Aligned electrospun poly(ethylene terephthalate) (ePET) nanofiber mats have been fabricated, which mimic the media layer of arteries. We used three different plasma etching techniques to bring their mechanical and surface properties in line with those of natural blood vessels: (i) atmospheric pressure (“HP”) corona di…
Mesoporous NiCu–CeO 2 oxide catalysts were synthesized by using the evaporation-induced self-assembly method applied to the high-temperature, water–gas shift reaction (HT-WGS) between 350 to 550 °C.
The photocatalytic degradation of methylene blue (MB) dye in aqueous solution was investigated using hexagonal molybdenum oxide (h-MoO3) nanocrystals under visible light irradiation. Chemical precipitation method was utilized to synthesize h-MoO3 and control over the crystal size, shape and distribution were character…
Photobleaching is a widespread problem in any optical study or application involving fluorophores and is particularly acute in the context of single-molecule detection. Fluorophores adsorbed on metallic nanostructures are not immune to this problem, but little effort has been devoted to understanding how photobleachin…
High velocity oxygen‐fuel (HVOF) thermal spraying was used to fabricate Al and metal matrix composite (Al/SiCp) coatings on the Mg alloy AZ91 surface in order to investigate their efficacy as corrosion‐control coatings. The corrosion behaviour of the coated specimens was evaluated by electrochemical methods and Taguch…
Magnesium complexes based on N , N -bidentate phenanthrene derivatives derived from Schiff bases were synthesized and investigated as catalysts for rac -lactide polymerization.
The popular bar prank known in colloquial English as beer tapping consists in hitting the top of a beer bottle with a solid object, usually another bottle, to trigger the foaming over of the former within a few seconds. Despite the trick being known for a long time, to the best of our knowledge, the phenomenon still l…
Poloxamer finds excellent clinical and therapeutic uses for curing of various ailments. The Zin- giber officinale (Z. officinale) is one of the well-known medicinal plants. The poloxamer188 and the rhizome extract of Z. officinale have been used to synthesize the gold nanoparticles (AuNPs) by a green approach. The Z.…
Highly textured tin(II) sulfide thin films are prepared from a nanocrystal ink comprised of high-aspect-ratio nanosheets. The orthorhombic nanosheets are synthesized colloidally to isolate lateral growth and minimize the presence of alternate crystal phases. The tin sulfide films deposited from the nanosheets exhibit…
The fluorescence enhancement effect of covalently fixed fluorescent chromophores has been investigated by means of kinetic analysis of decay rate constants and theoretical calculations. Derivatives of 1-cyano-1,2-diphenylethene dimer have a distorted cyclic structure when both ends are clipped with two naphthalene-1,8…
The charge carrier transport in carbon nanotubes is highly sensitive to certain molecules attached to their surface. This property has generated interest for their application in sensing gases, chemicals and biomolecules. With over a decade of research, a clearer picture of the interactions between the carbon nanotube…
The structural, vibrational, electronic, and dynamic properties of amorphous and liquid AsxSe1-x (0.10 <x < 0.45) are studied by First Principles Molecular Dynamics. Within the above range of compositions, thresholds, and anomalies are found in the behavior of reciprocal and real space properties that can be correlate…
Two novel isomorphic borates, Q18Mg6(B5O10)3(B7O14)2F (Q = Rb and Cs), were synthesized from high-temperature solutions. These borates are created from two kinds of isolated polyborate anionic groups, [B5O10] and [B7O14], and are further examples of two kinds of isolated polyborate anions coexisting in one borate stru…
The interfacial atomic structure of a metallic ${\mathrm{LaNiO}}_{3}/{\mathrm{LaAlO}}_{3}$ superlattice grown on a ${\mathrm{LaSrAlO}}_{4}$ substrate was investigated using a combination of atomically resolved electron energy loss spectroscopy (EELS) at the Al $K$, Al ${L}_{2,3}$, Sr ${L}_{2,3}$, Ni ${L}_{2,3}$, La ${…
We present a comprehensive comparison of electrical properties of differently fabricated high quality Schottky contacts on ZnO thin films grown by pulsed laser deposition. Thermally evaporated Pd/ZnO Schottky contacts exhibit ideality factors as low as 1.06 due to their high lateral homogeneity. The effective Richards…
BACKGROUND: Gelatin has long been widely used in foods, pharmaceuticals, cosmetics, and other products. However, there are few reports on its bioavailability and bioavailable forms. In this study, the bioavailability of gelatin was indirectly evaluated by the determining the bioavailability of total hydroxyproline in…
Two nanosized fillers (fumed silica Rosil-175 up to 20 wt% and halloysite nanotubes up to 40 wt%) were used to suppress cold flow of polyisobutylene (PIB)-based adhesives. Rheological measurements revealed the presence of the yield stress in the PIB-halloysite system which is indicative of the three-dimensional networ…
The technological potential of functionalized graphene has recently stimulated considerable interest in the study of the adsorption of metal atoms on graphene. However, a complete understanding of the optimal adsorption pattern of metal atoms on a graphene substrate has not been easy because of atomic relaxations at t…
Green synthesized metal NPs can potentially inhibit the proliferation of MCF-7 cells and trigger apoptosis through Bax/Bcl2 and caspase–cascade mediated mitochondrial dysfunction.
Abstract Thermal-insulation properties of textile materials play a significant role in material engineering of protective clothing. Thermal-insulation properties are very important from the point of view of thermal comfort of the clothing user as well as the protective efficiency against low or high temperature. Therm…
