Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, Volume 36, Issue 53, 2 July 2026.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Pholidota‐Inspired Electronic Skin Possessing Terahertz‐Wave Reflection–Absorption–Transmission Switchability

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
The pholidota‐inspired electronic skin is successfully constructed, originally realized four‐state reversible switching of terahertz‐wave reflection, absorption, transmission, and secondary reflection. In response to external demands, it issues deformation instructions, verifies the deformation state after the equipment executes the action, and thus ...

Hyperspectral wavelength selection for weed discrimination in Eucalyptus saligna using machine learning

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Efficient weed management in commercial forestry requires reliable methods for distinguishing crop seedlings from competing vegetation during early plantation establishment. This study aimed to identify spectral wavelength ranges suitable for discriminating weeds from Eucalyptus saligna in young forest plantations.

Detecting cotton Verticillium wilt within and across multiple fields with Sentinel‐2 imagery and machine learning

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Verticillium wilt, caused by Verticillium dahliae, poses a major threat to cotton production worldwide. This study presents a framework for predicting Verticillium wilt incidence across multiple cotton fields by combining Sentinel‐2 imagery, preseason inoculum, and weather variables with machine learning models.
