Article
A new microwave plasma assisted sol‐gel (MPAS) technique was adopted to produce Titanium dioxide (TiO2) photocatalyst by using pure and mixed stabilizers. The crystalline phases, composition, bandgap energy and surface morphology of TiO2 were studied through SEM, XRD, FT‐IR, UV‐Visible spectroscopy and photoluminescence spectroscopy. The average pa...
Article
An ultrasonication approach was adopted for Azadirachta indica driven bioconversion of silver salt into silver nanoparticle (AgNPs). These nanoparticles were coated over plasma functionalized cotton by using a pad dry cure technique. For pre‐coat surface functionalization, the cotton fabric was exposed to an open air single dielectric barrier disch...
Article
Thermophysical analysis of the crustal rocks is important for heat transfer determination and insulation purposes to save energy in buildings. In the presented work, thermophysical properties of four limestones were investigated in dry and moist state under ambient conditions by using a transient plane source method. A thermal constant analyzer was...
Article
The recycling of chemical containing glass bottles is generally not recommended due to high health risk. In this study, used glass ampoules were devitrified into a porous material by coprocessing with eggshells, salt, and soda at different temperatures. In this thermochemical reaction, eggshells decomposed into calcium, porogenic gases, and char. T...

The present work is focused on the development of an effective process for the conversion of waste soap into fuel oil and gas. The waste soap was converted into highly combustible gas and oil by using low-cost white cement and burnt brick powder catalysts. Optimum conditions for both catalytic and non-catalytic pyrolysis were investigated by varyin...
Article
Polystyrene is a nondegradable lightweight foamy substance that easily blows from landfills into drains and waterways. This material creates litter and water pollution and harms the wildlife who mistakenly eat it. This study investigated a cost‐effective pyrolysis approach for catalytic conversion of waste polystyrene into useful oil and gas produc...
Article
Waste polyethylene is one of the most abundant plastics coming to the municipal waste. Polyethylene releases toxic chemicals, which deteriorate the environment and human health. This study investigates the valorization of waste polyethylene through thermal and thermo-catalytic pyrolysis process. Being low cost and reusable, the ordinary Portland an...
Article
The objective of the presented work was to convert waste glass and mollusk shells into a porous material for separation of the direct blue 15 azo dye from industrial wastewater. The porous glass material of specific pore size and surface area was prepared through a thermochemical reaction by reacting waste glass with mollusk shells, soda, and rock...

Super-resolution microscopies have become an established tool in biological research. However, imaging throughput remains a main bottleneck in acquiring large datasets required for quantitative biology. Here we describe multifocal flat illumination for field-independent imaging (mfFIFI). By integrating mfFIFI into an instant structured illumination...
Article
Optical flat-fielding systems, such as field-mapping or integration-based beam shapers, are used to transform nonuniform illumination into uniform illumination. Thus, flat-fielding paves the way for imaging that is independent of position within a field of view and enables more quantitative analysis. Here, we characterize and compare three systems...

The world does not have too much time to ensure that the fast-growing population has enough land, food, water and energy. The rising food demand has brought a positive surge in fertilizers’ demand and agriculture-based economy. The world is using 170 million tons of fertilizer every year for food, fuel, fiber, and feed. The nitrogenous fertilizers...
Article
Fluidized bed technology is being used in several industrial processes. The well-controlled fluidization of a bed material is a prerequisite for successful implementation of this technology. Several variants of distributors are being tested for fluidized beds; however, scant information is available on their working regimes. In this study, an annul...

Super-resolution microscopies, which allow features below the diffraction limit to be resolved, have become an established tool in biological research. However, imaging throughput remains a major bottleneck in using them for quantitative biology, which requires large datasets to overcome the noise of the imaging itself and to capture the variabilit...

Carbon dioxide is one of the major greenhouse gases and a leading source of global warming. Several adsorbent materials are being tested for removal of carbon dioxide (CO2) from the atmosphere. The use of multiwalled carbon nanotubes (MWCNTs) as a CO2 adsorbent material is a relatively new research avenue. In this study, Fe2O3/Al2O3 composite catal...

High fertilizer inputs augment the reactive nitrogen level in soil, air, and water. Unused reactive nitrogen acts as a pollutant and harms natural resources. This study focused on the thermal processing of corn starch into a coating material using disodium tetraborate and urea. The processed corn starch was coated over granular urea in a vertical b...

In this study, multiwalled CNT bundles were synthesized with an alumina-supported Fe 2 O 3 catalyst by using a floating catalyst chemical vapor deposition (FCCVD) technique. The metal catalyst was synthesized by dispersing Fe 2 O 3 on alumina support. Ethylene molecules were decomposed over different amounts of metal nanoparticles in a FCCVD reacto...
Article
In this study, water hyacinth was converted into highly flammable bio-oil via two-step catalytic pyrolysis. The upgradation of bio-oil was based on the pretreatment of biomass, second-step pyrolysis and use of clinkered material as a catalyst. This three-prong approach was found effective for improving the nature and yield of the oil by lowering th...
Article
In this study, water hyacinth was converted into highly flammable bio-oil through a two-step catalytic pyrolysis approach. A three-prong approach, based on biochemical pre-treatment of the biomass, use of clinkered catalyst and an additional pyrolysis step, was adopted to produce highly upgraded bio-oils. Fresh, putrefied and microbe treated water...
