The most recent developments in the synthesis and structure engineering of CeO2-encapsulated noble metal hybrids for catalytic applications are critically discussed.
The rational all-oxide TiC1-xOx@TiOy-TiO2 heterostructures with the significantly enhanced thermoelectric properties had been designed, and a high dimensionless figure of merit (ZT) value of up to 0.84 at 973 K was achieved in all-oxide TiC0.1O0.9@TiOy-TiO2 heterostructures.
Novel Cr3+-doped non-gallate near-infrared phosphorescent phosphor, Zn2SnO4: Cr, with the special optical characteristics of broad emission band (650–1200 nm, peaking at 800 nm) and long afterglow duration (>35 h) was presented, which successfully avoid the existing ubiquitous reliance on gallates as hosts in Cr3+-doped phosphorescent phosphors. This research also deals with the method of finely tailoring the local crystal field around the activator center, Cr3+, along with essential redeployment of trap distributions by adding Al. Indeed, such redeployment permits band gap adjustment and the dynamic variation of the annihilation and formation of defects.
A novel confinement-free synthesis of CP-HMNSFs possessing straight channels at fiber center surrounded by concentric short-pitch helical channels is discovered. The chloropropyl groups are found mainly located at central cylindrical part of the nanofibers. Helical PtCo nanowires with small and narrowly distributed radii of gyration are also fabricated, showing distinct ferromagnetic properties as compared with the straight counterparts.
