Abstract—For traditional painting materials, the artisan used to combine the pigments with different binders to create colors. As time goes by, the materials used for painting evolved from natural to chemical materials. The vast variety of ingredients used in chemical materials has complicated restoration work; it makes conservation work more difficult. Conservation work also becomes harder whe...
Mycobacterium bovis is the causative agent of bovine tuberculosis. Various genetic typing techniques have been used to trace the reservoirs of infection; however, they have limited success in population genetics and outbreak studies. Fourier-transform infrared spectroscopy (FT-IR) is a rapid phenotypic typing technique, which may be used to generate a metabolic fingerprinting and is increasingl...
Microbiological safety plays a very significant part in the quality control of milk and dairy products worldwide. Current methods used in the detection and enumeration of spoilage bacteria in pasteurized milk in the dairy industry, although accurate and sensitive, are time-consuming. FT-IR spectroscopy is a metabolic fingerprinting technique that can potentially be used to deliver results with ...
One-step mid- and far-Fourier-transform (FT)-IR spectroscopy is a facile powerful tool that provides various information regarding chemical crystal states. However, its potentially high applicability has not been sufficiently demonstrated. In the present study, ibuprofen (IB)-loaded MgO samples are prepared via different methods, they evaluated using scanning electron microscopy (SEM), thermogr...
This review compares and contrasts MALDI-MS, FT-IR spectroscopy Raman for whole organism fingerprinting bacterial typing.
this research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (pvb) based on weight loss analysis and non-isothermal approaches. the weight loss by the un-irradiated pvb upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...
background: n-acyl homoserine lactone (ahl) is found to be the main component of quorum sensing (qs) in gram-negative bacteria and plays an important role in biofilm formation. little information is available regarding the role of ahl in biofilm formation in escherichia coli (e. coli). the purpose of this investigation was to biochemically detect and characterize ahl activity in biofilm-forming...
The authenticity of milk and milk products is important and has extended health, cultural, and financial implications. Current analytical methods for the detection of milk adulteration are slow, laborious, and therefore impractical for use in routine milk screening by the dairy industry. Fourier transform infrared (FT-IR) spectroscopy is a rapid biochemical fingerprinting technique that could b...
This synopsis of FT-IR spectroscopic applications in waste management covers relevant issues regarding monitoring, process and quality control. Quality in this context means low reactivity, low gas forming potential and compliance with limit values of materials to be landfilled, appropriate compost ingredients and improvement of the stable carbon pool by humification of compost organic matter. ...
Zinc borate is an important boron compound that can be used as multi-functional flame retardant additive due to its high dehydration temperature property. In this study, the raw materials of ZnSO4.7H2O, NaOH and H3BO3 were characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR) and used in the synthesis of zinc borates. The synthesis parameters were set to 1...
