aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (al(no3)3.9h2o) and ammonium sulfate ((nh4)2so4). the resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. the crystallinity and phase of  the as-synthesized and calcined samples were characteri...

Introduction: Benzene is a volatile compound in petroleum products and a major concern is its carcinogenic effects. The purpose of this study was to survey benzene removal ability of multi-walled carbon nano tubes by surface modified with calcium hypochlorite and sodium hypochlorite from aqueous solution. Methods:The removal of benzene was evaluated by aqueous solution by hybrid multi-walled c...

Nano-scale vacuum channel transistors possess merits of higher cutoff frequency and greater gain power as compared with the conventional solid-state transistors. The improvement in cathode reliability is one of the major challenges to obtain high performance vacuum channel transistors. We report the experimental findings and the physical insight into the field induced crystalline-to-amorphous p...

Recent advances in nanoscale bioreplication processes present the potential for novel basic and applied research into organismal behavioral processes. Insect behavior potentially could be affected by physical features existing at the nanoscale level. We used nano-bioreplicated visual decoys of female emerald ash borer beetles (Agrilus planipennis) to evoke stereotypical mate-finding behavior, w...

Nano-hydroxyapatite (nano-HAp) materials show an analogous chemical composition to the biogenic mineral components of calcified tissues and depending on their topography they may mimic the specific arrangement of the crystals in bone. In this work, we have evaluated the potential of four synthesized nano-HAp superstructures for the in vitro conditions of bone-repair. Experiments are underway to...

have been used as the active channel in nano-BioFETs through bottom-up approaches. [ 8 ] Wafer scale nano-BioFETs have been successfully fabricated through complementary metal oxide semiconductor (CMOS) compatible top-down microfabrication process which facilitates the mass production of such devices. [ 9 ] In any case, nano-BioFETs share the same sensing principle by affi nity-based detection,...

Present work demonstrates a detail simulation results on enhanced generation of localized surface plasmon resonance (LSPR) field condition in a periodically varying height metal nanopillars. This simulation work has been carried out using COMSOL Multiphysics software. LSPR field condition study in metal nanostructure is important for different fields of applications which include chemical and b...

BACKGROUND Nano bamboo charcoal is being widely used as sustained release carrier for chemicals for its high specific surface area, sound biocompatibility, and nontoxicity; however, there have been no reports on nano bamboo charcoal as sustained release carrier for traditional Chinese medicine (TCM). OBJECTIVE To study the effect of nano bamboo charcoal in absorbing and sustained releasing Eu...

In this paper we report the effect of the incorporation of nano-dimensional clay platelets, laponite, on the J-aggregation of a thiacyanine dye N,N'-dioctadecyl thiacyanine perchlorate (NK) assembled into Langmuir-Blodgett (LB) monolayers. pi-A isotherms and atomic force microscopic studies confirm the successful incorporation of clay platelets into the Langmuir monolayer of NK. J-aggregates of...
