Design of a Co doped carbon Backbone with self-grown Au nanoparticles via a 'Triple Advantage' Strategy for sensitive dopamine detection.

In this study, a Co doped polyhedral carbon skeleton (Co CN) was prepared by nitrogen carbonization using ZIF-67 as a precursor. The Co CN features a rough surface with excellent electrical conductivity, and the Co atoms exhibit unique catalytic properties. Based on these characteristics, we used Co CN as a carrier to load Au nanoparticles (NPs) onto its surface through the linkage and reduction effects of polyoxometalates (POMs).

3D Printed Titanium Scaffolds with Bi-Directional Gradient QK-Functionalized Surface.

3D printed titanium scaffold has promising applications in orthopedics. However, the bioinert titanium presents challenges for promoting vascularization and tissue growth within the porous scaffold for stable osteointegration. In this study, a modular porous titanium scaffold is created using 3D printing and a gradient-surface strategy to immobilize QK peptide on the surface with a bi-directional gradient distribution.

Synergism and Mechanisms of Aging Resistance in the Use of Graphene and Carbon Nanotubes in Bitumen Composites.

Thermal oxidation has a significant effect on the durability of bitumen composites reinforced with carbon nanomaterials. However, the mechanisms of aging resistance and the effect of aging on the chemical properties, morphology, micromechanical properties, and rheology of bitumen with carbon nanomaterials are still unclear. This study investigated the mechanisms of aging resistance underlying the synergistic effects of graphene and carbon nanotubes (CNTs) on the durability of bitumen composites.

Orphan nuclear receptor NR2E3 is a new molecular vulnerability in solid tumors by activating p53.

The orphan nuclear receptor NR2E3 has emerged as a potential tumor suppressor, yet its precise mechanisms in tumorigenesis require further investigation. Here, we demonstrate that the full-length protein isoform of NR2E3 instead of its short isoform activates wild-type p53 and is capable of rescuing certain p53 mutations in various cancer cell lines. Importantly, we observe a higher frequency of NR2E3 mutations in three solid tumors compared to the reference population, highlighting its potential significance in tumorigenesis.
