Copper Displacement Deposition on Nanostructured Porous Silicon

Bandarenka H., Redko S., Nenzi P., Balucani M., Belarusian State University of Informatics and Radioelectronics, BY

In the present work we have demonstrated nanosized structures fabrication by the copper displacement deposition on electrochemically etched porous silicon. Peculiarity of such method is the convergence of copper reduction with porous silicon dissolution. Principal [...]

Rapid Fabrication of Nanofibrous Membranes inside microchannels using Femtosecond Laser Micromaching

Tavangar A., Tan B., Venkatakrishnan K., Ryerson University, CA

In this paper, we propose a single-step technique to develop membrane-based microfluidic channels using femtosecond laser micromachining. The proposed method fabricates both the nanoporous membrane and microfluidic channel in a single step under ambient condition. [...]

Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]
