Nanoparticles with controlled size and composition are of fundamental and technological interest as they provide solutions to technological and environmental challenges in the areas of catalysis, medicine, solar energy conversion and water treatment. Thus, production and application of nanomaterials is an emerging fie…
he field of polymer composites is a rapidly developing area of study in materials science. The addition of a variety of new component materials, such as carbon fibers, clay, carbon nanotubes, nanocrystalline cellulose, etc., to polymeric matrices is designed to enhance properties and add value to the end-use product.…
The study was designed to isolate and characterize the collagen from skin, scales and fins of Cyprinus carpio and Hypophthalmichthys molitrix . For this purpose nine fishes of each species of three weight groups were collected and categorized as W1 (250-500 g), W2 (501-750 g) and W3 (751- 1000 g). The maximum skin pro…
Dextran Coated Ferrite Nanomaterials (DFNM) of size <25 nm was synthesized, characterized and the acute oral toxicity along with antioxidant enzymes activities were evaluated in Wistar rats. The healthy adult rats were orally administered with 300 and 2000 mg/kg body weight of DFNM using a gastric needle and observed…
TMPTA prepolymer resin and photoinitiators of ITX/TPO had been encapsulated in core-shell structured microcapsules as optical responding ingredients based on interfacial polycondensation method, and polyurea structured microcapsule shell had been formed on the sheared O/W interface. The synthesized microcapsule had re…
Prolongation of vase life of cut lilies (Lilium orientalis cv. ‘Shocking’) was studied in vase containing 5, 15, 25, 35 ppm of nano-silver solutions and deionised water as control under controlled conditions. All nano-silver treatments extended the longevity of cut flowers in comparison to control but the concentratio…
In this work, at room-temperature and without any organic surfactants we reported two green and facile approaches for rapid synthesis of ZnO nanorods (NRs) and nanosheet-based ZnO hierarchical structures (NSHSs). Based on their structural advantages, the quasi-solid ZnO-DSCs achieved a record photoelectric conversion…
High-surface-area crystalline mesoporous tantalum oxide has been successfully synthesized using a pluronic tri-block polymer as the template.
In the present work, the effective thermal conductivity of teak wood dust (TWD) filled epoxy composites at different volume fractions (6.5, 11.3, 26.8 and 35.9%) have been determined experimentally by using Lee’s Apparatus. Composites of teak wood dust particles of 150µ, 200µ and 250µ sizes with varying volume fractio…
The enzyme tyrosinase could trigger the disassembly of peptide-based nanospheres, resulting in F-NMR signal turning on.
Al2O3–C sensor based on the blackbody cavity theory achieved a continuous measurement of molten steel temperature. Its mechanical properties were affected by the firing temperature. Firing temperature has great influences on the weight changing, decalescence/heat release reaction and structure evolution of the resin b…
Chiral three-dimensional Mg( <sc>ii</sc> ) and Mn( <sc>ii</sc> ) sulfates have been synthesized, well characterized and studied from first-principles calculations. High temperature X-ray diffraction, thermogravimetric analysis and DFT calculations reveal that the structures of both the compounds remain intact even aft…
The reaction pathways for H2 release from cyclic amine–alane adducts in the presence and absence of alane (AlH3) are investigated and the associated potential energy surfaces are constructed by employing the composite G4MP2 method. The computed Gibbs free energy change values are potential proof of the thermodynamic f…
Athi River bentonite clay was activated using sulphuric acid at various acid concentrations, clayacid ratio, temperature and contact times. Optimization was based on palm oil bleaching performance. The chemical compositions of the raw clay and clay activated at different acid concentrations were analysed to investigat…
Flexibility in natural gas combined cycle power plants (NGCC) with pre-combustion CO 2 capture could be introduced with co-production of hydrogen and subsequent hydrogen storage with metal hydrides (MH). The current work presents a thermodynamic analysis and comparison between steady state ASPEN Plus models of a refer…
The mechanical properties of polyglycolic acid (PGA) of different water weight fractions (1.7%, 2.9%, and 5%) were investigated by molecular dynamics (MD) simulation through a tensile test.
In this study one commercially available hip impact protective garment was evaluated in terms of thermo-physiological wear comfort, namely Dry Thermal Resistance, Evaporative Resistance and Permeability Index. Objective evaluation of thermal characteristic of this hip impact protective garment is carried out by means…
A tetraradical-containing octanuclear vanadium cluster (V8, complex 2) was synthesized by reacting N(2-methoxyanilino)-3,5-di-tert-butylphenol and VOSO4·5H2O in the presence of Et3N in MeOH. The reaction proceeded via a ligand centre C–N bond cleavage and C–O bond formation. The V8 cluster was comprised of two identic…
The aim of this study is to evaluate, prepare, and characterize bioactivity of chitosan microspheres loaded with bFGF for providing sustained release of bFGF. Porous chitosan microspheres were prepared by freeze‐drying process based on the interaction between chitosan and tripolyphosphate (TPP). The bFGF‐loaded chitos…
These studies show covalent attachment of multilayers (CAM) to chemically alter surfaces to achieve pH switchable antimicrobial and anticoagulant properties. Polyethylene (PE), poly(tetrafluoroethylene) (PTFE), and silicon (Si) surfaces were functionalized by tethering pH-responsive “switching” polyelectrolytes consis…
