Quantitative analysis of the precipitates of the steel is necessary in order to improve mechanical properties of the steel, because the precipitates in steels play an important role on the grain growth, recrystallization, and precipitation hardening. Recently, in-situ scanning electron microscope(SEM) observations on the precipitates with potentiostatic etching method in non-aqueous electrolyte have been reported. We applied the potentiostatic etching method for the preparation of the extraction replica.

First Time

The Ni-MOF as co-catalyst has been in-situ introduced on the surface of ZnO photoelectrode by chemical etching method for the first time, and the unique organic/inorganic heterostructure (Ni-MOF/ZnO) was applied for photoelectrochemical water splitting. The Ni-MOF could work as special co-catalyst to improve the kinetic and charges separation of ZnO electrode, and the photocurrent density of Ni-MOF/ZnO has increased to about 1.8 times than that of bare ZnO. The IPCE value of Ni-MOF/ZnO has been enhanced up to 11% (355[Formula: see text]nm, 0.5[Formula: see text]V vs Ag/AgCl). The proposed mechanism of charges transfer has been also discussed in-depth, according to the photoelectrochemical performance.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
