In this study, the development of a user-friendly, cost-effective, and alternative method for diagnosing <i>H. pylori</i> infections by detecting NH₃ in exhaled breath is reported. A commercial disposable pH strip is modified with sodium carboxymethylcellulose to enhance its performance in gaseous environments. The modified pH strip exhibits compatibility with both acidic (HCl and CH₃COOH) and alkaline (NH₃) gases. Furthermore, the sensor monitors the production of NH₃ resulting from fish spoilage for 72 h, highlighting its real-time capabilities.

Hydrogen is currently a crucial reagent for vital industries such as petrol desulfurization, iron reduction and ammonia production, so the decarbonization of its production is a major challenge. CuMnO₂ (CMO), a p-type semiconductor, has been shown to enhance the efficiency of catalysts such as TiO₂ for the photoelectrocatalytic water splitting reaction. However, since pure CMO thin films have never been reported, its potential and limitations remain elusive. We used spray pyrolysis as a low-cost synthesis technique to simplify and accelerate the synthesis of CMO thin films directly on FTO substrates.

In this study, to evaluate the anticancer and antiviral properties of EER (Glu-Glu-Arg), EPR (Glu-Pro-Arg), and PRP (Pro-Arg-Pro) tripeptides, firstly their conformation preferences were searched, and the most stable optimized structure of each tripeptide was determined, using the molecular mechanics force field (MMFF) method and the Spartan06 program. Afterwards, each tripeptide was docked to SARS-CoV-2 spike protein receptor-binding domain (6M0J), SARS-CoV-2 main protease (6M03, 6LU7), spike glycoprotein (6VXX), DNA (1BNA), integrins (4WK0, 3ZDX, 1JV2) and epidermal growth factor receptor tyrosine kinase (4HJO). Moreover, molecular dynamics (MD) simulations were performed to validate the stability of the EER, EPR and PRP tripeptides docked to SARS-CoV-2 main protease, M^Pro (6M03) and epidermal growth factor receptor tyrosine kinase (4HJO) within 100 ns time scale and ligand-receptor interactions were evaluated. The metrics root-mean-square deviation, root-mean-square fluctuation, intermolecular hydrogen bonding, and radius of gyration revealed that the EER, EPR, and PRP tripeptides form energetically stable complexes with the target proteins.

The average size of the prepared B,N,S-CDs is 2.7 ± 0.7 nm, and the high photoluminescence quantum yield is 67.6%. Furthermore, due to the efficient quenching effect of Hg²⁺, such B,N,S-CDs are considered to serve as an efficient fluorescence sensing platform for label-free and sensitive detection of Hg²⁺ with a detection limit of 72 nM. The selectivity experiments reveal that the B,N,S-CDs are selective and specific for Hg²⁺ even in the presence of other interfering substances. Most importantly, the Hg²⁺ sensing platform based on B,N,S-CDs can be successfully applied to the determination of Hg²⁺ in tap water and real lake water samples.

Given the profound impact of chalcogen element doping, our primary focus lies in investigating the excited state behaviors of BTD-O, BTD-S, and BTD-Se fluorophores. Through simulations encompassing variations in geometry and vertical excitation charge reorganization, we unveil atomic-electronegativity-dependent hydrogen bonding interactions and photoexcitation-induced charge recombination that can significantly augment the intramolecular double proton transfer (ESDPT) reaction in the excited state for BTD-O, BTD-S, and BTD-Se fluorophores. By constructing potential energy surfaces and identifying transition state forms, we elucidate the ultrafast stepwise ESDPT mechanism facilitated by the low potential barriers.
