From Charge Storage Rulebook Rewriting to Commercial Viability of Zinc‐Manganese Batteries

open access: yesAdvanced Science, EarlyView.
The Mn3O4 cathode undergoes a partially in situ phase transition to MnO2 during the initial charging process, forming a hybrid Mn3O4/MnO2 cathode. The Mn3O4 provides a robust supporting structure for MnO2 to enhance the cathode stability upon H+/Zn2+ co‐insertion/extraction.

Effect of Added Ni Nanoparticles on the Microstructure and Mechanical Properties of Sn58Bi/Cu Solder Joints under Thermal Shock Conditions

open access: yesAdvanced Electronic Materials, EarlyView.
This article concludes that the microstructure as well as grain coarsening is suppressed and the growth of IMC layer is promoted in Sn58Bi/Cu solder joints versus Sn58Bi‐0.6 Ni/Cu solder joints after 1200 thermal shock experiments, while the mechanical properties of the solder joints are improved.

Cracks in Concrete

open access: yes
Finding and properly segmenting cracks in images of concrete is a challenging task. Cracks are thin and rough and being air filled do yield a very weak contrast in 3D images obtained by computed tomography. Enhancing and segmenting dark lower-dimensional structures is already demanding.

Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

open access: yesAdvanced Energy Materials, Volume 15, Issue 28, July 22, 2025.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...
