Abstract

The photodegradation of the films was investigated quantitatively by measuring the photoluminescence (PL) efficiency as a function of the irradiation time and temperature for various intensities. Comparison of the degradation of the glass films in air and in an Ar atmosphere revealed that the main mechanism of photodegradation of the green-emitting nanocrystals (NCs) was oxidization from the first electronically excited state.

Abstract

Background: Intestinal transplantation provokes an intense inflammatory response within the graft muscularis that causes intestinal ileus. We hypothesised that endogenously produced anti-inflammatory substances could be utilised as novel therapeutics. Therefore, [...]

32. Fluorescence and EPR characteristics of Mn2+-doped ZnS nanocrystals prepared by aqueous colloidal method

Abstract

Research was conducted to examine the fluorescence characteristics of Mn:ZnS crystallites using electron paramagnetic resonance spectroscopy. The samples had an average diameter of 4 mn and were prepared using an aqueous colloidal technique under 266 nm light excitation. Results revealed that Mn:Zns nanocrystals prepared by the aqueous colloidal technique did not demonstrate lifetime shortening effect in the Mn2+ emission arising from quantum confinement.

34. Melt-quenched KCl:Eu2+ films for photostimulated luminescence applications

Author

Abstract

A conventional melt-quenching technique was employed in the preparation of Eu2+-doped KCl films. The films exhibited strong photostimulated luminescence. Electron paramagnetic resonance spectrum also shows hyperfine structures caused by Eu2+ centers that disappear at low temperatures. This phenomenon is attributed to the development of complexes induced by defect center trapping at the Eu2+ sites.

50. Accessory scrotum with perineal lipoma diagnosed prenatally: case report and review of the literature

Abstract

We report a case of accessory scrotum (AS) in the perineal region with peduncular lipoma, diagnosed prenatally. A male fetus of 31 weeks’ gestation was referred to our department with a perineal mass. Prenatal ultrasonography and magnetic resonance imaging showed a mass of 1.0 × 1.2 cm located posterior to the scrotum. No other abnormalities were noted during pregnancy. The patient was delivered vaginally at 38 weeks of gestation. On physical examination, a soft peduncular mass with a rugged and pigmented swelling was located between the normally developed scrotum and the anus. There were no specific symptoms or any other associated congenital anomalies. We completely excised the mass at one month of age. A histological examination revealed lipoma, with tissue suggestive of scrotum, so a definite diagnosis of AS was made. AS is a rare congenital anomaly of the scrotum. We review the literature.
