Zwitterionic molecules are known to resist nonspecific protein adsorption and have been proposed as an alternative to the widely used polyethylene glycol. Recently, zwitterionic-like nanoparticles were created from the coimmobilization of positive and negative ligands, resulting in surfaces that also prevent protein c…
Oxygen stoichiometry in (U,Pu)O2-x nuclear fuels, while of prime interest, is still difficult to be determined at the micrometric scale. It has been recently evidenced that Raman microscopy is a promising tool to characterize (U,Pu)O2-x samples at a microscopic scale by probing the oxygen sublattice. Its use for deter…
We propose a scheme for sensing of an oscillating field in systems with large inhomogeneous broadening and driving field variation by applying sequences of phased, adiabatic, chirped pulses. These act as a double filter for dynamical decoupling, where the adiabatic changes of the mixing angle during the pulses rectify…
This article proposes a novel approach in order to understand the different kinds of core loss of the trapezoidal flux waveform. The proposed approach is based on the theory of magnetism and assessed with the experimental results to show that the total loss is composed of two terms: the effective triangular loss durin…
Abstract Molecular bond dissociation and formation reactions induced by localized surface plasmons of metal nanostructures are promising reactions in terms of the effective utilization of sunlight. The plasmon has a potential not only to enhance photochemical reactions but also to enable efficient novel reaction pathw…
The influence of the degree of homogeneity of the SiO2 sol on the duration of the induction period and the quality of fire-resistant coatings on textile materials was studied. The prospects of using IR spectroscopy as an express method for studying the phase composition of a gel coating, the degree of completion of th…
With continuing progress in the chemical synthesis of colloidal semiconductor nanocrystals (NC), one property that remains elusive to the rational design is the ensemble photoluminescence (PL) line width. Given the growing demand for NC-based light-emitting materials, substantial research effort has been dedicated to…
Effect of content of synthetic aluminosilicates in medium-density polyethylene on the fire hazard characteristics and mechanical properties of compositions is investigated. It has been shown that during decomposition of the filler with the release of water, its effectiveness depends not only on the endothermic effect…
Abstract A dramatic change in the magnetic behaviour, which solely depends on the parity of the organic linker molecules, has been found in a family of layered CoII hydroxides covalently functionalized with dicarboxylic molecules. These layered hybrid materials have been synthesized at room temperature using a one‐pot…
Whether in turbine components or exhaust gas heat exchangers, vacuum-brazed nickel-based joints are subjected to varying cyclical loads during their applications, often in corrosive environments. The microstructure of the brazed seam, which is determined by the alloy composition and the brazing process parameters, is…
Abstract Herein, we report a novel approach that involves Pickering stabilization of micometer-sized liquid crystal (LC) droplets with biocompatible soft materials such as a whey protein microgel (WPM) to facilitate the analysis of analyte-induced configurational transition of the LC droplets. The WPM particles were a…
High Resolution Image Download MS PowerPoint Slide We investigate the chemo-photothermal effects of gold nanorods (GNRs) coated using mesoporous silica (mSiO 2 ) loading doxorubicin (DOX). When the mesoporous silica layer is embedded by doxorubicin drugs, a significant change in absorption spectra enables to quantify…
Recent advances in high-throughput computational workflows are expanding the realm of materials for a range of applications. Here, we report the experimental evaluation of two such predicted candidate ferroelectric perovskite oxides: BiAlO 3 and BiInO 3 . Attempts were made to synthesize polar BiAlO 3 and BiInO 3 usin…
In recent years, the molecular self-assembly approach has witnessed a sudden surge in coassembly strategy to achieve extensive control over accessing diverse nanostructures and functions. To this direction, peptide-peptide coassembly has been explored to some extent in the literature, but protein-peptide coassembly is…
The structural and electromagnetic shielding properties of NBR rubber filled with magnetite (Fe3O4) were studied. Rubber composite materials with ore magnetite and synthetic magnetite have been produced separately in order to observe its differences. Samples have been fabricated using a rubber mill and different magne…
Abstract What happens when the extremely adhesive and versatile chemistry of polydopamine (PDA) is in contact with the extremely slippery surfaces known as slippery liquid‐infused porous substrates (SLIPS)? Inspired by the pitcher plant, SLIPS possess excellent repellence against a variety of complex liquids and have…
Plasmon-induced hot carriers can be used to control both the growth and the etching behavior of gold nanoparticles (Au NPs) with laser irradiation. Here, the Au NPs placed on Si substrate are irradiated with a continuous wave laser (641 nm) in the presence of HAuCl 4 solution. Irradiation results in growth/etching of…
Two different silane treatment methods were used to improve the reinforcing activity of carbon nanofibers (CNF) in acrylonitrile-butadiene rubber (NBR) composites. The first method was chemical silanization with [3-(2-aminoethylamino)propyl]trimethoxysilane (APTS) in ethanol solution, preceded by oxidation of the CNF…
Recently, carbon fiber reinforced thermoplastics (CFRTP) have been widely used for various applications instead of carbon fiber reinforced thermosetting plastics (CFRP). Some matrix resins of CFRTP are crystalline polymers such as polyamide (PA), polyetheretherketone (PEEK), and polyimide. In this study, carbon fiber…
Abstract Low-cost, scalable, and abundant biomass-derived carbon materials have attracted considerable attention. Herein, we report on novel self-doped (nitrogen) porous carbon nanosheets by carbonization/activation of acorn shells as a biomass precursor for use in high-performance supercapacitors (SCs), which contain…
