Variational autoencoders for tissue heterogeneity exploration from (almost) no preprocessed mass spectrometry imaging data [PDF]
arXiv, 2017 The paper presents the application of Variational Autoencoders (VAE) for data dimensionality reduction and explorative analysis of mass spectrometry imaging data (MSI). The results confirm that VAEs are capable of detecting the patterns associated with the different tissue sub-types with performance than standard approaches.

Improving CO Oxidation Catalysis Over High Entropy Spinels by Increasing Disorder
Advanced Science, EarlyView.This work demonstrates that changing configurational disorder can significantly improve catalytic activity and stability. A series of high entropy spinel oxides (HESOs) are synthesized using air‐stable molecular precursors to build crystal lattices atom‐by‐atom. Spinel oxide powders are extensively characterized with a variety of advanced methods (i.e.
