Thermodynamical Studies of Irreversible Sorption of CO2 by Wyodak Coal

Differential scanning calorimetry (DSC), temperature programmed desorption mass spectrometry (TPD-MS) and small angle neutron scattering (SANS) were used to investigate CO2 uptake by the Wyodak coal. Adsorption of carbon dioxide on Wyodak coal was studied by DSC. The exotherms evident at low temperatures are associated with the uptake of CO2 suggesting that carbon diox...

Studies on Indium Sorption from Iodide Medium by Polyurethane Foam

A sorção de iodeto de índio em espuma de poliuretano do tipo poliéter (EPU) foi investigada. O sistema apresentou rápida cinética e máxima sorção numa faixa significativa de meio ácido ou básico e razões de distribuição acima de 10 L kg ([KI] 0.6 mol kg). A análise do equilíbrio de sorção indicou o tetraiodo-indato (MInI 4 )como a principal espécie sorvida na matriz da espuma. A isoterma de Lan...

Studies in Bacterial Metabolism. Vii. by Arthur

A most fundamental principle of bacterial metabolism may be expressed concisely by stating that “Fermentation takes precedence over putrefaction;“’ that is to say, bacteria in general which can utilize both carbohydrate and protein, act upon the former in preference to the latter when bot,h are present in the same medium. In view of the confusion attending the use of the terms putrefaction and ...

Biological Activity and Bio-Sorption Properties of the Ti2C Studied by Means of Zeta Potential and SEM

The expanded Ti2C MXene phase was synthesized from the commercial Ti2AlC MAX phase using classical acidic aluminium extraction method. The individual expanded Ti2C sheets were characterized by the diameters of between 26 and 61 nm and formed the specific network of slit-shaped pores in the size range of 3–5 nm. The BET specific surface area of expanded Ti2C was ca. 42% higher in comparison with...
