Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

The "Dryopteris dilatata complex in Macaronesia and the Iberian Peninsula [PDF]

open access: yes, 1983
Diploid and tetraploid species of the Dryopteris dilatata complex are found in Spain and Portugal. In an attempt to determine the relationships between species the cytology of both wild and synthetised hybrids has been investigated, and the results ...

New opportunities for grassland species in warming temperate winters

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Temperate winters are getting warmer, the length of the growing season is increasing and mid‐winter fluctuations of warm and freezing temperatures are more frequent. Although typically winter dormant, some herbaceous perennials can maintain or grow green leaves during ...

Renewal bud traits as a link between whole plant traits and herbaceous species phenology

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Overwintering below‐ground buds and organs determine spring regrowth of perennial herbs in temperate regions. This effect could also manifest further in the timing and duration of plant growth and flowering and has been documented in some species and organ types ...

Kinship through code, personhood as node: AI afterlives and new technologies of the self Parenté par le code, personne nodale : vie posthume dans l'IA et nouvelles technologies du moi

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
This article examines how emerging generative AI technologies in Europe and North America are being used to reanimate the dead, prompting users to define the ‘edges’ of self and personhood through coding practices. These technologies invite new engagements with fundamental questions of relatedness and the construction of the self, challenging and ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Automated quantification of fine root production from minirhizotron image time series

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Plant root growth accounts for a major part of the net primary production in grassland and forest ecosystems and influences the global carbon and nutrient cycles. Measuring the production of roots is inherently difficult, prone to inconsistencies and time‐consuming. Notably, there are currently no methods yet to automate this task.

Enhancing the vase life of cut roses through spectral optimisation during greenhouse cultivation

open access: yesAnnals of Applied Biology, EarlyView.
Here, we examined three red‐to‐blue (R:B) light emitting diode (LED) ratios (90:10, 80:20 and 70:30) in two cut rose cultivars. All treatments enhanced photosynthesis, with 90:10 showing the strongest effects—raising chlorophyll, carotenoids, anthocyanins and carbohydrate levels, and extending vase life by up to 30%.
