New C72 Series Injectors Many of the latest analytical techniques require systems capable of pressures up to 15,000 or 20,000 psi. The new C72 series injectors from Cheminert feature a proprietary stator coating that permits these pressures. The injectors use the same mounting system as the widely used Cheminert C2 series HPLC injectors. Learn more>>>

Laboratory Hybrid Distillation Systems For Heat-Sensitive Materials These systems combine the gentle short residence time evaporating principle of of gentle, short residence time of dynamically transported wiped thin films with the highly efficient separation capability of fractional distillation columns. The technique of choice where the single theoretical plate of an evaporator alone does not provide required product purity, and where a conventional multiple theoretical plate distillation system alone causes thermal degradation. Versatile design allows configuration for Molecular (short-path) Distillation, Evaporation, or Fractionation, plus choice of glass, 316L SS, Hastelloy, other materials. Applications assistance, feasibility testing and custom toll processing support is available.

Atomic-Resolution Structure of a Ribozyme Yields Insights Into RNA Catalysis
Which came first, nucleic acids or proteins? This question is molecular biology's version of the "chicken-or-the-egg" riddle. Genes made of nucleic acids (DNA or RNA) contain the instructions for making proteins, but enzymes made of proteins are needed to replicate genes. For those who try to understand how life originated, this once seemed an intractable paradox.

The solution came with the discovery 20 years ago that certain types of RNA can act as enzymes, catalyzing reactions just as enzymes made of protein do. This means, in principle, that a single type of molecule, RNA, might be able to both encode information and replicate it. The idea that the first self-replicating molecules in a pre-biotic primordial soup were composed of RNA, known as the "RNA World" hypothesis, is one of the central tenets upon which many theories of the origin of life are now based.....more>>>



‘Micro-boxes’ of Water Used to Study Single Molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule “boxes” for small numbers of biomolecules. The unusually simple containment method may enable easier experiments on single molecule dynamics and perhaps lead to the development of molecule-sorting devices that might be used for medical screening or biotechnology research. The work was reported in the July 3 issue of Applied Physics Letters....more>>>

Rice Scientists Unveil 'Nanoegg'
Researchers at Rice University's Laboratory for Nanophotonics (LANP) have unveiled the "nanoegg," the latest addition to their family ultrasmall, light-focusing particles. A cousin of the versatile nanoshell, nanoeggs are asymmetric specks of matter whose striking optical properties can be harnessed for molecular imaging, medical diagnostics, chemical sensing and more....more>>>
