Short-period Variables in TESS Full-frame Image Light Curves Identified via Convolutional Neural Networks

The Astronomical Journal
The Transiting Exoplanet Survey Satellite (TESS) mission measured light from stars in ∼85% of the sky throughout its 2 yr primary mission, resulting in millions of TESS 30-minute-cadence light curves to analyze in the search for transiting exoplanets. To

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

Advanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

Leveraging Grain Boundary Effects for Nanostructured Electrode Layers in Symmetric Solid Oxide Fuel Cells

Advanced Materials Interfaces, EarlyView.
Nanocrystalline thin‐films of lanthanum chromite exhibit extraordinary properties of fast oxygen kinetics. These properties are due to the peculiar chemistry of grain boundaries and can be harnessed for fabricating symmetric electrochemical devices with self‐healing properties. Abstract While grain boundary engineering is attracting great interest as a
