Epoxidation of Cashmeran and Unprecedented Rearrangement to an α‐Carbonyl δ‐Spirolactone

European Journal of Organic Chemistry, EarlyView.
A new strategy enables diastereoselective conversion of Cashmeran into a previously unknown α‐carbonyl δ‐spirolactone via epoxidation, Baeyer–Villiger oxidation, and acid‐catalyzed rearrangement. Structure and mechanism were confirmed by NMR, single crystal X‐ray diffraction, and computational studies. We report the epoxidation of Cashmeran followed by

A new technique for infrared scintillation measurements [PDF]

, 2017
We propose a new technique to measure the infrared scintillation light yield of rare earth doped crystals by comparing it to near UV–visible scintillation of a calibrated Pr:(Lu0.75Y0.25)3Al5O12 sample.

Body‐integrated photonic biosensors: Illuminating the path to active healthcare

FlexMat, EarlyView.
Body‐integrated photonic biosensors are promising tools for active healthcare. These optical devices can be worn, implanted, or swallowed to monitor health signals continuously. This review introduces key sensing modalities, including fluorescence, colorimetry, SPR, LSPR, SERS, and light‐modulating materials.

The Non‐Professional Virtues of the Hospice Volunteer

Journal of Applied Philosophy, EarlyView.
ABSTRACT Volunteers have long played a significant role in hospice care. Much of the care volunteers provide consists of weekly hour‐long in‐home visits. Home‐visiting hospice volunteers are not professionals, nor are they strangers or intimates. Hospice volunteers will not typically face moral dilemmas, nor be called upon to make dramatic decisions ...
