Biological synthesis of copper nanoparticles using plant extract

Lee G., Lee H.J., Lee G., Lee H.J., Jang N.R., Yun J.H., Song J.Y., Kim B.S., Chungbuk National University, KR

Copper nanoparticles were biologically synthesized using plant leaf extract as reducing agent. On treatment of aqueous solutions of CuSO4•5H2O with leaf extract (Magnolia), stable copper nanoparticles were formed. UV-vis spectroscopy was used to monitor the [...]

Functional nanowire microscopy tip

Kim J., Shin Y-H, Yun J.H., Han C-S, Hyun M.S., Korea Institute of Machinery and Materials (KIMM), KR

Excellent electric conductive nickel silicide (NiSi) nanowire (NW) was aligned on a conventional Si tip and performed as an electric force microscopy (EFM) probe. Single crystalline structured NiSi NW was grown in plasma-enhanced chemical vapor [...]

Electrokinetic Flows in Highly Charged Micro/Nanochannel with Newtonian Boundary Slip Condition

Chun M.-S., Yun J.H., Kim T-H., Korea Institute of Science and Technology (KIST), KR

The physics of micro/nanofluids has become an area of intense interest both scientifically and technologically. The long-range nature of viscous flows and the small dimension inherent in confined spaces imply that the influence of boundaries [...]
