Unlabelled: A scalable, hysteresis-free and planar architecture perovskite solar cell is presented, employing a flame spray synthesized low-temperature processed NiO (LT-NiO) as hole-transporting layer yielding efficiencies close to 18%. Importantly, it is found that LT-NiO boosts the limits of open-circuit voltages toward an impressive non-radiative voltage loss of 0.226 V only, whereas
Pedot: PSS suffers from significant large non-radiative recombination losses.

Transition metal chalcogenides (TMCs) have garnered significant attention as high-capacity anode materials, yet the unconventional role of the Cu collector meditating atomic-level substitution of metal-site cations by Cu ions during electrochemical cycling remains mechanistically unclear. To address this, herein, Cu-doped MoSe@C ultrathin nanosheets were synthesized via the solvothermal process and carbonization strategies. A systematic investigation was conducted to elucidate the underlying driving forces for Cu substitution at Mo sites and the crucial regulatory effects of solid electrolyte interphase (SEI) formation.

Metal-organic frameworks (MOFs) are transformative platforms for heterogeneous catalysis, but distinguishing atomically dispersed metal sites from subnanometric clusters remains a major challenge. This often demands the integration of multiple characterization techniques, many of which either lack the resolving power to distinguish active sites from their surrounding environments (e.g.

Organic electrochemical transistors (OECTs) continue to be the subject of much detailed and systematic study, being suitable for a diverse range of applications including bioelectronics, sensors, and neuromorphic computing. OECTs conventionally use a liquid electrolyte, and this architecture is well suited for sensing or bio-interfacing applications where biofluids or liquid samples can be used directly as the electrolyte. A more recent trend is solid-state OECTs, where a solid or semi-solid electrolyte such as an ion gel, hydrogel or polyelectrolyte replaces the liquid component for an all-solid-state device.

Wearable sweat sensors offer noninvasive health monitoring through multiplexed biomarker analysis, delivering real-time diagnostics with continuous operational capability. However, chronic cutaneous interface hydration during prolonged monitoring induces adhesive delamination phenomena that manifest as signal attenuation, which fundamentally limits their clinical reliability. To address this challenge, we developed a thermodynamically adaptive polymer interface combining three functional components: mussel-inspired catechol moieties for moisture-tolerant adhesion, hydrophobic acrylates ensuring mechanical stability, and N-isopropylacrylamide enabling thermal responsiveness.

Regeneration of infected bone defects (IBDs) requires biomaterials capable of dynamically coordinating antimicrobial, anti-inflammatory, and osteogenic functions. Overcoming the spatiotemporal mismatches in treating IBDs remains a critical challenge. Here, we designed a temporally controlled therapy based on gelatin methacrylate (GelMA)-based nanocomposite hydrogels (GCS) coembedded with sulfur quantum dots (SQDs) nanoenzymes and calcium-phosphorus oligomers (CPOs.
