Countless natural products and biologically active compounds incorporate indole and pyrrole heterocycles. Any method that makes it easy to introduce these moieties into complex structures would be a ...

Researchers in Germany have assessed direct coupling and integration between PV and batteries at the scale of a single PV module. They say their solution could be cheaper and provide superior ...

A group of researchers led by the Chinese Academy of Sciences (CAS) has developed a heat-driven thermoacoustic refrigerator/heat pump (HDTAR/HDTAHP) for high heating-temperature operation. They ...

Direct coupling is advantageous in many photodetector applications, such as viewing laser thresholds and modulation depth. I patented a very fast photodetector mount 1,2 in the early 1970s using these ...
