Discovery of GeV emission from the direction of the luminous infrared galaxy NGC 2146
, 2014 Recent detection of high-energy gamma-ray emission from starburst galaxies M82 and NGC 253 suggests that starburst galaxies are huge reservoirs of cosmic rays and these cosmic rays convert a significant fraction of their energy into gamma-rays by ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications
FEBS Open Bio, EarlyView.This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Cathodo- and radioluminescence of Tm$^{3+}$:YAG and Nd$^{3+}$:YAG in an extended wavelength range [PDF]
, 2017 We have studied the cathodo- and radioluminescence of Nd:YAG and of Tm:YAG single crystals in an extended wavelength range up to $\approx 5\,\mu$m in view of developing a new kind of detector for low-energy, low-rate energy deposition events. Whereas the

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Yarns Emitting Far Infrared Rays
International Journal of Computational and Experimental Science and Engineering, 2018 Infrared radiation refers to electromagnetic radiation whose wavelength is longer than visible light, but shorter than terahertz and microwave radiation. Far infrared radiation (FIR) denotes radiation that is considered a kind of infrared radiation and includes wavelengths between 5.6-1000 micron.
