Waterborne fluoropolymer emulsions were synthesized using the one-step semi-continuous seed emulsion polymerization of chlorotrifluoroethylene (CTFE), vinyl acetate (VAc), n-butyl acrylate (BA), Veova 10, and acrylic acid (AA). The main physical parameters of the polymer emulsions were tested and analyzed. Characteristics of the polymer films such as thermal stability, glass transition temperat...

We asked whether odor discrimination abilities are sexually dimorphic in mice and, if so, whether the perinatal actions of estradiol contribute to these sex differences. The ability to discriminate different types of urinary odors was compared in male and female wild-type (WT) subjects and in mice with a homozygous-null mutation of the estrogen synthetic enzyme, aromatase (aromatase knockout; A...

The question whether pyruvic acid holds a key position as an intermediate in the butanol-acetone fermentation by Clostridium acetobutylicum (Weizmann) similar to that in the alcoholic fermentation by yeast and in glycolysis by muscle has, so far, not received a decisive answer. This is mainly due to the inconsistent results obtained by different workers in this field. As in the case of corn-mea...

Background: Agaricus bisporus is an edible basidiomycete fungus. Both the body and the mycelium contain compounds comprising a wide range of antimicrobial molecules, contributing in improvement of immunity and tumor-retardation. Objectives: The presence of endophytes capable of producing bioactive compounds was investigated in Agaricus bisporus. Materials and Methods: Endophytes from Agaricus b...

Lignin-rich stream from lignocellulosic ethanol production was converted into biocrude by continuous hydrothermal liquefaction (HTL) while hydrogen produced aqueous phase reforming (APR) of the HTL by-product. The effects Na2CO3 and NaOH were investigated both in terms processability feedstock as well yield composition obtained products. A maximum 27 wt% reached NaOH-catalyzed runs. relevant am...

the feasibility of extractive reaction of methacrylic acid from aqueous solution using a quaternary amine, tri–octyl methyl ammonium chloride (tomac) as an extractant, was studied. the diluents chosen in the present work belong to different chemical classes, n–butyl acetate, carbon tetrachloride, isoamyl alcohol, methyl isobutyl ketone, and toluene. the effect of initial acid concentration in t...

This study shows the impact of three different commercial inactive yeast derivatives (IYDs) (Opti Less™, Noblesse™, Optimum White™, Lallemand, Canada and Oenolees MP™ Lafort, USA) during 6-month aging period on volatile profile, sensory attributes antiradical activity, including polyphenols total free sulfhydryl (-SH groups) content, Grašac wines made in sequential fermentation with native Hans...

Alcea nudiflora (Lindl.) Boiss. (Malvaceae) has a wide area of growth in Central Asia, the Altai territory and Western Siberia long been used folk traditional medicine. Availability resource long-term application practice makes promising source valuable biologically active natural compounds. The chemical composition A studied after effective microwave assisted extraction (MAE) performed using s...
