Copper oxide (CuO) is a p-type semiconductor having a band gap energy of 1.5 eV, which is close to the ideal energy gap of 1.4 eV required for solar cells to allow good solar spectral absorption. The inherent electrical characteristics of CuO nanoparticles make them attractive candidates for improving the performance…
It is difficult to determine dopamine (DA) and 5-hydroxytryptamine (5-HT) accurately because of the interference of ascorbic acid (AA) in vitro, which has a high concentration and can be oxidized at a potential close to DA and 5-HT at a conventional electrode, combined with the overlapping voltammetric signal of DA and…
Poor or inefficient lubrication often gives rise to high friction and wear losses in machine components, which adversely affect their performance, efficiency, and durability. Many approaches are being explored to enhance the antifriction and antiwear properties of sliding machine components. In this study, the antifri…
Mesenchymal stem cells (MSCs) have been extensively explored in a variety of regenerative medicine applications. The relatively large size of MSCs expanded in tissue culture flasks leads to retention in the microcirculation of the lungs following intravenous delivery, reducing their capacity to reach target sites. We…
BACKGROUND: Macrophages may concentrate ultrasound contrast agents and exhibit selective adhesion to activated endothelium. The present study investigates in mice the potential of perfluorohexane (PFH) loaded macrophages to act as ultrasound contrast agent with high reflectivity and specifically targeted at (atheroscl…
Abstract The existence of a zone containing a low concentration of Y2BaCuO5 (Y-211) phase particles in the vicinity of the seed in single grain, bulk Y?Ba?Cu?O (YBCO) superconductors fabricated by the top seeded melt growth (TSMG) technique has been reported, suggesting the presence of low intrinsic magnetic flux pinn…
The approach of this work was to study the capability of graphene-based materials in the field of biological sample preparation. A polypyrrole/graphene composite was synthesized and characterized. The potential of the nanocomposite was investigated as a sorbent in dispersive solid-phase extraction followed by high-per…
Effects of nano-clay on weight loss of wood-plastic composites (WPC) by five fungi were studied. Nanoclay particles of 20 to 50 nm size were applied at 2, 4, and 6% WPC of 0,90 g/cm3 density. The white-rot fungi Physisporinus vitreus, Pleurotus ostreatus and Trametes versicolor as well as the brown-rot species Antrodi…
The magnetic response of the Fe@Sn 12 cluster is investigated by magnetic beam deflection experiments. In contrast to Mn@Sn 12, the molecular beam of this cluster is deflected almost exclusively toward increasing field, also at low temperatures, supposable due to Jahn–Teller induced distortions of the tin cage. The ma…
Abstract In this paper, we propose a new approach for the preparation of sodium‐ and carbonate‐substituted apatite by a wet precipitation method in aqueous media at 23 °C. The main difference between this method and conventional techniques is that poorly crystalline calcium phosphates are obtained and then heated to f…
Abstract Three metal complexes based on the flexible bis(benzimidazole) derivatives, namely [Co2(L1)4(pydc)2]·2H2O (1), {[Cu(L1)(pydc)]·0.75H2O}n (2), and [Co2(L2)2(pydc)2]·8H2O (3), [L1 = 1,2‐bis(5,6‐dimethylbenzimidazol‐1‐ylmethyl)benzene, H2pydc = 2,6‐pyridinedicarboxylic acid, L2 = 1,4‐bis(5‐methylbenzimidazol‐1‐y…
A highly efficient catalytic system composed of a bifunctional polyacrylonitrile fiber (PANF-PA[BnBr]) and a metal chloride was employed to produce 5-hydroxymethylfurfural (HMF) from sucrose in mixed-aqueous systems. The promoter of PANF-PA[BnBr] incorporates protonic acid groups that promote the hydrolysis of the gly…
As a promising material for photoelectrical application, MoS2 has attracted extensive attention on its facile synthesis and unique properties. Herein, we explored a novel strategy of laser ablation to synthesize MoS2 fullerene-like nanoparticles (FL-NPs) with stable photoresponse under high temperature. Specifically,…
A set of diverse monomers were synthesized using combinatorial chemistry and tested using our unique high-throughput screening platform. The versatility of our platform is exemplified by possible applications in reducing biological fouling on ship hulls, filtration membranes, and surgical instruments, to name a few. T…
Enzyme encapsulation is a simple, gentle, and general method for immobilizing enzyme, but it often suffers from one or more problems regarding enzyme loading efficiency, enzyme leakage, mechanical stability, and recyclability. Here we report a novel, simple, and efficient method for enzyme encapsulation to overcome th…
ABSTRACT Electrospun nanofiber matrices have attracted a great deal of attention as matrices for skin repair and regeneration. The current manuscript reports the fabrication and characterization of a bioactive polycaprolactone (PCL) fiber matrix for its ability to deliver multiple factors. Bioactive PCL matrices were…
The morphology and microstructure of crystalline drug/polymer solid dispersions could influence their physical stability and dissolution performance. In this study, the drug crystallization mechanism within PEG, PPG, and poloxamer matrix was investigated, and the resultant microstructure of various solid dispersions o…
This study probes the nature of noncovalent interactions, such as cation-π, metal ion-lone pair (M-LP), hydrogen bonding (HB), charge-assisted hydrogen bonding (CAHB), and π-π interactions, using energy decomposition schemes-density functional theory (DFT)-symmetry-adapted perturbation theory and reduced variational s…
The interaction of proteins with endotoxins has divergent effects on lipopolysaccharide (LPS)-induced responses, which serve as a basis for many clinical and therapeutic applications. It is, therefore, important to understand these interactions from both theoretical and practical points of view. This paper advances th…
We employed the complete active space self-consistent field (CASSCF) and its multistate second-order perturbation (MS-CASPT2) methods to explore the photochemical mechanism of 2-hydroxyazobenzene, the molecular scaffold of Sudan I and Orange II dyes. It was found that the excited-state intramolecular proton transfer (…
