A rapid method for methanol quantification in spirits using UV-visible spectroscopy and FTIR [PDF]

PeerJ Analytical Chemistry
Although standards methods of food safety assessment are important, these methods are relatively expensive and require intensive work and time. In alcohol beverage industries, ultraviolet visible (UV-Vis) spectroscopy and Fourier transform infrared (FTIR)

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Detection of Honey Adulteration Using UV–Vis Absorption Spectroscopy and Chemometrics

Foods
This preliminary study demonstrates the use of ultraviolet–visible (UV–vis) absorption spectroscopy coupled with chemometric modeling to detect and quantify honey adulteration. UV–vis spectra of pure honey and samples experimentally adulterated with corn,

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Control of the molecular density in a chemically adsorbed thiophene system monolayer

MATEC Web of Conferences, 2013
Chemically absorbed monolayers (CAM) of thienyl functionalized n-alkyltrichlorosilane 11-(3-thienyl) undecyltrichlorosilane (TUTS) have been prepared with two methods which are the standard technique (TUTS-STD) and the twice adsorption method (TUTS-TAM).
