The phase change temperature and enthalpy change as a function of polystyrene (PS) concentration in dimethylformamide through a dynamic heating and quenching process were investigated. Cold crystallization, freezing and melting phenomena in a 10 wt% PS solution were all observed. Cold crystallization and melting pheno…
In this study, TiB2/7075 aluminum matrix composites were prepared via in situ synthesis. It was found that TiB2 particles are mainly quadrate. Large TiB2 particles (1–2 μm) agglomerate at grain boundaries, but most of the particles are on the submicron scale. Adding 4.5 wt.% TiB2 particles effectively optimizes α-Al g…
The application of nanotechnology with the new electronic materials led to the development of nanorobots.Nanorobots, in the nano scale region are capable of entering the cell for diagnosis, treatment and surgery.Due to its wide range of applications, nanorobots are designed with specific materials and design technolog…
Aggregation and aggregates properties of natural organic and nanosized macromolecules such as humic substances and proteins are crucial to explore so-called colloid-mediated transport and the fate of substances in soil and water environments. Therefore, the aggregation and dispersion, charging, and floc strength of ly…
Apple due to its climacteric nature lose its quality very rapidly. Chitosan being a non-toxic biodegradable material can be used as coating material for fruits. It would be environmental friendly as compared to other chemicals. Therefore, this experiment was conducted to evaluate the optimum chitosan concentration for…
Abstract The impact of incorporating additional steric restrictions into highly sterically encumbered sulfonated polyaromatic polymers was investigated. Copolymers possessing between 0 and 10% nonlinear ortho or meta biphenyl units in an otherwise linear para biphenyl‐containing sulfo‐phenylated poly(phenylene) were s…
In this article, the high‐temperature (≥1000 °C) oxidation kinetics of porous magnesium‐manganese oxide structures considered for large‐scale thermochemical energy storage are determined. For this analysis, oxides with Mn/Mg molar ratios of 2/3, 1/1, and 2/1 are synthesized via solid‐state reaction and crushed to a po…
Here, we demonstrated the continuous synthesis of metal–organic frameworks (MOFs) (ZnBTeC/MnBTeC/Ni 4 [(phen) 2 (BeTC)]/Co 4 [(phen) 2 (BeTC)]) by using a brand new device—gas–solid two-phase flow synthesis equipment. Quantitative conversions occurred to give products at 60 kg h –1 rates. The single-crystal X-ray diff…
Lateral heterogeneity of a cell membrane, including the formation of lipid raft-like clusters and the inter-leaflet coupling of specific phase domains, is crucial for cellular functions such as membrane trafficking and transmembrane signaling. However, the wide diversity in lipid species and the consequent complexity…
For bottlebrush-type polystyrene polymacromonomer consisting of a polyisoprene main chain and polystyrene side chains (PI-PS-bPM), dynamic birefringence and viscoelasticity measurements were conducted over a wide range of frequencies covering from the glass-to-rubber transition zone to the flow zone. In addition, dyna…
The ternary rare-earth aluminum germanide GdAlGe with tetragonal structure is systematically studied by x-ray diffraction, magnetic and electric measurements. The magnetic and electric properties of GdAlGe are strongly related to its special magnetic structure formed by magnetic Gd3 isosceles triangles △s. The GdAlGe…
The frequency-temperature ( f - T ) characteristic of quartz crystal resonators is an important topic closely related to the frequency-deviation compensation in the design of cost-effective oscillators. Traditional studies depict the f - T characteristic as a polynomial function (usually a cubic function). However, th…
One important natural property of asphalt materials is the ability to self-repair damages. This property could extend service life of asphalt roads and help deter maintenance to some accountable time. This property is basically working on rejuvenating the aged bitumen when cracks appear. With this purpose, two types o…
In this paper, gradual and symmetrical long-term potentiation (LTP) and long-term depression (LTD) were achieved by applying the optimal electrical pulse condition of the interfacial phase-change memory (iPCM) based on a superlattice (SL) structure fabricated by stacking GeTe/Sb2Te3 alternately to implement an artific…
This article presents a method for the computation of the incremental inductances in a 12/10 variable flux reluctance machine (VFRM) using the hybrid analytical modeling coupled with a fixed-point nonlinear solver. The variation of incremental and apparent inductance with respect to the dc-field excitation is investig…
Abstract The radioactive noble gas radon-222 ($\mathrm{^{222}Rn}$) produced in the uranium series is a crucial background source in many underground experiments. We have estimated the adsorption property of Rn with activated carbon fibers (ACFs) in air, argon, and xenon gas. We evaluated six ACFs, named A-7, A-10, A-1…
The effect of the composition on the weight loss of wood protected by a coating based on inorganic and organic substances in the process of thermal exposure, which is a feature of the study of the flame retardant effectiveness of the composition, is investigated. The solution of this problem is carried out by speciall…
Abstract We have fabricated GdBa 2 Cu 3 O y (GdBCO) jointed coated conductors (CCs) using a method in which intermediate grown superconductive (iGS) layers of (Y,Gd)Ba 2 Cu 3 O y ((Y,Gd)BCO) are formed from an YBa 2 Cu 3 O y precursor material to investigate their growth mechanism in the superconducting joint. We char…
Pt Nanoparticles (NPs) are often used as cocatalysts to enhance the photocatalytic hydrogen production catalyzed by the metal organic framework (MOF) materials. The catalytic efficiency of many Pt/MOF systems can be greatly improved when Pt Nanoparticles used as cocatalysts. In this work, the Pt/20%-MIL-125-(SCH3)2 wa…
