Abstract The thermoelectric properties of bismuth telluride (Bi 2 Te 3 ) nanoplate thin films were estimated using combined infrared spectroscopy and first-principles calculation, followed by comparing the estimated properties with those obtained using the standard electrical probing method. Hexagonal single-crystalli…
Since the first description of cellulose molecule in 1838 by the French chemist Anselme Payen, passing through the obtention of nanocellulose in 1977 [1], until the published researches up to 2017, too many advances and different approaches were given to this multifunctional polysaccharide from pulp and paper industry…
Cu-Schiff base complex which we previously synthesized (Kilinc et al., 2012) is supported on Al2O3. The prepared catalyst is characterized by using SEM, XRD, BET, and FT-IR methods. And Al2O3-supported complex is used as a catalyst in NaBH4 hydrolysis reaction for hydrogen generation. NaBH4 hydrolysis reactions are in…
The green synthesis of silver nanoparticles (AgNPs) is a good approach to avoiding the drawbacks associated with by-products formed in chemical synthesis. The present investigation was intended to synthesize AgNPs using gallnut extract as reducing agent and evaluate their potential biomedical applications. The ultravi…

The US is frontrunner regarding implementation of GHG related legislation with the introduction of GHG phase 1 and…
Three different mechanisms are identified to contribute to thermal resistances across a carbon nanotube–graphene junction: material mismatch, nonplanar junction, and defects. To isolate the contributions of each mechanism, we have designed five types of junctions and performed nonequilibrium molecular dynamics simulat…
<div class="section abstract"><div class="htmlview paragraph">Natural gas-powered engines are widely used due to their low fuel cost and in general their lower emissions than conventional diesel engines. In order to comply with emissions regulations, an aftertreatment system is utilized to treat exhaust fr…
The reaction between amethyrin and non-aqueous uranyl silylamide (UO2[N(SiMe3)2]2) under anaerobic conditions affords a bench-stable uranyl complex. UV–vis spectroscopy, cyclic voltammetry, as well as proton NMR spectroscopic analyses provide support for the conclusion that all six pyrrole subunits participate in coor…

Metal/semiconductor nanocomposite systems with the ability of controllable holographic storage are fascinating for advancing information technology. Ag/TiO2 nanocomposite films present multicolor photochromism, which plays a key role in high-density optical memory. However, the film undergoes a reversible photo-redox…

Both the peak temperature and the maximum temperature gradient of the DPF during active regeneration should be well cont…
Crack-free zirconia ceramics were consolidated via sintering by intense thermal radiation (SITR) approach at 1600–1700°C for 3–5 min. The resulted ceramic bulks can achieve a relative density up to 99.6% with a grain size of 300–1200 nm. Their bending strength, Vickers hardness and indentation toughness values are up…
Several populations of a new Craspedostauros species were observed on museum specimens of juvenile green turtle and Kemp’s ridleys collected from Long Island Beach, New York, USA. The new taxon, Craspedostauros alatus Majewska & Ashworth sp. nov., exhibits a distinctive set of morphological features typical of the gen…
Heteroepitaxial magnetoelectric (ME) composites are promising for the development of a new generation of multifunctional devices, such as sensors, tunable electronics, and energy harvesters. However, challenge remains in realizing practical epitaxial composite materials, mainly due to the interfacial lattice misfit st…
Methods used to compare the effectiveness of liming materials (e.g., relative neutralizing value, RNV; effective calcium carbonate equivalent, ECCE) were developed for ground limestone. This method is relatively untested on industrial byproducts that could be used when limestone is expensive or unavailable. The object…
Thin film energy storage technology has great potential in emerging applications. The concept of integrating a smart window and energy storage provides an ideally large area for a thin film battery and a structural power backup for an energy-efficient building. However, due to the limited number of candidate materials…
Ordered self-assembly of small organic molecules may induce novel properties in a supramolecular arrangement and can act as advance functional materials. This paper discusses the development of a new stimuli-responsive dipeptide hydrogelator containing l-phenylalanine and α-aminoisobutyric acid (Aib). The dipeptide Bo…
Abstract By means of metal organic deposition using trifluoroacetates (TFA-MOD), we replaced and localized two or more atoms in a single-crystalline structure having almost perfect orientation. Thus, we created a new functional structure, namely, clustered atom-replaced structure (CARS), having single-crystal-like met…
In this work, an attempt to correlate chemical, mineralogical, textural and physical properties of red clays of Morbi-Wankaner region, Gujarat (India) were made using various characterization techniques. General properties, such as specific gravity, slaking nature and grit content were noted. Bulk chemical composition…
