Category: alcohols-buliding-blocks《Effect of Position and Structure of the Terminal Moieties in the Side Group on the Liquid Crystal Alignment Behavior of Polystyrene Derivatives》 was published in 2021. The authors were Yang, DaEun;Seo, Kyutae;Kang, Hyo, and the article was included in《Polymers (Basel, Switzerland)》. The author mentioned the following in the article:

We synthesized a series of polystyrene derivatives containing various side groups, such as the 4-(tert-butyl)-phenoxymethyl, 3-(tert-butyl)-phenoxymethyl, 2-(tert-butyl)-phenoxymethyl, 4-cumyl-phenoxymethyl, and 4-trityl-phenoxymethyl groups, through a polymer modification reaction to examine the liquid crystal (LC) alignment of these derivatives In general, the vertical LC alignment on polymer films can be affected by the position and structure of the terminal moiety of the polymer side group. For example, the LC cells fabricated with 4-(tert-butyl)-phenoxymethyl-substituted polystyrene having a tert-Bu moiety as a para-type attachment to the phenoxy groups of the polystyrene derivatives exhibited vertical LC alignment, whereas the LC cells prepared from 3-(tert-butyl)- and 2-(tert-butyl)-phenoxymethyl-substituted polystyrene films exhibited planar LC alignment. In addition, the LC cells fabricated from 4-cumyl- and 4-trityl-phenoxymethyl-substituted polystyrene films with addnl. Ph rings in the side groups exhibited planar LC alignment, in contrast to the LC alignment of the (tert-butyl)-phenoxymethyl-substituted polystyrene series. The vertical LC orientation was well correlated with the surface energy of these polymer films. For example, vertical LC orientation, which mainly originates due to the nonpolar tertiary carbon moiety having bulky groups, was observed when the surface energy of the polymer was lower than 36.6 mJ/m². To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

Zhang, Leijiang;Wang, Bianna;Ma, Wenjie;Li, Bing;Liu, Yonglei;Du, Yunchen published 《Fe₃C/Fe nanoparticles decorated three-dimensional nitrogen-doped carbon foams for highly efficient bisphenol A removal through peroxymonosulfate activation》. The research results were published in《Chemical Engineering Journal (Amsterdam, Netherlands)》 in 2022.Name: 4-(2-Phenylpropan-2-yl)phenol The article conveys some information:

The design of heterogeneous catalysts has become one of the most important steps in the popularization of advanced oxidation processes for wastewater remediation. With a nitrate-assisted polymer-bubbling strategy, we prepared three-dimensional carbon foams decorated by commensal Fe₃C/Fe nanoparticles through a direct pyrolysis of the mixture of polyvinyl pyrrolidone and ferric nitrate nonahydrate. The as-obtained composites, Fe₃C/Fe@NCFs, are employed as heterogeneous peroxymonosulfate (PMS) activators to remove bisphenol A (BPA) in aquatic environments with a predetermined concentration It is found that both Fe₃C/Fe nanoparticles and N-doped carbon frameworks can activate PMS to release powerful oxidative species for BPA removal. The effect of pyrolysis temperature on the catalytic performance of Fe₃C/Fe@NCFs is studied in detail. The results reveal that high pyrolysis temperature induces the agglomeration of Fe₃C/Fe nanoparticles and the loss of N content, and low pyrolysis temperature only generates low-crystallinity carbon frameworks and small proportion of graphitic N configuration. Therefore, Fe₃C/Fe@NCFs from moderate temperature (700 °C) can produce the highest BPA removal efficiency. The synergy of Fe₃C/Fe nanoparticles and N-doped carbon frameworks, as well as the structure advantages is clearly established in comparison with some control samples. Quenching experiments and ESR (EPR) tests indicate that BPA can be degraded in both radical pathway and non-radical pathway, where SO·^–₄, ·O^–₂, and ¹O₂ are primary reactive species. In addition, the influences of some routine factors and actual water backgrounds were also investigated and analyzed comprehensively. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

Computed Properties of C15H16OIn 2022, Sun, Ruiting;Lu, Fuwei;Yu, Chunmei;Yang, Yanan;Qiao, Lizhen;Liu, Anmin published 《Peanut shells-derived biochars as adsorbents for the pipette-tip solid-phase extraction of endocrine-disrupting phenols in water, milk and beverage》. 《Journal of Chromatography A》published the findings. The article contains the following contents:

In the present work, a type of biochar materials derived from carbonizing peanut shells were obtained and employed as the adsorbents of pipet-tip solid-phase extraction (PT-SPE) for the enrichment and determination of six endocrine-disrupting phenols (EDPs) in combination with high-performance liquid chromatog. equipped with UV detector (HPLC-UV). Abundant aliphatic and aromatic carbon structures and functional groups from polar heteroatoms (N, O, S) were distributed in the low-cost and eco-friendly peanut shells-derived biochar materials and were favorable for the enrichment of target EDPs. Moreover, the theor. calculation based on d. functional theory (DFT) proved that the effective enrichment of EDPs in aqueous samples benefited from the effective adsorption on the peanut shells-derived biochar materials. The exptl. factors influencing the extraction efficiency were investigated, including adsorbent amount, aspirating/dispensing cycles, the type of elution solvent and elution times, salt addition, sample solution pH and type and volume of washing solvent. Under the optimal conditions, the proposed PT-SPE method exhibited good linear relationship (R2 > 0.993) in the range of 0.5-400μg/L and low limits of detections (LODs) from 0.25 to 2.5μg/L, as well as good precision and accuracy with relative standard deviations (RSDs) of 0.3%-13.2% and recoveries of 83.5%-117.1%. Finally, the biochars-based miniaturized pretreatment method was employed for the determination of six EDPs in bottled water, milk, tea beverage and disposal plastic bag soaked solution with recoveries from 77.5% to 116.5%. The experimental procedure involved many compounds, such as 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

HPLC of Formula: 599-64-4In 2020, Medvedev, Alexander V.;Medvedeva, Lyubov A.;Martsen, Elena;Moeser, Mathew;Gorman, Kristen L.;Lin, Benjamin;Blackwell, Brett;Villeneuve, Daniel L.;Houck, Keith A.;Crofton, Kevin M.;Makarov, Sergei S. published 《Harmonized Cross-Species Assessment of Endocrine and Metabolic Disruptors by Ecotox FACTORIAL Assay》. 《Environmental Science & Technology》published the findings. The article contains the following contents:

Environmental pollution is a threat to humans and wildlife species. Of particular concern are endocrine disrupting chems. (EDCs). An important target of EDCs is nuclear receptors (NRs) that control endocrine and metabolic responses through transcriptional regulation. Owing in part to structural differences of NRs, adverse effects of EDCs vary significantly among species. Here, we describe a multiplexed reporter assay (the Ecotox FACTORIAL) enabling parallel assessment of compounds’ effects on estrogen, androgen, thyroid, and PPARγ receptors of representative mammals, birds, reptiles, amphibians, and fish. The Ecotox FACTORIAL is a single-well assay comprising a set of species-specific, one-hybrid GAL4-NR reporter constructs transiently transfected into test cells. To harmonize cross-species assessments, we used a combination of two approaches. First, we used the same type of test cells for all reporters; second, we implemented a parallel detection of reporter RNAs. The assay demonstrated excellent quality, reproducibility, and insignificant intra-assay variability. Importantly, the EC₅₀ values for NR ligands were consistent with those reported for conventional assays. Using the assay allowed ranking the hazard potential of environmental pollutants (e.g., bisphenols, polycyclic aromatic hydrocarbons, and synthetic progestins) across species. Furthermore, the assay permitted detecting taxa-specific effects of surface water samples. Therefore, the Ecotox FACTORIAL enables harmonized assessment of the endocrine and metabolic disrupting activity of chems. and surface water in humans as well as in wildlife species. And 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) was used in the research process.

Children in low- and middle-income countries are often exposed to higher levels of chems. and are more vulnerable to the health effects of air pollution. Little is known about the diversity, toxicity, and dynamics of airborne chem. exposures at the mol. level. We developed a workflow employing state-of-the-art wearable passive sampling technol. coupled with high-resolution mass spectrometry to comprehensively measure 147 children’s personal exposures to airborne chems. in Limpopo, South Africa, as part of the Venda Health Examination of Mothers, Babies, and Their Environment (VHEMBE). 637 environmental exposures were detected, many of which have never been measured in this population; of these 50 airborne chem. exposures of concern were detected, including pesticides, plasticizers, organophosphates, dyes, combustion products, and perfumes. Biocides detected in wristbands included p,p’-dichlorodiphenyltrichloroethane (p,p’-DDT), p,p’-dichlorodiphenyldichloroethane (p,p’-DDD), p,p’-dichlorodiphenyldichloroethylene (p,p’-DDE), propoxur, piperonyl butoxide, and triclosan. Exposures differed across the assessment period with 27% of detected chems. observed to be either higher or lower in the wet or dry seasons. And 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) was used in the research process.

HPLC of Formula: 599-64-4《Removal of selected emerging micropollutants from wastewater treatment plant effluent by advanced non-oxidative treatment – A lab-scale case study from Serbia》 was published in 2021. The authors were Bogunovic, Minja;Ivancev-Tumbas, Ivana;Cesen, Marjeta;Sekulic, Tatjana Djakovic;Prodanovic, Jelena;Tubic, Aleksandra;Heath, David;Heath, Ester, and the article was included in《Science of the Total Environment》. The author mentioned the following in the article:

The presence of 48 emerging micropollutants was tested in influent and effluent from primary and secondary treatment at a municipal wastewater treatment plant (WWTP) in Serbia. Sixteen emerging micropollutants (active pharmaceutical ingredients, bisphenols, parabens and UV filters) had concentrations >LOQ (maximum concentrate 33.4μg/L). The removal efficiency of primary treatment ranged from 2.0% – 96.0%. In the case of secondary treatment, except for ketoprofen (61.0%), diclofenac (62.6%) and carbamazepine (-20.0%), all other measured micropollutants had removal efficiency above 77.0%. Advanced non-oxidative lab-scale treatments were investigated. Powd. activated carbon (PAC) adsorption achieved removal efficiencies in the range 52.4-99.9%, novel coagulation with natural coagulant isolated from beans achieved removal efficiencies in range 3.2-99.9%, conventional coagulation with ferric chloride 3.12-96.4%, combined adsorption/coagulation 2.69-99.9% and combined PAC/ultrafiltration (PAC/UF) 60-99.9%. For most of the micropollutants, their removal efficiencies were similar to that reported in the literature. Novel natural coagulant showed significant potential compared to the conventional coagulant during a short episode of sub-optimal WWTP operation. When natural coagulant was applied as a part of an adsorption/coagulation hybrid process, there was no neg. effect on PAC adsorption, while for conventional coagulant that was not always the case. Also, a structure property relationship (SPR) study revealed correlations between the removal efficiency of the majority of treatments applied and total polar surface area (TPSA) of the micropollutants. And 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) was used in the research process.

The research results were published in《Dental Materials》 in 2021.Synthetic Route of C15H16O The article conveys some information:

To evaluate high refractive index methacrylates as diluents for the formulation of radiopaque esthetic bulk-fill composites.2-(4-Cumylphenoxy)ethyl methacrylate 1, 2-(2-phenylphenoxy)ethyl methacrylate 2 and 2-[2-(2-phenylphenoxy)ethoxy]ethyl methacrylate 3 were synthesized and characterized by ¹H NMR spectroscopy. The reactivity of each monomer was studied using photo-DSC. Bulk-fill composites based on monomers 1-3 were formulated. Translucency (before and after light cure) was measured using a spectrophotometer. The depth of cure and the water sorption of these materials were determined according to ISO 4049. The flexural strength and modulus of elasticity were measured using a three-point bending setup, according to ISO 4049. The shrinkage force was assessed based on a method described by Watts et al. using a universal testing machine.Monomers 1-3 were easily synthesized in two steps. They exhibit a low viscosity and a high refractive index (1.553-1.573). Monofunctional methacrylates 1-3 were found to be more reactive than triethylene glycol dimethacrylate (TEGDMA). Bulk-fill composites based on these monomers were successfully prepared They exhibit a high depth of cure and excellent esthetic properties (low transparency). These composites provide higher flexural modulus as well as lower water sorption than a corresponding material based on TEGDMA. Methacrylates 1 and 3 are particularly interesting as they led to composites showing lower shrinkage force.Methacrylates 1-3 are promising diluents for the formulation of highly esthetic radiopaque bulk-fill composites. To complete the study, the researchers used 4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) .

Herein, a rhodium-catalyzed amination of phenols, which provided concise access to diverse anilines, with water as the sole byproduct was described. The arenophilic rhodium catalyst facilitated the inherently difficult keto-enol tautomerization of phenols by means of π-coordination, allowing for the subsequent dehydrative condensation with amines. The generality of this redox-neutral catalysis by carrying out reactions of a large array of phenols with various electronic properties and a wide variety of primary and secondary amines was demonstrated. Several examples of late-stage functionalization of structurally complex bioactive mols., including pharmaceuticals, further illustrated the potential broad utility of the method.4-(2-Phenylpropan-2-yl)phenol (cas: 599-64-4) were involved in the experimental procedure.
