Anomalous Microwave Emission from Star Forming Regions
Advances in Astronomy, 2013 The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation.

On fermionic vacuum energy [PDF]
arXiv, 2001 We quantitatively compute the rate and spectrum of spontaneous photon emissions, caused by the vacuum decaying when an external magnetic field is introduced. The spectrum of spontaneous photon emissions shows the energy-momentum-dependency in the low-energy region and in the high energy region, is respectively similar to the Rayleigh-Jeans part and the

Direct Natural and Artificial Aging of Aluminum Alloy AlSi10Mg After Laser Powder‐Bed Fusion
Advanced Engineering Materials, EarlyView.Laser powder‐bed fusion of metals aluminum alloy AlSi10Mg has been directly aged. Artificial aging after natural aging is considered. The hardening potential is high for the top part of the samples as well as after short natural aging. The hardening potential is substantially reduced for the bottom part of the samples, as well as after natural aging of

EMISSION OF COMPOSITE PARTICLES IN A CONSTANT ELECTRIC FIELD
East European Journal of Physics, 2015 The spectrum of emission of a composite particle with one degree of freedom in a constant electric field is obtained in the paper. The effectiveness of emission of such particle is compared with the structureless particle having the same parameters.

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Advanced Functional Materials, EarlyView.Transarterial Chemoembolization (TACE) may aggravate liver fibrosis. In this study, a novel oral targeting nanoemulsion is fabricated to enhance the therapeutic effect of antifibrotic drug‐pirfenidone (PFD) on fibrosis after TACE. Studies have shown that PFD nanoemulsion can enhance the oral liver targeting effect of PFD, and effectively improve the ...

Prompt GeV emission in the synchrotron self-Compton model for Gamma-Ray Bursts [PDF]
arXiv, 2008 The detection in 10 bursts of an optical counterpart emission (i.e. during the prompt GRB phase) that is 10-10000 brighter than the extrapolation of the burst spectrum to optical frequencies suggests a synchrotron self-Compton origin for the GRB emission, synchrotron producing the optical counterpart emission.
