Mechanical, tribological and corrosion properties of metallic materials are of significance to their industrial applications and have been studied for long time. Efforts are continuously made to correlate these properties to more fundamental parameters in order to effectively improve the materials. Electron work funct…
Antireflection coatings are very important elements in several optoelectronic devices, such as solar cells and photo-detectors. In the recent years, various nanostructured dielectric materials have ...

Objective:To study the difference in dissolution behavior of clozapine tablets in four different media between the do-mestic preparations and original preparation to compare the internal quality of the tablets from various manufacturers and provide refer-ence for the drug control. Methods:Referring to the methods of i…
Abstract In numerous systems, giant physical responses have been discovered when two phases coexist; for example, near a phase transition. An intermetallic FeRh system undergoes a first-order antiferromagnetic to ferromagnetic transition above room temperature and shows two-phase coexistence near the transition. Here…

Gas-liquid-solid reactive flows are encountered in many industrial processes. While the transport of reactants and chemical reaction is between gas and liquid phase, solid particles are introduced as catalysts to facilitate the reaction. Major industrial processes where such flows are encountered include alkylation, h…
For centuries, the ability to control light is bounded by the limited range of materials’ refractive index available in nature. This limit is finally broken with the advent of artificially-engineered optical metamaterials. Not only have metamaterials significantly extended the boundaries of refractive index, they have…
Hepatocellular carcinoma(HCC) is the 5th most common malignancy which is responsible for more than half million annual mortalities; also, it is the third leading cause of cancer related death. Unfavorablesystemic side-effects of chemotherapeutic agents and susceptibility to the degradation of small interfering RNAs(si…

AIM:To investigate the interaction between Xiaotan Sanjie(XTSJ) decoction and interleukin-8(IL-8) and its effect on adhesion,migration and invasion of SGC-7901 gastric cancer cells.METHODS:SGC-7901 gastric cancer cells were exposed to serum containing XTSJ decoction and/orIL-8(1 ng/m L).SGC-7901 cell adhesion to fibro…
Waste ethylene propylene diene monomer (EPDM) rubber from postindustrial scrap is significant environmental problem.In attempt to solve this problem, a technology for its recycling and utilization is required.In the present study, the devulcanization of waste EPDM rubber was conducted by means of an ultrasonic twin sc…
Large area uniform thin films of reduced graphene oxide (RGO) was synthesized by pulsed laser deposition (PLD) technique. A number of structural properties including the defect density, average size of sp2 clusters, and degree of reduction were investigated by Raman spectroscopy and X-ray diffraction (XRD) analysis. T…
Two mechanisms of conduction were identified from temperature dependent (120 K–340 K) DC electrical resistivity measurements of composites of poly(e-caprolactone) (PCL) and multi-walled carbon nanotubes (MWCNTs). Activation of variable range hopping (VRH) occurred at lower temperatures than that for temperature fluctu…

Geotextiles are used extensively to protect soil from erosion. In this study, we evaluated the mechanical properties and degradation behaviors of poly(lactic acid)/ poly(butylene adipate-co-terephthalate) (PLA/PBAT) blends. The incorporation of PBAT to PLA decreased the tensile strength and modulus but increased the e…
ii reactions, but the predicted temperature gives an underestimation comparing to the existing experimental data.The d/f orbital charge of R site elements indicate uncorrected rare earth elements could induce certain amount of simulation inaccuracy similar to transition metal elements and the amount of charges in thes…
Composite materials are often produced by pressure-infiltration of a liquid matrix into a preform of packed solid fibers or particles. Capillary forces that intervene in this process are quantified by measuring saturation curves, which are plots of the fraction pore space filled with the matrix versus the pressure dif…
