Summary: An experimental analysis was conducted to optimize the structure of Ni-Ni(OH)(2)/NiO core-shell nanowire electrodes for pseudocapacitor applications. The thickness and composition of the active phase shell were found to be affected by thermal treatments at different temperatures, resulting in varying capacitance values. Tailoring the capacitance of the electrodes by controlling the nanowire length was evaluated, showing that mass transfer resistance can be negligible within a certain range.

Summary: "By using Ni as template for electrodeposition and subsequent galvanic replacement of Pd, a self-supporting and shell-core Pd-Ni@Ni nanowire arrays (NAs) catalytic electrode was prepared to address the high onset potential and gaseous product generation in carbohydrazide (CHZ) electrooxidation on pure Ni catalyst. The introduction of Pd with minute mass loadings of 2.7-5.3 μg cm(-2)achieved a negative shift of onset potential of CHZ electrooxidation by 320 mV regardless of Ni supports. Pd in Ni@Pd-Ni NAs electrode facilitated the chemical dissociation of CHZ into N2H4 and/or H-2, leading to side reactions such as N2H4 and/or H-2 electrooxidation. A direct CHZ fuel cell with Ni@Pd-Ni NAs anode exhibited an open circuit voltage of 1.05 V and a peak power density of 22.90 mV cm(-2)at 303 K operating temperature."

Summary: The inferior performance of non-precious metals in electrocatalytic hydrogen evolution is mainly due to the improper adsorption strength of intermediates. A core-shell heterostructure of CoP@Ni with metallic Ni supported by CoP nanowire array is developed, and it exhibits superior activity in hydrogen evolution. The electronic structure of CoP@Ni is tuned to modulate the adsorption strength of intermediates, leading to enhanced charge transfer and lower energy barrier in the reaction pathway.

Summary: Polypyrrole (Ppy) and Ppy/Ni(OH)(2)-NiO nanocomposite were prepared through in situ polymerization oxidation reaction on glass, with the composite formed by the oxidation of NiSO4. The average particle sizes of Ppy and Ppy/Ni(OH)(2)-NiO were 160 and 250 nm, respectively, and the bandgap values were 1.70 and 1.44 eV, respectively. The crystalline nature of Ppy increased after composite formation, with characteristic peaks observed. A hexagonal Ni(OH)(2) was confirmed inside the composite. The glass/Ppy and glass/Ppy/Ni(OH)(2)-NiO were utilized as optoelectronic devices, with J(ph) values of 0.12 and 0.85 mA·cm(-2), respectively. The composite optoelectronic exhibited a photoresponsivity (R) of 12.5 mA·W-1 and a detectivity (D) of 2.79*1011 Jones.

Summary: The toxic impact of microplastics/nanoplastics in plants and the food chain is a major concern. While there has been significant research on their effects in aquatic ecosystems, their impact in terrestrial ecosystems is not well understood. Studies have shown that microplastics/nanoplastics can alter plant morphology, physiology, biochemistry, and genetics to varying degrees. However, there is a research gap in understanding how microplastics/nanoplastics enter plants, factors influencing their phytotoxicity levels, and potential strategies for remediation in terms of food safety and security. This review provides an overview of the routes of accumulation and transmission of microplastics/nanoplastics in plant tissues, factors influencing plant stress, and potential solutions to improve food quality and quantity.
