Selective heating of multiple nanoparticles as a new strategy for controlled release applications
Utilization of nanoparticle heating for controlled release application was proposed and its feasibility was explored. The proposed method was formulated by realizing that biomolecule - nanoparticle conjugation is heat sensitive and both their dimensions are in the same length scale. This …

A Numerical Model for Thermal Effects in a Microwave Irradiated Catalyst Bed
… analysis is used to determine possibility of selective heating of nanometer-sized, metallic catalyst particles attached to a ceramic support through microwave irradiation. This analysis is incorporated into a macroscopic heat transfer model of a packed and fluidized catalyst bed heated by a …

Dielectric Properties of Minerals and Ores and the Application of Microwaves for Assisted Comminution and Ore Sorting
… while in general, gangue minerals do not. This selective heating leads to differential thermal expansion across phase boundaries and causes microfractures, which can improve liberation and reduce ore competency. During ore sorting, the heat signature is detected using infrared sensors to accept …

Stereoselective synthesis of piperidines
… TMSC1 to give cyclic iminium salts v. Diastereoselective reduction of the iminium salts v with NaBH(OAc)[sub]3 gave piperidines vi which, after cleavage of the chiral protecting group gave the desired enantiomerically-enriched, 2-substituted piperidines vii. [Illustrated] The piperidines vii …

Synthesis and Consolidation of Metal Oxide Nanocrystals via Nonthermal Plasma
… in nonthermal plasmas can be attributed to the selective heating of the particles immersed in the plasma to temperatures well in excess of 1000 K. As a result, nonthermal plasmas are a promising synthesis environment for nanocrystals of high melting point materials, such as many metal oxides. As …

Inline disinfestation of canola seeds from red flour beetles using a 50-ohm RF technology
… A pilot-scale 50-ohm radio frequency (RF) heating system was used to disinfest adult red flour beetles (Tribolium castaneum) in bulk canola seeds (Brassica napus L.) of 9 % moisture content (MC) in a tubular applicator with parallel electrodes. The heating characteristics of the bulk canola …

Fundamental experiments on the response of solutions, polymers, and modified polymeric materials to electromagnetic radiation
… two microwave inactive quartz plates to show selective heating of a 0.002" film. The poly(amide-imide's) dielectric storage and loss values (ɛ', ɛ") were examined as a function of temperature. The metal filled systems showed nonlinear behavior for dielectric loss (ɛ"), magnetic loss (µ"), and …
