Finite Element Modeling of the Transition Zone between Aggregat and Mortar in Concrete [PDF]
, 2012 Visual observations to the Interfacial Transition Zone (ITZ) between aggregate and mortar in concrete showed that this area differs significantly to the bulk mortar, further away from the ITZ.

Aziridination of a Single Carbon Atom in Alkenes via Energy Transfer Catalysis
Angewandte Chemie International Edition, EarlyView.Contrary to traditional alkene aziridination via (formal) nitrene transfer, we herein report a strategy that achieves intermolecular aziridination of a single alkene carbon atom and installs an additional group at the other. Enabled by metal‐free energy transfer (EnT) catalysis, alkenyl boronates and silanes are transformed into reactive intermediates ...

Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis
Animal Research and One Health, EarlyView.Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

British Educational Research Journal, EarlyView.Abstract This paper critically analyses how school readiness has been historically and discursively constructed in Early Childhood Education (ECE) policy in England over the past four decades. Using Bacchi's ‘What's the Problem Represented to be?’ framework and Foucauldian concepts of governmentality, the paper explores how school readiness has shifted
