■ Published by: University of Portsmouth

■ Keywords: waste, recycling, batteries

■ Abstract:

Consumers told that not recycling their batteries 'risked polluting the equivalent of 140 Olympic swimming pools every year' were more likely to participate in an electronic waste recycling scheme, a new study has found.

Headline: Carbon dioxide removal should receive additional financial support, experts urge

■ Release Date: 2022.12.20

■ Published by: Potsdam Institute for Climate Impact Research (PIK)

■ Keywords: carbon dioxide, greenhouse gases, carbon removal

■ Abstract:

Cleaning up greenhouse gases after they have been emitted should be incentivized by subsidies. New evidence from an economic analysis considering international markets suggests an important reason why subsidies should be higher than the price put on carbon emissions to incentivize their reduction. Researchers analyze policies for removing carbon dioxide from the atmosphere and storing it underground or in products. The suggested different pricing is not due to technological challenges, but linked to an economic effect called leakage.

Headline: Materials science: A rough start can lead to a strong bond

■ Release Date: 2022.12.21

■ Published by: Institute of Industrial Science, The University of Tokyo

■ Keywords: polymers, steel, automotive

■ Abstract:

Researchers developed a cheap and simple process to create nanoscale structures on the surface of galvanized steel, which is commonly used in the automotive industry, that provided a more conducive interface for attaching injection-molded polymers. This method may lead to lower-cost industrial production of lightweight and durable polymer-metal composite materials.

Headline: Scientists discover a novel photophysical mechanism that has achieved record-breaking efficiency for organic photovoltaics

■ Release Date: 2022.12.21

■ Published by: City University of Hong Kong

■ Keywords: organic photovoltaics, solar, cells

■ Abstract:

Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.
