Recently, the 5GH team found abnormal error bars from figure 4-7 of the article [1]. The lengths of the error bars in each figure are identical.
Recently, we found some abnormal infrared spectra reported in biochar researches. Parts of these spectra have similar (or nearly the same) but small signals (please find the examples below). If they are real signals from the samples, what were their origin? The studies did not give any explanation about it. Or if they are noises, do these similar/same noises suggest copy-past from one to the other? The 5GH welcome input at 5GH@5gh.org.cn
Recently, the 5GH team found some unusual authorship pattern on ZHOU's papers.
The article have 75 references. Among them, 13 references were co-authored by A. V. Trukhanov, who is also a author of the article.
The article provides the information about the hospitalization costs for elderly (over 65 years old) trauma patients in Baotou, between January 2017 and March 2022. These data is of great interest not only to the scientific community but also to the policy markers, who are leading the reform of the health system. However, the communities may be better informed if the authors could further address the following issues
Recently, the 5GH team found abnormal parts of the infrared spectra (Figure 6) on the article.
Recently, the 5GH team found abnormal parts in the XRD patterns on paper, as shown below. It is not clear that these abnormalities were resulted from manipulation or publication processing, such as compressing the images during the manuscript preparation.
Recently, the 5GH team found abnormal data on the Table 1 of the article. The standard deviations on that table seem to be too small.
Recently, the 5GH team found abnormalities on the XRD patterns of the article
The XRF patterns on the Figure 9 of the article are identical to each other.
The Figure 1(b) on the article [1] was likely manipulated.
Concerns are raised about the turnover time (from submitted to accepted) for Golubnitschaja's publications on EPMA Journal, where she also plays the role of Editor in Chief.
