Mechanically resilient mats consisting of overlaid electrospun nanofibers with self-generated TiC crystallites embedded in a carbon matrix are surface-decorated with Pt nanoparticles as a novel electrocatalytic system for oxygen reduction reaction. Electrocatalytic activities (e.g., on-set potential and current densit…
The principles of the holographic lithography technique are reviewed, and the ability in the formation of structures with different periods by the holographic lithography technique in SZ2080 is demonstrated. The influence of laser exposure, phase shift between interfering laser beams, and the used laser wavelength on…
Pervaporation in recent years has received strong attention from industry as a novel, energy-efficient and environmental- friendly separation technology.Pervaporation reactor is a new technology to enhance conversion in reversible esterification reactions. In present work, polyvinyl alcohol-polyether sulfone (PVA-PES)…
A novel strategy for the preparation of nitrogen-doped carbon is presented that is based on the use of azole-functionalized diacetylenic precursors (imidazole and benzimidazole). As demonstrated by thermal analyses (TGA, DSC) and spectroscopic measurements (IR, 13C solid-state NMR), these diacetylenic molecules underg…
Wire and cable fire has become the major cause of fire disaster in China. Effective evaluation and analysis of the flammability of cables are critical for developing new flame retardant cable materials by the industry and testing cables which have already been used in the market. Due to the complex internal structure…
The electrochemical impedance spectroscopy was applied in order to characterize and compare the dependence of differential capacitance on temperature at the Cd(0001) | 1-ethyl-3-methylimidazolium tetrafluoroborate and Cd(0001) | 0.1 x M KI + 0.033(1− x ) M K 2 SO 4 interfaces. For both systems, the impedance spectra w…
New framework solids consisting of coordination polymers [Ce(L)(DMA)(H2O)]n (1), [Nd(L)(DMA)(H2O)]n (2), [Cu2(OH)(L)]n (3) and [Cd2(L)2(4,4′-bipyridyl)]n·(CH3NH2CH3+)2n (4) (H3L = 3,5-(4-carboxybenzyloxy) benzoic acid; DMA = dimethyl acetamide) have been synthesized under hydro(solvo)thermal conditions and characteriz…
BACKGROUND: Assessing protein modularity is important to understand protein evolution. Still the question of the existence of a sub-domain modular architecture remains. We propose a graph-theory approach with significance and power testing to identify modules in protein structures. In the first step, clusters are dete…
Boron-modified pyrrole-based anion receptors (catechol-boron and diphenylboron dipyrrolyldiketone derivatives) formed planar receptor-anion complexes, leading to charge-by-charge assemblies with planar cations, as in the corresponding difluoroboron derivative.
Novel nanostructures, e.g. core–shell or yolk–shell, sword–sheath, coaxial nanotubes, etc., are extensively explored for their potential application in modifying electrode durability in lithium-ion batteries (LIBs). Herein, hybrid nanostructures of monodisperse tin dioxide nanocrystals inclusion in highly ordered meso…
For the first time, the combination of the homoleptic erbium tris-guanidinate metalorganic complex ([Er(NMe2-Guan)3]) simply with water yielded high quality Er2O3 thin films on Si(100) substrates employing the atomic layer deposition (ALD) process. The process optimization to grow good quality Er2O3 layers was perform…
Cu-doped CdS thin films of variable doping levels have been deposited on indium tin oxide-coated glass substrate by simple and cost-effective ultrasonic spray pyrolysis. The influences of doping concentration and annealing treatment on the structure and photoelectrochemical properties of the films were investigated. T…
BACKGROUND: P-gp expression has been linked to the efflux of chemotherapeutic drugs in human cancers leading to multidrug resistance. Fluorescence techniques have been widely applied to measure the P-gp activity. In this paper, there is a comparison between the advantages of two fluorescence approaches of commonly ava…
A three-dimensional (3D) porous structure of [Cu3(μ3-OH)(μ2-O)(dmtrz)2(HCOO)(μ2-H2O)(H2O)3]·H2O (1) has been in situ solvothermally synthesized. In 1, the trinuclear triangular [Cu3(μ3-OH)(μ2-O)(dmtrz)2] cluster connects itself infinitely, resulting in the type-II channel structure, which is different from that of the…
In the conventional iron-making process, the oxygen potential in the hearth of the blast furnace is determined only by the temperature because of the carbon-saturated conditions. As a consequence, impurities such as phosphorus are reduced and dissolved in the iron because of the excessively low oxygen partial pressure…
Cold atmospheric pressure plasmas (CAPs) are being investigated for medical applications, and the first clinical studies are promising. However, interactions between plasmas and biological samples are only partly understood on a molecular level. In this study, bovine serum albumin (BSA), a standard model for plasma-me…
Hydration of various alkenes proceeded over a platinum-loaded titanium oxide photocatalyst. It is notable that, unlike conventional acid-catalysts, the photocatalyst preferentially promoted the hydration according to the anti-Markovnikov rule. The results of some reaction experiments and semiempirical molecular orbita…
The use of acoustic radiation force has been suggested for enhancing the delivery of therapeutic substances, whereas sonothrombolysis has been developed for years as treatment by itself, or in combination with thrombolytic agents or ultrasound contrast agents. We have examined the efficacy of using acoustic radiation…
In this study, solder ball incorporated polyvinylidenefluoride (PVDF) nanofiber was added into the ACF system to overcome short circuit issues of fine pitch flex‐on‐flex (FOF) assembly. Also, in order to improve the thermal mismatch of the flexible substrate which can lead to electrode misalignment during the bonding…
We have prepared single crystalline SnO2 and ZnO nanowires and polycrystalline TiO2 nanotubes (1D networks) as well as nanoparticle-based films (3D networks) from the same materials to be used as photoanodes for solid-state dye-sensitized solar cells. In general, superior photovoltaic performance can be achieved from…
