Understanding and predicting the viscoelastic response of polymer melts or concentrated solutions from the knowledge of molecular architecture represents a very active field of research with important challenges. Our first objective is to develop a general coarse-grained model for predicting the viscoelastic properties of linear and branched polymers. Based on the tube theory proposed by de...
Brownian relaxation in colloidal suspensions has been observed in different susceptibilities such as shear moduli, viscosities or diffusion coefficients [1-6]. We present Brownian relaxation times obtained by Small Angle Oscillatory Shear (SAOS) measurements on suspensions consisting of two types of a low-molecular weight glass former (Diglycidyl Esther of Bisphenol A) filled with silica...
Hadron therapy is increasing worldwide for treating some radio-resistant tumours due to its more advantageous depth dose deposition, less lateral spread and better sparing of healthy tissues close to the irradiated target as compared to photon or electron beams. Besides these favourable physical properties, ion beams offer potential biological advantages over protons making them even more...
In this work, we describe a novel tool for monitoring the quality of cell cultures in terms of contamination and genomic stability in real time. The proposed platform, the so-called heat-transfer method (HTM), enables to monitor the heat-transfer resistance at solid-liquid interfaces in real-time.1 Previously, it was shown that it is possible to detect cells in buffer solution in a fast,...
Thiol self-assembled monolayers (SAMs) are popular due to their utility for various applications. In biosensing platforms SAMs are often used as linkers to tether receptors to biochip surfaces [1]. To get a full understanding of SAM-properties, it is important to study also their formation kinetics and thermal-transport properties. This latter point was not addressed before. However, it is...
Unraveling the immense complexity of the human brain requires the ability to selectively interfere and record neural activity. ‘Optogenetics’ describes a variety of techniques for specifically controlling neural activity with light, using light sensitive membrane proteins (opsins).1 Given the significant advantages of nonlinear optics, activating opsins by two-photon absorbance is already an...
We show how to formulate linear thermodynamics for periodic driving including small scale systems. In particular, we derive generalized Onsager-Casimir relations.
Norton's dome is an example of indeterminism in Newtonian physics, based on a differential equation involving a non-Lipschitz continuous function [1]. It involves a gravitational field, in which a mass is placed with velocity zero at the apex of a dome (x=0,v=0), which has the following shape:
y(x)=−2/3(1−(1−3/2|x|)2/3)3/2.
Besides the trivial, singular solution, r(t)=0 (where r is the arc...
