Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”

open access: yesGeophysical Monograph Series, Page 449-486., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Écoles lancastériennes, citoyenneté républicaine et imagination spatiale en Amérique au début du xixe siècle [PDF]

open access: yes, 2010
La pédagogie de Joseph Lancaster fut adoptée par la plupart des écoles publiques américaines en milieu urbain au début du xixe siècle. Le système de Lancaster utilisait une seule salle de classe, énorme, pour l’instruction de centaines d’enfants pauvres ...

Controlling Exsolution Dynamics in High‐Entropy Oxides for Highly Active and Selective Acetylene Semi‐Hydrogenation

open access: yesAngewandte Chemie, EarlyView.
Li+‐induced lattice distortion, valence variation, and local charge redistribution in a rock salt‐structured high‐entropy oxide enable controlled metal exsolution, altering the Cu–Ni–Co exsolution sequence and delivering a surface Cu0‐enriched catalyst with exceptional activity and ethylene selectivity for acetylene semi‐hydrogenation.

Planning the American Neighborhood: The Science of Sociability at the Dawning of Desegregation (1933-1965) [PDF]

open access: yes, 2020
Segregated housing became a subject for scientific inquiry between the New Deal and Civil Rights eras. In this dissertation, I trace studies of segregated housing to the planned communities that the federal government set in motion by building public ...

Deciphering the Dynamic Balance Between Solvation Strength and Polysulfides Reaction Heterogeneity in Practical Lithium‐Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A weakly solvating fluorinated cosolvent (1200ET) enables precise solvation‐power regulation in Li–S batteries, decoupling interfacial stabilization from sulfur redox kinetics. This approach suppresses polysulfide dissolution while preserving reaction kinetics, leading to a stable Li metal interface and high‐energy multilayer pouch cells, revealing a ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

open access: yesAdvanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

open access: yesAdvanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Autonomous X‐Ray Fluorescence Mapping for Nanoscale Chemical Speciation of Fine Particulate Matter

open access: yesAdvanced Intelligent Discovery, EarlyView.
We present X‐AutoMap, an autonomous X‐ray fluorescence mapping framework that integrates real‐time analysis with rule‐based computer vision to selectively target chemically relevant regions. By avoiding background‐dominated areas, the method reduces acquisition time by fourfold while enabling accurate particle‐level speciation.

Treatment Priorities in Patients With a History of Laryngeal Cancer: A Conjoint Analysis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To investigate patient priorities that may inform the choice of laryngeal cancer treatment. Study Design Multi‐institutional, survey‐based, conjoint analysis study focusing on seven attributes: lifespan, treatment type, cancer cure, self‐image, mode of breathing, voicing, and swallowing.
