Nature‐Inspired Sustainable Cooling for Photovoltaics with Enhanced Temperature‐Salinity Dynamics

Advanced Functional Materials, EarlyView.
Addressing solar panel overheating, a nature‐inspired cooling system mimicking ocean currents is developed. A moisture‐absorbing solution layer uses sunlight, radiative cooling, and moisture processes to create temperature/salinity gradients, accelerating circulation. The prototype cools panels by up to 18.2 °C under sunlight, sustains cooling, rapidly

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

Advanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Determination of Dieldrin and Polychlorinated Biphenyls in Seawater by Solid Phase Extraction and Capillary Gas Chromatography

Yankuang ceshi, 2014
Dieldrin and polychlorinated biphenyls (PCBs) are toxic, organic pollutants that break down extremely slowly in the marine environment. Therefore, it is of valuable significance to establish a rapid, sensitive and accurate detection method for dieldrin ...

Dual‐Phased Molybdenum Carbides Confined in MOF‐Derived Carbon Nanoframes Enhance Capacitive Desalination

Advanced Functional Materials, EarlyView.
Dual‐phase MoC/Mo2C/CoNC nanoframes are synthesized via a MOF‐on‐MOF strategy, demonstrating a large salt adsorption capacity, a low energy consumption, and an excellent cycling stability. In situ/ex situ characterizations and DFT calculations reveal that the MoC/Mo2C dual phase transition facilitates Na+ adsorption/desorption, while interface‐induced ...
