Article Synopsis
  • The study focuses on the hole-mediated oxidation reaction, a key step in photocatalytic water dissociation, using advanced time-resolved spectroscopy methods.
  • Researchers investigate the reaction at the surface of the TiO photocatalyst in contact with liquid water, revealing that water dissociation occurs within 20 picoseconds after UV light activation.
  • The findings show the conversion of water into Ti-OH groups and deprotonation occurs similarly at both acidic (pH 3) and basic (pH 11) conditions, providing insights for improving photocatalyst design.

Activity monitoring of living creatures based on the structural vibration of ambient objects is a promising method. For vibration measurement, multi-axial inertial measurement units (IMUs) offer a high sampling rate and a small size compared to geophones, but have higher intrinsic noise. This work proposes a sensing device that combines a single six-axis IMU with a beam structure to enable measurement of small vibrations.

This case report documents a rare and unique presentation of an oropharyngeal duplication cyst and subsequent neonatal airway management. A one-day-old premature female presented with postpartum respiratory distress requiring emergent intubation secondary to an oropharyngeal mass of the left tongue. After being stabilized and transferred to an academic center, imaging revealed a cystic lesion that was then marsupialized and drained by the otolaryngology team.

In this work, a novel method is presented for non-contact non-invasive physical activity monitoring, which utilizes a multi-axial inertial measurement unit (IMU) to measure activity-induced structural vibrations in multiple axes. The method is demonstrated in monitoring the activity of a mouse in a husbandry cage, where activity is classified as resting, stationary activity and locomotion. In this setup, the IMU is mounted in the center of the underside of the cage floor where vibrations are measured as accelerations and angular rates in the X-, Y- and Z-axis.
