Effect of Humidity on Ionisation and Ion Chemistry in Active‐Capillary Dielectric Barrier Discharge Ionisation

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...

Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

open access: yesEcography, Volume 2026, Issue 6, June 2026.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 9, 5 May 2026.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Blind Testing: DNA Barcoding Sheds Light Upon the Identity of Plant Fragments as a Subsidy for Cave Conservation

open access: yesFrontiers in Plant Science, 2018
Plants living above and around caves represent an important, albeit poorly studied, resource within cave ecosystems. The presence of plant material (root-like structures or rhizothemes, saplings, seeds, and seedlings) correlates positively with the ...

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

open access: yesRestoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.
