Summary: The hyperbranched phosphorus-containing copper phthalocyanine compound (DOPO-CuPc) was synthesized and used as a flame-retardant additive for epoxy thermosets, significantly improving the flame retardant properties. The mechanism involved the release of phosphorus-containing radicals and gases in both the gas and condensed phases, contributing to the formation and stability of a protective char layer during combustion.

Summary: The quick identification of known organic low molecular weight compounds, also known as structural dereplication, is a highly important task in the chemical profiling of natural resource extracts. This article presents the results of structure searches carried out starting from 58 carbon-13 NMR data sets recorded on compounds selected in the metabolomics section of the biological magnetic resonance bank (BMRB). Two compound retrieval methods were employed, and both methods proved to be efficient and can be used together in a complementary way.

Summary: Biochar addition has a positive effect on soil organic carbon (SOC) content and soil quality improvement. However, the mechanisms and structural changes of soil humic substances under different types of biochar addition are poorly understood. This study compared the effects of rice husk, corn stalk, and tobacco stalk biochar on humus composition and humic acid (HA) structure in Northeast China. Results showed that corn stalk biochar significantly increased the fulvic acid (FA) content and simplified the HA structure, while tobacco stalk biochar was superior in soil carbon sequestration.

Summary: This study systematically investigates the quality of experimental C-13-NMR spectra published in the journal Molecules from 1996 to 2015 using CSEARCH technology. The results show that using the CSEARCH-Robot-Referee during peer review can prevent trivial assignment errors and wrong structure proposals. Comparison of key numbers with other journals in natural product chemistry indicates a similar level of quality among publishers.

Summary: There is a growing demand for humic substances, but coal-related resources, from which humic substances are extracted, are in short supply. Consequently, there is an interest in producing humic-like substances from lignocellulosic waste materials. In this study, tea waste was used to extract humic fractions, including purified humic-like acid and unpurified humic and fulvic acids. Comparative analyses were performed between these tea waste derived humic-like substances (TWDHLS) and commercially available humic acid (CHA) extracted from lignite. The results showed slight differences in elemental composition and FTIR properties, while NMR results indicated similar carbon distribution. TWDHLS exhibited a more recalcitrant nature due to the presence of stable compounds. The biological activity of TWDHLS was found to be comparable to that of CHA. These findings suggest that TWDHLS could be a potential plant biostimulant and a better substitute for humic substances.

Summary: This study reports a method of facilitating SO2/NO2 separation through NO2 dimerization. The NO2 dimerization is triggered by temperature and pressure, resulting in N2O4 with a larger molecular size, which inhibits N2O4 diffusion into the zeolite pore and achieves high separation selectivity. High performance SO2/NO2 separation was achieved on an SSZ-13 zeolite membrane.

Summary: The surface coating on a marble statue from the Renaissance period stored in Milan was studied and found to have a degradation layer composed of gypsum, likely due to exposure to outdoor environment and atmospheric pollution. Additionally, it was suggested that the chemical nature of the coating applied in the late 19th century could have contributed to the surface alteration.

Summary: Microanalysis techniques based on resonance Raman and reflection visible spectroscopy were used to characterize the pigments responsible for blue or violet coloration in flowers such as Lobelia erinus, Campanula portenschlagiana, Cineraria, Viola tricolor, Anemone coronaria, Agapanthus, Platycodon, Salvia farinacea, Plumbago capensis, Ceratostigma plumbaginoides, Commelina communis, and Salvia patens. The spectroscopic methods were applied both in vivo on the flower petals and in vitro on extracts obtained through solid-phase extraction. Different patterns in the Raman spectra were correlated with substitution schemes of anthocyanins' benzopyrilium nucleus and copigmentation forms responsible for blue color stabilization. The results were confirmed through comparison with analysis by liquid chromatography-electrospray ionization-mass spectrometry.

Summary: The recycling of waste mandarin peels into biochar (MRBC) has been used as a high performance and cost-effective adsorbent for treating polluted wastewater effluents. Batch adsorption studies were conducted to analyze the adsorption competency of MRBC on two dyes, methylene blue (MB) and basic fuchsin (BF), either in individual solutions or binary combinations. The results showed that MRBC was capable of effectively removing a high percentage of both dyes. However, the adsorption capacity decreased when the dyes were combined. The cost estimation of MRBC production and wastewater treatment indicated that both were relatively low.

The introduction of Sb3+ effectively reduced the band gap of the host material and enabled energy transfer pathway for Tb3+ emission. The doped Tb3+ ions resulted in the suppression of emission due to electron transfer. The Cs2NaInCl6: 2.5 %Sb3+, 40 %Tb3+ NCs exhibited superior sensitivity and selectivity for copper ions detection.

Summary: Raman spectroscopy is commonly used for studying glassy materials in cultural heritage, but it is more difficult to interpret the spectra and apply the technique with portable instruments. In contrast, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) can be used in archaeometric investigations as it is portable and non-invasive. However, there is limited application of this technique to historical glasses. This exploratory work demonstrates the potential of DRIFTS, in combination with portable X-ray Fluorescence (pXRF) and EDS microanalyses, for studying the composition and alteration of glass samples in cultural heritage.
