Miniature fuel cells relieve gas pressure in sealed batteries [PDF]

open access: yes, 1971
Miniature fuel cells within sealed silver zinc batteries consume evolved hydrogen and oxygen rapidly, preventing pressure rupturing. They do not significantly increase battery weight and they operate in all battery life phases.

Photoconductivity‐Driven Quantum Efficiency Gain in Inorganic Ruddlesden‐Popper Layered Cs2PbBr2I2 Perovskite Photodetector for Visible Light Detection

open access: yesAdvanced Functional Materials, EarlyView.
Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Chiral Nanohoops as an Efficient Spin Polarization System

open access: yesAdvanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...
