Multi-scale and multi-physics approach to understand the microstructure growth mechanism of Al and Ni based alloys.

A reactive seed layer can be created on the 2D surface without perturbing the electronic properties of the 2D substrate for depositing a thin layer of dielectrics uniformly on the functionalized 2D surface for designing low power electronic devices (such as super-capacitor and field effect transistor (FET)) and high energy conversion thermoelectric devices.

 

Anhydrous proton exchange fuel cells membrane will have significant advantages over conventional proton exchange membranes because fast proton transport can take place at relatively high temperatures in the complete absence of water.

STM and DFT results show that functionalization of graphene with MPc would be a potential candidate for chemical sensing platforms, which can be expected to show high chemical sensitivity. NO/CuPc/HOPG, negative charge is transferred from graphene to NO, and there is a large decrease of DOS in graphene around 1 eV below the Fermi surface in the valence band. This altered DOS of graphene induces a decreased binding energy for NO chemisorption in neighboring sites consistent with low saturation coverage. However, even though the saturation coverage of NO/CuPc/graphene is low, the electronic structure of graphene can be highly altered, because of very low density of states of graphene.

Advanced sorbent materials (alkali metal doped SWNTs and HOPG) can act as chemically reactive highly dispersed sorbents that irreversibly break C—Cl bonds in chloroalkanes anchoring the alkyl groupp on the carbon surface at defect sites of SWNTs and both basal plane of HOPG. This finding could prove useful for capturing and detoxification of toxic chemicals agents and toxic industrial compounds with other key functional groups (e.g. CN, —C—S—C—, P=O) on high area advanced carbon sorbents, and also opens up new potential area of research using functionalized metal surfaces.
