The following patent explains Francesco Celani’s method for preparing his Ni-coated wires (and other forms) to better adsorb hydrogen. I cannot be certain this is the state of the art as used to process the materials in the recent NI and ICCF-17 demos but I notice a number of potential replicators requesting information on this subject and thought it worthy of bringing to your attention. He cleverly uses the term cold fusion in his patent by relating the invention to a tool for cf research. Now, surely no-one could object to that.
Abstract: Thin nano structured layers on surfaces of nickel or its alloys for quickly achieving high hydrogen adsorption values (H/Ni˜0.7) through direct metal/gas contact. The said layers are produced by a process comprising the step of oxidising the said surfaces, applying a film of aqueous silica sol to them, subsequent heating in an -oxidising atmosphere and final activation through reduction in a reducing atmosphere. …
He gives two examples – the second of which describes preparing wire:
Five 99.5% nickel wires (each of diameter 200 μm, length 200 cm, lateral surface area 12.5 cm2, overall weight of the 5 wires 2.7952 g) were each treated in the following way: a) degreasing in 2M NaOH at 70° C.; washing in distilled H2O; washing in acetone; final wash in distilled H2O and drying in hot air. b) each wire was heated to a temperature of approximately 1000° C. by Joule heating in air for a time of 400 seconds. The temperature was estimated by the change in the resistance of the wire. c) after cooling each wire was coated with a solution of colloidal silica (30% by weight of SiO2, sol dimensions 12 nm) in three passes with a brush. d) each wire treated in this way was heated by Joule heating as in b). After cooling 5 wires were weighed again; an overall increase in weight of approximately 1.2 mg was recorded. e) 20 ml of 85% by weight H3PO4, 100 ml of a 20% by weight solution of PdNO3 and 100 ml of a 20% by weight solution of NiNO3 were added to the colloidal silica solution (100 cm3). f) the five wires were treated with the solution mentioned in e) using the means described in c). g) finally the wires were heated by Joule heating as in b). After cooling the increase in weight in comparison with the bare wire was found to be approximately 2.3 mg. h) the five wires, each inserted into a quartz-fibre sheath 0.2 cm in diameter and bent appropriately were placed in a cylindrical gas-tight stainless steel container (volume 2025 cm3) fitted with pressure and temperature sensors and held at a temperature of 150° C. i) after vacuum had been applied hydrogen was quickly introduced into the container until it reached a pressure of 5 bar; the temperature of the container was held at 150° C. The Ni wire adsorbed hydrogen until it reached saturation in approximately 500 seconds; the H/Ni atomic ratio produced from the change in pressure was estimated to be 0.65. l) the container containing the wire was evacuated and filled with air at ambient pressure; the temperature of the container was held at 100° C. in order to evaluate the discharge time for the wire. It was surprisingly found that after 600 hours the Ni wire retained its hydrogen content almost unchanged.
