Four kinds of cobalt-polyoxomolybdenum clusters were synthesized by a combination of polyoxomolybdates and a Co-tacn (tacn = 1,4,7-triazacyclononane) complex. The heterometallic polynuclear clusters were obtained by the reaction of Na2MoO4 and [Co(tacn)(H2O)3](CF3SO3)3∙H2O in aqueous solution. ...

Here we show a conceptual approach to realize the scanning probe based induced-assembly of fullerene (C60) molecules on top of a buffer organic adlayer at room temperature in solution environment. The realization of spatially-defined C60 assembly is attributed to modulation of substrate-molecular ...

A highly dense polymer brush was previously fabricated by the spontaneous segregation of amphiphilic diblock copolymers in an elastomer matrix into water and a hydrophobic polymer interface and named a ‘dynamic polymer brush’. We fabricated a lower critical solution temperature (LCST)-type ...

A main-chain nematic polymer melt/solution exhibits macroscopic orientational order of main polymer chains, i.e., a preferred (nematic) direction. It has long been known that in such polymeric liquid crystals spatial density/concentration variations and distortions of the nematic direction are ...

We revisit the charge-regulation mechanism of macro-ions and apply it to mobile macro-ions in a bathing salt solution. In particular, we examine the effects of correlation between various adsorption/desorption sites and analyze the collective behavior in terms of the solution effective screening ...

Crystalline solid solutions are a long known class of materials that enables the fine tuning of a material structure and properties. Some of them like metal alloys have been employed in everyday life for thousands of years. As result, these phases represent an important part of materials science. ...
