Rutin in buckwheat grain meal determined by UV photoacoustic spectroscopy and HPLC

Nova Biotechnologica et Chimica, 2017
A relatively novel approach for easy and quick determination of rutin in buckwheat grain is suggested. The rutin content of the grain in seven common buckwheat (Fagopyrum esculentum) and six Tartary buckwheat (Fagopyrum tataricum) varieties was ...

Global trend analysis of the MODIS drought severity index [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2015
Recently, Mu et al. (2013) compiled an open access database of a remotely sensed global drought severity index (DSI) based on MODIS (Moderate Resolution Imaging Spectroradiometer) satellite measurements covering a continuous period of 12 years.

Synergistic Probe Combining Lysosome Anchoring and Tumor Defense System Targeting for Precise Tumor Visualization

Advanced Science, EarlyView.
A new generation of high‐precision fluorescent probes based on the lysosomal characteristics in tumor metabolic reprogramming and overexpressed tumor markers. The probe (CN‐D‐GGT) selectively label cancer cells in co‐culture systems and distinguish tumor lesions from inflamedand normal tissues in vivo, enabling precise tumor imaging.

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Folded-optics-based quartz-enhanced photoacoustic and photothermal hybrid spectroscopy

Photoacoustics
Folded-optics-based quartz-enhanced photoacoustic and photothermal hybrid spectroscopy (FO-QEPA-PTS) is reported for the first time. In FO-QEPA-PTS, the detection of the photoacoustic and photothermal hybrid signal is achieved through the use of a custom

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...
