Membrane‐Targeted Nanoparticles for Neuronal Photomodulation

open access: yesAdvanced Science, EarlyView.
Immobilizing gold nanoparticles on the neural interface using a bioorthogonal approach generates localized heat upon exposure to near‐infrared light, temporarily inhibiting primary neuronal activity without damaging the cells. This precise placement and retention of nanoparticles at the cell membrane expand the strategies for non‐invasive neural ...

Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study

open access: yesHepatology, EarlyView., 2022
Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study. Abstract Background and Aims Alagille syndrome (ALGS) is a multisystem disorder, characterized by cholestasis. Existing outcome data are largely derived from tertiary centers, and real‐world data are lacking.

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

open access: yesAdvanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Comunicación de la ciencia 2.0 en España: El papel de los centros públicos de investigación y de medios digitales [PDF]

open access: yesRevista Mediterránea de Comunicación, 2015
España es uno de los países europeos con menor cultura científica, a lo que se suma un descenso de las vocaciones científicas en los últimos diez años. Internet se erige como el principal canal para acercar la ciencia a los nativos digitales y revertir esta situación.

Controllable Superconductivity in Suspended NbSe2

open access: yesAdvanced Electronic Materials, EarlyView.
Suspended NbSe2${\rm NbSe}_2$ provides two complementary routes for controlling superconducting transport. Gate‐driven deformation strains the suspended crystal and tunes its critical temperature and current. Weak thermal anchoring enhances thermal feedback, contributing to multistep hysteresis and negative differential resistance.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Environmental and Genetic Effects on the Composition of Palm Oil From Hybrid Plant Clones of Caiaué and Oil Palm

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The interspecific hybrids (IEH OxG) obtained from the crossing of Elaeis oleifera (Eo) and Elaeis guineensis (Eg) are resistant to some diseases that affect Eg in some regions of South America, and commercial growing in several countries has been established.

Fabrication‐Aware Mechanical Design of SLA‐Printed Polymeric Microneedles: Integrating Geometry, Dimensional Fidelity, and Structural Instability

open access: yesJournal of Applied Polymer Science, EarlyView.
SLA‐printed microneedles exhibit fabrication‐induced dimensional deviations that strongly influence their mechanical response. Comparison of nominal CAD, global as‐printed, and local critical‐section models shows that local tip‐region geometry provides the closest agreement with experimental instability loads, highlighting the importance of fabrication‐
