TL;DR: In this article, the effects of corroded method of AlN ceramic and components of electroless plating solution were investigated, and it was found that the perfect surfaceness was obtained by 70 min soaked in 500 g·L-1 NaOH solution.
Abstract: In this paper,nickel films were deposited on AlN ceramic by electroless plating.The effects of corroded method of AlN ceramic and components of electroless plating solution were investigated.It was found that the perfect surfaceness of AlN ceramic was obtained by 70 min soaked in 500 g·L-1 NaOH solution.The addition of SDS(Sodium dodecyl sulfate) improves the uniformity of the coatings.Brazing experiments of AlN ceramic and SiCp/Al composite material were used to test the quality of the nickel coating,and the shearing strength can reach to 110 MPa.

TL;DR: In this article, a mixt. of a metal salt such as NiSO4, a complexing agent such as sodium citrate and a reducing agent is used to obtain a Ni plated film of high purity.
Abstract: PURPOSE:To increase plating speed and obtain a Ni film of high purity by using a mixt. of a specific amt. of a hydrogen boride cpd. and hydrazine as a reducing agent contained in the title plating soln. consisting of a metal salt such as NiSO4, a complexing agent such as sodium citrate and the reducing agent. CONSTITUTION:In the title plating soln. consisting of a metal salt such as NiSO4, a complexing agent such as sodium citrate and a reducing agent, a mixt. of below 5 cc/l of a hydrogen boride cpd. such as diethyl (methyl)borazane and 5-100 cc/l of hydrazine is used as the reducing agent. By this method a Ni plated film of such a high purity as above 97% is obtd., the plating speed is increased, and the ratio of impurities and the plated component are always stabilized.

TL;DR: In this article, a weakly crystallized α-form of iron(III) hydroxide was synthesized and its structure-related and adsorption properties were determined for removing chromium(VI) from industrial waste water.
Abstract: Weakly crystallized α-form of iron(III) hydroxide was synthesized. Its structure-related (the specific surface area, the dominant pore radius, and the total pore volume) and adsorption (the dynamic exchange capacity with respect to chromium(VI)) characteristics were determined. Experiments aimed at the selection of modifying additives increasing the mechanical strength of iron(III) hydroxide were carried out. It was shown that adsorbents modified simultaneously with nickel(II), cobalt(II), zinc, and aluminum have a mechanical strength enough for their use in industrial adsorption units. An economical method was developed for the synthesis of mechanically strong iron(III) hydroxide-based adsorbent for removing chromium(VI) from industrial waste water. The adsorbent can be synthesized from spent solutions used for printed-circuit boards or steel etching or for electroless nickel plating.

TL;DR: The nickel sealed double-coated optical fiber as mentioned in this paper is constructed from the double-covered optical fiber sealed with a nickel layer that is fabricated using electroless plating, which exhibits good electrical conductivity, high mechanical strength, high resistance to moisture attack and microbending insensitivity.
Abstract: The nickel sealed double-coated optical fiber is constructed from the double-coated optical fiber sealed with a nickel layer that is fabricated using electroless plating. The nickel sealed double-coated optical fiber exhibits good electrical conductivity, high mechanical strength, high resistance to moisture attack and microbending insensitivity. Moreover, the external damage protection, abrasion resistance, adhesion, toughness and stripping force of coatings fit the fiber requirement. As the nickel film thickness is 68 nm, the fiber has the excellent ability to sustain thermal loading. Nickel sealed double-coated optical fibers are superior to conventional double-coated optical fibers and hermetically coated optical fibers for use as optical transmission lines.
