Polypyrrole-ZnO composites have been synthesized by chemical oxidation method using an anhydrous ferric chloride (Fecl3) as an oxidizing agent for different weight percentages of ZnO. The surface morphology has been studied by scanning electron micrograph (SEM) and structure by X-ray diffraction technique. The SEM ima…
This paper presents an overview of methods for recrystallizing 3-nitro- 1,2,4-triazol-5-one (NTO), with particular emphasis on methods for obtaining spheroidal particles with low porosity. The effects of selected solvents and surfactants on the recrystallization results was checked. Products in the form of spheroidal…
In order to facilitate studies of how dynamically changing element attributes affect the dynamics of the beam and beam losses, the functionality for dynamic kicks (DYNK) of SixTrack has been significantly extended. This functionality can be used for the simulation of dynamic scenarios, such as when crab cavities are s…
A new photoemissive electron source is being built in order to make use of the reduction of ensemble temperature in near band gap photoemission. It will operate at up to 200 kV bias voltage with NEA GaAs photocathodes. High bunch charges will be investigated in pulsed mode with respect to the conservation of emittance…
Drilling quality of medium density fiberboards (MDF) is significantly affected by delamination in furniture industry. The feed generated by a multi-spindle drilling machine tool is the so-called pneumatic pressure which provides a complex non-linear feed. The present study focuses on the machining parameters on delami…
Recently a number of novel drug delivery systems have emerged to minimize drug degradation and loss, to prevent harmful side-effects, to increase drug bioavailability and to achieve controlled and targeted drug delivery. Magnetic microsphere is one of the newer approach in pharmaceutical field due to their biocompatib…
2 Abstract: Fish such as common carp (Cyprinus carpio L), red snapper (Lutjanus sp.) and milkfish (Chanos chanos) play significant role in nutrient sources in Asian countries. The skin constituted of 4% of total body weight is usually discharged. The skin in fact contains of 50% collagen which can be useful as materia…
In this paper, we show how the Ordered Decomposition DAGs kernel framework, a framework that allows the denition of graph kernels from tree kernels, allows to easily dene new state-of-the-art graph kernels. Here we consider a quite fast graph kernel based on the Subtree kernel (ST), and we improve it by increasing its…
Experimental results of effects of thermomechanical couplings occurring in shape memory polymer subjected to tension are presented. Stress-strain curves were recorded by testing machine, while their related temperature changes were measured with infrared camera. The mechanical and thermal characteristics were used to…
Process-induced residual strain causes unexpected shape distortion, leading to premature failure and high manufacturing cost. Cure process simulation is an effective way to optimize the cure process in a reasonable manner. Accurate material properties (i.e., shrinkage strain and elastic modulus change during curing) a…
Various thickness of Zinc telluride (ZnTe) thin films were deposited onto glass substrates in terms of the thermal evaporation technique. The experiments XRD of both powder and thin films of ZnTe showed that the films are polycrystalline and have a zinc blende (cubic) structure. The effect of exposure to the oxygen pl…
Graphene is the most important member of the nanostructured carbon family. The importance of this family of nanostructured materials made it the winner of Nobel Prize in chemistry in 1996. Surprisingly, in 2010, the high potential of the missing piece of the carbon nanostructures puzzle has led it to win the Physics N…
The purpose of this study was to determine the content of glucosamine and chondroitin sulphate of shark cartilage and its use as an anti-aging supplement. It was carried out at the Laboratory of Fish Processing, HangTuah University (HTU), for preparation and isolation of bioactive compounds ; Laboratory of Biochemistr…

Experimentally obtained optimal dosage crystalline glyoxal for use in foam concrete mix. Pictures are taken of the microstructure control samples and samples of the modified foam. It is shown t…
The effect of technical flax fibre fineness, purity and strength on the composite performance was investigated to provide screening methods to assess the composite suitability of the fibres.
The incorporation of sustainability is becoming increasingly important in manufacturing practices worldwide. This includes the development of natural fibre composites with mechanical and flammability characteristics suitable for structural interiors. Composites manufactured from kenaf fibres and polypropylene (PP) wer…
\n\t\t\t\t\tAn approach to achieving the ambitious goal of cost effectively extending the safe operation life of energy pipelines to, for instance, 100 years is the application of structural health monitoring and life prediction tools that are able to provide long-term remnant pipeline life prediction and in-situ pipe…
IrO2-Ta2O5 混合酸化物被覆チタン電極に対して，電極作製時の熱分解温度と前駆体溶液中の金属組成を変化させ，電極作製条件が触媒層構造，特に触媒層の非晶質化に与える影響について検討した。更に，触媒層構造がアノード上における主反応である酸素発生と副反応であるPbO2 電着の抑制効果に及ぼす影響について検討した。電極作製時の熱分解温度の低下，前駆体溶液中のIr 組成の低下により混合酸化物触媒層は非晶質化することが判った。また，触媒層の非晶質化により副反応であるPbO2 電着の結晶化過電圧が増加し，電解時のPbO2 電着の完全抑制を実現した。
The aim of this study was to investigate the feasibility of depositing a thin layer of boron-doped nanocrystalline diamond (B-NCD) on titanium nitride (TiN) coated electrodes and the effect this has on charge injection properties. The charge storage capacity increased by applying the B-NCD film, due to the wide potent…
