Plastic Waste Conversion by Leveraging Renewable Photo/Electro-Catalytic Technologies.

Plastics have revolutionized our lives; however, the exponential growth of their usage has led to a global crisis. More sustainable strategies are needed to address this dilemma and transform the plastics economy from a linearity to a circular model. Herein, we systematically summarize the recent progress in renewable energy-driven plastic conversion strategies, including photocatalysis, electrocatalysis, and their integration. By introducing the significant works, the design principles, mechanisms, and system regulations, we decipher and compare the various aspects of plastic conversion. These approaches show high reactivity and selectivity under environmentally benign conditions and provide alternative reaction pathways for plastic conversion. Plastic upcycling as a chemical feedstock can yield value-added chemicals and fuels, contributing to the establishment of a sustainable and circular economy. Additionally, several innovations in reaction engineering and system designs are presented. Finally, the challenges and perspectives of sustainable energy-driven plastic conversion technologies are comprehensively discussed.

Outbreak of dengue Fever in central China, 2013.

In 2013, the first dengue fever (DF) outbreak in central China was reported in the central of Henan province, northern temperate regions, although they have been sequentially recorded in Southern China. 106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3 (DEN-3) infections. 62/392 (15.8%) local health persons showed DEN antibodies positive. To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China.
