  • Spatial conformation of condensed state graphene is fundamentally important for its material properties
  • while its rational design or control is of great challenge. Herein
  • reduced graphene oxides with diverse crumple conformations are synthesized facilely and effectively by using electrostatic force from cation-oxidized functional group and cation-π interactions through NaCl/MgCl2/AlCl3 assisted hydrothermal reduction. A phase map for crumple conformation and gel configuration transitions of the reduced graphene oxides is established
  • where intramolecular effect of mono-valent cation and intermolecular effect of di-/tri-valent cations are captured and utilized to tune the crumple degree or gelation process.

  • methods of optimizing the coagulant dosage in wastewater treatment processes typically rely on the use of labor- and material-intensive jar testers
  • which are inadequate when coagulation processes require frequent adjustments due to variations in properties of the incoming feed. Analytical centrifuges (ACs) employ an integrated optics system that simultaneously monitors the position of the boundary between two separating phases in multiple samples of fairly low volumes (∼2 mL) – thus it was expected that ACs would be ideally suited to study the stability and settling kinetics of coagulation treatment processes

  • stability of water-based pigment dispersions is a key factor in determining their utility in ink-jet applications
  • and the appropriate choice of dispersant plays a special role. Among the pigment formulations tested to date
  • literature data on magenta pigments are very limited. Thus
  • the goal of this work was to study the influence of the type and loading of dispersants on the quality and stability of quinacridone magenta pigment dispersions. Three different commercially available dispersants were tested: (1) a cationic styrene-maleic anhydride copolymer
  • (2) an anionic polyacrylate
  • and (3) a nonionic alkyl ethoxylate. Pigment and dispersing agents were analysed using the Fourier Transform–infrared method. The stability of pigment dispersions was determined by comparative studies of changes in the pigment particle size
  • viscosity
  • pH
  • filtration time
  • optical density and gloss during the accelerated ageing test. LUMiFuge analysers used for evaluations of the instability of the dispersions.
