Logitech today is announcing the next phase of its pro gaming headset lineup, the G Pro X 2. And boy oh boy does it bring with it some notable advancements. And there are quite a few of them. Of course you’ll notice that the new headset doesn’t really look any different from the last model. It has the same general design as the G Pro X. And that’s intended. Logitech said it was solely focused on only making changes where it felt things could improve. The visual design of the headset was not one of them. Although it did…

Logitech is announcing a new G Pro X 2 Lightspeed gaming headset today that features graphene audio drivers. You’ve probably heard of graphene, the miracle form of carbon that has been promised by many over the past 20 years to change the world of technology. While we haven’t seen graphene used to create space elevators or make the internet run faster just yet, Logitech is using it to create headphone drivers that are lightweight.“With our use of graphene, we can create a driver that is both incredibly rigid and, at the…

By Center for Research in Biological Chemistry and Molecular Materials (CiQUS) May 2, 2023In a significant development, researchers have created a new graphene nanostructure with adjustable properties by connecting graphene strips using adaptable “bridges.” This discovery has the potential to influence quantum computing and renewable energy applications.Scientists from CiQUS, ICN2, University of Cantabria, DIPC and DTU join forces to develop a versatile method for building brick-by-brick carbon nanocircuits with tunable…

In a recent publication in Nature, researchers have discovered record-high magnetoresistance in graphene under ambient conditions. The team utilized high-quality graphene in its intrinsic state, creating a plasma of fast-moving Dirac fermions that demonstrated a surprisingly high mobility despite frequent scattering. This discovery of giant magnetoresistance could help solve longstanding mysteries surrounding strange metals and linear magnetoresistance. The potential applications of this finding span various industries,…

A team of researchers led by Northwestern University and the University of Texas at Austin (UT) have developed a novel graphene heart implant that’s about the thickness of a strand of hair and monitors and corrects abnormal heart rhythms using light.Heart rhythm disorders – cardiac arrhythmias – are caused by faulty electrical signaling in the heart, causing it to beat too quickly or too slowly. In some cases, this can lead to heart failure, stroke, and even sudden death.Cardiac arrhythmias are commonly treated with…

Graphene is a special material. Among its many talents, it can act as a superconductor, generate a super-rare form of magnetism, and unlock entirely new quantum states.Now graphene has another amazing credit: it can record levels of magnetoresistance without a need to push the temperature down towards absolute zero.High magnetoresistance – a material's ability to change its electrical resistance in response to a magnetic field – is relatively rare, yet materials that can shift their properties in this fashion are useful…

When we think of graphene, we tend to think of its use in high-profile applications such as electronics, medical devices and construction materials. Now, however, it's been incorporated into an additive which reportedly boosts the performance of humble plastic film.Widely hailed as a "wonder material," graphene takes the form of one-atom-thick sheets of carbon atoms linked to one another in a honeycomb pattern. Along with being the world's strongest human-made substance, it's also very flexible, stretchable and chemically…

Scientists have found that nanoripples in graphene make it a strong catalyst, even though it was expected to be chemically inert. Their research, published in PNAS, demonstrated that nanoscale corrugations on graphene’s surface accelerate hydrogen splitting as well as the best metallic-based catalysts, and this effect may be present in all 2D materials.A team of researchers led by Prof. Andre Geim from the National Graphene Institute (NGI) have discovered that nanoripples in <span class="glossaryLink"…
