Atomic Layer Deposition (ALD) Modified Membrane Systems for Desalination

BACKGROUND Only a few studies were reported on the ALD modified inorganic membranes for desalination. Alam et al. grew TiO2 ALD on polyethersulphone (PES) membrane. It was shown that the TiO2-film deposited PES membrane exhibited >90% NaCl rejection (4 times higher than uncoated membranes) in a pressurized desalination at feed pressure of 8 atm...

Fabrication of Large Area Gold-based Metalenses

BACKGROUND Surface plasmons (SP) and surface plasmon polaritons (SPP) are nonlinear 36 many-body excitations that couple light with the electron density of states of a material, in 37 particulars, metals. The nonlinear nature of SP and SPP can be used for frequency doubling of 38 light (second harmonic generation) and the formation of evanescent...
