A study on the diversity of benthic diatoms and water quality of the Ping River, Northern Thailand were carried out from December 2004-December 2005. Samples were collected from 15 sites covering the whole river. The water quality was based on specific physical and chemical factors indicated the water in the Ping Rive…
It have been studied the structure, phase composition and the specific surface of alumina-based powder systems produced by the method of thermal decomposition of hydroxide aluminum and the plasma-spray pyrolysis method. It was shown that in the plasmochemical powder there is a sharp transition to the -form in a narrow…
Nystatin and Terbinafine are antifungal drugs with well-known antifungal properties. In the present study we investigated the potential of PAMAM and PPI dendrimers of different generations as tool for enhancement of antifungal activity of selected two antifungal drugs. Microbilogical study showed that PAMAM and PPI de…
The efficacy of an acid extract of leaves of Sida rhombifolia.L as corrosion inhibitor for mild steel in 1M phosphoric acid medium, was carried out using weight loss measurements, polarization and electrochemical impedance spectral studies. Experiments are performed by varying immersion period, concentration of the in…
The aim of the present work was to evaluate the stress corrosion cracking (SCC) behavior of the annealed Al-7075 alloy before and after Equal Channel Angular Pressing (ECAP). The SCC behavior of the Al-7075 alloy before and after ECAP was evaluated using slow strain rate testing (SSRT). Tensile and SCC behavior of the…
Partly ordered Fe3Pt is one of ferromagnetic shape memory alloys exhibiting a large magnetic field-induced strain in its martensite phase formed by a second-order-like martensitic transformation from the L12-type structure to the so-called FCT martensite (L60-type structure). We have investigated the origin of this tr…
Hard sphere crystal growth is a delicate interplay between kinetics and thermodynamics, where the former is commonly thought to favour a random hexagonal close packed structure and the latter leads to a face centered cubic crystal. In this article, we discuss the influence of slanted stacking faults on the growth of s…
A vapor phase based silylation process was used to restore plasma damaged porous ultra low-κ SiOCH dielectric films. The process was carried out with 11 different silylation agents. After the processing of blanked wafers, the restoration performance was analyzed by different analytic techniques such as Fourier infrare…
In the present work, we have designed a simple and original procedure for the spontaneous formation of macroporous organosilica films by photopolymerization-induced phase separation, avoiding the intervention of a template. The simple mixture of 3-(glycidyloxypropyl)trimethoxysilane (CH3O)3Si(CH2)3OCH2-CHCH2O (GPTMS),…
The functionality of metal-doped carbon materials in catalytic and hydrogen storage applications is governed by the characteristics of their interaction with hydrogen. The dynamics of hydrogen chemisorption, its migration and desorption are investigated by first-principles molecular dynamics simulations of a model Pd4…
A sensitive and practical colorimetric test for oxidized carbon nanotubes (CNTs) is described. The assay is based on direct labeling with the commercially available fluorescent dye thionin acetate (THA). This strategy offers the possibility for quantitation of acidic sites in a very fast and easy way.
Tetrairon(III) complexes with a propeller-like structure derived from [Fe(4)(OMe)(6)(dpm)(6)] (1) (Hdpm = 2,2,6,6-tetramethylheptane-3,5-dione) are providing a growing class of Single Molecule Magnets (SMMs) displaying unprecedented synthetic flexibility and ease of functionalization. Herein we report the synthesis, c…
This paper reports the layer-by-layer synthesis and growth kinetics of a new class of nanostructured multilayers consisting of montmorillonite (MMT) nanoclays “glued” by sol–gel oxides, such as zirconia (ZrO2) and tin oxide (SnO2), {MMTx-(sol–gel oxide)}n. The multilayers possess an ordered layer structure with tunabl…
Absorbance spectra of gold nanoparticles synthesized by deposition of an ultrathin gold film on fused silica substrate with electron-beam evaporation followed by rapid thermal annealing have been obtained from spectrophotometry measurement. The surface plasmon resonance wavelength can be tuned by controlling the synth…

Abstract—In the framework of the Green function method, we theoretically study the photonic band structure of one-dimensional superlattice composed of alternating layers of right-handed and lefthanded materials (RHM and LHM). The dispersion curves are studied by assuming that the dielectric permittivity and magnetic p…
Polymers such as ethylene-vinyl acetate (EVA) encapsulants are known for their non-linear mechanical material behavior. We identify the time and temperature dependence of EVA with the help of dynamic mechanical analyses (DMA) and relaxation/creep experiments. Mechanical investigations of PV modules that address the is…
A highly soluble perylenediimide (PDI) dye with unusual polyhedral oligomeric silsesquioxane (POSS) molecules was synthesized by the reaction of an aminopropylisobutyl POSS (POSS-NH2) and 3,4,9,10-perylenetetracarboxylic dianhydride in the presence of Zn(OAc)2. This material exhibits good thermal stability and high fl…
The mononuclear Re(IV) compound of formula (PPh(4))(2)[ReBr(4)(mal)] (1) was used as a ligand to obtain the heterobimetallic species [ReBr(4)(μ-mal)Co(dmphen)(2)]· MeCN (2), [ReBr(4)(μ-mal)Ni(dmphen)(2)] (3), [ReBr(4)(μ-mal)Mn(dmphen)(2)] (4a), [ReBr(4)(μ-mal)Mn(dmphen)(H(2)O)(2)]·dmphen·MeCN·H(2)O (4b), [ReBr(4)(μ-ma…
We report on a study of the formation of crystalline copper and nanocrystalline cuprous oxide at electrochemically prepared mesoporous silicon surfaces immersed in a copper sulfate solution.
