This paper describes the use of finite element software to provide a two-dimensional time harmonic analysis of cavitational activity within an ultrasonic cleaning vessel as used within hospitals and dental surgeries. A rational for the simulation method utilized and input parameters affecting the model is discussed. P…
The growing concern of environmental issues is impacting the latest development trends for packaging materials in the semiconductor industry. Several types of brominated flame retardants are used in the electronics industry including PBB (Polybrominated biphenyl), poly brominated diphenyl ether (PBDE) and tetra bromo…
浸炭性ガス雰囲気において“メタルダスティング”とよばれる厳しい腐食が金属材料に発生する．この腐食現象を熱力学的観点から概説した．また，メタルダスティングの防止法として，保護性酸化皮膜の形成と，金属とガスの相互作用について紹介した．
Polycrystalline Sr3CaMn2CoO9 and (Sr0.5Ca0.5)15Mn7Co4O33 have been synthesized and characterised by X-ray and electron diffraction, high resolution electron microscopy and magnetic measurements. These oxides constitute the α = 3, β = 1 and α = 4, β = 1 terms of the homologous series (A3B2O6)α(A3B3O9)β, respectively. I…
Poly(D,L-lactic acid) (P(D,L)LA) is a biocompatible and biodegradable polymer whose use is limited to orthopaedic applications. In fact, the mechanical properties of P(D,L)LA are not usually utilized for cardiovascular applications, as the polymer has been proven to activate both granulocyte- and platelet-causing infl…
Functionalized multiwalled carbon nanotubes (MWNTs) were selected as cross-linkers to construct three-dimensional (3D) porous nanoparticle/MWNT hybrid nanostructures by “bottom-up” self-assembly. The resultant 3D hybrid nanostructure was different from that of metal nanoparticle multilayer assemblies prepared by tradi…
Mechanical reinforcement of an all-sustainable composite, composed of papyrus stem-milled particles as reinforcement and poly-L-lactic acid (PLLA) resin as matrix, was investigated. The papyrus particles (average diameter of 70 μm) could be well dispersed in PLLA resin up to 50 wt% without any surface modification. Yo…
We offer a novel strategy for designing "multi-prong" inhibitors of enzymes by incorporating selective ligands on the liposomal surface.
Biopolymer (polyhydroxyalkanoate, PHA) was extracted and purified from CMG607w bacterial strain isolated from sediment of Layari River outfall to the Arabian Sea. Synthesis of PHA was substrate depended in CMG607w. In the presence of sodium gluconate mcl-PHA was synthesized at the rate of 42% cell dry mass. Under high…
In this study, we selected triglycidyl ether terminated Phenylmethylsiloxnae-co-dimethylsiloxne (GT-1000) which was compatible with the diglycidyl ether of bisphenol A epoxy (DER331) to partial replace the epoxy resin and was cured by liquid anhydride (MHHPA). We also synthesized 5, 5'-(1, 1, 3, 3-tetramethyl disiloxa…
The microstructure and mechanical properties of the Mg97Zn1Y2 alloy prepared by spark plasma sintering of gas atomized powders have been investigated. After consolidation, precipitates were observed to form in the α-Mg solid solution matrix of the Mg97Zn1Y2 alloy. These precipitates consisted of Mg12YZn and Mg24Y5 pha…
Artificial leather used in this study was prepared by wet coagulation method with polyurethane resin in a laboratory instrument. Various needle-punching nonwoven fabrics were used as substrate material, which are widely used in the shoe industry as the substrate of insole or artificial leather. To estimate comfort pro…
In the present study, an automatic production system with sequencer control for the synthesis of carbon nanofibriform based on catalytic CVD using a substrate was developed. The carbon nanotwist (CNTw), which is one of the helical carbon nanofibers, was then synthesized in powdery form with an<mml:math xmlns:mml="http…
This manuscript is a study of precipitation of insoluble drug upon dilution from the pH-cosolvent solubilized formulation with simulated blood fluid. An equation is developed to estimate drug precipitation upon dilution of combined pH-cosolvent solubilized formulations. This is an extension of a previous equation used…
A new chromium free zinc–phosphate–molybdate composite conversion coating on AZ91D magnesium alloy has been developed using an acidic bath mainly containing zinc phosphate, sodium molybdate and sodium fluoride. The examinations of the microstructure and phase compositions reveal that the composite conversion coating i…
For applications such as cooling of electronic devices, it is a common practice to sandwich the thermoelectric module between an integrated chip and a heat exchanger, with the cold side of the module attached to the chip. This configuration results thermal contact resistances in series between the chip, module, and he…
Molecular recognition between two species of Au55 clusters bearing complementary hydrogen-bonding groups provides a facile route to accomplish solution-based assembly of two-component nanoparticle aggregates.
Nano-composites of tin and tin dioxide particles were synthesized on carbon nanotubes by the single-atoms-to-clusters (SAC) method, and their structures were investigated by high-resolution transmission electron microscopy. By changing the heat-treatment temperature during the SAC process, two different types of sampl…
The kinetics of the solid-state polymorphic transition of theophylline anhydrates from the metastable phase (Form III) to the stable phase (Form II) were studied and the effect of humidity on the transition kinetics was quantitatively analyzed. Relative humidity of environments was found to be the major controlling fa…
The heat of wetting of regenerated cellulosic fibres (TENCEL (R), Viscose and Modal) was investigated by reaction calorimetry in comparison with cotton, polyester and TENCEL (R) Fabric. Reaction calorimetry is a technique applied for measuring the heat evolved in chemical reactions where very high analytical precision…
