In this study, the influence of dyeing on the antibacterial efficiency of polyamide and polyester fabrics loaded with colloidal Ag nanoparticles and the influence of the presence of Ag nanoparticles on the color change of dyed fabrics were investigated. Dyes C.I. acid green 25 and C.I. disperse blue 3 were used for dyeing of polyamide fabrics, while dye C.I. disperse violet 8 was used for dyein...

The extraction and quantitative analysis of low molar mass compounds in polymers is an analytical challenge. It is also important from a practical point of view because the low molar mass compounds in time will migrate from the polymers into the surrounding environment. It is especially important to gain knowledge about the migrating compounds in applications such as medical implants, packaging...

The process of obtaining aerated (filled with air bubbles) polymer coatings has been developed and investigated by the method flame spraying an assessment their ability to damp vibrations. A technology for controlled formation while using capabilities ОИМ (OIM) 050 thermal atomizer design which consists in providing a concurrent flow between torch jet powder material. experiments have carried o...

The impact of whitefly-transmitted begomoviruses (Geminiviridae) on tomato yields depends on plant age at time of infection, and is greatest during the first 5 weeks after germination (critical period). A preventative strategy designed to minimize contact between the vector and the tomato plant by masking the crop with living ground covers during the critical period was promoted among small-sca...

ABSTRACT This study aimed to evaluate the productive performance, dry matter intake, apparent digestibility and ingestive behavior of feedlot calves fed corn silage from feed out face trench silos with different types sealing. The animals were divided into three treatments four repetitions: Conventional seal - double-sided polyethylene 110µm thickness; Double-sided 200µm Double composed double ...

Forward Osmosis (FO) polyamide thin-film composite membranes have been prepared by interfacial polymerization using commercial UF polyethersulfoneas membrane support. Different interfacial polymerization times (10s, 30s and 60s) in the organic solution containing trimesoyl chloride (TMC) at constant mphenylenediamine (MPD) concentration (2% w/v) were studied. The synthesized polyamide membranes...

We have developed methods for the synthesis of peptide-oligodeoxyribonucleotide conjugate molecules in particular, and polyamide-oligonucleotide conjugates in general. Synthesis is carried out by a solid-phase procedure and involves the assembly of a polyamide on the solid support, conversion of the terminal amino group to a protected primary aliphatic hydroxy group by reaction with alpha, omeg...

Plastics are essential materials, but their extensive production poses a threat to the environment. Biobased plastics provide an alternative, that reduce, in many cases, perdurability. The degradation of conventional (polyethylene (PE)/polyethylene terephthalate (PET) and polyamide (PA)/polypropylene (PP)- ethylene vinyl alcohol (EVOH)-PP) polylactic acid (PLA)-based materials was evaluated thr...

A series of hairpin pyrrole-imidazole polyamide-fluorescein conjugates were synthesized and assayed for cellular localization. Thirteen cell lines, representing 11 human cancers, one human transformed kidney cell line, and one murine leukemia cell line, were treated with 5 microM polyamide-fluorescein conjugates for 10-14 h, then imaged by confocal laser scanning microscopy. A conjugate contain...
