2D Ruddlesden‐Popper phase perovskite (RPP) films for applications in photovoltaics are shown to exhibit structural heterogeneities at both microscopic and mesoscopic scales that can affect cross‐film charge carrier transport. The mechanisms of RPP film formation and the possible means to control film structure to optimize 2D perovskite solar cell ...

This study introduces the concept of ‘hybrid promoters (HP),’ which refers to specific combinations of two thermodynamic promoters (P1 and P2) that synergistically enhance the stability of gas hydrates. Abstract Natural gas still constitutes a substantial portion of global energy demand, necessitating the development of more sustainable, economical ...

The Role of Dynamic Solvent Swelling in Electrochemical Doping of Semiconducting Polymers
Solvent swelling in organic electrolytes dynamically evolves during electrochemical doping of poly(3‐hexylthiophene) (P3HT); multiple polymers, ranging from highly regioregular to fully regiorandom, demonstrate how crystallinity controls swelling.

Surface Properties of p‐GaN and Formation of Nickel Metal Contacts
The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...

Improved ORR Performance of Precious Metal‐Free Fe Single‐Atom Catalysts by Heteroatom Doping
In this study, a Fe single‐atom catalyst doped with heteroatoms is synthesized, and it is demonstrated that the doping strategy significantly improves both the catalytic activity and the stability of the material. Advanced characterization techniques, including AC‐STEM and XAS, are employed to confirm that the Fe atoms are present in a well‐dispersed ...
