Sorption in disordered porous media
The lattice-gas model of sorption in disordered porous media is studied for a variety of settings, using existing, updated and newly developed numerical techniques. Firstly, we construct an efficient algorithm to calculate the exact partition function for small lattice-gas systems. The exact …

Oil sorption behavior of fibrous substrates
… provides little information regarding the oil sorption behavior of raw cotton and its comparison with synthetic fibers. This study aims at investigating the oil sorption behavior of raw cotton. The effect of absorption time, cotton micronaire, and oil type on the oil sorption capacity has been …

Surface Sorption Properties of Halophilic Archaea
… complexation models (SCMs) for metal-Archaeal adsorption reactions were developed by combining sorption data with the results of acid-base titrations of the Archaeal surface. The resulting SCMs were robust and could be utilized to determine metal mass distribution in more complex multi-component …

Sorption of organic compounds on oil shale materials and sorption of selected chemicals on a Western soil
The sorption capacity of a raw shale (Anvil Points), three spent shales, (Antrim, Oxy 6, and Run 16), and a western soil for three organic compounds (2-Hydroxynaphthalene, 1,2,3,4-Tetrahydroquinoline, and 2,3,5-Trimethylphenol) was evaluated by batch and column sorption studies. In addition, the …

Measurements of fission product sorption on graphite
… (VHTRs) require data for fission product (FP) adsorption on graphite at high temperatures. The adsorption and vapor pressures of silver on nuclear moderator grade IG-110 graphite were measured in the range of 1000-1400K. Knudsen Effusion Mass Spectrometry (KEMS) was used for vapor pressure …

Structure and Sorption Behaviour of Liposomal Dispersions
Sommige surfactants vormen dubbellagen bij het dispergeren in water. Door mechanische agitatie sluiten deze dubbellagen zich vaak tot liposomen, ook wel vesikels genoemd. In de dubbellagen kunnen zowel amfifiele als hydrofobe stoffen sorberen terwijl hydrofiele stoffen kunnen ingesloten worden in …

Hydrogen sorption in palladium doped microporous materials
… room temperatures. XRD, Temperature Programmed Desorption and hydrogen sorption measurements were used to characterise the as-received and palladium doped porous materials. The hydrogen uptakes of as-received Maxsorb (activated carbon), Black Pearls (carbon furnace black) and MOF-5 (metal organic …

Characterization of Aluminum Surfaces: Sorption and Etching
While aggressive anions such as chloride are usually studied to elucidate corrosion processes to work ultimately toward inhibition, its corrosive properties can be successfully utilized in the drive for higher energy and smaller-scale storage devices. Fundamental information gained regarding anion …

Sorption and desorption of selenium in cement formulations
… water/solids ratios tend to maximize selenium sorption while adding silica fume or 5% clay appears to decrease sorption. A sorption/desorption study was conducted on cementitious formulations containing three levels of w/s ratios (45%, 50%, 55%) and three weight percentages of clay (0%, 3%, 5%) …
