Mini-Review

-Nanoparticles for CT Imaging. The development of nanoparticles (NP) provides new solutions to limitations of conventional contrast agents for X-ray computed tomography (CT) imaging. Lehui Lu (逯乐慧) and coworkers summarize the progress of NP-based CT contrast agents and provide an overview of multimodal imaging by integrating other imaging methods with CT, thus improving the precision and accuracy of diagnosis.

Communication

-Pd-catalyzed Aerobic Oxidation. For Pd-catalyzed aerobic oxidative reaction, direct oxidation of hydroquinone by air without a metal-macrocyclic electrontransfer mediator (ETM) was considered inefficient. Jan-E. Bäckvall, Man-Bo Li (李漫波)and coworkers report the first aerobic heterogeneous Pd-catalyzed allenic C–H arylation with catalytic amounts of benzoquinone without the need for an additional ETM.

-Organic Photovoltaics. Xiaozhang Zhu (朱晓张) and coworkers employ a convenient three-step synthetic route for all-fused-ring acceptors and obtain a new nonacyclic electron acceptor with extraordinary stability and promising performance. Based on a rational selection of electron-rich cores and electron-deficient terminals, a rich library of nonfullerene acceptors may be established for the application in organic photovoltaics.
