“…Strongly pronounced Ni 2 p doublet peaks of Ni 2 p 1/2 and Ni 2 p 3/2 were detected in the 850–890 eV region of the spectrum of the KOH-treated substrate, compared with the untreated substrate. Similar to the chemical shift to higher binding energy, as observed for the Ti 2 p peak in the KOH-treated TAV substrate, the main Ni 2 p peak also shifted to a higher binding energy of 854.9 and 874.5 eV due to the Ni–O bond formed, leading to the oxidation state of Ni 2+ and Ni 3+ [48,49,50,51]. This means that Ni oxide components coexist in the obtained oxide film, unlike the TAV substrates where the alloying species of Al and V are released during the KOH treatment.…”

Nanostructured potassium-incorporated Ti-based oxides have attracted much attention because the incorporated potassium can influence their structural and physico-chemical properties. With the aim of tuning the structural and physical properties, we have demonstrated the wet corrosion process (WCP) as a simple method for nanostructure fabrication using various Ti-based materials, namely Ti–6Al–4V alloy (TAV), Ti–Ni (TN) alloy and pure Ti, which have 90%, 50% and 100% initial Ti content, respectively. We have systematically investigated the relationship between the Ti content in the initial metal and the precise condition of WCP to control the structural and physical properties of the resulting nanostructures. The WCP treatment involved various concentrations of KOH solutions. The precise conditions for producing K-incorporated nanostructured titanium oxide films (nTOFs) were strongly dependent on the Ti content of the initial metal. Ti and TAV yielded one-dimensional nanowires of K-incorporated nTOFs after treatment with 10 mol/L-KOH solution, whereas TN required a higher concentration (20 mol/L-KOH solution) to produce comparable nanostructures. The obtained nanostructures revealed a blue-shift in UV absorption spectra due to the quantum confinement effects. A significant enhancement of the photocatalytic activity was observed via the chromomeric change and the intermediate formation of methylene blue molecules under UV irradiation. This study demonstrates the WCP as a simple, versatile and scalable method for the production of nanostructured K-incorporated nTOFs to be used as high-performance photocatalysts for environmental and energy applications.

“…The Ni-rich Ti–Ni-based alloys are favored by researchers of engineering materials, functional materials, and biomedical alloys, based on high strength, low density, superelasticity, and shape memory properties [1,2,3,4,5]. These excellent properties enable Ti–Ni-based shape memory alloys (SMAs) to be a functional material which integrates sensing and driving [6,7]. The applications of Ti–Ni-based SMAs mainly include microelectromechanical systems and novel medical devices [6,7].…”

The martensitic transformation and superelasticity of Ti49Ni51 shape memory alloy heat-treatment at different temperatures were investigated. The experimental results show that the microstructures of as-cast and heat-treated (723 K) Ni-rich Ti49Ni51 samples prepared by rapidly-solidified technology are composed of B2 TiNi phase, and Ti3Ni4 and Ti2Ni phases; the microstructures of heat-treated Ti49Ni51 samples at 773 and 823 K are composed of B2 TiNi phase, and of B2 TiNi and Ti2Ni phases, respectively. The martensitic transformation of as-cast Ti49Ni51 alloy is three-stage, A→R→M1 and R→M2 transformation during cooling, and two-stage, M→R→A transformation during heating. The transformations of the heat-treated Ti49Ni51 samples at 723 and 823 K are the A↔R↔M/A↔M transformation during cooling/heating, respectively. For the heat-treated alloy at 773 K, the transformations are the A→R/M→R→A during cooling/heating, respectively. For the heat-treated alloy at 773 K, only a small thermal hysteresis is suitable for sensor devices. The stable σmax values of 723 and 773 K heat-treated samples with a large Wd value exhibit high safety in application. The 773 and 823 K heat-treated samples have large stable strain–energy densities, and are a good superelastic alloy. The experimental data obtained provide a valuable reference for the industrial application of rapidly-solidified casting and heat-treated Ti49Ni51 alloy.

In this study, one pot synthesis of nickel nanoparticles immobilized on reduced graphene oxidebranched polyethyleneimine (NiNPs@rGO-bPEI) aerogel is reported. To produce graphene-based supramolecular hydrogel, bPEI with a high density of amine groups was used as a cross-linking agent. The simultaneous co-reduction of GO and nickel ions was carried out using sodium borohydride (NaBH 4 ). The catalytic activity of the NiNPs@rGO-bPEI aerogel was investigated for hydrogen generation from the hydrolysis of NaBH 4 at room temperature. The effect of various amounts of bPEI as the linking agent on the structure of the aerogel product was investigated. Moreover, the influence of various amounts of nickel loading on the catalytic activity of NiNPs@rGO-bPEI was also studied. The ease of synthesis (only at one step), low cost, being environmentally benign, existence of nitrogen and nickel to have interaction with molecular hydrogen, and also the large surface area are the key features of the synthesized catalyst that makes it suitable for industrial applications.
