Further XPS and STEM-EDS analyses show that Tl isotope fractionation conforms to the Rayleigh fractionation model, and adsorption of 205 Tl onto hematite (Fe 2 O 3) may play an important role in the enrichment of the heavier Tl isotope. The findings demonstrate that Tl isotope analysis is a robust tool to aid our understanding of Tl …

Whereas a review of the fractionation of edible oils and fats in the 1980s (Hamm 1986) questioned to what extent solvents were necessary, a later review by the same author (Hamm 1995) concludes that the dry fractionation process has been so greatly improved that it has superseded the detergent and solvent fractionation …
The particle size of wheat flour has a significant effect on its functional properties. Three fractions of roller milled wheat flour were obtained using sieving: a coarse fraction (CF) with d 50 > 200 μm, a middle fraction (MF) with 100 μm < d 50 < 200 μm and a fine fraction (FF) with d 50 < 100 μm. An extra fine fraction was received by pulverizing …
Thanks to the fiber fractionation, the LF has a higher fiber accessibility, thus facilitating the mass transfer and reaction efficiency during the DES (ChCl-OA) treatment. Moreover, the DES treatment further improves the properties of LF in terms of purity (from 88.9 % to 95.1 %) and reactivity (from 43.0 % to 94.6 %).
In summary, high quality bamboo dissolving pulp is produced in a process consisting of a fractionation step, and a purification step (acid hydrolysis and CCE treatments). 3.5. Mill trials. Mill trials on the fractionation of the Kraft bamboo pulp and post purification treatment of the long-fiber fraction were conducted.

While chemical pulp mills require less external energy than mechanical pulps, these mills require about 2.2 tonnes of wood to manufacture one tonne of bleached kraft paper [116]. Since kraft mills manufacture most products from the PPI, they are responsible for 90% of CO 2 biogenic emissions and 80% of all emissions emerging from the PPI [ …

The results show that % 5 and% 10 tannery sludge compost amendment enhances the plant growth at the rate of 29-32%. The transfer coefficients for the metals in the decreasing order are as follows: Zn>Cu>Ni>Cr. It is found that the chemical distribution of the metals is directly related to the metals' soil-plant transfer.
