The first ground-state rotational spectrum of 3-methylstyrene (3MS) was measured by Fourier transform microwave spectroscopy under supersonic jet-cooled conditions. Transitions were assigned for two conformers: cis-3MS and trans-3MS. In the cis conformer, the vinyl group is oriented toward the methyl group, while in the trans conformer, it is positioned away from the methyl.

- Eschar and slough in wounds contribute to persistent inflammation and infection risks by harboring microorganisms, biofilms, and inflammatory substances.
- This study developed an in vitro model simulating wound conditions with artificial slough to test the effectiveness of a new antibacterial technology featuring silver-zinc EDTA complexes.
- Findings indicate that this new technology can effectively disrupt biofilms and may be beneficial in treating chronic wound infections.
This paper presents the use of principal component analysis (PCA) for time domain microphone array denoising to characterize an impulsive aeroacoustic source, which is illustrated with the aeroacoustic emission caused by a vortex ring/edge interaction. Prior studies have used signal processing approaches that required assumptions about the source directivity or user intervention at low signal-to-noise ratio (SNR) conditions. In this context, PCA, a matrix decomposition tool which identifies the most common features across an ensemble of observations, provides a data-driven (hands-off) approach to signal processing.

Whereas conventional potentiostats are ideal to develop assays in laboratory settings, they are in general, not well-suited for field work due to their size and power requirements. To address this need, a number of portable battery-operated potentiostats have been proposed over the years.

- Antimicrobial wound dressings are vital for preventing surgical site infections and chronic wound complications but require frequent changes to assess their effectiveness, which can hinder healing and increase costs.
- A new concept to monitor antimicrobial levels in dressings aims to ensure they remain effective without unnecessary changes, potentially improving clinical outcomes.
- The paper presents a patented electrochemical silver sensor that assesses silver ion levels in the presence of challenging conditions like serum and chloride, linking these measurements to the antimicrobial activity against harmful bacteria.
