Dip Pen Nanolithography® of Silver Nanoparticle Inks for Printed Electronics

Parpia M., Tevaarwerk E., Amro N., Wang H.T., Haaheim J., Rozhok S., Levesque T., Nafday O.A., NanoInk, US

Precision nanoscale deposition of biological, organic, and inorganic materials is a fundamental need in nanoscience research. Dip Pen Nanolithography® (DPN®) is an inherently additive, SPM-based technique, capable of producing nanoscale features with high resolution and [...]

Synthesis and X-ray photoelectron spectroscopy studies of poly(vinyl pyrrolidone) capped gold nanoparticles in a hybrid composite

Mishra A., Tripathy P., Ram S., Fecht H-J., Indian Institute of Technology, IN

Gold nanoparticles are synthesized by direct reduction of an aqueous solution of the metal salt with a surface regulating polymer N-polyvinyl pyrrolidone (PVP), which bind on the gold surface, insulate the particles from Au3+ and [...]

Dispersion and incorporation of optical nanotracers

Samuel J., Raccurt O., Poncelet O., Tillement O., Tardif F., Commissariat à l’Energie Atomique, FR

Silica fluorescent nanoparticles of 40nm diameter are synthesized by a reverse microemulsion process. Numerous industrial applications involve the homogeneous incorporation of nanoparticles into a polymer matrix. Nevertheless, because of their low size, nanoparticles tend to [...]

Enhancement of Oxygen Transfer in Fermentation by Use of Functionalized Magnetic Nanoparticles

Olle B., Bromberg L., Hatton T.A., Wang D.I.C., Massachusetts Institute of Technology, US

Maintaining an adequate oxygen supply to aerobic cell cultures has been a long-standing problem in fermentation technology. Insufficient oxygen transfer rates limit cell growth and ultimately process productivity. Our approach to reducing the oxygen transport [...]

Nanoparticles Formed by Complexation of Poly-gamma-glutamic Acid with Lead Ions

Bodnar M., Kjoniksen A-L, Hartmann J.F., Daróczi L., Nystrom B., Borbely J., University of Debrecen, HU

Recently, reduction of water consumption by industry has been an important challenge. Enhanced ultrafiltration with polymers is a feasible method to remove metal ions from diluted wastewater streams. Biomacromolecules, biodegradable polymers as biomaterials have an [...]
