Vorgeschlagen wird ein System zur gravitativen Speicherung von Energie unter einer als hydraulischen Barriere (2) geeigneten Ton- oder Tonsteinschicht in einem Untergrund unter einer Geländeoberfläche, umfassend ein Spaltvolumen unter der Barriere mit ei...

The present invention provides a method to synthesize nanocomposites containing intercalated FeF- or FeO- nanoparticles in a graphitic carbon matrix by reaction of a volatile iron compound with a graphite fluoride (CF) or a graphite oxide (CO). The inventi...

The present invention relates to a composite solid polymer electrolyte which comprises a polymer, a plasticizer, a supporting electrolyte (salt), and a non-aqueous solvent. [0002] The present invention further relates to the use of the composite solid poly...

The present invention provides a new nanocomposite containing carbon-encapsulated transition metal oxide nanoparticles with a core-shell structure, wherein the transition metal oxide core has a diameter from 5 nm to 50 nm which is covered by a graphitic co...

Computing distance tables is important for many logistics problems like the vehicle routing problem (VRP). While shortest distances from all source nodes in S to all target nodes in T are time-independent, travel times are not. We propose a method of deter...
