A chiral inorganic mesoporous material characterized by having a chiral twisted structure and being mesoporous; a process for producing the material; and a method of using the material. The output driver of the invention receives two differential input signals and outputs a single output signal with low voltage transistors and programmable impedance and on-die termination circuits. Since a very small amount of vapor is needed to form a wet inert gas, the composition of chemical composition will not be significantly affected.
