Summary: Nanostructured carbonaceous materials, such as CNTs, graphene, and activated carbon, exhibit excellent conductivity and larger surface area, which can significantly enhance the electrochemical performance of transition metals based pseudocapacitive materials. The study successfully prepared copper sulfide nanochips via the hydrothermal method and improved their electrical conductivity and capacitive properties by forming nanohybrids with conductive CNTs. The nanohybrid sample demonstrated enhanced capacitive ability, gravimetric capacitance, and cyclic-aptitude compared to the pristine cobalt sulfide sample, showing great potential for practical application in next-generation electrochemical devices.

Summary: The article explores the application of surface polymerization techniques in novel zinc oxide (ZnO)/polymer hybrids, aiming to enhance the physicochemical properties of polymer materials by precise control of the microstructure of polymer/zinc nanoparticle blends. Progress has been made in this field through the development of controlled radical polymerization methods, enabling deliberate modification of zinc oxide surfaces with polymer chains. The resulting enhancement in particle compatibility allows for the creation of multifunctional polymer/ZnO nanocomposite materials with potential applications in optics, catalysis, energy, and biomedical areas.

Summary: This study has developed two series of catalysts, xAu/UiO-66-NaBH4 and xAu/UiO-66-N2H4 nanohybrids, for nitrogen reduction reaction (NRR). The sacrificial effects of a few faradaic efficiencies (FEs) greatly enhance the NH3 yield rates (rNH3), which are influenced by the loaded Au or lost-linker defects on the electrochemically active surface areas and charge transfer efficiencies. The optimal 5Au/UiO-66-NaBH4 exhibits a high rNH3 of approximately 163.33 μg mgcat-1 h-1 but only a moderate FE of approximately 55.52% due to the sacrificial effects of FEs.

Summary: It is crucial to design catalysts with unique spatial structures and excellent electrochemical performance. Although non-noble metal catalysts are less active than Pt-based ones, their catalytic ability can be enhanced by the synergistic effect of different components. In this study, several dendritic-like CoP@NiCo-LDH hetero-catalysts were synthesized using a multi-step growth route. The CoP@NiCo LDH-100 samples exhibited superior performance in OER and HER compared to commercial IrO2 (OER) and Pt/C (HER) in alkaline electrolyte. Density functional theory (DFT) calculation showed that the composites had low adsorption energy and tunable charge redistribution at the interface. The enhanced conductivity of the catalyst was confirmed by an increased Fermi-level PDOS value. The upward shift of the D-band center facilitated the desorption of intermediates and accelerated the hydrolysis dissociation process, leading to improved HER activity and reduced overall electrolysis voltage.

Summary: In this study, Ta3N5-TaON-PEDOT-PANI nanohybrids were synthesized and evaluated for electrochemical oxidation and dye degradation applications. The nanohybrids showed excellent activity and stability towards MBZ oxidation and photocatalytic dye degradation, with a highest dye degradation efficiency of > 97% obtained. A plausible dye degradation mechanism was proposed based on UV-Vis spectra, confirming the potential catalytic oxidation and degradation behavior of the nanohybrids.

Summary: The hybrid materials between carbonaceous nanomaterials and transition metal oxides have shown high electrocatalytic efficiency. This study aimed to obtain Co2SnO4 (CSO)/RGO nanohybrids through in situ and ex situ methods and evaluate their performance in the amperometric detection of hydrogen peroxide. The results showed that both in situ and ex situ nanohybrids were suitable for detecting hydrogen peroxide, with more efficiency obtained using the reduction mode.

Summary: Nanostructured hybrids of graphene oxide and palladium were synthesized through one-step solvent-free gas phase treatment, followed by in situ decoration with palladium in the liquid medium. The proposed method offers an eco-friendly alternative for obtaining nanohybrids of graphene oxide and palladium nanoparticles under mild conditions. The hybrids demonstrated the formation of nanometer-sized crystalline palladium particles, with larger particle sizes observed for diamine-functionalized substrates compared to monoamine or non-functionalized substrates. The thermal stability of the obtained hybrids was slightly lower than pristine graphene oxide.

Summary: We demonstrate a versatile synthesis strategy to combine metal-organic frameworks with nanoparticles, allowing for the formation of mono-, bi-, tri-, and quaternary composites. This method does not require specific surface structures or functionalities on the pre-formed cores. The controlled diffusion rate of alkaline vapors regulates the growth of MOFs and encapsulation of NPs.

Summary: The study identified high tensile circumferential stresses as the main cause of radial crack formation in Cu metallized through-glass via (TGV) substrates during annealing. By applying a heating rate <= 6.5 degrees C/min, crack-free metallized TGV substrates were achieved, attributed to the significant activation of stress relaxation mechanisms in the Cu.

Summary: The study found that TCV pitch dimension is a critical parameter in limiting catastrophic failures, and the prevention of radial and circumferential crack formation is the most critical step in mitigating risk of failure. By redesigning TCV shape, controlling metallization thickness, and using lower annealing heating rate, the thermo-mechanically induced cracks were successfully mitigated.
