Effects of molecular weight of polyacrylamide (PAM), concentration of NaClO and reaction temperature on formation of amino and carboxyl groups during the Hofmann reaction of PAM with high molecular weights were investigated. The amino, carboxyl, and isocyanic groups formed during the reaction were ...
Up to date, this is the largest data bank investigated for isobaric heat capacities of DESs in the open literature. Based on this database, a simple, straightforward, yet precise correlation was developed to estimate the heat capacities of DESs as a function of temperature, molecular weight, ...
The information about their interaction with UO 2(II) ions in an aqueous solution (100 mg l 1 of fulvic acid, in 0.1 M NaClO 4 at pH 3.5) was obtained from the measurement of SyF spectra at increasing concentrations of metal ions. Self-modeling mixture analysis of the quenching spectra ...
Microalgae are a renewable and promising biomass for large-scale biofuel, food and nutrient production. However, their efficient exploitation depends on our knowledge of the cell wall composition and organization as it can limit access to high-value mole
software. Cellulose crystallinity was determined using both the relative band heights of 1,429/897 cm−1 (Akerholm et al. 2004) and relative band areas of 1,375/2,900 cm−1 (Nelson and O’Connor 1964a, b). For molecular weight analysis of cellulose, extractive-free wood (Osman et ...
Fifty tomato seeds of uniform size were surface sterilized with 0.5% NaClO (Xilong Scientific Co., Ltd., China), for 5 min and washed five times with sterile water. Ten seeds were transferred to Petri plates covered with a layer of cotton and filter paper. A spore suspension of theTrichode...
Seeds of twoBrassica napusL. cultivars [Zheda 622 (ZD 622) and ZS 758] were kindly provided by the College of Agriculture and Biotechnology, Zhejiang University. Healthy and uniform seeds were surface-sterilized in 0.1% NaClO for 15 min, and then the seeds were rinsed for 20 min with...
The seeds were washed, sterilized with 5.5% sodium hypochlorite (NaClO) for 1min, then washed with ddH2O for three times and were kept in ddH2O for 24 h for germination initiation. To make the bacterial solution, a fresh culture of bacteria was centrifuged, and the pellets were washed by...
The seeds of rapeseed (Zhongshuang 11) were sterilized with NaClO and cultured in 0.5 mM CaCl2 for 6 days. After germination, the uniform seedlings were transferred to a modified Afdaling’s nutrition solution for 6 days. The modified solution had the following nutrient concentrations: 3 mM ...
Cl2+2NaOH→NaCl+NaClO+H2O Cl2+H2O→HCl+HClO The proposed process differs from conventional chlorination reactions in the course of polymeranalogic transformation in that, in case of the presence of chloroxygen-containing compounds, the main role in the modification process is played by oxygen, not...
