Nano-graphene/polymer composites can function as pressure induced electro-switches, at concentrations around their conductivity percolation threshold. Close to the critical point, dependence of electron tunneling through polymer barrier separating nano-graphene's results from competition among shortening length and increase polymer's polarizability. Such switching behavior was recently observed...

Fe and Co nano-whiskers platelets were synthesized via physical vapor deposition without any template catalyst. Transmission electron microscopic analyses revealed that the whiskers all single crystal with whisker axis along [1 0 0] crystallographic direction. Both FCC HCP structures found in stacking faults micro-twins. Off-axis Electron holography results showed magnetic domain structures. Vo...

BACKGROUND Polymers are attractive materials for both biomedical engineering and cardiovascular applications. Although nano-topography has been found to influence cell behaviour, no established method exists to understand and evaluate the effects of nano-topography on polymer-blood interaction. RESULTS We optimized a micro-fluidic set-up to study the interaction of whole blood with nano-struc...

Technological development in latent heat storage (LHS) systems is essential for energy security and management both renewable non-renewable sources. In this article, numerical analyses on a shell-and-tube-based LHS system with coupled thermal enhancement through extended fins nano-additives are conducted to propose optimal combinations guaranteed higher discharging rate, enthalpy capacity distr...

In the present study, the effect of various weight fractions of graphene nanoplatelet (GPL) on flexural fatigue behavior of epoxy polymer has been investigated at room temperature and generally the temperature was monitored on the surface of specimen during each test. The flexural stiffness of grapheme nano-platelet/epoxy nanocomposites at 0.1, 0.25 and 0.5 wt. % as a main effective parameter o...

In order to provide ultraviolet barrier, antifungal and antibacterial properties, nano-zinc oxide (ZnO) was added lamellar zirconium phosphate (ZrP). The synthesized via reaction of oxychloride octahydrate phosphoric acid following its chemical modification with Jeffamine nano-ZnO. Diffractometric, morphological, thermal, structural relaxometric evaluations were conducted. Fourier transform inf...

Mineral dust supplied to remote ocean regions stimulates phytoplankton growth through delivery of micronutrients, notably iron (Fe). Although attention is usually paid to Fe (hydr)oxides as major sources of available Fe, Fe-bearing clay minerals are typically the dominant phase in mineral dust. The mineralogy and chemistry of clay minerals in dust particles, however, are largely unknown. We con...
