We report the successful fabrication of a micro-pseudocapacitor based on ternary nickel cobalt sulfide for the first time, with performance substantially exceeding that of previously reported micro-pseudocapacitors based on binary sulfides. The CoNi2S4 micro-pseudocapacitor exhibits a maximum energy density of 18.7 mW h cm(-3) at a power density of 1163 mW cm(-3), and opens up an avenue for exp...

The cobalt phenylthiolate complex, cis,mer-(PMe3)3Co(CH3)2SPh, was found to undergo competitive two-electron ethane reductive elimination and C-H bond cyclometallation. The thiophenolato bound cobaltacycle was generated via C-H bond oxidative addition to a five-coordinate intermediate followed by rapid methane elimination. A related cobalt isothiocyanate complex, cis,mer-(PMe3)3Co(CH3)2NCS, was...

Processes for recycling lithium ion batteries (LIB), in particular complex chemistries such as those containing nickel-manganese-cobalt oxide (NMC) cathodes are hindered by tradeoffs between capital cost, process sustainability, and materials recovery. Most metal separations primary secondary production of critical elements rely on anion exchange chemistries. Herein, we explore the application ...

Inorganic nanocrystals have attracted widespread attention both for their size-dependent properties and for their potential use as building blocks in an array of applications. A complete understanding of chemical transformations in nanocrystals is important for controlling structure, composition, and electronic properties. Here, we utilize in situ high-resolution transmission electron microscop...

By WILLIAM KERPPOLA, M.I).* P HOSPHATASE can be demonstrated in tissues by means of reliable histochemical methods. Such a method! w’as described for alkaline phosphatase in 1939 by Gomori,#{176}’ and in the same year by Takamatsu.2 Two years later Gomori#{176} described his method for demonstrating acid phosphatase. The principle on which these methods are based is to incubate slices of tissue...

High energy and power densities are the greatest challenge for all-solid-state lithium batteries due to the poor interfacial compatibility between electrodes and electrolytes as well as low lithium ion transfer kinetics in solid materials. Intimate contact at the cathode-solid electrolyte interface and high ionic conductivity of solid electrolyte are crucial to realizing high-performance all-so...

We have fabricated highly efficient CdS/CdSe quantum dot-sensitized solar cells (QDSSCs) featuring low-cost cobalt sulfide (CoS) counter electrodes. Under 100 mW cm(-2) irradiation, the CdS/CdSe QDSSC featuring a CoS electrode provided an energy conversion efficiency as high as 3.4%.
