• Understanding properties of nanoparticles and quantum dots using Hansen Solubility Parameters

  Devices based on quantum dots and smart nanoparticles are currently getting a lot of attention. For instance, the colours, contrast and brightness of displays based on quantum dots provide benefits for users of TVs and phones. In addition, such particles can create value when incorporated into novel more

• Asphaltene analysis takes a giant step
  

  Rice University researchers have developed an easy and accurate technique to detect and quantify the amount of asphaltene precipitated from crude oils, which bedevils the oil industry by clogging wells and flow lines.Asphaltene is a complex of hydrocarbon molecules found in crude. As the name sugges more

• Laying down a discerning membrane

  One of the thinnest membranes ever made is also highly discriminating when it comes to the molecules going through it. Engineers at the University of South Carolina have constructed a graphene oxide membrane less than 2 nanometers thick with high permeation selectivity between hydrogen and carbon di more

• Design Concepts in Absorbance Optical Systems for Analytical Ultracentrifugation

  Analytical ultracentrifugation is a powerful technique for analyzing particles in solution, and has proved valuable for a wide range of applications in chemistry, biochemistry and material sciences for many years. The field is presently seeing a resurgence of instrument development from commercial a more

• Improved MOF nanoparticle recovery and purification using crosslinked PVDF membranes

  Crosslinked PVDF-membranes are demonstrated to offer a viable alternative for centrifugation in the preparation of MOF-particles, thus realising new opportunities at lab-scale and continuous production at large-scale. The membranes combine extreme-pH with solvent stability, thus enabling application more

• Eco-friendly environmental trace analysis of thorium using a new supramolecular solvent-based liquid-liquid microextraction combined with spectrophotometry
