The increasing knowledge in nanoscience and materials technology promoted the development of advanced with enhanced unusual properties suitable for sustainable applications ranging from energy to environmental purposes. Here are presented some results our current investigations on composite semiconducting materials. investigated composites have been prepared different nitrogen precursors thin f...

Nanosheets have attracted much interest because of their characteristic properties originating from anisotropic and flexible structures. Inorganic nanosheets are synthesized from precursor layered compounds through exfoliation in a liquid phase. In contrast, a versatile exfoliation approach has not been fully studied for organic layered compounds. Here we report two exfoliation approaches for o...

Previously, I have proposed a model for post-attachment chromosome motions based on electrostatics and assumptions regarding net charge on kinetochores and the pericentriolar material of centrosomes. The present work shows that given the electric dipole nature of tubulin, layered water associated with electric charge, and the dynamic instability of microtubules, it is possible to account for th...

When search trees are made relaxed, balance constraints are weakened such that updates can be made without immediate rebalancing. This can lead to a speed-up in some circumstances. However, the weakened balance constraints also make it more challenging to prove complexity results for relaxed structures. In our opinion, one of the simplest and most intuitive presentations of balanced search tree...

Old and novel layered structures are attracting increasing attention for their physical, electronic, and frictional properties. SiS2, isoelectronic to SiO2, CO2 and CS2, is a material whose phases known experimentally up to 6 GPa exhibit 1D chain-like, 2D layered and 3D tetrahedral structures. We present highly predictive ab initio calculations combined with evolutionary structure search and mo...
