Examining the behaviour of dense suspensions has proven to be difficult, both experimentally and numerically. Using super water–absorbent polymer, PIV measurement was successfully conducted in a hydrogel suspension with volume fraction (VF) Φ =20% (see Zhang Rival, 2018). However, due slightly refractive index mismatch, image quality will degrade significantly as particle loading is increased. ...
In this work, we present a novel ex situ modification of bacterial cellulose (BC) polymer, that significantly improves its ability to absorb water after drying. The method involves single inexpensive and easy-to-perform process BC crosslinking, using citric acid along with catalysts, such as disodium phosphate, sodium bicarbonate, ammonium bicarbonate or their mixtures. particular, the mixture ...
Isolation of new Stenotrophomonas bacteriophages and genomic characterization of temperate phage S1.
Twenty-two phages that infect Stenotrophomonas species were isolated through sewage enrichment and prophage induction. Of them, S1, S3, and S4 were selected due to their wide host ranges compared to those of the other phages. S1 and S4 are temperate siphoviruses, while S3 is a virulent myovirus. The genomes of S3 and S4, about 33 and 200 kb, were resistant to restriction digestion. The lytic cy...
Polypropylene hollow fiber membrane (PPHFM) contactor, with aqueous solution absorbent such as sodium hydroxide (NaOH), monoethanolamine (MEA) and diethanolamine (DEA), was designed and used to separate and fix CO2 from CO2/N2 gas mixtures. The factors that influence the separation properties of CO2/N2 were investigated. It was found that the CO2 removal efficiency is the best by using MEA solu...
