Hyperprolific and hypercited authors
Table 3 shows the number of highly cited papers (HCP) on biochar for specific authors, as well as their total number of HCP.
Yong Sik Ok has contributed to 92 HCP on biochar out of a total of 114 HCP, indicating a significant presence in the field. Similarly, Dan Tsang has authored 66 HCP on biochar out of a total of 90 HCP, further highlighting their significant contributions.
Bin Gao has contributed to 46 HCP on biochar out of a total of 56 HCP, indicating a focused research interest in this area. Joerg Rinklebe has also contributed to 46 HCP on biochar, with a total of 63 HCP, suggesting a strong presence in the field. Notably, Guangming Zeng has a substantial contribution of 46 HCP on biochar, but an exceptionally high total of 199 HCP, which suggests a wide range of research interests beyond biochar. Johannes Lehmann from Cornell University was previously identified as having the largest citation in biochar is now dethroned by Yong Sik Ok and Dan Tsang.
The numbers of highly cited papers (HCP) by some authors in the field of biochar appear to be unusually high and potentially unrealistic. For example, Yong Sik Ok, who published copiously has on average 11 highly cited papers per year.
