Fastmarkets Research

Ferro-alloys are alloys of iron and other elements such as vanadium, molybdenum or silicon. They are primarily used in the production of carbon and stainless steel to add elements into molten metal during the steelmaking process. Thus, the main demand driver for ferro-alloys is global steel production levels.

Properties of Graphene – Graphenea

Due to these impressive characteristics, it has been observed that once optical intensity reaches a certain threshold (known as the saturation fluence) saturable absorption takes place (very high intensity light causes a reduction in absorption). This is an important characteristic with …
