Pharmaceutical science researchers at Monash University in Australia, are using the FT4 universal powder tester from Freeman Technology to investigate novel techniques for improving the flow properties of excipients for inhaled product formulation. The team, led by Dr David Morton, has recently published work describing the use of optimised dry coating techniques to enhance the flow of fine lactose particles.
A Cornell researcher has created an extremely efficient transistor made from a material that may soon replace silicon as king of semiconductors for power applications.
University of Rochester optics professor Chunlei Guo made headlines in the past couple of years when he changed the color of everyday metals by scouring their surfaces with precise, high-intensity laser bursts.

Researchers from the University of Tours (INSERM U618) in France are using a Spraytec laser diffraction particle size analyzer from Malvern Panalytical to study nebuliser performance in real time. By understanding how aerosol concentration and droplet size vary during an inhalation cycle, the group expects to be able to develop new devices with better drug delivery characteristics.
Air Force Office of Scientific Research and National Science Foundation-funded professor, Dr. Xiang Zhang has demonstrated at the University of California, Berkeley the world's smallest semiconductor laser, which may have applications to the Air Force in communications, computing and bio-hazard detection.
As physicists strive to cool atoms down to ever more frigid temperatures, they face the daunting task of developing new, reliable ways of measuring these extreme lows. Now a team of physicists has devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a degree above absolute zero.
A team led by Yale University scientists has developed a way to rapidly manipulate and sort different cells in the blood using magnetizable liquids. The findings, which will be published the week of December 7 in the online edition of the Proceedings of the National Academy of Sciences, could dramatically improve the speed and sensitivity of tests used to detect cancer biomarkers, blood disorders, viruses and other diseases.
Nanoscale machines expected to have wide application in industry, energy, medicine and other fields may someday operate far more efficiently thanks to important theoretical discoveries concerning the manipulation of famo...
An ultra-high-resolution imaging technique using X-ray diffraction is a step closer to fulfilling its promise as a window on nanometer-scale structures in biological samples. In the Proceedings of the National Academy of Sciences, researchers report progress in applying an approach to "lensless" X-ray microscopy that they introduced one year ago.
Very often in science, the unexpected discovery turns out to be the most significant. Rice University Professor Junichiro Kono and his team weren't looking for a breakthrough in the transmission of terahertz signals,...
