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.

Numerical investigations on the influence of the nominal hole clearance on the plate resilience of high strength preloaded bolted joints Numerische Untersuchungen zum Einfluss des Nennlochspiels auf die Plattennachgiebigkeit von hochfest vorgespannten Schraubenverbindungen

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 55, Issue 12, Page 1687-1706, December 2024.
Zur Erhöhung des Nennlochspiels kommen in geschraubten Verbindungen häufig Langlöcher zum Einsatz. Um dennoch eine reibschlüssige Tragwirkung gewährleisten zu können, muss u. a. ein Hineinziehen der Scheiben in das Langloch vermieden werden. Slotted holes are often used in bolted connections to increase the nominal hole clearance.

Hidromechanical simulation in a fractured rock mass: the experimental site of Coaraze (Southern-Alps, France) [PDF]

open access: yes, 2004
Hydromechanical processes in large permeable jointed rock masses have been poorly studied due to the difficulties in determining boundary conditions in such large sites.
