Retraction: Preparation and Characterization of Mesoporous Silica from Bagasse Bottom Ash from the Sugar Industry (Crystals, (2021), 11, (938), 10.3390/cryst11080938)

Abstract

The journal retracts the article “Preparation and Characterization of Mesoporous Silica from Bagasse Bottom Ash from the Sugar Industry” [1], cited above. Following publication, the Crystals Editorial Office were made aware that the published paper [1] overlaps significantly with a previously published paper [2]. Adhering to complaint procedures, an investigation was conducted that confirmed the extent of the overlap in the structure of the paper, headlines, methodology, results and discussion. Although the values in the figures and table are different, hinting at the investigation of different samples, the paper published in Crystals [1] reports some identical results (the specific surface area and purity of the mesoporous silica) to the previously published paper [2]. The article is therefore retracted in agreement with the authors. This retraction was approved by the Editor-in-Chief of the journal.
