We illustrate the propagation of light in a new type of coupling mask for lensless optical lithography. Our investigation shows how the different elements comprising such masks contribute to the definition of an optical path that allows the exposure of fea ...
DSA type electrodes (IrOx/Ti) were prepd. by induction heating technique which allows a rapid decompn. of the precursor under anaerobic conditions. With this type of electrode, an activation process is obsd. in cyclic voltammetry which can be related to th ...
The solid state structure of h5-2,5-di-(t-butyl)phospholylgallium(I) 1 was detd. by x-ray diffraction at 190 K. The mols. of 1 are partly organized in a new type of structure: a Ga zigzag chain in which the arom. phospholyl rings alternate on both sides of ...
A low weight resistant porous glass fiber of type I is disclosed with a developed specific surface area of 5 times to 120 times the outer surface of a standard glass fiber, and a material having physical, chemical or biological reactive properties deposite ...
An algorithm for connection admission control (CAC) in the case where connections are of the variable bit rate (VBR) type and the trunk carrying the multiplexed VBR connections is itself a VBR connection. ...
Mutations of the glycoprotein rBAT cause cystinuria type I, an autosomal recessive failure of dibasic amino acid transport (b(0,+) type) across luminal membranes of intestine and kidney cells. Here we identify the permease-like protein b(0,+)AT as the cata ...
The light-induced degrdn. of Tinopal DMS-X, a stilbene type fluorescence whitening agent (FWA) which is quite resistant to biodegrdn., is described. This substance has been chosen for the study of the titania-induced degrdn. of polycyclic stilbenes since i ...
In Al0.3Ga0.7As/GaAs quantum wells bordered by ultrathin (one or two monolayers) AlAs layers, the AlAs layer has been shown to provide a well for electrons at high pressure [Phys. Rev. B 45, 11 846 (1992)]. In this work, the same type of structures but gro ...
Putative intersubunit electrostatic interactions between charged amino acids on the surfaces of the dimer interfaces of leucine zippers (g-e' ion pairs) have been implicated as determinants of dimerization specificity. To evaluate the importance of these i ...
The title bed is developed with in situ cryst. growth of zeolite ZSM-5 on different supports; metallic grids and glass fibers. The materials are characterized by diverse physicochem. methods. The chem. pretreatment of the support is a crucial parameter for ...
