an aquaculture system can be a potentially significant source of antibacterial compounds and ammonia in an aquatic environment. in this study, the removal of total ammonia nitrogen and florfenicol antibiotic from synthetic aqueous wastewater was assessed by applying a commercial tfc (thin film composite) polyamide nanofilter. the effects of ph (6.5-8.5), pressure (4-10 bar), concentration of to...

The study of methods for obtaining base layers cadmium telluride the creation efficient solar cells on a flexible substrate, intended backup power supply security systems and facility control. Considering that polyamide film is stable up to temperature 450 °С, formation based substrates was carried out by method DC magnetron sputtering. Using chosen method, experimental samples micromodules sub...

Polymeric composites (PC) of tribological applications with a high level physical, mechanical and thermal properties based on aromatic polyamide silica gel have been developed. Regularities obtained that describe the effect filler content in PC friction coefficient, temperature surface intensity linear wear rate studied PC-steel pair. It was found optimal polymer matrix is 10 wt %. The morpholo...

The following investigation shows the experimental evaluation of a transient heat load centered on corrosion inhibitor coating employed in epoxy polyamide primary. temperature at which film initiated thermal deterioration increased with heating rates. This is Deft Inc.'s high- quality solid A single inch diameter lamp two types aluminum substrates was focused xenon flashlight: AA2024- T4 and AA...

Due to the poor compatibility caused by large difference in hydrophilicity and interface between polylactic acid (PLA) cellulose acetate (CA), blending of two materials is difficult application limited. To solve this problem, a type polyamide amine (PAMAM) dendrimer was introduced modify PLA/CA blends work. The results showed that PAMAM could improve blends, promote distribution CA crystallizat...

BACKGROUND Gene-specific targeting of any protein-DNA complex by small molecules is a challenging goal at the interface of chemistry and biology. Polyamides containing N-methylimidazole and N-methylpyrrole amino acids are synthetic ligands that have an affinity and specificity for DNA comparable to many naturally occurring DNA-binding proteins. It has been shown that an eight-ring hairpin polya...
