Valorization and optimization of agro-industrial orange waste for the production of enzyme by halophilic Streptomyces sp.
( Academic Press Inc. , 2021 , Article)This study underlines the biotechnical valorization of the accumulated and unusable remains of agro-industrial orange fruit peel waste to produce α-amylase under submerged conditions by Streptomyces sp. KP314280 (20r). The ... -
Valorization of biodiesel byproduct glycerol to glycerol carbonate using highly reusable apatite-like catalyst derived from waste Gastropoda Mollusca
( Springer Science and Business Media Deutschland GmbH , 2020 , Article)Predominantly, calcium oxide from the calcined waste Gastropoda Mollusca (Achatina fulica sp.) was post-functionalized and stabilized using trisodium phosphate to obtain an apatite-like catalyst (snail shell apatite, SNS-AP) ... -
Variance-based global sensitivity analysis of a multi-population, single-chamber microbial fuel cell operating in continuous flow mode at steady state
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)Microbial fuel cells (MFCs) are environmentally friendly devices which are used to convert chemical energy in organic wastes to electrical energy. MFCs have a strong non-linearity that requires a very sophisticated controlling ... -
Various potential techniques to reduce the water footprint of microalgal biomass production for biofuel—A review
( Elsevier B.V. , 2020 , Other)Due to their rapid growth rates, high lipid productivity, and ability to synthesize value-added products, microalgae are considered as the potential biofuel feedstocks. However, among the several bottlenecks that are ... -
Virtual mimic of lab experiment using the computer-based Aspen Plus® Sensitivity Analysis Tool to boost the attainment of experiment's learning outcomes and mitigate potential pandemic confinements
( John Wiley and Sons Inc , 2022 , Article)The computer-based Aspen Plus® Sensitivity Analysis Tool (APSAT) was used as a virtual environment to mimic a gas absorption lab experiment in the Unit Operations Lab within the curriculum for the Bachelor of Science in ... -
Viscosity and density of ternary solution of calcium chloride + sodium chloride + water from T = (293.15 to 323.15) K
( American Chemical Society , 2014 , Article)Viscosities and densities of ternary systems of CaCl2–NaCl–water were measured in the range of T = (293.15 to 323.15) K at 5 K intervals and up to 4.5 mol·kg–1. Two equations based on the Exponential and Goldsack and ... -
Viscous behavior of imidazolium-based ionic liquids
(2013 , Article)The viscosity of four imidazolium-based ionic liquids is analyzed as a function of pressure and temperature. Experimental measurements were carried out using an electromagnetic moving piston viscometer in the 303-353 K and ... -
Viscous origin of ionic liquids at the molecular level: A quantum chemical insight
( Elsevier , 2014 , Article)The viscosity of selected families of ionic liquids has been assessed at the molecular level as a function of the intermolecular interactions using Density Functional Theory together with Atoms-in-a-Molecule and Natural ... -
Viscous-Gravity spreading of oil on water
( John Wiley & Sons, Inc. , 2001 , Article)Spreading of oil on calm water is analyzed for the second stage of spread, which is controlled by a balance between gravity and viscous forces. The analysis, using the integral boundary-layer method, agreed well with a ... -
Visible light-driven metal-oxide photocatalytic CO2 conversion
( John Wiley & Sons, Ltd. , 2015 , Article)In this work, nine photocatalysts were prepared by a conventional solid-state reaction method. The samples were characterized by X-ray diffraction, UV–Vis diffuse reflectance spectroscopy, surface area measurements based ... -
Weakly Conjugated Hybrid Zinc Porphyrin Sensitizers for Solid-State Dye-Sensitized Solar Cells
( Wiley-VCH Verlag , 2016 , Article)Molecularly engineered weakly conjugated hybrid porphyrin systems are presented as efficient sensitizers for solid-state dye-sensitized solar cells. By incorporating the quinolizino acridine and triazatruxene based unit ... -
What Happens Without Nickel? Cyclization Reactions of Ethylene with Ethanedithial and Related Molecules
( John Wiley and Sons Inc. , 2018 , Article)We present a computational study of the mechanism of the formation of 6-member heterocycles through the binding of ethylene to oxaldehyde, ethanedithial, and 2-thioxoacetaldehyde. This process is related to the olefin ... -
When bioelectrochemical systems meet forward osmosis: Accomplishing wastewater treatment and reuse through synergy
( MDPI AG , 2015 , Other)Bioelectrochemical systems (BES) and forward osmosis (FO) are two emerging technologies with great potential for energy-efficient water/wastewater treatment. BES takes advantage of microbial interaction with a solid electron ... -
Zeolitic imidazolate framework (ZIF-8) based polymer nanocomposite membranes for gas separation
( Royal Society of Chemistry , 2012 , Article)As synthesised ZIF-8 nanoparticles (size ∼ 60 nm and specific surface area ∼ 1300–1600 m2 g−1) were directly incorporated into a model polymer matrix (Matrimid® 5218) by solution mixing. This produces flexible transparent ... -
