A recent study has evaluated frameworks and tools used in Europe to assess the potential health and environmental risks of manufactured nanomaterials. The study identifies a trend towards tools that provide protocols for conducting experiments, which enable more flexible and efficient hazard testing.
Researchers have shown how to prevent the absorption loss of ultrathin CIGSe cells. They designed nanostructured back contacts for light trapping and could achieve a new record value of the the short circuit current density reaching nearly the best values for thicker CIGSe-cells.
Researchers have developed a technique to visualize, for the first time, the complete evolution of micro- and nanoscale structural formation on a material's surface, both during and after the application of a laser pulse.
The analysis of the minutest quantities of pharmaceutical samples is of crucial importance for the research and synthesis of new medications. At the moment it represents a technical challenge, but a new infrared method of measurement may remedy this.
