Hazard from Himalayan glacier lake outburst floods
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Glacier lake outburst floods (GLOFs) have become emblematic of a changing mountain cryosphere. The Himalayas suffered the highest losses from these sudden pulses of meltwater but lack a quantitative appraisal of GLOF hazard.

Advanced Functional Materials, EarlyView.While host structures are known to enhance the reversibility and safety of lithium metal deposition, their additional volume and weight often decrease the battery's energy density and specific energy. By combining a lightweight and porous scaffold of electrospun polymer with a thinner separator, this article demonstrates a simultaneous improvement of ...

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings
Advanced Functional Materials, EarlyView.This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Meltwater Intrusions Reveal Mechanisms for Rapid Submarine Melt at a Tidewater Glacier [PDF]
, 2019 Submarine melting has been implicated as a driver of glacier retreat and sea level rise, but to date melting has been difficult to observe and quantify. As a result, melt rates have been estimated from parameterizations that are largely unconstrained by ...

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals
Advanced Functional Materials, EarlyView.A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Global warming accelerates uptake of atmospheric mercury in regions experiencing glacier retreat
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance In this study, we identify a process that recaptures atmospheric Hg in glacier-retreated areas driven by global warming. Melting of glaciers is known to release Hg originally locked in ice into the atmosphere and downstream ecosystems ...

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement
Advanced Functional Materials, EarlyView.An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...
