• Sensitive to Oxygen: Phosphorescent iridium(III) porphyrin complexes, new tunable oxygen indicators

  Monitoring the amount of oxygen in living tissues accurately is a valuable tool in biomedical science, because it enables the elucidation of the course of metabolic processes or the detection of diseases or anomalies. Metal complexes that absorb and emit light are useful as sens more

• Researchers use improved nanogenerators to power sensors based on zinc oxide nanowires
  

  By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy. The new devices can measure the pH of li more

• Superatoms mimic elements: Research gives new perspective on periodic table
  

  Transforming lead into gold is an impossible feat, but a similar type of "alchemy" is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. Acc more

• Particle Analysis: Quality Control of Catalysts with Digital Image Processing
  

  Catalysts are widely used as an important auxiliary material in the chemical and petrochemical industry. They are able to accelerate chemical reactions by lowering the activation energy, i.e. they change reaction kinetics. Thus, using catalysts in industrial processes has the advantage of higher productivity combined with less energy consumption. more
