By developing heat-, corrosion- and radiation-resistant electronics, researchers at the Stanford Extreme Environment Microsystems Laboratory hope to move research into extreme places in the universe—including here on Earth. And it all starts with tiny, nanoscale slices of material.
Researchers at North Carolina State University have developed a technique for converting positively charged reduced graphene oxide into negatively charged reduced graphene oxide, creating a layered material that can be used to develop transistors for use in electronic devices.
Solar cells and photodetectors could soon be made from new types of materials based on semiconductor quantum dots, thanks to new insights based on ultrafast measurements capturing real-time photoconversion processes.
With graphene, Rutgers researchers have discovered a powerful way to cool tiny chips. Using graphene combined with a boron nitride crystal substrate, the researchers demonstrated a more powerful and efficient cooling mechanism.
Using sunlight to drive chemical reactions, such as artificial photosynthesis, could soon become much more efficient thanks to metal nanoparticles. Researchers at Imperial College London have investigated an artificial photocatalyst material using nanoparticles and found out how to make it more efficient.
A group of Aalto University researchers has developed a manufacturing method for electrocatalysts that only uses one hundredth of the amount of platinum generally used in commercial products. The method is based on the special characteristics of carbon nanotubes.
Metal sulfide nanoparticle catalysts developed by Singapore’s Agency for Science, Technology and Research researchers can help split water to produce hydrogen, a clean-burning fuel that provides a convenient way to store renewable energy.
Teams at TU Wien have made targeted alterations to the surface of ceramic fuel cells on an atomic scale and took measurements at the same time. As a result, it is now possible to explain important phenomena for the first time, including why strontium atoms are problematic and the fact that cobalt can be useful in a fuel cell.
What if less fortunate countries and regions could use air instead of water as a way of storing energy? Under the auspices of the European Union, scientists from all over Europe are attempting to turn this concept into a viable prospect.
Inspired by an American fern, RMIT University researchers have developed a prototype that could be the answer to the storage challenge still holding solar back as a total energy solution. The new type of electrode could boost the capacity of existing storage technologies by 3,000%.
Researchers at the University of Maryland have developed a new battery chemistry based on the coupling of a magnesium cathode and an iodine anode. Magnesium batteries have the potential for much higher energy density—roughly 10 times current technology.
A recent study affiliated with UNIST has presented a new cost-efficient way to produce inorganic-organic hybrid perovskite solar cells, which sets a new world-record efficiency performance, in particular photostability.
Results from experiments and computational modeling studies that definitively identify the ‘active site’ of a catalyst commonly used for making methanol from carbon dioxide will guide the design of improved catalysts for transforming this pollutant to useful chemicals.
Scientists at the SLAC National Accelerator Lab and Stanford University have created a small device for hydrogen peroxide production that could be powered by renewable energy sources, like conventional solar panels.
A new class of carbon nanotubes could be the next-generation clean-up crew for toxic sludge and contaminated water, say researchers at Rochester Institute of Technology. Their work applies carbon nanotubes to environmental problems in a specific new way.
VTT Technical Research Centre of Finland has, for the first time, performed all manufacturing stages for a flexible in-molded LED foil in roll-to-roll process. This proves the suitability of the technique for highly cost-effective manufacture of products such as flexible LED displays containing printed electronics.
Lawrence Livermore National Lab researchers, along with collaborators at Worchester Polytechnic Institute, are taking a wholly new approach to metal 3-D printing with a process they call direct metal writing, in which semisolid metal is directly extruded from a nozzle.
The traditional test for assessing the quality of a semiconductor, called the Hall method, measures the number of freely moving charge carriers in a material. But a new, quicker technique makes this measurement by exposing the semiconductor to terahertz light, which shines straight through pure silicon and other semiconductor materials.
Inspired by the fun of playing with Legos, an international team of researchers from Tianjin University of Technology and Harvard University have used the idea of assembling building-blocks to make the promise of next-generation materials a practical reality.
An international collaboration has solved a puzzle about the atomic structure of metallic glasses that has baffled scientists for four decades. Combined measurements revealed that Pd-Ni-P metallic glass has a hidden amorphous phase within a certain temperature range and the thermodynamic inconsistency is the consequence of a phase transition.
Researchers at Aalto University have manufactured artificial materials with engineered electronic properties. By moving individual atoms under their microscope, the scientists were able to create atomic lattices with a predetermined electrical response—bringing ‘designer quantum materials’ one step closer to reality.
When it comes to creating new materials, single crystals play an important role in presenting a clearer picture of a material’s intrinsic properties. A typical material will be comprised of lots of smaller crystals and the grain boundaries between these crystals can act as impediments, affecting properties such as electrical or thermal resistance.
