Despite the long-lasting interest in the synthesis control of nanoparticles (NPs) in both fundamental and applied nanosciences, the driving mechanisms responsible for their size and shape selectivity in an environment (solution) are not completely understood, and a clear assessment of the respective roles of equilibri…
The influence of carbon and copper on the original structure of cast Fe-Cr-Cu-C alloys, as well on the formation of the secondary structure and tribological characteristics of cast alloys under dry and boundary friction conditions has been shown.
We theoretically predict the rate of transcription (TX) in DNA brushes by introducing the concept of TX dipoles that takes into account the unidirectional motion of enzymes (RNAP) along DNA during transcription as correlated pairs of sources and sinks in the relevant diffusion equation. Our theory predicts that the TX…
Ba0.8Sr0.2Ce0.8−x−yZryInxY0.2O3−δ (x = 0.05, 0.1 y = 0, 0.1) proton-conducting oxides are prepared using a solid state reaction process. The effect of indium contents on the microstructures, chemical stability, electrical conductivity, and sintering ability of these Ba0.8Sr0.2Ce0.6Zr0.2InxY0.2−xO3−δ oxides were system…
Differential pulse voltammetric studies on DPE-I and DPE-II indicating selective response to Fe 3+ , supported by DFT studies using Gaussian software.
Cu2S is known to be a promising solar absorber material due to its suitable band gap and the abundance of its constituent elements. Cu2S is known to have complex phase structures depending on the concentration of Cu vacancies. Its instability of phases is due to favorable formation of Cu vacancies and the mobility of…
The microstructure, hydrophobicity and chemical composition of butterfly wing surfaces were investigated by a scanning electron microscope (SEM), a video-based contact angle meter, and a Fourier transform infrared spectrometer (FT-IR). Using CaCO3 particle as simulated pollutant, the self-cleaning performance of the w…
Hybrid spin-transition nanoparticles (HSTNs) have been prepared by the formation of octahedral Fe( ii ) complexes at the surface of silica nanoparticles.
A nanocarrier with a diameter less than 30 nm was prepared here by using host–guest chemistry. A defined number of functionalized guests was incorporated in the nanocarrier, which was a nice tumor imaging probe without showing the ABC phenomenon.
The intergrain interface of unconventional superconductors suppresses the order parameter and, thus, serves as a bottleneck for the supercurrent. Such a characteristic of the grain interface is a major limiting factor for the lossless-current-carrying capacity of superconducting transmission lines on the one hand, but…
Exact analytical solutions of nonlinear equations describing directional solidification of binary melts with a mushy layer are constructed. The primary interdendritic spacing in a mushy layer is analytically found on the basis of the selection theory of stable dendritic growth.
Dibenzothienyl Schiff bases, DBT-NN and DBT-NP, were derived from condensation of 4-formyldibenzothiophene with N,N-dimethylethylenediamine and 2-(diphenylphosphino)ethylamine, respectively. A photochemical reaction of [Fe(CO)5] with DBT-NN produced diiron complexes, [Fe2(μ-DBT-NN)(CO)6] (1) and [{Fe(μ-BPT-NN-κ(3)S,C,…
We are reporting a new diagnostic test system for evaluating nanomaterial toxicity on halophile green microalgae Dunaliella salina based on colorimetric measurements enabling us to estimate cell death and growth-rate inhibition in microalgae suspension for serial dilutions of several toxicants. The principle of the me…
The influence of NH4Cl on hydrothermal formation of CaSO4·0.5H2O whiskers from CaSO4·2H2O precursor at 135°C was investigated in this paper. Compared with the blank experiment, the presence of 3 × 10−2 mol·L−1 NH4Cl led to the increase of the lengths of the whiskers from 50 to 160 μm to 150 to 300 μm and the decrease…
Thermal evaporation was developed to fabricate Ga doped CdS core–Sb doped ZnTe shell p–n nano-heterojunctions, which exhibit obvious sensitivity to 638 nm illumination, with a responsivity and a detectivity of 1.55 × 10 3 A W −1 and 8.7 × 10 13 cm Hz 1/2 W −1 , respectively.
The rheological behavior of composites made with low-density polyamide 11 (PA11) and high yield pulp fibre (HYP) is evaluated. The rheological properties of high-yield, pulp-reinforced bio- based Nylon 11 HYP/PA11 composite were investigated using a capillary rheometer. The rheological tests were realized in function…
Cd x :CuInS 2 quaternary QDs were obtained in a one-pot reaction; these quaternary QDs exhibited enhanced photovoltaic performance compared to pristine CuInS 2 ternary QDs.
(Ti,Cr)C was synthesized and consolidated in situ by spark plasma sintering (SPS) of two TiC/Cr3C2 powder mixtures of distinctly different particle sizes. SPS of both mixtures successfully produced single-phase (Ti,Cr)C in two minutes at 1800°C. It was found that the nano-scale mixture consists of fine and uniformly d…
Condensation of rhodaminehydrazone with naphthalene-1-carboxaldehyde generates a colourless probe, RDHDNAP that can selectively detect Hg 2+ through generation of a pink color along with significant fluorescence enhancement.
This study investigates the wear and friction characteristics of surface–modified aluminium alloys of JIS AC4CH–T6 and A6061–T651. The aluminium alloys were individually treated with five surface modifications, including anodising, anodising/MoS2, electroless Ni, electorless PTFE and DLC. Dry wear tests of thrust–wash…
