Summary: This work investigates the drug-release control by degradation from biodegradable metallic surfaces. Curcumin-coated zinc had a higher degradation rate and a higher curcumin release compared to curcumin-coated iron, due to its different degradation structure. The unique degradation behaviors of degradable metallic surfaces can directly influence drug release without the need for external electrical stimulus.

Summary: Drug-eluting stents (DESs) are commonly used for the treatment of coronary artery disease. The evolution of the drug-eluting layer on the stent's surface is crucial for its functionality. Using biodegradable polymers is an attractive approach as it reduces the risk of late thrombosis after stent implantation. Understanding drug-release behavior from these polymers is important for improving the safety and efficacy of stent treatments.

Summary: On-demand drug delivery systems combined with wireless implants can control drug release, reducing dosage and side effects. Researchers designed a release system based on a modified electroresponsive polypyrrole nanoparticulate film for negatively charged compounds. They also developed an ultrasonically powered mm-sized implant to electronically control the on-demand drug delivery system in vivo. The feasibility of wireless, controllable drug release was demonstrated through in vitro and in vivo characterization using fluorescein as a model drug.

Summary: The aim of this study is to investigate the electrochemical deposition of polypyrrole films using choline chloride-based ionic liquids and simultaneously embed and release indomethacin. The morphology of the films was observed using scanning electron microscopy and the presence of polymer and drug was confirmed using FT-IR analysis. The hydrophilic character of the samples was evaluated and their electrochemical characterization was performed in artificial saliva. Indomethacin release was determined using UV-VIS spectra and a kinetic law for release was established based on Fick's law of diffusion.

Summary: Intermediate temperature solid oxide fuel cells oxygen electrodes are modified by introducing nanocrystalline interlayers made of different materials, which significantly reduces the area specific resistance of the electrodes and enhances the active surface area for oxygen reduction reaction as well as the contact between the electrode and the electrolyte. The developed LSC/LSCF electrode in an anode-supported single cell shows high power output and stable cell voltage at 600 degrees Celsius.

Summary: In this study, a series of MnCo2-xFexO(4) powders were synthesized by the sol-gel method to investigate the effect of partial Fe substitution on the physicochemical and electrochemical properties of MnCo2O4 spinel. The synthesized powders were characterized using various techniques. The findings revealed that the electrocatalytic activity towards oxygen evolution reaction (OER) was enhanced when Fe was partially substituted for Co, with the highest activity observed at x = 0.5. This indicates that tuning the eg occupancy at the octahedral sites through Fe substitution can modulate the catalytic activity of OER.

Summary: In this study, the mechanical modification of MnCo2O4 (MCO) spinel powders was performed through a low-energy ball milling process for the first time. The research found that the mechanical and chemical modification of the MCO spinel could enhance its electrocatalytic properties. After 30 days of ball-milling, the overpotential of MCO spinel decreased to 352 mV at 10 mA cm-2 when the amount of Nafion was reduced to 10% of its initial value, indicating that the composition of catalyst ink and layer was an important factor influencing the efficiency of the catalyst in the OER.

Summary: The specific role of adding graphene oxide (GO) to nickel-iron (NiFe) and cobalt-nickel-iron (CoNiFe) mixed oxides/hydroxides in the oxygen evolution reaction (OER) was investigated. The morphology, structure, and OER catalytic activity of the catalysts with and without GO were studied. Significant improvements in OER activity were observed when GO was combined with NiFe or CoNiFe, attributed to the structure of NiFe and the electroactive surface area of GO.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
