Formation mechanism of copper-silver metal nanoparticle encapsulated in carbon shell

Kang H.Y., Wang H.P., Huang C.H., Tsai C.K., National Cheng Kung University, TW
The formation mechanism of nanosize copper-silver encapsulated in the inert carbon shell (CuAg@C) has been studied by in-situ small angle X-ray scattering (SAXS) spectroscopy. SAXS is a very useful method in studies of electron density [...]

Cleaning 10nm ceramic particles by the supersonic particle beam

Kim I., Hwang K., Lee J.W., POSTECH, KR
Cryogenic aerosol beam using micron-sized aerosol particles has long been successfully used to remove contaminant particles down to 50nm, and supersonic particle beam using particles smaller than 100nm lowered the limit of cleaning down to [...]

Synthesis of highly-doped silicon and germanium nanoparticles in a low-pressure plasma-reactor for thermoelectric and solar applications

Grimm H., Petermann N., Gupta A., Wiggers H., University of Duisburg-Essen, DE
Microwave-plasma induced thermal decomposition of gaseous precursors like germane (GeH4) and silane (SiH4) is used to synthesize semiconductor nanoparticles for thermoelectric and thermal applications. P and n-doping can be achieved by mixing silane and germane [...]

Ultrasonically sprayed nanostructured SnO2 thin films for highly sensitive hydrogen sensing

Patil L.A., Pratap College Amalner, IN
Nanostructured SnO2 thin films were prepared by ultrasonic spray pyrolysis technique. The aerosol produced by nozzle was sprayed on glass substrate heated at 150oC. The sensing performance of the films was tested for various gases [...]

Electron instabilities in nanoclusters, nanostructures and inhomogeneous nanomaterials: bottom up approach

Kocharian A., California State University Los Angeles, US
Inhomogeneous nanomaterials with strong local electron correlations are creating a new world-view in condensed matter physics [1-4]. These materials with intrinsic ihomogeneities have electronic and magnetic properties that are widely different from the conventional materials. [...]

Au nanoparticles functionnalized by J-aggregates for highly efficient strong coupling applications

Djoumessi Lekeufack D., Brioude A., Bellessa J., De Zeng L., Coleman A.W., Miele P., Université Claude Bernard-Lyon 1, FR
The coupling of organic molecules and metallic nanostructures brings new opportunities to develop highly efficient photonic devices that combine the best features of those two specific materials. Indeed, the interactions between the electronic transitions of [...]

Surface Enhanced Raman Utilizing Magentic Core Silver Shell Nanoparticles

Glaspell G.P., UACE ERDC, US
SERS is an extremely sensitive technique exploited in laboratory investigations to provide single molecule detection. In sensor applications, this sensitivity has not been fully realized in part due to the low scattering efficiency. We hypothesize [...]

Nano Silver – Why It is so Hot Now?

Lem K.W., Haw J.R., Lee D.S., Brumlik C., Sund S., Curran S., Smith P., Brauer S., Schmidt D., Konkuk University, KR
It has been known for centuries that silver has an antiseptic effect. In ancient times, many Greeks used silver vessels for drinking water storage. Koreans have also chosen silver to make their metal chopsticks. Recently, [...]

Durability of Pt/MWCNT Nanocatalyst in High Temperature H3PO4/PBI PEMFC

Buazarand F., Khaledib H., Almoora K., Lia Q., Steenbergc T., Jensen J.O., Bjerruma N.J., technical university of denmark(DTU), DK
The newest development in the field of proton exchange membrane fuel cells (PEMFC) aims at higher operational temperatures above 100˚C [ ] which have been the main research focus at the Energy and Materials Science [...]

New ripening mechanism for silver and gold nanorods in aqueous solution

Segets D., Damm C., Yang G., Spiecker E., Peukert W., Friedrich-Alexander University, DE
In the last years an increasing number of publications addressed the relationship between particle shape and the electro-optical product properties. Especially anisotropic metal particles e.g. gold or silver were found to be promising candidates as [...]
