微软发布 MatterGen: 利用 Diffusion Model 实现材料设计

“MatterGen 是一种在材料的三维几何上运行的扩散模型,在 MP 和 Alex 数据库中训练了 60 万种稳定材料。图 3 中, MatterGen 可以持续生成更多新颖候选材料。相比之下,基线早就耗尽候选而停滞。

与 ImgGen 类似,扩散模型通过调整随机结构的位置、元素和周期性晶格来生成建议的结构。并且可以微调以在不同设计要求下生成材料,如特定化学、晶体对称性或偏好供应链安全元素。

通过与中科院 SIAT 团队合作合成了一种新型材料 TaCr2O6,其结构由 MatterGen 在设定弹性模量为 200 GPa 下生成,实验测得为 169 GPa,相对误差低于 20%,从实验角度来看非常接近。”

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.
