Tissue engineering involves the removal of cells from the patients which is seeded onto a scaffold for cell growth and regeneration. The scaffold serves many functions, such as providing structural support and chemical stimuli for cell proliferation for the implanted cells. Ideally, the scaffold should be three dimens…
Gold nanorods can be synthesized by a photochemical approach. In this report, a mixture solution of HAuCl4, TiO2, HCl and ethanol was irradiated by a halogen light source. Ethanol reduced Au3+ to Au0 upon light irradiation. The TiO2 acted as both catalyst and stabilizer. TiO2 has a large band gap, which enables it to…
AnotaceParovodní systémy výtopen, tepláren a kondenzačních elektráren se koncipují tak, že napájecí voda (směs přídavné vody a kondenzátu ) se dopravuje napájecími čerpadly přes ohřívák vody (ekonomizér) do kotlové části parního kotle.V ohříváku vody dochází při nesprávné funkci odplynění napájecí vody k intenzivní ko…
In this study, the synthesis of luminescent functionalized hydroxyapatite (HA) was investigated. Rare earth metal ions such as ytterbium (Yb3+) and erbium ions (Er3+) were doped into HA via the hydrothermal synthesis method. Fluoridated HA (FHA), achieved by exchanging hydroxyl ions in doped HA with fluoride ions via…
The unique advantage of neutrons as biological probes is the ability to visualize hydrogen atoms in macro-molecules. In this issue, Kovalevsky et al. (2010) solved an ensemble of xylose isomerase structures byneutron crystallography, and the determination of hydrogen atom rearrangements during the catalytic cycleprovi…
This project is a continuation of a previous student’s final year project. As a reference to begin with, the author was handed the “F-16 Non-Jettisonable Fuel Pylons Flight Loads Instrumentation and Calibration Report CCP5883” report produced by General Dynamics in 1984. According to the RSAF, the pylons were calibrat…
The authors summarise available literature and own data concerning the use of monoclonal antibodies raised against neurospecific proteins in medical nanobiotechnologies of targeted delivery of diagnostic and therapeutic agents across blood brain barrier. Presented are the results of preclinical trials of cell specific…
Research was conducted to investigate the effect of chemical functional groups, including the ether function and alkyl branches, on the biodegradation mechanisms and biodegradation rates of dibenzoate plasticizers.Biodegradation of 1,6-hexandiol dibenzoate, a potential green dibenzoate plasticizer, by Rhodococcus rhod…
Polyethylene composites reinforced with glass fibers and elastomer-toughened with styrene-ethylene-butadiene-styrene were prepared using extrusion and then compression molded to form tensile bars conforming to the ASTM D-638 testing standards. Varying amounts of glass fibers and SEBS elastomers were incorporated into…
На основании электронно-микроскопических исследований слоистых пленочных систем эвтектического типа Ge-Au построена размерная зависимость температуры кристаллизации жидкой фазы эвтектического состава в контакте с аморфной германиевой подложкой. Измеренный угол смачивания и величина переохлаждения жидкой фазы в системе…
It was gathered from various studies that bimodal fibers are beneficial for cell behavior. By electrospinning thin Poly-ε-caprolactone (PCL) fibers on Selective Laser Sintering (SLS) scaffold, a similar bimodal effect of having both large and small size fiber diameters is achieved. The bimodal scaffold is then stacked…
Se75S25-xCdx is a promising ternary material, which has received considerable attention due to its applications in the fabrication of various solid state devices. These have distinct advantages, large packing density, mass replication, fast data rate, high signal-to-noise ratio and high immunity to defects. Measuremen…
2010年3月，ChinaJoy组委会对外宣布，第八届ChinaJoy将在世博举办期间的2010年7月29日～8月1日举行，展会同期将举办“第八届中国游戏商务大会（China Game Business Conference，CGBC2010）”、“第三届中国游戏开发者大会（China Game Developer Conference，CGDC2010）”以及“首届中国游戏外包大会（Chlna Game Outsourcing Conference，CGOC）”。
The traditional passivation processes, standard RCA cleaning and 1% HF aqueous solution immersion, were introduced to passivate the surfaces of p-type Si(100) wafers for heterojunction with intrinsic thin-layer (HIT) solar cell application. The passivation stability was checked by monitoring the time decay of the effe…
Chloroprene rubber (CR)/organic modifier/sodium montmorillonite (NA-MMT) nanocomposites were prepared by melt intercalation. The morphology of the nanocomposites was studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM). TEM results showed that the silicate layers of the clay were dispersed…
This project aims to quantify the rate of copper de-layered during Chemical Mechanical Polishing for semiconductor devices. This is to improve the effectiveness of de-layering copper during failure analysis since copper is prone to smearing, erosion and dishing. The report is generally divided into three parts. The fi…
