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 ...

Superconducting Lithium Hydride in a Chemical Capacitor Setup: A Theoretical Study
ChemPhysChem, EarlyView.Metallization of bulk lithium hydride has never been achieved through pressure alone. Single‐layer lithium hydride sandwiched between two support layers may resist hole doping up to substantial levels, forming a two‐dimensional metal (Fermi surface shown).

Image convolution using a probabilistic mapper on USB-AER board [PDF]
, 2008 In this demo we propose a method for computing real time convolution on AER images. For that we use signed events. The AER events produced on an AER retina or an image/video to AER conversor, are processed using a probabilistic multi event mapper ...

Technological Characterization of Cobalt and Nickel Ores from Greece for Metal Recovery
SeparationsGreece has mineral resources in which strategic elements such as nickel (Ni) and cobalt (Co) are present. In this study, characterizations of the metal concentrations of three laterite deposits, as well as minerals from a kiln originating from a mineral ...
