نانوکامپوزیتهای پلی اتیلن (PE) حاوی ذرات نانوکریستال سلولز (CNC) از طریق مخلوط و ذوب شدن در یک اکسترودر دو مارپیچ تهیه شدهاند. در این تحقیق کاربردهای نانوکامپوزیتهای PE/CNC برای بستهبندی مواد غذایی با استفاده از تحلیلهای حرارتی و مکانیکی مورد بررسی قرار گرفتند. افزودن نانوذرات CNC تاثیری بر دمای ذوب و دمای کریستالیزاسیون نانوکامپوزیت نداشت، اما تاثیر زیادی بر درصد بلوری بودن پلی اتیلن نشان...
Single-walled carbon nanotubes have been demonstrated as effective nanoscale containers for a redox active organometallic complex Cp(Me)Mn(CO)3, acting simultaneously as nano-electrode and nano-reactor. Extreme spatial confinement of the redox reaction within the nanotubes changes its pathway compared to bulk solution due to stabilisation of a reactive intermediate.
Aqueous based controlled decoration of platinum nanoparticles on plasma treated carbon nano-onions (CNOs) occurs within the shear flow generated by a vortex fluidic device (VFD), using ascorbic acid as the reducing agent, with the electrocatalytic potential of the resulting Pt-NPs@CNOs nano-composites demonstrated.
We report on the evolution of a hollow sphere secondary structure of spherical nanoparticles by a solubilization-reprecipitation mechanism based on the difference of solubility products (K(sp)) of two different precipitates. Carbon-coated nanoparticles of olivine structure LiFePO(4) served as the primary nano-blocks to build the secondary nano-architecture.
Nano Letters is published by the American Chemical Society. 1155 Sixteenth Street N.W., Washington, DC 20036 Letter Rapid and Reproducible Fabrication of Carbon Nanotube AFM Probes by Dielectrophoresis Jie Tang, Guang Yang, Qi Zhang, Ahmet Parhat, Ben Maynor, Jie Liu, Lu-Chang Qin, and Otto Zhou Nano Lett., 2005, 5 (1), 11-14 • DOI: 10.1021/nl048803y Downloaded from http://pubs.acs.org on Janua...
Flat plate solar collectors can easily be termed as the most vastly studied alternative energy transforming and generating technology of twenty-first century. As world is racing towards fourth industrial revolution (Industry 4.0), more being consumed for mega projects to materialized. Electronic devices are not only confined conventional intermittent costlier electric energy, but also fuel. Sol...
A promising electrochemical sensor was fabricated by the self-assembling of Pt nanoparticles (nano-Pts) on a chitosan (CS) modified glassy carbon electrode (GCE). A field-emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM) and electrochemical techniques were used for characterization of these composites. It has been found that nano-Pts are inserted into the CS...
We report on the nano-electron beam assisted fabrication of atomically sharp iron-based tips and on the creation of a nano-soldering iron for nano-interconnects using Fe-filled multiwalled carbon nanotubes (MWCNTs). High energy electron beam machining has been proven a powerful tool to modify desired nanostructures for technological applications (1-4) and to form molecular junctions and interco...
The influences of nano-ZrO2 (NZ), nano-TiO2 (NT), nano-Fe2O3 (NF) and nano-Al2O3 (NA) additions on properties of the fresh and hardened cement paste in comparison with the fine cement paste were experimentally studied. Mini slump and flow cone tests were conducted on fresh cement pastes. Moreover the compressive and tensile strength of hardened cement paste were measured. SEM micrographs and XR...
the present study used a constant level of citric acid and polyvinyl alcohol and different amounts of nanocrystalline cellulose (cnc) and tio2 nanoparticles to improve the properties of starch film. the effect of different amounts of glycerol was also examined. the results of differential scanning colorimetry demonstrated that the addition of cnc increased the melting and glass transition tempe...
