摘要： Durable nanoporous nanostructured materials that modify, eliminate and destroy biofilms that may develop due to the presence of bacteria, fungi and other microbes and method for making the same. Such nanoporous nanostructures may be deposited as coatings on a substrate and such coatings may include at least one nanopore and a plurality of nanoparticles which adhere to the substrate and/or other particles. The nanostructure can be produced using a single-sided electrode arrangement, which is configured to produce an electrical arc or discharge at one end of an electrode and to emit the nanoparticles from the electrode, where the arc or discharge can be produced without the end of the electrode being in proximity to a grounded object. The nanoparticles form a non-porous framework which delineates any nanopores and which can be deposited as one or more layers of nanothickness. Such nanostructures may be resistant to removal from the substrate. Also described are testing methods and apparatus for the quick, accurate and simple evaluation of the efficacy of the antibiofilm properties of the nanoporous nanostructure.

摘要： A component of an aluminium production cell, in particular a cathode or a cell lining of an electrolytic cell for the production of aluminium by the electrolysis of alumina in cryolite, having an aluminium-wettable refractory coating on a heat-stable baked carbon-containing body, is produced from a part-manufactured cell component which is a layered composite of two precursors. A precursor layer of the aluminium-wettable refractory coating contains at least one aluminium-wettable refractory material in particulate form, or a particulate micropyretic reaction mixture which when ignited reacts to form at least one aluminium-wettable refractory material, or a mixture thereof, and non-carbon fillers and binders. A non-baked or part-baked precursor of the heat-stable carbon-containing body comprises particulate carbon compacted with a heat-convertible binder which when subjected to heat treatment binds the particulate carbon into the heat-stable carbon-containing body of the fully-manufactured cell component. This layered composite is convertible to the fully-manufactured cell component by heat treatment to form the aluminium-wettable refractory coating and simultaneously bind and heat-stabilize the carbon-containing body.

摘要： To improve its resistance to penetration and degradation by sodium, a carbon cathode for use in aluminium production by the electrolysis of alumina dissolved in a cryolite-based molten electrolyte is pretreated with a solution, suspension or melt of a lithium compound. This pre-treatment takes place prior to, during or after forming the cathode but before use thereof. The entire carbon cathode, or only that part of the carbon which is nearest to the active cathode surface is treated, making it more resistant to penetration by components of the molten electrolyte of aluminium.
