Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

open access: yesChemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Assessing the Effect of Large Igneous Provinces on Global Oceanic Redox Conditions Using Non‐traditional Metal Isotopes (Molybdenum, Uranium, Thallium)

open access: yesGeophysical Monograph Series, Page 305-323., 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.

Innovations for Stakeholder Engagement in Water Governance: A Systematic Literature Review From a Sustainability Transition Perspective

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Sustainable and equitable governance of water resources is among the most pressing global challenges, emphasising the need for innovations towards transitions in the water sector. Innovations for stakeholder engagement can contribute to such transitions through public participation and cross‐sectoral collaboration.

Insolvency‐related foreign judgements in Nigeria: Contextualising English legal influence and comparative analysis of the UNCITRAL regime

open access: yesInternational Insolvency Review, EarlyView.
Abstract The United Nations Commission on International Trade Law (UNCITRAL) has produced the most robust international insolvency regime applicable to countries around the world. The Model Law on Cross‐Border Insolvency (1997) is widely accepted and already very popular among African countries.

Split-Stirling-cycle displacer linear-electric drive [PDF]

open access: yes, 1983
The retrofit of a 1/4-W split-Stirling cooler with a linear driven on the displacer was achieved and its performance characterized. The objective of this work was to demonstrate that a small linear motor could be designed to meet the existing envelope ...

Navigating ESG in the Artificial Intelligence Era: Evidence From AI Pilot Zones in China

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT Artificial intelligence is reshaping business models, but limited literature explores how ESG evolves in the AI era. This paper regards AI Pilot Zones in China as a quasi‐natural experiment, and adopts the DID approach to investigate its impact on corporate ESG performance. Using the sample of Chinese A‐share listed companies from 2016 to 2022,
