We present our research findings related to new formulations of the organic additives (grinding aids) needed for the efficient grinding of inorganic solids. Even though the size reduction phenomena of the inorganic solid particles in a ball mill is purely a phys. process, the addition of grinding aids in milling media introduces a complex physicochem. process. In addition to further gain in productivity, the organic additive helps to reduce the energy needed for grinding, which in the case of cement clinker has major environmental implications worldwide. This is primarily due to the tremendous amounts of cement produced and almost 30% of the associated elec. energy is consumed for grinding. In this paper, we examine the question of how to optimize these grinding aids linking mol. insight into their working mechanisms, and also how to design chem. additives of improved performance for industrial comminution.

Bai, Xinxin published the artcileRemediation of phenanthrene contaminated soil by coupling soil washing with Tween 80, oxidation using the UV/S₂O₈^2- process and recycling of the surfactant, Application of 1-Hydroxy-2-naphthoic acid, the publication is Chemical Engineering Journal (Amsterdam, Netherlands) (2019), 1014-1023, database is CAplus.

Surfactant-enhanced soil washing was applied to phenanthrene (PHE)-polluted soil, followed by a sulfate radical-based advanced oxidation process. Soil washing experiments were conducted using the nonionic surfactant Tween 80 (TW 80), assessing the effect of washing temperature, TW 80 concentration, and liquid:soil ratio on PHE removal. Maximum PHE removal (90.0%) was achieved with 15 g/L TW 80 and a 10:1 (mL/g) liquid:soil ratio at 20°. A UV/S₂O₈^2- process was used to selectively oxidize PHE in the effluent and recover TW 80. The regenerated effluent was re-used for soil washing; results showed PHE removal efficiency was nearly the same as with fresh surfactant solution The UV/S₂O₈^2- oxidation reaction was also assessed, including possible intermediate products detection by liquid chromatog./mass spectrometry; a corresponding degradative pathway of target pollutants was proposed. Overall result indicated toil washing with TW 80 and subsequent selective UV/S₂O₈^2- oxidation may provide a potential option to remediate polycyclic aromatic hydrocarbon-polluted soil.

Qiu, Qianqian published the artcileDesign, synthesis, and biological evaluation of novel FXR agonists based on auraptene, Related Products of alcohols-buliding-blocks, the publication is Bioorganic Chemistry (2021), 105198, database is CAplus and MEDLINE.

Farnesoid X receptor (FXR) has been considered as an attractive target for metabolic disorder and liver injury, while many current FXR agonists suffer from undesirable side effects, such as pruritus. Therefore, it is urgent to develop new structure types different from current FXR agonists. In this study, a series of structural optimizations were introduced to displace the unstable coumarin and geraniol scaffolds of auraptene (AUR), a novel and safe FXR agonist. All of these efforts led to the identification of compound 14 (I), a potent FXR agonist with nearly fourfold higher activity than AUR. Mol. modeling study suggested that compound 14 fitted well with binding pocket, and formed the key ionic bond with His291 and Arg328. In acetaminophen-induced acute liver injury model, compound 14 exerts better therapeutic effect than that of AUR, which highlighting its pharmacol. potential in the treatment of drug-induced liver injury.

Kim, Dongjoo published the artcileHealth-beneficial aroma and taste compounds in a newly developed kombucha using a Huanglongbing-tolerant mandarin hybrid, SDS of cas: 106-25-2, the publication is Journal of Food Science (2022), 87(6), 2595-2615, database is CAplus and MEDLINE.

Huanglongbing (HLB) is a destructive citrus greening disease; no com. applicable measures exist. ‘LB8-9’ Sugar Belle (SB), originally developed for the fresh market, is the most HLB-tolerant cultivar among com. available varieties. Due to the limited capacity of the fresh fruit market, there is a need to increase the demand for SB juice. Kombucha is a fermented tea beverage with black tea and sugar, and is considered a healthy drink with an increasing market. Therefore, we aim to study the potential of using SB juice in kombucha production Regular (black tea with no citrus juice added), Hamlin (black tea with Hamlin juice added), and SB kombucha (black tea with SB juice added) were prepared and analyzed to observe the composition of aroma and taste compounds in the kombuchas. Aroma and taste compounds in the kombuchas were analyzed using gas chromatog.-mass spectrometry/olfactometry and liquid chromatog.-triple quadrupole mass spectrometry, resp. For aroma compounds, SB kombucha was characterized by high concentrations of terpenes and their derivatives, which have mandarinlike aroma characteristics and health benefits such as antidiabetic and antioxidant effects. For taste compounds, SB kombucha contained higher amount of fructose and organic acids, which have the potential to increase the intensity of sweetness and sourness, and flavonoids. This would support the potential benefits of using SB to make kombucha. This study provides valuable information about the aroma and taste compounds in SB kombucha and its potential health benefits, compared with regular and Hamlin kombucha.

Shen, Jiazhi published the artcileMetabolite profiling of tea (Camellia sinensis L.) leaves in winter., COA of Formula: C6H10O7, the publication is Scientia Horticulturae (Amsterdam, Netherlands) (2015), 1-9, database is CAplus.

Tea (Camellia sinensis L.) is a thermophilic evergreen woody perennial. It is poor in cold tolerance during winter. Changes occurred at metabolite level in low temperatures were poorly understood in tea plants. In this study, Metabolite profiling of tea leaves was performed to investigate the responses of tea plants to different cold conditions by using gas chromatog.-mass spectrometry (GC-MS) and multivariate anal. A total of 105 metabolites were identified. Principal component anal. (PCA) revealed that the tea leaves in plastic greenhouse (DP) and natural condition (OA) were clearly separated by their sampling times and growth conditions. The levels of changed metabolites could be organized in four clusters by hierarchical clustering anal. (HCA). According to the pathway, raffinose, maltose, glucose and fructose derived from the hydrolysis of sucrose were all more abundant in leaves of OA than those of DP. Despite temperature fluctuation, leucine, valine, threonine, alanine were all in higher level in leaves of DP than those of OA except Nov. 16. Citric acid, fumaric acid and malic acid were in higher level under the higher temperature in DP. Shikimic acid and quinic acid presented an absolutely distinct metabolism pattern. Shikimic acid was neg. correlated with quinic acid in both treatments except Mar. 16. They were at high level on Nov. 16, and then decreased sharply in the following periods in both treatments during the experiment The results indicated that the different low temperatures had significantly different effects on tea plants and could change their metabolic pathways in different ways. These might be helpful to understand the mechanism of cold resistance of tea plants at the metabolite level and to facilitate the future research on gene and protein expression in tea plants of DP and OA in winter.

Dai, Yuxuan published the artcilePhotocatalytic degradation mechanism of phenanthrene over visible light driven plasmonic Ag/Ag₃PO₄/g-C₃N₄ heterojunction nanocomposite, Related Products of alcohols-buliding-blocks, the publication is Chemosphere (2022), 133575, database is CAplus and MEDLINE.

Visible light driven plasmonic Ag/Ag₃PO₄/g-C₃N₄ heterojunction nanocomposite with regular morphol. was prepared via a modified facile method. The two-dimensional ultrathin g-C₃N₄ nanosheet is uniformly wrapped on the surface of Ag₃PO₄ nanopolyhedron. A charge transfer bridge was built between Ag₃PO₄ nanopolyhedron and g-C₃N₄ nanosheet due to the reduction of Ag nanoparticles. This structure can inhibit the recombination of photogenerated electron-hole pairs and promote the transfer of photogenerated carriers, so as to produce more active species for participating in the photocatalytic reaction. In addition, the surface plasmon resonance (SPR) of appropriate Ag nanoparticles enhanced the absorption and utilization of visible light. Compared with Ag₃PO₄ and Ag/Ag₃PO₄, Ag/Ag₃PO₄/g-C₃N₄ showed higher photocatalytic activity. Under visible light irradiation, the degradation rate of phenanthrene (PHE) was 0.01756 min^-1, which was 3.14 times and 2.38 times that of Ag₃PO₄ and Ag/Ag₃PO₄, resp. After four cycles of photocatalytic reaction, the Ag/Ag₃PO₄ /g-C₃N₄ photocatalyst still maintained high photocatalytic activity. The active sites of PHE were predicted by Gaussian simulation calculation and combined with intermediate products identification of GC-MS, the possible degradation pathway of PHE was speculated. This research has reference significance for the construction of plasmonic heterojunction photocatalyst in the field of environmental pollution remediation.

Mao, Yong published the artcileEffect of TIPA/TEA combined grinding aid on the behavior of quartz flotation in DDA system, Category: alcohols-buliding-blocks, the publication is Powder Technology (2022), 117570, database is CAplus.

In this paper, different dosages of TIPA, TEA and their combined grinding aid were added to the process of quartz grinding and their influence on the grinding efficiency and flotation recovery in DDA system was investigated. From the grinding and flotation experiments, It can be known that the effect of the combined grinding aid was better than that of a single reagent, which can not only significantly improve the grinding efficiency of quartz, but also increase the recovery of quartz from flotation. Based on the results of FT-IR spectroscopy, XPS anal., quantum chem. and solution chem. calculations, it can be seen that the hydroxyl groups in the TIPA/TEA combined grinding aid formed hydrogen bonds with O on the (101) surface of quartz, while collector DDA was mainly electrostatically adsorbed on the surface of quartz with neg. potential, and the introduction of combined grinding aid improved the adsorption of DDA, the grinding aid and collector played a synergistic role instead of competitive adsorption. The detection of contact angle and surface tension showed that the combined grinding aid can improve the hydrophobicity of quartz, reduce the surface tension and CMC value of DDA, and enhance the dispersibility of quartz, therefore, it can increase the recovery of quartz from flotation.

Yang, Hao published the artcileIdentification of cerebrospinal fluid metabolites as biomarkers for neurobrucellosis by liquid chromatography-mass spectrometry approach, COA of Formula: C8H8O3, the publication is Bioengineered (2022), 13(3), 6996-7010, database is CAplus and MEDLINE.

Neurobrucellosis is the most morbid form in brucellosis disease. Metabolomics is an emerging method which intends to explore the global alterations of various metabolites in samples. We aimed to identify metabolites in cerebrospinal fluid (CSF) as biomarkers that were potentially unique for neurobrucellosis. CSF samples from 25 neurobrucellosis patients and 25 normal controls (uninfected patients with hydrocephalus) were collected for metabolite detection using liquid chromatog.-mass spectrometry (LC-MS) approach. Inflammatory cytokines in CSF were measured with ELISA (ELISA). The base peak chromatogram in CSF samples showed that small-mol. metabolites were well separated Principal Component Anal. (PCA) anal. exhibited the examined samples were arranged in two main clusters in accordance with their group. Projection to Latent Structures Discriminant Anal. (PLS-DA) revealed there was a noticeable separation between neurobrucellosis and normal groups. Orthogonal Partial Least-Squares-Discriminant Anal. (OPLS-DA) could responsibly illuminate the differences between neurobrucellosis and normal controls. Neurobrucellosis showed a total of 155 differentiated metabolites. Prominent potential biomarkers including 30 metabolites were then selected out, regarded as more capable of distinguishing neurobrucellosis. TNF-α and IL-6 in CSF were remarkably increased in neurobrucellosis. We presented the heatmaps and correlation analyses among the identified 30 potential biomarkers. In conclusion, this study showed that CSF metabolomics based on LC-MS could distinguish neurobrucellosis patients from normal controls. Our data offered perspectives for diagnosis and treatment for neurobrucellosis.

Cui, Lei published the artcilePhase identification using modified principal component analysis for industrial 2-keto-L-gulonic acid fermentation, Formula: C6H10O7, the publication is Jisuanji Yu Yingyong Huaxue (2017), 34(9), 693-696, database is CAplus.

In this paper, based on the dynamic characteristics of industrial 2-keto-L-gulonic acid fermentation, the principal component anal. (PCA) with time delay window is proposed to identify the different stages of fermentation process. Only the online measurement data of the current batch, which related to the state of the fermentation process, are needed in the method. In order to obtain the dynamic relationship of the fermentation process, the time delay window is introduced, and the dynamic state of the t moment is represented by the process variables during the period from t-D to t, not just the moment t. The PC Scores of the PCA is used to obtain the curve of Hotelling′s T² statistical variable. The singular points of the curve contain more information of dynamic behavior, and could be used to detect different fermentation stages. Furthermore, it has significance to improve the level of process control, for example, it could offer real-time guidance for off-line sampling and anal. time.

Lu, Xiaolei published the artcileStudy on the hydration product of ettringite in cement paste with ethanol-diisopropanolamine, SDS of cas: 122-20-3, the publication is Journal of Thermal Analysis and Calorimetry (2020), 139(2), 1007-1016, database is CAplus.

A review. Ettringite (AFt) is a very important hydration product of hardened cement pastes in the early stage. The effect of ethanol-diisopropanolamine (EDIPA) on the formation and transform process of AFt in cement pastes was systematically investigated in this paper. The results indicate that the AFt content in hardened cement pastes notably decreases due to the inhibition effect of EDIPA on the dissolution of gypsum. In addition, EDIPA promotes the transformation of AFt into calcium monosulfoaluminate hydrate and considerably alters the morphol. of AFt crystals from the acicular crystals to stubby rods crystals. The mechanism of the formation of EDIPA-Ca²⁺ complex by the interaction between Ca²⁺ in ettringite and the oxygen atoms in EDIPA mol. was proposed. EDIPA-Ca²⁺ complex can slow down or prevent the crystal growth process of AFt and lead to altering the morphol. of AFt crystals.
