Ian Lindsay University of Bristol School of Physics Bristol, United Kingdom As a near-field expert I was quickly convinced that neaSNOM is the only optical AFM microscope completely satisfying the needs of demanding near-field experiments. Qijie Wang Nanyang Technological University Centre for Disruptive Photonic Technologies (CDPT) Singapore Developed by the s-SNOM experts, the neaSNOM microsocope is the ideal tool for our demanding applications

Posted: Jul 01, 2015 Read more Trapping individual metal nanoparticles in air While there is a great deal of knowledge on optical manipulation of metallic nanoparticles in liquids, aerosol trapping of metallic nanoparticles is essentially unexplored. One of the greatest challenges in commercializing graphene is how to produce high quality material, on an industrial scale, at low cost, and in a reproducible manner
Interpenetrating Polymer Networks as Innovative Drug Delivery Systems
Also, the modification and sterilization can be achieved in a single step and hence it is a cost-effective process to modify biopolymers having their end use specifically in biomedical application.5.3. IPNs have shown superior performances over the conventional individual polymers and, consequently, the ranges of applications have grown rapidly for such class of materials
NASA's Connell says that the volatiles can be dealt with by designing the cure cycle with specific ramp-ups and holds at different temperatures, to ensure the volatiles are driven out of the part to eliminate voids. While these resins, designed for primary structural applications in airframes and jet engines, produce tough composites, they do cost more than PMR-type materials

The kinetic parameters extracted from our single-molecule cleavage trajectories agree well with values obtained in bulk through other methods and confirm well known features of the cleavage process, such as DNA bending before cleavage. This strong enhancement arises from a controlled optical antenna effect in patterned core-shell nanostructures that consist of absorbing semiconductors and nonabsorbing dielectric materials
NASA Funding Research on Self-Repairing Composite Materials at Parabolic Arc
Potential Non-NASA Commercial Applications Non-NASA applications for the self-healing composites include long-term protective storage liners for food or other sensitive materials, self-sealing tires, anti-ballistic fuel tanks and life critical personnel protective equipment (PPE). Aurora and UMass Lowell will automate the resistive heating process by relying on changes in the flow of heat through the material as measured by sending electrical current through the structure and monitoring using infrared thermography
The interfacial interactions between CNCs and PAA could be further improved by heat-induced esterification between the CNC surface hydroxyls and PAA carboxyl groups, which produce covalent crosslinks at the PAA-CNC interfaces, render the nanocomposite fibrous mats insoluble in water, and make mats to be more thermally stable and far more superior tensile properties. Alignment of electrospun nanocomposite fibers reinforced with CNCs has been achieved by many techniques, including by running the fibers over a hollow spool with high rotation (Olsson et al., 2010), an aluminium frame with openings (Changsarn et al., 2011), a rotating mandrel covered with aluminium foil (Dong et al., 2012)
Braiding is suited to the manufacture of narrow width flat or tubular fabric and is not as capable as weaving in the production of large volumes of wide fabrics. In addition, the ability to recycle FRP composites is limited and, unlike steel and timber, structural components cannot be reused to perform a similar function in another structure

They include not only the minerals and organic building blocks of rubber, but also various plasticizers and accelerators used during the vulcanizing process. Int 918 - By Council Member Stewart - A Local Law to amend the administrative code of the city of New York, in relation to the surface areas of playgrounds and playing fields
Tumor cells will therefore continue dividing because they do so without regard to nutrient supply but also many tumor cells will die because the amount of nutrients is not enough. The ultimate goal of nanobiosensors is to identify disease at the earliest stage possible, ideally at the level of a single cell or multiple cells of cancer stages
According to The National Cancer Institute, Nanoparticulate technology can prove to be very useful in cancer therapy allowing for effective and targeted drug delivery by overcoming the many biological, biophysical and biomedical barriers that the body stages against a standard intervention such as the administration of drugs or contrast agents. Such an approach is particularly important in tumor therapy as the compounds are very toxic, and if they act on cells other than tumor cells, severe side effects are encountered

Electron microscopy reaches new heights Feb 26, 2015 (with audio) Researchers gathered at the inauguration of the SuperSTEM 3 electron microscope in Daresbury, UK, told nanotechweb.org about their outlook for the equipment and its high-resolution spectroscopic and spatial capabilities
Recently, their use as polymer fillers has allowed to increasingly extending their application range to innovative areas such as medical and biological fields as well as in sensors, filtration membranes, energy storage and novel catalysis routes
They could also be used to make lighter, more fuel-efficient aircraft and car parts, as well as stronger wind turbines, medical implants, and sports equipment. Researchers at Princeton University, who are coauthors of the paper, developed a way to isolate such graphene sheets from graphite oxide by expanding the material rapidly at high temperatures
However, inherent shortcomings of natural polymer-based packaging materials, such as low mechanical properties and low water resistance, are causing a major limitation for their industrial use
