• Keeping beverages cool in summer

  In spring a person's thoughts turn to important matters, like how best to keep your drink cold on a hot day. Though this quest is probably as old as civilization, University of Washington climate scientists have provided new insight. It turns out that in sultry weather condensation on the outside of more

• Jet fuels from biomass waste

  A four-step process to produce alkanes in the range of jet and diesel fuel from the biomass of wood processing and pulp mills has been reported in Green Chemistry. In the search for alkanes more suited for transport fuels, previous researchers in this area carried out tests using model biomass comp more

• The Amazon rainforest -- a cloud factory
  

  The forest in the Amazon Basin produces its own rain. During the wet season, aerosol particles, which serve to condensate clouds and precipitation here, mainly consist of organic material. These aerosols are released by the rainforest itself. This has been demonstrated by scientists from the Max Pla more

• Innovative Vacuum Regulation for Rotary Evaporators
  

  Different methods of vacuum regulation in rotary evaporators are compared according to their benefit for the user. Essential criteria of such analyses are process time, rate of solvent recovery, ease of handling, and flexibility. Speed controlled diaphragm pumps with automatic regulation feature obvious advantages and an extremely long performance life of wear parts more

• "Green Chemstry" in the Laboratory
  

  The term "green chemistry" is commonly used to describe chemical procedures which meet specific requirements with regards to the conservation of resources and protection of the environment. The objective is to avoid undesired by-products by selecting adequate reaction procedures and media. A typical example is the production of bio fuel which has become an ecologically friendly alternative for many drivers. more

• Benzo‐Annulated Steroids: Synthesis of Octahydro‐indeno‐phenanthrenes by Formal [3+3] Cyclocondensation Reaction with 1,3‐Bis[(trimethylsilyl)oxy]buta‐1,3‐dienes

  Abstract Octahydro‐indeno‐phenanthrenes, benzo‐annulated steroids, were prepared by formal [3+3] cyclocondensation reaction of 1,3‐bis[(trimethylsilyl)oxy]buta‐1,3‐dienes with the silyl enol ether of 16‐formylestrone methyl ether. more

• Tandem Synthesis of Pyrroloacridones via [3 + 2] Alkyne Annulation/Ring-Opening with Concomitant Intramolecular Aldol Condensation

  An efficient cascade strategy for the direct synthesis of pyrrolo[3,2,1-de]acridones 4a–v, 5a–h from iodo-pyranoquinolines 2a–i by the palladium-catalyzed regioselective [3 + 2] alkyne annulation/ring-opening followed by intramolecular aldol condensation under microwave irradiation is described. The more

• Synthesis, Structure, and Properties of Alternating and Random Poly(styrene-b-butadiene) Multiblock Copolymers

  We report a synthetic method for the preparation of well-defined poly(styrene-b-butadiene) (PS-PB)n multiblock copolymers using a combination of living anionic polymerization and urethane based polycondensation along with an assessment of the associated microphase morphology and thermal and mechanic more
