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

open access: yesAdvanced 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

Can uncertainties in sea ice albedo reconcile patterns of data-model discord for the Pliocene and 20th/21st centuries? [PDF]

open access: yes, 2014
General Circulation Model simulations of the mid-Pliocene warm period (mPWP, 3.264 to 3.025 Myr ago) currently underestimate the level of warming that proxy data suggest existed at high latitudes, with discrepancies of up to 11°C for sea surface ...

Roll‐to‐Roll Processable EC/TC Hybrid Smart Windows Driven by a Bidirectional Dual‐Chromic Polymer Electrolyte

open access: yesAdvanced Functional Materials, EarlyView.
We present a scalable EC/TC hybrid smart window using a DCPE that enables tunable solar modulation (ΔTsol:15–43%), fast electrochromic switching (<90 s), and strong thermal blocking (10–14°C reduction). HPMC improves thermal stability, while an optimized ISL enhances EC performance.

Dual‐Layer Conducting and Redox Polymer Bioanodes for Synergistic Enhancement of Microbial Extracellular Electron Transfer

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid PEDOT/Fc‐LPEI conducting/redox polymer bioanode synergistically improves microbial extracellular electron transfer (EET) in Shewanella oneidensis MR‐1. The dual‐layer interface delivers 18‐fold higher current output and 27‐fold greater charge collected than bare carbon felt, highlighting an effective strategy for high‐performance ...

Bacterial Cellulose‐Based Bilayer Passive Cooler for High‐Performance Radiative/Evaporative Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A sustainable bilayer passive cooler based on bacterial cellulose integrates radiative and evaporative cooling for efficient zero‐energy temperature reduction. The scalable, low‐carbon material shows strong potential for food preservation, low‐temperature storage, and cold‐chain logistics.

New modeling of the Vostok ice flow line and implication for the glaciological chronology of the Vostok ice core [PDF]

open access: yes, 2004
We have used new spaceborne (elevation) and airborne (ice thickness) data to constrain a 2D1/2 model of snow accumulation and ice flow along the Ridge B-Vostok station ice flow line (East Antarctica).

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

open access: yesAdvanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.

Sky‐Directional Radiative Cooling Meta‐Films for Daylighting Windows

open access: yesAdvanced Functional Materials, EarlyView.
A geometry‐mediated microprism meta‐film enables transparent, sky‐directional radiative cooling for daylighting windows. By decoupling control of visible transmittance from mid‐infrared emissivity, ground‐emitted heat absorption is suppressed while skyward heat dissipation is enhanced.

Growth and motion at the Weddell Sea ice edge

open access: yes, 2007
The formation of sea ice in the presence of turbulence was studied using data from drifting buoydeployments and ice sampling in the Weddell Sea during April 2000.
