Atom–Cluster Synergy in Scalable Fe–Ru Dual‐Site Architectures Accelerates Alkaline Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

Lifts for emergency evacuation in apartment buildings [PDF]

open access: yes, 2008
A research project was undertaken to investigate whether the lifts can be used as an alternate emergency evacuation route in apartment buildings. The important parameters in relation to the issues were divided into three categories: human behavioural ...

Interface‐Mediated Catalysis for Improved Hydrogen Storage in Reactive Hydride Composites

open access: yesAdvanced Materials, EarlyView.
Catalyst–hydride interfaces are engineered in Co@C‐ and Ni@C‐modified 2LiH + MgB2 reactive hydride composites to accelerate hydrogen uptake and release. Multiscale scattering, in‐situ synchrotron radiation powder x‐ray diffraction and density functional theory calculations reveal the structural and electronic origin of the catalytic enhancement ...

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

open access: yesAdvanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...
