Herein, an innovative oral treatment strategy for IBD is proposed, which utilizes calcium alginate hydrogel as a carrier to deliver Co₃O₄ nanocages loaded with total glucosides of paeony (TGP) into the body. This design ingeniously exploits the protective properties of the alginate outer layer to ensure that the enzyme is not prematurely degraded when passing through acidic gastric juice. However, upon reaching the inflamed intestinal site, the overexpressed H₂O₂ there mixes with a specific solution, causing the hydrogel to degrade and release Co₃O₄@TGP. These negatively charged nanozymes can precisely recognize and accumulate in the inflamed colonic tissue, achieving targeted therapy through their unique charge characteristics. More importantly, Co₃O₄ itself possesses excellent catalytic activity, effectively consuming excess H₂O₂ at the site of inflammation and degrading into 10 nm small particles in the process, while simultaneously releasing TGP. Together, they exert dual effects of scavenging reactive oxygen species (ROS) and anti-inflammation. Its therapeutic mechanism involves fine regulation of the expression of key proteins such as TLR7, MYD88, and GAPDH, as well as effective inhibition of the NF-κB signaling pathway. This series of actions not only reduces the release of various pro-inflammatory cytokines (such as TNF-α, IL-18, IL-1β, IL-6, and HMGB1) but also promotes the production of the anti-inflammatory cytokine IL-10, thereby effectively maintaining the integrity of the intestinal barrier.

Synthesis of a single-phase material is commonly achieved by controlling experimental conditions. Synthesizing materials that incorporate multiple specific spatially distributed chemical phases is often challenging, especially if different phases must be organized into well-defined spatial patterns. Here, we present an efficient solid reaction laser annealing (SRLA) approach to directly write regions of different local chemical compositions. We demonstrate the practical utility of our approach by locally writing microscale patterns of distinct chemical phases in vanadium oxide thin films. Specifically, we achieved the controlled local recrystallization of a uniform V₂O₃ matrix into VO₂, V₃O₅, and V₄O₇ regions exhibiting sharp 1st- and 2nd-order metal–insulator phase transitions over a wide range of critical temperatures, i.e., a characteristic feature of select vanadium oxides that is extremely sensitive to even minute structural or compositional imperfections. We utilized the local chemical phase writing to pattern spiking oscillators with distinct electrical behavior directly in the thin film sample without employing elaborate lithography fabrication.

Novel C, N co-doped ZnO/Co₃O₄/CoFe₂O₄/Fe₃O₄ quaternary oxide was engineered using a tri-metallic zeolitic imidazolate framework (Zn/Co/Fe-ZIF). The synthesized material degraded 85% tetracycline (TC) within just 15 s of visible light illumination (and achieved a total degradation of 90.9% in 6 min). The catalyst's remarkable performance was ascribed to the synergistic effect of dual S-scheme heterojunctions at the oxide's interface and the light-independent activation of H₂O₂ by the multivalent cationic sites (Co³⁺/Co²⁺ and Fe³⁺/Fe²⁺) on the catalyst. These two mechanisms not only reduced the TC degradation time to just a few seconds, but also unlocked the degradation potential of the catalyst in the absence of light (70% TC degradation was achieved under ambient dark conditions). XPS studies showed that the ZIF-mediated synthesis introduced double or triple oxygen vacancy sites and N substitutional defects, which enhanced the catalyst’s efficiency by increasing the production of reactive oxygen species on its surface. VB-XPS and UPS analysis were performed to correctly elucidate the charge transfer mechanism in the heterostructure. The results of EPR and LC–MS studies established that the synthesized heterostructure is capable of generating abundant reactive oxygen species which are responsible for the fragmentation of TC molecules within a short period of time.

Al7075-BNNT composite is fabricated using a multi-step process involving ultrasonication, cryomilling, and spark plasma sintering (SPS).
