J Phys Chem A. 2015 Sep 03;119(35):9363-72. doi: 10.1021/acs.jpca.5b05409. Epub 2015 Aug 25.

The relationship between equatorial ligands structures and magnetic response of [Ni3]6+ extended metal atom chain core has been investigated. The distances between metal ions in Ni metal strings are largely predefined by framework provided through equatorial ligands. The equatorial...

On reversible bonding of hydrogen molecules on platinum clusters.

PMID: 19256601
J Chem Phys. 2009 Feb 28;130(8):084111. doi: 10.1063/1.3072369.

The local reactivity of hydrogenated platinum clusters (Pt clusters) has been studied using the regional density functional theory method. We observed that antibond orbitals constitute the preferable binding site for hydrogen molecules H(2). Those sites are characterized by lowered...

Modulation spectroscopy study of the effects of growth interruptions on the interfaces of GaAsSb/GaAs multiple quantum wells.

The effects of growth interruption times combined with Sb exposure of GaAsSb/GaAs multiple quantum wells (MQWs) have been investigated by using phototransmittance (PT), contactless electroreflectance (CER) and wavelength modulated surface photovoltage spectroscopy (WMSPS). The features originated from different portions...

Synthesis and characterization of polysaccharide-maghemite composite nanoparticles and their antibacterial properties.

Nanoscale research letters

Iconaru SL, Prodan AM, Motelica-Heino M, Sizaret S, Predoi D.
PMID: 23088756
Nanoscale Res Lett. 2012 Oct 22;7(1):576. doi: 10.1186/1556-276X-7-576.

The aim of this study was to obtain saccharide (dextran and sucrose)-coated maghemite nanoparticles with antibacterial activity. The polysaccharide-coated maghemite nanoparticles were synthesized by an adapted coprecipitation method. X-ray diffraction (XRD) studies demonstrate that the obtained polysaccharide-coated maghemite nanoparticles...

Curcumin modulates airway remodelling-contributing genes-the significance of transcription factors.

Journal of cellular and molecular medicine

Despite considerable efforts, the properties that drive the cytotoxicity of engineered nanomaterials (ENMs) remain poorly understood. Here, the authors inverstigate a panel of 31 ENMs with different core chemistries and a variety of surface modifications using conventional in vitro...

Chitosan-coated electrospun nanofibers with antibacterial activity.

Journal of materials chemistry. B

Croisier F, Sibret P, Dupont-Gillain CC, Genet MJ, Detrembleur C, Jérôme C.
