Abstract: Improved negative electrodes can comprise a silicon based active material blended with graphite to provide more stable cycling at high energy densities. In some embodiments, the negative electrodes comprise a blend of polyimide binder mixed with a more elastic polymer binder with a nanoscale carbon conductive additive. The silicon-based blended graphite negative electrodes can be matched with positive electrodes comprising nickel rich lithium nickel manganese cobalt oxides to form high energy density cells with good cycling properties.

Abstract: Embodiments may take the form of a perforating gun of modular assembly. The perforating gun may include at least one centralizing member at an interface between a loading tube and a carrier. Among modular components, the gun may also include an initiator assembly module that is electrically coupled to a modular feedthrough with a connector. The insert and the centralizing member may enhance axial cohesiveness of the modular gun. A shock absorbing mount may be located within the carrier and may receiving the initiator assembly module to provide added axial cohesiveness to the modular gun.

Abstract: The present invention relates to the field of industrial processes for measuring sugars and starch in cells and concerns the process of functionalising synthesized gold nanoparticles functionalized with polymer ligands, for the selective measurement of sucrose or starch in intracellular fluid. Also disclosed is a nanocompound for measuring the concentration of sucrose or starch in intracellular fluid, which contains synthesized gold nanoparticles functionalized with polymer ligands.

Abstract: A centrifugal separator for separating a liquid phase from crankcase gases of an internal combustion engine includes a separation chamber, a rotor shaft, a rotor inside the separation chamber, an inlet for crankcase gases, a gas outlet, and a liquid outlet for separated liquid phase. The centrifugal separator also includes a liquid outlet chamber, a check valve, and a rotating member. The liquid outlet chamber forms an individual chamber and is arranged in fluid communication with the separation chamber via a liquid passage. The rotating member is connected to the rotor shaft and is arranged inside the liquid outlet chamber. The liquid outlet forms an outlet of the liquid outlet chamber. The check valve is arranged in the liquid outlet.

Abstract: An arrangement for cleaning gas includes a centrifugal separator and pre-separation unit. The centrifugal separator includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas from the pre-separation unit, a rotating stack of separation disks, a gas outlet and a drainage outlet for discharging separated liquid impurities. The pre-separation unit is arranged upstream of said inlet of said centrifugal separator, and it comprises a pre-separation inlet having a cross-sectional area A2 and permitting supply of the gas to be cleaned. A2 is larger than the cross-sectional area A1 of the inlet to the separation space of the centrifugal separator. A pre-separation outlet permits supply of gas from the pre-separation unit to the gas inlet of the centrifugal separator.

Abstract: A composite coated form of lithium cobalt oxide is described that can achieve improved cycling at higher voltages. Liquid phase and combined liquid and solid phase coating processes are described to effectively form the composite coated powders. The improved cycling positive electrode materials can be effectively combined with either graphitic carbon negative electrode active materials or silicon based high capacity negative electrode active materials. Improved battery designs can achieve very high volumetric energy densities in practical battery formats and with reasonable cycling properties.
