Voju Gigabyte debuts new GeForce GTX 970 Twin Turbo 4GB
An image depicts a sample of rebar graphene after testing under an electron microscope by materials scientists at Rice University. It shows how cracks propagate in a zigzag way, rather than straight, as would be seen in plain graphene. The rebar graphene is attached by molecular forces on both sides to a

adidas samba donna e-resistant ldquo rebar graphene rdquo is more than twice as tough as pristine graphene.Graphene is a one-atom-thick sheet of carbon. On the two-dimensional scale, the material is stronger than steel, but because graphene is so thin, it is still subject to ripping and tearing.Rebar graphene is the nanoscale analog of rebar (reinforcement bars) in concrete, in which embedded steel bars enhance the material rsquo s strength and durability. Rebar graphene, developed by the Rice lab of chemist James Tour in 2014, uses carbon nanotubes for reinforcement.

AMD has launched Radeon Pro W5700, its first 7nm RDNA-based professional graphics cardThe new AMD Radeon Pro W5700 professional graphics card is based on the 7nm Radeon DNA GPU architecture. AMD intends to replicate its success with the consumer graphics card market segment with the release of this new Radeon professional graphics card.The card features 36 compute units, 2,304 stream processors. According to its rated performa
air max 720 nce, the card is positioned to take over the incumbent Polaris-based Radeon Pro WX 7100, which is considered a high-end graphics card in the AMD Radeon Pro GPU series.The AMD Radeon Pro W5700 is about 55% better than the WX 7100, in terms of floating point operations. According to AMD, due to the card rsquo s new RDNA GPU architecture, it delivers up to 25% higher performance per clock, and up to 41% higher average performance-per-watt than the previous-gen GCN
