Fixed‐Linkage Enabled Ultra‐Stable Ion Transport Channels in Membranes for Long‐Life Alkaline Flow Batteries

Advanced Science, EarlyView.
Rigid fixed‐ethylene‐linked PBI membrane stabilizes ion‐transport channels, enabling high ionic conductivity and durable alkaline Zn─Fe flow batteries. ABSTRACT Alkaline zinc–iron redox flow batteries (Zn─Fe FBs) are promising candidates for developing high‐voltage and cost‐effective grid‐scale energy storage systems.

Buried Unstrained Germanium Channels: A Lattice‐Matched Platform for Quantum Technology

Advanced Science, EarlyView.
ABSTRACT Strained germanium (ε$\varepsilon$‐Ge) and strained silicon (ε$\varepsilon$‐Si) buried quantum wells have enabled advanced spin‐qubit quantum processors. However, in the absence of suitable lattice‐matched substrates, ε$\varepsilon$‐Ge and ε$\varepsilon$‐Si are deposited on defective, metamorphic SiGe buffers, which may impact device ...

Gecko‐Like Multi‐Directional High‐Power Magneto–Mechano–Electric Energy Harvesters for Self‐Powered, Hundred‐Meter‐Scale LoRa Communication

Advanced Science, EarlyView.
Gecko like multi directional high power magneto mechano electric energy harvester (MME EH) for self powered, hundred meter scale LoRa communication. Inspired by the symmetric and flexible limb motion of geckos, the biomimetic harvester enables coordinated bending twisting responses to weak, low frequency (50/60 Hz) stray magnetic fields from power ...

Quantifying Strain and Its Effect on Charge Transport in Ge/Si Core/Shell Nanowires

Advanced Science, EarlyView.
This work demonstrates strain engineering in Ge/Si core–shell nanowires (CS NWs) by tuning the Ge core‐Si shell dimensions. Polarization‐resolved µ‐Raman and geometrical phase analysis quantify the resulting strain. Electronic transport measurements demonstrate record hole mobilities up to 25 400 cm2/Vs, highlighting these Ge/Si CS NWs as a promising ...
