Enhancing Hydrogen Storage in Carbon‐Substituted Beryllium Nitride: A DFT‐Based Investigation

Energy Storage, Volume 8, Issue 4, June 2026.
Carbon‐substituted BeN4 monolayers enable efficient hydrogen storage, achieving 6.02 wt% uptake with moderate adsorption energy (−0.24 eV) and near‐ambient desorption temperature (308 K). These results highlight BeN4 as a promising candidate for practical hydrogen storage applications.

RNAs Associated With Bacterial Outer Membrane Vesicles: Structural Insights Into Surface Composition

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
This work uncovers a new layer of bacterial communication. We show that RNAs, aided by the Hfq RNA‐chaperone, are not only packed inside Gram negative Outer Membrane Vesicles (OMVs) but can also be embedded in their membranes. This suggests that bacteria may use surface‐exposed RNAs to directly interact with host cells. Overall, our results broaden the

Nano‐Raman Spectroscopy of Tellurium Nanowires

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 1034-1039, June 2026.
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 1015-1024, June 2026.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).
