Using X-ray scattering over a large range of scattering vectors, it is shown how to measure both the pore volume fraction and pore specific surface of an assembly of porous grains forming a powder. Depending on the presence or not of solvent in the inner pores and in the intergranular media, the scattered signal per u…

Applying the dynamical coherent potential approximation to a simple model, we have systematically studied the carrier states in $A_{1-x}$Mn$_xB$-type diluted magnetic semiconductors (DMS's). The model calculation was performed for three typical cases of DMS's: The cases with strong and moderate exchange interactions i…

Silver nanoprisms (∼74-nm edge length) were etched with HAuCl 4 to generate gold−silver alloy framework structures. Interestingly, these triangular nanoframes possess no strong surface plasmon bands in the ultraviolet or visible regions of the optical spectrum. By adding a mild reducing agent, l -ascorbic acid, gold a…

X-Cell is a novel indexing algorithm that makes explicit use of systematic absences to search for possible indexing solutions from cells with low numbers of calculated reflections to cells with high numbers of reflections. Space groups with the same pattern of systematic absences are grouped together in powder extinct…

Recently great advances have been made in demonstrating the viability of using carbon nanotubes (CNTs) to detect the presence of chemical gases such as NO 2, NH 3, and O 2, and they have led to the design of a new breed of sensor devices. Based on intrinsic CNTs, the devices are capable of detecting small concentratio…

Photoinduced electron accumulation in ZnO nanoparticles results in the bleaching of the exciton band as well as quenching of green emission. In the absence of an electron scavenger, photogenerated electrons are stored near the conduction band edge and promote charge recombination via a nonradiative process. By exposin…

A new biomimetic strategy for modification of biomaterial surfaces with poly(ethylene glycol) (PEG) was developed. The strategy exploits the adhesive characteristics of 3,4-dihydroxyphenylalanine (DOPA), an important component of mussel adhesive proteins, to anchor PEG onto surfaces, rendering the surfaces resistant t…

A reflection intensity integration method is presented based upon ab initio calculation of three-dimensional ( x , y , ω) reflection boundaries from a few physical crystal and instrument parameters. It is especially useful in challenging circumstances, such as the case of a crystal that is far from spherical, anisotro…

Cobalt(II), nickel(II), copper(II) and zinc(II) phthalocyanines substituted by eight alkoxy chains in the peripheral (2,3,9,10,16,17,23,24) positions were prepared. The alkoxy chain lengths are octyloxy (C 8 H 17 O), dodecyloxy (C 12 H 25 O) and hexadecyloxy (C 16 H 33 O). Studies by polarized optical microscopy and h…

A diffusion-corrected simultaneous multilayer (DCSM) model was developed, taking into account up-step and down-step diffusion of adatoms and enabling rapid identification of different film growth modes. This DCSM model was applied to the initial growth of Cr on (100) ${\mathrm{S}\mathrm{r}\mathrm{T}\mathrm{i}\mathrm{O…

The equation of state for Langmuir monolayers proposed earlier (Fainerman, V. B.; Vollhardt, D. J. Phys. Chem. B 1999, 103, 145.) is generalized for the case that one, two or more phase transitions in the monolayer take place, provided that the two-dimensional compressibility undergoes a jump at the phase transition,…

Six novel series of mononuclear ortho-palladated and ortho-platinated metallomesogens have been obtained by combination of rod-like heteroaromatic liquid crystals with bent or half-disc-shaped 1,3-diketonate units. The synthesis of these molecules was achieved by ortho-metallation of rod-like 2-phenylpyrimidines and 2…
