Lactiplantibacillus Plantarum GUANKE Alleviates Allergic Asthma by Restricting Monocyte‐to‐DC Differentiation Via Microbiota‐Associated IAA

open access: yesAdvanced Science, EarlyView.
Lactiplantibacillus plantarum GUANKE remodels the indigenous gut microbiota and is associated with microbiota‐dependent restoration of circulating IAA. IAA treatment attenuates JAK3‐STAT3 and Jag1‐Notch4‐Hey1 signaling and reduces CX3CR1+Ly6C− monocytic precursor generation and pulmonary CD11b+ DC accumulation, together with reduced Th2 inflammation ...

Coevolution of minerals in lacustrine mudstone during diagenesis: a case study of the dongying depression in the Bohai Bay Basin

open access: yesFrontiers in Earth Science
In sedimentary basins, the lithologic characteristics of mudstone in different lithofacies differ, which is caused by the different types of diagenesis after sedimentation.

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

open access: yesAdvanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Bidirectional Disulfide Metathesis Enables Recycling of High‐Performance Thermoset Networks

open access: yesAdvanced Science, EarlyView.
A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

NiH‐Catalyzed Enantio‐ and Regioselective Hydroselenylation of Unactivated Alkenes

open access: yesAdvanced Science, EarlyView.
Nickel‐hydride‐catalyzed enantio‐ and regioselective hydroselenylation of unactivated alkenes provides access to chiral organoselenium compounds. Enantiodetermining Ni–H insertion followed by single‐electron diselenide activation generates selenyl radical.
