Ester-functionalized styrene-butadiene rubber (dibutyl itaconate-styrene-butadiene rubber) (D-ESBR) was synthesized by low-temperature emulsion polymerization using dibutyl itaconate (DBI) as a modified monomer containing ester groups. Nonpetroleum-based silica with hydroxy groups was used as a filler to enhance the D…
In this ab initio study, we investigate the initial stages of small polaron formation across four metal peroxides. By separating out electronic and lattice energy contributions to the formation of electron polarons, we find both large and small formation barriers directly correlated with an electronic relaxation delay…
Poor solubility and bioavailability of drugs are often affected by its microscopic structural properties. Nitrofurantoin (NF), a Biopharmaceutics Classification System class II item, has a low water solubility with low plasma concentrations. To improve its therapeutic efficacy, formulation strategy of solid dispersion…
Pyridoxine hydrochloride, commonly known as vitamin B 6 (VB 6 ), is considered to be one of the most essential vitamin enhancers. Understanding its crystal morphology is of paramount interest in the pharmaceutical industry. Herein, we systematically investigate the crystallization of VB 6 in the absence and presence o…
The acoustic emission (AE) method has been widely recognized for the detection of incipient insulation fault phenomenon (partial discharge, PD) in power transformers, nevertheless, the installation and placement of AE sensors should be taken into full consideration. In this manuscript, a three-dimensional multiphysics…
This study was carried out for biosynthesis of gold nanoparticles using Scytosiphon lomentaria (brown algae) and Spyridia filamentosa (red algae) and compared. Synthesized gold nanoparticles were characterized using the UV-Vis spectroscopy (UV-Vis), Fourier transform infrared (FTIR) and Master Sizer analysis. Antioxid…
The effect of grain size in the range 72 to 190 μm and carbon content in the range 0.105–0.073 wt.% on the intergranular corrosion of the austenitic stainless steel 301 has been investigated. Grain boundary chromium depletion has been studied directly using energy dispersive X-ray spectroscopy combined with scanning t…
Abstract Various combinations of zinc borate (ZB), alumina trihydrate (ATH) and magnesium hydroxide (MH) were used to retard the flammability of PVC composite. Flame retardancy of samples were investigated with limiting oxygen index (LOI) test. Further testing was achieved to expose the individual and synergistic effe…
In many application fields, such as medicine or sports, heating textiles use electrically conductive multifilaments. This multifilament can be developed from conductive polymer composites (CPC), which are blends of an insulating polymer filled with electrically conductive particles. However, this multifilament must ha…
Abstract Two highly sulfonated micro/mesoporous polymers, P(1,3‐DEB)‐SO3H and P(1,4‐DEB)‐SO3H, with permanent porosity, the specific surface area about 550 m2 ⋅ g−1 and the content of SO3H groups of 2.7 mmol ⋅ g−1 were prepared as new acid Porous Polymer Catalysts, PPCs. The PPCs were achieved by easy sulfonation of p…
Due to the toxicity and resistance of anticancer drugs, various methods have been investigated to improve their effects in cancer treatment. Since boron nitride nanotubes (BNNTs) are biocompatible and nontoxic, they can act as fine drug delivery vehicles of these anticancer drugs to deliver them directly to the target…
Abstract A surface digging effect of supported Ni NPs on an amorphous N‐doped carbon is described, during which the surface‐loaded Ni NPs would etch and sink into the underneath carbon support to prevent sintering. This process is driven by the strong coordination interaction between the surface Ni atoms and N‐rich de…
1,6-Hexylenediamine (HMDA) was chosen to replace part of ethylene glycol to develop a novel poly(ethylene terephthalate) structure with amide bonds. Four kinds of poly(ester amide)analogues (p-ETA) with different contents of amide bonds (1–4 mol %) were successfully synthesized via a new simple synthesis procedure. It…
Abstract Isolated or contiguous, the surface distributions of Pd atoms in the Pd−Au bimetallic nanoparticle (NP) catalysts often influence activity and selectivity towards specific reactions. In this study, we used a concomitant Pd hydride formation upon H2 exposure as a probe of presence of contiguous Pd regions in b…
High-efficient-adsorbents-layered double hydroxides (LDH) intercalated by carbonate ion and ethylenediaminetetraacetic acid (EDTA) ion were synthesized by the coprecipitation method for the removal of Ni 2+ in the aqueous solution. MgAl–EDTA–LDH had a better adsorption performance than MgAl–CO 3 –LDH due to the larger…
Bearing is the most important component for nearly all mechanical equipment. Nanostructured bainitic steel, which is a new bearing steel, not only possesses necessary hardness and higher toughness, but exhibits excellent wear resistance and rolling contact fatigue performance, making it suitable for bearing applicatio…
The adhesion feature of graphene on metal substrates is important in graphene synthesis, transfer and applications, as well as for graphene-reinforced metal matrix composites. We investigate the adhesion energy of graphene nanosheets (GNs) on iron substrate using molecular dynamic (MD) simulations. Two Fe–C potentials…
: Reports about the influence of cerium-oxide nanoparticles (nCeO2) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO2 with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, an…
Because of the insulation issue in the high‐voltage system of spacecrafts, the dielectric and space charge characteristics of polyether‐ether‐ketone (PEEK) insulating material are studied in this paper. The electric conduction, trap parameters and space charge characteristic of PEEK, especially the space charge distri…
Abstract In this work, we have studied the influence of different anionic species, including typical Hofmeister ions (citrate3– and SCN–), hydrophobic ions (tetraphenyl borate, Ph4B–), and polyoxometallic clusters (Keggin-type POM, PW3–), on the electrophoretic mobility of colloidal particles of a different nature, ch…
