Chemical functionalization of silicon oxide (SiO2) surfaces with silane molecules is an important technique for a variety of device and sensor applications. Quality control of self-assembled monolayers (SAMs) is difficult to achieve because of the lack of a direct measure for newly formed interfacial Si−O bonds. Herein we report a sensitive measure of the bonding interface between the SAM ...

Aluminum processing - Aluminum processing - Ores: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic and ductile metal in the boron group . By mass, aluminium makes up about 8% of the Earth's crust, where it is the third most abundant element (after oxygen and silicon) and also the most abundant metal. Occurrence of aluminium .

Chromium is a chemical element with the symbol Cr and atomic number 24. It is the first element in group 6.It is a steely-grey, lustrous, hard and brittle transition metal. Chromium is the main additive in stainless steel, to which it adds anti-corrosive properties.Chromium is also highly valued as a metal that is able to be highly polished while resisting tarnishing.

The problem is that the basic battery design hasn't changed since Sony released its rechargeable lithium-ion (li-ion) cell way back in 1991. The li-ion is a great battery. It powers most of our devices, as well as the burgeoning electric car industry. But you're still talking about a technology that is nearly 30 years old.
