No risk of explosion when using hydrogen as GC carrier gas

Hydrogen as GC carrier gas provides good efficiency as well as faster separations than with helium or nitrogen. The safety risk of explosion can be eliminated more

• CCNY chemists design molecule that responds to stimuli

  The venus flytrap plant captures its prey when it senses the presence of an insect on the tips of its leaves. An amphiphilic molecule designed by chemists at The City College of New York acts in a similar manner by changing its structure when heated slightly and, then, reverting to its original form more

• Graphene: Singles and the few

  A timely review analyzing the correlation of synthesis methods and physical properties of single-layer and few-layered graphene flakes. A review of methods used for synthesizing both single and few-layer graphene and the resulting properties is presented by C.N.R. Rao and colleagues at the Jawaharla more

• Pivoting hooks of graphene's chemical cousin could revolutionize work of electron microscopes

  The single layer material Graphene was the subject of a Nobel prize this year but research led by a team of researchers at the University of Warwick has found molecular hooks on the surface of its close chemical cousin, Graphene Oxide, that will potentially provide massive benefits to researchers us 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

• Sum parameters "on trail"
  

  Identification of organic pollutants in wastewater is essential for performance evaluation, construction and operation of a wastewater treatment plant. Several parameters are currently used in wastewater analysis applications. The advantages of TOC analyses are apparent especially during continuous monitoring more
