The fundamental laws of thermodynamics do not apply to objects on the nanoscale to the extent they do in our macroscopic world. A team of researchers describe how heat can transfer from cold to hot objects in the nanoworld.
In the last 12 months more than 13,000 people have run simulations and 309,000 have made use of tutorials, lectures, or seminars at nanoHUB.org, a science and engineering gateway made up of community-contributed resources.
About the size of a stapler, this new handheld device developed in Switzerland is able to test a large number of proteins in our body all at once-a subtle combination of optical science and engineering.
Rice University researchers have developed a noninvasive technology that accurately detects low levels of malaria infection through the skin in seconds with a laser scanner. The "vapor nanobubble" technology requires no dyes or diagnostic chemicals, and there is no need to draw blood.
Scientists have made another advance when it comes to using liquid crystals as a medium to assembling structures. They've managed to grow liquid crystal "flowers" that can be used as lenses.
One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. Researchers have now found a way to improve this technique by using a material with unique properties: graphene.
The UK launch of the European Union's new €70 billion Euro programme for research and innovation, the Horizon 2020 programme, is imminent. Among the programme's key goals is to tackle societal challenges by helping to bridge the gap between research and commercial organisations.
James Tour has enhanced a polymer material to make it far more impermeable to pressurized gas and far lighter than the metal in tanks now used to contain the gas.
Using LEGO, the world’s first low cost Atomic Force Microscope (AFM) has been developed in Beijing by a group of PhD students from University College London (UCL), Tsinghua University and Peking University
UCLA engineers have created a 1/2-pound, portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment.
When scientists look for keys to unlock problems such as quantum teleportation or faster internet speeds, answers can sometimes be found in the natural world.
As a further development of well-known microscopic and mass spectroscopic methods, the 3D NanoChemiscope maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "s...
