/(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…
We demonstrate that shapes with zero Gaussian curvature, except at singularities, produced by the growth-induced buckling of a thin elastic sheet are the same as those produced by the Volterra construction of topological defects in which edges of an intrinsically flat surface are identified. With this connection, we s…
A new cyclic triterpene saponin, phyteujaposide (1) and eight known compounds (2-9) were isolated from the leaves of Phyteuma japonicum.The structure of the new compound (1) was elucidated by 1D and 2D data analysis, acid hydrolysis and GC-MS.Compounds 7 and 9 potently inhibited the NO production in LPS-activated BV-2…
Selective electron beam melting (SEBM) with an additive-layer thickness similar to 100 pm has been used to fabricate two titanium alloys (Ti-6Al-4V and Ti-6Al-2. 75Sn-4Zr-0.4Mo-0.45Si-0.1Y, designated Ti600 in China) and two TiAl alloys (Ti-48Al-2Nb-2Cr (TiAl), and Ti-45Al-7Nb-0.2W (TiAl-7Nb)). The as-fabricated Ti-6A…
This report describes the production of ERM®-FD102, silica nanoparticles in an aqueous solution certified for different equivalent diameters. The material was produced following ISO Guide 34:2009.\nThe certified reference material (CRM), which has been produced by the Institute for Reference Materials and Measurements…
Ground support for dynamic conditions must be able to withstand the associated loads and deformations and the support scheme has to work as a system. In order to prove the suitability of such support systems with mesh and bolts, and to also analyse the bearing behaviour of them, a full scale test setup was commissione…
Telah dilakukan penelitian tentang pembuatan dan karakterisasi sifat mekanik bahan komposit serat daun nenas-polyester ditinjau dari fraksi massa dan orientasi serat. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan massa serat terhadap sifat mekanik pada komposit resin polyester khususnya kuat tarik dan…
Barium and Zinc doped CdS thin films were deposited by simple and easy spray pyrolysis method at 400°C. The crystallographic structure and the crystallite size were studied by the X-ray diffraction (XRD) pattern. Optical band gap were studied by optical absorption spectroscopy and electrical measurements by means of e…
This chapter presents statistical evaluations of script relics. Its concept is exploiting mathematical statistical methods to extract hidden correlations among different script relics. Examining the genealogy of the graphemes of scripts is necessary for exploring the evolution of the writing systems, reading undeciphe…
A novel technique for glucose sensing using collagen based thin film and zinc oxide (ZnO) nanoparticles, the Zinc Oxide Collagen Glucose Sensor (ZnOCGS) presented here. The Zinc oxide is synthesized using the two medium namely treating with 1.Ethanediol medium (Ethylene glycol) and 2.Water medium. It is characterized…
Two newly synthesized water-soluble conjugates of Paclitaxel with malonodiserinolamide-derivatized [60]fullerene (C60-ser) undergo hydrolysis and release their medical payload under biological conditions. In vivo testing of one of these compounds in a murine model showed tumor volume reduction similar to the FDA-appro…
To measure temperatures by microbolometer-based infrared cameras one has to deal with disturbing radiation flux due to the ambient temperature derived from the interior of the camera enclosure. The standard approach determines this radiation flux by using an optical shutter occasionally and subtracting the derived cor…
In this study, we report on the acid-catalysed synthesis of La(9.33)Si(6)O(26) from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline phases. The similarity of the Fourier transform infrared spectra of the lanthanum-salt soluti…
Abstract The photocatalytic degradation of three common indoor VOCs – acetone, toluene and heptane – is investigated in a dynamic photocatalytic oxidation loop using Box–Behnken designs of experiments. Thanks to the experimental results and the establishment of a kinetic rate law based on a simplified mechanism, a pre…
The effect of Mn addition on a brittle-to-ductile transition (BDT) in Ti added ultra-low carbon steels was investigated comparing with the effect of Ni on it. The effects of Mn on the temperature dependences of 0.2% proof stress, activation volume and effective stress in Ti added ultra-low carbon steels were nearly th…
Beginning as early at the 1930s, scientists were able to see at the nanoscale using instruments such as the scanning electron microscope, the transmission electron microscope, and the field ion microscope. The most recent and notable developments in microscopy are the scanning tunneling microscope and the atomic force…
Surface patterning of p-GaN to improve the light extraction efficiency of GaN-based blue light-emitting diodes (LEDs) has been investigated. Periodic nanopillar arrays on p-GaN have been fabricated by polystyrene (PS) nanosphere lithography; the diameter of the nanopillars can be tuned to optimize the electrical and o…
