Although alloy tin plating has been known and used for many years, this paper will describe the use of a new non-cyanide tin/zinc alloy as a possible replacement coating for cadmium and the use of a tin/nickel alloy as a possible substitute for barrel decorative chromium plating. A review on the corrosion properties of tin, zinc and cadmium compared to tin/zinc alloys and review of the properti...

Genetic modification of shoot and root morphology has potential to improve water and nutrient uptake of wheat crops in rainfed environments. Near-isogenic lines (NILs) varying for a tillering inhibition (tin) gene and representing multiple genetic backgrounds were phenotyped in contrasting, controlled environments for shoot and root growth. Leaf area, shoot and root biomass were similar until t...

The main objective of this work was to design an innovative method prepare heterogeneous heteropolyacid catalysts. H3PW12O40 (HPW) modified with tin(II) by two methodologies: a conventional aqueous ion-exchange (CS) and redox solid-state (SS). In both cases, Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD) measurements evidenced that Keggin structure preserved. All materia...

Terrain information is implied in airborne LIDAR data, therefore algorithms should be developed to extract meaning information from them for subsequent application. Especially the building roofs in airbore LIDAR data are very important for 3-D building reconstruction. The difficulty of building roof extraction lies on how to exclude the irrelevant data and to exact them automatically. Therefore...

The preparation of 2D-layered C@TiN: Ti3C2 MXenes were synthesized via the previous reported paper. Typically, 1 g Ti3AlC2 (purchased from FORSMAN Company, China) was added into 15 mL 40% HF solution. The solution was stirred for 120 h at 40 oC. After the HF etching, the material was centrifuged and washed in deionized water until pH~7. The Ti3C2 MXene was obtained after drying at 50 oC for 12h...

The microstructure and magnetic properties of the FePt films grown on large mismatched ZrN (15.7%) intermediate layer were investigated. With using ZrN intermediate layer, FePt 10 nm films exhibited (001) texture except for some weaker FePt (110) texture. Good epitaxial relationships of FePt (001) <100>//ZrN (001) <100>//TiN (001) <100> among FePt and ZrN/TiN were revealed from the transmission...

Work reported in recent years from this laboratory has outlined the general features of poisoning in animals given diand trialkyl tin salts (Stoner, Barnes, and Duff, 1955). More detailed accounts of the cerebral oedema produced by triethyl tin in rats (Magee, Stoner, and Barnes, 1957) and the bile duct and liver lesions produced by dibutyl tin salts in rats and mice have also been prepared (Ma...

Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA. Here, routes to PTA starting from oxidized products of 5-hydroxymethylfurfural (HMF) that can be produced from biomass are reported. These routes involve Diels-Alder ...
