Cell wetting and dewetting in soft substrates present a collection of non-cohesive cohesive patterns. Prediction this wide diversity is critical importance order to design experiments with polar active matter under confinement. Although vivo, cells the extracellular matrix (ECM) are enfolded by flexible substrates, at experimental realizations, hard boundaries frequently employed. Here, elastic...

the aim of this study was to investigate the removal of toluene from air through nano-graphene modified by ionic liquid (ng-il). the batch adsorption experiments in glass bottle of gas chromatography equipped with flame ionization detector (gc-fid) were used. graphene ultrahigh-quality synthesized by substrate-free gas-phase method in a single step and graphene sheets were deposited with ionic-...

This paper reports on the preparation and characterization of thin films of silicon nitride deposited on heated silicon substrates from Si(CH, ),-NHS-H, mixtures activated at room temperature by an a-c. discharge at low frequency. The films were deposited at 800°C. Deposition rate as well as refractive index were measured and several parameters were systematically varied , including deposition ...

gases such as no and co play important roles both in normal physiology and in disease. in recent years, interest has been directed towards other naturally occurring gases, notably h 2 s, which is produced in body by three enzymes namely cbs (cystathionine beta synthase), cse (cystathionine gamma lyase) and mst (3-mercaptopyruvate sulfurtransferase), present in mitochondria and/or cytosols where...

abstract: background: release of volatile organic compounds (vocs) in industrial and urban area have adverse effects on human health and  environment. the aim of this study was removal of gaseous toluene, as the most of pollutants among vocs, by using of tio 2 nanoparticles coated on nickel foam substrate. methods: tio 2 nanoparticles prepared by sol gel method and coated on nickel foam. morpho...

this paper discusses different important gas permeation models such as “maxwell”, “bruggeman”, “lewis-neilson”, and “pal” models to predict “mixed matrix membranes” (mmms) performance. the main parameter considered and discussed is the permeability of hydrogen on carbon nanotubes (cnts)-mmm. for evaluation of the theoretical models, experimental data of permeability for h2 were compared to the ...

the state of works of art exhibited inside museums can be strongly influenced by indoor air quality, due to chemical activity of gaseous pollutants and particulate matter. for that reason it is important to carry out periodic air quality controls to check if the concentration levels of air pollutants comply with the limits specified by the national laws. in this work we show results obtained in...

A series of TiAlON coatings were synthesized in a gaseous mixture of argon, nitrogen and oxygen by cathodic arc evaporation method using a Ti–Al mosaic target. Oxidation of coatings was carried out by heating the coated samples at the temperatures of 500, 600, 700, and 800°C for 1 h in air atmosphere. It was found that heat treatment changed the microstructure and composition of the coating. Th...

We report a case of male corpse colonization found inside residence in the municipality Areia, Paraíba, Brazil. The body was gaseous stage decomposition and colonized by fly larvae. reared larvae collected at crime scene on temperature-controlled. supplied beef as feeding substrate for until adult emergence to allow taxonomic identification. Three specimens Peckia (Squamatodes) ingens emerged l...

The removal of copper dissolved in liquid stags by pyrometalIurgical means such as gaseous reduction and sulfidization is thermodynamically investigated. The lowest level possible for copper content is theoretically determined and compared. The results show that gaseous reduction is not as effective as sulfidization. Slags with very low levels of dissolved copper can be obtained with sulfide tr...
