ORNL researchers find 'greener' way to assemble materials for solar applications
The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists at the Department of Energy's Oak Ridge National Laboratory have found a 'greener' way to control the assembly of photovoltaic polymers in water using a surfactant -- a detergent-like molecule -- as a template.

Graphene teams up with two-dimensional crystals for faster data communications
In the recent work published today in Nature Nanotechnology, the research group led by professor at ICFO Frank Koppens has shown that a two-dimensional crystal, combined with graphene, has the capability to detect optical pulses with a response faster than 10 picoseconds, while maintaining a high efficiency.

Observing the unobservable: Researchers measure electron orbitals of molecules in 3-D
Electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists from the University of Graz, Forschungszentrum Jülich, and the Physikalisch-Technische Bundesanstalt have now succeeded in experimentally recording these structures in all three dimensions. They achieved this by further developing a method they had already applied two years ago to make these orbitals visible in two dimensions. Their findings have now been published in the scientific journal Nature Communications.

Molecular nanoribbons as electronic highways
Physicists at Umeå University have, together with researchers at UC Berkeley, USA, developed a method to synthesise a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells. The results have been published in the scientific journal ACS Nano.

Electron tomography with 3,487 images in 3.5 seconds
Scientists from the Ernst Ruska-Centre used a transmission electron microscope to record almost 3,500 images in 3.5 seconds for the reconstruction of a 3-D electron tomogram. Previously, 10 to 60 minutes and a ten-fold greater electron dose were required to record such image sequences. The new capability is particularly suitable for examining cells, bacteria, viruses and dynamic processes, such as chemical reactions and electronic switching phenomena. The findings have been published in Scientific Reports.

Semiconductor nanoparticles show high luminescence in a polymer matrix
Toyohashi Tech researchers in cooperation with researchers at the National Institute of Technology, Kurume College have demonstrated the formation of composite nanoparticles of luminescent ZnO quantum dots and polymer by dispersion polymerization in supercritical CO2. Embedding quantum dots in polymeric matrices enhances their stability and prevents agglomeration. This research shows that the supercritical-fluid-assisted process provides an environmentally benign process for producing stabilized luminescent materials.

Phoenix effect: Resurrected proteins double their natural activity
Researchers from ITMO University and the Hebrew University in Jerusalem discovered a novel mechanism of protein resurrection, which not only restores the active function of the protein, but also increases its original activity by almost two times. The scientists termed the observed phenomenon the Phoenix effect, drawing from the cross-culture mythology which uses the Phoenix legend as a symbol for rebirth into even stronger self. The results of the study were published today in Scientific Reports.

Physicists map the strain, pixel by pixel, in wonder material graphene
In a study published in Nature, a team of scientists map the strain in graphene, a 2-D sheet of carbon that is strong, flexible and can expand without breaking. Though the material has found its way into several applications, ranging from tennis rackets to smartphone touch screens, several obstacles are holding up further commercialization of graphene. One of these is the presence of defects that impose strain on graphene's lattice structure and adversely affects its electronic and optical properties.

Researchers disguise drugs as platelets to target cancer
Researchers have for the first time developed a technique that coats anticancer drugs in membranes made from a patient's own platelets, allowing the drugs to last longer in the body and attack both primary cancer tumors and the circulating tumor cells that can cause a cancer to metastasize. The work was tested successfully in an animal model.

New processes in modern ReRAM memory cells decoded
Resistive memory cells or ReRAMs for short are deemed to be the new super information-storage solution of the future. At present, two basic concepts are being pursued, which, up to now, were associated with different types of active ions. But this is not quite correct, as Jülich researchers working together with their Korean, Japanese and American colleagues were surprised to discover. The effect enables switching characteristics to be modified as required.

Hopes of improved brain implants
Neurons thrive and grow in a new type of nanowire material developed by researchers in Nanophysics and Ophthalmology at Lund University in Sweden. In time, the results might improve both neural and retinal implants, and reduce the risk of them losing their effectiveness over time, which is currently a problem.
