  • Effect of Process Parameters on Particle Size and Morphology of
           Telmisartan in Anti-solvent Crystallization
    • Abstract: This study aimed to reduce the particle size of the poorly water-soluble drug telmisartan up to nano-range by anti-solvent crystallization method. In the present experiments, dimethyl sulfoxide (DMSO) as a solvent and deionized water as an anti-solvent have been utilized. The study was carried out using important operating parameters, namely drug loading, volume of anti-solvent, injection rate, and crystallization temperature. With a higher loading of the drug at 15 mg/ml, drug particle of (334 nm) size was achieved. With a higher volume of anti-solvent, further reduction in particle size (329 nm) was achieved. Smaller particles having (320 nm) size were achieved when injection rate was maintained at 10 ml/min and a lower crystallization temperature. Recrystallized telmisartan nanoparticles were characterized using dynamic light scattering, scanning electron microscopy, X-ray diffraction, and differential scanning calorimetry. The studies revealed that the recrystallized telmisartan was in a crystalline state.

  • Effect of pH on Antibacterial Activity of Textile Fibers
    • Abstract: In this study, four textile fibers, cationized cotton, polyester, nylon, and spandex were used to evaluate the antibacterial activity at different pH values (6, 5, and 3). The results show that spandex fiber is showing the highest inhibition zone (41.17%) at a pH value of 6 as compared to cationized cotton (0%), nylon (0%), and polyester (0%). As the pH reduces to 5, cationized cotton and nylon are also showing the inhibition zone of 16.66% and 23.07%, respectively. Further decreased in pH up to 3, the area of inhibition zone also increases to 23.07% for cationized cotton and nylon by 33.33%. But in the case of polyester, the inhibition zone remained at 0% for all the pH values. Changes in the size of the inhibition zone in antibacterial testing at different pH are due to the shifting of zeta potential toward positive values resulting from the disassociation of surface chemical groups. This is explained based on FT-IR analysis and the measured zeta potential (surface charge) at different values of pH of each fiber. It is observed that the fiber itself can have antibacterial behavior at a given pH value of the aqueous medium. So, there is potential for the applications of these materials in the field of health care and hygiene without using any antibacterial finishing chemicals in the aqueous medium at 3–6 pH values.

  • Comparative Studies on Thermal Comfort Properties of Eri Silk, Mulberry
           Silk, Wool and Linen Fibres
    • Abstract: Thermal comfort properties of eri silk, mulberry silk, wool and linen fibres have been studied in this article. Four types of fabrics were made by using spun yarns of eri silk, mulberry silk, wool and linen fibres in weft direction and polyester multifilament yarn in warp direction. Thermal comfort properties of these fabrics have been studied by measuring the air permeability, moisture absorption, thermal and moisture transmission through the fabrics. The thermal properties were measured with Alambeta instrument and wicking of the fabrics was measured by using a vertical wicking tester. Among the four samples, wool fabrics exhibit highest thermal resistance and lowest thermal absorption value; whereas eri silk, mulberry silk and linen fabrics displayed lower thermal resistance values and also higher thermal absorption values, without much significant difference among them. It is observed that the linen fabrics have highest air permeability, followed by wool and then silk fabrics. Lowest air permeability properties of eri and mulberry silk are found to significantly influence the thermal behaviour of silk samples. Highest water vapour permeability was observed in case of wool fabric. Highest wicking and absorbency has been observed in case of mulberry and eri silk, respectively. The results emphasize that the eri silk and mulberry silk samples with high thermal absorbency, wickability, moisture absorbency and very good water vapour permeability coupled with low thermal resistance are suitable for summer wear clothing and at the same time these samples also possess very low air permeability and very good water vapour permeability signifying their appropriateness as thermal wear for windy conditions.

  • Effect of Iso-Butanol Blends in Spark Ignition Engine as an Alternative
    • Abstract: The article presented is concerned with studying the effect of ethanol, and iso-butanol concentrations in a spark ignited, single-cylinder four-stroke engine on the engine parameters such as performance, combustion, and emission. The engine performance characteristics such as specific fuel consumption, brake thermal efficiency, and in-cylinder pressure were examined for different engine's operational loads. Similarly, the emission parameters such as CO, HC, and NOx were analyzed. Results showed that the influence of iso-butanol and ethanol improved the thermal by 6% than that of petrol. As a result of adding iso-butanol and ethanol with petrol, fuel consumption reduction can be observed. The CO, NOx, and HC emission were noted as 1.25% by vol, 146 ppm, and 175 ppm, respectively, whereas the CO2 is noted as 7.7% for 5% ethanol and 15% Iso-butanol. The optimum concentration of iso-butanol and ethanol was found as 15 and 5%, respectively, which improved the engine operating parameters and decreased the emission produced. The emission such as CO, Nox, and HC shows a significant reduction; on the other hand, the CO2 showed a drastic rise for the optimized blend proving the progression of complete combustion

  • Nanofibres for Clean Air Breathing
    • Abstract: Air pollution is a global concern for human health. Air pollution leads to respiratory diseases, cancer, and even death. Tiny sized particulate matter (PM) and volatile organic compounds (VOCs) are the main health hazards in air. Functional nanofibres can trap these pollutants. This paper studied the electrospun nanofibre membrane (ENM) for protection against smaller PM (≤ 2.5 μm) and VOCs. The ENM of 1.2 g/m2 areal density was prepared using electrospinning. Due to the low ENM areal density, the air resistance was small, which makes it suitable for respiratory filtration. The ENM was characterised using scanning electron microscopy and capillary flow porometry. Its filtration efficiency and VOC adsorption capacity were determined using a typical laboratory set-up. The ENM showed excellent filtration efficiency (≥ 95%) for PM 0.3 μm. It also effectively adsorbed benzene VOC mainly due to its surface modification with β-cyclodextrin. The electrospun nanofibre membrane provides multifunctional protection and aids in pollution-free air breathing. This nanotechnology-based material has the potential to be used in air filtration for clean air.

  • Desirability Analysis of Multiple Responses for Electrocoagulation
           Remediation of Paper Mill Wastewater by Using a Central Composite Design
    • Abstract: The present study illustrates the electrocoagulation remediation of paper mill wastewater for multiple response optimization. Multiple response optimization can be combined into one desirability function. All variables and responses varied for a unique global solution. The effect of basic electrocoagulation process variables pH (3–10), conductivity (3.15–10 mS/cm), electrode distance (1–2.5 cm) and current density (5–20 mA/cm2) on four response parameters such as chemical oxygen demand, color, total dissolved solids and total organic carbon has been analyzed experimentally and statistically. The global solution for these variables and responses obtained by software over a hundred design points. For unit desirability function variables conditions were pH 7.49, Conductivity 8.34 mS/cm, electrode distance 2.06 cm and current density 9.32 mA/cm2. In these global variable conditions, responses were observed to be COD 70.19%, Color 75.03%, TDS 70.69% and TOC 71.93%, respectively.

  • Photocatalytic Degradation of Sugar and Distillery Industry Effluent
    • Abstract: In the present study, photocatalytic degradation of recalcitrant pollutants present in the sugar and distillery industry was investigated using TiO2 as photocatalysts. The efficiency of degradation was quantified by several parameters such as the effect of varying pH, initial concentration, catalyst loading, and UV light intensity. The degradation was measured in terms of COD reduction using Titrimetric, Mid-Level method for sugar, and distillery industry wastewater. It was observed that in comparison with UV/TiO2 system exhibited a higher rate of COD degradation. The degradation was found to follow pseudo-first-order kinetics. On optimization of various parameters, it was found that TiO2 (Degussacp-225) could bring about COD reduction within 6 h for an initial concentration of 2000 ppm of the COD and a catalyst loading of 1 g/L. Increment in UV exposure intensity further enhanced the degradation rate.

  • The Effect of Fluorine Doping on Structural and Dielectric Properties of
           Molecular Ferroelectric Diisopropylammonium Bromide
    • Abstract: An interest in organic molecular ferroelectrics is increasing due to their numerous advantages such as eco-friendly, lightweight, cost-effective, scalable and low processing temperatures. In the present work, the organic molecular ferroelectric diisopropylammonium bromide (DIPAB) and 50% fluorine-doped diisopropylammonium bromide (DIPABF) are synthesized in the form of polycrystalline powder using solution growth technique. The X-ray diffraction measurements done on as prepared DIPAB and DIPABF samples confirmed the room temperature orthorhombic phase (P212121). The temperature-dependent dielectric studies are carried out on DIPAB confirmed its phase transitions nearly at 416 K and 429 K. But, DIPABF has shown a frequency-dependent transition near 429 K and the transition at 416 K is suppressed. It is also observed from the temperature-dependent dielectric constant and dielectric loss curves that the ferroelectric to paraelectric transition at 429 K is broad in DIPABF and it is frequency dependent. This confirms the presence of dielectric relaxation in DIPABF. The origin of such dielectric relaxation is explained with respect to temperature-dependent dipole rotation and electronegativity. Overall, DIPAB and DIPABF organic polycrystalline ferroelectric materials have been successfully synthesized and demonstrated its temperature-dependent dielectric relaxation in DIPABF.

  • XRD and TG-DTG Probes for Thermal Stability and Durability of CuPbI 3 : Eu
           +2 /Eu +3 and CuPbI 3 Perovskite as Catalysts
    • Abstract: The remarkable hole transport abilities of copper iodide and ionic transportation abilities of lead iodide help in enhancement of their electrical and catalytic properties. The combination of the two has resulted in a perovskite with excellent catalytic and electrical properties. To improve the aforementioned properties of CuPbI3 perovskite, it was doped with EuO and Eu2O3. CuPbI3 and CuPbI3: Eu+2/Eu+3 perovskites were synthesized using combustion method. Four CuPbI3: Eu+2/Eu+3 perovskites with varying compositions were prepared by doping 10, 20, 30 and 40% of Eu+2 and Eu+3 into CuPbI3 perovskite lattice in equal amounts. The structural and thermal characteristics were analyzed using TG-DTG and XRD analysis techniques. The results obtained from XRD analysis suggest that the degree of crystallization increases with an increase in doping of Eu+2/Eu+3. Also, an increase in other structural parameters such as unit cell volume and crystallite size with doping of Eu+2/Eu+3 indicate potential boost in catalytic properties of the aforementioned perovskites. The TG-DTG analysis results indicate that the CuPbI3 perovskite is more stable at lower temperatures (50–430 °C) while CuPbI3: Eu+2/Eu+3 (10–40%) are more thermally stable in the temperature range of 50–505 °C. Also, the overall weight loss was found to be significantly higher in case of CuPbI3 as compared CuPbI3: Eu+2/Eu+3 as indicated by the TG-DTG analysis results. These enhanced structural and catalytic properties of CuPbI3 perovskite escalate its applicability as photovoltaic cells and catalysts.

  • Inter-Comparison of Two Instrumental Test Methods for Diameter Analysis of
           Fibre Materials: Scope and Challenges
    • Abstract: Two instrumental test methods—FibreShape flatbed scanning and Dia-Stron laser diffraction technology—are used for diameter analysis of lignocellulosic hollow fibrous material produced from biomass of two different canola cultivars, 5440 and 45H29. Although FibreShape is capable of working with any size of dataset, a larger dataset would generate the optimum analytical test results. Interestingly, FibreShape operates faster and saves time. On the contrary, Dia-Stron is restricted to data size, due to the limitation of its cassette slots for specimen storage. Further, this machine is slow in processing—which takes hours to complete—and the presence of microscopic cracks on the fibre surface will generate erratic test results for that specific fibre, which, however, is not notified by the computing system until the test-run is completed for all the loaded fibres. Such a practice might become challenging due to research time constraints. The requirement of consistent gauge length is another limitation of this laser diffraction test method to test staple fibres and filaments unlike the FibreShape. Upon testing the 45H29 cultivars, FibreShape and Dia-Stron exhibited a smaller difference of 12 µm (= 88.26 − 76.26) in fibre diameters between their test results, whereas the difference was as large as 44.6 µm (= 120.29 − 75.69) for the 5440 fibres. However, the statistical t-test did not identify any significant variation between the observed test results obtained from FibreShape and Dia-Stron as p = 0.34 > α = 0.05 (95% confidence interval). The current study favours using FibreShape over Dia-Stron for analysing textile fibre diameters due to the versatility of working capacity with any specimen shape or configuration, size of a dataset, speed of conducting a test, flexibility of sample selection and preparatory processes, and gauge-length independence.

  • Enhancement of Thermo-mechanical Properties of Okra Fiber by Photografting
    • Abstract: In this study, okra fibers were chemically modified with three different monomers such as ethylene glycol dimethacrylate (EGDMA), 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) solutions in the presence of methanol (MeOH) and photoinitiator (Irgacure-500) under ultraviolet (UV) radiation with a view to improve thermo-mechanical characteristics. Based on grafting efficiency and mechanical attributes the intensity of UV radiation and monomer concentration were maximized. A series of solutions by varying the concentrations (10–70%) of monomers in MeOH along with 2% photoinitiator were prepared. Experimental results revealed that fibers grafted with 30% EGDMA at 30th pass, 30% HEMA at 20th pass and 40% MMA at 30th pass of UV radiation achieved optimum mechanical properties over untreated fiber. The optimized solutions were further enhanced by adding various concentrations (1–2%) of urea, and the best properties were obtained with 1.5% urea-treated fiber. The chemical bonds formed due to photografting were inspected by Fourier transform infrared spectroscopy (FTIR). Degradation behavior under heat was performed through thermogravimetric analysis (TGA/DTG) and found that photografted fiber showed well-improved thermal stability than the untreated sample. Water uptake test exhibited that grafting reduced water retention capacity of treated fiber significantly. Furthermore, simulating weathering test also executed.

  • Water Absorption, Thermal and Microstructural Properties of Plastic
           Composites Developed from Isoberlinia Doka Wood Sawdust and Polystyrene
    • Abstract: In this study, the water absorption, thermal conductivity and microstructural properties of Isoberlinia doka wood sawdust polystyrene composite, synthesised by the hand layup method, were investigated as a function of filler content. It was observed that the thermal conductivity increased with increase in the fibre loading. The thermal conductivity value obtained for the synthesised composite samples was an average of 0.147 Wm−1 k−1. The composites absorbed water until equilibrium was achieved on the 9th day. The maximum water absorbed at equilibrium for the composite with filler concentration of 10, 20, 30 and 40 wt% was 36.46, 40.34, 57.53, 128.65 wt%, respectively. The mass transfer kinetics revealed that water sorption rate increased at higher filler composition due to the increased interstitial pores and gaps that are exacerbated by increased fibre loading. The mass transfer kinetic constants for the composite with filler concentration of 10, 20, 30 and 40 wt% were 0.738, 0.661, 0.996 and 1.155 day−1. Microstructural analysis revealed that the dispersion of wood sawdust particles improved as the fibre loading increased.

  • Separation and Recovery of 4-Hydroxybenzoic Acid Using Molecular
           Imprinting Technique from Dilute Solution
    • Abstract: Fruits and vegetable waste (FVW) have been reported to have micronutrient and bioactive compound like polyphenol albeit in very small quantity (μg g−1). The challenge of selective separation and recovery of one of the polyphenols from dilute solution is addressed in the present work using molecular imprinting technique, which uses molecularly imprinted polymers (MIPs). This study focuses on the extraction of a high value bioactive compound [P-Hydroxybenzoic acid (PHBA)] which is present in FVW. Chitosan-based PHBA imprinted polymer was synthesized using PHBA as template and TEOS as cross-linker to achieve the above goal. MIP was characterized using SEM, EDAX and FTIR. Batch adsorption studies were conducted to optimize the adsorbent dose, initial concentration, and contact time. Two-parameter isotherm models namely Langmuir, Freundlich, Temkin and Dubinin–Radushkevich and three-parameter isotherm model Sips was used to analyze the experimental data. The equilibrium data fitted best into Langmuir isotherms model with capacity of 74.56 mg g −1 and followed pseudo-second-order kinetic model. The reusability confirmed that MIP retained its adsorption capacity up to 6 cycles.

  • Study and Fabrication on Heat Efficient Stove of Low Smoke Emission
    • Abstract: This work addresses the rural-based chulha (stove) fabrication with less smoke emission. Many traditional cooking techniques used in Indian villages are inappropriate and cause environmental and health hazards like respiratory and vision problems as well as monetary loss. The main objective of this work is to design a stove that overcomes these problems. Emphasis has been made to increase the thermal efficiency of the stove and reduce smoke emission. Here, the focus is to incorporate proper supply of air to the burning chamber for clean burning and ensure primary and secondary combustion. Air is supplied for two purposes; these are primary and secondary combustion. Primary combustion is held in the fuel holder where fuel is burnt by the direct supply of preheated air. Secondary combustion takes place at the top of the burning chamber by burning the smoke that is produced during the primary combustion. This results in reduction of smoke and also ensures clean burning of the fuel. Moreover, refractory materials have also been used to reduce the heat loss. The materials utilized for building this model are locally available and these are low cost. The experiment has been carried out in three stages in terms of each prototype model where the modification is done on the predecessor. The effort has been made to maintain a proper balance between the efficiency of the stove and the low smoke production tendency of the stove. Experiments have been performed in each of the prototype for finding the thermal efficiency.

  • Smartphone-Assisted Detection of Chlorine Concentration in Water Samples
           Using a Microfluidic Chip
    • Abstract: Chlorine is a strong oxidizing agent, aids in killing viruses and bacteria present in the water. The presence of free chlorine in the water eliminates the presence of pathogens and ensures safe drinking water. Meanwhile, residual free chlorine in the water if consumed in excess will lead to various health problems including cancer. World Health Organization has given out suggestions for the safe usage of chlorine in the water treatment. Adequate controlling and monitoring the amount of the chlorine present in the water is crucial for domestic as well as industrial use of water. Various commercial systems are available in the market for chlorine analysis. But these systems are bulky and very expensive. Herein a simple low-cost portable smartphone device is introduced which can be used for the rapid determination of free chlorine content in water. The proposed model relies on the colorimetric action of DPD reagent followed by data processing using the sensing system. The sensing system consists of a smartphone camera as a detector, which captures images and processes data with the help of a smartphone application. The software app is developed to use with the phone for recording and analyzing the RGBA value of the color of the image captured. The portability of the designed system was ensured by using a casing assembly designed using additive manufacturing procedures. The linear range of residual free chlorine estimation is 0–10 ppm with a sensitivity of measurement of 0.02 ppm was confirmed with known chlorine concentration samples as well as blind testing.

  • Development of Antimicrobial and Wound Healing Properties on Cotton
           Medical Bandage by using the Extract of Eco-Friendly Herbs
    • Abstract: The purpose of the study is to produce herbal medical bandages which have antimicrobial properties as well as which will heal the wound place without applying any dressing materials. In this purpose, extracts of two eco-friendly herbs Bikash leaf (Mikania micrantha) and Durba grass (Cynodon dactylon) were used. After the sample preparation, odor test, antimicrobial activity and FTIR analysis were done. To justify healing properties, implementations of the samples were done on the wound place of a rabbit with the permission of local veterinary department. Both the herbs showed excellent results upon odor test and got rating 2 (weak odor) according to odor rating scale. In case of antibacterial activity, samples padded with C. dactylon possessed zone of inhibition (ZOI) of 11mm and 20 mm whereas M. micrantha padded samples possessed ZOI of 10 mm and 19 mm against Gram-negative and Gram-positive bacteria, respectively. The FTIR result confirmed the presence of phytochemicals on both herbal-treated fabrics. Results of wound healing were also satisfactory. After five days, the bandages were opened up and the place was healed completely. There are large demands on eco-friendly products in medical fields. So, these treated samples can be used as medical bandages in commercial basis.
