Ekonomika středověké těžby pomocí ohně či dláta : otázka energie
Archaeologia HistoricaPřed zavedením výbušnin v Evropě existovaly dva základní způsoby těžby: pomocí ohně a nástrojů, z nichž nejběžnější byly kladivo a dláto. Používání dřeva, a tedy i ohně, lze vysledovat až do protohistorických dob.

Phase-enabled metal-organic framework homojunction for highly selective CO2 photoreduction
Nature Communications, 2021 Homojunctions are very promising in photocatalysis, but challenging to achieve. Herein, authors report a well-defined hierarchical metal–organic framework-based homojunction, formed via a one-pot synthesis route directed by hollow transition metal ...

Exploring Curvature Effects in Direct‐Written 3D Curved Hollow Magnetic Nanoshells
Advanced Functional Materials, EarlyView.Fabricated by a hybrid FEBID/CVD method, 3D PtC/Co3Fe core–shell heterostructures with engineered curvature and shell thickness exhibit complex reversal modes with axially symmetric N'eel‐type domain walls. XMCD‐PEEM combined with full‐scale micromagnetic simulations reveal how curvature and thickness govern the domain wall energy landscape and shape ...

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Advanced Functional Materials, EarlyView.CuFeS2 is found to induce the formation of intermediate phases, highlighting a strong Cu–Fe synergistic effect during conversion reactions in lithium all‐solid‐state batteries (Li‐SSBs). The integrated reaction pathway effectively suppresses phase separation and accelerates reaction kinetics, leading to enhanced electrochemical reversibility and ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...
