Environmental differences associated with Eocene lithology formation in the Fushun Basin, northeast China: insights from sedimentary organic facies [PDF]

open access: yesOil Shale
The delineation of sedimentary organic facies is crucial for understanding the oil and gas generation in hydrocarbon source rocks. The Fushun Basin, characterized by abundant dark-colored sedimentary rocks rich in organic matter, serves as a prototypical

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 ...

Robust Photocatalytic Hydrogen Evolution Over a Conjugated Metal‐Organic Framework Heterojunction

open access: yesAdvanced Science, EarlyView.
We report a conjugated coordination polymer, Cd‐TMT (TMT = 1,3,5‐trimercaptotriazine), featuring an intrinsic molecular‐level charge transport network. The conjugated TMT ligands facilitate strong intra‐ligand charge transfer, while their ordered π‐π stacking along the [111] direction establishes a continuous pathway for directional electron migration,

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

open access: yesAdvanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

open access: yesAdvanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

The coal miner [PDF]

open access: yesNeurology, 2006
The following operations of Consolidation Coal will work the afternoon shift: the Arkwright Mine, the Osage Mine, the Humphrey Mine, the Pursglove Mine, the Blacksville Number 2 Mine. The message came crackling over the radio in Morgantown. It was broadcast every day, as routine as the notification of school closings after a snowstorm.

China's Low‐Carbon Energy Transition Over the Past Two Decades: Experiences and Implications

open access: yesAdvanced Science, EarlyView.
China's low‐carbon energy transition features a brief decline and subsequent rebound in coal consumption, alongside the rapid expansion of renewable energy. This study develops a stage‐based analytical framework to explain this evolution from the perspectives of economic development, energy security, and environmental sustainability, revealing how ...

The case for coal: India’s energy trilemma

open access: yes, 2015
The International Energy Agency (IEA) has estimated that 304 million people in India are without access to electricity. Unsurprisingly, in a speech earlier this year, Piyush Goyal, Minister of State for Power, Coal
