In this study, adhesion and spreading of human skin fibroblasts on gradient surfaces of dichlorodimethylsilane (DDS) coupled to glass was investigated. Gradient surfaces were prepared by the diffusion technique and characterized by the Wilhelmy plate technique and characterized by the Wilhelmy plate technique for thei…
Compression experiments in which plastically deformed austenite is allowed to transform to bainite have revealed that bainite, like martensite, is susceptible to mechanical stabilisation. The overall transformation kinetics becomes slower and the maximum attainable fraction of bainite decreases in deformed austenite.…
Structural instabilities and electronic properties of ${\mathrm{PrZrO}}_{3}$ are investigated using local-density calculations. Substantial hybridization is found in the electronic band structure, both between O 2p and Zr 4d states and between O 2p and Pb s and p states. A very strong \ensuremath{\Gamma} point phonon…

The effect of dopants on the characteristics of titania particles made by oxidation of TiCl 4 in a laminar diffusion flame reactor is presented. Introduction of dopant SiCl 4 inhibits the transformation of anatase to rutile, due to the formation of interstitian solid solution of SiO 2 and TiO 2 . Silica decreases the…

Abstract The acidification of aqueous solutions containing Na2MoO4·2H2O in the presence of a chiral lysine ligand (d- and l-form) gives octamolybdates coordinating two lysine ligands, Na2[Mo8O26(d-lysH2)2]·8H2O (Mo8-d) and Na2[Mo8O26(l-lysH2)2]·8H2O (Mo8-l) (where lysH2 is 2,6-diammoniohexanoato), respectively. These…

The tricarboxylic acid cycle enzyme fumarase catalyzes the interconversion of fumarate to L-malate. Escherichia coli contains three biochemically distinct fumarases. While the fumA and fumB genes encode heat-labile, iron-containing fumarases, the fumC gene product is a heat-stable fumarase which does not require iron…

Based on experimental findings, a mechanism of structural formation during the induction period of polymer crystallization is proposed. Recently we have found that, during the induction period of crystallization of poly(ethylene terephthalate) before crystal nuclei are produced, a correlation peak appears in small-ang…

${\mathrm{SrTiO}}_{3}$ belongs to the class of incipient ferroelectrics in which an electrically ordered state is suppressed by quantum fluctuations. To investigate the nature of these excitations, we have measured the linear and nonlinear susceptibilities of ${\mathrm{SrTiO}}_{3}$ as a function of temperature T and f…
A mathematical model of a tubular solid oxide fuel cell is presented. The complete electrochemical and thermal factors are accounted for in a rigorous manner. All required parameters are determined from independent sources; none are fit from performance data. To verify the accuracy of the model predictions, comparison…
