Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Biomass‐Derived Hetero Atom‐Doped Porous Carbon for Enhanced CO2 Adsorption

open access: yesMetalMat, EarlyView.
This review discusses the synthesis and characterization of the heteroatom (N, S, P, O, B)‐doped porous carbon materials which are specifically designed for the CO2 capture and CO2 conversion to value‐added products. ABSTRACT The emission of carbon dioxide (CO2) and its impact on global warming have shown exponential growth in recent decades.

Ectomycorrhizal fungi and root water uptake respond independently to water availability

open access: yesOikos, EarlyView.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, EarlyView.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...

Exploring young people's visual perceptions of nature on urban school grounds: Insights from a visitor‐employed photography walk for environmental education

open access: yesPeople and Nature, EarlyView.
Abstract Urban growth and densification increasingly limit children's and young people's access to natural environments. Since they spend a considerable amount of time within school grounds and their immediate surroundings during their childhood, daily encounters with nature are often closely linked and restricted to these environments.
