A High‐Performance and Fully Recyclable Supramolecular Nanofibrous Membrane for Multifunctional Air Filtration

Advanced Science, EarlyView.
A green, thermoreversible self‐assembly strategy yields a multifunctional and recyclable supramolecular nanofibrous membrane. Graphene oxide (GO) nanosheet acts as a heterogeneous nucleation‐templating agent, simultaneously modulating the supramolecular crystal packing while tailoring the nanofibrous architecture for elite performance.

Monitoring charged particles in indoor air using a neutral cluster and air ion spectrometer [PDF]

, 2012
While there are sources of ions both outdoors and indoors, ventilation systems can introduce as well as remove ions from the air. As a result, indoor ion concentrations are not directly related to air exchange rates in buildings.

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

Advanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Reinforcement of Cathode Interface Using a Dipolar Small Molecule for Enhancing Operational Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
We report a high‐dipole interlayer, MQPPO, that simultaneously improves efficiency and stability in perovskite solar cells. Its strong interfacial dipole enhances photovoltaic performance, while its uniform coverage and strong interaction with Ag effectively suppress AgI formation, ensuring long‐term stability under moisture and thermal stress.
