The article was appeared in 《Applied Clay Science》. They have made some progress in their research.Synthetic Route of C10H22O The article mentions the following:

The present work aimed to study the adsorption and desorption characteristics of Golden Flower Oil (GFO) on xerogel particles made of Clinoptilolite (CP), a natural zeolite and polyvinyl alc. (PVA). Firstly, chem. composition and phys. characteristics of GFO (by GC/MS) and CP (by SEM and BET) were thoroughly characterized. PVA/CP xerogel was synthesized then and characterized by SEM, BET, TGA, and DSC techniques. Adsorption of the 12 GFO components on the CP and PVA/CP xerogel surface was investigated in different concentrations of GFO components. Both adsorbents showed concentration-independent and selective adsorption for GFO components. The selective adsorption index showed a direct relationship with polarity (δP) of the components and inversely correlated with their molar volume (Vm). Adsorption isotherms of the components were fitted by Langmuir, Freundlich, and Temkin equations. Maximum monolayer GFO adsorption on PVA/CP surface was equal to 231.93 mg g-1 compared to 198.73 mg g-1 for CP as an adsorbent. The maximum desorbed amount for each of the components was directly related to the Vm parameter and the weight percentage of each GFO component in the oil and inversely related to δP. Multilayer desorbed amount from PVA/CP xerogel particles (366.03 mg g-1) was less than that for CP particles (573.36 mg g-1) supporting PVA/CP for retaining GFO for longer periods. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .

ACS Applied Energy Materials | Cas: 110-03-2 was involved in experiment

2,5-Dimethyl-2,5-hexanediol(cas:110-03-2) was used in the synthesis of six- and seven-membered heterocyclic boron compounds containing intramolecular N-B bond.Name: 2,5-Dimethyl-2,5-hexanediol

Zhou, Binghua;Zhou, Ying;Lai, Lujie;Chen, Ziling;Li, Jiajia;Jiang, Yunliang;Liu, Jian;Wang, Zhipeng;Xue, Zhigang published 《Fabrication of Borate-Based Porous Polymer Electrolytes Containing Cyclic Carbonate for High-Performance Lithium Metal Batteries》 in 2021. The article was appeared in 《ACS Applied Energy Materials》. They have made some progress in their research.Name: 2,5-Dimethyl-2,5-hexanediol The article mentions the following:

A series of borate-based porous polymer electrolytes (B-PPEs) is prepared by incorporating the copolymers containing cyclic boroxine and cyclic carbonate groups into poly(vinylidene fluoride) (PVDF) through the phase inversion method. The dense and well-interconnected pores are obtained in the polymer matrix when the content of the copolymer reached 40 wt %. The ethylene-oxygen chain segments in the copolymer can facilitate the mobility of polymer chains and form the uniform distribution of pores in the B-PPEs. The B-PPEs show an enhanced ionic conductivity of 1.32 x 10-3 S cm-1 at 30 °C, which is due to the uniform well-interconnected pores in the polymer host. The cyclic carbonate units interact with the liquid electrolyte, which could improve the electrolyte uptake capacity of the polymer matrix. Benefited from the Lewis acid-base interactions between boron moieties and the anions of the lithium salt, the lithium-ion transference number of B-PPEs is also significantly improved. Compared to the pure PVDF-based electrolyte, the Li/B-PPEs/Li cell displays a very stable polarization voltage and the long-time cycling for 1000 h at a c.d. of 0.2 mA cm-2. Moreover, the Li/B-PPEs/LiFePO4 cells deliver a higher capacity of 143.0 mAh g-1 at 0.2 C and 86% capacity retention after 150 cycles. The B-PPEs could be a promising candidate for enhancing the safety and electrochem. properties of lithium metal batteries.2,5-Dimethyl-2,5-hexanediol (cas: 110-03-2) were involved in the experimental procedure.

V. published 《Identification and Determination of the Components of Garden Sage (Salvia officinalis L.) Essential Oil, Isolated by Different Extraction Methods》. 《Journal of Analytical Chemistry》published the findings. The article contains the following contents:

We studied the component composition of the essential oil of garden sage (Salvia officinalis L.), obtained by various extraction methods. Essential oils were obtained by hydrodistillation and subcritical CO2 extraction, supercritical fluid extraction, and subcritical extraction with solid-phase and liquid-liquid preconcentration The components were identified by comparing the recorded mass spectra with the spectra of individual compounds and the data of the NIST07 and WILEY8 data bases. For all extraction methods, the major essential oil components were 1,8-cineole, camphor, α-thujone, β-thujone, borneol, 4-terpineol, β-caryophyllene, β-caryophyllene oxide, and viridiflorol. The concentration of analytes in the extracts varied depending on the extraction method. In total, 104 components were identified in the extracts, of which 30 were extracted by hydrodistillation, 32 by subcritical CO2 extraction, 14 by supercritical fluid extraction, 46 and 62 by subcritical extraction with solid-phase and liquid-liquid extraction into the organic phase. An increase in the number of components in more stringent extraction methods as compared to hydrodistillation showed that, in the extracts, a deeper decomposition of macrocomponents might take place, except for camphor. And 2-Hexyl-1-decanol (cas: 2425-77-6) was used in the research process.

Horie, Yoshifumi et al. published new progress in experiments with the help of cas: 140-66-9

4-tert-Octylphenol(cas: 140-66-9) is a common environmental pollutant showing weak estrogenic effects.Recommanded Product: 140-66-9 It has been shown to cause harm to vertebrate male reproductive systems.

Recommanded Product: 140-66-9《Gonadal Soma-Derived Factor Expression is a Potential Biomarker for Predicting the Effects of Endocrine-Disrupting Chemicals on Gonadal Differentiation in Japanese Medaka (Oryzias Latipes)》 was published in 2022. The authors were Horie, Yoshifumi;Kanazawa, Nobuhiro;Takahashi, Chiho;Tatarazako, Norihisa;Iguchi, Taisen, and the article was included in《Environmental Toxicology and Chemistry》. The author mentioned the following in the article:

Chems. with androgenic or estrogenic activity induce the sex reversal and/or intersex condition in various teleost fish species. Previously, we reported that exposure to 17α-methyltestosterone, bisphenol A, or 4-nonylphenol induces changes in expression of the gonadal soma-derived factor (gsdf) gene accompanied by disruption of gonadal differentiation in Japanese medaka (Oryzias latipes). These findings suggest that gsdf expression might be a useful biomarker for predicting the potential effect of chems. on gonadal differentiation. We examined the gsdf expression in Japanese medaka exposed to chems. with estrogenic or androgenic activity. Exposure to the androgenic steroid 17β-trenbolone at 0.5-22.1μg/L induced the development of ovotestis (presence of ovarian tissue with testicular tissue) and female-to-male sex reversal in XX embryos, and exposure at 6.32 and 22.1μg/L significantly increased gsdf expression in XX embryos compared with controls at developmental stage 38 (1 day before hatching). In the present study, no statistically significant difference in gsdf mRNA expression was observed after exposure to 17β-estradiol, 17α-ethinylestradiol, and 4-t-octylphenol, which have estrogenic activity. In addition, antiandrogenic chems. or chems. without endocrine-disrupting activity did not induce changes in gsdf expression in XX or XY embryos. Thus, an increase in gsdf expression after androgen exposure was observed in XX embryos. Together, these findings indicate that gsdf expression might be useful for predicting the adverse effect of chems. on gonadal differentiation.4-tert-Octylphenol (cas: 140-66-9) were involved in the experimental procedure.
