  摘要：Solid-state Li-S batteries (SSLSBs) are made of low-cost and abundant materials free of supply chain concerns. Owing to their high theoretical energy densities, they are highly desirable for electric vehicles1-3. However, the development of SSLSBs has been historically plagued by the insulating nature of sulfur4,5 and the poor interfacial contacts induced by its large volume change during cycling6,7, impeding charge transfer among different solid components. Here we report an S9.3I molecular c...

• Durable and efficient gene silencing in vivo by hit-and-run epigenome editing AI翻译
  作者：Cappelluti, Martino Alfredo; Poeta, Valeria Mollica; Valsoni, Sara; Quarato, Piergiuseppe; Merlin, Simone; Merelli, Ivan; Lombardo, Angelo

  摘要：Permanent epigenetic silencing using programmable editors equipped with transcriptional repressors holds great promise for the treatment of human diseases1-3. However, to unlock its full therapeutic potential, an experimental confirmation of durable epigenetic silencing after the delivery of transient delivery of editors in vivo is needed. To this end, here we targeted Pcsk9, a gene expressed in hepatocytes that is involved in cholesterol homeostasis. In vitro screening of different editor des...
• Room temperature operation of germanium-silicon single-photon avalanche diode AI翻译
  作者：Na, Neil; Lu, Yen-Cheng; Liu, Yu-Hsuan; Chen, Po-Wei; Lai, Ying-Chen; Lin, You-Ru; Lin, Chung-Chih; Shia, Tim; Cheng, Chih-Hao; Chen, Shu-Lu
  摘要：The ability to detect single photons has led to the advancement of numerous research fields(1-11). Although various types of single-photon detector have been developed(12), because of two main factors-that is, (1) the need for operating at cryogenic temperature(13,14) and (2) the incompatibility with complementary metal-oxide-semiconductor (CMOS) fabrication processes(15,16)-so far, to our knowledge, only Si-based single-photon avalanche diode (SPAD)(17,18) has gained mainstream success and ha...

• Buoyant crystals halt the cooling of white dwarf stars AI翻译

  作者单位：University of Warwick; University of Victoria; Institute for Advanced Study - USA
  摘要：White dwarfs are stellar remnants devoid of a nuclear energy source, gradually cooling over billions of years(1,2) and eventually freezing into a solid state from the inside out(3,4). Recently, it was discovered that a population of freezing white dwarfs maintains a constant luminosity for a duration comparable with the age of the universe(5), signalling the presence of a powerful, yet unknown, energy source that inhibits the cooling. For certain core compositions, the freezing process is pred...
