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...
In this paper, the nano-CMOS hybrid Autonomous Error-Tolerant (AET) cellular network architecture, which integrates today’s mature CMOS technology with emerging nanotechnology, is proposed. Within the cellular network, each AET cell contains a nanocore, CMOS cell peripherals and their interface circuits. The overall network is homogenous. These imply strict constraints for intercellular connect...
Nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. Theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. The better mechanical properties can be obtained ...
Spider silk-inspired peptide multiblock hybrid copolymers composed of alternately aligned self-assembling oligopeptides and flexible polypropylene glycol were newly designed for functional nano/microfilm materials.
The tribological performances of the SiO₂/MoS₂ hybrids as lubricant additives were explored by a reciprocating ball-on-flat tribometer for AZ31 magnesium alloy/AISI 52100 bearing steel pairs. The results demonstrated that the introduction of SiO₂/MoS₂ hybrids into the base oil exhibited a significant reduction in the friction coefficient and wear volume as well as an increase in load bearing ca...
The viscosity of polydispersed graphene nanosheet (5 nm–1.5 lm) suspensions (GNS) and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced viscosity over the base fluids has been proposed for the polydispersed GNSs. Experimental data reveal that enhancement of viscosity for GNSs lies in between those of carbon nanotube suspen...
In this work, we have proposed a revolutionary neuromorphic computing methodology to implement All-Skyrmion Spiking Neural Network (AS-SNN). Such proposed methodology is based on our finding that skyrmion is a topological stable spin texture and its spatiotemporal motion along themagnetic nano-track intuitively interprets the pulse signal transmission between two interconnected neurons. In such...
We present the implementation of aligned carbon nanotubes (CNTs) as a method to enhance properties of traditional advanced composites. The hybrid composites are 3-dimensional architectures of aligned CNTs, and existing advanced fibers and polymeric resins creating nanoengineered composites. Our work to date has focused on interlaminar strength and toughness, and electrical and thermal conductiv...
Nanomaterials find increasing application in communications, renewable energies, electronics and sensing. Because of its unsurpassed speed and highly tuneable interaction with matter, using light to guide the self-assembly of nanomaterials can open up novel technological frontiers. However, large-scale light-induced assembly remains challenging. Here we demonstrate an efficient route to nano-as...
The present study examined the gas-phase photocatalytic degradation of toluene using ZnO-SnO2 nanocomposite supported on activated carbon in a photocatalytic reactor. Toluene was selected as a model pollutant from volatile organic compounds to determine the pathway of photocatalytic degradation and the factors influencing this degradation. The ZnO-SnO2 nanocomposite was synthesized through co-p...
