Scientists have reported the first experimental observation of ultrafast charge transfer in photo-excited MX2 materials. The recorded charge transfer time clocked in at under 50 femtoseconds, comparable to the fastest times recorded for organic photovoltaics.
For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. The effect could be used to build logical switches which are much faster than today's microelectronics.
Researchers have created dynamic nanoparticles that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents to light up tumors for MRI and PET scans or deliver chemo and other therapies to destroy tumors.
Researchers present the fabrication and characterization of large arrays of inkjet-printed superparamagnetic polymer composite (SPMPC) hemispherical microstructures. SPMPCs are appealing for applications in microsystems and nanorobotics due to the added functionality of polymers and the significant magnetic attributes of embedded nanostructures.
For his PhD thesis Pedro Jose Rivero, graduate in Chemistry and Biochemistry, carried out research into the synthesis of silver nanoparticles and their subsequent incorporation into ultra-thin coatings.
Scientists have managed to take a unique look at the membranes of human cells using a new technique. This technique that they have devised makes individual saccharified proteins and lipids visible at the molecular level.
The new MicroNano Research Facility (MNRF) will bring to Australia the world's first rapid 3D nanoscale printer and will support projects that span across the traditional disciplines of physics, chemistry, engineering, biology and medicine.
Scientists have demonstrated that they can detect extremely small changes in position and forces on very small drums of graphene. Graphene drums have great potential to be used as sensors in devices such as mobile phones.
Bringing two electrical insulators together to create an electrical superconductor: Anyone wishing to analyze such phenomena in nanostructures will soon come up against metrological limitations - unless a new method is used that physicists have developed.
Researchers have found one new gold molecule, a catalyst containing exactly 25 gold atoms, that is powerful as well as sophisticated. It catalyzes the conversion of a variety of molecules, including the transformation of poisonous carbon monoxide into harmless carbon dioxide, a reaction that may find application in devices near gas flues or wood-burning stoves.
