INTRODUCTION: Collagen is one of the most commonly used biomaterials in scaffold construction for tissue engineering today. The influence of differently organized collagen structures on cellular fates and behaviors is an exciting and interesting area that remains to be explored[1-2]. The objective of this study was to…
The quenching and partitioning or Q & P process concept has been developed over the past few years, as a heat-treatment to produce martensitic microstructures with carbon-enriched metastable retained austenite. The process involves partial martensite formation by controlled quenching, followed by a thermal treatment t…
Although just recently discovered as a superconductor, Magnesium Diboride has already demonstrated its clear potential for an effective use in a variety of applications. With its critical temperature of about 40 K, MgBB2 gives the opportunity to operate devices at cryogenic temperatures of the order of 20 K, allowing…
A high‐speed digital camera was used to observe the deflection‐time history of a Kevlar® fabric to bullet impact. It was observed, as others have, that the deflecting fabric has the shape of a pyramid. The average apex angle of the pyramid was calculated from the digital images and was found to be constant with time f…
SrTiO3 doped ceramics of （1-x）（K0.5Na0.5）NbO3-xSrTiO3 （0≤x≤0.15, （1-x）KNN-xST） were prepared using solid state reaction method and the phase components, crystal structure, and dielectric properties were investigated in this work. It is found that all samples （0≤x≤0.15） are single phases with a perovskite structure wit…
Oil palm shell, a solid waste of palm oil industry in Malaysia was used as a raw material for the production of micro- and mesoporous activated carbons. The chemical activation process with different impregnating agents (65 % zinc chloride, 85 % phosphoric acid and 85 % potassium hydroxide) was conducted at various te…
The solidification of an aluminum-copper alloy has been simulated in 3D using a granular model. Compared to previous similar 2D approaches for where only one phase is continuous, the extension to 3D allows for concurrent continuity of the solid and liquid phases. This concurrent continuity is a key factor in the forma…
The Alsim FEM model which has been applied to aluminum DC casting was applied to the problem of crack formation during vertical direct chill casting of magnesium alloys. The model is a fully coupled thermal stress model. Predictions were compared to crack incidence observed for a variety of cast start speed conditions…
The interaction between liposomes and cells under ultrasound exposure was theoretically and experimentally studied. We experimentally developed liposomes containing fluorescent materials, and measured the efficiency of drug delivery in a suspension containing liposomes and cells under 1 MHz ultrasound excitation for 4…
Development of industrial cell culture processes needs a good engineering practice and system expertise in achieving a successful integrated process using disposable components.The bioreactors for 3D tissues systems could be an advantageous alternative in terms of low contamination risk, easiness of handling and scali…

Considering the plane elastic problem of one-dimensional hexagonal quasicrystals with point group 6mm, the theory about plane strain parallel to aperiodic direction is proposed and established. As an application of this theory, the analytic solutions of elastic fields of the quasicrystals with an elliptical cavity per…
Thin films have become technologically important in recent years.The mechanical properties of a thin film affect its mechanical behavior and may lead to problems such as surface cracking, debonding and buckling.In the literature, nanoindentation tests have been carried out to measure elastic properties and to check pe…
A new energetic material Si‐PETN, having a structure similar to that of PETN, has recently been synthesized (T.M. Klapötke et al., J. Am. Chem. Soc. 129, 6908 (2007)) and shown to exhibit extreme instability that has precluded investigation of its physical and chemical properties by experiment. Although its high insta…

In the present paper，two concepts，“defect degree" and “crystallization potential"，are introduced for evaluating the defects in crystal and describing the potential field near the crystal surfaces，respectively. Based on vast MD simulations of Ni，Cu，Al and Ar crystal growth from different faces at various temperatures，i…
The structural stability and magnetism of Ag atomic chains are studied by the firstprinciples calculations. The chain structures, such as the linear, zigzag, ladder and Tstructure which are formed by three linear chains, are studied. The results show that the linear structure is the most unstable geometry with the l…

The introduction of borate into bio-glass will significantly increase the bioactivity of the glass, as well as increase its biodegradation, which makes the glass being degraded completely. In addition, the toxicity caused by the release of boron from the glass is within the tolerance of human body. So, the attention t…
Molecular statics simulation was used to study the yielding mechanism of 〈100〉 oriented single crystal copper nanowires under tension. The results show that, the yield of nanowires is initially realised via {111}〈112〉 twinning from random activation of partials, and subsequently via slip of {111}〈112〉 partial dislocat…
