The present work describes a laboratory terahertz (THz) imaging spectroscopy system and its possibilities to inspect solid dosage forms in the form of coated tablets and capsules. Moreover, the chemical composition and layer structure of coated pharmaceutical tablets are investigated. These chemical and physical properties of solid dosage forms can be used for the detection of counterfeit drugs. Preliminary results show that THz time domain spectroscopy and imaging is a promising technology for

This paper presents an optimization of a single cell electrical model, based on Maxwell’s mixture Theory, applied to flow cytometry coupled to impedance spectroscopy. It is based on the discretization of the measurement area into a square reference volume, centered between micro-electrodes, and fixed impedance areas. The first one represents the sensing area, the one impacted by cell presence during measurement, and the second one, all other areas that contribute to global measured impedance

Microwave spectroscopy have been applied in numerous applications in the non-food industry, and recently also in the food industry, for non-destructive measurements. In this study, a dry-cured ham model was designed and water activity, water content and salt content (sodium chloride) were determined for all samples using chemical analysis. The water activity was also measured using microwave spectroscopy, with a rectangular microwave cavity resonator. Attained results indicate that microwave

In this paper, composition analysis using scanning electron microscopy/energy-dispersive X-ray spectroscopy analysis (SEM-EDX) and laser-induced breakdown spectroscopy (LIBS) for particulate matter in diesel exhaust is presented. Conventionally, scanning mobility particle sizer (SMPS) has been widely used to obtain particle size distribution of the suspended particles. However, real-time analysis of the composition of diesel particulate matter is difficult because of the small sized particles

The study is focused on the analysis of the diffusing-wave-spectroscopy signal recorded invivo on the ocular fundus of a rabbit eye. The motion of the scattered sites was measured as a function of the pressure exerted by a Goldmann contact lens and during the moderate temperature increase induced by a therapeutic laser diode. Temporal fluctuations of the signal revel motion of molecules and thus changes in tissues temperature and chorioretinal blood velocity. Experimental results show the
