Many commercially important alloys such as Fe-C, Fe-Ni, Cu-Zn, Cu-Sn and Ti-Al exhibit peritectic transitions on solidification. In the two-solid phase region of peritectic metallic systems, a wide spectrum of microstructures has been revealed during direc ...
PLLA crystallization rates increase with nHA content owing to increased nucleation, which compensates a decrease in spherulite growth rate, G, at 100 to 130 °C, and to suppression of the twin peak in G(T) seen in pure PLLA, linked to a transition from the ...
The microstructural evolution of an Al-01 wt% Cu alloy was investigated during solidification at constant cooling rate by in situ synchrotron X-ray microtomography with a resolution of 2.8 mu m. Solidification of this alloy leads to a coarse dendritic micr ...
A surfactant-assisted nonaq. strategy, relying on high-temp. aminolysis of titanium carboxylate complexes, has been developed to access anisotropically shaped TiO2 nanocrystals selectively trapped in the metastable brookite phase. Judicious temporal manipu ...
The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...
The present paper describes what happens at the surface of a crystal as its temperature steadily increases from zero Kelvin close to the bulk melting temperature. We treat thermal motion, such as the diffusion of individual adatoms establishing mass transp ...
This article, the fourth in the series, presents kinetic and photochemical data sheets evaluated by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry. It covers the gas phase and photochemical reactions of organic halogen spec ...
The effect of nitrogen substoichiometry on the isostructural phase stabilities of the cubic Ti1-xAlxN1-y system has been investigated using first-principles calculations. The preferred isostructural decomposition pattern in these metastable solid solutions ...
This work describes the dilute solution and solid-state structure of polyelectrolyte complexes generated from hyperbranched polylysine (HBPL) and various anionic, sodium alkyl sulfate surfactants. In dilute solution, the radius of gyration (Rg) of the HBPL ...
Powder synchrotron X-ray diffraction studies confirm that 7-oxabicyclo[2.2.1]heptane, (oxanorbornane), forms three solid phases on cooling and four on warming, as previously indicated by spectroscopic and DSC meas urements. The two highest temperature phas ...
