Revista Discusiones, 2003 Los objetivos de mi comentario son dos. Primero, poner de relieve que, además de las concepciones persuasiva y cognoscitivista de la prueba que distingue Taruffo, cabe identificar una tercera concepción que, a los fines de racionalidad de la decisión ...

Advanced Functional Materials, EarlyView.Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Advanced Functional Materials, EarlyView.MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

El presidente de Colombia y su elusión constitucional en época de crisis
Novum JusEl uso y abuso del estado de sitio en Colombia fue una constante durante los siglos XIX y XX. Por ello, el Constituyente de 1991 fue tan cuidadoso a la hora de regular los estados de excepción estableciendo un sistema de exigentes límites y controles ...

Determination of Residual Monomers Released from Soft Lining Materials with the use of HPLC [PDF]
Pakistan Journal of Analytical & Environmental Chemistry, 2007 A study was carried out to examine the post polymerized leachability of three non phthalic and four phthalic residual monomers, from twelve commercially available soft lining materials, using HPLC. Specimens of equal dimensions were constructed from each

Mechanically Stable and Tunable Photoactivated Peptide‐Based Hydrogels for Soft Tissue Adhesion
Advanced Functional Materials, EarlyView.A collagen‐like peptide hydrogel platform is developed using supramolecular self‐assembly and light‐triggered crosslinking. It creates mechanically stable, tunable hydrogels with cytocompatibility and biodegradability, making them potential soft tissue adhesives.

Physique de l’espace et phénoménologie de l’espace
Philosophia Scientiæ, 2011 What is space ? Why is there space rather than nothing ? Nowadays Physics claims to answer these questions without making any reference to the phenomenal space of the subject, and thus in total rupture with respect to its phenomenological meaning.

Advanced Functional Materials, EarlyView.This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

La Fiscalidad Internacional – (Amenazas y Oportunidades en un Entorno Competitivo)
Iuris Tantum, 2003 Dos de las amenazas más importantes con los que se ha encontrado la tributación internacional a lo largo de la historia, consisten en los problemas derivados de la doble tributación, por un lado y de la evasión o elusión fiscal, por el otro.
