Adsorption and onset of lubrication by a double-chained cationic surfactant on silica surfaces.

Journal of colloid and interface science

Serreau L, Beauvais M, Heitz C, Barthel E.
PMID: 19200555
J Colloid Interface Sci. 2009 Apr 15;332(2):382-8. doi: 10.1016/j.jcis.2008.12.065. Epub 2009 Feb 05.

In the context of glass fiber manufacture, the onset of lubrication by a C(18) double-chained cationic surfactant has been investigated at high normal contact pressures. Comparison with adsorption kinetics demonstrates that lubrication is not directly connected to the surfactant...

Approaches to transition in other chronic illnesses and conditions.

Pediatric clinics of North America

Betz CL.
PMID: 20883887
Pediatr Clin North Am. 2010 Aug;57(4):983-96. doi: 10.1016/j.pcl.2010.07.017.

This article provides information about the efforts to develop health care transition programs in four groups of patients: those with cystic fibrosis, spina bifida, and congenital heart disease, and childhood cancer survivors. Against the backdrop of information on prevalence,...

Characterization of pyrgeometers and the accuracy of atmospheric long-wave radiation measurements.

Applied optics

Philipona R, Fröhlich C, Betz C.
PMID: 21037701
Appl Opt. 1995 Mar 20;34(9):1598-605. doi: 10.1364/AO.34.001598.

A detailed characterization is performed to calibrate pyrgeometers, using a newly developed apparatus that contains a blackbody radiation source and the means to vary the temperatures of the pyrgeometer under testing. Calibration measurements cover the parameter space of radiation...

Tailoring magnetic interlayer coupling in La0.7Sr0.3MnO3/SrRuO3 superlattices.

Physical review letters

Ziese M, Vrejoiu I, Pippel E, Esquinazi P, Hesse D, Etz C, Henk J, Ernst A, Maznichenko IV, Hergert W, Mertig I.
PMID: 20482078
Phys Rev Lett. 2010 Apr 23;104(16):167203. doi: 10.1103/PhysRevLett.104.167203. Epub 2010 Apr 21.

The magnetic interlayer coupling in La0.7Sr0.3MnO3/SrRuO3 superlattices was investigated. High quality superlattices with ultrathin La0.7Sr0.3MnO3 and SrRuO3 layers were fabricated by pulsed laser deposition. The superlattices grew coherently with Mn/Ru intermixing restricted to about one interfacial monolayer. Strong antiferromagnetic...

Abnormal calcium homeostasis and protein folding stress at the ER: A common factor in familial and infectious prion disorders.

Communicative & integrative biology

Torres M, Encina G, Soto C, Hetz C.
PMID: 21980554
Commun Integr Biol. 2011 May;4(3):258-61. doi: 10.4161/cib.4.3.15019.

Prion-related disorders (PrDs) are caused by the accumulation of a misfolded and protease-resistant form of the cellular prion, leading to neuronal dysfunction and massive neuronal loss. In humans, PrDs have distinct etiologies including sporadic, infectious and familial forms, which...

Flow-induced control of chemical turbulence.

The Journal of chemical physics

Berenstein I, Beta C.
PMID: 22047263
J Chem Phys. 2011 Oct 28;135(16):164901. doi: 10.1063/1.3656248.

We report spatiotemporal chaos in the Oregonator model of the Belousov-Zhabotinsky reaction. Spatiotemporal chaos spontaneously develops in a regime, where the underlying local dynamics show stable limit cycle oscillations (diffusion-induced turbulence). We show that spatiotemporal chaos can be suppressed...

High-quality Si3N4 circuits as a platform for graphene-based nanophotonic devices.

Optics express

Gruhler N, Benz C, Jang H, Ahn JH, Danneau R, Pernice WH.
PMID: 24514740
Opt Express. 2013 Dec 16;21(25):31678-89. doi: 10.1364/OE.21.031678.

Hybrid circuits combining traditional nanophotonic components with carbon-based materials are emerging as a promising platform for optoelectronic devices. We demonstrate such circuits by integrating single-layer graphene films with silicon nitride waveguides as a new architecture for broadband optical operation....

[What kind of school do children need?].

Therapeutische Umschau. Revue therapeutique

Benz C, Largo R.
PMID: 22851458
Ther Umsch. 2012 Aug;69(8):447-51. doi: 10.1024/0040-5930/a000313.

At every age abilities mature and are internalized through corresponding experience. Every child wants to develop and learn, but at his own pace. In this process the child is not only active, but also selective, that is, it seeks...

Cross-diffusion in the two-variable Oregonator model.

Chaos (Woodbury, N.Y.)

Berenstein I, Beta C.
PMID: 24089955
Chaos. 2013 Sep;23(3):033119. doi: 10.1063/1.4816937.

We explore the effect of cross-diffusion on pattern formation in the two-variable Oregonator model of the Belousov-Zhabotinsky reaction. For high negative cross-diffusion of the activator (the activator being attracted towards regions of increased inhibitor concentration) we find, depending on...

Smooth excimer laser coronary angioplasty (SELCA) and conventional excimer laser angioplasty: Comparison of vascular injury and smooth muscle cell proliferation.

Lasers in medical science

Oberhoff M, Baumbach A, Herdeg C, Hassenstein S, Xie DY, Blessing E, Hanke H, Haase KK, Betz E, Karsch KR.
PMID: 20803272
Lasers Med Sci. 1997 Dec;12(4):328-35. doi: 10.1007/BF02767155.

Although the excimer laser, which utilizes 'non-thermal ablation effects', has achieved encouraging results in early clinical trials, the long-term results have failed to show any advantage over conventional percutaneous transluminal coronary angioplasty (PTCA).A new system, Smooth Excimer Laser Coronary...
