• Researchers image atomic structural changes that control properties of sapphires

  Materials scientists from Case Western Reserve University and the Institute of Solid State Research in Jülich, Germany have produced particularly clear changes in the atomic structure of sapphire following deformation at high temperatures. Peering through an electron microscope down to a level wher 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

• Label-free single-molecule DNA sequencing

  Microfluidics can be used to trap a single DNA–enzyme complex in its native state, without immobilisation. These studies have usually been performed by immobilising either the enzyme or the DNA on a glass slide, but this may modify their properties, and make it difficult to analyse the products. Th more

• Fugene® HD Transfection Reagent: Superior Performance for Challenging Expression Studies
  

  The ability to efficiently introduce foreign molecules into cells constitutes an important tool in any laboratory and facilitates studies of gene regulation and protein function. A plethora of transfection methods have been developed for transfer of DNA into mammalian and animal cells. Those methods either utilize the physicochemical properties of the vector-carrier of the DNA or use mammalian viruses. In the first group of methods, some classic techniques are well-known, such as: calcium phosphate, DEAE-dextran, electroporation liposome-mediated delivery, direct microinjection/biolistic particle delivery, and non-liposomal multi-component reagents. Viral vector systems use both DNA (Adeno-) and RNA (Retro-, Lenti-) viruses. 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

• Reaching the Next Level of Microwave-assisted Organic Synthesis

  Microwave-assisted organic synthesis (MAOS) has become an increasingly popular discipline in modern chemical method development. At first, reaction optimization and method development on a small scale were the main areas of interest in MAOS. However, the growing acceptance and success of this innovative microwave technology revealed the necessity for large-scale synthesis of valuable compounds using microwave heating, especially in industrial laboratories more
