Anarchism in Korea: independence, transnationalism, and the question of national development, 1919-1984

A regional and transnational history of anarchism in Korea by Dongyoun Hwang. This book provides a history of anarchism in Korea and challenges conventional views of Korean anarchism as merely part of nationalist ideology, situating the study within a wider East Asian regional context. Following the movement after 1945, Hwang shows how anarchism in Korea was deradicalized and evolved into an idea for both social revolution and alternative national development, with emphasis on organizing and educating peasants and developing rural villages.

China builds strong ecological barrier with science-based desertification control

By Dong Siyu China has implemented multiple measures to combat desertification over the recent years, achieving fruitful results. The areas of land desertification and soil desertification were both reduced, and hazards of sandstorms and soil erosion were effectively curbed. As of the end of 2022, the country had completed desertification…

A review on lignin pyrolysis: pyrolytic behavior, mechanism, and relevant upgrading for improving process efficiency | Biotechnology for Biofuels and Bioproducts

Lignin is a promising alternative to traditional fossil resources for producing biofuels due to its aromaticity and renewability. Pyrolysis is an efficient technology to convert lignin to valuable chemicals, which is beneficial for improving lignin valorization. In this review, pyrolytic behaviors of various lignin were included, as well as the pyrolytic mechanism consisting of initial, primary, and charring stages were also introduced. Several parallel reactions, such as demethoxylation, demethylation, decarboxylation, and decarbonylation of lignin side chains to form light gases, major lignin structure decomposition to generate phenolic compounds, and polymerization of active lignin intermediates to yield char, can be observed through the whole pyrolysis process. Several parameters, such as pyrolytic temperature, time, lignin type, and functional groups (hydroxyl, methoxy), were also investigated to figure out their effects on lignin pyrolysis. On the other hand, zeolite-driven ligni
