Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.

Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

Improved single‐layer powder core inductor design procedure for DC‐DC converters
One of the early design decisions for DC‐DC converters is the choice of an appropriate magnetic core material. Powder cores in particular are suitable due to their saturation flux density of up to 1.5 T.
