Multichannel Photoluminescence of Graphene Quantum Dots Across Femtosecond to Cryogenic Timescales

Small, EarlyView.
This study reveals how graphene quantum dots emit light across all relevant timescales, from femtoseconds to cryogenic steady states. By integrating optical Kerr gating, time‐correlated single‐photon counting, and low‐temperature photoluminescence, distinct intrinsic, surface, and defect‐related emission channels are temporally and spectrally ...

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

VIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Novel Histopathologic Features of Diffuse Blue‐Gray Hyperpigmentation Associated With Kratom Use: A Case Report and Literature Review

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Drug‐induced hyperpigmentation accounts for 10%–20% of acquired pigmentary disorders and can be misdiagnosed for other causes such as melasma, post inflammatory changes, or heavy metal deposition. Kratom (Mitragyna speciosa), a Southeast Asian plant with an opioid‐like profile, has been increasingly used in the United States for ...
