**Preface to "Biomass—A Renewable Resource for Carbon Materials"**

Currently, humanity is indeed in turbulent times. The current world affairs are no different from those during World War I (28th July 1914–11th November 1918) or during the time of World War II (1st September 1939–2nd September 1945). Scientists, especially, chemists, have a vital role to ensure that lifesaving materials are available at the disposal of common people. Renowned German chemist Raphael von Ostrejko has a few patents based on activated carbon from biomass during 1900–1920 and his inventions based on those patents, namely activated carbon based masks, saved many people from perishing due to the harmful effects of poisonous gases used during World War I. Carbon materials from biomass, in particular, are equally significant during these testing times of war, energy and food shortages and climate change. Biomass constitutes a rich source of carbon materials with diverse properties and applications impacting almost every sphere of human activity, ranging from agriculture, health, energy, environment, materials, safety, security, defence and many more. All the three vital components of biomass, namely cellulose, hemicellulose and lignin, offer unique structure and morphological features to the resulting carbon materials. Owing to the sustainability, diversity in properties and applications of these carbon materials produced from biomass, it is conceived that a Special Issue needed to be launched in the journal "C-journal of carbon research" published by Multidisciplinary Digital Publishing Institute (MDPI), wherein the latest scientific advancements throughout the globe could be assembled and made available freely, at a click, to the scientific, academic and industrial fraternity for their growth and development. Thus, this Special Issue was launched with the title "Biomass—A renewable resource for carbon materials". Indeed, the attempt has been a great success due to the untiring and visionary approach of the managing editor Dr William Wang. Within a short duration of 4.5 months (4/8/2022 to 20/12/2022), we succeeded in publishing 10 state of the art research papers on diverse applications of carbon materials, namely, agriculture, energy, environment and medicine. The editors of this Special Issue place on record their indebtedness to the 10 research groups that have contributed 10 outstanding papers to the Special Issue, facilitating the conversion of the Special Issue to a published reference book on carbon materials with 10 chapters.

Finally, I bow down before my LORD and Saviour Jesus Christ for His all sufficient grace that enabled His servant to succeed in this scientific pursuit.

Dedicated to My Lord and My God Jesus Christ. My grace is sufficient for thee. (2 Corinthians 12:9).
