Improved Conductivity of Low‐Temperature‐Synthesized Graphene/Cu for CMOS Backend‐of‐Line Interconnect Applications

Advanced Materials Interfaces, Volume 12, Issue 5, March 3, 2025.
Laser pretreatment of copper foil significantly reduces surface roughness, improving smoothness by 37.39%, with the root mean square roughness decreasing from 22.2 to 13.9 nm. The AFM‐TUNA current image shows a 22‐fold increase in conductivity after laser treatment, highlighting better graphene quality and conductivity.

Mechanical and Morphological Perspectives on PLA‐Based Thermoplastic Vulcanizates (TPVs): A Brief Review

Macromolecular Materials and Engineering, Volume 310, Issue 2, February 2025.
This review highlights PLA‐based Thermoplastic Vulcanizates (TPVs) as promising materials that combine the processability of thermoplastics and elastomeric properties. Dynamic vulcanization of PLA‐based thermoplastic elastomers leads to new morphology such as sea‐sea or honeycomb structures.

Leistung und Stabilität eines Korund‐Typ‐In2O3‐Katalysators für die Kohlendioxidhydrierung zu Methanol

Angewandte Chemie, Volume 137, Issue 5, January 27, 2025.
Der rhomboedrische Polymorph des Indiumoxids zeigt im Vergleich zur kubischen Form eine bessere Leistung hinsichtlich Ausbeute, Selektivität und Stabilität bei der Hydrierung von Kohlendioxid zu Methanol. Die Stabilität des Katalysators und die Abfolge der Umwandlung von rhomboedrisch über kubisch zu metallischem Indium wird in situ mittels Synchrotron‐
