Activating a Metallization Switch for Record Hydrogen Evolution in Single‐Atom Modified Polar MOF Piezocatalysts

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Piezocatalytic hydrogen evolution enables the conversion of mechanical energy into chemical fuels, but its efficiency is constrained by a trade‐off between piezoelectric polarization and electronic conductivity. Strong piezoelectric polarization is essential for sufficient driving force, yet highly polar materials typically suffer from poor ...

Le primitif et le mystique chez Lévy-Bruhl, Bergson et Bataille

open access: yesMethodos, 2004
French human sciences at the beginning of the 20th century used to assimilate the figures of the mad person, the primitive and the child. The Author shows that this assimilation should not be interpreted in the sense of an opposition between the archaic ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

Context‐Dependent Role of GDF15: GDF15+ Tumor‐Associated Macrophages Suppress OSCC Progression by Enhancing Phagocytosis

open access: yesAdvanced Science, EarlyView.
This study identifies GDF15+ TAMs as a cell subset mediating tumor regression after immunotherapy. Macrophage‐intrinsic GDF15 enhances phagocytosis and antigen cross‐presentation to CD8+ T cells through the NF‐κB signaling pathway, thereby inhibiting tumor progression.

A Cascade Recognition of Activatable Probe for Fluorescence Navigation Glioblastoma Surgery: Overcoming Blood‐Brain Barrier and Off‐Target Limitations

open access: yesAdvanced Science, EarlyView.
A cascade recognition of activatable probe ANG‐hCy‐MC is used for high‐precision depiction of glioblastoma (GBM) margin. This probe crosses the blood‐brain barrier (BBB) through LRP1 receptor‐mediated transport and provides excellent fluorescence signal contrast between the tumor and normal tissues, thereby enabling ultra‐selective imaging and precise ...

Self-Sacrifice and the Sacred: Edith Stein on Phenomenology, Christianity, and Mysticism

open access: yesReligions
In Edith Stein’s thinking, there is a gradual transition from the discovery of Christianity in her phenomenological studies to the mystical realization of her own role as a Christian.

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis

open access: yesAdvanced Science, EarlyView.
Additive and partially dominant effects, namely at mid‐parent levels or values between mid‐parent and parental levels, respectively, are the predominant inheritance patterns of heterosis‐associated molecules. These two genetic effects contribute to heterosis of agronomic traits in both rice and maize, as well as biomass heterosis in Arabidopsis ...

Control Strategies in Guanine Biocrystallization

open access: yesAngewandte Chemie, EarlyView.
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

THE CYCLE FOR PIANO ILLUSIONS BY VLADIMIR CIOLAC: COMPOSITIONAL ASPECT [PDF]

open access: yesStudiul Artelor şi Culturologie: Istorie, Teorie, Practică, 2021
In the pages of the artice, we propose for the first time an analysis of the cycle for piano „Illusions” by V. Ciolac dedicated to his composition teacher P. Rivilis. The work is made up of four parts, which develop predominantly in slow tempo, the basic
