Developing renewable and clean energy systems for overall water electrolysis requires low-cost, highly efficient, and stable catalysts. With this motivation, nickel cobalt phosphorus (NiCoP) was electrodeposited onto nickel foam (NF) and then modified with graphitic carbon nitride (g-C3N4). The designed g-C3N4/NiCoP/NF electrode was used for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline water electrolysis. It exhibited a small overpotential of 80 mV@10 mA cm−2 with a Tafel slope of 89 mV dec−1 for the HER. It also exhibited an overpotential of 370 mV@10 mA cm−2 with a Tafel slope of 64 mV dec−1 for the OER. The g-C3N4/NiCoP catalyst exhibited satisfactory stability in an alkaline electrolyzer system, in which g-C3N4/NiCoP/NF was used as the anode and cathode. Meanwhile, the electrocatalyst requires only a cell voltage of 1.70 V to achieve 10 mA cm−2 current density for overall water electrolysis. [ABSTRACT FROM AUTHOR]

As children’s socialization changes, the areas on which parents’ attitudes focus also change. Middle childhood (age 7–11 years) is a special developmental period in which children experience changes in their physical, cognitive, and socialization aspects. However, few studies have investigated parental attitudes toward middle childhood. There are various measurement tools for parental attitudes. In our country, these tools are generally used to measure authoritative, authoritarian, and permissive dimensions, but not the overprotective dimension, which is the subject of an increasing number of studies. In Turkish literature, the only scale used to evaluate the overprotective dimension in addition to the authoritative, authoritarian and permissive dimensions is the Parent Attitude Scale (PAS). In this study, we aimed to evaluate whether PAS is a psychometrically adequate scale to measure the parental attitudes toward middle childhood. A total of 392 participants (260 mothers, 121 fathers, and 11 participants of unspecified gender) were included. Results of the confirmatory factor analysis revealed that a four-dimensional structure consisting of 42 items encompassing the authoritative, authoritarian, permissive, and overprotective dimensions was supported. Meanwhile, the results of the interdimensional correlation analysis showed that authoritative–authoritarian was negatively correlated to authoritative– permissive, while permissive–authoritarian was positively correlated to permissive–overprotective; no significant relationship was found with overprotective–authoritative. The results of the formal, metric, and scale invariance tests showed the applicability of PAS to both parents. Cronbach’s Alpha internal consistency coefficients, correlations between dimensions and test–retest results obtained within the scope of the reliability analysis also supported that the reliability level of the scale was at a desirable level. In conclusion, PAS is a valid and reliable scale applicable to parents with children aged 7–11 years. [ABSTRACT FROM AUTHOR]

The 4‐[5‐(undecylthio)‐1,3,4‐oxadiazol‐2‐yl)phenol (3)and 4‐(4‐(5‐(undecylthio)‐1,3,4‐oxadiazol‐2‐yl)phenoxy)phthalonitrile (5)were prepared viasubstitution reactions. Metallo‐phthalocyanines (6–9) were obtained by the cyclotetramerization of the phthalonitrile (5). The structures of novel compounds were verified using IR, 1H‐NMR, mass, UV‐Vis methods. Electrochemical characterization of synthesized MPcs (6–9)was carried out by the CV and SWV techniques in DCM/TBAP electrolyte. While MnClPc and CoPc complexes exhibited metal‐based and ring‐based reduction redox couples, CuPc and NiPc gave two ring‐based reduction redox couples. Spectroelectrochemical measurements were performed to observe the color transition during the reduction and oxidation reactions. Thus, the potentials of using the complexes as electrochromic materials were investigated. The CoPc gave the Q band at 667 nm with a shoulder at 663 nm. When the potential was applied to the cell, the intensity of Q band decreased with a shift in wavelength (from 667 nm to 663 nm). In addition, the natural turquoise color (x=0.2720, y=0.3366) of CoPc turned to greenish blue color (x=0.3080, y=0.3461). During the oxidation reactions, CuPc and NiPc gave ring‐based oxidation species. The intensity of Q bands decreased without shift. As a result of the in‐situ spectroelectrochemical measurements, it was observed that CuPc and NiPc, have sharper color transitions and have the potential to be used as electrochromic materials.
