Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6

Advanced Science, EarlyView.
A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.

A Systemic Model for Understanding Business Interactions With Biodiversity and Ecosystems

Business Strategy and the Environment, EarlyView.
ABSTRACT Biodiversity loss and ecosystem degradation represent critical threats to human well‐being and economic resilience, challenging businesses to understand and manage their interdependence with natural systems. This study develops a systemic framework—the BioModel—that elucidates the reciprocal relationship between businesses, biodiversity, and ...

Three-dimensional shock-sulfur hexafluoride bubble interaction

AIP Advances, 2019
The evolution of shock-sulfur hexafluoride (SF6) bubble interaction is investigated using a detailed three-dimensional numerical simulation. The influences of the end wall distance on the bubble evolution are analyzed by using the high-resolution ...

Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

Beyond Carbon: Corporate Environmental Performance Across Multiple Domains

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine corporate environmental performance (CEP) as a multidimensional system rather than isolated outcomes. Combining institutional and behavioral perspectives, we analyze four domains—CO2 emissions, waste, energy, and water—using S&P 500 firms that disclosed data on all four domains (2006–2024).

Exploring the Interrelationships Among Supply Chain Emissions, Financial Performance, Market Value, and Board Sustainability: An Exploration of the European Landscape

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT National and supranational institutions are establishing emission trading systems and control schemes in an attempt to manage stakeholders' willingness to engage with regulatory systems and reduce greenhouse gas emissions (GHG). Nonetheless, despite the national and supranational focus on carbon neutrality, little research has been centered ...

Age of air from ACE-FTS measurements of sulfur hexafluoride [PDF]

Atmospheric Chemistry and Physics
Climate models predict that the Brewer–Dobson circulation (BDC) will accelerate due to tropospheric warming, leading to a redistribution of trace gases and, consequently, to a change of the radiative properties of the atmosphere.

Carbon emission assessment of tunnel infrastructures: From construction to operation

Deep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
