• New device can measure toxic lead within minutes
  

  Rutgers researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes - far faster than currently available laboratory-based tests, which take days. The affordable lab-on-a-chip device could also more

• Phenyl addition made a poison useful for a chemical reaction in catalysis
  

  Scientists from Tokyo University of Agriculture and Technology (TUAT), Japan, have discovered that a catalyst poison, which deactivates homogeneous catalysts, can be "reborn" as an efficient ligand by introduction of a substituent, in chemical reactions. This finding is of service to expand the liga more

• The cycling of poisonous chemicals from the past
  

  Persistent organic pollutants are toxic chemicals that cannot decompose in nature, or only do so very slowly, and are harmful to the environment. Through accumulation along food chains they also have significant negative effects on human health. Nowadays, many of them are banned. Traces of those com more

Microbots zoom around water, destroying bacteria

One day, the tiny robot you see here could help clean up contaminated water. In places where potable sources are scarce, they can destroy disease-causing bacteria in its path and unlike conventional disinfectants, the microbots can be removed easily with a magnet. more

• NASA Curiosity rover hits organic pay dirt on Mars

  Since NASA's Curiosity rover landed on Mars in 2012, it has sifted samples of soil and ground-up rock for signs of organic molecules—the complex carbon chains that on Earth form the building blocks of life. Past detections have been so faint that they could be just contamination. Now, samples taken more

• HPLC with non-specific detection in pharmaceutical quality control
  

  Impurity testing is an essential part of pharmaceutical quality control because toxicity and content of impurities contained in drug products can impair patient safety. This requires suitable, validated analytical methods. more
