A team of researchers led by Director Rod Ruoff at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS), including graduate students at the Ulsan National Institute of Science and Technology (UNIST), have achieved growth and characterization of large area, single-crystal graphene that has no wrinkles, folds, or adlayers. It…

In the search for sustainable energy storage, researchers at Chalmers University of Technology, Sweden, present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world’s most common and cheap metal ions — sodium. The results show that the capacity…

Intrinsic barrier in chargingAl-ion batteries earned their fame by using an organic cation-based electrolyte1,5, similar to those cases in lithium13 and lithium-ion batteries14. Different from metal salts in water, cations here do not have any metal element; therefore, they don’t directly participate in redox reactions. Instead, the metal ions exist as anions or as negatively…

Synthetic graphite plays a significant role in a few highly specialized industries. Here’s a look at what it is and why investors should know about it. Synthetic graphite is a unique material that is often used in metal manufacturing and in energy devices such as batteries and solar panels. Synthetic graphite is comprised of high-purity…

The iconic Prestige Midplus gets a major overhaul for 2020! Boasting a new mold with a thinner beam and reengineered sweetspot, this traditional player’s racquet is stable without being unwieldy. With its thin 20mm beam, arm-friendly flex (61RA) and dense 18×20 string pattern, this update lives up to its Prestige pedigree – think best of…

Benefiting from their unique physicochemical properties, graphene derivatives have attracted great attention in biomedicine. In this study, we carefully engineered graphene oxide (GO) as a vaccine adjuvant for immunotherapy using urease B (Ure B) as the model antigen. Ure B is a specific antigen for Helicobacter pylori, which is a class I carcinogen for gastric…
