Amorphization was synergistically controlled by the solid-state amorphization and oxidation processes. The amorphous tribo-layer accommodated the sliding-induced elastic–plastic deformation and virtually eliminated wear.

The formation of an amorphous tribo-oxide layer and oxidative cleaving effect reduced the fracture toughness of cBN particles and increased the tendency of crack nucleation and growth. Multiple deformation pathways synergistically increased the microplastic deformability of cBN particles and reduced the wear rate.

Despite the fact that most single-side modulation is achieved through either electron or hole transfer, concerns persist regarding the limited charge transfer efficiency and material stability. Beyond this conventional thinking, a S-scheme heterojunction MoS₂/CdS@CdMOF (CMM) core–shell structure has been successfully prepared, facilitating efficient carrier escape from the perishable CdS. As a result, we observed significant enhancements in both H₂O₂ production (43.31 mmol g⁻¹ h⁻¹) and benzaldehyde formation rate (44.23 mmol g⁻¹ h⁻¹) as well as stability, which is 10 times that of CdS. Relevant research findings have demonstrated that the compact heterojunction experiences interface lattice expansion and surface compression. Thus, the Cd–O bond within the interface functions as an electron bridge, substantially improving the efficiency of charge separation. Moreover, the compressed surface configuration of MoS₂ mitigates tension to facilitate polarization of oxygen molecules and exchange of carriers, thereby decreasing the activation energy of the reaction and promoting molecular activation.

Therefore, novel GFGH nanoparticles (NPs) were successfully constructed based on metal coordination self-assembly including Gambogic acid (GA), Fe³⁺, glucose oxidase (GOX) and hyaluronic acid (HA). Due to its shuttle-like shape and HA loading, GFGH NPs enhanced tumor penetration with shuttle-like shape and enhancing cellular uptake by CD44.

GA further depleted residual intracellular GSH and downregulated GPX4, achieving a multi-pathway to break intracellular redox balance for boosting specific ferroptosis therapy. In vivo and in vitro results indicated that GFGH NPs exhibited outstanding antitumor efficacy on both normal tumor models and large tumor models.

In meso-scale simulations, using a Fiber-PPS (polyphenylene sulfide) Representative Volume Element (RVE) model, CFRTP’s thermal properties were obtained, ranging from 25 ℃ to 3000 ℃. These results were then applied to calculate the macro-scale temperature distribution of TC4/CFRTP joints. The simulated joint features closely matched experimental observations, with an error of less than 5% in cross-section and interface morphology. Compared to the common simulation method, this method can effectively capture the influence of CFRTP anisotropy on temperature distribution, enabling precise strength analysis. In the experiments, two TC4/CFRTP joints were designed: Joint A, with carbon fibers at the interface perpendicular to the laser joining direction, and Joint B, with fibers parallel to it. The joint strength of Joint A was found to be 1.706 times that of Joint B.

Herein, we report the development of a highly active bifunctional oxygen catalyst, denoted as TON@NC (trimetallic oxide needles on nitrogen-doped carbon), which consists of Ni-Co-Fe oxide nanoneedles uniformly anchored on a nitrogen-doped carbon network.
