Ozone concentration prediction using machine learning models integrated with 115 volatile organic compound measurements and dimensionality reduction techniques

Ecotoxicology and Environmental Safety
High-quality prediction of ozone concentrations is essential for formulating effective environmental policies. The integration of monitoring data of volatile organic compounds (VOCs), key precursors in ozone formation, through dimensionality reduction ...

Fragmented or Unified? The State of China’s Carbon Emission Trading Market

Energies, 2023
China has adopted a gradualism principle in establishing its carbon emission trading system from the regional pilot markets to a national one. In view of the huge market potential and large differences across China, this paper applies the cointegration ...

Study on the Corrosion Behavior of Austenitic Steel HR3C in Supercritical Carbon Dioxide at 550 and 600 °C

Metals
The corrosion behavior of austenitic steel HR3C in supercritical CO2 at 550–600 °C under 25 MPa for 1000 h was investigated. The corrosion kinetics of HR3C were evaluated using weight change measurements.

Cookstoves illustrate the need for a comprehensive carbon market

Environmental Research Letters, 2015
Existing carbon offset protocols for improved cookstoves do not require emissions testing. They are based only on estimated reductions in the use of non-renewable biomass generated by a given stove, and use simplistic calculations to convert those fuel ...

Evaluation and obstacle degree analysis of low-carbon development level in Fujian province–based on entropy weight TOPSIS method

Frontiers in Energy Research, 2022
With the introduction of “dual carbon” goals of “peaking its carbon emissions before 2030 and achieving carbon neutrality by 2060" and the gradual promotion of the carbon trading market, it is the main trend to achieve low-carbon and clean development in

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
