Summary: Pyranofuroquinoline and pyranofurocoumarin derivatives are important compounds with diverse applications. These compounds can be synthesized in one step by radical cyclization reaction with the presence of manganese(III) acetate. The electronic and optical features of the compounds were studied using theoretical approaches, and their excitation and emission spectrums were computed. The results showed that the pyranofuroquinoline molecules did not exhibit energy transfer feature, and the nonlinear optic behavior of furoquinoline was higher than that of pyranofuroquinoline and furocoumarin. Furthermore, the investigated pyranofuroquinoline and pyranofurocoumarin compounds showed higher activity than anticancer and antibacterial standards according to calculated docking parameters.

Summary: This study investigated the oxidative removal of Mn(II) by peroxymonosulfate (PMS). It was found that PMS is a more efficient oxidant than chlorine for Mn(II) oxidation. The oxidation of Mn(II) by PMS consists of both homogeneous and heterogeneous processes. Complexion with ligands and coexisting metal ions can greatly affect the oxidation rate and mechanism of Mn(II). The results highlight that PMS oxidation is an attractive alternative technology for Mn(II) removal and provide a fundamental understanding of Mn materials-based advanced oxidation processes.

Summary: The La/Ce(0.5)Mn(0.5) catalyst prepared by wetness impregnation showed high activity and stability in the catalytic oxidation of ethyl acetate, converting it into CO2 with high efficiency. The intermediates identified were mainly ethanol and acetaldehyde, with concentrations below certain levels. The dissociative adsorption modes of ethyl acetate on the catalyst surface were found to be related to the surface oxygen species, affecting the stability and selectivity of the catalyst.

Summary: [Mn3O(OAc)(7)(HOAc)](6)·xAcOH (x=6-9) is a rare compound containing molecular Mn-18 rings. The Mn-18 rings are formed by Mn-3(mu(3)-O) subunits, in which high-spin Mn(III) centers are bridged by acetate anions (AcO-) pairs. The magnetic measurements show weak ferromagnetic interactions between the Mn-3 units within the Mn-18 rings, which can be simulated as basically uncoupled magnetic moments of each Mn-3 unit within the ring.

Summary: This study utilized colorimetric methods to determine manganese(III)-pyrophosphate complex at trace levels, and developed an ozonation method to measure dissolved Mn concentrations. Different compounds such as oxalic acid, EDTA, humic acid, and desferrioxamine B were found to have varying effects on the oxidation of bisphenol A and hydroquinone by Mn compounds. Additionally, a Mn(VII)-reducer-PP system showed potential for the transformation of phenolic compounds in polluted water treatment.

Summary: This study investigated the yield, kinetics, stoichiometry, and abatement of trace organic contaminants (TrOC) by the permanganate/bisulfite (MS) and permanganate/manganous (MM) processes. The results showed that the TrOC abatement rate in the MS process was significantly higher than that in the MM process, despite the higher rate constant of Mn(III) generation in the former. The contribution of Mn(III) to TrOC abatement was limited in both processes.

Summary: This study presents a convenient synthesis of highly-substituted dihydrofurans, which can be converted into various acetals using Mn(III) oxidation. The key point lies in the cyclization of resonated vinylpentanedione radicals to form acetoxydihydrofurans, which can then be transformed into hemiacetals and acetals with good yields under mild conditions.

Summary: Stable chromium isotopes have been used as a paleoredox proxy to track atmospheric oxygenation, with previous belief that Cr oxidation is limited to terrestrial settings. However, recent research shows rapid marine Cr(III) oxidation linked to microbial Mn(II) oxidation, challenging the traditional view. Initial partial oxidation of Cr(III) to Cr(VI) can cause a small isotope fractionation, calling for a reevaluation of the link between Cr isotope values and atmospheric oxygenation.

Summary: This study successfully developed a high-performance anode free from Mn(II) dissolution by smartly confining manganese monoxide into nitrogen-rich carbon nanosheets, achieving high specific capacitance and excellent cycling stability, which can be used in aqueous asymmetric supercapacitors (ASCs). The ASC with this anode delivers a remarkably high specific energy, outperforming products with carbon anodes.

Summary: This study compared the differences between the volume-based method and the weight-based method in capsule compounding, and found that the weight-based method performed better in terms of capsule quality. Although the weight-based method requires knowledge of the parameters of the active pharmaceutical ingredient and excipients, it is preferred.

Summary: Erythromycin, a macrolide antibiotic, is often used off-label as a prokinetic agent in premature neonates, but there is no suitable oral formulation for these high-risk patients. In this study, clinical trials of erythromycin as a prokinetic agent were reviewed, and 20 mg capsules of erythromycin were compounded with microcrystalline cellulose. The stability of the 20 mg erythromycin capsules stored at room temperature and protected from light was tested for one year, and the capsules were found to have a beyond-use date of at least one year.
