A team of researchers from Siberian Federal University (SFU) obtained thin copper/gold and iron/palladium films and studied the reactions that take place in them upon heating. Knowing these processes, scientists will be able to improve the properties of materials currently used in microelectronics. The article of the scientists was published in the Journal of Solid State Chemistry.
A research team from ITMO University and the Australian National University has discovered that different metasurfaces exhibit the same behavior provided a symmetry breaking is introduced to their unit cells 'meta-atoms'. Asymmetry of meta-atoms results in high-quality (high Q) resonances in the transmittance spectra of metasurfaces. It opens the way to control an optical response, which is highly desirable for practical applications. The results of this research were published in Physical Review Letters.
In a paper published Oct. 8 in the journal Nano Letters, a team from the University of Washington and the National Tsing Hua University in Taiwan announced that it has constructed functional metalenses that are one-tenth to one-half the thickness of the wavelengths of light that they focus. Their metalenses, which were constructed out of layered 2D materials, were as thin as 190 nanometers -- less than 1/100,000ths of an inch thick.
Research team at TU Graz discovers atomic-level processes which can provide new approaches to improving material properties.
A team of researchers in France and at MIT has taken the first three-dimensional images of kerogen's internal structure, with a level of detail more than 50 times greater than has been previously achieved. The images should allow more accurate predictions of how much oil or gas can be recovered from any given formation.
Indiana University scientists paired drug-delivering nanoparticles like dance partners to reveal that molecules attach to targets on cells differently based upon their position in time. The discovery could improve methods for screening drugs for therapeutic effectiveness.
Scientists from the Center for Functional Nanomaterials (CFN)--a US Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory--have dramatically improved the response of graphene to light through self-assembling wire-like nanostructures that conduct electricity.
Machine learning is increasing the pace of development of customised carbon surfaces with a wide variety of applications
A new study by researchers from the National University of Singapore has uncovered a major problem - a lack of graphene production standards has led to many cases of poor quality products from suppliers. Such practices can impede the progress of research that depend fundamentally on the use of high-quality graphene
Neuronal development is often regulated by the graded distribution of guidance molecules, but many details about the process is largely unexplored. A research team from City University of Hong Kong (CityU) has tackled this problem in a precise and systematic way by developing a novel device, and has published their findings in the latest issue of Nature Communications.
