Radiative properties of silicon related materials
… of silicon, as a function of temperature, in the infrared range of wavelengths. The wavelength range, considered in this study, is between 1 micron and 20 microns. The temperature range observed is from 50 degrees Celsius to 1000 degrees Celsius. Varying wafer thickness and doping are taken into …

Electro-optical method of distinguishing recyclable plastics
… be and cannot be recycled with the help of an infrared spectrometer. Different types of plastics (e.g., PVC, PET, HDPE) have different forms of spectra. Materials can be identified by comparing their spectra to reference spectra. The aim here is to make a cheap and simple device to do this in …

Vibrational dynamics of aqueous hydroxide solutions studied using ultrafast infrared spectroscopy
… ions. In this thesis, we have employed ultrafast infrared spectroscopy in conjunction with theoretical modeling to understand the nature of the vibrations and their dynamics in aqueous hydroxide solutions. The infrared spectra of aqueous solutions of NaOH and other strong bases exhibit a broad …

Surface-Enhanced Spectroelectrochemistry using Synchrotron Infrared Radiation
… to perform surface-sensitive, time-resolved infrared measurements in the milli- to microsecond regime. I will make the case that an infrared spectroelectrochemical technique, namely attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS), is applicable …

Stimuli-responsive self-assembling materials comprising amphiphilic copolymers for localized remotely triggered therapeutic delivery
… copolymer micellar aggregates for near-infrared responsive enhanced therapeutic delivery. It was discovered that the films released small-molecule non-steroidal anti-inflammatory drug diclofenac up to five-fold faster during remote irradiation with near-infrared. The near-infrared source …

Development of microcantilever mid-infrared detectors and sources and their application in infrared spectroscopy
Mid-infrared (mid-IR) light is an electromagnetic radiation with the wavelengths of 3 – 30 um. This spectral range includes the dominant wavelengths of the thermal radiation emitted by objects at or near room temperature, and vibrational and rotational resonance frequencies of many molecules. The …
