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 ...

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

A late Pleistocene human footprint from the Pilauco archaeological site, northern Patagonia, Chile.

open access: yesPLoS ONE, 2019
The present study describes the discovery of a singular sedimentary structure corresponding to an ichnite that was excavated at the paleo-archaeological site Pilauco (Osorno, Chile). The trace fossil is associated with megafauna bones, plant material and

Co‐Ligand‐Induced Electronic Modulation Controls Substrate Adsorption and Selectivity in Biomass Electrooxidation

open access: yesAdvanced Science, EarlyView.
A molecular design strategy is reported that introduces distinct anionic co‐ligands into Cu‐based catalysts to modulate the electronic density of the metal center and, consequently, its interaction with both OHads and HMF. The work establishes co‐ligand engineering as an effective strategy for precise interfacial adsorption control in electrocatalysis,

Nickelferrite on Pnictogen Functionalized Carbon Nanohorns. Bifunctional ORR and OER Catalysts in Rechargeable Zinc‐Air Batteries

open access: yesAdvanced Science, EarlyView.
A systematic study on the performance of N,P‐doped NiFe2O4@CNH bi‐functional hybrid electrocatalysts for rechargeable zinc‐air batteries is presented. The importance of P, N‐doping and the intimate tethering of nickel‐ferrite nanocubes on the carbon nano‐horn (CNH) surface which are well dispersed on the surface of N,P doped CNHs.

Reconstructing Miocene bird mating behavior from a fossil tracksite

open access: yesScientific Reports
Ichnofossils are important in paleoecological studies, interpreted as fossilized behaviors. Vertebrate footprints, a type of ichnofossils, can reveal the movements of trackmakers.

A Recyclable and Biodegradable High‐Performance Piezoelectric Nanogenerator for Self‐Powered Biosensing and Assistive Human‐Machine Interaction

open access: yesAdvanced Science, EarlyView.
By exploiting multiscale hydrogen‐bonding interactions between HFPD and TOCNF, the composite simultaneously achieves a high piezoelectric coefficient (14.0 pC·N−1), outstanding flexibility (100 000 bending cycles), water‐assisted recyclability, excellent biodegradability, and sensitive wearable/implantable sensing for motion, speech, and Morse code ...
