A simple process for preparing mesoporous transition metal nitrides by the ammonolysis of bulk ternary oxides that contain cadmium is reported. Mesoporous NbN, VN, Ta 3 N 5, and TiN have been obtained. The products were characterized by Rietveld refinement of powder X-ray diffraction patterns, scanning electron micros…
Well-crystalline Cd-doped ZnO multipods were synthesized by simple and facile hydrothermal process by using zinc chloride, cadmium chloride, hexamethylenetetramine and ammonium hydroxide at low-temperature. The synthesized materials were characterized in terms of their morphological, structural, compositional and opti…

Rice husk powder (RHP) is an agricultural by-product, and this research is carried out to incorporate RHP with natural rubber latex (NRL) compound and is foamed to make natural rubber latex foam (NRLF) using the Dunlop method. The tensile properties of modified NRLF is studied and compared with the controlled NRLF (ze…
Nanostructuring techniques have steered the performance of many thermoelectric (TE) compounds towards significant improvement in performance in the last two decades. In this paper, we present a comprehensive study on the effect of bulk nanostructuring in magnesium silicide (Mg2Si) through simulation of thermoelectric…
A new species of raphid pennate diatom producing a blue pigment, Haslea karadagensis Davidovich, Gastineau & Mouget, sp. nov., was recently isolated from the Crimean coast of the Black Sea (Ukraine). This organism is very similar to the well-known Haslea ostrearia, the first described ‘blue’ diatom, which produces mar…
Bi(2+)-doped BaSO(4) phosphor was synthesized in air via solid state reaction method. Three excitation bands and one emission band were observed at 260 nm ((2)P(1/2) → (2)S(1/2)), 452 nm ((2)P(1/2) → (2)P(3/2)(2)), 592 nm ((2)P(1/2) → (2)P(3/2)(1)), and 627 nm ((2)P(3/2)(1) → (2)P(1/2)), respectively. W-LEDs were demo…
Particulate polymer composites of isophthalic resin (ISO) filled with three lead oxides (PbO, PbO 2 and Pb 3O 4) were prepared with different filler concentrations and investigated for radiation shielding properties of gamma rays from Ba-133, Cs-137 and Co-60 point sources. Among the three composite combinations, ISO+…
We report a theoretical study on molecular structure, vibrational spectra, nonlinear optical (NLO), and natural bond orbital (NBO) analysis of sarcosine‐maleic acid (C 7 H 11 NO 6 ) in the ground state calculated by using the Hartree‐Fock (HF) and density functional method (DFT/B3LYP) with 6–31++G(d,p) basis set. We r…
Bentonite particles are widely used for different applications such as drilling fluid, bleaching earth, catalyst, nanoclays, etc. Bentonite is rich in Montmorillonite, which is a nanostructured and nanoporous clay mineral. To characterize bentonite it is important to distinguish different components of clay mineral ad…
Nanoparticle encapsulation has been used as a means to manipulate the pharmacokinetic (PK) and safety profile of drugs in oncology. Using pegylated liposomal doxorubicin (PLD) vs. conventional doxorubicin as a model system, we developed and experimentally validated a multiscale computational model of liposomal drug de…
P-type nanostructured bulk Si0.8Ge0.2 and Si0.8Ge0.2 composites with CrSi2 nano-crystallite inclusions were synthesized via sintering approach. The composite structure showed power factor enhancement compared with nanostructured Si0.8Ge0.2 alloy. The experimental data for both structures were modeled with solving the…
In order to improve the biodegradation properties of the magnesium alloy, a bioactive hydroxyapatite (HA) coating was deposited on AZ60 magnesium alloy by a two-step chemical method, i.e., dicalcium phosphate dihydrate (DCPD) coating was formed through a phosphating process, and then transformed to hydroxyapatite coat…
The objective of this paper is to discuss the results of the ballistic testing of spark plasma sintered TiB2-Ti based functionally graded materials (FGMs) with an aim to assess their performance in defeating small-calibre armor piercing projectiles. We studied the efficacy of FGM design and compared its ballistic prop…
Abstract The exoskeleton of crustaceans is formed by the cuticle, a chitin-protein-based nano-composite with hierarchical organization over at least eight levels. On the molecular level, it consists of chitin associated with proteins forming fibres, which are organized in the form of twisted plywood. On the higher lev…
Friction reduction in microchannel flows can help alleviate the inherently taxing pumping power requirements associated with the dimensions involved. One possible way of achieving friction reduction is through the introduction of surface microtexturing that can lead to a superhydrophobic Cassie-Baxter state. The Cassi…
Molecular dynamics (MD) simulations have been conducted using an assembly consisting of 105 indomethacin (IMC) molecules and 12 water molecules to investigate the underlying dynamic (e.g., rotational and translational diffusivities and conformation relaxation rates) and structural properties (e.g., conformation, hydro…
Molecular-dynamics simulations based on many-body interatomic potentials are conducted to investigate the clusters of discrete breathers in graphene under in-plane homogeneous strain. It is found that the discrete breather clusters can easily be excited when the gap in the phonon density of states is introduced by the…
Prior studies have demonstrated that superhydrophobicity of submerged surfaces is influenced by hydrostatic pressure and other environmental effects. Sustainability of a superhydrophobic surface could be characterized by both how long it maintains the trapped air in its surface pores, so-called “longevity,” and the pr…
A series of ordered mesoporous/microporous carbon materials with controllable micropore size was prepared from chlorination of ordered mesoporous titanium carbide/carbon composites obtained by an evaporation induced self-assembly approach. The proportion of micropores can be tuned easily by changing the Ti content in…
