A New Sonochemical Synthesis Route for Silicon Nanoparticle Inks for Energy and Nanomedical Applications

Cádiz Bedini A.P., Chen C., Klingebiel B., Notten P.H.L., Rau U., Forschungszentrum Jülich, DE

Silicon nanoparticles (Si-NPs) have become increasingly relevant in several important fields ranging from solar cells, next-generation quantum dot LEDs, lithium-ion batteries, and because silicon is biodegradable, their use as drug carriers or fluorescent markers has [...]

Photoswitching Nanoparticles Enable Innovative Bioimaging Technologies

Wan W., Li A., Washington State Universoty, US

Nanoparticles have evolved to be the carriers of multiple technologies, which garnished unprecedented power in molecular imaging. For example in bioimaging, a single fluorescent probe is usually lost in the ocean of myriad other molecules [...]

Highly luminescent Ca3Sc2Si3O12:Ce3+ silicate garnet nano- and microparticles with 50-70% photoluminescence quantum yields as efficient phosphor converters for white LEDs

Levchuk I., Schröppel F., Römling L., Osvet A., Khaidukov N., Zorenko Y., Van Deun R., Batentschuk M., Brabec C.J., University of Erlangen-Nuremberg, DE

Solid state lighting based upon a combination of violet/blue light emitting diodes (LEDs) and a phosphor converter created enormous commercial interest because of the potentially higher efficacies and long lifetimes of these light sources. Most [...]

Inkjet printing of carbon nanospheres

Orrill M., Abele D., Banek N., Wagner M., LeBlanc S., The George Washington University, US

Proposed applications of drop-on-demand (DOD) inkjet printing extend beyond printing of text and graphics to include rapid manufacturing of thin electrical devices. The most commonly printed electronic materials are silver nanoparticles due to their potentially [...]

Numerical Analysis of Acoustophoretic Discrete Particle Focusing in Microchannels

Karampelas I.H., Gómez-Pastora J., Cowan M.J., Bringas E., Ortiz I., Furlani E.P., Flow Science Inc., US

Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel [1]. The process is inherently general and can be readily extended for multiple [...]

Carcinoma cellular uptake, imaging, and targeting by RGDS- and TAT-conjugated upconversion and/or magnetic nanoparticles

Horák D., Kostiv U., Proks V., Jirák D., Institute of Macromolecular Chemistry AS CR, CZ

Specific targeting and in vivo visualization of cancer cells is of crucial importance for early detection and treatment of cancer. We have developed monodisperse poly(ethylene glycol) (PEG)-modified SiO2-coated Fe3O4 superparamagnetic nanoparticles [1] with size tuned [...]

Continuous Production of Polymer Coated Drug Crystals, Particles and Nanoparticles by Hollow Fiber Membrane-based Cooling Crystallization and Anti-solvent Crystallization

Sirkar K., Chen D., Singh D., Jin C., Pfeffer R., New Jersey Institute of Technology, US

Polymeric coating can provide protection for fragile drugs from hydrolysis and degradation. With an appropriate polymer coating, nanoparticles are known to traverse the physiological human mucous barrier. Such coatings are also integral to controlled drug [...]

Development of alumina/iron oxide nanocomposites as adsorbents for arsenic and fluoride removal from aqueous solutions: Process Optimization

Prathna T.C., Kumar Sharma S., Kennedy M., UNESCO-IHE, NL

The study was designed to optimize the process for the synthesis of alumina/ iron oxide nanocomposites and to investigate their potential as a sorbent to remove fluoride and arsenic from contaminated water. The nanocomposites had [...]

Study of a Power Source Based on Low Energy Nuclear Reactions (LENRs) Using Hydrogen Pressurized Nanoparticles

Miley G.H., University of Illinois, US

We are studying anomalous heat, attributed to Low Energy Nuclear Reactions (LENRs), generated from metal alloy nanoparticles loaded with hydrogen (or deuterium) through pressurizing the vessel containing the particles [1]. The primary result thus far [...]

Production of Bioabsorbible Nanoparticles of Polycaprolactone by Using a Recirculating System

Colmenares G., Agudelo L., Pinal R., Hoyos L., Universidad Pontificia Bolivariana, CO

Encapsulation and controlled release of substances using polymeric nanoparticles require that these have a high reproducibility, homogeneity, and control over their properties, especially when they are to be used in medical, pharmaceutical or food applications [...]
