Summary: Rice-shaped protein-copper oxide hybrid (RSPCO) nanoczymes were prepared by a one-pot method with the help of amphiphilic proteins. The enzyme-mimicking activity of RSPCO depended on the substrate structure. RSPCO showed excellent peroxidase-like activity with 3,3',5,5'-tetramethylbenzidine (TMB) as the substrate. Furthermore, the activity switching effect induced by pyrogallol (PA) was dependent on the type of enzyme-like activity and the substrate structure. Based on these findings, a highly sensitive PA colorimetric sensor was developed using RSPCO. The protein-copper oxide hybrid nanoczymes have the potential for applications in medical, environmental, and food areas.

Summary: This paper systematically investigates the ammonia (NH3)-sensing performance of phosphorus-doped graphene sensors. Stable phosphorus doping of graphene was achieved by using phosphorus pentoxide as the phosphorus source through chemical vapor deposition (CVD) at 480 oC. The results showed that phosphorus-doped graphene increased the NH3 response by 2.4 times on average, shortened the response (recovery) time by 70.6% (73.4%) on average, and had a theoretical limit of detection (LOD) of 68.76 ppb. The phosphorus-doped graphene sensor also exhibited excellent repeatability, stability, and ultra-high selectivity to NH3.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
