Microstructures of three types of YBa/sub 2/Cu/sub 3/O/sub 7- delta / single crystals having strong differences in their j/sub c/ levels have been studied by means of electron microscopy. In order to find any existing relation between the microstructures a ...
Dendrite tip temperature measurements are reported for the hypereutectic alloy Al-30% Si, directionally solidified as a bulk (non-composite) alloy, and also as the matrix of a fibrous metal matrix composite. Over the range of tip velocities studied (10-100 ...
The authors have investigated the transmission properties and defect characteristics of layer-by-layer metallic photonic crystals. Thay have demonstrated experimentally that the metallicity gap of these crystals extends to an upper band-edge frequency, and ...
We present a novel method for the fabrication of well-ordered, two-dimensional nanocluster arrays. The method is based on the confined nucleation of adatoms within the superstructure cells of periodic surface dislocation networks, which form in many hetero ...
BACKGROUND: We present the synthesis, characterization and initial structure-function analysis of a new class of bioactive agent that allows the application of techniques from colloid science to biological surfaces. Stable colloidal suspensions can be gene ...
The photoelectrochem. properties of colloidal film electrodes are compared with solid transparent thin films of TiO2. In particular the information that can be derived from anal. of the action spectra for front and back side illumination of the films is gi ...
The dislocation structures resulting from compression tests on Ni-3 (Al, I-If) single crystals are studied as a function of the deformation temperature between 77 and 900 K. Mechanical parameters are also reported, such as the 0.2% offset stress, the work- ...
Physisorbed and covalently bound Langmuir-Blodgett (LB) monolayers of sulfur-bearing lipids on mica and on gold substrates, resp., have been studied. Scanning force microscopy, in topog. and friction modes as well as in contact and non-contact modes have b ...
Charge sepn. in sintered colloidal TiO2 film electrodes was studied by action spectra in SCN-/(SCN)2- the UV region. Electrodes with different film thicknesses were studied. Current generation is most efficient close to the back contact. Monochromatic quan ...
A review with 156 refs. on interfacial electron transfer reactions in colloidal semiconductor solns. and thin films and their application for solar light energy conversion and photocatalytic water purifn. Some of the topics discussed include; optical and e ...
