Nanosecond Hyperquenching for Electron Cryo‐Microscopy Without Air‐Water Interface Artifacts

open access: yesChemistry – A European Journal, EarlyView.
A novel method for the ultrafast vitrification of the biological assemblies is assayed by the electron cryotomography. Protein specimens prepared by this method inherently lack the spatial/structural artifacts, which derive from the surface tension at the air‐water interface (AWI).

Antibacterial and antiviral activity of a highly efficient electrospun r‐PET nanofiber

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Since the COVID‐19 pandemic, the emergence of clean air has increased interest in developing antimicrobial air filters, targeting sterilization and public health concerns. Nanofibers are a promising approach due to their high efficiency in air filtration, while nanoparticles adhered to the fibre surfaces can improve safety due to the biocidal ...

Fast Multidimensional Flow Nuclear Magnetic Resonance at High Field for Real‐Time Reaction Monitoring and Flow Synthesis

open access: yesChemistry–Methods, EarlyView.
Flow nuclear magnetic resonance (NMR) spectroscopy methods, in which the sample is circulated through the NMR detector, are powerful tools for the real‐time monitoring of batch reactions, and as an in‐line detector in‐flow synthesis. The required fast and flow compatible NMR methods and the used experimental setup are described showcasing monitoring ...

Capturing Electrochemically Galvanic Exchange Events between Silver and Gold in Nonequilibrium and Equilibrium Realms

open access: yesChemistry–Methods, EarlyView.
A new methodology is presented to study the kinetics of the galvanic replacement reaction between silver and gold, allowing, for the first time to our knowledge, real‐time monitoring of the dynamics of this redox reaction by quantifying the main driving force, that is, the time‐ and concentration‐dependent redox potential, which cannot be captured by ...
