In recent years, the application of lanthanide reagents in organic synthesis has been developed by leaps and bounds. Among them, many lanthanide reagents were found to have obvious selective catalysis in the reaction of carbon-carbon bond formation; at the same time, many lanthanide reagents were fo...
The rapid development in the fields of information and optoelectronics has promoted the continuous updating of chemical mechanical polishing (CMP) technology. In addition to equipment and materials, the acquisition of ultra-high-precision surfaces is more dependent on the design and industrial produ...
