Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

Advanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Study of characteristics of the supraglacial runoff of the Austre Grønfjordbreen, Spitsbergen

Лëд и снег, 2023
Surface runoff on the glacier is represented by two aquifers: a hydro-network of streams and a porous layer of melting crust in which meltwater moves. The first one transfers water from the snowmelt zone, and the second one drains the ablation area. Data
