AbstractEthylene glycol, a widely used chemical, has a large global capacity exceeding 40 million tons per year. Nevertheless, its production is heavily reliant on fossil fuels, resulting in substantial CO2 emissions. Herein, we report an approach for electrochemically producing ethylene glycol from biomass glycerol. This process involves glycerol electrooxidation to glycolaldehyde at anode, which is subsequently electro-reduced to ethylene glycol at cathode.

1 Introduction The development of coal mining technology and equipment has led to a significant increase in the speed of mining face advancement, with equipment largely achieving mechanization and progressing towards automation and intelligence [1-3]. However, the speed of rock roadway excavation in coal mines remains low, typically between 100 m to 200 m per month, resulting in a significant imbalance between mining and extraction [4-6].

5. Estimation Results and Discussion 5.1. Benchmark Regression ResultsTo account for city-specific differences and temporal effects, and to more precisely capture the relationships among the variables, we employed a fixed-effects model. The benchmark regression results are presented in Table 2. The dependent variables in columns (1) and (2) are based on patent grants. Column (1) presents the regression results without control variables, while column (2) includes relevant control variables.

Bamboo vinegar is “the condensed liquid of bamboo obtained in a high-temperature oxygen-free environment.” Its composition includes over 200 organic chemical constituents, primarily organic acids, phenols, ketones, alcohols, and esters, with acetic acid serving as the principal component." A study conducted by researchers from Central South University of Forestry and Technology in Changsha, China has suggested that it has potential as an anti-acne solution when paired with activated bamboo...
