Summary: Hollow-structured NiO + Ni nanofibers wrapped by graphene were successfully prepared via a simple method. The electrode demonstrated optimal electrochemical performance, cycling stability, and rate capability, attributed to the increased active sites and decreased charge transport distance. Excessive introduction of graphene resulted in sharp loss of electrochemical performance due to agglomeration on nanofiber surfaces.

Summary: This paper investigated the high nickel cathode LiNi1-x-yMnxAlyO2 (NMA) and found that its high rate performance is less satisfactory compared to conventional cobalt cathode. By using NaAlO2 as the aluminum source, cobalt-free materials NMA80, NMA90, and NMA95 were synthesized with high crystallinity and purity. Among them, NMA90 showed excellent specific capacity at high discharge rate, indicating potential for fast charging technology development.

Summary: Copolymerization of an electron-rich donor (D) unit with an electron-deficient acceptor (A) unit to construct efficient D-n-A-n type donors is an effective strategy for organic solar cell applications. In this work, a series of fused A units with different electron-deficient ability were constructed using benzo[2,1-b:3,4-b']dithiophene and benzopyrazine (BP), benzothiadiazole (BT), and benzoselenadiazole (BS). Three polymer donors were synthesized and their structure-performance relationships were systematically investigated. Among the three polymers, PBDP-BT showed the highest hole mobility. The device based on PBDP-BT:Y6 achieved an outstanding power conversion efficiency (PCE) of 15.14%, surpassing those based on PBDP-BP:Y6 and PBDP-BS:Y6.

Summary: Mediated Fenton reaction can enhance intracellular oxidative stress through producing toxic ·OH. However, the delivery of Fe2+ in high doses to tumors and its cytotoxicity to normal tissues pose a challenge. Thus, a controllable Fe2+ delivery system has been developed to activate the Fenton reaction and enhance Fe2+ accumulation in tumors.
