The copper plates conducted heat rapidly to and from the bismuth telluride , thus maintaining the temperature difference .
铜片可以把热量迅速地传递到碲化铋上或从碲化铋上导出,这样就能保持气温差。
They work because certain materials , such as bismuth telluride , generate an electrical potential difference within themselves if one part is hotter than another . That can be used to drive a current through an external circuit .
In this article we 'll learn what bismuth oxychloride is , where it comes from , why it is used , and if makeup with it as an ingredient is a good choice for you .
Pepto-bismol ( bismuth subsalicylate ) is technically an antidiarrheal agent that reduces the flow of fluids and reduces inflammation in the intestines and may kill diarrhea-causing organisms there .
Edward sargent , invisage 's chief technology officer and a professor of optoelectronics at the university of toronto , says his firm 's quantum dots are made of metal chalcogenides ( which are a combination of metals such as zinc , indium , bismuth and lead with selenium , sulphur or tellurium ) .
It 's likely that bismuth oxychloride is the reason .
那很可能因为里面含有氯氧化铋。
This scanning tunneling microscope image of a bismuth superconducting compound shows a characteristic checkerboard pattern .
扫描隧道显微镜下铋超导化合物的鲜明棋盘图样。
They work because certain materials , such as bismuth telluride , generate an electrical potential difference within themselves if one part is hotter than another .
它们之所以能起作用是因为某些材料,比如碲化铋,如果其中一部分比另一部分热,内部就会产生电位差。
The second desideratum , of low thermal and high electrical conductivity , was achieved by dividing the bismuth telluride into pellets a few nanometres across .
