Conducting AFM measurements on self-assemblies of platinum nanoparticles including polyoxometalates show that the polarizability molecules is a key parameter to consider electron transport.

Three novel polyoxometalates (POMs) containing [Ni6(μ3-OH)3](9-) and [P2W15O56](12-) units were first made, showing the first hexa-nuclearity transition-metal substituted POMs (TMSPs) based on monomeric lacunary Dawson fragments, which further indicates that the hydrothermal technique can offer an effective way for making new TMSPs through lacunary POM fragments incorporated with high-nuclear T...

a new model is proposed in this research to calculate the longitudinal strengthof unidirectional e-glass reinforced polymer composites exposed to sulfuricacid environment, using a micromechanics model. in the proposed method,it is assumed that the residual strength of the degraded composites under acidic environment can be calculated by knowing the degraded strength properties of the constituen...

A strategy of sequential modification organic and inorganic components gave rise to a stepwise photophysical investigation the photochromic performances supramolecular assemblies polyoxometalates with normal or mixed dithienylethenes.

The mixed-valent cerium(III/IV) oxide clusters {Ce(10)} and {Ce(22)}, derived from condensation reactions of cerium carboxylate coordination polymers, exhibit molecular growth tendencies similar to those of 'classical' group V and VI polyoxometalates, but with increasing nuclearity approach the structure of the parental oxide, CeO(2).

The encapsulation of polyoxometalates within the large pores of the Zr(iv) biphenyldicarboxylate UiO-67 metal-organic framework has been achieved, for the first time, by direct solvothermal synthesis. The resulting POM@UiO-67 composite materials were fully characterized by XRPD, IR, MAS NMR, N2 porosimetry measurements and cyclic voltammetry.

the transport properties of liquids and gases through polymeric materialsplay a very important role in some areas of industrial applications. in thisstudy, natural rubber (nr)/caco3 composites were prepared by melt mixingmethod. by equilibrium swelling test, the transport process of toluene in the prepared natural rubber composites was investigated. the diffusion and transport of toluene throug...
