The use of an identical electrolyte in electrochemical metallization (ECM)-based neuron and synaptic devices has not yet been achieved. We demonstrate ECM devices containing the same ferroelectric PbZr_0.52Ti_0.48O₃ (PZT) electrolyte, which can sustain both neuron and synaptic behavior depending on the active electrode. The Ag/PZT/La_0.8Sr_0.2MnO₃ (LSMO) threshold switching memristor exhibits abrupt and volatile resistive switching characteristics, resulting in neuron devices. In contrast, the Ni/PZT/LSMO memory switching memristor displays gradual, non-volatile resistive switching behavior which leads to synaptic devices. The divergent behavior of the ECM devices is attributed to greater control of cation migration through the ultrathin ferroelectric PZT.

This review highlights single-aggregate spectroscopy studies of conjugated polymer aggregates based on a combination of solvent vapor annealing and single-molecule fluorescence techniques and draws mesoscopic connections between morphology, electronic coupling, and photophysics in conjugated polymers.

Topological semimetal HoPtBi exhibits anomalous AMR effect in paramagnetic state. The AMR exhibits a novel transition from a quasi-twofold to fourfold symmetry and finally forms a stable rotated fourfold symmetry as B increases. C₂ and C₄ signals with phase angle transitions dominate the novel AMR. Anisotropy of magnetic-field tunable effect induces the topological band change and leads to the phase angle transition.

Infrared-active InAs quantum dots (QDs) were synthesized with zinc coordination complexes for surface passivation, resulting in improved optoelectronic properties. The resulting InAs QDs doped with Zn showed narrowed size distributions, reduced surface defects, and modulation of electronic properties through Zn surface doping. These InAs:Zn QDs exhibited improved electrical properties when integrated into infrared photodiodes.

Silica-polymer hybrids are promising materials for bone repair. Here, biodegradable, tough and porous silica-polyurethane hybrid scaffold was successfully fabricated. Polyurethane is a versatile polymer that can be designed to have desired properties. Polymerization and alkoxysilane functionalization under high-temperature formed polyurethanes with high molecular weight, which enabled rapid gelation during the sol-gel process. This allowed porous hybrid scaffold fabrication through the facile salt-leaching method. The hybrid scaffold had self-healing properties which can self-fit into irregular bone defects. Furthermore, silicate ion release from the hybrid scaffold induced angiogenesis and osteogenic differentiation, while the porous structure suppressed chronic inflammation.

We developed a novel surface engineering technique using electrospinning and hydrothermal processes to create a flexible, binder-free electrode composed of Ti₃C₂T_x MXene/carbon nanofibers (MCNFs) coated with amorphous RuOx. The MXene served as a template for the growth of amorphous and disordered state RuO_x that positively impacted electrochemical performance. The combination of RuOx and MXene resulted in an enhanced pseudocapacitive reaction, resulting in a supercapacitor with a record-high energy density of 8.5 Wh kg^–1 at 85.8 W kg^–1, as well as excellent flexibility.

Inverted perovskite solar cells (PSCs) with a p-i-n architecture are being actively researched due to their concurrent good stability and decent efficiency. In particular, the power conversion efficiency (PCE) of inverted PSCs has seen clear improvement in recent years and is now almost approaching that of n-i-p PSCs. Here, we systematically review recent progress in the development of high-efficiency inverted PSCs, and highlight the development of charge transport materials and the effects of defect passivation strategies on the performance of inverted PSCs, with the aim of providing constructive suggestions for the future development of inverted PSCs.

We developed a ROS-responsive and controllable nanocarrier (GC-EB) that efficiently delivered a clinically used antifungal drug, voriconazole (VOR). GC-EB-VOR exhibited high penetration through corneal barriers, good retention in the cornea and controllable drug release under low concentrations of ROS. Mechanistically, the successful delivery and accumulation of GC-EB-VOR in the cornea followed by the inhibition of oxidative stress and of the inflammatory response contributed to the therapeutic effect of GC-EB-VOR against fungal keratitis.

This study provided a universality method for synthesis of nanotherapeutics for encapsulating various metal complexes. The dual-targeted MP3/AA@NPs greatly improved discrimination between cancer cells and normal cells, moreover, MP3/AA@NPs displayed good in vitro and in vivo antitumor activities as well as stimulating immunotherapeutic response.
