Operando Observation of (Bi)carbonate Precipitation during Electrochemical CO2 Reduction in Strongly Acidic Electrolytes

Corsin Battaglia, Nukorn Plainpan, Alessandro Senocrate

Precipitation of (bi)carbonate salts during the electrochemical CO2 reduction (CO2RR) has been identified as a major cause of degradation and one of the main challenges to be overcome before implementing this technology on the industrial scale. Recently, t ...

Experimental assessment of the hydro-mechanical behaviour of a shale caprock during CO2 injection

Lyesse Laloui, Alessio Ferrari, Eleni Stavropoulou, Alberto Minardi, Taeheon Kim

The presented experimental study focuses on the hydro-mechanical characterisation of a shale caprock (Opalinus Clay) in contact with carbon dioxide. The objective of this paper, consists in the evaluation of the material's sealing capacity in terms of entr ...

Palladium Catalysed Intramolecular Carbo-oxygenation of Propargylic Amines to Access 1,2-Amino Alcohols and alpha-Amino Ketones via in situ Tether Formation

Phillip Gulliver Dominic Greenwood

a-Amino ketones and 1,2-amino alcohols are important structural motifs in organic chemistry, that can be observed in natural products, pharmaceutically and bioactive compounds. For these reasons, they constitute privileged targets for the development of ne ...

The impact of calcite impurities in clays containing kaolinite on their reactivity in cement after calcination

Karen Scrivener, Franco Alberto Zunino Sommariva, Emmanuelle Boehm Courjault

The use of supplementary cementitious materials as a partial replacement for Portland cement is the most effective way to reduce the carbon footprint of the concrete industry. Raw clays containing kaolinite (kaolin) are promising substitute materials. In t ...

Benefits and drawbacks of applied direct currents for soil improvement via carbonate mineralization

Lyesse Laloui, Dimitrios Terzis, Patrick Gabriel Yihsiu-Ming Hicher

The study presented herein adopts a new vision of the processes involved in carbonate mineralization induced by MICP from an electrochemical and crystal growth perspective. More precisely a specific line of focus refers to the species involved in the bio-c ...

The Atomic-Level Structure of Cementitious Calcium Aluminate Silicate Hydrate

David Lyndon Emsley, Karen Scrivener, Paul Bowen, Pierrick Berruyer, Brennan James Walder, Pinelopi Moutzouri, Aslam Kunhi Mohamed, Jirawan Siramanont, Maya Nicole Harris, Mattia Negroni

Despite use of blended cements containing significant amounts of aluminum for over 30 years, the structural nature of aluminum in the main hydration product, calcium aluminate silicate hydrate (C-A-S-H), remains elusive. Using first-principles calculations ...

Palladium-Catalyzed Carboxy-Alkynylation of Propargylic Amines Using Carbonate Salts as Carbon Dioxide Source

Jérôme Waser, Phillip Gulliver Dominic Greenwood

A palladium-catalyzed multicomponent reaction of propargylic amines, alkynyl bromides and cesium hydrogen carbonate to access oxazolidinones is reported. In contrast to previous reports, only a slight excess of cesium hydrogen carbonate is used as a surrog ...

Transforming Phosphogypsum Waste into Products with Market Value

Vast amounts of phosphogypsum (PG) which is a by-product of phosphorous acid production from apatite rock using sulphuric acid, are deposited in large piles at many locations worldwide. PG materials are added at rates of the order of megatonnes (Mt) per an ...
