CO2 uptake potential due to concrete carbonation: A case study

Case Studies in Construction Materials, 2017
The cement manufacturing process accounts for about 5% CO2 (carbon dioxide) released into the atmosphere. However, during its life cycle, concrete may capture CO2 through carbonation, in order to, partially, offset the impact of its production.

Broad Skills, Smaller Footprints? Generalist CEOs and Firm Biodiversity Exposure

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine whether CEO generalist skills predict firm‐level biodiversity risk exposure, an emerging strategic and financial concern. Using the biodiversity indicator developed based on textual analysis and the General Ability Index, we find that firms led by generalist CEOs are associated with significantly lower disclosed biodiversity risk ...

Theoretical Framework for Predicting Dynamic Covalent Exchange Based on Proton Affinities and Proton‐Transfer Assistance

Chemistry – A European Journal, EarlyView.
Proton‑transfer catalysis controls acylsemicarbazide dissociation, linking proton affinity to exchange kinetics and enabling predictive design of robust, tunable dynamic covalent networks. ABSTRACT We provide design principles for predicting bond exchange kinetics in acylsemicarbazide (ASC)‐based systems that can be applied to tuning the properties of ...
