nanofluids are colloidal suspension of nanoparticles in a base fluid and have superior thermal properties in comparison to their base fluids. novel properties of nanofluids are yet to be explored to the highest potential. currently extensive investigation has been done on thermal conductivity of metallic and oxide nanofluids. composites offer the advantage of tailor made properties and fluids w...
The lubrication is a prime requirement of metal cutting industries to assure high quality performance. conventional technique coolant flow less economical and eco-friendly. Recently, nano fluids found better fluid in machining due potential thermal heat transfer properties. role micro-lubrication techniques process optimization are equally important for improving literature review presents the ...
A nano-sandwich construct was built by combining two-dimensional graphene nanosheets (GNSs) and one-dimensional carbon nanotubes (CNTs) to improve the mechanical properties of hydroxyapatite-polyetheretherketone (HAP-PEEK) scaffolds for bone tissue engineering. In this nano-sandwich construct, the long tubular CNTs penetrated the interlayers of graphene and prevented their aggregation, increasi...
روش های معمول برای تهیه بنزوتیازول ها شامل تراکم 2-آمینوتیوفنول با کربوکسیلیک اسید ها، آلدهید ها و هم¬چنین ارتواسترها می باشد. در این کار، کاتالیست nano- γ-al2o3/bf3-n به عنوان کاتالیست اسید جامد تهیه شده است. برای تایید ساختار nano- γ-al2o3 و nano- γ-al2o3/bf3-n طیف مادون قرمز و پراش پرتو xگرفته شده است. مشتقهای بنزوتیازول از طریق تراکم آلدهید ها با 2-آمینوتیوفنول با استفاده از nano- γ-al2o...
Drug delivered can have significant effect on its efficacy. Some drugs have an optimum concentration range with in which maximum benefit is derived and concentrations above (or) below the range can be toxic or produce no therapeutic effect. Various drug delivery and drug targeting systems are currently under development. The main goal for developing such delivery systems is to minimize drug deg...
Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology. In this work cupric oxide nano flakes were...

Abstract In this study, super-amphiphobic nano-silica nanoparticles (SA-NPs) were used to enhance the shale stabilization performance of water-based drilling fluids (WBDFs) by altering surface wettability, preventing capillary self-priming effect, and plugging nano-micro pores shale. The results transmission electron microscopy, particle size distribution, scanning microscopy characterization r...
