• Detecting material defects in ship propellers

  They can weigh up to 150 tons, and it's not uncommon for them to measure nine meters or more in diameter: the ship propellers on huge tankers, container ships and cruise liners are invisible giants. Damage to these massive propellers could render a ship unmaneuverable – with unpredictable consequenc more

• UV-transparent coating for image sensors

  Image sensors as used in cell phones are partially color-blind. This is because of their coating, which prevents UV light from passing through. CMOS chips have as a result not been suitable for spectroscopy up to now. A new production process makes the coating transparent – and the sensors suita more

• Radio chip and sensor in one

  RFID technology is on the advance. But, up to now radio chips primarily supply data for the identification of products. Researchers have now developed a transponder which measures temperature, pressure and humidity. The chip with sensor function could revolutionize the applications market. »Special more

• Measuring particle size using modern laser diffraction techniques
  

  Many different techniques have been devised for determining particle size distribution, but for a wide range of industries laser diffraction has become the preferred choice. Laser diffraction, alternatively referred to as Low Angle Laser Light Scattering (LALLS), can be used for the non-destructive analysis of wet or dry samples, with particles in the size range 0.02 to 2000 micron and has inherent advantages which make it preferable to other options for many different materials. more
