Determination of surfactant bio-sourced origin by isotope-ratio mass spectrometry.

Rapid communications in mass spectrometry : RCM

Gaubert A, Jame P, Bordes C, Clément Y, Guibert S, Batteau M, Lomberget T, Anchisi A, Lantéri P, Casabianca H.
PMID: 27060838
Rapid Commun Mass Spectrom. 2016 May 15;30(9):1108-14. doi: 10.1002/rcm.7537.

RATIONALE: To develop more eco-friendly laundry detergents, renewable surfactants synthesized from vegetal sources are increasingly being used. In a more stringent regulation context, the determination of bio-sourced surfactant origin thus appears essential to assess the claims of detergent manufacturers....

Laser synthesized TiO.

Science and technology of advanced materials

Bouhadoun S, Guillard C, Sorgues S, Hérissan A, Colbeau-Justin C, Dapozze F, Habert A, Maurel V, Herlin-Boime N.
PMID: 29152015
Sci Technol Adv Mater. 2017 Oct 25;18(1):805-815. doi: 10.1080/14686996.2017.1379858. eCollection 2017.

Titanium dioxide nanoparticles were synthesized by laser pyrolysis, their surface and electronic properties were modified by gold and/or nitrogen. These materials were characterized by different techniques like X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR)....

Anatomic reconstruction of the medial patellofemoral ligament using the fascia lata as an autograft.

Arthroscopy techniques

Haupert A, Lorbach O.
PMID: 25973375
Arthrosc Tech. 2015 Feb 09;4(1):e57-63. doi: 10.1016/j.eats.2014.11.005. eCollection 2015 Feb.

The medial patellofemoral ligament (MPFL) ensures stability of the patella against lateral forces. In cases of recurrent lateral patellar luxation, surgical reconstruction of the MPFL has an important role in treating lateral patellar instability. Several biomechanical studies have presented...

Influence of cross sectional geometry on surface plasmon polariton propagation in gold nanowires.

ACS nano

Nauert S, Paul A, Zhen YR, Solis D, Vigderman L, Chang WS, Zubarev ER, Nordlander P, Link S.
PMID: 24308802
ACS Nano. 2014 Jan 28;8(1):572-80. doi: 10.1021/nn405183r. Epub 2013 Dec 10.

We investigated the effects of cross sectional geometry on surface plasmon polariton propagation in gold nanowires (NWs) using bleach-imaged plasmon propagation and electromagnetic simulations. Chemically synthesized NWs have pentagonally twinned crystal structures, but recent advances in synthesis have made...

Evolutionary prisoner's dilemma games with voluntary participation.

Physical review. E, Statistical, nonlinear, and soft matter physics

Szabó G, Hauert C.
PMID: 12513331
Phys Rev E Stat Nonlin Soft Matter Phys. 2002 Dec;66(6):062903. doi: 10.1103/PhysRevE.66.062903. Epub 2002 Dec 18.

Voluntary participation in public good games has recently been demonstrated to be a simple yet effective mechanism to avoid deadlocks in states of mutual defection and to promote persistent cooperative behavior. Apart from cooperators and defectors a third strategical...

Self-organized criticality in a nutshell.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Nagler J, Hauert C, Schuster HG.
PMID: 11970072
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Sep;60(3):2706-9. doi: 10.1103/physreve.60.2706.

In order to gain insight into the nature of self-organized criticality (SOC), we present a minimal model exhibiting this phenomenon. In this analytically solvable model, the state of the system is fully described by a single-integer variable. The system...

PMID: 17404992
Planta Med. 1983 Aug;48(8):258-62. doi: 10.1055/s-2007-969929.

Cell-free extracts from acridone synthesizing cell suspension cultures of RUTA GRAVEOLENS L. catalyze the N-methylation of anthranilic acid using S-adenosyl-L-methionine as methyl donor. The stability of enzyme preparations was remarkably high during storage at -20 degrees C. Optimum activity...

Absolute measurement of molecular two-photon absorption cross-sections using a fluorescence saturation technique.

Optics express

Kauert M, Stoller PC, Frenz M, Ricka J.
PMID: 19529221
Opt Express. 2006 Sep 04;14(18):8434-47. doi: 10.1364/oe.14.008434.

We have developed a fluorescence saturation technique for accurate measurements of the absolute molecular two-photon absorption (TPA) cross-section of fluorescent dyes. We determine the TPA crosssection both from measurements at excitation intensities well below saturation onset (in the square...

Marshall and Brown (2006) proposed a Traits as Situational Sensitivities (TASS) Model, which implies a systematic person × situation interaction. We review this model and show that it suffers from several limitations. We extend and modify the model in...
