It may be exothermic or endothermic processes ranging from very small to very large energy magnitudes. The elementary step in chemisorption often involves large activation energy (activated adsorption). This means that the true equilibrium may be achieved slowly. In addition, high www.intechopen.com ...
The biological reac- tions responsible for cellular functions occur either exothermically or endothermically at particular locations within a cell, such as organelles. Hence, temperature distributions inside a living cell reflect the thermodynamics and functions of organelles6. Recently, the quantification ...

A CSTR with two irreversible consecutive reactions -the first exothermic, the second endothermic -shows under numerical simulation a sequence of period- doubling bifurcations of a limit cycle: an ordinary limit cycle gives way to one of ... C Kahlert,OE Rössler,A Varma - Springer Berlin Heid...
a sealed space for effecting indirect heat exchange between the two compartments; a reactive material capable of sustaining an endothermic or an exothermic reaction when mixed with an activating agent is held in one of such compartments. ... A. Louis Jagoe III 被引量: 6发表: 1985年 ...
For SAT-5 film, endothermic and exothermic peaks corresponding to the α–β phase transition of Ag2Te were detected at 419 and 409 K during both heating and cooling processes, respectively [24,25]. This suggests that the small particles around large grains on free side were α-Ag2Te ...
A reactor for carrying out endothermic or weakly exothermic reactions, in particular for the treatment of contaminated liquefied, liquefiable and/or solid hydrocarbons and hydrocarbon compounds with hydrogen, has at least one feedline for substrate (5) to be treated, hydrogen-containing reagent (7) ...
