copper tin alloy 美 英 un.铜锡合金 例句 释义: 全部,铜锡合金
Copper catalysts modified with tin have been demonstrated to be selective for the electroreduction of carbon dioxide to carbon monoxide. However, such catalysts require the precise control of tin loading amount. Here, we develop a copper/tin-oxide catalyst with dominant tin oxide surface being formed...

Alternative routes to the Haber–Bosch process are being sought to electrify ammonia synthesis. Nitric oxide can be electrocatalytically converted into ammonia, but the Faradaic efficiencies and rates of production are currently far below those needed fo
Also composites based on copper–tin alloys containing a solid lubricant have been developed as self-lubricating materials under extreme conditions of load, atmosphere and temperature. It is well known that the addition of graphite serves to reduce friction and wear in copper–tin alloys. However ...
(copper andtin), and nickel silvers (copper, zinc, andnickel, nosilver). There are many useful alloys of copper and nickel, includingMonel; the two metals are completely miscible. Copper also forms an important series of alloys withaluminum, calledaluminum bronzes.Berylliumcopper (2 percent Be...
