Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Species complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species‐based scientific questions,

Photosynthesis of NH3 from NO3− Using CH4 in Homogenous Rhenium Catalysis

open access: yesAngewandte Chemie, EarlyView.
We present a Re catalysis of one‐pot synthesis of NH3 from NO3− using CH4 as a reductant under UV light irradiation. We are able to directly convert NO3−, leading to several environmental issues, to NH3, an essential compound as a fertilizer and industrial raw material, by means of CH4, which has a high affinity with renewable resource/energy, as a ...

“Someday, I'll be an ancestor:” Understanding indigenous intergenerational connectedness through qualitative research to inform measure development

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Intergenerational connectedness broadly encompasses relations among humans, lands, and all living and spiritual beings, and functions as an important part of Indigenous well‐being. Many public health campaigns and interventions aim to promote connectedness to support holistic wellness and reduce health inequities. Currently, however, there are

Regulating Multifunctional Oxygen Vacancies for Plasma‐Driven Air‐to‐Ammonia Conversion

open access: yesAngewandte Chemie, EarlyView.
High defective Fe2O3 nanoparticles on Cu synthesis by plasma introduced multifunctional oxygen vacancies achieving 100% NH3 selectivity through a plasma‐electrochemical system capable of directly reducing air to gaseous NH3. Abstract Current ammonia (NH₃) synthesis is hindered by challenges including N₂ activation, NH₃ separation and process complexity.
