Structured Multilayer Thin Films for Catalytic Applications: A Novel Approach on Catalyst Design Utilizing Microfabrication Techniques

Advanced Functional Materials, EarlyView.
A structured multilayer catalyst is fabricated by combining RF magnetron sputtering and picosecond laser scribing to expose Cu–ZnO interfaces. This model catalyst, developed as a proof of concept, enables precise interface accessibility for CO2 hydrogenation to methanol.

Counting microstates of out-of-equilibrium black hole fluctuations

Journal of High Energy Physics
We construct and count the microstates of out-of-equilibrium eternal AdS black holes in which a shell carrying an order one fraction of the black hole mass is emitted from the past horizon and re-absorbed at the future horizon.
