State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

Self-protection of individual CD4+ T cells against R5 HIV-1 infection by the synthesis of anti-viral CCR5 ligands. [PDF]

open access: yesPLoS ONE, 2008
It is well established that paracrine secretion of anti-viral CCR5 ligands by CD8+ and CD4+ T cells can block the infection of activated CD4+ T cells by R5 and dual-tropic isolates of HIV-1.

Hydrogen Atom Transfer: An Intramolecular Main‐Group Metal‐Ligand Cooperative Biradical Pathway

open access: yesChinese Journal of Chemistry, EarlyView.
The molecular system consisting of a main‐group metal and a redox‐active ligand, ((2,6‐iPr2C6H3)NC(Me))2AlCl(THF), has been shown to react with azides and diazomethanes, yielding products through both a biradical intermediate and a hydrogen atom transfer process.

Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...
