High‐Speed Slot‐Die Coating with Donor‐Priority Rapid Aggregation Kinetics for Improved Morphology and Efficiency in Ecofriendly Organic Solar Cells

Advanced Science, EarlyView.
A donor‐priority rapid aggregation strategy is developed to efficiently improve the film‐forming kinetics as well as film morphology. The resultant slot‐die coated ecofriendly organic solar cells exhibit high power conversion efficiency of 17.4% at ultrahigh coating speed of 500 mm s−1, without the need for additives or complex post‐treatment ...

Dynamic Molecular Cocrystals with Alkyl Chain Dependent Thermosalient Phase Transitions

Advanced Science, EarlyView.
A series of cocrystals containing 5‐fluorocytosine and fatty acids with varying alkyl chain lengths are synthesized, demonstrating a systematic modulation of thermosalient phase transition temperatures across a broad range (≈100 K). This study reveals a linear correlation between interlayer hydrophobic interactions and transition temperatures, offering

Resonant Spin Amplification and Accumulation in MAPbI3 Single Crystals

Advanced Science, EarlyView.
Carrier spin dynamics are studied in a 20 µm thin MAPbI3 perovskite single crystal using time‐resolved Kerr ellipticity at cryogenic temperatures. Long spin relaxation (30 ns) and dephasing (21 ns) enable spin accumulation. Spin accumulation effects are discussed in detail along with carrier‐nuclear spin interactions.

A Sub‐Diffraction‐Limit Dimension All‐Plasmonic Optical Memory Using Non‐Linear Photochromism

Advanced Science, EarlyView.
An all‐plasmonic optical memory is demonstrated by using nonlinear plasmonics on a sub‐diffraction limit plasmonic nanowire waveguide coated with a photochromic diarylethene that supports the complete memory processes, “Write”, “Erase”, and “Readout” the memory ON/OFF states. Abstract The development of compact, high‐speed, and energy‐efficient optical

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

Advanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and
