In the Nuclear Science Research Institute, Japan Atomic Energy Agency (JAEA), in order to oxidize 14C, which exists in various chemical forms in exhaust, into 14CO2, a copper oxide (CuO) catalyst is introduced after heating to 600℃. Our goal was to establish a safer 14C monitoring system by lowering the heating temper…
The thermal profile of a directionally solidifying single crystal (SX) turbine blade was simulated using finite element technique. The result showed that profile in the platform is wave-shaped rather consistent concave. Such a distributed thermal profile forms an isolated thermal undercooling zone in the platform end…
In the present study, doxorubicin (DOX)-loaded poly (ε-caprolactone) (PCL) nanoparticles were formulated using the nanoprecipitation technique and their physicochemical properties were evaluated. The size of the nanoparticles was found to be 338-472 nm. The percentage yield obtained was 85.1%-87.8% while the percentag…
A novel thermosensitive luminescent lanthanide coordination compound was successfully synthesized. The coordination compound consists of Eu, Tb, and two photosensitized organic ligands [hexafluoroacetylacetone (hfa) and tris(p-carboxyphenyl) phosphine oxide (TPO)]. The Eu/ Tb mixed coordination compound shows differen…
The models of sulfide minerals (covellite, bornite, chalcopyrite and pyrite) are developed. The molecular models of thionocarbamates containing electron-accepting (O-butyl-N-ethylcarbamothioate (BETC)) and electron-donating (O-butyl-N-benzoylcarbamothioate (BBTC)) radicals bonded to nitrogen atoms are built. The inter…
Heat treating is what gives metals its hardness as well as its toughness, wear resistance and ductility.Even performed properly, heat treating cannot remove all of the retained austenite (large, unstable particles of carbon carbide) from steel.Proper heat treating is a key part in increasing a part's toughness, durabi…

UK-based Ceres Power has signed a new Joint Development Agreement with Honda R&D Co Ltd in Japan, to jointly develop solid oxide fuel cell stacks using Ceres Power's unique intermediate-temperature, metal-supported Steel Cell technology for a range of potential power equipment applications.
In the present work we investigate the creep behavior of a single crystal superalloys (SX), using precisely oriented miniature tensile creep specimens. We study the single crystal superalloy ERBO/1 (CMSX-4 type) in the temperature range between 1023 and 1323 K. We investigate how creep rates evolve in different stress…
Carbon nanotubes (CNTs) have been central materials in the field of nanotechnology and nano-materials science due to their remarkable physical, physicochemical, thermal, mechanical and electrical properties. One of the key issues in the utilization of such seminal materials for basic researches together with the mater…
A personal selection of 33 recent papers is presented covering various aspects of current developments in bioorganic chemistry and novel natural products such as pseudellone A from Pseudallescheria ellipsoidea .
The present work [1] aims to reveal the effects of solute atoms (TM=Ag, Zn and Zr) on the age-hardening of Mg-Gd-based alloys via the density functional theory and electron work function (EWF) approaches. Based on the electronic structures of LPSOs (including 6H, 10H, 14H, 18R and 24R) [2], the 10H LPSO phases of Mg-G…
Photoluminescence-based nanomaterial sensors doped with rare-earth elements have a potential for use in sensitive, portable, and low-cost detectors.The oxide with the formula XY 2 ZO 5 has potential for fluorescence applications because of its orthorhombic structure, stable physical and chemical properties, and high t…
Metal organic chemical vapor deposited GaN thin films on n-Si (111) substrates with cubic -SiC (c-SiC) and porous -SiC (PSC) buffer layers were characterized and compared with each other. We used rapid thermal chemical vapor deposition (RTCVD) to grow the c-SiC layers, and some of them were electrochemically anodized…

The study worked out an efficient optimization of heat fusion conditions between thermoplastics using molecular dynamics (MD) and a response surface method. The heat fusion process between polypropylene (PP) and polyethylene (PE) and the uniaxial elongation for evaluation of the interfacial bonding strength were model…
Oxidation of graphite produces graphite oxide and/or graphene oxide, both of which are abbreviated “GO”. The preparation methods of these materials have been described by Brodie, Staudenmaier, and Hummers. Graphene oxide is widely recognized as a promising material in various fields, but its structure and composition…
Polyvinylidene fluoride (PVDF) piezoelectric nanofibers were fabricated through near-field electrospinning (NFES) to develop a flexible piezoelectric element. Innovative screen printing technology was employed to produce bend-type electrodes designed with d 33 mode patterns. The electrodes and PVDF nanofibers were the…
This review paper describes the etching behavior of various carbon materials by metal nanoparticles (cobalt, nickel or platinum) in a flowing gas mixture of hydrogen and nitrogen (1 : 9) between 700 °C and 1000 °C based on our earlier studies. This study started from the observation of the etching of a carbon black (C…
