Isolating and Measuring the Growth and Morphology of Pro-embryogenic Masses in Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae)

open access: yesBio-Protocol, 2016
Embryogenic suspension cultures of Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae) can be used as a model to test the effects of compounds added to the culture medium on the cellular growth and morphology of Pro-Embryogenic Masses (PEMs).

Main‐Chain Ion‐Pair Polybenzimidazole Membranes Enabling Reduced‐Temperature HT‐PEMFC Operation (Down to 120°C)

open access: yesAdvanced Energy Materials, EarlyView.
Embedding imidazolium‐biphosphate ion pairs directly into the polybenzimidazole main chain simultaneously stabilizes phosphoric acid and preserves continuous proton transport pathways. Strong ion‐pair and hydrogen‐bond interactions suppress acid leaching while maintaining high conductivity, enabling stable and durable high‐temperature fuel cell ...

Complex Iridium Oxides Converge In Structure And Reactivity During Acidic Oxygen Evolution Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Ir‐based double perovskites restructure during acidic oxygen evolution electrocatalysis through dissolution of non‐Ir cations and convergence toward IrOx active‐site motifs with similar structure and intrinsic activity across compositions. The identity of the dissolving cations controls dissolution and surface reconstruction kinetics, clarifying how ...

Microplastic influences the ménage à trois among the plant, a fungal pathogen, and a plant growth-promoting fungal species

open access: yesEcotoxicology and Environmental Safety
Microplastics (MP) can influence a plethora of fungal species within the rhizosphere. Nevertheless, there are few studies on the direct impacts of MPs on soil fungi and their intricate interplay with plants.
