Summary: The modelling of electrochemical interfaces between a liquid electrolyte and an electrode is typically done using ab initio molecular dynamics simulations from a quantum chemical perspective. Taking into account the statistical nature of the electrolyte structure through proper averages is necessary to obtain reliable results. However, running such simulations for sufficiently large systems and long enough times under potential control poses significant challenges, which will be discussed in this contribution along with potential approaches to address them.

Summary: This study designs a polyurethane-based polymer (PNPU) to construct a hybrid solid polymer electrolyte (PNPU-PVDF-HFP) with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) for high energy density solid-state lithium metal batteries. The PNPU-PVDF-HFP SPEs maintain the multiple hydrogen bonding modes of PNPU, which improves the mechanical properties and compact structure of the polymer membrane. PNPU is involved to form double Li+ transport paths in the hybrid electrolyte, accelerating the migration of lithium ions. The PNPU-PVDF-HFP SPEs exhibit suitable tensile strength, high elongation, high ambient ionic conductivity, ductility, and stability on the lithium metal anode interface, resulting in stable cycling performance of solid-state batteries.

Summary: This study reveals that NiMo electrodes used in intermittent water electrolysis easily suffer from oxidation during power interruption, leading to the loss of active sites and conductivity. By understanding the degradation mechanism, a chromium (Cr) coating is successfully applied as a protective layer to inhibit oxygen reduction reaction (ORR) and significantly enhance the stability of NiMo electrodes in intermittent electrolysis. Experimental and Molecular Dynamics (MD) simulations show that the Cr coating acts as a physical barrier for preventing oxygen diffusion while allowing other species to pass through.

Summary: This study evaluates the osteoconduction of a 3D printed PEEK scaffold treated with plasma immersion ion implantation (PIII) compared to an untreated structure using micro-CT imaging. The treated PEEK scaffold contains denser and larger amounts of bone within the interior volume, while the untreated PEEK has more bone immediately outside the scaffold boundaries. This difference is attributed to the improved hydrophilicity and protein covalent binding provided by the PIII treatment.

Summary: To achieve a zero-carbon-emission society, increasing the use of clean and renewable energy is crucial. However, renewable energy resources have limitations in terms of geographical locations and limited time intervals for energy generation. Therefore, there is a rising demand for high-performance energy storage systems (ESSs) to effectively store and utilize energy during peak and off-peak periods. Supercapacitors, particularly electrical double layer capacitors (EDLCs), show promise as short-term ESSs due to their long cycle retention, high power densities, fast charge/discharge characteristics, and moderate operating voltage window. However, further research is needed to increase the operating voltage and energy densities of EDLCs while maintaining long-term cycle stability and power densities, which are crucial for ESS operation. This article examines advancements in EDLC research to achieve a high operating voltage window and high energy densities for next-generation supercapacitor-based ESSs.

Summary: In this study, a defect-rich SrTiO3-x coating was applied on a Ni-rich layered cathode (LiNi0.8Co0.15Al0.05O2) to enhance its electrochemical performance. The optimized sample exhibited a high discharge capacity of around 170 mA h/g after 200 cycles at 1C rate, with a capacity retention of over 81.1%. Postmortem analysis revealed that the SrTiO3-x coating not only alleviated the growth of internal resistance due to uncontrollable cathode-electrolyte interface evolution but also served as a lithium diffusion channel during prolonged cycling. This work presents a feasible strategy for improving the electrochemical performance of high-nickel content layered cathodes for next-generation LIBs.

Summary: In this study, polydimethyl glutarimide (PMGI) layers were modified to introduce free radical covalent binding sites. Horseradish peroxidase (HRP) enzyme was successfully immobilized on the treated PMGI, and the treated PMGI was incorporated as a gate dielectric layer in a three-terminal electrolyte-gated device. The presence of HRP on the plasma-modified PMGI gate dielectric layer altered the device characteristics and allowed for readout detection.

Summary: This paper reports a pH-universal HER catalyst Ru/a-Ni-MoO3, which shows superior performance compared to the commercial Ru/C catalyst. The electron transfer from Ru to a-Ni-MoO3 is identified, leading to a modified electronic structure of the Ru active sites. Density functional theory calculations reveal that the modulated electronic structure facilitates the interactions between the Ru active sites and the reaction intermediates, promoting the HER reaction steps. The experimental and theoretical findings provide insights into enhancing pH-universal HER performance.

Summary: This study developed a metal-organic framework (MOF) material loaded with Ru and Ni nanoparticles for the capture and conversion of CO2 to CH4. Low nanocatalyst loadings improved overall performance and facilitated complete CO2 release and conversion. Ru-loaded Mg-CUK-1 exhibited good oxygen tolerance, while Ni-loaded Mg-CUK-1 could not maintain initial catalytic performance. Ru aided the re-reduction of NiO to Ni, leading to enhanced overall performance of the hybrid material.
