Techniques such as mass spectrometry and NMR spectroscopy form an essential part of the medicinal chemist's toolbox for characterizing and assessing the purity of new molecules. Empowering medicinal chemists to gain early insight into their reaction products has a direct impact on productivity. Devolution of cutting-edge techniques from the specialist to the bench chemist also frees the specialist to concentrate on solving the more demanding of analytical problems. For open-access techniques to be taken up, they must be robust and be able to handle differing sample concentrations and varying sample complexities. This paper details the implementation of high-resolution liquid chromatography/mass spectrometry in open access to aid the medicinal chemist in characterizing desired products and identifying unexpected rearrangements, by-products and complete unknowns.

The urgent need to address the growing problem of antimicrobial resistance in multidrug-resistant bacteria requires the development of pioneering approaches to treatment. The present study aims to evaluate the antimicrobial potential of the essential oils (EOs) of Moringa oleifera (moringa), Cinnamomum verum (cinnamon), and Nigella sativa (black seed) and the synergistic effect of the mixture of these oils against Staphylococcus aureus MCC 1351. Statistical modeling revealed cinnamon oil had the highest individual antimicrobial potency, followed by black seed oil.

Finding ways to produce dense and smooth perovskite films with negligible defects is vital for achieving high-efficiency perovskite solar cells (PSCs). Herein, we aim to enhance the quality of the perovskite films through the utilization of a multifunctional additive in the perovskite anti-solvent, a strategy referred to as anti-solvent additive engineering. Specifically, we introduce ortho-substituted-4'-(4,4″-di-tert-butyl-1,1':3',1″-terphenyl)-graphdiyne (o-TB-GDY) as an AAE additive, characterized by its sp/sp-cohybridized and highly π-conjugated structure, into the anti-solvent.

Department of Chemistry, The University of North Texas, Denton, Texas, USA.
Rationale: Fentanyl and fentanyl analogs continue to pose a serious threat to the public health. The vast number of fentanyl analogs emerging on the black-market call for optimized analytical methods for the detection, analysis, and characterization of these extremely dangerous drugs.
Methods: Atmospheric pressure solids analysis probe (ASAP) mass spectrometry was used for the rapid analysis of 250 synthetic opioid standards, including 211 fentanyl analogs, 32 non-fentanyl related opioids, and 8 fentanyl precursors.

Infants are particularly vulnerable to exposure to toxic trace elements due to their developmental stage and behaviors such as mouthing and chewing on toys. Chemical exposure to heavy metals in infants' toys is a significant concern as it poses a threat to their health and well-being. Therefore, quality control measures are essential to prevent infants' exposure to potentially harmful metals.

The impact of lead and cadmium exposure on subclinical cardiovascular disease (CVD), indicated by elevated high-sensitivity cardiac troponin (hs-cTnT) and N-terminal pro b-type natriuretic peptide (NT-proBNP) remains uncertain. We analyzed data from participants aged 20 and older, without overt CVD, in the National Health and Nutrition Examination Survey (NHANES; 1999-2004). Elevated lead and cadmium levels were defined as 3.
