Layered materials draw attention in recent years in response to the world-wide drive to discover new functional materials. High-Tc superconducting oxide is one example. Internal interfaces in such layered materials differ significantly from those of cubic metals. They are often parallel to the layer of the neighboring crystals in sintered samples(layer plane boundary), while periodically ordered interfaces with the two neighboring crystals in mirror symmetry to each other are relatively rare. Consequently, the atomistic features of the interface differ significantly from those of cubic metals. In this paper grain boundaries in sintered high-Tc superconducting oxides, joined interfaces between engineering ceramics with metals, and polytype interfaces in vapor-deposited bicrystal are examined to collect atomic information of the interfaces in layered materials. The analysis proved that they are not neccessarily more complicated than that of simple grain boundaries in cubic metals. The interfaces are majorly layer plane type which is parallel to the compound layer. Secondly, chemical information is often available, which helps the interpretation of the interface atomic structure.

Epoxy resins have been presenting a lot of scientific and technical interests and organic modified epoxy resins have recently receiving a great deal of attention. For obtaining the composite materials with good mechanical proprieties, a large variety of organic modification agents were used. For this study gluten and gelatin had been used as modifying agents thinking that their dispersion inside the polymer could increase the polymer biocompatibility. Equal amounts of the proteins were milled together and the obtained compound was used to form 1 to 5% weight ratios organic agents modified epoxy materials. To highlight the effect of these proteins in epoxy matrix mechanical tests as three-point bending and compression were performed.

A computational procedure has been suggested enabling estimates of the flexibility of individual layered materials from their crystallographical structure. The data about flexibility of layers have been obtained by calculation for compounds of the type Q2Y3 (Q = SbIII, BiIII; Y = Se-II, Te-II; space group of symmetry R3m), MPS3 (M = MnII, FeII, CoII, NiII, CdII,C2/m), TX2 (T = NbIV, TaIV, MoV; X = S-II, Se-II; P63/mmc), FeOCl (Pmnm), Zr(HPO4)2 (P21/n) and ROPO4 (R = VV, NbV, Mo; P4/n). The flexibility of the layers of these compounds increases in the order: Q2Y3 << MPS3 < TX2 < FeOCl = Zr(HPO4)2 < ROPO4. The same trend is observed for the ability of these compounds to form intercalates. In most of the structures given a distinct anisotropy of flexibility has been found by the calculation.
