Summary: In this study, four types of biochar were prepared using urea and rice husk as precursors and tested for their catalytic degradation ability of dimethomorph. The results showed that increasing the nitrogen doping level greatly enhanced the catalytic removal efficiency of dimethomorph in the presence of peroxymonosulfate. The ability of N-doped biochar to activate peroxymonosulfate was found to be mainly related to the content of pyrrole N, graphite N, carbonyl, and the degree of defects.

Summary: By studying (La, Nd, Pr)NiO2 system using an impurity model, the nature of the parent compound and hole-doped states have been explored by considering crystal field splitting, Ni-3d multiplet structure, and orbital hybridization. For the parent compound, Ni-3dz92 states are found to spread over a large energy range in the spectra and cannot be represented by a single orbital energy. Adding additional ingredients in the hole-doped systems can still result in the lowest-energy hole-doped state having a singlet character.

Summary: This study investigates the possible formation of spin and charge stripe states in hole-doped nickelates using advanced computational methods. It reveals the instability of the C-type spin state and the distortions associated with the formation of stripe phases. This work is important for understanding the anomalous properties of hole-doped nickelates.

Summary: Superconductivity in doped NdNiO2 arises from the competition of local symmetries and the impact of realistic values of charge-transfer energy, leading to a different scenario compared to high-T-c cuprates. The results show that correlation effects beyond purely on-site interactions should be considered in obtaining effective two-band models.

Summary: Nitrogen-doped graphene oxide dots (NGODs) can serve as an efficient photosensitizer for Photodynamic therapy (PDT) by producing H2O2 under white-light irradiation in the presence of ascorbic acid (AA). The unique structure of NGODs restricts the transfer of photogenerated electrons for H2O2 production, showing high potential for effective and accurate deployment in PDT.

Summary: Researchers predict that the critical temperature Tc of unconventional p-wave superconductors can be significantly enhanced by coupling them with conventional s-wave or d-wave superconductors through an atomically thin ferromagnetic layer. They demonstrate that this boost in Tc is tunable by the magnetization direction in the ferromagnetic layer, and can also be achieved using the Zeeman effect of an external magnetic field. Their findings offer a controllable way to increase Tc in p-wave superconductors and make the exotic physics associated with such materials more easily accessible experimentally.

Summary: Under the influence of the BCS-electron-phonon theory, experimentalists have discovered high temperature conventional superconductors in pressurized hydrides, while theorists have been predicting and explaining these findings. However, the alternative theory of hole superconductivity suggests that no superconductivity exists in these materials.

Summary: Understanding the rich and competing electronic orders in cuprate superconductors may provide important insight into the mechanism of high-temperature superconductivity. Here, the authors report a distinct charge order with Little-Parks like resistance oscillations at magnetic fields up to 10 T and around Tc in lightly doped Bi2Sr2CaCu2O8+x.

Summary: In this study, boron and nitrogen co-doped porous composites were successfully synthesized using rice husks as both carbon and silicon sources, and NH4HB4O7 as the porogen reagent and heteroatom source. The resulting composites exhibited unique porous architecture, large specific surface area, and improved electronic conductivity, making them promising candidates for lithium-ion battery anodes with high reversible capacity, exceptional rate performance, and superior cycling stability.

Summary: B-doped porous C/SiOx composites were prepared from rice husks and H3BO3 and showed improved electrochemical performance. The B-doped C skeleton relieved volume change of SiOx and enhanced electronic conductivity. The composites had a unique porous structure, large specific surface area, and exhibited good cycling capacity and stability. B-doping also decreased Li+ migration barrier in C matrix. The optimized electrode showed high cycling capacity and long cycle life as a Li-ion battery anode.

Summary: Despite efforts to find room temperature ferromagnetic 2D materials, only a few have been synthesized. A recent study confirmed room temperature ferromagnetism in a multilayer structure. However, calculations showed an antiferromagnetic ground state in the monolayer and bilayer systems. Further investigation revealed that hydrogen-induced ferromagnetism was possible. The resulting systems showed a ferromagnetic ground state and optically transparent behavior.

Summary: Ti(3)C(2)Tx (T = -O) MXene quantum dots (MQDs) and N-doped carbon dots (NCDs) were interspersed on CdS nanoparticles to enhance the photocatalytic hydrogen production. The hydrogen production rate of the composite material reached 5.64 mmol g(-1) h(-1), which was significantly higher than that of bare CdS and Pt/CdS. The research also improved the cycling stability of CdS-based photocatalysts.
