• Ceresana Market Analysis: Expandable Polystyrene

  Global demand for expandable polystyrene (EPS) in the construction and packaging industries will slow down, but continues to increase. Important factors are the recovery of the construction sector after the financial and economic crisis in 2008/09, state-funded programs to improve energy efficiency, more

• Electrospun polymer fibres better than non-woven polymer fibres at mopping up oil from oil spills

  Electrospun polystyrene shell/polyurethane core fibres made by scientists in China have absorption capacities 2-3 times higher than reported for non-woven polypropylene fibres (widely used to clean up oil spills). Electrospun fibres are an ideal candidate for soaking up oil, as their structure means more

• Laser light guides micro-particles to their target

  US and German scientists have used laser light to guide micro-particles through a solution towards a target. The technique could be applied to transport the particles to specific locations inside living cells, they say. These so-called ‘micro-swimmers’ consist of a polystyrene sphere with one hemisp more

• Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization
  

  High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more

• Do you see the complete picture?
  

  Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more

• Good Reasons to Use ATR Libraries
  

  Transmission spectroscopy was the only method in general use until the early 1960s. The first applications of attenuated total reflection (ATR) or internal reflection spectroscopy were reported independently by Fahrenfort and Harrick. Especially macromolecular materials (rubbers, fibers, fabrics, coatings, laminates etc), which often failed to yield useful transmittance spectra, became accessible for infrared spectroscopic investigations by the ATR technique. Meanwhile, the ATR technique has been proven to be an extremely useful technique for material analysis and has become more widely used for all but gaseous samples. more

• High aspect ratio cylindrical microdomains oriented vertically on the substrate using block copolymer micelles and temperature-programmed solvent vapor annealing

  We report a novel, yet simple, method for the preparation of high aspect ratio cylindrical microdomains oriented vertically on a substrate by using block copolymer micelles and temperature-programmed solvent vapor annealing. Multilayered spherical micelles were first prepared by spin-coating of poly more

• d-Glucose Hydrogenation over Ru Nanoparticles Embedded in Mesoporous Hypercrosslinked Polystyrene

  The kinetics of d-glucose hydrogenation on the catalyst containing Ru nanoparticles in the matrix of hypercrosslinked polystyrene was studied. Two routes of the hydrogenation reaction were revealed; their rates differ by several digits. The first route includes the interaction of d-glucose with the more

• In situ thermal reduction of graphene oxide in a styrene–ethylene/butylene–styrene triblock copolymer via melt blending

  Abstract We report an in situ thermal reduction of graphene oxide (GO) in a styrene–ethylene/butylene–styrene (SEBS) triblock copolymer matrix during a melt‐blending process. A relatively high degree of reduction was achieved by melt‐blending premixed GO/SEBS nanocomposites in a Haake mixer for more
