Interesting applications on a novel high pressure high temperature microfluidic-based flow reactor

Niesz K., Csajagi Cs., Bernadett B., Jones R., Darvas F., ThalesNano, HU

Performing hazardous reactions at high pressure and high temperature in a safer and faster manner have always attracted great attention in the chemical industry. Recently, a new member of the Thales CubeTM micro-flow reactor series [...]

Nano-Biotechnology toward Diagnostic Industry: Obstacles and Opportunities

Esfandyarpour H., Stanford, US

Biosensing of infectious agents should be ideally real-time, multiplexed, sensitive and specific. While no single device thus far have demonstrated superiority with respect to all these qualities, many of the upcoming nanomaterial-based sensors described in [...]

Assemblies of Blue-emitting CdSe Nanocrystals in Redox Copper Phenanthroline-based Polymeric Chains

Fu S.-J., Lin K.-J., National Chung Hsing University, TW

Assemblies of quantum-confined semiconductor nanoparticles into block copolymer micelles and silica shell open the door to “tunable” optical, electrical, and even mechanical properties. Sharp tuning of 3D spherical morphology in water solution is a fascinating [...]

Transforming nano-science to nano-technology: Manipulating the size, shape, surface morphology, agglomeration, phases and defects of silver nano-particles under continuous flow conditions

Iyer S., Raston C.L., Saunders M., The University of Western Australia, AU

Spinning disc processing (SDP) is an instantaneously scalable, continuous flow and high throughput flash nano-fabrication technology which embraces green chemistry metrics. It has been used to prepare silver nano-particles with remarkable control in size (5 [...]

Poly(acrylic) acid-coated Silver Nanoparticles for Antibacterial Textile Finishing

Falletta E., Bonini M., Fratini E., Lo Nostro A., Lo Nostro P., Becheri A., Lo Nostro A., Lo Nostro P., Baglioni P., University of Florence, IT

The synthesis of silver nanoparticles was obtained through two different methods and using different poly(acrylic) acids as templating agents. Cotton, wool, and polyester fabrics were treated with the nanoparticles, and their antimicrobial performances were tested [...]

Low-Temperature Polyol Synthesis of Nanocrystalline Co and CoPt Alloys

Chávarri-Pajares E., Pérez J., Perales-Perez O., Singhal R., Tomar M.S., University of Puerto Rico, PR

The strong size-dependent magnetic properties of transition metal nanocrystals can be used to estimate the scaling limits of magnetic storage, a key component of information technology. High Ku (magnetocrystalline anisotropy constant) materials become then very [...]

Synthesis and Characterization of Magnetite Powders

Silverman B.M., Parasher S., Milner B., Zhou B., Headwaters Technology Innovation Group, US

Low-cost magnetic powders have been synthesized by Headwaters Technology Innovation Group. These powders exhibit a strong magnetic susceptibility mainly due to magnetite formation. The potential applications for this product range from cancer treatment, ferrofluids, to [...]

Magnetic characteristics of FePt nanodots formed by a self-assembled nanodot deposition method

Yin C.K., Choi H., Bea J.C., Murugesan M., Yoo J-H, Fukushima T., Murakami Y., Tanaka T., Shindo D., Miyao M., Koyanagi M., Tohoku University, JP

FePt nanodot with L10 fct structure has attracted considerable attention owing to its potentials for new applications. FePt nanodots dispersed in a SiO2 film (FePt nanodot film) were formed by a self-assembled nanodots deposition (SAND) [...]

Magnetic Properties of Multi- and Sigle-Domain Particles of CuxNi1-xFe2O4 Ferrites

Msomi J.Z., Moyo T., University of the Free State, ZA

The crossover effect from multi- to single-domain particles on the magnetic properties of CuxNi1-xFe2O4 oxides due to grain size reduction to nanometre scale is investigated. The properties of the bulk and nanosized oxide have been [...]

Slurry sample injection for determination of ferrite nanocolloids chemical composition by ICP spectrometry

Sousa M.H., Lins E.S., Tourinho F.A., Depeyrot J., Martins W.D., Zara L.F., Castro C.F.S., de Castro G.R., Universidade de Brasilia, BR

In the biomedical field, some applications of nanomaterials require dynamically quantifying them in blood and tissues probes. Nevertheless, the usual methods which are employed to titrate the nanoparticles require their dissolution before the chemical analysis, [...]
