We investigate the behavior of localized spots in three spatial dimensions in a model two-variable system describing the Belousov-Zhabotinsky reaction in water-in-oil microemulsion. We find three types of instabilities: splitting of a single spot (i) into two spots, (ii) into a torus, and (iii) into an unstable shell that splits almost immediately to six or eight new spots.

Black titania prepared by metal-reduction methods is systematically studied and found the best controllable Mg-reduction method. Colored titania products from white, light blue, dark blue, to black were obtained with a crystalline/amorphous core-shell structure. The black titania shows a five times higher H2 production rate in photoelectrochemical (PEC) water splitting.

Goal. To establish the influence of quantitative biometric parameters black nut fruit on dormancy its seeds. Methods. The results research were processed according to generally accepted methods in agriculture, plant growing, statistics. Field — collect fruits, measuring weight determine parameters, spectrometric, mathematical-statistical carry out analysis variance and statistical processing as...

Research funded by this award focused on the synthesis of unique plasmonic nanoparticles, preparation of core-shell particles to enhance the generation of hydrogen via the photocatalytic splitting of water, and mechanistic studies of the charge transfer of such core-shell particles. A particular emphasis centered on the synthesis and study of hollow gold-silver nanoshells (GSNSs) having tunable...

Carrying a large, pure spin magnetic moment of 7 μB per atom in the half-filled 4f shell, divalent europium is an outstanding element for assembling novel magnetic devices in which a two-dimensional electron gas may be polarized due to exchange interaction with an underlying magnetically-active Eu layer. Here we show that the Si-Rh-Si surface trilayer of the antiferromagnet EuRh2Si2 bears a sur...

We study the interplay of crystal field splitting and Hund coupling in a two-orbital model which captures the essential physics of systems with two electrons or holes in the e(g) shell. We use single site dynamical mean field theory with a recently developed impurity solver, which is able to access strong couplings and low temperatures. The fillings of the orbitals and the location of phase bou...

A model of interface induction for interlayer growing is proposed for bandgap engineering insights into photocatalysis. In the interface of CdS/ZnS core/shell nanorods, a lamellar solid solution intermediate with uniform thickness and high crystallinity was formed under interface induction process. Merged the novel charge carrier transfer layer, the photocurrent of the core/shell/shell nanorod ...
