Operando X‐ray Spectroscopy Study of Pd and Pd–Au Laterally Condensed Catalysts during Selective Acetylene Hydrogenation: The Role of Carbon

Advanced Materials, EarlyView.
The selective hydrogenation of acetylene over laterally condensed Pd and Pd–Au catalysts (LCCs) was investigated using operando X‐ray absorption and photoelectron spectroscopy in combination with density functional theory. Pd‐LCCs were found to incorporate significantly more carbon into the metal lattice than Pd–Au LCCs, where the carbon uptake governs

Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

Advanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Ultrasonic characterization of microwave joined silicon carbide/silicon carbide [PDF]

, 1997
High frequency (50--150 MHz), ultrasonic immersion testing has been used to characterize the surface and interfacial joint conditions of microwave bonded, monolithic silicon carbide (SiC) materials. The high resolution ultrasonic C-scan images point to damage accumulation after thermal cycling.

Advancements in TLP Bonding for Power Electronics Die‐Attach Applications

Advanced Materials Technologies, EarlyView.
Transient Liquid Phase (TLP) bonding is gaining traction as a lead‐free die‐attach technology in power electronics packaging. This review examines the state of TLP bonding, its key elements, reliability aspects, and practical limitations. This review also highlights emerging trends, such as nanostructured interfaces, that may improve scalability of TLP
