Abstract It is still challenging to develop new and low‐cost proton‐conductive solid electrolytes using a simple synthetic procedure. Herein, a new proton‐conducting material was synthesized for the first time through a sol‐gel method by merging niobium oxyhydroxide with polyoxometalate (POM). NbO 2 (OH)‐PW 12 exhibit…
The transition metal oxide has been recognized as one of the promising electrode materials for electrochemical capacitor application. Due to the participation of charge transfer reactions, the capacitance offered by transition metal oxide can be higher compared to double layer capacitance. The investigation on hydrous…
Niobium pentoxide (Nb 2 O 5 ), also known as niobia, has been applied in several areas among others in heterogeneous catalysis. This is due to both its high acidity (Brönsted acid and Lewis acid sites) and its Lewis acid sites tolerant to water. The structure and morphology of these sites present tunable quantity and…
NOx emission is produced during combustion of fuels at high temperature. Excessive release of NOx causes several effects on living organisms and environment. In this work, the efforts to reduce NOx emission by developing electrochemically activated cells (EACs) for a diesel engine fuelled with diesel and biodiesel fue…
Sulfonated cellulose beads were prepared by oxidation of Cladophora nanocellulose to 2,3-dialdehyde cellulose followed by sulfonation using bisulfite. The physicochemical properties of the sulfonated beads, i.e., high surface area, high degree of oxidation, spherical shape, and the possibility of tailoring the porosit…
Abstract NiAl 2 O 4 ‐based materials are known as enhanced catalysts for several catalytic applications that have coke deposition in common. In this study, Nb as a dopant was found to occupy the octahedral sites of the spinel preferably. As a result, the cation distribution was altered between the two sub‐lattices of…
The present investigation was undertaken to evaluate the genotoxic effect of zinc nanoparticles (ZnNPs) synthesized by leaf extract of Albizia saman on mitotic chromosomes of root tip meristematic cells of Drimia indica. Biogenic ZnNPs were characterized by using UV-vis spectroscopy, Fourier transform infrared spectro…
A series of lithium metal selenites, Li 6 M(SeO 3 ) 4 (M = Co, Ni, and Cd) and Li 2 Zn(SeO 3 ) 2, were synthesized by hydrothermal and solid-state reactions. Li 6 M(SeO 3 ) 4 is composed of Li + cations, MO 6 octahedra, and SeO 3 polyhedra, while Li 2 Zn(SeO 3 ) 2 consists of Li +, Zn(Li)O 4 tetrahedra, and SeO 3 poly…
Summary Two kinds of carbon and phosphorus synergistic system used to improve the flame retardancy of rigid polyurethane foams (RPUF) were studied. One is the synergistic effect of expandable graphite and guanidinium phosphate; the other is red phosphorus and guanidinium phosphate. The flame retardant properties and m…
The following organic and organic–inorganic hybrid compounds were prepared as photo-luminescent materials following efficient and practical synthetic methods: 1,3-bis[4-(n-alkoxy)phenyl]-2-propen-1-one (where, n-alkoxy: O(CH2)nH, n = 6,7,8,9 or 10); 3,5-bis[4-(n-alkoxy)phenyl]-1H-pyrazole (where, n-alkoxy: O(CH2)nH, n…
The object of this study is to investigate the flexural properties of biocomposites based on polypropylene/kenaf fiber/polypropylene-grafted maleic anhydride (PP/kenaf/PP-g-MA) using the response surface methodology. A three-factor, three-level Box–Behnken design, which is the subset of the response surface methodolog…
Abstract Quantum dot (QD) light‐emitting diodes have been intensively investigated as a future display technology owing to their outstanding optoelectronic properties such as narrow spectral bandwidths and high quantum efficiencies. Significant efforts have been made to achieve full color QD light‐emitting diodes (QLE…
PURPOSE: Sepantronium bromide (YM155) is a hydrophilic quaternary compound that cannot be administered orally due to its low oral bioavailability; it is furthermore rapidly eliminated via the kidneys. The current study aims at improving the pharmacokinetic profile of YM155 by its formulation in immunoliposomes that ca…
Resilin functions as an elastic spring that demonstrates extraordinary extensibility and elasticity. Here we use combined techniques, laser scanning confocal microscopy (LSCM) and scanning electron microscopy (SEM) to illuminate the structure and study the function of wing flexibility in damselflies, focusing on the g…
In this work, the effect of the addition of boron nitride (BN) fillers in a thiol-cycloaliphatic epoxy formulation has been investigated. Calorimetric studies put into evidence that the kinetics of the curing has been scarcely affected and that the addition of particles does not affect the final structure of the netwo…
The structural arrangement of alkali-modified calcium aluminosilicate glasses has implications for important properties of these glasses in a wide range of industrial applications. The roles of sodium and potassium and their competition with calcium as network modifiers in peralkaline aluminosilicate glasses have been…
Novel selective ceramic-supported thin polyimide films produced in a single dip coating step are proposed for membrane applications at elevated temperatures. Layers of the polyimides P84®, Matrimid 5218®, and 6FDA-6FpDA were successfully deposited onto porous alumina supports. In order to tackle the poor compatibility…
Pursuit of materials with desirable mechanical properties is an eternal theme. The reported BC 2 N exhibiting high hardness and superior stability is deemed as the potential alternative to diamond. However, its crystal structure has not been unambiguously determined thus far. Here, we identify a hitherto unknown R 3 m…
Crystals of the heterocyclic radical naphtho-1,3,2-dithiazolyl NDTA display magnetic bistability with a well-defined hysteretic phase transition at T c ↓ = 128(2) K and T c ↑ = 188(2) K. The magnetic signature arises from a radical/dimer interconversion involving one of the two independent π-radicals in the P 1̅ unit…
Various physical phenomena have been used to develop variable-stiffness (VS) materials and structures, but all have involved some elements of manual fabrication, which limits their applications. In contrast, here we show fully three-dimensional (3D) printed monolithic VS structures that can be used directly from the p…
