• Researchers pinpoint how trees play role in smog production

  After years of scientific uncertainty and speculation, researchers at the University of North Carolina at Chapel Hill show exactly how trees help create one of society's predominant environmental and health concerns: air pollution. It has long been known that trees produce and emit isoprene, an abun more

• X-ray analysis could boost legumes, thus reducing fertilizer pollution
  

  The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor more

• When boron butts in

  For Nature and chemists alike, making atmospheric nitrogen available for the formation of more complex nitrogen compounds is both essential and difficult. Paul Chirik and Scott Semproni at Princeton University, USA, report the first examples of the use of group 4 metallocene complexes for boron–nitr more

• Burn injuries under freezing (labor protection) conditions?
  

  "A little splash of liquid nitrogen hasn't hurt anybody" - this happens to be a widespread opinion in many laboratories. The real dangers connected to cryogenic gases many people had to learn firsthand, unexpected and painful. Skin irritation, cell and tissue damage or severe burn injuries may occur, depending on the type of contact and exposure time. There are less possibilities of medical treatment than for injuries caused by influence of heat 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

• Accurate Mass and TIPTM: Two Dimensions for Elemental Composition Determination: microTOFTM Featuring Unique TIPTM
  

  The ESI-TOF mass spectrometers micrOTOF and micrOTOF focus do not only provide accurate mass measurements but additionally describe the True Isotopic Pattern TIPTM. For molecular formula generation this unique combination significantly reduces the number of possible formula candidates and the elemental composition of compounds with molecular weights far higher than 500 Da can unequivocally be determined more

• Luminescence thermochromism of two entangled copper-iodide networks with large temperature-respondent emission shift

  The luminescence thermochromism properties of two entangled copper(I)-iodide coordination polymers formulated [Cu4I4(dmimpr)2]n (1) and [Cu6I6(dimb)3]n (2) (dmimpr = 1,3-di(2-methyl-imidazol-1-yl)propane, dimb = 1,4-di(imidazol-1-yl)butane) are reported. Upon cooling by liquid nitrogen, their solid- more

• Aerobic C-H Amination of Tetrahydrocarbazole Derivatives via Photochemically Generated Hydroperoxides

  A Brønsted acid catalyzed C-H functionalization via Intermediate PeroxideS (CHIPS), generated photochemically, allows the oxidative coupling of indole derivatives with a variety of nitrogen nucleophiles. The reaction can be performed one-pot and requires only visible light, elemental oxygen, a Brøns more
