MRI for Mixing Quality in Microfluidics

Magnetic Resonance in Chemistry, EarlyView.
Fluidic mixing in a micromixer: Paramagnetic relaxation enhancement and chemical shift differences were explored to reveal mixing quality at the small dimensions of an optically opaque y‐mixer. ABSTRACT Liquid state processes often involve mixing of process streams.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Stress‐guided photo‐programming of cholesteric liquid crystal elastomers for 2D‐to‐3D shape–color information encoding

Responsive Materials, EarlyView.
We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Critical point drying of brain tissue for X‐ray phase‐contrast imaging

Journal of Synchrotron Radiation, EarlyView.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.
