To enhance the electrocatalytic activity of anode catalysts used in alkaline-media direct methanol fuel cells(DMFCs), a Ni@Pd Pt electrocatalyst was successfully prepared using a three-phase-transfer method. The Ni@Pd Pt electrocatalyst was characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), transmission electron microscopy(TEM), and high-resolution TEM(HRTEM) techniques. The experimental results indicate that the average particle size of the core–shell-structured Ni@Pd Pt electrocatalyst is approximately 5.6 nm. The Ni@Pd Pt electrocatalyst exhibits a catalytic activity 3.36 times greater than that of Pd Pt alloys for methanol oxidation in alkaline media. The developed Ni@Pd Pt electrocatalyst offers a promising alternative as a highly electrocatalytically active anode catalyst for alkaline DMFCs.

As technology scales down, clock distribution networks(CDNs) in integrated circuits(ICs) are becoming increasingly sensitive to single-event transients(SETs).The SET occurring in the CDN can even lead to failure of the entire circuit system. Understanding the factors that influence the SET sensitivity of the CDN is crucial to achieving radiation hardening of the CDN and realizing the design of highly reliable ICs. In this paper, the influences of different sequential elements(D-flip-flops and D-latches, the two most commonly used sequential elements in modern synchronous digital systems) on the SET susceptibility of the CDN were quantitatively studied. Electrical simulation and heavy ion experiment results reveal that the CDN-SET-induced incorrect latching is much more likely to occur in DFF and DFF-based designs. This can supply guidelines for the design of IC with high reliability.

Vanadium battery has fast and large capacity charge and discharge characteristics, and the concentration and stability of the battery electrolyte are the key to the electrolyte performance. In actual, with higher acidity and higher concentration of the vanadium battery electrolyte, the ion-pair is dominant. The ion-pair dissociation constant is one of the important thermodynamic data related to battery performance. The vanadyl sulfate conductivity in aqueous solution was determined using the conductance method at 298.15K. Using the origin data fitting, the limiting molar conductance is obtained, and then by the improved Ostwald dilution law and the Davies equation, the activity coefficient is solved so as to obtain the ionic strength of the true solution. Using the Fuoss method, the dissociation constant of vanadyl sulfate ion-pair was calculated. At last, the vanadyl sulfate limiting molar conductance (Λ 0 ) is 174.8251748 S·dm2·mol?1, and the vanadyl sulfate ion-pair dissociation constant K d is 0.002636367, and then other thermodynamic properties can be studied.
