Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Vapor kinetic energy for the detection and understanding of atmospheric rivers

Nature Communications
Poleward water vapor transport in the midlatitudes mainly occurs in meandering filaments of intense water vapor transport, spanning thousands of kilometers long and hundreds of kilometers wide and moving eastward.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Latent Heat Fluxes over Complex Terrain from Airborne Water Vapour and Wind Lidars [PDF]

, 2009
Tropospheric profiles of water vapour and wind were measured with a differential absorption lidar (DIAL) and a heterodyne detection Doppler wind lidar collo-cated onboard the DLR Falcon research aircraft in the past two years.

Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

Advanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

Advanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

Advanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge
