The tardigrade Dsup protein enhances radioresistance in Drosophila melanogaster and acts as an unspecific repressor of transcription

iScience, 2023
Summary: The tardigrade-unique damage suppressor protein (Dsup) can protect DNA from ionizing radiation and reactive oxygen species (ROS). In this study, we generated Dsup-expressing lines of Drosophila melanogaster and demonstrated that Dsup increased ...

Interphase Surface Stability in Liquid-Liquid Membrane Contactors Based on Track-Etched Membranes

Membranes, 2021
A promising solution for the implementation of extraction processes is liquid–liquid membrane contactors. The transfer of the target component from one immiscible liquid to another is carried out inside membrane pores.

The Competition between 4-Nitrophenol Reduction and BH₄⁻ Hydrolysis on Metal Nanoparticle Catalysts

Molecules, 2023
Assessing competitive environmental catalytic reduction processes via NaBH4 is essential, as BH4− is both an energy carrier (as H2) and a reducing agent. A comprehensive catalytic study of the competition between the borohydride hydrolysis reaction (BHR,

Direct reactions for nuclear astrophysics [PDF]

EPJ Web of Conferences, 2023
The neutron activation technique is a well established method to measure neutron capture cross sections relevant for the s-process. The 7Li(p,n) reaction at Ep = 1912 keV is often used as a neutron source since the energy distribution of the emitted ...
