Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy

open access: yesJournal of Polymer Science, EarlyView.
A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, EarlyView.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Targeted herbicide spraying systems: role of nozzle type, number of nozzle activation, nozzle orientation, and boom height on spray coverage and weed control

open access: yesPest Management Science, EarlyView.
Targeted herbicide application technology performance depends on sprayer configuration. Across five studies, activation of multiple, overlapping nozzles and maintaining appropriate boom height consistently improved spray coverage and weed control, highlighting the importance of optimized sprayer setup for effective and reliable weed control.

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

open access: yesSmall, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
