  • As of yet, no clear structure–performance descriptors have been developed to tune the catalytic activity of zeolitic methanol-to-olefin catalysts. Now it has been shown that introducing Lewis acidity into Brønsted acidic zeolites boosts their performance. Although Brønsted acidity is found to define propylene selectivity, Lewis acidity is responsible for prolonging lifetime.

  • Mechanochemistry is a promising technology to tackle current and future polymer waste streams for a sustainable future. With this review, we take into account synthetic, computational, technical, and engineering perspectives to converge trituration and polymer mechanochemistry with a particular focus on the fate of commodity polymers and potential technologies to monitor mechanochemical reactions while they occur. We highlight the need for future transdisciplinary research to tackle the high-leverage parameters governing an eventually successful mechanochemical polymer degradation approach for a circular economy.

  • Haggenmüller et al. evaluate the performance of a smartphone app for non-invasive hemoglobin estimation that was developed in the USA in rural India. Performance improved when the app was retrained on the data collected in India.
