Light-induced demixing of hole or electron transporting moieties

2004

This paper describes the synthesis of two tri-phenylamine monomers (hole conducting) and one triazine monomer (electron conducting) which differ in their copolymerization parameters because of their styrene and vinyl ester nature. A blend of triphenylamine monomer and poly-(ethylene glycol) and mixtures of both types of monomers (triphepylamine and triazine) were illuminated through a line mask, creating laterally modulated radicals, thus leading to lateral demixing. The experiments with mixtures of triphenylamine and triazine monomers show that the concentration of p- or n-type polymers can be modulated laterally in a controlled way.

Methyl-3-Hexenoate Combustion Chemistry: Experimental Study and Numerical Kinetic Simulation

2020

International audience; This work represents a detailed investigation of combustion and oxidation of methyl-3-hexenoate (CAS Number 2396-78-3), including experimental studies of combustion and oxidation characteristics, quantum chemistry calculations and kinetic model refinement. Following experiments have been carried out: Speciation measurements during oxidation in a jet-stirred reactor at 1 atm; chemical speciation measurements in a stoichiometric premixed flame at 1 atm using molecular-beam mass-spectrometry; ignition delay times measurements in a shock tube at 20 and 40 bar; and laminar burning velocity measurements at 1 atm using a heat-flux burner over a range of equivalence ratios. …

Performing Sound of the Past: Remix in Electronic Dance Music Culture

2014

The term remix, defined as an activity of taking data from pre-existing materials to combine them into new forms according to personal taste, relates to various elements and areas of contemporary culture. Whichever model used, consideration of the remix depends on recognition of pre-existing cultural codes. Therefore, as a second layer, the remix relies on the authority of the original and it functions at the meta-level. The audience may see a trace of history with the pre-existing object and the meaning creates in the viewer(s), reader(s), listener(s) or, in the contemporary world of DJs and popular electronic dance music culture – in dancer(s). With the aim of specifying modes of creating…

Protein crystallization: universal thermodynamic vs. specific effects of PEG

2008

The interest of nucleation of protein crystals and aggregates (including oligomerization) spans from basic physics theory all the way to biophysics, nanophysics, clinical sciences, biotechnologies, food technologies and polymer–solvent interactions. Understanding nucleation within a theoretical framework capable of providing quantitative predictions and control of nucleation rates, or even the very occurrence of crystallization, is a long-sought goal of remarkable relevance to each of the above fields. A large amount of work has been aimed at such goal, but success has been so far rather limited. Work at our laboratory has more recently highlighted a direct link between nucleation rates and…
