Graphene semiconductors mark new start

» We have just started 2024 and there are already exciting announcements. The clever people at Georgia Tech in Atlanta have built the first scalable semiconductor using a graphene base. Graphene, a wonder product, is not a scalable semiconductor on its own, so they bonded silicon carbide, or what we call carborundum, to a layer of graphene creating the necessary bandgap to have a working switch. A switch means binary and from there they can make wafers like those currently used in the chip manufacturing process to make CPUs and other devices.
Huawei still some way behind rivals

» I've had some feedback expressing surprise that I invested in a smartwatch. Yes, I didn't think I'd see the day either, but it does function very well as a watch with changeable faces and at a price point that's far below some of the faces it can duplicate. The always-on test was a success in that I only turned the watch off when I wasn't using it on some evenings. It also does sleep tracking, which perhaps provides a sterner test, but it still provided a week's worth of use making it usable for many. On a longer trip you would need to take the charger along. Note that for both tests, I kept Bluetooth on the whole time.
