Slow crack growth in polycarbonate films [PDF]

open access: yes, 2005
We study experimentally the slow growth of a single crack in polycarbonate films submitted to uniaxial and constant imposed stress. The specificity of fracture in polycarbonate films is the appearance of flame shaped macroscopic process zones at the tips

Cottonseed‐Derived Reusable Bio‐Carbon Gel Ink for DIW Printing Soft Electronic Textiles

open access: yesAdvanced Materials, EarlyView.
A reusable carbon‐gel ink, incorporating cottonseed peptone as a natural mediator, enables cross‐linked ionic polymer networks for advanced conductivity, stability, and biocompatibility. Compatible with direct‐ink‐writing, it facilitates flexible electronics on polymeric and textile substrates for multifunctional applications, including motion sensing,

Copper Catalysts Inherit and Retain Precatalyst Morphology in Extended CO Electroreduction to n‐Propanol

open access: yesAdvanced Materials, EarlyView.
Flash Joule heating enables the formation of quenched Cu oxide precatalysts with intragrain‐in‐grain architectures. These hierarchical structures are inherited after electroreduction, suppressing reconstruction even at high current densities in an MEA cell.

Drastic Mechanochromic Luminescence Through Fluorescence–Phosphorescence Switching in a Heavy‐Atom‐Free Organoboron Compound

open access: yesAdvanced Optical Materials, EarlyView.
A new heavy‐atom‐free, donor–acceptor‐type organoboron luminophore has been synthesized, which exhibits red room‐temperature phosphorescence (RTP) in the crystalline state. Furthermore, the amorphous solid generated by grinding shows green thermally activated delayed fluorescence (TADF), displaying distinct mechanochromic luminescence (MCL) through ...

Ultima Ratio as a Constitutional Principle

open access: yesOñati Socio-Legal Series, 2013
The paper argues the criminal law notion of ultima ratio is an instance of a broader constitutional law principle of proportionality. However, ultima ratio is not the only principle relevant in a constitutional assessment of criminalization.

Accounting for ALA Natural Mutations Enhances the Efficiency of Graphene Oxide Nanopriming in Bar‐Modified Arabidopsis

open access: yesAdvanced Science, EarlyView.
Nanopriming enhances plant resilience to environmental challenges; however, its effectiveness across diverse genetic backgrounds, including genetic modifications and natural variations, remains uncertain. These findings demonstrate that nanopriming improves efficacy when natural genetic variations are considered, particularly in genetically modified ...

Ultima Ratio in European Criminal Law

open access: yesOñati Socio-Legal Series, 2012
The ultima ratio principle is one of the most well known traditional principles of criminal law. The principle has emphasized the repressive nature of the criminal justice system and positioned it as the last resort of the legislator.

Acoso y Derecho penal [PDF]

open access: yes, 2014
A pesar de las recientes reformas, la falta de una tipificación propia del acoso en general continúa siendo una insuficiencia del Derecho español, a la que convendría poner remedio siguiendo los mejores ejemplos del Derecho comparado.

Glucose‐Responsive PAGR1‐Regulated Skeletal Muscle Gene Program Controls Systemic Glucose Homeostasis and Hepatic Metabolism

open access: yesAdvanced Science, EarlyView.
The study reveals that PAXIP1‐associated glutamate‐rich protein 1 (PAGR1), a glucose‐responsive regulator in skeletal muscle, modulates systemic glucose homeostasis and hepatic metabolism. Muscle‐specific PAGR1 deletion enhances insulin signaling, promotes glucose transporter 4 (GLUT4) translocation, and protects against high‐fat‐diet‐induced insulin ...
