Three-dimensional core-collapse supernova simulated using a 15 $M_\odot$ progenitor

open access: yes, 2015
We have performed ab initio neutrino radiation hydrodynamics simulations in three and two spatial dimensions (3D and 2D) of core-collapse supernovae from the same 15 $M_\odot$ progenitor through 440 ms after core bounce.

Isolation and Reactivity of a Square‐Planar Trisamido Silane

open access: yesAngewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

open access: yesAngewandte Chemie International Edition, EarlyView.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

High Density Polyethylene/Ground Tire Rubber Composites Compatibilized by Dicumyl Peroxide

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT In this study, the thermal behavior of dicumyl peroxide (DCP) was first evaluated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which confirmed a peak decomposition temperature around 172°C, highlighting its incompatibility with standard melt‐mixing techniques for most polyolefins. To overcome this limitation,
