Automated extraction of leaf mass per area from digitized herbarium specimens

open access: yesNew Phytologist, EarlyView.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Testing VIPV Curved Modules: Methods and Challenges

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 744-757, June 2026.
This work presents procedures and equipment for characterizing curved vehicle‐integrated photovoltaic (VIPV) modules through STC I–V curve and relative angular response (RAR) measurements. Outdoor measurements are compared with indoor measurements obtained using a collimated‐light solar simulator, showing excellent agreement for STC I–V curves.

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

The interplay between hydraulic capacitance and stomatal regulation strategy affects soil–plant hydraulics and transpiration

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2988-3000, June 2026.
Summary Plant water storage contributes to transpiration, but it is unclear how its relevance in supporting transpiration depends on the stringency of stomatal regulation. Here, we show the compounding effect of stomatal regulation and hydraulic capacitance on plant water use, by means of a soil–plant hydraulic model and measurements of leaf water ...

Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

open access: yesChemistry – A European Journal, Volume 32, Issue 17, 5 May 2026.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.
