Through innovation, new green products have entered people's lives and play an important role in carbon reduction. New energy intelligent vehicles have reached a higher comfort level, and autonomous driving capabilities have gradually improved in China. In the first half of this year, the market s...
The doped material delivered a reversible capacity of up to 242 mAh/g at 0.05 A/g, excellent rate capabilities of 123 mAh/g at a high current of 1 A/g, and long-term cycle life with ~88% capacity retention after even 600 cycles. Electrochemical impedance spectroscopy (EIS) and ...
Unit ThreeLet's live a low-carbon life第三单元 我们来过低碳生活吧 Lesson 11 第11课 Listen and say听录音,学对话 Come on, you boys.来吧,孩子们。Are you tired?你们累了吗?No we're not.不,我们不累。It's jus...
Carbon tetrachloride is known to deplete the ozone layer, where it is responsible for 17% of the ozone-destroying chlorine now in the stratosphere due to human activities. Carbon tetrachloride has a half-life of between 30 and 100 years.Its DOT Label is Poison, and its UN number is 1846....
Assuming half of the scientists from China flew in from Shanghai, this would increase China's emission by 10%. Taking into account that China contributes 20% to the overall emissions of EGU travel, this uncertainty is less than 2% in total....
The amount of physical activity measured in the survey encompassed three life domains: work, leisure and transport. Only the sum of work and leisure activities were taken as the background physical activity. To estimate the impacts for people with low, medium and high background physical activity...
It was shown that additional demand-side policies and assumptions about lifestyle changes10 or low energy demand11 reduce the need for bioenergy with carbon capture and storage (BECCS) and benefit sustainability, but the economic drivers for CDR were not directly attacked and carbon removals were ...
life cycle analyses of wood products or wood-based bioenergy commonly treat uses of wood as ‘carbon neutral’ provided that the forests harvested are managed ‘sustainably’3,5. Carbon neutral means that they do not count the carbon that was present in vegetation (biogenic carbon) and emitted ...
