Objective To analyze the incidence trend of cancer from 2015 to 2020 in Sichuan Province and provide a reference for prevention and control of cancer. Methods Based on the cancer-related case information data on the Homepage of medical records in Sichuan Province from 2015 to 2020, the crude incidence rate was calculated, and the average annual change percentage (AAPC) of incidence rates was analyzed with Joinpoint 4.2.0.1. Results The new cancer cases in Sichuan Province increased from 181 490 in 2015 to 276 770 in 2020, and the incidence rate increased from 198. 57/105 in 2015 to 304.76/105 in 2020. From 2015 to 2020, the average annual percentage change (AAPC) was 7.514%, 6.751%, 8.611%, 4.713%, and 6.838%, respectively. The incidence of cancer in the Chengdu Plain Economic Zone and the Northwest Sichuan Ecological Economic Zone showed a rising trend, AAPC values with statistical significancebeing 7.549% and 9. 668%, respectively. From 2015 to 2020, the incidence rate of lung cancer, colorectal cancer, breast cancer, cervical cancer and prostate cancer in Sichuan Province showeda rising trend, with AAPC values of 11.220% (95% CI; 5.866-16.845), 6.606% (95% CI: l.395-13.202), 6.322% (95% CI: 1.411-11.472), 5.765% (95% CI: l.431-10.284) and 13. 222% (95% CI : 7.396-19.364), respectively. Conclusion The incidence of cancer in Sichuan Province shows a rising trend, and the prevention and control situation is grim. Lung cancer, digestive system cancer, breast cancer, cervical cancer and prostate cancer are the dominant cancer types in Sichuan Province, and specific prevention, control and screening should be strengthened.

Aqueous zinc‐sulfur (Zn‐S) batteries show great potential for unlocking high energy and safety aqueous batteries. Yet, the sluggish kinetic and poor redox reversibility of the sulfur conversion reaction in aqueous solution challenge the development of Zn‐S batteries. Here, we fabricate a high‐performance Zn‐S battery using highly water‐soluble ZnI2 as an effective catalyst. In situ experimental characterizations and theoretical calculations reveal that the strong interaction between I− and the ZnS nanoparticles (discharge product) leads to the atomic rearrangement of ZnS, weakening the Zn‐S bonding, and thus facilitating the electrochemical oxidation reaction of ZnS to S. The aqueous Zn‐S battery exhibited a high energy density of 742 Wh kg(sulfur)−1 at the power density of 210.8 W kg(sulfur)−1 and good cycling stability over 550 cycles. Our findings provide new insights about the iodide catalytic effect for cathode conversion reaction in Zn‐S batteries, which is conducive to promoting the future development of high‐performance aqueous batteries.

Zn metal anodes in aqueous batteries experience inhomogeneous deposition and corrosion issues. Herein, we introduced, at a low concentration, dioxane (DX) as an electrolyte additive to stabilize a Zn anode. The oxygen sites of DX endowed it with a strong affinity for Zn and Zn2+, resulting in its adsorption onto the Zn electrode surface and its coordination with Zn2+ locally. The Zn2+-DX species exhibited a decreased lowest unoccupied molecular orbital energy level relative to those of water-involved components. The DX additive not only inhibited side reactions but also generated a stable solid–electrolyte interphase on the Zn electrode, ensuring a uniform Zn deposition. As a result of including the additive, the cycle life of the Zn symmetric cell was extended from 99 h to 2100 h, and the coulombic efficiency in Zn//Cu cell reached 99.5%. [ABSTRACT FROM AUTHOR]

Aqueous batteries with high safety and cost efficiency usually employ metallic cations as charge carriers. Recently, ammonium (NH4+) ion batteries using the nonmetal NH4+ as a charge carrier exhibit distinct electrochemical features from conventional aqueous batteries. Herein, the electrochemical performances of a bimetallic hydroxide material are systematically studied with different charge carriers in the electrolytes, including NH4+, as well as the conventional monovalent metallic cations K+ and Na+, respectively. Electrochemical results indicate that the charge storage process using NH4+ as the working ions exhibits a higher discharge plateau, smaller electrochemical polarization, and larger discharge capacity than that using conventional metallic charge carriers. Experimental characterizations and theoretical calculations suggest that the strong interaction between NH4+ and the electrode material, as well as the low NH4+‐ion diffusion barrier lead to these superior electrochemical features. The assembled NH4+‐ion battery exhibits a good energy density of 123 Wh kg(cathode+anode)−1 at the power density of 480 W kg(cathode+anode)−1. These fundamental findings are important for developing good safety, low‐cost, and high‐energy aqueous batteries with sustainable NH4+ charge carriers. [ABSTRACT FROM AUTHOR]
