Field-Limited Digestive Ripening for Self-Organization of Thiol-Capped Gold Nanoparticles
It is known that the nearly monodisperse gold particles of nanosizes could be prepared by using digestive ripening. Based on the assumption of charged particles, the model for expressing the digestive ripening has been proposed. [...]
Gaseous Nanobubbles – Surface Nanopatterning Elements
Gaseous nanobubbles adhering to solid surfaces immersed in de-ionized water were found to exhibit interfacial forces capable of nanopatterning hydrophobic surfaces at mild conditions. Random and net-like periodic nanopattern imprinted in polymeric film represent images [...]
Numerical Analysis of Laser Induced Photothermal Effects using Colloidal Plasmonic Nanostructures
Colloidal plasmonic nanostructures are finding increasing use in a variety of applications that range from nanoparticle synthesis to bioimaging to medical therapy. In many such applications, a pulsed laser is used to heat plasmonic nanostructures [...]
A structural analysis of olive oil organogelation
Filippelli L., Gentile L., Lupi F.R., Rossi C.O., Baldino N., Ranieri G.A., Gabriele D., University of Calabria, IT
Organogels based on liquid vegetable oils are possible replacers of saturated or hydrogenated fats in the food industry. There is still a lack of information about the link between macroscopic parameters and material microstructure. By [...]
Acoustic – Electromagnetic Transformation in Magnetic Nanofluids
Here is examined the acoustic – electromagnetic transformation accompanying the propagation of sound wave through a magnetic nanofluid.The magnetic nanofluid was placed in the cylindrical resonator. An external magnetic field was applied along an axis [...]
Microstructures design of the assembly of monodisperse polystyrene microspheres via alternative current electric field
The assembly of monodisperse polystyrene microspheres under alternative current electric field was applied as a model system to study the assembling mechanism for nanomaterials. The microspheres of about 1-2 μm in diameter enable us to [...]
Thermo-plasmonics in self-organized materials
De Sio L., Placido T., Comparelli R., Curri L., Tabiryan N., Bunning T., Beam Engineering for Advanced Measurements Company, US
Conversion of near infrared radiation into heat, controlled at the nanoscale, is achieved and detected by exploiting the localized plasmonic resonance (LPR) of gold nanorods (GNRs) trapped in thermosensitive self-organized materials such as Liquid Crystals [...]
Bulk-Size Transparent Gadolinium Oxide-Polymer Nanocomposites for Gamma Ray Scintillation
Chen Q., Cai W., Hajagos T., Kishpaugh D., Liu C., Cherepy N., Dooraghi A., Chatziioannou A., Payne S., Pei Q., University of California, Los Angeles, US
Heavy element loaded polymer composites have long been proposed to detect high energy X- and -rays upon scintillation. The previously reported bulk composite scintillators have achieved limited success because of the diminished light output resulting [...]
Formation of complex nanoparticles from a spherical protein (BSA) and two polycations (PDL with two molecular weights) using coacervation method of the polyelectrolytes
Complex nanoparticles (CNPs) were formed by mixing Bovine Serum Albumin (BSA) and Poly-D-Lysine with low (LMW-PDL) and high molecular weights (HMW-PDL). Since BSA and both PDL biopolymers in neutral and alkaline pHs are oppositely charged [...]
