Scientists from the London Centre for Nanotechnology at UCL have shown that animal cells behave according to the theory of poroelasticity when mechanically stimulated in a way similar to that experienced in organs within the body. The results indicate that the rate of cell deformation in response to mechanical stress is limited by how quickly water can redistribute within the cell interior.
Physicists have modified silicon carbide crystals in a way that these exhibit new and surprising properties. This makes them interesting with regard to the design of high-performance computers or data transmission.
The mathematician Naiara Arrizabalaga has studied in her PhD thesis of the UPV/EHU-University of the Basque Country the mathematical framework of one of the most famous and complex equations in physics:the Dirac equation.
Researchers succeeded in developing an on-demand-type device which possesses a diverse range of functions, including those of a diode, switch, capacitor, brain-type memory device, in a single device, and realizes the new concept of enabling switching of those functions in response to the user's needs.
Technologically valuable ultrastable glasses can be produced in days or hours with properties corresponding to those that have been aged for thousands of years, computational and laboratory studies have confirmed.
Diamond has excellent properties for high-power electronic devices. However, mechanical polishing leaves rough diamond surfaces, which diminishes the device performance. Now, researchers have identified the conditions for growing flat diamond films suitable for high-performance devices.
Researchers have created an atomic gas in the laboratory that nonetheless has negative Kelvin values. These negative absolute temperatures have several apparently absurd consequences: although the atoms in the gas attract each other and give rise to a negative pressure, the gas does not collapse - a behaviour that is also postulated for dark energy in cosmology.
