Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.

Fatigue Life Evaluation Using the Damage‐Equivalent Strain for 7075‐T6 Aluminum Alloy Under Bending and Torsion Bending Vibrations

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The vibrations caused by external factors (such as fluids) or internal factors often pose strength‐related problems in mechanical and structural components. Although several studies have investigated the material fatigue characteristics during vibration, reports on complex vibration modes such as torsion bending are limited.

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

Geostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Using confocal microscopy and image processing to measure properties of sub‐resolution cell structures: Application to cardiac transverse tubules

Journal of Microscopy, EarlyView.
Abstract Confocal microscopes increase the resolution of images by rejecting unwanted data from the out of focus regions of the specimen. This incurs a penalty in the recorded signal to noise ratio that may be partially ameliorated by inputting additional information during image processing.

The Origins of Ploem's Filter Cube: A Pandora's Box

Journal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.
