Polymer adsorption on rough surfaces
10.1016/j.coche.2018.03.001 2018-04-07 The adsorption of polymers on smooth or atomistically flat substrates has been a topic of study for decades, and such systems are well-characterized. However, there is little knowledge of the complex interfaces created by adsorption on heterogeneous surfaces:... |

Flexibility of metal-organic frameworks for separations: utilization, suppression and regulation
10.1016/j.coche.2018.03.008 2018-04-05 Framework flexibility and dynamic behavior are unique characteristics of metal-organic frameworks (MOFs). Gate-opening, as one of flexibility modes of MOFs, is mainly triggered by guest adsorption. The gate-opening feature of MOFs is influenced by the types o... |

Facts and alternative facts in chemical kinetics: remarks about the kinetic use of activities, termolecular processes, and linearization techniques
10.1016/j.coche.2018.03.007 2018-03-31 This contribution examines three different controversial questions that arise in the everyday practice of chemical kinetics. First, it is argued that concentrations should be used as independent variables in rate equations rather than activities. The occasion... |
