A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Decoding Viral Transmission Dynamics in Structured Populations Using a Microfluidic Herd‐Immunity‐on‐a‐Chip Platform

open access: yesAdvanced Science, EarlyView.
A microfluidic Herd‐Immunity‐on‐a‐Chip experimentally recreates structured contact networks to quantify viral transmission dynamics. By controlling susceptible, infected, and non‐susceptible populations, the platform reveals how contact topology governs the reproduction number, outbreak propagation, herd‐immunity–like behavior, and intervention ...

Autonomous Solar Metallurgy for High‐Purity Gold Recovery from Electronic Waste

open access: yesAdvanced Science, EarlyView.
Inspired by microbial strategies for metal uptake and biomineralization, defect‐rich copper sulfide (Cu31S16) functions as a solar metallurgical platform that unifies Au(III) capture, reduction, and self‐separation. The bioinspired design enables ultrafast gold recovery from electronic‐waste leachates and the spontaneous formation of millimeter‐scale ...

Urban Mobility and Transportation

open access: yes, 2019
Urban areas are developing quickly, innovative technologies grant enlarged scope for mobility management. According to literature, 50% of world population and as much as 75% of EU population live in cities, where the majority of GDP is generated. CO2 is responsible of 75% GHG worldwide and transportation is worth around 20% of this share and the ...

Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane

open access: yesAdvanced Science, EarlyView.
A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...
