Abstract: Li or Na based battery having an anode (or current collector) at least partially covered on its side facing the electrolyte by at least one artificial solid-electrolyte interphase layer with at least one layer of porous graphene of a thickness of less than 25 nm with pores having an average characteristic width in the range of 1-1000 nm.

Abstract: Method and apparatus for producing filamentary structures. The structures include single-walled nanotubes. The method includes combusting hydrocarbon fuel and oxygen to establish a non-sooting flame and providing an unsupported catalyst to synthesize the filamentary structure in a post-flame region of the flame. Residence time is selected to favor filamentary structure growth.

Abstract: A method for generating a chemically bonded organic functionality on the surface of particles or for condensing an organic compound onto the particle surface giving an organic coating is described. The method comprises a step of contacting a vapour containing an organic compound and a gaseous process stream containing flame-generated particles so as to react the organic compound with surface groups on the particles to give a chemically bonded organic functionality to the particle surface or so as to result in an organic coating.

Abstract: An apparatus for flow rate measurement includes a body having a chamber with an inlet and an outlet and a structure, buoyant in the presence of a fluid, disposed in the chamber. The structure moves to a position in the chamber in proportion to a flow rate of the fluid flowing from the inlet to the outlet.

Abstract: The apparatus for flow rate control of a fluid provides a roller clamp having either a clamp body with a non-linear clamp body surface or a clamp body with a non-linear adjustment roller track, which, when coupled to a tube, provides a linear, or otherwise pre-determined, relationship between flow rate of a fluid flowing through the tube and adjustment of the roller clamp.

Abstract: A clamp having a first clamp body, a second clamp body, and a clamping structure coupled to at least one of the first and second clamp bodies. One or both of the clamp bodies form a channel adapted to receive a tube. The clamping structure is movable in the channel to control the flow rate of a fluid flowing through the tube. In one embodiment, the clamp is provided as a rotary clamp having clamp bodies that are adapted to be rotated relative to each other to control the flow rate of a fluid through a tube disposed in the rotary clamp. The rotary clamp has a substantially linear, or otherwise pre-determined, relationship between flow rate of a fluid flowing through the tube and rotation of the second clamp body.
