Black Plastic Identification for Sorting and Recycling With Deep‐UV Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present a deep ultraviolet (DUV) Raman spectrometer for sorting black plastics in recycling. The common identification modality of hyperspectral NIR struggles with black plastics due to strong absorption by the black pigment. By using a 248.6‐nm NeCu laser, we enable stand‐off detection over a conveyor belt while avoiding fluorescence interference ...

Circulating Tumor DNA as a Marker of Recurrence Risk in Stage III Colorectal Cancer: The α‐CORRECT Study

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Identification of colorectal cancer (CRC) patients at high risk of recurrence could be of substantial clinical use. We evaluated the association of ctDNA status, using a tumor‐informed assay, with recurrence‐free survival (RFS). Methods Stage III CRC patients were enrolled between 2016 and 2020.

On the fundamental additive modes of ocean color absorption

open access: yesLimnology and Oceanography, EarlyView.
Abstract Previous principal component analyses of ocean color absorption coefficient spectra aλ$$ a\left(\lambda \right) $$ have shown the variation in these data is captured by a few eigenfunctions. Here, we perform an unsupervised, non‐negative matrix factorization (NMF) of aλ$$ a\left(\lambda \right) $$ to derive their fundamental and physically ...

Temperature‐Dependent Spectroscopy and Laser Performance of Yellow Tb:YLF Lasers with 36% Slope Efficiency at Room Temperature and 61% at 100 K

open access: yesLaser &Photonics Reviews, EarlyView.
Highly efficient cryogenic yellow laser performance of Tb:YLF (Tb3+:LiYF4) is reported. The room temperature slope efficiency of 36% increases to 61% at 100 K, while the wavelength changes from 587 to 581 nm. Moreover, red laser emission at 624 nm with 47% slope efficiency at 78 K is demonstrated.

A Neuromorphic Camera for Tracking Passive and Active Matter with Lower Data Throughput

open access: yesLaser &Photonics Reviews, EarlyView.
The merits of an event‐based camera (EBC) for studies of passive and active matter are demonstrated. It is shown that it is possible to achieve results equivalent to those from an sCMOS camera while reducing data file sizes by up to two orders of magnitude.
