Incentives, penalties, and digital transformation of enterprises: evidence from China
This study uses the difference-in-difference (DID) method to explore the relative effectiveness and mechanism of the "Ten Measures on Air Pollution Prevention and Control" (TMAPPC) policy and the "carbon trading" pilot (CTP) policy on the digital transformation of enterprises. The research results show that the incentive effect of market-incentive environmental regulation on the digital transformation of enterprises is better than that of command-control environmental regulation. In addition, there are differences in the mechanism of action; the level of digital economy development and market competition can strengthen the...

Efficient Recycling of Gold and Copper from Electronic Waste by Selective Precipitation
Angew Chem Int Ed Engl. 2023 Aug 18:e202308356. doi: 10.1002/anie.202308356. Online ahead of print.ABSTRACTThe recycling of metals from electronic waste (e-waste) using efficient, selective, and sustainable processes is integral to circular economy and net-zero aspirations. Herein, we report a new method for the selective precipitation of metals such as gold and copper that offsets the use of organic solvents that are traditionally employed in solvent extraction processes. We show that gold can be selectively precipitated from a mixture of metals in hydrochloric acid solution using triphenylphosphine oxide (TPPO), as the c...

Enzyme selection, optimization, and production toward biodegradation of post-consumer poly(ethylene terephthalate) at scale
This study summarizes our research efforts toward large-scale, efficient, and economical biodegradation of post-consumer waste PET, including PET hydrolase selection and optimization, high-yield enzyme production, and high-capacity enzymatic degradation of post-consumer waste PET. First, genes encoding PETase and MHETase from Ideonella sakaiensis and the ICCG variant of leaf-branch compost cutinase (LCCICCG ) were codon-optimized and expressed in Escherichia coli BL21(DE3) for high-yield production. To further lower the enzyme production cost, a pelB leader sequence was fused to LCCICCG so that the enzyme can be secreted i...

THCB 20th Birthday classics: A Brief History of Price Controls by Annoyed Republican Administrations
By UWE REINHARDT
One of the greatest pleasures of running THCB has been to get to know and host the writings of some of my health policy heroes. This week I have already published work from Jeff Goldsmith, and Ian Morrison & Michael Millenson among others will be featured next week (as the party won’t quite stop). Perhaps one of the most amazing things was that the doyen of health economists, Uwe Reinhardt, offered to write some original pieces for THCB…prodded by former editor John Irvine. This is one of my favorites, riffing on a talk I heard him give in (I think) 1993 about how HCFA was like the Kreml...

South Africa to ban fishing around African penguin colonies for 10 years
South Africa will impose a decadelong ban on commercial fishing around six areas home to the endangered African penguin starting next year. The measure, announced by the government on 4 August, comes after an expert panel concluded that a full ban on fishing was vital for the recovery of Africa’s only penguin species.
Scientists and environmental groups have praised the move. “This is an extremely important decision, made in an emerging economy context, where so often short-term socioeconomic imperatives override longer term environmental concerns,” says Guy Midgley, interim director of the School for Climate St...

Food choice drivers at varying income levels in an emerging economy
This study yielded a mixture of individual and environment based motives which add to our understanding of the "why" aspects underlying food choice in an urban and emerging economy. The fact that these aspects are compared by income group provides interesting information on the similarities and differences of how the food choice process unfolds across varying income groups. The insights from this study are useful for the development of an updated, quantitative food choice questionnaire for application in this and other emerging economies.PMID:37591447 | DOI:10.1016/j.appet.2023.107001

Relevance of oil price, military expenditure and exports to achieve the Saudi Arabian sustainable economic and environmental objectives: a non-linear ARDL approach
This study investigates the economic and environmental issues of Saudi Arabia, a net exporter of crude oil mainly relying on oil exports, which faces economic crises due to the decline in oil prices. For this purpose, we highlighted the main challenges of the Saudi economy, such as oil price shocks and a significant increase in military expenditures. The economic and environmental issues are vital for the country's development and sustainability. Saudi Arabia is a major exporter of fossil fuels, which threatens its long-term economic growth due to the global transition towards renewables. Also, heavy dependence on fossil f...

A thiol-Michael approach towards versatile functionalized cyclic titanium-oxo clusters
Chemistry. 2023 Aug 16:e202302352. doi: 10.1002/chem.202302352. Online ahead of print.ABSTRACTIn expanding our research activities of superlattice engineering, designing new giant molecules is the necessary first step. One attempt is to use inorganic transition metal clusters as building blocks. Efficient functionalization of chemically precise transition metal clusters, however, remains a great challenge to material scientists. Herein, we report an efficient thiol-Michael addition approach for the modifications of cyclic titanium-oxo cluster (CTOC). Several advantages, including high efficiency, mild reaction condition, c...
