Facile Synthesis of a Magnetic Glucose-Based Hyper-Cross-Linked Polymer by Dual-Role Ferric Chloride for Nitrophenol Removal from Sewage

“…4−6 A series of related researches have determined that the most effective strategy for treating nitrophenols is adsorption using porous materials, which does not produce any additional toxic metabolites. To date, many fascinating materials have been utilized for nitrophenol removal, such as activated carbons, 7,8 zeolites, 9,10 graphene oxides, 11,12 ionic liquids, 13,14 metal−organic frameworks, 15,16 and covalent organic frameworks. 17,18 However, carbon-based materials rely on a single interaction force and have poor structural regulation.…”

Embedding Mixed Sorbents in Binder: Solid-Phase Microextraction Coating with Wide Extraction Coverage and Its Application in Environmental Water Analysis

“…14 The extraction coverage of a certain SPME device is a major concern when extracting multiclass contaminants in environmental water samples, as the extraction selectivity is restricted by the selected coating material. In response, researchers have attempted to improve performance by developing novel SPME coatings based on metal−organic frameworks, 15,16 covalent organic frameworks, 17,18 graphene, 19,20 MXenes, 21 layered double hydroxides, and carbon-based nanocomposites. 22−24 However, in most applications, only one type of SPME coating can be used, which restricts the analysis to certain classes of target compounds with similar physicochemical properties.…”

For example, while C18/PDMS coatings provide good extraction performance for nonpolar analytes (e.g., polyaromatic hydrocarbons), they are unable to extract polar analytes (e.g., artificial sweeteners). , Similarly, SPME devices with anionic exchange coatings provide good extraction performance for anionic compounds (e.g., polyfluorosulfonic acid), but relatively poor performance for most drugs of abuse, which tend to be positively charged in environmental water samples. , This issue restricts the use of SPME techniques for regular water monitoring.…”

Review and perspective on polyhedron model for estimating thermodynamic properties of oxides

“…Thermodynamic modeling of phase equilibria and chemical reactions in multicomponent systems is an indispensable part of the development of advanced materials and processes. Oxide-based materials have many applications, such as glass, 1 ceramics, 2,3 reinforcements in metallic matrix composites, 4 thin films and coatings, 5,6 materials for magnetic recording, 7 fuel cells, 8,9 hightemperature superconductors, 10,11 health, 12,13 cement, 14,15 energy storage, 16,17 water decontamination, 18,19 and process metallurgy. 20,21 Despite the large volume of data available, there are numerous important oxide compounds with unknown thermodynamic properties.…”
