“…44,50 However, the NCT-1 sample showed a nickel peak with a blue shift at 260 nm from characteristic metallic nickel peak at 303 nm due to the less available nickel particles involved in SPR. 44,52 Even though NCT-2 and NCT-3 samples showed SPR behavior, the NCT-3 exhibited red shifts in wavelength due to the increased particles size due to the agglomeration. 44,51−53 Also, NCT-3 exhibited the peak at 270 nm related to the nickel metal, which deviated from the characteristic metallic nickel peak at 303 nm.…”

One of the important challenges in alkaline water electrolysis is to utilize a bifunctional catalyst for both hydrogen evolution (HER) and oxygen evolution (OER) reactions to increase the efficiency of water splitting devices for the long durable operations. Herein, nickel-cobalt-titanium (NCT) alloy is directly grown on a high corrosion resistance titanium foil by a simple, single, and rapid electrochemical deposition at room temperature. The electrocatalytic activity of NCT alloy electrodes is evaluated for both HER and OER in aqueous electrolyte. Our NCT electrocatalyst exhibits low overpotentials around 125 and 331 mV for HER and OER, respectively, in 1 M KOH. In addition to this outstanding activity, the bifunctional catalyst also exhibits excellent OER and HER electrode stability up to 150 h of continuous operation with a minimal loss in activity. Further, the NCT alloy directly grown on titanium foil is used to directly construct membrane electrode assembly (MEA) for alkaline electrolyte membrane (AEM) water electrolyzer, which make the practical applicability. This single-step electrodeposition reveals NCT on titanium foil with high activity and excellent electrode stability suitable for replacing alternative commercial viable catalyst for the alkaline water splitting.

“…The toxic effect of Ni(II) for human has been reported. Nickel could destroy the central nervous system, heart and kidneys, reduced the immunological capacity, eczema, and allergic [9,10]. As a consequence, the determination of these metals are required to assure the safety of milk and other dairy products.…”

Objective: The aim of this research was to validate inductively coupled plasma-atomic emission spectroscopy (ICP-AES) for quantitative analysis of cadmium (Cd), chromium (Cr), cuprum (Cu), mangan (Mn) and nickel (Ni) in milk products. Methods: The heavy metals in milk were determined using ICP-AES at optimized wavelength. The method was validated by assessing several validation parameters which included linearity and range, accuracy, precision and sensitivity expressed by the limit of detection and limit of quantification. The validated method was then used for the analysis of milks commercially available. Results: ICP-AES for determination of Cd, Cr, Cu, Mn, and Ni was linear over a certain concentration range with a coefficient correlation value of>0.997. The limit of quantification values of Cd, Cr, Cu, Mn, and Ni were 0.0047; 0.0050; 0.0066; 0.0061; and 0.0169 µg/ml, respectively. The precision of analytical method exhibited relative standard deviation (RSD) values of 3.18%; 4.17%; 3.05%; 2.93%; and 4.47% during repeatability test and 5.28%; 5.06%; 3.67%; 3.67%; and 11.17% during intermediate precision of Cd, Cr, Cu, Mn, and Ni respectively. The recoveries of these metals assessed using standard addition method were 92.25; 90.88; 102.87; 94.50; and 86.85%, respectively. Conclusion: ICP-AES offered a reliable and fast method for the determination of heavy metals in milk products. The developed method could be proposed as an official method for determination of heavy metals in milk products.

“…Also, extensive use of both the metals in pharmaceutical, electroplating, and paint industries increases its concentration in water, air, and soil [11]. Similarly, deficiency as well as excess of nickel is detrimental to animal and plant systems [12][13][14][15]. It has been known that the presence of nickel ions beyond a tolerable limit in drinking water (2.5 mg/mL) can cause disorders of the central nervous system, asthma, dermatitis, and cancer [16,17].…”

Abstract:Two receptor molecules N-(2-nitrophenyl)benzene-1,2-diamine (DPA) and N,N-bis(2-nitrophenyl)benzene-1,2-diamine (TPA) are proposed as Zn 2+ and Ni 2+ -selective electrodes, respectively. The two electrodes respond to Zn 2+ and Ni 2+ ions with the detection limits of 1.3 × 10 −6 M and 2.8 × 10 −6 M, respectively. Both the electrodes have a life time of four months and respond within 15 s and 20 s, respectively, for Zn 2+ and Ni 2+ over a wide pH range (3-9). The electrodes show very good selectivity towards the primary ions in presence of some alkali, alkaline earth, and transition metal ions.
