Thursday 9 November 2023 at the Istituto Lombardo – Accademia di Scienze e Lettere in Milan prof. Todeschini was invited to hold a conference on the scientific activity of his great-grandfather prof. Wilhelm Körner entitled “Wilhelm Körner: dalla molecola alla struttura molecolare”. Slides are available at this link.
Which is the effect of different types of molecular fingerprints for exploring the chemical space of natural products? Have a look here: https://doi.org/10.26434/chemrxiv-2023-0m355
Random Forest has been added as classification method in the latest release of the Classification toolbox for MATLAB. The toolbox is available for download at this link: https://michem.unimib.it/download/matlab-toolboxes/classification-toolbox-for-matlab/
We have published a comprehensive review on classification-based chemoemtric approaches to predict taste of molecules, have a look!

A new release of the Kohonen and CPANN toolbox (4.6) is now available. In this release, GPU and CPU calculation has been improved. The Kohonen and CPANN toolbox for MATLAB is a collection of MATLAB modules for training Kohonen Maps (Self Organising Maps, SOMs), Counterpropagation Artificial Neural networs (CPANNs), Supervised Kohonen networks (SKN), XY-fused networks (XY-F). It can be downloaded here: https://michem.unimib.it/download/matlab-toolboxes/kohonen-and-cpann-toolbox-for-matlab/

Membrane introduction mass spectrometry (MIMS) is a direct mass spectrometry technique used to monitor online chemical systems or quickly quantify trace levels of different groups of compounds in complex matrices without extensive sample preparation steps and chromatographic separation. Here a recent review:
