LiMnO2 is one of only a few ternary oxides which are known to form in the orthorhombic Pmmn structure. The layered α-NaFeO2 structure, favored for application as a Li-insertion electrode, is found in many other alkali transition metal oxides. We find that the the strong antiferromagnetic interactions between Mn+3 ions contribute to the stabilization of the orthorhombic structure. Using first-pr...

In the field of genetic research and the subsequent rise of biobanks an intensive discussion is taking place on national and international levels about property and personality rights to one’s own body and body parts. The authors attempt to develop on the basis of the current controversially discussed law a concept of property, which can solve the legal and bioethical problems of the multiple u...

Numerous examples of closed-cage nanostructures, such as nested fullerene-like nanoparticles and nanotubes, formed by the folding of materials with layered structure are known. These compounds include WS2, NiCl2, CdCl2, Cs2O, and recently V2O5. Layered materials, whose chemical bonds are highly ionic in character, possess relatively stiff layers, which cannot be evenly folded. Thus, stress-reli...

Consider a layer made of a m3m insulator crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For a Xor Y -cut of the substrate, a Love wave can propagate in the resulting structure and the corresponding dispersion equation is derived analytically. It turns out that a fully explicit treatment can also be conducted in the case of a ...

Learning processes using New Media tend to be extremely complex. It is not too surprising then that current research appears rather scattered and dominated by the more tangible issues such as content and learning platform design in a bottom-up approach. While initially this appears practical, we are convinced that advanced learning platforms need to be designed to optimally support the underlyi...

This study constructed a multi-layered semantic structure of adjective pairs that are used to express the tactile properties of materials. We analyzed the causalities between adjectives using the DEMATEL method, involving twenty-nine adjective pairs and forty-six materials, and thus constructed a multi-layered structure. The constructed structure contained psychophysical, affective, and prefere...
