International migration and new mobility trends [PDF]

open access: yes
World migration community covers 3 per cent of the world population, in Europe it is around 7 per cent and 4 per cent in the Czech Republic. Europe is an important target for migration stimulated by the work offer but also by wars and natural disasters ...

Constructing Asymmetric Sn‐Cu‐C Interface via Defective Carbon Trapped Atomic Clusters for Efficient Neutral Nitrate Reduction

open access: yesAdvanced Materials, EarlyView.
This work constructs asymmetric Sn‐Cu‐C interface via anchoring SnCu atomic clusters on carbon defects. Such as‐synthesized SnCu‐DG catalyst achieves a high NH3 Faradaic efficiency (99.5%) and a record intrinsic activity of 2.61 × 10−17 mmol h−1 siteCu−1 at neutral electrolyte condition.

High‐Entropy Materials for Water Splitting: An Atomic Nanoengineering Approach to Sustainable Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...
