Detecting Cr6+ at ≈100 pM Concentration with Fluorescence Enhancement Signatures in a Novel Eco‐Fluorophore: Matching WHO's 96 pM Recommended Standard for Drinking Water

open access: yesAdvanced Materials, EarlyView.
Through a dual‐functionalization strategy, carbon quantum dots (CQD) with exceptional fluorescence properties are engineered. These CQD are integrated with graphitic carbon nitride to form a 2D/2D heterostructure via both covalent and non‐covalent modification.

Meteoritic Tutton salt, a naturally inspired reservoir of cometary and asteroidal ammonium [PDF]

open access: yesarXiv
The lack of benchmark data on the real minerals, native ammonium carriers in Solar System gives rise to controversial opinions on extraterrestrial ammonium reservoirs. We herein report on discovery of the first mineral carrier of meteoritic ammonium and show its relevance to the compositional and spectral characteristics of cometary and asteroidal ...

Robust Mix‐Charged Polyzwitterionic Hydrogels for Ultra‐Efficient Atmospheric Water Harvesting and Evaporative Cooling

open access: yesAdvanced Materials, EarlyView.
Conventional atmospheric water‐harvesting hydrogels prioritize hygroscopicity at the expense of mechanics, hindering its practical applications. The proposed hygroscopic mix‐charged polyzwitterionic hydrogel(THMPH) achieves a trade‐off between high water absorption and exceptional mechanical robustness through a strength gradient‐enhanced ionic cross ...

One‐Pot Single‐Step Approach for the Controlled Synthesis of Multifunctional Microparticles

open access: yesAdvanced Materials, EarlyView.
A versatile one‐pot strategy combines bipolar electrochemistry and the water‐organic interface to synthesize in a single‐step complex patchy particles, which cannot be achieved by any other deposition process. Under the influence of an electric field, microparticles undergo selective surface modification via coupled redox reactions, enabling ...
