The non-Hermitian skin effect is a phenomenon in which an extensive number of states accumulates at the boundaries of a system. It has been associated to nontrivial topology, with nonzero bulk invariants predicting its appearance and its position in

Biochemical Investigation of Some Proteins from Human Primary Teeth to Evaluate Heavy Metal Pollution

Autor: D. Iordǎchescu, Cristina M. Ciofrangeanu, Bianca Galateanu, Stef Manea, Anisoara Cimpean, R. Ciubar Ion

Publikováno v: Key Engineering Materials. 415:53-56

This investigation is based on the premise that heavy metals are sequestered by the mineral phase of teeth [1,2], hydroxyapatite, during their formation and there is a relation between heavy metal pollution and progressive destruction of human primar

TPPS4 Controlled Release from PVA Hydrogels in Photodynamic Therapy of Cancer

Autor: S. C. F. Patachia, R. M. Ion

Publikováno v: International Conference on Advancements of Medicine and Health Care through Technology; 5th – 7th June 2014, Cluj-Napoca, Romania ISBN: 9783319076522

Hydrogels are hydrophilic polymer networks whose applications are based on their ability to retain large amounts of water. They can be used as drug carriers structures with applications in the controlled release of active substance. In this paper, th

Characterising polymer surfaces—nanoindentation, surface force data, calorimetric microscopy

Autor: Hubert M. Pollock, N S Lawson, M. Reading, Douglas J. Hourston, R H Ion

Publikováno v: Physica Scripta. :199-205

Techniques now exist that allow near-surface mechanical and thermal properties of polymers to be measured at very high depth resolution. We review the use of: nanoindentation (hardness, modulus, flow properties, profilometry); force spectroscopy (adh

Micron-scale indentation of amorphous and drawn PET surfaces

Autor: H. M. Pollock, C. Roques-Carmes, R. H. Ion

Publikováno v: Journal of Materials Science. 25:1444-1454

The plastic, elastic and flow properties of the near-surface region of poly(ethylene terephthalate), either amorphous or uniaxially drawn, are measured by means of a sub-microindentation technique with continuous depth recording. The depths investiga
