一種新型化合物,可在室溫下受控切換導體與絕緣體

一種新型化合物,可在室溫下受控切換導體與絕緣體 金屬導體與絕緣體本來是站在天秤兩端的材料,然而研究人員現在發現一種錳和硫化物的化合物,只要改變壓力就能在室溫下自由切換導體與絕緣體身分。 材料的導電性能取決於電子通過它的難易程度,導體、半導體和絕緣體的差別在於能隙,導體幾乎沒有能隙,絕緣體能隙高得令人生畏,半導體則介於兩者之間。 而羅徹斯特大學機械工程學家 Ranga Dias 團隊在尋找硫化物與其他材料的搭配時,發現錳和硫化物的化合物 MnS2 存在一種新型電荷轉移機制。剛開始 MnS2 是軟絕緣體,但隨著研究人員施加壓力,MnS2 會轉變為可導電的金屬狀態,奇怪的是隨著壓力進一步增加,MnS2 又會在某個臨界點再次變回絕緣體,這種情況非常罕見。 團隊於是開始檢查該過程中材料內部發生了什麼事,發現在絕緣

Study shows COVID-19 organ-specific outcomes depend on anti-spike glycoprotein antibodies

Study shows COVID-19 organ-specific outcomes depend on anti-spike glycoprotein antibodies A recent study from the University of Rochester reveals how the biodistribution kinetics and the affinity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for many different organs in the human body can be affected by antibodies targeting viral spike glycoprotein. The paper is currently available on the bioRxiv preprint server while it undergoes peer review. The ongoing coronavirus disease 2019 (COVID-19) is caused by the SARS-CoV-2, a virus that can enter host cells by using its spike glycoprotein to bind with the angiotensin-converting enzyme 2 (ACE2) receptor widely distributed in tissues and organs.
