Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Priority areas for arthropod conservation in the Iberian Peninsula and Balearic Islands: Insights from a multi‐taxon distributional database

open access: yesInsect Conservation and Diversity, EarlyView.
Using over 416,000 occurrence records from 13 arthropod groups (6233 arthropod species), we mapped large‐scale richness patterns and identified biodiversity hotspots across the Iberian Peninsula and Balearic Islands. Hotspot congruence among arthropod groups was low, underscoring the importance of integrative, multi‐taxon approaches for conservation ...

The plant growth-promoting effect of an Ascophyllum nodosum (L.) extract derives from the interaction of its components and involves salicylic-, auxin- and cytokinin-signaling pathways

open access: yesChemical and Biological Technologies in Agriculture
Background Ascophyllum Nodosum (L.) Extracts (ANE), even at low concentrations, are reported to behave as plant growth promoters and inducers of resistance to diverse abiotic and biotic stresses.

Inorganic mercury (Hg2+) uptake by different plankton fractions of Andean Patagonian lakes (Argentina)

open access: yesE3S Web of Conferences, 2014
The species composition and the size structure of natural planktonic food webs may provide essential information to understand the fate of mercury and, in particular, the bioaccumulation pattern of Hg2+ in the water column of lake ecosystems ...

Symbiosis‐associated UMAMIT transporters required for establishing efficient nitrogen fixation in Medicago truncatula

open access: yesNew Phytologist, Volume 250, Issue 1, Page 530-546, April 2026.
Summary To address a critical gap in understanding amino acid transport in legume–Rhizobium symbiosis, we investigated the role of symbiosis‐associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation.

Do's and Don'ts When Visiting Circularly Polarized Luminescence

open access: yesAdvanced Optical Materials, Volume 14, Issue 11, 20 March 2026.
This perspective presents our insights into the principles, challenges, and opportunities of circularly polarized luminescence (CPL). Highlighting key concepts such as the dissymmetry factor (glum) and molecular design strategies, we discuss advances in CPL efficiency, emerging NIR emitters, solid‐state applications, and the growing role of theory and ...

Net CO2 Emissions From Dry Inland Waters Persist in the Presence of Vegetation

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract Many inland waters are shrinking due to shifts in climate and water diversion for human uses. As they dry out, their exposed sediments emit large amounts of carbon dioxide (CO2) to the atmosphere. However, current global estimates of CO2 emissions from dry inland waters are derived exclusively from bare sediment dark‐chamber measurements that ...
