Excimer laser crystallization is used to produce layered nanocrystalline silicon from hydrogenated amorphous silicon, using a partial melting process. Three types of hydrogenated amorphous silicon samples, 100, 300, and 500 nm thick, were laser treated in order to investigate the changes to the structural, optical, and electrical properties as a function of amorphous silicon thickness with exci...

BACKGROUND The treatment of inverse psoriasis can be both challenging and frustrating. Conventional topical and systemic treatments can be limited in terms of efficacy, acceptability and safety. The 308 nm excimer laser has been shown to be effective in the treatment of psoriatic plaques. METHODS A patient with chronic inverse psoriasis was treated with 308 nm excimer laser using a 3.5 cm spo...

A new class of molecular beacons were developed in which pyrene fluorophores were connected both at 3' and 5' ends of a single-stranded oligonucleotide. The two pyrene-based fluorophores were synthesized from the same starting material, so that the preparation of the beacons was simplified. The detection strategy of the beacons for target DNAs is based on "excimer-monomer emission switching" of...

Anti-tumor necrosis factor (TNF)-α antibody is utilized in the treatment of a variety of chronic inflammatory conditions, including psoriasis. However, it can induce paradoxical development and/or exacerbation of psoriasis in the course of anti-TNF-α antibody treatment, which is sometimes refractory to conventional treatments. Herein, we report a case of refractory palmoplantar pustular psorias...

This article describes the preparation of pyrene confined mesostructured silica nanoparticles for the trace detection of trinitrotoluene (TNT) in the aqueous phase. Pyrene confined mesostructured silica nanoparticles were prepared using a facile one-pot method where pyrene molecules were first encapsulated in the hydrophobic parts of cetyltrimethylammonium micelles and then silica polymerized a...

The improvements in excimer laser technology made hyperopic excimer refractive surgery a valuable option for hyperopia correction. However, despite the good visual and refractive outcomes of excimer laser photorefractive keratectomy (PRK) and laser in situ Keratomileusis (LASIK) treatments, they are more effective and stable for the correction of low degrees of hyperopia than high hyperopia1-7....

The X-ray structurally characterized naphthalene appended diformyl-p-cresol derivative () selectively detects Sn(2+) by both colorimetric and fluorescence methods. In the presence of Sn(2+), exhibits a monomer emission at 420 nm along with a strong red excimer emission at 582 nm in acetonitrile. The excimer formation highly depends on Sn(2+) concentration. The dynamic excimer, observed with up ...

High astigmatism correction represents a challenge for the refractive surgeon with current available technology. Excimer laser correction should be considered as an option in the available therapeutic arsenal. We report a patient with astigmatism higher than eight diopters to whom it was used a treatment with LASIK (Laser Assisted In Situ Keratomileusis) in two surgical moments, using a new gen...
