Modelització del deflectòmetre d'impacte amb el mètode dels elements finits i les partícules [PDF]

open access: yes, 2011
El deflectòmetre d’impacte segurament és l’aparell més utilitzat per realitzar assaigs no destructius dels ferms. Els enginyers utilitzen el deflectròmetre d’impacte per estimar els mòduls elàstics de les diferents capes que conformen el ferm assumint ...

Verbesserter Stofftransport und Ladungstransfer in COF‐basierten Photokatalysatoren mit dreidimensional geordneten Makroporen für die Benzylaminoxidation und Wasserstoffentwicklung

open access: yesAngewandte Chemie, Volume 137, Issue 34, August 18, 2025.
Ein einstufiges, selbstopferndes Templating ermöglicht die Synthese von 3DOM‐COFs mit geordneten Makroporen. In Kombination mit ZnCdS katalysiert das daraus resultierende S‐Schema‐Heterojunktion effizient die Oxidation von Benzylamin und die H₂‐Entwicklung.

Arithmetical pluralism and the objectivity of syntax

open access: yesNoûs, Volume 59, Issue 2, Page 372-391, June 2025.
Abstract Arithmetical pluralism is the view that there is not one true arithmetic but rather many apparently conflicting arithmetical theories, each true in its own language. While pluralism has recently attracted considerable interest, it has also faced significant criticism.

Fluorescent Probe for δ‐Cyclodextrin Enables Guest Encapsulation Studies via an Indicator Displacement Assay

open access: yesChemistryEurope, Volume 3, Issue 3, May 2025.
A molecular probe that partially unfolds and exhibits fluorescence enhancement upon binding to δ‐cyclodextrin (δ‐CD) is presented. Its implementation in a fluorescence indicator displacement assay to test the binding of various guest to δ‐CD is demonstrated.

Stochastic thermodynamics for biological functions

open access: yesQuantitative Biology, Volume 13, Issue 1, March 2025.
Abstract Living systems operate within physical constraints imposed by nonequilibrium thermodynamics. This review explores recent advancements in applying these principles to understand the fundamental limits of biological functions. We introduce the framework of stochastic thermodynamics and its recent developments, followed by its application to ...

A Concrete Resistivity Method Based on a Simple Measuring Cell for Onsite Corrosion Monitoring: Study on Concrete Under Varying Conditions

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Concrete resistivity (ρ) is commonly monitored in situ using sensors based on the rebar‐disc (RDM) or four‐electrode (FEM) methods. This study validates, for the first time in reinforced concrete, an innovative corrosion sensor approach (CSA) previously tested only in simulated pore solutions.
