The use of synchrotron radiation (SR) based X-ray absorption spectroscopy (XAS) and X-ray in-duced photoelectron spectroscopy (XPS) is demonstrated for the analysis of thin films. In the first part we report on oxidic films used for high-k dielectric films in Si technology and focus on a recent in-situ ap-proach to st…

AP5346 (Prolindac ™ ) is a macromolecule consisting of a biocompatible and water soluble polymer to which a DACH-Pt is bound via a pH-sensitive chelat-ing group. It was rationally designed to increase delivery of the DACH Pt moiety to tumors by taking advantage of the increased permeability of tumor capillaries. Studi…
SETIA UTAMI DEWI. Synthesizes of Calcium Phosphate-Chitosan Composite by Sonication Method. Under direction of KIAGUS DAHLAN and DJARWANI SOEHARSO SOEJOKO. Formation of biomaterial composite consisting of organic matrix and inorganic mineral has been studied. The inorganic minerals used hydroxyapatite and hydroxyapati…
Essential oil from Artemisia herba alba (Art) was hydrodistilled and tested as corrosion inhibitor of steel in 0.5 M H2SO4 using weight loss measurements and electrochemical polarization methods. Results gathered show that this natural oil reduced the corrosion rate by the cathodic action. Its inhibition efficiency at…
The conidia of aquatic hyphomycetes were discovered by C.T. Ingold some 60 years ago. They are typically multiradiate or sigmoid, relatively fragile, and produced in enormous numbers. Their main function seems to be the rapid colonization of a periodic superabundance of leaves common in most streams. Conidia are unlik…
Turn milling is an innovative production technique for the precise manufacture of axially symmetric geometric features. The generation of high quality surfaces by means of machining aluminium matrix composites (AMCs) demands detailed knowledge of significant influencing variables. On the basis of extensive research in…
A gram-positive bacterium that accumulated PHB was isolated from local garden soil in Bangalore. Based on its morphological and physiological properties, and nucleotide sequence (about 1.5 kb) of its 16S rDNA it was identified as Bacillus thuringiensis IAM 12077. In this study the PHB-producing capacity of putative mu…
K-shell fluorescence yields \omega_K were measured for the elements Ti, V, Cr, Fe, Co, Ni, Cu and F and Cl compounds of these elements. Measurements were carried out at 10 keV excitation energy using secondary excitation method. K x-rays emitted by samples were counted by a Si(Li) detector with 160 eV resolution at 5.…
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters. In this study, periphytic algae collected in situwere exposed under controlled con…
Persistent tetrodotoxin-resistant (TTX-R) Na+ (Nav1.9/SCN11A) currents are not normally recorded in vagal afferent neurons (VANs) with 50 mM of extracellular Na+ although the functional expression of this current was observed in the presence of PGE2 or forskolin. However, it is uncertain whether this current can be se…
We report observation of optically pumped multi-directional lasing at visible wavelengths from dye-doped three-dimensional icosahedral quasicrystals fabricated in dichromate gelatin emulsions using a novel seven-beam optical interference holographic method. The lasing pattern exhibits icosahedral symmetry.
Aluminumtriethoxide were obtained when aluminum powder was refluxed in dehydrated ethanol containing aluminum chloride for 10 ks. It is shown that aluminumtriethoxide powder made in our laboratory coincided with that supplied in commercial market by similar pattern of XRD-analysis, particle size distribution analysis…
It was found that aluminum alkoxide reaction of aluminum alloy 6063 occurs in ethyl alcohol containing aluminum chloride. The reaction is explained by the superimposition of Al/Al3+ reaction as the anodic reaction and ethanol/ethylate reaction as the cathodic reaction. In an environment containing chloride ions, an Al…
The effect of oxide inclusion compositions on microstructure and notch toughness of weld metal for HT780MPa class high strength steel was investigated. Three different types of weld metals were prepared by varying deoxidant elements. Intragranular bainite microstructure and dispersed oxide inclusions were observed and…
Carbon nanotube is scientifically quite interesting material because of its structural feature and various new quantum transport properties. By applying the feature of the narrow wire structure, the high sensitive bio sensor becomes possible. In the present paper, the specific quantum transport in carbon nanotube, and…
The excess thermodynamic quantities of lanthanides and actinides in molten salts and liquid metals were studied for reductive extraction of minor actinides. The excess enthalpies and entropies of those elements in the molten chloride phase were found to be correlated with the ionic radii of metal ions possibly due to…
To satisfy the requirement in blisk machining, a barrel-ball milling (BBM) cutter suitable for machining both blade and hub is presented in this paper. The selection of cutter parameter and calculation of cutter location were put forward. The new efficient machining cutter location via the advanced optimization on cut…
We have studied the solid to liquid-crystalline phase transition of sonicated vesicles of dipalmitoylphosphatidylglycerol and dipalmitoylphosphatidylcholine. The transition was studied by both fluorescence polarization of perylene embedded in the vesicles, and by the efflux rate of trapped 22Na+.Fluorescence polarizat…
The reactivity worth of 22.87 grams of 237Np oxide sample was measured and analyzed in seven uranium cores in the Tank-Type Critical Assembly (TCA) and two uranium cores in the Fast Critical Assembly (FCA) at the Japan Atomic Energy Agency. The TCA cores provided a systematic variation in the neutron spectrum between…
