The cellulose derivative hydroxypropyl methylcellulose (HPMC) has recently been extensively studied and used in mechanical applications. However, the softness susceptibility to deformation of HPMC limited its further In this study, metal nanoparticles (nano-aluminum nano-copper) nano-metal oxide particles (nano-alumina nano-copper oxide) were as additives form a composite film with improved pro...

The application of nanomaterial in cancer treatment is promising and intriguing. Anti-tumor immunotherapy has the potential to significantly improve the prognosis of cancer treatment, though the efficacy of immunotherapy generally needs further improvement. One way to improve the efficacy is using immune adjuvants, but the adjuvants for anticancer immunotherapy have to be more potent than for p...

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...

in the present study, development of new asbestos-free brake pad using lingo-cellulosic fibers and nano aluminum oxide particles was investigated. variable factors were the type of lignocellulosic materials (jute, bagass and rice husk) and the size of aluminum particles (nano and micron). these newly formulated brake pads have been tested under the grey cast iron disc. friction coefficient and ...

Tapered nanopillar structures of different cross-sectional geometries including cone-, pencil-like, and stepwise are prepared from anodized aluminum oxide templates. The shape effect on the adhesion strength is investigated in experiments and simulation. Cone-shaped nanopillars are highly bendable under load and can recover after unloading, thus, warranting high adhesion strength, 34 N cm(-2) ....

Studying the properties of structures where at least one spatial dimension is on the nanometer scale is motivated by many factors from engineering (such as the semiconductor industry’s push towards higher density integrated circuits), chemistry (developing methods to produce particles of well controlled size and structure), biology (using DNA to control the self-assembly of small structures) an...

The paper presents novel structures of Nano gas sensor arrays by using ZnO and doped with aluminum . ZnO Nanomaterial are successfully prepared using sol-gel technique . These include, similar and dissimilar structures. All used sensors are composed of zinc oxide doped with aluminum at different concentrations for dissimilar structures, and with the same concentration for similar structures. Th...

In this study, a multi nanosensor was fabricated for the simultaneous detection of carbon dioxide, methane, ethanol, and ammonia gases, and its electrochemical response to various concentrations of these gases were investigated. In order to fabricate this multi nanosensor, in the first phase, the Graphene-Oxide/Polyaniline (GO/PANI) nanocomposite was synthesized. Chemical ...

This study demonstrates a mass production method using nanoporous Anodized Aluminum Oxide (AAO) templates as mould insert tools that are used to structure large area polymer surfaces by a micro injection moulding process. SEM and water contact angle measurements served to evaluate the effect of nanostructures on surface properties. Human umbilical vein endothelial cells were cultured on nano-st...

In this study, molybdenum-copper/alumina nano composite was synthesized with mechano-chemical method using high energy planetary ball milling. The molybdenum oxide, copper oxide and aluminum powder were used as starting materials and reaction appeared to occur through a rapid combustion reaction process. The evaluation of powder particles after different milling times was studied by X-ray diffr...
