Exempel på hur man kan använda ISOTHERMS i en mening

• Herlofson proposed a modification to the emagram that allows straight, horizontal isobars and provides for a large angle between isotherms and dry adiabats, similar to that in the tephigram.
• In subsequent studies using the BET interpretation of nitrogen and water vapor adsorption isotherms, the reported area occupied by an adsorbed water molecule on fully hydroxylated silica ranged from 0.
• However, when the compressibility factors of various single-component gases are graphed versus pressure along with temperature isotherms many of the graphs exhibit similar isotherm shapes.
• In the tephigram, isotherms are straight and have a 45 degree inclination to the right while isobars are horizontal and have a slight curve.
• Heat flows into the loop through the top isotherm and the left isochore, and some of this heat flows back out through the bottom isotherm and the right isochore, but most of the heat flow is through the pair of isotherms.
• In the emagram, the dry adiabats make an angle of about 45 degrees with the isobars, isotherms are vertical and isopleths of saturation mixing ratio are almost straight and vertical.
• thumb He found that Type II and Type III isotherms require highly porous materials or desiccants, with first monolayer adsorption, followed by multilayer adsorption and finally leading to capillary condensation, explaining these materials high moisture capacity at high relative humidity.
• Yaghi made three breakthroughs that transformed the traditional coordination polymers into architecturally robust and permanently porous MOFs which are being widely used today: (1) crystallization of metal-organic structures where metal ions are joined by charged organic linkers as exemplified by carboxylates to form strong bonds (Published in 1995); (2) introduction of metal-carboxylate clusters as secondary building units (SBUs), which was the key to building architecturally robust frameworks exhibiting permanent porosity as he proved by measuring for the first time their gas adsorption isotherms (Published in 1998); (3) realization of ultra-high porosity with MOF-5 (Published in 1999).
• DVS was originally developed to replace the time and labor-intensive desiccators and saturated salt solutions used to measure water vapor sorption isotherms.
• Such a pattern packs isotherms and moisture so that, at the point called Z, warm air is advected from the South (TI) while cold air comes from the North (PI); then the flow spreads the airmass from one to the other, forming a stationary front.
• Since separation processes run with mixtures of different components, measuring several breakthrough curves results in thermodynamic mixture equilibria - mixture sorption isotherms, that are hardly accessible with static manometric sorption characterization.
• The sorption isotherms of these materials, demonstrate typical hysteric behavior, which is still under discussion for its causes.
