Decoding Interfacial Polymerization Through Steady Amine Delivery and Real‐Time QCM‐D Monitoring

open access: yesAdvanced Science, EarlyView.
We combine steady amine delivery with in situ quartz crystal microbalance with dissipation to track interfacial polymerization in real time. The platform resolves three kinetic regimes: pre‐gelation oligomerization, post‐gelation aggregation and network growth, and diffusion‐limited film evolution.

Economical assessment of the High Speed Railway

open access: yesInternationales Verkehrswesen, 2016
Investing in High speed railways is a significant social decision. One of the major drawbacks is its high capital cost. However, the public decision makers should not only focus on the financial cost, but also the potential positive impacts on the society. A cost benefit analysis is a useful tool for economical assessment.

High‐Density‐Cluster Ru Catalyst Substitute for Pt/C Benchmark Improves Membrane Water Electrolysis

open access: yesAdvanced Science, EarlyView.
Yuan et al. report a high‐density, monodispersed Ru cluster catalyst featuring interfacial covalent bonds that modulate the electronic structure and optimize intermediate adsorption–desorption, thereby conferring pH‐universal HER activity with ampere‐level current densities and enabling the development of Pt‐free membrane electrodes.
