ChemElectroChem, EarlyView.The present study is dedicated to investigation of the performance of oxidized Ti2(Al/Sn)C system (211 MAX phases) as anode for lithium and sodium ion batteries. Their behavior has been rationalized as function of the tin content and as function of the MAX phase order, with detailed comparison with the 312 MAX phase analog series.

Gradient‐Free Measurements of Catalyst Plates Using a Berty Reactor
Chemie Ingenieur Technik, EarlyView.A proof‐of‐concept for the adaption of a μ‐Berty reactor for wash‐coated catalyst plates and films is presented on the example of methanol synthesis from CO2. Such a configuration can be used to derive the kinetic parameters and optimize wash‐coat properties under very controlled and idealized conditions before translating them to microchannel or ...

Doubly robust criterion for causal inference
Canadian Journal of Statistics, EarlyView.Abstract In causal inference, semiparametric estimation using propensity scores has rapidly developed in various directions. At the same time, although model selection is indispensable in statistical analysis, an information criterion for selecting the regression structure between the potential outcome and explanatory variables has not been well ...

Analytical Study of Lanolin as Potential Biomarker of Prehistoric Sheep‐Shearing Practice
Chemistry–Methods, EarlyView.Lanolin, a complex wax found on sheep wool, accumulates on shearing tools, such as flint and obsidian blades, used since the Neolithic. This study explores lanolin's degradation patterns as a potential biomarker for prehistoric sheep‐shearing practices, employing micro‐Fourier transformed infrared spectroscopy, hyperspectral imaging, and gas ...
