Biological assessment is a useful alternative for assessing the ecological quality of aquatic ecosystems since biological communities integrate the environmental effects of water chemistry. Algal and water samples werecollected at monthly intervals from three sites of River Mutha (Pune, India). The most pollution tole…
Porous nanocrystalline ZnGa2O4 catalysts were synthesized by a simple soft-chemical method at low temperature. The catalysts were characterized by XRD, nitrogen adsorption, SEM, TEM, UV/ vis, and FT-IR spectroscopy. The activity of the photocatalysts was evaluated by decomposition of benzene and its derivatives in the…
A novel hyperbranched azo-polymer was prepared by a ruthenium-based catalyst RuCl 2 (PCy 3 )(SIMes)(CHPh) using acyclic diene metathesis (ADMET) polymerization of an AB 2 monomer, 4-undecylenyloxycarbonyl-4′-[bis(2-ethyl acrylate)amino]azobenzene, which was synthesized from the esterification reaction between N,N -bis…
Oxadiamondoids representing a new class of carbon nanoparticles were prepared from the respective diamondoid ketones via an effective two-step procedure involving addition of methyl magnesium iodide and oxidation with trifluoroperacetic acid in trifluoroacetic acid. The reactivities of the oxacages are determined by t…
Abstract Alanates, borohydrides, and amides are complex hydrides with high concentration hydrogen that have been actively investigated for materials‐based hydrogen storage on‐board polymer electrolyte membrane fuel cell (PEMFC) vehicle applications. The major challenge is to release hydrogen at fuel cell working tempe…
Abstract Synthesis, photophysical, and electrochemical characterizations of iridium‐complex anchored polyhedral oligomeric silsesquioxane (POSS) macromolecules are reported. Monochromatic organic light‐emitting devices based on these phosphorescent POSS materials show peak external quantum efficiencies in the range of…
A matter of technique: For a new steroidal lactol, jaborosalactol 24 (1), isolated from Jaborosa parviflora, NMR spectroscopy residual dipolar couplings and powder X-ray diffraction analysis independently gave the same stereochemistry at C23–C26. Conventional NMR spectroscopic techniques, such as NOE and 3J coupling-c…
Photovoltaic (PV) devices based on CdSe/CdTe-C60 active layers, in which the nanocrystal and fullerene (C60) layers work as electron-donor and electron-acceptor/transport layers, respectively, were fabricated. Efficiencies up to 0.62% were reached in the hybrid cells. The PV performance was greatly improved with respe…
A component of the compressive stress that develops during deposition of polycrystalline thin films reversibly changes during interruptions of growth. The mechanism responsible for this phenomenon has been the subject of much recent speculation and experimental work. In this Letter, we have varied the in-plane grain s…
The interaction of water with fabrics, which incorporates water vapor permeability, wicking abilities and drying behaviors of the fabrics, are tested to obtain some comfort-related properties of fabrics from cotton, acrylic and cotton—acrylic blends. The effects of categorical variables such as fiber composition, yarn…
A pseudospin model of a multiferroic system which exhibits both relaxor ferroelectric and relaxor ferromagnetic behavior is presented. The electric and magnetic degrees of freedom associated with the simultaneous presence of polar nanoregions and magnetic nanoregions are described by two sets of pseudospin variables,…
Squaraine nanowires self-organize into a well-ordered film through a simple solvent-evaporation process at the dichloromethane/water interface. The film can be transferred onto various substrates or stacked layer-by-layer into a multilayered structure. This one-step approach offers a low-cost method for producing scal…
Novel chiral AIE compounds bearing a tartaric acid group were synthesized. They selectively aggregated with one enantiomer of a number of chiral amines, such that one enantiomer led to strong fluorescence and another enantiomer showed no or only weak fluorescence. This was used for the quantitative analysis of enantio…
Nanocrystalline phase pure CeCrO 3 was synthesized by a two-step synthesis. The compound was investigated by a host of characterization techniques such as X-ray diffraction, high-temperature X-ray diffraction, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric−differe…
In this study, thermal properties of different cotton and Angora rabbit fiber blended fabrics were investigated. It is known that cotton fiber has good comfort properties and Angora rabbit fiber is a speciality fur fiber which possesses good softness, whiteness and warmth. The aim of this study was to combine the exce…
An explicit connection between the electronic structure and the anisotropic high conductivity of delafossite-type PdCoO2 has been established by angle-resolved photoemission spectroscopy (ARPES) and core-level x-ray photoemission spectroscopy. The ARPES spectra show that a large hexagonal electronlike Fermi surface (F…
Fine polythiophene (PTh) microparticles were successfully synthesized by a novel interfacial polymerization at a dynamic interface between two immiscible solvents, i.e., n-hexane and acetonitrile or nitromethane containing thiophene and oxidant, respectively. The polymerization yield, size, and electrical conductivity…
Abstract Two series of biodegradable polymer blends were prepared from combinations of poly( L ‐lactide) (PLLA) with poly(ϵ‐caprolactone) (PCL) and poly(butylene succinate‐ co ‐ L ‐lactate) (PBSL) in proportions of 100/0, 90/10, 80/20, and 70/30 (based on the weight percentage). Their mechanical properties were invest…
Adhesion research has made use of surface analysis since the mid-1970s, but by the end of that decade there were, perhaps, only two or three research groups worldwide that had a strong presence in both adhesion and surface analysis. By the end of the following decade, the situation had changed signi cantly and surface…
Abstract Natural leather is processed from hides and skins of animals. Synthetic leathers are becoming popular as an alternative material owing to limited availability and varying size of natural leathers. There is a need to understand the properties of natural and synthetic leathers to select proper material for an a…
