Ballistic thermoelectric properties (TPs) in boron nitride nanoribbons (BNNRs) are studied using the nonequilibrium Green's function atomistic simulation of electron and phonon transport. A comparative analysis for TPs between BNNRs and graphene nanoribbons (GNRs) is made. Results show that the TPs of BNNRs are better…
Platinum/nickel bimetallic nanoparticles supported on multi-walled carbon nanotubes (xPtNi/CNTs) were synthesised. The fabrication process includes the chemical modification on the graphene surface of CNTs by acid treatment and the subsequent deposition of Pt or PtNi bimetallic nanoparticles with different composition…
In this study, we report the anti-proliferative effect and molecular mechanism of Chrysanthemum indicum (C. indicum) on A549 human alveolar basal epithelial cells. We also analyzed the changes in C. indicum component profiles due to modifications of predrying process, flower size, and extraction method. Among the vari…
Natural rubber, as well as natural reinforced rubber, with different carbon nanotubes concentrations, 10 and 20 mm, thick, have been structurally, chemically, and thermally investigated. Scanning electron microscopy techniques, as well as X-ray energy dispersive analysis, Raman, and thermal conductivity analysis, were…
We discuss the difficulties in discovering the Kondo effect in the resistivity of graphene. Similarly to the Kondo effect, electron-electron interaction effects and weak localization appear as logarithmic corrections to the resistance. In order to disentangle these contributions, a refined analysis of the magnetocondu…
Recent work has shown the effectiveness of structure-prediction methods in solving difficult molecular-replacement problems. The Rosetta protein structure modeling suite can aid in the solution of difficult molecular-replacement problems using templates from 15 to 25% sequence identity; Rosetta refinement guided by no…
A series of A3-type star poly(methylmethacrylate)/clay nanocomposites is prepared by in situ atom transfer radical polymerization (ATRP) initiated from organomodified montmorillonite containing quaternary trifunctional ATRP initiator. The first order kinetic plot shows a linear behavior, indicating the controlled char…
We reported that bulk superconductivity in Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ can be induced by annealing in Se and S vapor. The well-annealed samples show a large critical current density, emph{J}$_c$ $\sim$ 2 - 4 $\times$ 10$^5$ A/cm$^2$. Combined with our previous reports about O$_2$ and Te annealing effects, we proved t…
We report the use of the spray pyrolysis method to design self‐assembled isotropic ternary architectures made up of reduced graphene oxide (GO), functionalized multiwalled carbon nanotubes, and nickel oxide nanoparticles for cost‐effective high‐performance supercapacitor devices. Electrodes fabricated from this novel…
Cobalt (Co) addition and thermal annealing induced structural and vibrational properties of ZnO nanostructures were analysed. X‐ray diffraction pattern reveals that the nanostructures are in hexagonal wurtzite type and the formation of Co 3 O 4 . The Co ion induced morphology changes have been studied by high‐resoluti…
TiO 2 nanoparticles with an average diameter of less than 10 nm were prepared via a non‐hydrolytic sol–gel route in a TiCl 4 –diisopropyl ether–CH 2 Cl 2 system. After modification with n ‐octylphosphonic acid (OPA) to increase their organophilic character, the TiO 2 nanoparticles were used for preparation of TiO 2 /e…
Controlling the environmental degradation of polyhydroxybutyrate (PHB) and polyhydroxyvalerate (P(HB-co-HV)) bioplastics would expand the range of their potential applications. Combining PHB and P(HB-co-HV) films with the anti-fouling agent 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOI, <10% w/w) restricted microb…
We formulate a microscopic theory for the polymer transverse confinement length and associated dynamic potential for a mixture of infinitely thin rods and hard spheres based solely on topological entanglements and excluded volume constraints. For fixed spheres, the needle effective tube diameter decreases with particl…
Nanoparticles (NPs) could reach the food chain from diverse wastes containing these potentially toxic substances. We studied the mycoextraction of alumina (Al 2 O 3 ) NPs by mycelia of edible fungi: Pleurotus eryngii and Trametes versicolor . Mycelia were cultivated in liquid medium supplemented with alumina nanoparti…
Surface roughness of acrylonitrile–butadiene–styrene (ABS) resin prior to metallization is treated generally with sulphuric/chromic acid system. However, the presence of chrominum (VI) ion imposes serious environmental problems. In this work, TiO2 photocatalytic treatment was used to enhance the adhesion strength betw…
Three novel Pb oxyhalides, Pb3[O10Pb20](GeO4)4Cl10 (1), [O16Pb22][OPb](OH)I10(I,Br)(H2O) (2), and Pb5.5Si0.5O6Cl (3), have been prepared by high-temperature solid-state reactions (1 and 3) and hydrothermal method (2). The structure of 1 is based upon novel [O10Pb20](20+) layers of edge- and corner-sharing oxocentered…
Two fluorescent molecular receptor based conjugated polymers were used in the detection of a nitroaliphatic liquid explosive (nitromethane) and an explosive taggant (2,3-dimethyl-2,3-dinitrobutane) in the vapor phase. Results have shown that thin films of both polymers display remarkably high sensitivity and selectivi…
In this work, we introduce a simple approach to fabricate orthorhombic MoO3 (α-MoO3) nanobelts using sodium molybdate and dodecylbenzenesulfonic acid (DBSA). Importantly, DBSA not only acts as a reagent to provide H+, but also serves as a surfactant to stabilize and manipulate the morphology of the as-obtained product…
Multivalent cation rechargeable batteries are expected to perform well as high-capacity storage devices. Rechargeable magnesium batteries have an advantage in terms of resource utilization and safety. Here, we report on sulfur-doped vanadium pentoxide (S-V2O5) as a potential material for the cathodes of such a battery…
We investigated a series of nanocomposites, built of the hydrogen-bonded liquid crystal (LC) p-n-heptyloxybenzoic acid (7OBA) and single-walled carbon nanotubes (SWCNTs) by optical microtexture analysis and other complementary methods. The surface orientation strength of the LC cell and the bulk interaction of the dim…
