Three hardwoods of varying vessel arrange- ment were treated with the ionic liquid, 1-ethyl-3-methyl- imidazolium chloride ((C2mim)(Cl)), which can dissolve cellulose, to investigate its influence on wood tissue mor- phology. Characterization was carried out by light and scanning electron microscopy. The wood fibers o…
Micro-plates of micron-size length, width and thickness are widely used in micro-electro-mechanical systems(MEMS), therefore, the analysis on the vibroacoustic characteristic of micro-plates is of paramount importance to ensure the stability of MEMS under acoustic excitation and the accuracy of acoustic sensors. The v…
A new ligand 1-carboxymethyl-5-methyl-1H- pyrazole-4-carboxylic acid (H2L 1 ) and its isomer 1-carboxy- methyl-3-methyl-1H-pyrazole-4-carboxylic acid (H2L 2 )h ave been synthesized and characterized by IR and 1 HN MR. Three complexes of these ligands, (M(HL 1 )2(H2O)2 )( 1 :M = Zn; 2: M = Cu) and (Cd(HL 2 )2(H2O)2 )(…
Fe5O7(OH)4H2O ferrihydrite is a low-crystallinity antiferromagnetic material.c-Fe2O3(maghemite)magnetic nanoparticles were prepared from a ferrihydrite precursor,by chemically induced transformation in FeCl2/NaOH solution.The magnetization,morphology,crystal structure and chemical composition of the products were dete…
Glucose oxidase(GOx) was immobilized on the electrode surface of multi-walled carbon nanotubes, amino functionalized carbon nanotubes(AMWNTs) and carboxyl functionalized carbon nanotubes(MWNTs-COOH). Electrochemical measurements indicated that the formal potentials of GOx immobilized on AMWNTs and MWNTs-COOH did not c…
In this paper, we purpose a two dimensional photonic crystal based optical sensor for salinity measurement. The salinity percentage of is sea water changes as we go down the sea water surface. This gives change to the index of refraction of the sea water at the different levels. Thus the salinity percentage of sea wat…
