It all comes down to bridging a gap. Researchers are helping companies develop new materials and products —- self-consolidating concrete columns and prestressed concrete bridge girders -- that bridge a physical gap.
Graphene is easy to acquire, at least in small amounts. The first scientists to isolate the strong, two-dimensional carbon material simply pressed a piece of Scotch tape to a chunk of graphite and peeled it off.
One strategy for addressing the world’s energy crisis is to stop wasting so much energy when producing and using it, which can happen in coal-fired power plants or transportation. Nearly two-thirds of energy input is lost as waste heat.
L'Université Carl von Ossietzky d'Oldenbourg (Basse-Saxe) a récemment lancé un nouveau groupe de recherche, baptisé "Cascade Use" , et dont les travaux portent sur l'amélioration de l'usage des matières premières.
Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to mechanical engineers who also see applications for batteries, biosensors and optical electronics as outlets for this...
By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer.
In Nature Materials, a team led by Coleman (and funded by the UK-based firm Thomas Swan) describe how they took a high-power (400-watt) kitchen blender and added half a litre of water, 10–25 millilitres of detergent and 20–50 grams of graphite...
Les plasmons sont des analogues des phonons en mécanique quantique mais dans les gaz d'électrons libres à l'intérieur des métaux. Ils permettent de développer une branche de la nanophotonique appelée plasmonique.
Engineers have created new ceramic materials that could be used to store hydrogen safely and efficiently. The researchers have created for the first time compounds made from mixtures of calcium hexaboride, strontium and barium hexaboride.
Scientists have reported the first experimental observation of the quantum critical point in the extensively studied 'unconventional superconductor' TiSe2, finding that it does not reside as predicted within the superconducting dome of the phase...
