Interaction of cellular membranes with biointerfaces is vital importance for a number medical devices and implants. Adhesiveness these surfaces cells often regulated by depositing layer bovine serum albumin (BSA) or other protein coatings. However, anomalously large separations between phospholipid the in various conditions buffers have been observed, which could not be understood using availab...

Given a tropical line $L$ and smooth surface $X$, we look at the position of on $X$. We introduce its primal dual motifs which are respectively decorated graph subcomplex triangulation They encode combinatorial classify all possible lines general surfaces. This classification allows us to give an upper bound for number with given subdivision. focus in particular surfaces degree three. As concre...

Stable hydrophobic nanocomposites of magnetic nanoparticles and clay are prepared by the self-assembly of magnetite (Fe3O4) nanoparticles on surfaces of exfoliated clay platelets. Due to the attractive interaction between hydrophobic groups, oleic acid coated nanoparticles are strongly attached to the surface of cetyl trimethylammonium cation coated clay platelets in organic media. Crystal stru...

Controlling the self-assembly of nanoparticles in higher-order structures and guiding their deposition in defi ned arrays on surfaces are key challenges in nanoscience and important e.g. for applications in diagnosis and sensing. [ 1 , 2 ] To make ever more complex nanosystems, it is desirable to control (or “trigger”) nanoparticle assembly upon application of a specifi c stimulus. Mirkin et al...

density functional theory ,(dft) calculations have been performed to investigate the properties ofcarbon decorated (c-decorated) models of boron nitride (bn) nanocones. to this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the c-decorated models. theresults indicated that dipole moments and energy gaps could reveal the effects of c-decorations onthe pro...

Given a tropical line L on a tropical surface X, we define its combinatorial position on X to be a certain decorated graph, showing the relative positions of vertices of X on L, and how the vertices of L are positioned on X. We classify all possible combinatorial positions of a tropical line on general smooth tropical surfaces of any degree. This classification allows one to give an upper bound...

Many bacterial species use gliding motility in natural habitats because external flagella function poorly on hard surfaces. However, the mechanism(s) of gliding remain elusive because surface motility structures are not apparent. Here, we characterized the dynamics of the Myxococcus xanthus gliding motor protein AglR, a homolog of the Escherichia coli flagella stator protein MotA. We observed t...
