Analysis of Surface Yellowing of a Drug Tablet upon Light Exposure Using Time of Flight Secondary Io
Time of flight secondary ion mass spectrometry (ToF SIMS) was used to determine the cause of a surface yellowing of a drug tablet when exposed to light. The technqiue was able to determine the nature of the yellow material and hence lead to a an understanding of the cause.

Facile Synthesis of Electroluminescence Acridinedions by Microwave and Ultrasound
Various highly fluorescent acridinediones were synthesized by microwave, ultrasound irradiations, and conventional thermal methods. It was found that most of the acridinedione derivatives could be obtained in very high yields using microwave-assisted, solvent-free, one-pot synthesis process within
