Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.

Photocarboxylation of Arylated 2H‐Azirines Exploiting Continuous Flow Technology

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient continuous process for the synthesis of trisubstituted oxazoles is reported which links the photochemical opening of azirines and the subsequent trapping of the azomethine ylides with CO2 gas. This highlights challenges and solutions when incorporating CO2 as a feedstock material for the photochemical synthesis of small heterocyclic ...

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Distinct latitudinal community patterns of Arctic marine vertebrates along the East Greenlandic coast detected by environmental DNA

open access: yesDiversity and Distributions, Volume 29, Issue 2, Page 316-334, February 2023., 2023
Abstract Aim Greenland is one of the places on Earth where the effects of climate change are most evident. The retreat of sea ice has made East Greenland more accessible for longer periods during the year. East Greenland fjords have been notoriously difficult to study due to their remoteness, dense sea ice conditions and lack of infrastructure.
