The as-cast microstructures of high carbon high speed steels (HC-HSS) made by sand casting, centrifugal casting and electromagnetic centrifugal casting, respectively, were studied by using of optical microscopy (OM) and D/max2200pc X-ray diffraction. The results show that the microstructure of as-cast HC-HSS is domina…
The work deals with evaluation of joint of stainless steel 304 SS (sheet) and commercially pure Ti both after welding explosion and followed-up annealing at 600°C/1.5h/air. The bonding line shows sinusoidal character with curls in crest unlike the trough of the sine curve. The heat treatment does not change the charac…
The solidified structure of the thin-walled and complicated Ti-6Al-4V castings produced by the vertical centrifugal casting process was studied in the present work. The results show that the wall thickness of the section is featured with homogeneously distributed fine equiaxial grains, compared with the microstructure…

Features of the porous ceramics polarization based on the previously developed theory are described. The numerical study of the field remanent polarization depending on the porosity percentage in ACELAN finite element package is presented. The research results are used to model the problem of determining the piezoelec…
We report on how to determine asymmetrical director distribution throughout a liquid crystal layer such as a bistable hybrid-twisted nematic (BHTN) liquid crystal device by means of renormalized transmission spectroscopic ellipsometry. The advantage of the plural oblique incidence spectroscopic ellipsometry (POISE) is…
Abstract Protoglobin from Methanosarcina acetivorans C2A (MaPgb), a strictly anaerobic methanogenic Archaea, displays peculiar structural and functional properties within members of the hemoglobin superfamily. In fact, MaPgb‐specific loops and a N‐terminal extension (20 amino acid residues) completely bury the heme wi…
We compare optical parameters of Ge 2 As(Sb) 2 Se(Te) x ( x = 5, 7) glassy films. Optical gap obtained from transmission and reflection measurements decreases in the sequence Ge–As–Se → Ge–Sb–Se → Ge–As–Te → Ge–Sb–Te similarly to decreasing glass-forming ability of bulk systems. We have found from spectroscopic ellips…
Nanocarbon materials have been expected as post-Cu interconnect materials for large-scale integrated circuits (LSIs). In this paper, we present a nanocarbon deposition process using electroless plated NiB as the catalyst, which features conformal deposition on patterned dielectric surfaces. It was found that carbon na…
A three dimensional (3D) numerical modelling of filament assemblies has been developed in this study. The twist behaviour of the multifilament is simulated using the ABAQUS finite element package by modelling the yarns as 3D continuum elements. The migration of the filaments has been shown in a previous paper. In this…
Electronic energy bands of the Tl-based ternary chalcogenide TlGaTe 2 with a quasi one-dimensional crystalline structure have been studied by means of high resolution angle-resolved photoemission spectroscopy (ARPES) in order to check for dispersive structures similar to the Dirac cone observed in the surface bands of…
Materials scientists at Harvard School of Engineering and Applied Sciences (SEAS) and SiEnergy Systems in Massachusetts have demonstrated the first macro-scale, thin-film solid oxide fuel cell. SiEnergy, which is commercializing the technology, says that scaling up the active area of its nanometric thin-film SOFC is a…
A novel vertical channel phase change random access memory (PCRAM) for application in high-density PCRAM technology with high scalability and small unselected cell current is proposed. The channel of the select transistor and the phase change material are integrated in a vertical structure. A side wall process for the…
According to our previous study, a high concentration of nanoscale tin-doped indium oxide (ITO) may be beneficial for protecting liquid crystal (LC) against attacks by electrostatic discharge (ESD). In this study, the influence of high-voltage stresses in an ESD test was investigated for cells doped with different con…
A collaborative team of six leading research groups from the UK and India has been awarded £1.35 million (US$2.2 million) from the UK Engineering and Physical Sciences Research Council and the Indian Department of Science and Technology, to fund a collaborative three-year research project to model accelerated ageing a…
Damage reduction during planarization is strongly required to avoid scratch generation and the variation in the electrical properties of low- k dielectrics leading to yield loss in an integrated circuit after the implementation of an ultralow- k dielectric in Cu damascene interconnects. An optimum process condition to…

In the UK, ITM Power has announced the sale of its first small-scale bespoke hydrogen production system, to the University of Glamorgan, under a competitive tender process. The proton-exchange membrane (PEM) electrolyzer system will supply around 4 kg of hydrogen per day, based on ITM Power's HFuel® product platform.
To investigate the mechanical behaviour of laminated glass with the elasto-viscoplastic ionomer interlayer SentryGlas® by DuPont, an experimental program was executed on full-scale glass laminates. The results of this research improved the insight in the complex mechanical behaviour of this stiff interlayer. More spec…
