LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF ETHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS

open access: yesRevista UniVap, 2023
Here we present experimental results on the irradiation of ethanol ice (CH3CH2OH) by broadband soft X-rays to simulate the effect processing of organic-rich astrophysical ices by space radiation.

Far Infrared Rays Drying Characteristics of Tissue Cultured Mountain Ginseng Roots

open access: yes, 2009
This study was conducted to investigate the drying characteristics of tissue cultured mountain ginseng roots. The far infrared rays dryer of a double blast system used for this experiment can control the drying parameters such as far infrared heater ...

Hot accretion flow in black hole binaries: a link connecting X-rays to the infrared [PDF]

open access: yes, 2012
Multiwavelength observations of Galactic black hole transients have opened a new path to understanding the physics of the innermost parts of the accr etion flows. While the processes giving rise to their X-ray continuum have been studied extensively, the

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced 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 ...

Remote Optogenetics Using Up/Down-Conversion Phosphors

open access: yesFrontiers in Molecular Biosciences, 2021
Microbial rhodopsins widely used for optogenetics are sensitive to light in the visible spectrum. As visible light is heavily scattered and absorbed by tissue, stimulating light for optogenetic control does not reach deep in the tissue irradiated from ...

Soft gamma-ray constraints on a bright flare from the Galactic Center supermassive black hole

open access: yes, 2009
Sagittarius A* (Sgr A*) is the supermassive black hole residing at the center of the Milky Way. It has been the main target of an extensive multiwavelength campaign we carried out in April 2007.

The Cosmic Infrared Background: Measurements and Implications [PDF]

open access: yes, 2001
The cosmic infrared background records much of the radiant energy released by processes of structure formation that have occurred since the decoupling of matter and radiation following the Big Bang.

An infrared flash contemporaneous with the γ-rays of GRB 041219a [PDF]

open access: yesNature, 2005
The explosion that results in a cosmic gamma-ray burst (GRB) is thought to produce emission from two physical processes: the central engine gives rise to the high-energy emission of the burst through internal shocking, and the subsequent interaction of the flow with the external environment produces long-wavelength afterglows.

Development and Validation of a One‐Dimensional Finite Difference Simulation Scheme for Polymer Laser Powder Bed Fusion with Application to the Effect of the Inter Layer Time

open access: yesAdvanced Engineering Materials, EarlyView.
The study presents an efficient simulation approach for the polymer laser powder bed fusion process polymers process, validated with polyamide 12, polyamide 6, and polyetherketoneketone. It shows that inter layer time affects part density, with 90s yielding dense parts.
