The interpretation of Raman spectra of soft modes in ferroelectric crystals is not easy because of its over-damped line shape and the complicated temperature dependence near the transition temperature. There exist not a few cases which are difficult to determine the transition type is either order-disorder or displaci…
= 10 mm above the burner exit. The fabrication of carbon nano-onions (CNOs) and carbon nanotubes (CNTs) was significantly enhanced by acoustic excitation at frequencies near the natural flickering frequency (ƒ = 20 Hz) and near the acoustically resonant frequency (ƒ = 90 Hz), respectively. At these characteristic freq…
Good stoichiometry of cadmium sulfide (CdS) film facilitates its application in photovoltaic devices; however, traditional thermal evaporation usually results in a Cd-deficient CdS film at a low-substrate temperature. In this study, Cd-rich CdS quantum dots (QDs) were synthesized by a facile co-precipitation method an…
This work investigates the phonon properties such as phonon dispersion relation, average group velocity, and phonon density of state (DOS) theoretically in GaN nanofilm under various surface stress fields. By taking into account of the surface energy effects, the elasticity theory is presented to describe the confined…
ABSTRACT Thermal processing of two potato protein isolates (PPIs) with glycerol as a plasticizer was explored in this study. The PPIs were pretreated by alkali or alkali under reducing conditions. The PPIs before and after pretreatment were analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis, differe…
Cell migration and invasion are integral to lung cancer metastasis. In this study, we investigated the combination of traditional chemotherapy and a layered double hydroxide (LDH) carrier as a new strategy for the inhibition of migration and invasion. To investigate the characteristics and possible mechanisms of VP16-…
Investigation of the crystal structure, microstructure, local ferroelectric, and magnetic properties of the Bi 0.9 La 0.1 Fe 1− y Ti y O 3 (0 ⩽ y ⩽ 0.1) perovskites has been carried out at room temperature to shed light on the conditions that favor the appearance of spontaneous magnetization in the polar phase of BiFe…
[NMe4 ]2 [TCNE]2 (TCNE=tetracyanoethenide) formed from the reaction of TCNE and (NMe4 )CN in MeCN has νCN IR absorptions at 2195, 2191, 2172, and 2156 cm(-1) and a νCC absorption at 1383 cm(-1) that are characteristic of reduced TCNE. The TCNEs have an average central CC distance of 1.423 Å that is also characteristi…
Cotton knitted fabrics were manufactured with different yarn types (conventional ring spun yarn and torque-free ring spun yarn) with different fibre types (combed cotton and combed Supima cotton) and yarn fineness (Ne30 and Ne40). These fabrics were then dyed with three types of dye (reactive, direct and sulphur dye)…
Modulation of living cell surfaces by chemical and biological engineering and the control of cellular functions has enormous potential for immunotherapy, transplantation, and drug delivery. However, traditional detection techniques have limitations in the identification of physical properties of viscoelastic films and…
Using density functional theory calculations with van der Waals corrections, we have investigated the stability and electronic properties of monolayer hexagonal boron nitride (hBN) on the Ni (111) surface. We have found that hBN can bind either strongly (chemisorption) or weakly to the substrate with metallic or insul…
The prime objective of this study was to fabricate epoxy polymer composite modified with graphene nanoplatelets (GP) and montmorillonite nanoclay (MMT) binary filler materials. Different loading percentages of individual and binary nanofillers were incorporated into an epoxy matrix system to investigate the synergisti…
Compatibilized and uncompatibilized composites containing various loadings of recycled polypropylene (RPP) and peanut shell powder (PSP) were prepared. An amount of 3 parts by weight per hundred parts of resin of poly(ethylene‐ co ‐acrylic acid) (PEAA) was used as a compatibilizer in the RPP/PSP composites. The effect…
High-resolution solid-state <sup>195</sup> Pt MAS NMR spectroscopy is a powerful technique for the characterization of Pt <sup>IV</sup> -containing polyoxometalates, as is demonstrated for several examples.
Expansion due to compression (EDC) test has been applied to evaluate the performance of nuclear fuel claddings where pellet-cladding mechanical interaction (PCMI) is introduced by swelling of fuel pellets and is triggered by the larger hoop deformation of the pellets, especially during accidental transients. The purpo…
Hybrid coatings consisting of a heat resistant Y2O3-Al2O3-SiO2 (YAS) glass containing 2.3 wt % of graphene nanoplatelets (GNPs) were developed by flame spraying homogeneous ceramic powders-GNP granules. Around 40% of the GNPs survived the high spraying temperatures and were distributed along the splat-interfaces, form…
ABSTRACT A facial and cost‐effective synthesis method of converting the leather protein solid wastes into a value‐added collagen matrix oil sorbent is successfully established for the first time. Hide powder fiber (HPF) was firstly prepared by using the pre‐tanned fleshing wastes from the leather industry, and then cr…
Effect of comprehensive alloying system (W, Ta, Nb, Mo, V, Hf, Ti, Zr, Ni) and impurity N on cohesive properties of the bulk and the special high-angle grain boundary (GB) Σ5 (210)[100] in Cr-base alloys, as well as segregation behavior of impurities at the GB and the (210) free surface are studied by first principles…
CaCO 3 polymorphs are intensively studied due to their importance in the nature and the widespread use in the industry as well. This work is dealing with the crystallization of aragonite from vaterite dispersion during the refluxation at 100°C. The characterization of CaCO 3 polymorphs during vaterite transformation w…
Abstract Multi‐compartmental non‐spherical hydrogel microparticles were fabricated by combining electrospinning and photopatterning. Sequential electrospinning produced multi‐layered fiber matrices with different composition in which each layer became a compartment of the particle. Photopatterning of the hydrogel in t…
