Epitaxial Graphene on Metals

In this chapter, we review the recent results on graphene films epitaxially grown on 3d 5d transition-metal surfaces focussing mainly on their atomic structure, aspects of chemical interaction both with the substrate and with adsorbates and the electronic structure of graphene at the interface. We discuss a possibility to prepare sandwich-like structures in the form of intercalates as a possibl...

Action of Metals on Bacteria

Metals and Non-metals

Ductile: Substances that can be drawn into thin wires are called ductile. For example, most of the metals are ductile. Question 2: Why is sodium kept immersed in kerosene oil? Answer: Sodium and potassium are very reactive metals and and combine explosively with air as well as water. Hence, they catch fire if kept in open. Therefore, to prevent accidental fires and accidents, sodium is stored i...

Point defects on graphene on metals.

Understanding the coupling of graphene with its local environment is critical to be able to integrate it in tomorrow's electronic devices. Here we show how the presence of a metallic substrate affects the properties of an atomically tailored graphene layer. We have deliberately introduced single carbon vacancies on a graphene monolayer grown on a Pt(111) surface and investigated its impact in t...

Widely transparent electrodes based on ultrathin metals.

Transparent electrodes made of single-component ultrathin (<10 nm) metal films (UTMFs) are obtained by sputtering deposition. We show that the optical transparency of the deposited films (chromium and nickel) is comparable to that of indium tin oxide (ITO) in the visible and near-infrared range (0.4-2.5 microm), while it can be significantly higher in the ultraviolet (175-400 nm) and mid-infrar...
