Evidence of the interaction of evaporated Pt nanoparticles with variously treated surfaces of highly oriented pyrolytic graphite.

The journal of physical chemistry. B

Yang DQ, Zhang GX, Sacher E, José-Yacaman M, Elizondo N.
PMID: 16623519
J Phys Chem B. 2006 Apr 27;110(16):8348-56. doi: 10.1021/jp060513d.

The interactions of Pt nanoparticles, deposited by evaporation onto highly oriented pyrolytic graphite surfaces modified by kiloelectronvolt Ar+ beam treatment, have been studied by X-ray photoelectron spectroscopy core-level line shape analysis. The C1s and Pt4f7/2 peaks were each considered...

Recognizing the Emergence of Man: Specific courses of action are necessary for identifying the traces of early man.

Science (New York, N.Y.)

Ascher R, Ascher M.
PMID: 17788202
Science. 1965 Jan 15;147(3655):243-50. doi: 10.1126/science.147.3655.243.

Recognition of early human industries takes on significance with the realization that commitment to tools is the novel adaptive design accounting for the emergence of man. The most abundant evidence for the emergence of man consists of the stones...

Mode locking using a type II multiple-quantum-well structure as a fast saturable absorber.

Optics letters

Feldmann J, Sacher J, Göbel E.
PMID: 19773895
Opt Lett. 1991 Feb 15;16(4):241-3. doi: 10.1364/ol.16.000241.

We demonstrate the application of a type II Al(x)Ga((1-x))As/AlAs multiple quantum well as a fast saturable absorber in a hybridly mode-locked dye laser. Type II multiple quantum wells are promising for this application because of the fast recovery of...

Functionalization of multiwalled carbon nanotubes by mild aqueous sonication.

The journal of physical chemistry. B

Yang DQ, Rochette JF, Sacher E.
PMID: 16851905
J Phys Chem B. 2005 Apr 28;109(16):7788-94. doi: 10.1021/jp045147h.

Sonication has been widely used in the dispersal of carbon nanotubes (CNTs) in various liquids as well as in their functionalization in aqueous acids. Here, for the first time, we study the sonication of multiwalled CNTs (MWCNTs) in deionized...

Dopamine Receptor Activation Is Required for GABAergic Spike Timing-Dependent Plasticity in Response to Complex Spike Pairing in the Ventral Tegmental Area.

Frontiers in synaptic neuroscience

Langlois LD, Dacher M, Nugent FS.
PMID: 30297996
Front Synaptic Neurosci. 2018 Sep 21;10:32. doi: 10.3389/fnsyn.2018.00032. eCollection 2018.

One of the most influential synaptic learning rules explored in the past decades is activity dependent spike-timing-dependent plasticity (STDP). In STDP, synapses are either potentiated or depressed based on the order of pre- and postsynaptic neuronal activation within narrow,...

A Model for Human Islet Transplantation to Immunodeficient Streptozotocin-Induced Diabetic Mice.

Cell transplantation

Estil Les E, Téllez N, Nacher M, Montanya E.
PMID: 30269527
Cell Transplant. 2018 Nov;27(11):1684-1691. doi: 10.1177/0963689718801006. Epub 2018 Oct 01.

Streptozotocin (STZ) is a cytotoxic glucose analogue that causes beta cell death and is widely used to induce experimental diabetes in rodents. The sensitivity of beta cells to STZ is species-specific and human beta cells are resistant to STZ....

Effects of Ability and Effort Praise on Children's Failure Attribution, Self-Handicapping, and Performance.

Frontiers in psychology

Xing S, Gao X, Jiang Y, Archer M, Liu X.
PMID: 30333782
Front Psychol. 2018 Oct 02;9:1883. doi: 10.3389/fpsyg.2018.01883. eCollection 2018.

Previous research has suggested that children praised for ability are more likely to attribute their failure to low ability compared to those who are praised for effort. At the same time, self-worth theory suggests that when an individual's self-worth...

Ventricular Tachycardia Isthmus Characteristics: Insights from High-density Mapping.

Arrhythmia & electrophysiology review

Martin R, Hocini M, Haïsaguerre M, Jaïs P, Sacher F.
PMID: 30918668
Arrhythm Electrophysiol Rev. 2019 Mar;8(1):54-59. doi: 10.15420/aer.2018.78.2.

In the context of structural heart disease, ventricular tachycardia (VT) is related to surviving fibres in incomplete scar. New technologies which allow electroanatomic mapping at higher density and with smaller, more closely spaced electrodes have allowed new insights into...

OBJECTIVES: The aim of this study was to describe the epidemiology of infantile Pompe disease (IPD) in French Guiana, a French overseas territory, by combining a retrospective case records study and a prospective anonymous genotyping in a sample of...
