Biofouling is a common phenomenon caused by waterborne organisms such as bacteria, diatoms, mussels, barnacles, algae, etc., accumulating on the surfaces of engineering structures submerged under water. This leads to corrosion of such surfaces and decreases their moving efficiency.

Objective: Patient positioning during clinical practice can be challenging, and mispositioning leads to a change in CT number. CT number fluctuation was assessed in single-energy (SE) EID, dual-energy (DE) EID, and deep silicon photon-counting detector (PCD) CT over water-equivalent diameter (WED) with different mispositions.
Methods: A phantom containing five clinically relevant inserts (Mercury Phantom, Gammex) was scanned on a clinical EID CT and a deep silicon PCD CT prototype at vertical positions of 0, 4, 8, and 12 cm.
Architecture of a novel NIR and switch-on fluorescent chemosensor based on mercapto propanehydrazide-functionalized chromenylium-cyanine for the quantification of mercury(II) in environment and living cells.

A novel probe NIR8 decorated with colorimetric, fluorometric, turn-on, and NIR properties was designed and synthesized using the chromenylium-cyanine platform for sensitive and selective quantification of Hg in real samples. The interaction between the probe and Hg resulted in the opening of the closed spirolactam ring of the chromenylium-cyanine platform, leading to a notable color shift from yellow to green. Concurrently, ratiometric spectral changes at 380 and 725 nm for UV-Vis and signal enhancement at 755 nm for fluorescence were observed.

This study assesses differences between BP values measured by both devices in children and youth aged 6 to 17 years and whether equations could be developed to compare BP measurements taken using the two devices.
Data And Methods: In Cycle 6 (2018 to 2019) of the CHMS, BP was measured using BT and OM devices.
Sensitive Detection of Hg and l-Cysteine through Optical Asymmetry-Tuned Fluorescence Switch Off-On Behavior in N-Doped Chiral Carbon Dot.

Blue-emissive nitrogen-doped chiral carbon dots (d-NCD230 and l-NCD230) exhibiting antipodal chiroptical activity, synthesized from the thermal pyrolysis of citric acid and d/l-aspartic acid in 1:2 molar ratios, have been explored as chirality-based fluorescent turn-off/on probes for the detection of Hg and l-cysteine (l-Cys). Circular dichroism (CD) spectroscopy revealed that the chiroptical activity originates from a synergy among intrinsic chirality, chiral precursors on the NCD surface, and hybridization of lower energy levels within the embedded chiral chromophore. Quantitative analysis of optical asymmetry using the Kuhn asymmetry factor () at the CD signal of 312 nm showed a higher value for d-NCD230 (1.
