Hydrothermally Constructed MoS/ZnInS Heterostructure for Promotion of Photocatalytic H Evolution.

The integration of the second material with unique properties into original material to fabricate heterostructure represents an effective strategy to enhance photocatalytic H evolution. Herein, we synthesized a MoS/ZnInS heterostructured photocatalyst using a two-step hydrothermal method. The resulting MoS/ZnInS displayed the flower-like morphology formed by staked nanosheets, significantly accelerating photocatalytic H evolution performance.

Global, regional, national burden and gender disparity of cataract: findings from the global burden of disease study 2019.

Background: To evaluate the global burden of cataracts by year, age, region, gender, and socioeconomic status using disability-adjusted life years (DALYs) and prevalence from the Global Burden of Disease (GBD) study 2019.

Methods: Global, regional, or national DALY numbers, crude DALY rates, and age-standardized DALY rates caused by cataracts, by year, age, and gender, were obtained from the Global Burden of Disease Study 2019. Socio-demographic Index (SDI) as a comprehensive indicator of the national or regional development status of GBD countries in 2019 was obtained from the GBD official website.
