A barrier metal is a material used in integrated circuits to chemically isolate semiconductors from soft metal interconnects, while maintaining an electrical connection between them. For instance, a layer of barrier metal must surround every copper interconnect in modern integrated circuits, to prevent diffusion of copper into surrounding ...
Diffusion-limited aggregation (DLA) is the process whereby particles undergoing a random walk due to Brownian motion cluster together to form aggregates of such particles. . This theory, proposed by T.A. Witten Jr. and L.M. Sander in 1981, [1] is applicable to aggregation in any system where diffusion is the primary means of transport in the sy
Lithium is especially useful, because its ions can be arranged to move between the anode and the cathode, using an intercalated lithium compound as the cathode material but without using lithium metal as the anode material. Pure lithium will instantly react with water, or even moisture in the air; the lithium in lithium-ion batteries is a less ...
Rechargeable lithium metal batteries are secondary lithium metal batteries.They have metallic lithium as a negative electrode.The high specific capacity of lithium metal (3,860 mAh g −1), very low redox potential (−3.040 V versus standard hydrogen electrode) and low density (0.59 g cm −3) make it the ideal negative material for high energy density battery technologies.

A longtime hairdresser at Fox Sports has sued the company, alleging that she was fired after raising a series of concerns about workplace misconduct, and after repeatedly refusing to have sex with ...
Kawhi Leonard is apparently close to being ready to make his season debut with the Los Angeles Clippers. Leonard practiced with the team for the first time this season Tuesday, head coach Ty Lue ...
Supreme Court Chief Justice John Roberts slammed what he described as “dangerous” talk by some officials about ignoring federal court rulings, using an annual report weeks before President ...
Beyond aperiodicity, these structures are used because the porous structure allows for rapid diffusion throughout the material, and the porous structure provides a large reaction surface. Fabrication is through coating the ambigel with a polymer electrolyte and then filling the void space with RuO 2 colloids that act as an anode.
