Yolk–Shell Fe/Fe₄N@Pd/C Magnetic Nanocomposite as an Efficient Recyclable ORR Electrocatalyst and SERS Substrate

Wenling Jiao, Chen Chen, Wenbin You, Jie Zhang, more

Small > 15 > 7 > n/a - n/a

A yolk–shell Fe/Fe₄N@Pd/C (FFPC) nanocomposite is synthesized successfully by two facile steps: interfacial polymerization and annealing treatment. The concentration of Pd²⁺ is the key factor for the density of Pd nanoparticles (Pd NPs) embedded in the carbon shells, which plays a role in the oxygen reduction reaction (ORR) and surface‐enhanced Raman scattering (SERS) properties. The ORR and SERS...

Peiqing Long, Chen Chen, Dongfang Pang, Xitao Liu, more

Journal of the American Ceramic Society > 102 > 4 > 1741 - 1747

Nitrogen‐doped BaTiO₃ (BT) ceramics were produced by the solid‐state reaction method in conjunction with ammonia gas treatment. The optical absorption spectra results show that the bandgap of BT ceramic is narrowed after N‐doping, suggesting that the N‐doping is an effective route to increase light absorption. Polar properties measurements indicate that the ferroelectricity of BT ceramic is well maintained...

A novel control method to counteract the dynamical degradation of a digital chaotic sequence

Chen Chen, Kehui Sun, Yuexi Peng, Abdulaziz O. A. Alamodi

The European Physical Journal Plus > 2019 > 134 > 1 > 1-16

. Due to the finite computing precision, all orbits of a digital chaotic system fall into a cycle when this system is realized on digital computers and digital signal processors. To counteract this degradation, a dynamical perturbation-feedback mixed control (DPFMC) method is proposed by using a novel pseudorandom sequence. We choose a ciphertext sequence as the pseudorandom sequence, and it is used...
