21. Applications of near-infrared spectroscopy in process analytical chemistry
Sammanfattning : .... LÄS MER
22. Near-infrared gas analysis spectroscopy systems with semiconductor lasers
Sammanfattning : .... LÄS MER
23. Nanosecond tandem optical parametric oscillators for mid-infrared generation
Sammanfattning : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. LÄS MER
24. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis
Sammanfattning : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. LÄS MER
25. Synthesis of Conjugated Polymers and Small Molecules for Organic Light-Emitting Devices and Photodetectors
Sammanfattning : Production cost and environmental impact are the two major concerns that are related to the conventional optoelectronic devices. It is desirable for the modern semiconductors that they are free of toxic/costly metals, they can be processed with low-cost solution-based methods, and their optical, electronic, and mechanical properties can be easily tuned depending on the target application.
