The nanoscopic deformation behaviors in a ZrCu metallic glass model during loading‐unloading process under uniaxial compression have been analyzed on the basis of the molecular dynamics (MD). The reversible degree of shear origin zones (SOZs) is used as the structural indicator to distinguish the elastic deformation a…
Crystal structure of the first homochiral luminescent compound of a dansylated amino acid (tyrosine) of Cu( ii ), [Cu 2 (HTyr- N -Dan) 4 (H 2 O) 2 ]·2H 2 O ( 1 ) (H 2 Tyr- N -Dan = N -dansyltyrosine), and selective sensing of nitroanilines by both the ligand and 1 are reported.
Complex chemical compounds found as minerals or synthesized in labs evidenced a multi-shell structure. Also, fullerenes aggregate, randomly or following a well-defined geometry, in multi-shells. The way of space filling differs as a function of the dimensions and shape of the composing small cages. In this paper an at…
Li 3.33 Cu 1.005 Ti 4.665 O 12 with P 4 3 32 space group composited with CuO was fabricated and exhibits a small potential hysteresis and high rate performance.
The heat of reaction for the decomposition of polyurethane foam and its melt are determined from the heat flow measurements obtained through simultaneous differential scanning calorimetry and thermogravimetric analysis. Under nitrogen environment, the decomposition of foam experiences two endothermic pyrolysis reactio…
Biochar is getting momentous importance due to its potential use in various fields like agriculture, organic fertilizers and green house gas (GHG) sequestration. The mineralization of biochar in soil is greatly dependent upon the temperature and moisture level of the soil, therefore under simulated ecological conditio…
Friction stir process (FSP) and post thermal exposure were carried out to a microstructure-thermostable cast Al–5Mg–0.5Mn alloy to examine the grain size dependence of tensile yield stress by using Hall–Petch relation, σy = σ0 + kyd−1/2. The measurement of preferred crystalline orientations and grain boundaries charac…
Helicobacter pylori are the causative agents of gastroduodenal disorders, such as peptic ulcer, acute gastritis and even stomach cancer. It is believed to infect over half the world’s population. Recently, there have been cases of chemotherapy – failures and emergence of resistant strains. This necessitated the search…

The drying of crushed oil palm fronds was studied in a fluidized bed dryer assisted with mechanical agitation at different inlet air temperature, superficial air velocity, bed loading and agitation speed. The drying kinetics of the fibers under various drying conditions could be described by a single characteristic dr…
This paper describes the design of the “Spotter” unmanned aerial vehicle, developed by the University of Southampton as part of the 2SEAS-3i European Interreg project. Spotter is a twin engine, 4m wing span, fixed-wing aircraft which has been designed to perform long-endurance, all-weather patrol missions in coastal a…
Recent success in restoring visual function through photoreceptor replacement in mouse models of photoreceptor degeneration intensifies the need to generate or regenerate photoreceptor cells for the ultimate goal of using cell replacement therapy for blindness caused by photoreceptor degeneration. Current research on…
189 INTRODUCTION Materials scientists and clinicians worldwide are working to improve the performance of dental implants, with the aim of accelerating and maintaining integration into hard and soft tissues, and extending their range of application. The surface characteristics of the implant material affect the rate an…
The results of pilot plant investigations of simultaneous removal of NO x , SO 2 and Hg from flue gas with ozone as the oxidizing agent and the spray tower absorber with NaOH solution as the absorbent have been presented. Flue gas was delivered into the pilot plant at the flow rate of 200 m 3 /h from the coal fired OP…
Solid dispersion is one of the most widely used methods to enhance the solubility and dissolution rate of poor water soluble drugs. In the present study, flurbiprofen solid dispersions were prepared using solvent evaporation method by incorporating polyethylene glycol 20000 and evaluated for solubility studies, drug-c…
Phase Change Memory (PCM) is a promising DRAM replacement in embedded systems due to its attractive characteristics such as extremely low leakage power, high storage density and good scalability. However, PCM's low endurance constrains its practical applications. In this paper, we propose a wear leveling aware dynamic…
In recent years, all-optical diodes based on photonic crystal heterostructures have attracted much attention, and their good characteristics of one-way transmission are the long pursued target. In this paper, different optimized designs are proposed by modifying the photonic crystal structure at the heterostructure in…
INTRODUCTION: The newer technologies are developing in pharmaceutical field. The most efficacious dosage forms are generated on already existing molecules because many hurdles occur during discovery of the new molecules . Pulsatile drug delivery system is gaining a lot of interest and attention now a day. Though most…
/(Nm) 然后涨了。composites 的 wear 机制主要是粘合剂穿由磨料伴随了在更低的正常负担和滑动速度穿。然而， composites 的 wear 机制是磨料穿并且粘合剂在 wear 过程期间由于表面和表面下的裂缝的成核和繁殖在更高正常的负担和滑动速度象分层一样穿。像薄片、像粒子穿碎片碎片的主导的形状被观察。
Metal foams are a very interesting class of microheterogene ous, cellular, lightweight materials which are often used as kinetic energy absorber. In this study open cell meta l foams consisting of a 3D network of interconnected pores have been coated with nanocrystalline nickel via an el ectrodeposition technique. The…
