Long‐Term Cycling Stability of Sodium/Sodium Ion Cells Probed by In Situ Solid‐State NMR Spectroscopy

open access: yesBatteries &Supercaps, EarlyView.
The suitability of 23Na in situ solid‐state nuclear magnetic resonance (NMR) spectroscopy for long‐term studies of sodium/sodium ion cells is tested. Using silicon carbonitride and hard carbon working electrodes, local structures are analyzed up to the point of capacity degradation and cell failure.

Affinity Peptides With pH Sensitivity for the Enrichment of CD38+ Cells

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT The selective enrichment of cell populations based on surface markers is critical for the advancement of gene and cell therapies. Current antibody‐based cell isolation methods, such as fluorescence‐ and magnetic‐activated cell sorting (FACS and MACS), offer high specificity but are limited by scalability, cost, and potential adverse effects on

Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee

open access: yesChemie Ingenieur Technik, EarlyView.
Chlorogenic acid (CGA) concentration in coffee was predicted using mid‐infrared (MIR) spectroscopy and a machine learning approach. Forty‐four roasting stages (140–220 °C) plus a green coffee control were analyzed. A multilayer perceptron regressor, trained on preprocessed MIR data, outperformed traditional peak analysis, enabling accurate and ...
