A series of hybrid Co Fe PBA（Prussian Blue Analogues） containing six different nitrogen heterocyclic, phen, 2,2’-bipy, 4,4’-bipy, phmz, quin and pyz, and corresponding PBA with Rb or Cs were synthesized by hierarchical diffusion method, precipitation titration method or hydrothermal method, respectively. The composition and structure of compounds were characterized by Energy dispersive spectroscopy（EDS）, ChN elemental analysis, Fourier transform infrared spectroscopy（IR） and X-ray powder diffraction（XRD）, respectively. And then, the electrochemical properties of these materials were studied by Cyclic Voltammetry and the influence of the organic ligands and alkali metals to cycle volt-ampere characteristic of the compounds were investigated. It is found that the Co Fe PBA containing quin shows significant improvement on the electrochemical performance. While with the introduction of Rb+ or Cs+, the electrochemical responses decrease greatly,which might be related to the structure transformation of the complexes.

In this study, a triple-component hydrazine sensor（PB@Ag/GF） was fabricated with freestanding graphite felt（GF）, silver nanoparticles（Ag） and Prussian Blue（PB）. The Ag nanoparticles were electrodeposited on GF ultrasonically（Ag/GF）, and rendered the catalyst of the chemical deposition of PB. The electrode was characterized by scanning election microscopy（SEM）, infrared spectroscopy（IR）, X-ray diffraction（XRD）, and energy-dispersive X-ray spectroscopy（EDS）. The electrochemical behavior of PB@Ag/GF was measured by cyclic voltammetry and amperometric measurements. The sensor displays a prominent electrocatalytic activity toward hydrazine oxidation, with a fast response time of 2 s, a low detection limit of 4.9 × 10-7 M and very high detection sensitivity of 26.06 A·M-1·cm-2.

hydroformylation could convert olefins and syngas （mixture of h2and CO） into aldehydes with a great atomic *** transformation serves as one of the most prominent processes in modern chemical industry, as it provides over 10million tons of aldehydes as feedstock for our daily essential products such as plasticizers, paints, solvents, and pharmaceuticals. This process generally requires efficient yet robust catalyst to realize decent efficacy. Compared with metals such as Co, Ru, and Pd, rhodium （Rh）-based catalysts stand out due to its superior activity even under mild reaction conditions, and dominate over 70%of global hydroformylation processes.

Peripheral nerve injuries induce a severe motor and sensory deficit. Since the availability of autologous nerve transplants for nerve repair is very limited, alternative treatment strategies are sought, including the use of tubular nerve guidance conduits(tNGCs). however, the use of tNGCs results in poor functional recovery and central necrosis of the regenerating tissue, which limits their application to short nerve lesion defects(typically shorter than 3 cm). Given the importance of vascularization in nerve regeneration, we hypothesized that enabling the growth of blood vessels from the surrounding tissue into the regenerating nerve within the tNGC would help eliminate necrotic processes and lead to improved regeneration. In this study, we reported the application of macroscopic holes into the tubular walls of silk-based tNGCs and compared the various features of these improved silk^(+) tNGCs with the tubes without holes(silk^(–) tNGCs) and autologous nerve transplants in an 8-mm sciatic nerve defect in rats. Using a combination of micro-computed tomography and histological analyses, we were able to prove that the use of silk^(+) tNGCs induced the growth of blood vessels from the adjacent tissue to the intraluminal neovascular formation. A significantly higher number of blood vessels in the silk^(+) group was found compared with autologous nerve transplants and silk^(–), accompanied by improved axon regeneration at the distal coaptation point compared with the silk^(–) tNGCs at 7 weeks postoperatively. In the 15-mm(critical size) sciatic nerve defect model, we again observed a distinct ingrowth of blood vessels through the tubular walls of silk^(+) tNGCs, but without improved functional recovery at 12 weeks postoperatively. Our data proves that macroporous tNGCs increase the vascular supply of regenerating nerves and facilitate improved axonal regeneration in a short-defect model but not in a critical-size defect model. This study suggests that further optimizatio
