Scientists have succeeded in visualising this phenomenon using neutron scattering. • Email to a friend • Researchers are developing a new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object. • Email to a friend • Researchers have succeeded in creating thermoelectric coolers that are only 100 nanometers thick and have developed an innovative new technique for measuring their cooling performance. • Email to a friend • Researchers showed that a special material made of lanthanum, strontium, iron and oxygen can be switched back and forth between two different states: In one state the material is catalytically extremely active, in the other less so. The reason for this is the behavior of iron nanoparticles on the surface. • Email to a friend • Energy harvesting technology with automatic resonance tuning mechanism. Possible application for an stand-alone power source for IoT or small electronics. • Email to a friend • Cancer cells are killed in lab experiments and tumour growth reduced in mice, using a new approach that turns a nanoparticle into a 'Trojan horse' that causes cancer cells to self-destruct. • Email to a friend • Researchers have demonstrated the creation of a living micromotor with multifunctional capability. The distinctive feature of this device is that it doesn't require synthetic materials and therefore avoid the problems of energy consumption and waste production generated during material synthesis. Using microalgal Chlamydomonas reinhardtii cells as the sole material, the scientists made living and multifunctional micromotors controlled by optical force. This system might be particularly useful for indirect manipulation and controllable disruption of biological targets. • Email to a friend • Physicists have managed to achieve ultrastrong coupling between light and matter at room temperature. The discovery is of importance for fundamental research and might pave the way for advances within, for example, light sources, nanomachinery, and quantum technology. • Email to a friend • |
