Phosphorus desorbability in soils with andic properties from the Azores, Portugal Desorção de fósforo em solos com propriedades ândicas do Arquipélago dos Açores (Portugal)

open access: yesRevista de Ciências Agrárias, 2009
Desorbability of phosphorus (P des) at P sorption maxima in eighteen horizons (surface and subsurface) of soils with andic properties from the Azores, Portugal, was determined by eight successive extractions using distilled water (H2O), calcium chloride (

Thickness Dependence of Linear and Nonlinear Optical Properties of Multilayer 3R‐MoS2

open access: yesAdvanced Optical Materials, EarlyView.
Thickness as a key design parameter for optimizing the nonlinear optical response of layered transition metal dichalcogenides (TMDs) materials is established. The demonstrated correlation between thickness, linear spectra, and harmonic generation efficiency provides a powerful framework for tailoring nonlinear performance.

An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring

open access: yesAdvanced Science, EarlyView.
Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...

Dual Targeting of Tau Kinases and Autophagy by Abemaciclib Independent of CDK4/6 Inhibition

open access: yesAdvanced Science, EarlyView.
Abemaciclib rescues cognitive function and attenuates tau pathology in Alzheimer's disease models, but not through its known cancer‐fighting mechanism. This study demonstrates that abemaciclib operates independently of CDK4/6 inhibition, instead directly targeting tau kinases CaMKII and GSK3β while simultaneously promoting autophagic clearance of ...
