(Nanowerk News) Inspired by the microstructure and thermal insulation function of the polar bear hair, scientists have used a freeze-spinning technique to continuously fabricate silk fibroin solution into a fiber with aligned porous microstructure. The textile woven with the biomimetic fibers has an excellent thermal insulation, active...

(Nanowerk News) Getting an injection at the doctor’s office is never a fun thing, but a new approach is on the horizon, using what are called microneedles, arrays of tiny needles that deliver medication through the skin without causing pain. But fabricating microneedles is costly, requiring cleanrooms and expensive equipment. Now a Tufts research...

(Nanowerk News) Uncomfortable, rigid, with low air permeability: textile materials capable of conducting electricity can be awkward for day-to-day use. However, researchers at the University of Bayreuth, Donghua University in Shanghai, and Nanjing Forestry University have now developed new nonwoven materials that are electrically conductive as well...

(Nanowerk Spotlight) Aerogels, sometimes called frozen smoke, are nanoscale foams: solid materials whose sponge-like structure is riddled by pores as small as nanometers across. They can be made from different materials, for instance silicon. Aerogels are among the lightest solid substances in the world yet flexible, extremely strong and water...

(Nanowerk News) Researchers at Queen Mary University of London have discovered that cells can ‘walk’ on liquids a bit like the way geckos stick to other surfaces. Cells are typically grown on solid materials, such as tissue culture plastic, degradable polymers and bioceramics. It is thought that the strong mechanical properties of these...

(Nanowerk News) Integrating nanoscale fibers such as carbon nanotubes (CNTs) into commercial applications, from coatings for aircraft wings to heat sinks for mobile computing, requires them to be produced in large scale and at low cost. Chemical vapor deposition (CVD) is a promising approach to manufacture CNTs in the needed scales, but it produces...

(Nanowerk News) A residential module fully constructed from reusable, recyclable, and compostable materials: This is the premise for the newest unit in NEST, the modular research and innovation building run by Empa and Eawag in Dübendorf. On 8 February 2018, the NEST “Urban Mining & Recycling” unit will open its doors and henceforth house two...

(Nanowerk News) A team of researchers at the Institute of Synthetic Polymer Materials of the Russian Academy of Sciences, MIPT, and elsewhere has found out how the regularity of polypropylene molecules and thermal treatment affect the mechanical properties of the end product. Their new insights make it possible to synthesize a material with...

(Nanowerk News) The construction of a polymer from a chain of boron atoms is currently more science fiction than science – this is the dream of Würzburg Chemistry Professor Holger Braunschweig, who has just received a 1.5 million Euro grant to make boron polymers a reality. Plastic bags from polyethylene, packaging from polystyrene, frying pans...

(Nanowerk News) The calculation is simple: the better a building is insulated, the less heat is lost in winter – and the less energy is needed to achieve a comfortable room temperature. No wonder, then, that the Swiss Federal Office of Energy (SFOE) regularly raises the requirements for building insulation. Traditionally, the insulating layers are...
