Nanostructured ferritic oxide dispersion strengthened (ODS) alloy is an ideal candidate for fission/fusion power plant materials, particularly in the use of a first-wall and blanket structure of a next generation reactor. These steels usually contain a high density of Y-Al-O nanoparticles, high dislocation densities a…
Solenoid actuators are products of mass production.They are applied in large numbers in automotive engineering and industrial automation.Due to the requirement of short development times, a reliable, model-based design process is necessary.To match all those issues, more and more detailed modelling of the actuator has…
A one-phase and/or two-phase method were used to prepare the stable ionic liquid-based nanofluids containing same volume fraction but different sizes or surface states of gold nanoparticles (Au NPs) and their thermal conductivities were investigated in more detail. Five significant experiment parame- ters, i.e. temperat…
An attractive solution to a noise problem in an enclosure is the used of high acoustic performance material. Most panels used nowadays, are variety of man-made mineral fibres which are hazardous to human health. This research provides alternative material used as wall panels from waste. Most waste from natural plants…

Using immunocytochemistry combined with light and electron microscopy, the distribution and ultrastructure of tyrosine hydroxylase (TH)-immunoreactive neurons in the CNS of bivalve mollusc, Megangulus venulosus, have been studied under the influence of increased temperature and hypoxia. It has been established, that t…
Rolling contact fatigue (RCF) is a significant problem in the rail industry as it causes rapid and difficult to detect cracks. Inclusions present in the material can have an adverse effect on the RCF life of rails. This study aims to discover the impact of the loading of rail steel in service on the inclusions present…
A series of novel imidazolium-based crown-type phosphate ionic liquid ultrathin films were fabricated on silicon substrates modified by a self-assembled monolayer. The formation and surface properties of the films were analyzed by means of ellipsometric thickness measurement, X-ray photoelectron spectroscopy, and atomic…
Biological effects of water-soluble inclusion complexes of fullerene C60 with poly(vinyl pyrrolidone) (C60/PVP) and gamma-cyclodextrin (C60/g-CD) as well as solid C60 (C60-coated surface) on cell viability have been studied in vitro. It is established that both inclusion complexes (in a broad range of concentrations)…
In this contribution, monodisperse porous hollow bi-phase gamma-/alpha-Fe (2)O(3) nanoparticles were successfully fabricated based on hard-template method with using carbon colloids as sacrificial templates. A new concept of assembling one kind of metal oxide with different crystalline structures into a single shell w…
Amorphous hydrogenated carbon (a-C:H) films were deposited bymagnetron sputtering with amixture gas of Ar and CH4. The a-C:H films deposited by this method have relatively low internal stress (<1GPa) compared to some films deposited by conventional deposition process. The effects of substrate bias voltage onmicrostructur…
This chapter, based on concepts developed for my book, NanoInnovation (Tomczyk, Nanoinnovation: What Every Manager Needs to Know, 2011), is one of the first attempts to evaluate nanotechnology in the context of the "marketing mix" - a conceptual challenge given that nanotechnology is not one product or even a set of p…
Composite materials are used in a variety of applications being appreciated for their superior properties. However, their use in aggressive environmental conditions, lead to damage and breakage of fibers, matrix fissure, damage of the bond between fiber and matrix. In this respect, the paper presents research on the v…
The teeth of the Polyplacophora Chiton Acanthochiton Rubrolinestus contain biomineralized magnetite crystallites whose biological functions in relation to structure and magnetic properties are not well understood. Here, using superconducting quantum interference device (SQUID) magnetometry, we find that the saturation…
文中以实验技术为手段,研究了不同工况下预载抑制悬浮力弛豫衰减的作用规律.实验以Halbach永磁轨道和三籽晶方形Y -Ba-Cu-O块材组成的系统为主要研究对象,通过改变块材的场冷方式、工作高度、预载高度等,研究这些因素对块材悬浮力弛豫的影响规律.选取30mm场冷高度、15mm工作高度,改变永磁轨道和块材,研究了轨道磁场分布和材料性能对预载条件下悬浮力弛豫行为的影响规律.研究结果表明,不论工况如何,预载后悬浮力的弛豫衰减均被抑制,并且预载高度越低,悬浮力随时间增长越明显,但另一方面,经过预载后悬浮力均出现了不同程度的下降.
Recently, optical technology progress in a wide range of applications, and at the same time, still demands
Microbial metabolism of trans-2-dodecenal (1) was studied. Screening studies have revealed a number of microorganisms that are capable of metabolizing trans-2-dodecenal (1). Scale-up fermentation with Penicillium chrysogenum resulted in the production of two microbial metabolites. These metabolites were identified usi…
The thin films of TiN have been used extensively as wear-resistant materials, for instance, such as tools of high-speed cutting, metal mold forming etc. In these days, because the thin films capable of being used more severe conditions are needed, the technologies of arc ion plating are tried to improve its characteri…
In this study, corrosion characteristics of TiN and ZrN film on the abutment screw by arc-ion plating were investigated using a potentiodynamic anodic polarization test in deaerated 0.9% NaCl solution at . The surface morphologies of the coating layers before and after corrosion test were investigated by a field-emiss…
Generally, ready-mixed concrete(RMC) gets hardened by time, so the remaining concrete in the drum should be cleaned. But if the RMC waste water generated from this is discharged to soil without any treatment, the strong alkaline elements and heavy metals affect water and ecosystem pollution. Although about 10 to 15% o…
