How Does Our Voice Reflect Who We Are? Connecting the Voice and the Self Using Implicit Association Tests.

Purpose: This study examined the contribution of voice to the self via implicit associations.

Method: An implicit association test (IAT) of the voice and the self was created and presented to vocal performers and community controls. One-hundred eleven participants completed this voice-self IAT, the Vocal Congruence Scale (VCS), and the Voice Handicap Index (VHI) via an in-person, monitored, and timed Qualtrics survey.

Influence of Annealing Temperature on the OER Activity of NiO(111) Nanosheets Prepared via Microwave and Solvothermal Synthesis Approaches.

Earth-abundant transition metal oxides are promising alternatives to precious metal oxides as electrocatalysts for the oxygen evolution reaction (OER) and are intensively investigated for alkaline water electrolysis. OER electrocatalysis, like most other catalytic reactions, is surface-initiated, and the catalyst performance is fundamentally determined by the surface properties. Most transition metal oxide catalysts show OER activities that depend on the predominantly exposed crystal facets/surface structure.

Application of Ion Chromatography for the Reliable Quantification of Ammonium in Electrochemical Ammonia Synthesis Experiments: A Practical Guide.

Assessing novel electrocatalysts for the electrochemical ammonia synthesis (EAS) requires reliable quantitative trace analysis of electrochemically produced ammonia to infer activity and selectivity. This study concerns the development of an ion chromatography (IC) method for quantitative trace analysis of ammonium in 0.1 M sulfuric acid electrolyte, which is applied to EAS gas-diffusion electrode (GDE) experiments with commercial chromium nitride as electrocatalyst.

Discovery of Polythioplatinate(II) [PtS(SO)] and Study of Its Solution and Catalytic Properties.

We have discovered the first polythioplatinate(II), [PtS(SO)] (), which was synthesized in aqueous basic medium (pH 11) by hydrothermal heating at 150 °C. Polyanion comprises a discrete, triangular assembly of three Pt ions linked by two μ-sulfido ligands, and their square-planar coordination geometry is completed by two terminal S-bound sulfito ligands. Polyanion was isolated as a hydrated sodium salt, Na[Pt(μ-S)(SO)]·22HO (), which was characterized in the solid state by single-crystal X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray photoelectron spectra, and elemental analysis, in solution by Pt NMR and atomic absorption spectroscopy, and in the gas phase by electrospray ionization mass spectrometry.
