Exempel på hur man kan använda ADSORB i en mening

• Pressure swing adsorption (PSA) oxygen concentrators use a molecular sieve to adsorb gases and operate on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals at high pressure.
• Adsorbate molecules adsorb readily because they lower the surface free-energy of the substrate The monolayer packs tightly due to van der Waals interactions, thereby reducing its own free energy.
• One is the change of the surface structure to a metastable structure, and another is cleaning the surface by the photodecomposition of dirt such as organic compounds adsorbed on the surface, after either of which water molecules can adsorb to the surface.
• The difference is that in adsorption refrigeration, the refrigerant or adsorbate vapour molecules adsorb onto the surface of a solid instead of dissolving into a liquid.
• According to TSK model, surface atoms in nanocrystals can occupy terrace, step or kink positions: each site has a different tendency to adsorb reactants and to let them move along the surface.
• In this mechanism, suggested by Irving Langmuir in 1921 and further developed by Cyril Hinshelwood in 1926, two molecules adsorb on neighboring sites and the adsorbed molecules undergo a bimolecular reaction:.
• Suspended-growth systems include activated sludge, which is an aerobic treatment system, based on the maintenance and recirculation of a complex biomass composed of micro-organisms (bacteria and protozoa) able to absorb and adsorb the organic matter carried in the wastewater.
• In panchromatic emulsions, the sensitivity of the silver halide crystal is enhanced by sensitizing dyes that adsorb on the crystal surface.
• Since the stationary phase is hydrophilic in this technique, and the mobile phase is non-polar (consisting of organic solvents such as hexane and heptane), biomolecules with hydrophilic properties in the sample adsorb to the stationary phase strongly.
• They adsorb on metal surfaces and self-assemble to form incompressible monolayers which prevent asperity contact and reduce friction and wear.
• Some fly ashes, typically those with high unburned carbon contents, tend to adsorb high amounts of AEA, i.
• Sticking coefficient is the term used in surface physics to describe the ratio of the number of adsorbate atoms (or molecules) that adsorb, or "stick", to a surface to the total number of atoms that impinge upon that surface during the same period of time.
• The VLS mechanism circumvents this by introducing a catalytic liquid alloy phase which can rapidly adsorb a vapor to supersaturation levels, and from which crystal growth can subsequently occur from nucleated seeds at the liquid–solid interface.
• Later work by Hardy and Doubleday showed that this property was related to the ability of polar lubricants to adsorb and form close-packed monolayers on the sliding surfaces.
• The surfactant molecules adsorb on the surface of emulsion by creating a dispersion of droplets, which reduces interfacial tension and retards particle flocculation during mixing.
• In principle, atoms with lower coordination number (kinks and defects) tend to be more reactive and therefore adsorb the reactants more easily: this may promote kinetics but could also depress it if the adsorbing species isn't the reactant, thus inactivating the catalyst.
• Microplastics are concern because they have a tendency to adsorb pollutants on their surface, as well as an ability to bioaccumulate.
• Diffusive (or passive) sampling – A tube is packed with a single sorbent bed and allowed to adsorb analytes from the air diffusively.
• As MMCs are found to adsorb more water at low relative humidities compared to the best materials previously available, the hygroscopic zeolites, and MMCs can be used to keep humidity at extremely low levels where needed.
• Pressure swing adsorption (PSA) pressurizes and depressurizes a multicomponent gas around an adsorbent medium to selectively adsorb some components of a gas while leaving other components free-flowing.
