Some weak motions chosen test...
The selective ion penetration and water purification properties of freestanding graphene oxide (GO) membranes are demonstrated. Sodium salts permeated through GO quickly, whereas heavy-metal infiltrated much more slowly. Interestingly, copper were entirely blocked by membranes, organic contaminants also did not infiltrate. mechanism the ion-penetration is discussed. nanocapillaries formed within responsible for permeation metal ions, coordination between ions with restricted passage ions....
A graphene/n‐type silicon (n‐Si) heterojunction has been demonstrated to exhibit strong rectifying behavior and high photoresponsivity, which can be utilized for the development of high‐performance photodetectors. However, graphene/n‐Si photodetectors reported previously suffer from relatively low specific detectivity due large dark current. Here, by introducing a thin interfacial oxide layer, current reduced two orders magnitude at zero bias. At room temperature, photodetector with exhibits...
