The work is based on the use of a 'continuous flow' microreactor to produce nanoparticle inks that make solar cells by printing. Existing approaches based mostly on batch operations are more time-consuming and costly.
The clever thing about the technique is that researchers can target selected cells without harming surrounding tissue. There are many ways to kill cells, but this method is contained and remote-controlled.
A novel ultrathin collagen matrix assembly allows for the unprecedented maintenance of liver cell morphology and function in a microscale 'organ-on-a-chip' device that is one example of 3D microtissue engineering.
A new type of biomolecular tweezers could help researchers study how mechanical forces affect the biochemical activity of cells and proteins. The devices - too small to see without a microscope - use opposing magnetic and electrophoretic forces to precisely stretch the cells and molecules, holding them in position so that the activity of receptors and other biochemical activity can be studied.
Die Deutsche Gesetzliche Unfallversicherung (DGUV) hat das neue Arbeitsschutz-Nano-Portal offiziell vorgestellt. Das Portal bietet aktuelle Informationen zur Arbeitssicherheit und neuartige, interaktive E-Learning Tools, die 'Nanoramen'.
Targeting a desired color for a white light-emitting diode is like spraying a savannah with buckshot in the hope of fortuitously downing a well-hidden deer. Scientists at the University of Twente and Philips have reached an understanding of the transport of light in white LEDs in physical terms.
A new approach to studying solar panel absorber materials has been developed by researchers in France. The technique could accelerate the development of non-toxic and readily available alternatives to current absorbers in thin film based solar cells.
