Scientific reports, 5, 16761-16761 (2015-11-17)
The advent of flexible optoelectronic devices has accelerated the development of semiconducting polymeric materials. We seek to replace conventional expensive semiconducting photodetector materials with our cost-effective composite system. We demonstrate in this work the successful fabrication of a photoconductive composite

The Journal of otolaryngology, 29(2), 78-82 (2000-05-20)
There are two lasers for resurfacing. The erbium:YAG laser and the CO2 laser both have different physical and physiologic differences when striking the skin. Therefore, each laser gives a different result. This article reviews the use of the Sharplan Silktouch

Carbohydrate polymers, 121, 302-308 (2015-02-11)
In this study, chitosan functionalized LaF3:Yb,Er upconverting nanotransducers (UCNTs) with controlled size and shape have been successfully synthesized by a facile one pot precipitation method. The chitosan encapsulated UCNTs show bright upconversion fluorescence upon excitation with 974 nm NIR region.

International journal of biological macromolecules, 72, 1308-1312 (2014-12-03)
In this work, we described one pot hydrothermal synthesis of surface modified water soluble YF3: Yb, Er upconverting nanofluorophores (UCNFs) using natural biopolymer chitosan. The obtained nanocrystals have undergone X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy
