TL;DR: In this paper, a nano titanium dioxide photo-catalyst was used to achieve a cross-linking finish on the bleached cotton fabric by using a nano TiO2 photocatalyst which can effectively operate under UV irradiation.
Abstract: The present research attempts to accomplish a cross-linking finish on the bleached cotton fabric by using a nano titanium dioxide photo-catalyst which can effectively operate under UV irradiation. In this study, the bleached cotton fabrics were treated with two cross-linking agents including 1,2,3,4-butane tetracarboxylic acid (BTCA) and citric acid (CA) in the presence of sodium hypophosphite (SHP) and nano TiO2 (NTO) and then, cured at three different conditions: UV irradiation (UV), High temperature (High temp) and a combination of UV and high temperature (UV–Temp). In addition, the bending length, yellowness index, wet and dry crease recovery angle, tensile strength retention (%) and water drop absorption time of treated samples were evaluated. Also, treated cotton fabrics and NTO were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX) and X-ray Diffraction (XRD). The results show that samples treated with BTCA have higher values of dry crease recovery angle (DCRA) as compared with samples treated with CA. It was also found that DCRA values are higher for samples treated under UV–High temp condition than samples treated under UV or High temp condition alone. Nevertheless, yellowness indexes with BTCA were lower than CA and tensile strengths retention (%) with CA were higher than BTCA.

TL;DR: In this article, a novel flame-retardant for woven cotton fabric using sodium hypophosphite (SHP), maleic acid (MA), triethanol amine (TEA), and nano TiO2 through conventional pad-dry-cure method was employed to investigate the thermal decomposition behavior of the treated samples.

TL;DR: In this paper, a ternary nanoalloy for ethanol oxidation reaction (EOR) in alkaline media is synthesized in a simple aqueous bath containing Pd(II) and Ni(II), with sodium hypophosphite as reducing agent and sodium citrate as the complexing agent.
Abstract: Carbon-supported well-dispersed PdeNieP ternary catalyst targeted for ethanol oxidation reaction (EOR) in alkaline media is synthesized in a simple aqueous bath containing Pd(II) and Ni(II) salts with sodium hypophosphite as the reducing agent and the source for P and sodium citrate as the complexing agent. XRD analysis on the as-prepared PdeNieP/C reveals that Ni shrinks while P expands the Pd lattice structure, and XPS measurement suggests different electronic effects of the two alloying elements on Pd. Cyclic voltammetry and chronoamperometry indicate that the PdeNieP/C presents a remarkably higher electrocatalytic activity than the state-of-the-art Pd/C, PdeP/C and PdeNi/C catalysts. This may be ascribed to the unique electronic, geometric and bifunctional effects involved in this ternary nanoalloy. 2013 Elsevier B.V. All rights reserved.

TL;DR: In this article, the phase transformation temperature was independent of the phosphorus content, whereas the texture approached the random orientation with increasing phosphorus content in the Ni-P solid-solution grains.
Abstract: Electroless Ni-7.4 to 10% P deposits obtained from acidic nickel sulphate baths with sodium hypophosphite as a reducing agent were analysed by transmission electron microscopy, X-ray diffraction and thermal analysis. The deposits could be represented better by a microcrystalline structure composed of 4 to 5 nm fcc Ni-P solid-solution grains rather than an amorphous structure. The deposits also had the (111) texture, which persisted in nickel grains even after phase separation of nickel and Ni3P by heating in the case of the low nickel content, whereas the texture approached the random orientation with increasing phosphorus content. The phase transformation temperature was independent of the phosphorus content.
