Compact microscope a marvel

A compact microscope invented at Rice University is proving its potential to impact global health. This portable, battery-operated fluorescence microscope, which costs $240, stacks up nicely against devices that retail for as much as $40,000 in diagnosing signs of tuberculosis.

Two innovative LMU projects in physics receive EU funding

Two junior researchers at Ludwig-Maximilians-University (LMU) Munich have been awarded prestigious Starting Grants by the European Research Council (ERC). Professor Dieter Braun and Professor Philip Tinnefeld, both members of the Faculty of Physics, will each receive research funding in the amount of some 1.5 million Euros over the next five years.

Roller painting plastic solar cells

Solar cells that convert sunlight to electric power traditionally have been dominated by solid state junction devices, often made of silicon wafers. Thanks to nanotechnology, this silicon-based production technology has been challenged by the development of a new generation of solar cells based on thin film materials, nanocrystalline materials and conducting polymeric films. These offer the prospects of cheaper materials, higher efficiency and flexible features. Thanks to a highly efficient polymer solar cell fabrication method by a novel coating process - roller painting - even the mass production of polymer solar cells is now within reach. A particular advantage of roller painting compared to other coating processes is ease of control of the film thickness and uniformity.
