The synthesis of nanosized phosphors by using the non-thermal plasma-driven method is presented. The method allows to control the average grain size of nanocrystals. The synthesis of Eu3+-doped Y2O3 nanocrystalline phosphors at water solution of nitrates is described. The average sizes of nanocrystals were controlled by sintering temperature. Their structure, morphology, and luminescent propert...

A hollow Fe2O3-TiO2-PtOx photocatalyst for visible light H2 generation was prepared from nanosized MIL-88B consisting of coordinatively unsaturated metal centers as a hard template. This photocatalyst is composed of hybrid metal oxide-TiO2 with controllable wall thickness and two different cocatalysts that are separately located on two surface sides.

We demonstrate optical trapping and manipulation of aerosols with an optical bottle beam generated by the moiré techniques. We observe stable trapping and back-and-forth transportation of a variety of absorbing carbon particles suspended in air, ranging from clusters of nanosized buckminsterfullerene C₆₀ to micrometer-sized carbon powders.

Weakly ferromagnetic cobalt nanoparticles can assemble spontaneously into nanosized "bracelets" when dispersed in organic solvents containing resorcinarenes as surfactants. Bracelet self-assembly occurs in solution and is directed by magnetic dipolar interactions, whereas nanoparticle rings with larger diameters are produced by evaporation-driven flow on wetted surfaces.

With the help of a two-dimensional model we study rolling lubrication by circular (“2D fullerenes”) molecules for a wide range of parameters. The conditions under which microscopic rolling friction may be effective are identified, and related to the relative ingraining between substrate and molecule, the latter behaving as a nanosized cogwheel.

Using Molecular Mechanics and Molecular Dynamics methods, we investigated at the atomistic level the topography effects both on physisorption on different crystalline planes of TiO2 anatase and on the competitive adsorption when three different crystallographic faces were simultaneously present in an idealized nanosized crystal interacting with a simple heteroaromatic molecule experimentally us...

This research provides a feasible strategy for the development and application of novel nanosized photocatalyst an innovative approach treatment freshwater aquaculture wastewater.

In a great number of technologically and biologically relevant cases, transport of micro- or nanosized objects is governed by both omnipresent thermal fluctuations and confining walls or constrictions limiting the available phase space. The present Topical Issue covers the most recent applications and theoretical findings devoted to studies of Brownian motion under confinement of channel-like g...

The recent developments and trends in combustion science towards the synthesis of nanomaterials are discussed.

Special attention is paid to various applications of combustion synthesized nanosized products. 2008 Elsevier Ltd. All rights reserved.

We herein present a top-down methodology to prepare nanosized zeolites with tunable size by combining post-synthesis milling and fast recrystallization of several minutes (10 min for SSZ-13 and 5 min for AlPO4-5). A continuous-flow recrystallization process is demonstrated to further enhance the overall product efficiency.
