For the first time, a team of scientists from the Georgia Institute of Technology and Columbia University (USA) has managed to demonstrate the piezoelectric properties of a material as flexible as graphene, generating electric current through mechanical deformations in molybdenum disulfide, which has resulted in the finest electrical generator ever achieved.
In the world of science to say that something will never happen is almost a good joke, thankfully. Now, a nanoparticle has defied the laws of thermodynamics, specifically the second, by being able to transfer heat to an even hotter gas. The results of the work have been published in the journal Nature Nanotechnology.
A team of engineers from the Massachusetts Institute of Technology (MIT) has managed to design living materials (biofilms or biofilms) that can incorporate non-living materials such as quantum dots or gold nanoparticles. All from bacterial cells. The work has been published in the journal Nature Materials.
A team of researchers from the Institute of Photonic Sciences (ICFO) in Barcelona has managed for the first time in history to capture and move a nano-object in 3D using only the force of light, thanks to nano-sized optical tweezers. The study has been published in the journal Nature Nanotechnology.
Researchers from the University of California and the University of Surrey in the United Kingdom have managed to discover a new method to grow stem cells without the need to use animal proteins or by culturing other human cells. The study has been published in the journal Applied Materials & Interfaces.
Researchers at the University of California are experimenting with a new drug that would eliminate alcohol from the body in just seconds. The pill, released in the journal Nature Nanotechnology, has already achieved optimal results in laboratory mice. The drug is based on the combination of two complementary enzymes in a small capsule in order to accelerate the elimination of alcohol from the body. According to Yungefu Lu, lead author of the research, these two enzymes chemically alter alcohol in the stomach and process it in much the same way as the liver does, but much faster.
Scientists at the University of Twente (Holland) have developed a technology that allows living cells to be trapped inside tiny microscopic pyramids in order to study them. The pyramids, created with three-dimensional fabrication techniques at the nanoscale, have open walls to allow cells to interact with each other, as the researchers describe in the journal 'Small'.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
