Conductivity and microstructural evaluation of SGDC solid electrolytes synthetized by Pechini and controlled precipitation

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2022
In this work, controlled precipitation synthesis methods and polymeric precursors (Pechini) were used to obtain gadolinium-doped cerium oxide solid electrolytes (Ce0.8Gd0.2O1.9) and double-doped cerium oxide with gadolinium and samarium (Ce0.8Gd0.2 ...

Floral stage optimization and immune evasion enhance Agrobacterium‐mediated genome editing in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 2125-2139, February 2026.
Summary Agrobacterium‐mediated transformation by floral inoculation (AMT‐FI) enables genetic engineering without tissue culture. It is widely used in the model plant Arabidopsis thaliana, yet its efficiency and broader applicability remain limited. Here, we used a dual‐reporter system (RUBY and hygromycin resistance) to identify key floral stages and ...

Contradição e antagonismo: o funcionamento do léxico na mídia

open access: yesLinha D'Água, 2014
Na perspectiva teórica, a que nos filiamos, os sujeitos, os sentidos e a língua escapam ao gerenciamento social e político dos sujeitos e das instituições. Por esse viés, o discurso é uma prática política ligada a sujeitos e a ideologias, e o sentido das

Programmable Microscale Actuation of Hydrogels With Tunable Response via Printing on Particles

open access: yesAdvanced Materials Technologies, Volume 11, Issue 1, 8 January 2026.
We fabricate microscale hydrogels with precisely tunable phase transition temperatures (23–60 °C) by particle‐templated two‐photon polymerization using chemically tailored inks. Multi‐material printing enables stepwise thermal actuation through sequential volume changes at distinct VPTTs, while pH‐dependent hysteresis drives anisotropic actuation with ...

Theoretical Perspectives on the Minimal and Narrative Self in the Schizophrenia Spectrum: An Integrative Review

open access: yesWIREs Cognitive Science, Volume 17, Issue 1, January/February 2026.
The links between the minimal self (our most basic sense of being) and the narrative self (our personal story and identity) in schizophrenia are still unclear. They may work in three ways: the minimal self affecting the narrative self, both influencing each other, or both shaped by the person's context.

The Impact of Climate and Land Cover Change on the Cryosphere and Hydrology of the Mackenzie River Basin, Canada

open access: yesWater Resources Research, Volume 61, Issue 12, December 2025.
Abstract Northern basins are projected to continue warming at rates higher than the global average, with the impacts of warming compounded by concomitant deglaciation, permafrost thaw and vegetation shifts. The Mackenzie River Basin drains headwaters in the glaciated Canadian Rockies to the Arctic Ocean and is mostly underlain by permafrost.
