin-PLA composites (LCTP) were prepared by laminating PLA film (obtained by hot press method) with CTP also by hot press method at 160 °C. The effect of variation of chitin concentration on the resulting laminated composite's behavior was investigated. The detailed physico-mechanical, surface morphology and thermal were assessed with different characterization technique such as FT-IR, XRD, SEM and TGA. The FTIR spectra showed the characteristic peaks for chitin and PLA in the composites. SEM images showed an excellent dispersion of chitin in the films and composites. Thermogravimetric analysis (TGA) showed that the complete degradation of chitin, PLA film, 5% chitin reinforced PLA film (CTP2) and LCTP are 98%, 95%, 87% and 98% respectively at temperature of 500 °C. The tensile strength of the LCTP was found 25.09 MPa which is significantly higher than pure PLA film (18.55 MPa) and CTP2 film (8.83 MPa). After lamination of pure PLA and CTP2 film, the composite (LCTP) yielded 0.265-1.061% water absorption from 30 min to 24 h immerse in water that is much lower than PLA and CTP. The increased mechanical properties of the laminated films with the increase of chitin content indicated good dispersion of chitin into PLA and strong interfacial actions between the polymer and chitin.

It is the most abundant plant cell wall component of the biosphere and the most plentiful biological compound on terrestrial earth. The successful conversion of cellulosic waste from domestic, industrial, and municipal sources through economically feasible processes to valuable by-products has long been admitted as a desirable endeavor. The degradation of cellulosic materials has gained increasing attention due to its worldwide availability and enormous potential for transforming them into sugars, fuels, and chemical feedstocks. Enzymatic hydrolysis of cellulosic biomass holds tremendous promise due to the high specificity and production of high yields of glucose without generation of degradation products, unlike acid/alkali hydrolysis. It has lower utility cost and hydrolysis occurs under mild reaction conditions. Microorganisms that degrade cellulose are abundant and universal in nature. The enzymatic hydrolysis of cellulose requires the use of cellulase enzyme. Fungi and bacteria are the main cellulase-producing microorganisms. A “twofold” benefit could be achieved through a sustainable bioconversion of biomass by cellulase enzyme. First, it would reduce the amount of cellulosic waste and diminish its effects on our environment; and second, the bioconversion of waste would be an alternative source of fuel energy to shrink our growing dependence on fossil fuels.}, booktitle={New and Future Developments in Microbial Biotechnology and Bioengineering}, publisher={Elsevier}, author={Khan, M.

It is produced commercially by deacetylation of chitin, which is the structural element in the exoskeleton of crustaceans (such as crabs and shrimps) and the cell walls of fungi. In the work reported, we developed a facile technique for the preparation of chitosan by irradiating prawn shell at various intensities from 2 to 50 kGy. It was observed that γ‐irradiation of prawn shell increased the degree of deacetylation (DD) of chitin at a relatively low alkali concentration during the deacetylation process. Among the various irradiation doses applied to prawn shell, a dose of 50 kGy and 4 h heating in 50% NaOH solution yielded 84.56% DD while the chitosan obtained from non‐irradiated prawn shell with the same reaction conditions had only 74.70% DD. In order to evaluate the effect of γ‐irradiation on the various physicochemical, thermomechanical and morphological properties, the chitosan samples were again irradiated (2–100 kGy) with γ‐radiation. Molecular weight, DD, thermal properties with differential scanning calorimetry and thermogravimetric analysis, particle morphology by scanning electron microscopy, water binding capacity (WBC), fat binding capacity (FBC) and antimicrobial activity were determined and the effects of various γ‐radiation doses were assessed. The DD, WBC, FBC and antimicrobial activity of the chitosan were found to improve on irradiation. It was obvious that irradiation caused a decrease of molecular weight from 187 128 to 64 972 g mol−1 after applying a radiation dose of 100 kGy which occurred due to the chain scission of chitosan molecules at glycosidic linkages. The decrease of molecular weight increased the water solubility of the chitosan, the extent of which was explored for biomedical applications.

The detailed experimental studies demonstrated that nonirradiated chitin deacetylated by 40% NaOH solution showed 72% degree of deacetylation (DD), however 50 kGy irradiated chitin, deacetylated by 20% NaOH demonstrated 81.5% DD. Chitosan in solid state as obtained from γ-irradiation of chitin was further irradiated by different doses (2–100 kGy) of gamma irradiation and the effects of irradiation on the molecular weight, thermo-mechanical by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), and antimicrobial properties were evaluated with respect to nonirradiated chitosan sample. Gamma irradiation of chitosan with a dose of 100 kGy caused a decrease in average molecular weight from 1.9×105 to 6.5×104 Da and thus increased its solubility in water. Nonirradiated and γ-irradiated chitosan at concentration 1% (w/w) in water were prepared and used to evaluate of its potentiality for growth stimulation of Malabar spinach. The chitosan solution was sprayed on the specimen plants and neighboring soil where germinations were taken place and various plant growth parameters such as plant height, number of leaves, leaf areas, dry and wet weight of the plants and roots were investigated. The details study revealed that application of 30 kGy irradiated chitosan yielded 60% higher growth of the Malabar spinach than that obtained from nonirradiated chitosan. The data are consistent with preliminary results from field experiments and unambiguously confirms that a minor amount of chitosan has a profound effect on the growth and development of Malabar spinach.}, number={1}, journal={Radiation Physics and Chemistry}, publisher={Elsevier BV}, author={Rahman, Mohammed Mizanur and Kabir, Shahriar and Rashid, Taslim Ur and Nesa, Bodrun and Nasrin, Romana and Haque, Papia and Khan, Mubarak A.}, year={2013}, month={Jan}, pages={112–118} } @article{khan_rahman_nesa_nasrin_molla_islam_rashid_haque_mustafa_khan_et al._2013, title={Preparation and characterization of poly (ethylene glycol) grafted Ca-alginate fibers by γ-irradiation for biomedical applications}, volume={27}, ISSN={0169-4243 1568-5616}, url={http://dx.doi.org/10.1080/01694243.2012.705099}, DOI={10.1080/01694243.2012.705099}, abstractNote={Radiation processing, being a physical process, is an environmentally friendly alternative to chemical modifications. It is economically viable, safe, and possesses several advantages over other conventional methods employed for modification and grafting. To improve the physico-mechanical properties of Ca-alginate fiber (CaAF), poly (ethylene glycol) (PEG) was grafted by applying γ-radiation of different intensities. The effect of γ-irradiation on the physico-mechanical, thermal, morphological, thermal and water aging, water, and simulated body fluid (SBF) uptake were evaluated. FT-IR results confirmed that PEG was successfully grafted onto Ca-alginate fibers by γ-irradiation. From the detailed experimental results, irradiation doses and PEG concentration were optimized for grafting processes. The results showed that 50% PEG and 2.5 kGy irradiation dose yielded the highest tensile strength. Differential scanning calorimetric (DSC) analysis showed that with increasing γ-intensity a decrease of dehydration temperature of the fibers had occurred. On the other hand, the glass transition temperature (T g) increased with increasing irradiation dose. The tensile cracked surfaces of the grafted alginate fibers were analyzed by scanning electron microscope (SEM) in order to monitor their surface morphologies. The SEM images of the cracked surfaces demonstrated that spherical shape rods were present for irradiated fiber sample while no such rods were observed for non-irradiated fibers. The characteristic data obtained from SBF and water uptake, and water and thermal aging experiments indicated that CaAF grafted with 50% PEG by applying 2.5 kGy γ-irradiation can be potentially employed for biomedical purposes, such as surgical suture.}, number={2}, journal={Journal of Adhesion Science and Technology}, publisher={Informa UK Limited}, author={Khan, Md.

Fibre content of the composite was varied from 5–30% by weight and physico-mechanical properties of the composites were measured. Surface morphology as observed by SEM showed good interface adhesion between rayon and PP matrix. Furthermore inclusion of rayon (up to 15% fiber inclusion) in the composite increased tensile, bending and hardness properties. As the fiber content in the composite increased more than 15%, physico-mechanical properties decreased due to the decrease of fiber matrix adhesion. The change of tensile properties due to environmental aging was carried out by keeping the composite under soil for 1 month and tensile properties were measured periodically. The aging result suggests that composites retained about 75% of its original tensile and bending strength even after 1 month soil burial. The modified fibers were also used for the study. As such the fibers were treated with vinyl-trimethyoxysilane and methanol solution and irradiated under UV before being used with PP in extruder.
