Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution
Advanced Functional Materials, EarlyView.The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces
Advanced Functional Materials, EarlyView.The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...

, 2014 We provide clear-cut evidence for economically and statistically significant multivariate jumps (multi-jumps) occurring simultaneously in stock prices by using a novel nonparametric test based on smoothed estimators of integrated variances. Detecting multi-jumps in a panel of liquid stocks is more statistically powerful and economically informative ...
