Itraconazole is a triazole antifungal agent that is synthesised. Itraconazole has been manufactured into a variety of pharmacological formulations and administered in a variety of ways. Itraconazole pills are used to treat pulmonary fungi that can cause fungal infection and spread throughout the body. Because Itraconazole is not yet officially listed in any pharmacopoeia, only a few procedures for quality control and stability testing in pharmaceutical formulations have been published.

For the gold nanosandwiches, also an infrared ellipsometric measurement is done. For complex layers like these, advanced modeling is necessary.

The aim of this project was to assess the feasibility of using UV spectroscopy for a simple detection system for formaldehyde gas in the indoor environment. Formaldehyde gas is hazardous to human health causing irritation of the eyes, nose and throat, headaches, limited pulmonary function and is a potential carcinogen. Formaldehyde derivatives are used in plywood and fibre board, carpeting, fabrics and some paints. The gas can be emitted from these materials and can build up in the indoor environment. Current methods for detecting formaldehyde gas that are simple, reliable and inexpensive are

The charge transport properties of these polymeric materials have been studied in detail because of their potential application in gas sensors.

Abstract Weathering exposure tests were performed on unscribed panels painted with organic coating systems consisting of various aerospace primers and pretreatments and a single topcoat (MIL-PRF-85285C). Electrochemical Impedance Spectroscopy (EIS) was used to measure the electrical properties of these exposed and unexposed coating systems at various time intervals. The relationship between the chromate leach rate for these different coating systems and the current coating system barrier properties was examined previously [1].

Polymers are susceptible to altered chemistry from UV radiation. The absorption of UV photons can promote breakage of important functional groups and structural bonds, such as C=C and C=O [1]. When an organic molecule absorbs UV radiation, it will be excited into higher energy states and possibly dissociate bonds. Dissociated radical species can then participate in additional reactions. Changes in chemistry may affect optical properties, which can have serious effects for polymers used in optical systems.
