Conformational and Structural Determinations of Substituted Four and Five Membered Rings by Infrared, Raman, and Microwave Spectral Studies
Studies of the structure and conformational stabilities of molecules have become increasingly important due in part to advances in the fields of biochemistry and nanochemistry. Specifically the conformation of organoamines is currently at work in every human alive with this arising from the amino …

Development of In Situ Monitoring and Data-Driven Modeling for Complex Systems: Case Study on Simulant Mixtures of Nuclear Waste
Approximately 90 million gallons of nuclear and chemical waste are stored at the Hanford and Savannah River Sites in the United States. One of the main challenges associated with nuclear waste treatment and stabilization is the complexity of the waste, which calls for extensive sampling during …

Rapid pre-symptomatic diagnosis of sepsis by vibrational spectroscopy
… dysfunction. Each year, over 30 million cases and 5 million deaths are estimated worldwide. Diagnosis of sepsis is based on non-specific clinical signs and time consuming positive identification of the causative pathogen(s). Rapid presymptomatic detection of sepsis would enable the early …

Drug-Polymer and Drug-Lipid Miscibility for the Development of Amorphous Solid Dispersions and Solid Lipid Nanoparticles
… carcinoma. FLT amorphous solid dispersions (SDs) and solid lipid nanoparticles (SLNs) were prepared to overcome limited solubility. Investigation of drug-polymer and drug-lipid miscibility was carried out to enhance drug performance by assessing solubility and particle size. Miscibility was then …

The synthesis and characterisation of halogen and nitro phenyl azide derivatives as highly energetic materials
… azide was synthesised as previously described and fully characterised using Infrared and Raman spectroscopy, elemental analysis, NMR spectroscopy (1H, 13C, 14N) and X-ray structural analysis. 2,4,6-tribromophenyl azide was recrystallised from ethanol to give pink needles which are monoclinic, …

Practical Applications of Infrared, Raman and Nuclear Magnetic Resonance Spectroscopic Techniques for Qualitative, Quantitative and Structural Analysis of Pharmaceutical Drugs, Cementitious Material and Organic Molecules Containing Phosphorous
The study of the interaction between matter and electromagnetic radiation which procreated the wide branch named as Spectroscopy has gained tremendous attention since the last century. Atoms and molecules respond to electromagnetic radiation to produce their unique spectra which can be used to …
