Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes

open access: yesAdvanced Materials, EarlyView.
Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities

open access: yesAdvanced Materials, EarlyView.
A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

Optimal user charges and cost recovery for roads in developing countries [PDF]

open access: yes
The optimal charge for road use is equal to variable costs for road maintenance, together with the costs road users impose on other road users and on the rest of society.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Perspective on Aqueous Batteries: Historical Milestones and Modern Revival

open access: yesAdvanced Materials, EarlyView.
This review retraces the development of aqueous batteries from classical Zn‐MnO2 chemistry to modern Zn and Ni systems, correlating voltage, capacity, and electrolyte formulation with practical performance. By mapping historical success and failure onto current and future research directions, it identifies guiding principles that steer the design of ...

Assessing the Mechanism of NH3 Sensing in Flexible Carbon‐Nanotube‐Based Chemoresistive Sensors via In Situ Photoemission Spectroscopy

open access: yesAdvanced Materials Interfaces, EarlyView.
Flexible carbon nanotube chemoresistors detect NH3 through charge‐transfer interactions directly revealed by in situ synchrotron X‐ray photoelectron spectroscopy. Binding‐energy shifts of ≈1 eV correlate with resistance changes, demonstrating that intra‐CNT charge transfer between NH3 and CNTs is the dominant sensing mechanism.
