Advanced Functional Materials, EarlyView.A cerium oxide‐carbon nanohybrid catalyst is synthesized via two distinct routes and is integrated into H‐type cells and gas diffusion layers (GDLs) to enhance electrochemical performance. Structural variations significantly affect performance, with the solvothermal sample exhibiting higher current densities.

Capacitated vertex covering [PDF]
Journal of Algorithms, 2003 Summary: In this paper we study the capacitated vertex cover problem, a generalization of the well-known vertex cover problem. Given a graph \(G=(V,E)\) with weights on the vertices, the goal is to cover all the edges by picking a cover of minimum weight from the vertices. When we pick a copy of a vertex, we pay the weight of the vertex and cover up to

Ultrahigh capacitive energy density in ion-bombarded relaxor ferroelectric films
Science, 2020 Defect-enhanced energy storage Dielectric capacitors are vital components of electronics and power systems. The thin-film materials of which capacitors are composed are usually optimized by changing the material composition. However, Kim et al.

Advanced Functional Materials, EarlyView.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Capacitative Calcium Entry [PDF]
Physiology, 1998 Capacitative Ca2+ entry is a recently discovered Ca2+ entry pathway that is activated on depletion of intracellular Ca2+ stores, providing an avenue for store refilling. Despite recent progress in elucidating the capacitative Ca2+ entry pathway, the mysteries of its molecular identity, its biophysical properties, and the store depletion signal remain.
