Nonthermal plasmas can produce high quality nanocrystals in a continuous process without requiring solvents. A nonthermal plasma process is demonstrated to synthesize stoichiometric Cu2S nanocrystals, which show no signs of oxidation by spectrophotometry after 2 months in the ambient when stabilized with oleylamine and dispersed in toluene.

We explicitly calculate nonthermal gravitino production during the preheating period in the inflationary Universe. Contrary to earlier investigations, we consider a two-field model to separate the mechanisms of supersymmetry breaking and inflation. We show that the superpartner of the inflaton is significantly generated, while the gravitino production is considerably smaller. Nonthermal product...

OBJECTIVE To present the frequency resonance hypothesis, a possible mechanical mechanism by which treatment with non-thermal levels of ultrasound stimulates therapeutic effects. The review encompasses a 4-decade history but focuses on recent reports describing the effects of nonthermal therapeutic levels of ultrasound at the cellular and molecular levels. DATA SOURCES A search of MEDLINE from...

Nonthermal radio emission in the galactic center reveals a number of vertical structures across the galactic plane, which are attributed to poloidal magnetic field and/or energetic outflow. Thermal radio emission comprises star forming regions distributed in a thin, dense thermal gas disk. The thermal region is associated with dense molecular gas disk, in which the majority of gas is concentrat...

X-ray observations of galaxy cluster merger shocks can be used to constrain nonthermal processes in the intracluster medium (ICM). The presence of nonthermal pressure components in the ICM, as well as the shock acceleration of particles and their escape, all affect shock jump conditions in distinct ways. Therefore, these processes can be constrained usingX-ray surface brightness and temperature...

Dust acoustic solitary waves are studied in warm dusty plasma containing negatively charged dusts, nonthermal ions and Boltzmann distributed electrons. Sagdeev pseudopotential method is used in order to investigate solitary wave solutions in the plasmas. The existence of compressive and rarefractive solitons is studied. Keywords—Nonthermal, Soliton, Dust, Sagdeev potential

Data are presented from the EISCAT (European Incoherent Scatter (Facility)) CP-3-E experiment which show large increases in the auroral zone convection velocities (> 2 km s -1 ) over a wide range of latitudes. These are larger than the estimated neutral thermal speed and allow a study of the plasma in a nonthermal state over a range of observing angles. Spectra are presented which show a well-d...

We discuss models of energetic particle acceleration, interactions and nonthermal emission in active starforming regions at different stages of their evolution. Powerful stellar winds and supernova explosions with intense energy release in the form of strong shock waves can convert a sizeable part of the kinetic energy release into energetic particles. The starforming regions are argued as a fa...

We report on a nonthermal mechanism for counterion partitioning driven by dielectric contrasts in a charged system. This mechanism allows objects to remain charged even in very low dielectric mediums and at low temperatures, if a nearby high dielectric environment can host its counterions. This nonthermal counterion partitioning leads to an attractive counterion pressure that is usually much la...
