Although theoretical methods indeed do not use chemical reagents and do not produce laboratory waste, due to the complexity of calculations they often require a lot of energy and can generate a significant carbon footprint. In our opinion, the basic question is not “Should we take into account the carbon footprint of computational methods in their assessment?”, but “How to do it properly?” In this work, we have attempted to address this issue by using an RGB model, a well-known tool used for assessing analytical chemistry methods, that has been adapted to the specifics of computational chemistry (RGB_in-silico). The model uses three primary parameters: the calculation error (red), the carbon footprint resulting from the energy consumption of the computer (green), and the computation time (blue). In phase I, acceptability thresholds are adopted. Methods that are unacceptable in at least one aspect are rejected. In phase II methods are comprehensively compared in terms of “whiteness”. The model was validated on 24 quantum chemical methods for calculating NMR shielding constants, differing in functionals and basis sets. The obtained results indicate a huge discrepancy between the methods, and therefore, the need to use a dedicated tool for selecting the optimal one in a rational way. The large values of the carbon footprint clearly indicate that some computational methods cannot be considered as “green in nature”. The RGB_in-silico model seems to be a simple and useful metric.</div></div>","PeriodicalId":22138,"journal":{"name":"Sustainable Chemistry and Pharmacy","volume":"48 ","pages":"Article 102215"},"PeriodicalIF":5.8,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pretreatment was applied to partially convert furfural to furfuryl alcohol which facilitated the condensation of phenol with furfural, at temperatures >90<sup>o</sup>C.

Device fabrication involves placing a magnetic bar between the layers of octanol-supported cellulose, which allows direct immersion in diluted blood samples and its rotation in the magnetic field. The important parameters, such as pH, ionic strength, extraction/desorption rate, and time, were optimized systematically. Adsorption was optimized at 400 rpm for 30 min and then rapid back-extraction into 2 mL of ethyl acetate. The approach showed good linearity (0.1–5 μg mL<sup>−1</sup>), good extraction efficiency (92–112 % recovery), low LOQs (0.05–0.09 μg mL<sup>−1</sup>), and excellent intra-day/inter-day precision (3.5–13.4 %).

This study aims to conduct a comprehensive assessment of a novel lightweight PG-based brick (LPB), focusing on its engineering performance and environmental safety as a critical scientific evaluation prior to industrial application. The evaluation emphasizes the brick's service performance and safety characteristics. Additionally, the properties of the produced LPB were compared with three different types of commercial bricks, namely autoclaved aerated concrete (AAC) brick, cement sand brick (CSB), and red clay brick (RCB). The results demonstrate that LPB exhibits compressive strength (5.2 MPa) comparable to that of AAC bricks and CSB, along with good water resistance. Although LPB has a lower compressive strength than RCB, its lightweight nature (890 kg/m<sup>3</sup>) offers distinct advantages. Furthermore, the leachability of heavy metals from LPB, as well as the content of radionuclides in LPB, are below the limits outlined in GB 5085.3–2007 and GB 6566-2010, respectively.
