Image‐based and biochemical multimodal phenotyping for explainable classification of chia (Salvia hispanica L.) genotypes

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study developed an explainable machine learning framework integrating morphological, color, and biochemical characteristics for classifying chia (Salvia hispanica L.) genotypes. A dataset was assembled from 1200 seed images spanning four genotypes, from which 17 morphological and color features were extracted.

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Digital Printing of Photoreversible Protective Films

open access: yesMacromolecular Rapid Communications, EarlyView.
A photopolymerized and photoreversible temporary protective film based on an ortho‐nitrobenzyl crosslinker is presented that can be applied using aerosol jet printing. To improve adhesion to industry‐relevant surfaces, a polyethyleneimine‐based adhesion promoter was added to the aqueous formulation of diacrylate cross‐linker and acrylated macromers ...

Optimal Experimental Design for Fast and Accurate Relaxation Time Measurements in Magnetic Resonance

open access: yesMagnetic Resonance in Chemistry, EarlyView.
We apply D‐optimal experimental design to relaxation constant estimation in NMR relaxometry. The resulting sampling schedules concentrate measurements where the signal is most sensitive to the relaxation constant. Compared with conventional linear or logarithmic spacing, D‐optimal designs achieve better estimation accuracy and precision with fewer ...
