Precipitation (MICP) is a process used in geotechnical engineering and heritage preservation to improve the mechanical properties of low-cohesive soils and porous granular media, or to heal fractures that form in

extractive metallurgy techniques. Two main causes of low ore recovery rate in porous media via leaching are identified, i.e., passivation of mineral surfaces and heterogeneity of the flow field, which creates

, these methods remain restricted to specific polymers and low level of parallelization. Our transdisciplinary consortium of 3 laboratories (Ingénierie des Matériaux Polymères, Lyon; Laboratoire de Physique ENS de

is low compared to the ion cyclotron frequency. However, this low-frequency approximation does not apply to most experiments, where the phase velocity is of the same order of magnitude as the ion

multiple proton-coupled steps, resulting in low selectivity and competing reactions. So far, Cu-based materials are promising (electro- and thermo-)catalysts for CO2 reduction, however solar-driven

demonstrated ion trapping of single Yb+ ions. Optical clocks based on ultra-narrow transitions in trapped ions and neutral atoms have reached fractional uncertainties in the low 10-18 range, enabling landmark

paleo studies. Furthermore, our knowledge of Holocene climate at high altitudes remains very limited (Jomelli et al., 2022). Monsoon proxies located at low altitudes show no direct links with glacier

dedicated, low-energy electron beam ion trap (EBIT) optimized for the production of highly charged ions of light nuclei that remain beyond the reach of storage rings. This EBIT, a central element of the
