Paper is known for its ability to absorb liquids, making it ideal for products such as paper towels. But by modifying the underlying network of cellulose fibers, etching off surface 'fluff' and applying a thin chemical coating, researchers have created a new type of paper that repels a wide variety of liquids - including water and oil.
Chemical engineering researchers at the University of Massachusetts Amherst report this week that they've discovered a new chemical process to make p-xylene, an important ingredient of common plastics, at 90 percent yield from lignocellulosic biomass, the highest yield achieved to date.
University of Madeira and Centro de Quimica da Madeira, Madeira Island, Portugal, invite applicants with a Bachelor or a Master degree in Chemistry, Biochemistry, Biology, Life Sciences, Materials, Physics or related sciences/engineering courses to apply to the 2nd Edition of the Master Programme in Nanochemistry and Nanomaterials.
What may be the ultimate heat sink is only possible because of yet another astounding capability of graphene. The one-atom-thick form of carbon can act as a go-between that allows vertically aligned carbon nanotubes to grow on nearly anything, including diamonds.
Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue. An enzyme produced by a specific type of tumor can trigger the transformation of the spheres into netlike structures that accumulate at the site of a cancer.
Cornell's National Science Foundation-supported nanotechnology experimentation and fabrication facility, has formed a partnership with the Smart System Technology and Commercialization Center in Canandaigua, N.Y., part of SUNY's College of Nanoscale Science and Engineering, to streamline the design process and help companies plan for mass manufacturing.
There were high hopes of using carbon nanotubes, particularly for ultra-fast water transport to desalinate seawater. However, a simulation now reveals that these ultra-fast transport rates might have not been properly grounded after all. Researchers who work with experiments and computer models have been at odds over the capabilities and governing physics of the material ever since.
Scientists have succeeded in building a microscope that allows magnifying the wave function of excited electronic states of the hydrogen atom by a factor of more than twenty-thousand, leading to a situation where the nodal structure of these electronic states can be visualized on a two-dimensional detector.
A light wave oscillates perpendicular to its propagation direction - that is what students learn in school. However, scientists of the Vienna University of Technology now perform atom-physics experiments with light oscillating in the longitudinal direction.
