Understanding the intricacies of how nanoparticles undergo chemical transformations could lead to better ways to tailor their composition, which can lead to advanced material properties.



A new study by Baylor University environmental health researchers found that zebra fish exposed to several different technical mixtures of polybrominated diphenyl ethers (PBDEs) – a common fire retardant – during early development can cause developmental malformations, changes in behavior and death.



A novel way to immobilise radioactive forms of iodine using a microwave, has been discovered by an expert at the University of Sheffield.



(PhysOrg.com) -- Stinging from humiliating defeat in World War I, Germany’s Nazi regime seized on technology developed by chemists Franz Fischer and Hans Tropsch that enabled the coal‐rich, petroleum‐poor country to produce synthetic fuels for its military machine. Research in Fischer‐Tropsch or “FT” synthesis waned in the latter half of the 20th century but, like “a bubblin’ crude,” has resurfaced in recent years with growing interest in alternative fuels.
