The conventional theories to predict the oxygen evolution reaction (OER) performance in electrochemical water-electrolysis, including the d-band center and the e orbital occupancy, encounter limitations under specific conditions. The d-band center serves as a partial descriptor of adsorption energy, leading to inconsistencies, and the e orbital occupancy theory underestimates the contributions of other orbitals. Here, a machine learning-assisted molecular orbital investigation is conducted to explore 3d orbitals characteristics.

Superfine recycled regenerated silk fibroin (RRSF) monofilament sutures are designed to minimize surgical incisions, prevent scar formation, and facilitate precise suturing in cosmetic and plastic surgeries. However, balancing fineness and strength remains a challenge because the RRSF extraction process disrupts the hierarchical structure of natural silk fibers, leading to suboptimal mechanical properties. This study employed mechanical peeling and grinding to exfoliate β-sheets-rich silk fibroin nanofibrils (SFNF), which served as homologous reinforcing materials uniformly dispersed in the RRSF spinning system.

Article Synopsis
  • The study investigated the use of face masks as tools for detecting exhaled substances, specifically acetaminophen, which could be captured on different layers of the mask due to their varying polarities.
  • Using a technique called thermal desorption-electrospray ionization tandem mass spectrometry (TD-ESI/MS/MS), researchers successfully identified acetaminophen signals concentrated around the mouth and nostril regions of the mask after ingestion.
  • The findings suggest that face masks offer a non-invasive method for drug monitoring, with implications for precision medicine by tracking drug use and effects over time.
