AI Article Synopsis
- The study confirms a theoretical prediction regarding the submersion of sodium clusters in helium nanodroplets, showing a transition from surface location to full immersion as cluster size increases.
- It identifies the specific electron energy threshold needed for ionizing larger Na(n) clusters, contributing to our understanding of their behavior in helium environments.
- The research establishes that a minimum cluster size of 21 atoms is necessary for full submersion, aligning with previous theoretical findings.
Article Abstract
The submersion of sodium clusters beyond a critical size in helium nanodroplets, which has recently been predicted on theoretical grounds, is demonstrated for the first time. Confirmation of a clear transition from a surface location, which occurs for alkali atoms and small clusters, to full immersion for larger clusters, is provided by identifying the threshold electron energy required to initiate Na(n) cluster ionization. On the basis of these measurements, a lower limit for the cluster size required for submersion, n ≥ 21, has been determined. This finding is consistent with the recent theoretical prediction.

Room-temperature sodium-sulfur (RT Na-S) batteries, known for their high-energy density, low cost and environmental friendliness, have attracted much attention. However, the development of RT Na-S batteries has encountered a number of challenges, including low conductivity and large volume changes of sulfur during the charge-discharge cycles. In this study, TiO nanoparticles modified porous carbon hosts for sulfur in RT Na-S batteries were prepared by a simple and efficient spray drying method combined with solution immersion.

Apatite nanoparticles are biocompatible nanomaterials, so their film formation on biodevices is expected to provide effective bonding with living organisms. However, the biodevice-apatite interfaces have not yet been elucidated because there is little experimental evaluation and discussion on the nanoscale interactions, as well as the apatite surface reactivities. Our group has demonstrated the biomolecular adsorption properties on a quartz crystal microbalance with dissipation (QCM-D) sensor coated with apatite nanoparticles, demonstrating the applicability of apatite nanoparticle films on devices.

Article Synopsis
- Specialized heat-sensitive neurons in the skin relay heat sensations, with the sodium-activated potassium channel Slick playing a significant role in controlling noxious heat responses.
- Researchers created mice lacking Slick in specific sensory neurons (SNS-Slick mice) and found these mice had quicker responses to painful heat tests compared to normal mice.
- Further experiments revealed that Slick works alongside the heat sensor TRPM3, suggesting that Slick helps to inhibit pain responses by modulating TRPM3 activity in sensory neurons.
