“…Newton, the founder of classical mechanics, split sunlight using glass prisms in the seventeenth century (Newton, 1672). Coming to the twentieth century, numerous scientists such as Å ngström, Beer, and Einstein eventually established light as quantum mechanics based on further research (Thomas, 1991). UV, which means beyond violet, is subdivided into UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (200-280 nm) (Maverakis et al, 2010).…”

The production of soybean continues to increase worldwide. People are showing more interest in the beneficial health effects of soybeans than before. However, the origin and history of soybeans are still being discussed among many researchers. Chromatographic methods enable the desirable separation of a variety of isoflavones from soybeans. The structures of isolated soy isoflavones have been successfully identified in tandem with spectroscopic analytical instruments and technologies such as liquid chromatography, mass spectrometry, and nuclear magnetic resonance spectroscopy. The theoretical background behind spectroscopy may help improve the understanding for the analysis of isoflavones in soybeans and soy-derived foods. This review covers the origin of the English name of soybean and its scientific name, Glycine max (L.) Merrill, based on the evidence reported to date. Moreover, the reports of soy isoflavones discovered over a period of about 100 years have been briefly reviewed.

“…The infrared (IR) region, found between the visible and microwave region of the electromagnetic spectrum, was first discovered by Herschel in 1800 (Cozzolino, 2009). The potential application of IR energy in chemical analysis was, however, only realised in 1882 by Abney and Festing, who correlated the absorption of certain wavelengths of light in this region to the presence of certain organic compounds (Thomas, 1991). Thus, an inference of the chemical composition of a particular substance/matrix can be made due to the vibrations (i.e.…”

Unravelling the complexities of wine: A big data approach to yeast assimilable nitrogen

Aim: Assimilable Nitrogen (YAN) has been identified as one of the main drivers of wine quality, influencing the production of various aromas and ensuring a successful fermentation to dryness. Due to the number of factors affecting YAN concentration and composition, paired with the complexities of yeast metabolism, more data is required to enable a comprehensive understanding of this important component of the grape juice matrix. The use of high throughput and information-rich techniques such as InfraRed spectroscopy can lead to a fast generation of a large amount of data. In addition, there is a possibility to maximise the information output of the generated data when combined with various descriptive and exploratory statistical techniques.Conclusion: Given the recent developments in the fields of analytical equipment and chemometrics, the review explores the possibility of a Big Data approach for the research of one of the most important and versatile grape juice parameters, namely YAN

The notable nowadays physical-chemical structures as ionic liquids (ILs) are, due to their versatility properties adjusted by changing either the anion or cation sides, with spread applications as solvents (viz. organic reaction, bio-and nano-catalysis, polymerization), electrolytes (viz. fuel cells, batteries and sensors), lubricants and additives (including fuel additives), or in chemical engineering including separation (gas chromatography/GC-head space solvents, gas separation, membranes extraction, extractive distillation), heat storage (as thermal fluids), till the nano-technology (protein crystallization, liquids crystals and their use in monitor displays, robotics and artificial muscles), just to name few, are in the present chapter reviewed from the scientific generations created with their structural consequences; they are then used as the compounds for which the recently predicted bondon as the quantum quasi-particle of chemical bonding may be identified in the allied Raman/IR spectra through a specific algorithm involving the bondonic quantum numbers prediction in spectra and of their most tangible quantum appearance; this because the invariable four-levels for bondonic formations confirms the quantum entangled states associated with their existences, as just noted by Putz and Ori (2015), see Chap. 10 of the same monograph, while the objective realization associates either with IR or Raman of IL computed spectra; connection with experimental recorded IR spectra is also presented with encouragement perspective for bondonic observation, while correlation with eco-toxicological data (EC50) is equally presented and interpreted from a bondonic sub-atomic perspective.
