Development and Application of Laboratory X-ray Fluorescence Holography Equipment

The X-ray fluorescence holography (XFH) method has drawn the attention of many researchers as a novel experimental technique for imaging a three-dimensional local atomic structure around a certain element in a single crystal. Synchrotron radiation (SR) has been mainly used for the measurements because of extremely weak signals which are about 0.3 % of isotropic fluorescent radiation. The measur...

Preservatives in liquid pharmaceutical preparations.

Sodium benzoate, potassium sorbate, and methyl hydroxybenzoate are commonly used as preservatives in liquid pharmaceutical preparations. The purpose of this study is to determine the amount of the aforementioned preservatives in pharmaceutical products, as some recent studies have reported serious side effects associated with the ingestion of these substances. The content of 37 liquid pharmaceu...
