Influence of organic solvents on catalytic behaviors and cell morphology of whole-cell biocatalysts for synthesis of 5'-arabinocytosine laurate. [PDF]

open access: yesPLoS ONE, 2014
A whole-cell based method was developed for the regioselective synthesis of arabinocytosine laurate. Among the seven kinds of bacteria strains tested in the acylation reaction, Pseudomonas fluorescens gave the highest productivity and a higher 5 ...

Alternative green solvents in sample preparation

open access: yesGreen Analytical Chemistry, 2022
Sample treatment is one of the most contaminant steps in the analytical process, mainly due to the high consumption of energy and petrol-based organic solvents, which involve a high environmental impact. One of the most promising strategies to reduce the

A Simple, Quick, and Precise Procedure for the Determination of Water in Organic Solvents [PDF]

open access: yes, 1990
A procedure for the UV/VIS-spectroscopic determination of water by the use of a solvatochromic pyridiniumphenolate betaine is given. The water content of organic solvents is calculated by a two parameter equation from λmax of the dye.

Design and fabrication of chemically robust three-dimensional microfluidic valves [PDF]

open access: yes, 2007
A current problem in microfluidics is that poly(dimethylsiloxane) (PDMS), used to fabricate many microfluidic devices, is not compatible with most organic solvents. Fluorinated compounds are more chemically robust than PDMS but, historically, it has been
