“…Incorporation of plant residues and organic fertilizers into soil brings about some secondary chemicals, e.g., alkaloids, terpenoids, cardenolides, glucosinolates, and oxalates (Zhang et al, 2020 ), and their metabolites such as monoaromatics (e.g., BTEX and phenol) and polycyclic aromatics (e.g., naphthalene, dioxin, and steroids) (Chen et al, 2017 ; Steinmetz et al, 2019 ). These compounds often exert deleterious effects to soil-dwelling pupae when accumulated to high concentrations within the bodies.…”

“…These additives generate a variety of organic compounds incorporated into agricultural soil (Kumar and Goh, 2000;Hanselman et al, 2003;Kjaer et al, 2007). Among these organic pollutants are monoaromatics, for instance, benzene, toluene, ethylbenzene, xylene (collectively known as BTEX), styrene, and phenol and polycyclic aromatics such as naphthalene, dioxin, and steroids (Chen et al, 2017;Steinmetz et al, 2019). Some aromatics are toxic, antinutritive, or/and repellent at high concentrations (Ceja-Navarro et al, 2015;Hammer and Bowers, 2015;Vilanova et al, 2016;Berasategui et al, 2017).…”

To avoid potential harm during pupation, the Colorado potato beetle Leptinotarsa decemlineata lives in two different habitats throughout its developmental excursion, with the larva and adult settling on potato plants and the pupa in soil. Potato plants and agricultural soil contain a specific subset of aromatics. In the present study, we intended to determine whether the stage-specific bacterial flora plays a role in the catabolism of aromatics in L. decemlineata. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the operational taxonomic units (OTUs) obtained by sequencing of culture-independent 16S rRNA region enriched a group of bacterial genes involved in the elimination of mono- and polycyclic aromatics at the pupal stage compared with those at the larval and adult periods. Consistently, metabolome analysis revealed that dozens of monoaromatics such as styrene, benzoates, and phenols, polycyclic aromatics, for instance, naphthalene and steroids, were more abundant in the pupal sample. Moreover, a total of seven active pathways were uncovered in the pupal specimen. These ways were associated with the biodegradation of benzoate, 4-methoxybenzoate, fluorobenzoates, styrene, vanillin, benzamide, and naphthalene. In addition, the metabolomic profiles and the catabolism abilities were significantly different in the pupae where their bacteria were removed by a mixture of three antibiotics. Therefore, our data suggested the stage-dependent alterations in bacterial breakdown of aromatics in L. decemlineata.

“…Since TMAH is one of the most popular thermochemolysis reagents [14], the studies about TMAH thermochemolysis have been reviewed for its application on the analyses of humic acids [52,84,90,102,103], humic-like substances [104e107], fatty acids [82,88,102,108], phenolic compounds [16,19,81,109], amino acids [64,110], aromatic and aliphatic compounds [29,111], and carbamates [112]. In addition, TMAH is not only a thermochemolysis reagent but is also used as an effective silicon etching solvent [113e115], for dissolution of E. crypticus [116], as a strong base catalyst for transesterification [117], as an extraction solvent for mercury [42,118e121], and Sulfur atom detection [17,122], as a dispersant [123], as a balance-fluid in the fabrication of functionalized-porosity layered-ceramics processes [124], as a digestion solvent for biological samples [125,126], for pH adjustment of solutions [127,128], and for extraction of different halogen elements in soils, such as fluorine [129], chloride [130,131], bromine [132,133], and iodine [134e137].…”

Tetramethylammonium hydroxide (TMAH) is one of the most popular methylation reagents that have been increasingly used for the detection of organic compounds within a wide range of samples, such as soil, coal, lacquer, lignin, polymers and for in situ analysis of solid samples by space experiments. The analytical methods and instruments, experimental conditions, and the qualitative and quantitative analysis of organic compounds using TMAH thermochemolysis for the last 10 years were reviewed; additionally, the mechanism of TMAH thermochemolysis and TMAH degradation are overviewed herein. The objective of this paper is to give a broad view of the TMAH thermochemolysis analysis, to demonstrate how the technique can be used for the detection of organics on Mars and other planets, and to promote cooperation between different disciplines which may use thermochemolysis.

“…It is worth assuming a photobleaching of the colloids as a factor contributing to the observed quenching, since photo-oxidation of phenol derivatives 49,50 can facilitate the degradation of the complexes during the luminescence measurements at different temperatures, where the samples are exposed to the irradiation for a long time (about twenty-thirty minutes). However, PSS-[Tb 2 (TCAn) 2 ] (n = 1, 2) should be irradiated within two hours at least for the degradation of the luminescence on 20-30% relative to the initial value, which is much longer than the irradiation time for the heating-cooling cycle.…”

The work introduces hydrophilic PSS-[Tb2(TCAn)2] nanoparticles to be applied as highly sensitive intracellular temperature nanosensors. The nanoparticles are synthesized by solvent-induced nanoprecipitation of [Tb2(TCAn)2] complexes (TCAn - thiacalix[4]arenes bearing different upper-rim substituents: unsubstituted TCA1, tert-buthyl-substituted TCA2, di- and tetra-brominated TCA3 and TCA4) with the use of polystyrenesulfonate (PSS) as stabilizer. The temperature responsive luminescence behavior of PSS-[Tb2(TCAn)2] within 293–333 K range in water is modulated by reversible changes derived from the back energy transfer from metal to ligand (M* → T1) correlating with the energy gap between the triplet levels of ligands and resonant 5D4 level of Tb3+ ion. The lowering of the triplet level (T1) energies going from TCA1 and TCA2 to their brominated counterparts TCA3 and TCA4 facilitates the back energy transfer. The highest ever reported temperature sensitivity for intracellular temperature nanosensors is obtained for PSS-[Tb2(TCA4)2] (SI = 5.25% K−1), while PSS-[Tb2(TCA3)2] is characterized by a moderate one (SI = 2.96% K−1). The insignificant release of toxic Tb3+ ions from PSS-[Tb2(TCAn)2] within heating/cooling cycle and the low cytotoxicity of the colloids point to their applicability in intracellular temperature monitoring. The cell internalization of PSS-[Tb2(TCAn)2] (n = 3, 4) marks the cell cytoplasm by green Tb3+-luminescence, which exhibits detectable quenching when the cell samples are heated from 303 to 313 K. The colloids hold unprecedented potential for in vivo intracellular monitoring of temperature changes induced by hyperthermia or pathological processes in narrow range of physiological temperatures.
