Effect of polar groups of polystyrenes on the self-assembly of breath figure arrays was written by Zhou, Di;Wu, Bai-Heng;Yang, Wen-Wu;Li, Xiao;Zhu, Liang-Wei;Xu, Zhi-Kang;Wan, Ling-Shu. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2022.Recommanded Product: 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

The breath figure (BF) process has been widely used to prepare patterned porous films. The mechanism remains to be further elucidated, especially how polymer architectures affect the stability of water droplets and the pore structure. Polystyrenes (PS) was functionalized with a series of polar groups both in chain middle and chain end, which was synthesized by using difunctional atom transfer radical polymerization (ATRP) initiators with the combination of nucleophilic substitution of the end bromine. It is found that PS with polar groups, which help to reduce interfacial tension, tends to form regular patterns at low concentration and to generate multilayered pores. The coalescence resistance measurement was performed to characterize the stabilization of water droplets from polymers by precipitation The results show opposite trend with the results of the BF process, indicating a minor role played by polymer precipitation on microdroplets stabilization. We reveal that addition of only an oxyethyl group in the chain middle of PS contributes to the formation of ordered patterns. This study helps to shed light on the impact of polymer architectures on the self-assembly behavior in the BF process. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Recommanded Product: 2,2′-Oxybis(ethan-1-ol)).

Antibacterial properties of laser-encapsulated titanium oxide nanotubes decorated with nanosilver and covered with chitosan/Eudragit polymers was written by Pawlowski, Lukasz;Wawrzyniak, Jakub;Banach-Kopec, Adrianna;Cieslik, Bartlomiej Michal;Jurak, Kacper;Karczewski, Jakub;Tylingo, Robert;Siuzdak, Katarzyna;Zielinski, Andrzej. And the article was included in Biomaterials Advances in 2022.Recommanded Product: 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

To provide antibacterial properties, the titanium samples were subjected to electrochem. oxidation in the fluoride-containing diethylene glycol-based electrolyte to create a titanium oxide nanotubular surface. Afterward, the surface was covered by sputtering with silver 5 nm film, and the tops of the nanotubes were capped using laser treatment, resulting in an appearance of silver nanoparticles (AgNPs) of around 30 nm in diameter on such a modified surface. To ensure a controlled release of the bactericidal substance, the samples were addnl. coated with a pH-sensitive chitosan/Eudragit 100 coating, also exhibiting bactericidal properties. The modified titanium samples were characterized using SEM, EDS, AFM, Raman, and XPS techniques. The wettability, corrosion properties, adhesion of the coating to the substrate, the release of AgNPs into solutions simulating body fluids at different pH, and antibacterial properties were further investigated. The obtained composite coatings were hydrophilic, adjacent to the surface, and corrosion-resistant. An increase in the amount of silver released as ions or metallic particles into a simulated body fluid solution at acidic pH was observed for modified samples with the biopolymer coating after three days of exposure avoiding burst effect. The proposed modification was effective against both Gram-pos. and Gram-neg. bacteria. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Recommanded Product: 2,2′-Oxybis(ethan-1-ol)).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers.

Piezo-photoelectric all-in-one coaxial hierarchical TiO₂-BaTiO₃-CuInS₂ heterostructure for synergistic water splitting was written by Yang, M.;Wang, Y.;Ma, H.;Chen, L.;Ge, S.;Wang, X.;Yu, J.;Cheng, Z.. And the article was included in Materials Today Chemistry in 2022.Application of 111-46-6 This article mentions the following:

Rational multiple-field coupling, component control, and microarchitectures design for utilization of multiform driving forces as well as benefiting charge-carrier separation and migration is considered to be an outstanding approach to improve water splitting efficiency for alleviating increasing environmental problems. Herein, a novel piezo-photoelec. catalyst, coaxial TiO₂-BaTiO₃-CuInS₂ heterostructures, was designed for efficient hydrogen production, synergistically driven by mech. force, electricity, and light. The vertical growth of TiO₂ nanorods guarantees sufficient generation of photoinduced charges and their fast migration. Elec. field generated by the piezoelec. BaTiO₃ shell under a mech. driving force will promote the separation and transfer of photogenerated charge carriers, thereby minimizing the probability of charge recombination. The further incorporation of the outermost layer of CuInS₂ is beneficial to broaden light harvesting. Of particular importance is the cascade band arrangement of the three different functional components, which greatly enhances the transfer of photo- and piezoelec. induced charges. With the synergy of enhanced light harvesting, energy band engineering, and nanostructure interfacial design, the fabricated TiO₂-BaTiO₃-CuInS₂ photoelectrode has achieved significant enhancement of piezo-photoelec. hydrogen evolution efficiency and could be expanded for pollutant decomposition This simple yet general strategy provides valuable guidance for cooperatively capitalizing on piezoelectricity to engineer high-performing energy conversion and environmental protection. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Application of 111-46-6).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Application of 111-46-6

Enhanced ready biodegradability screening tests for the evaluation of potential PBT substances was written by Gartiser, Stefan;Brunswik-Titze, Andrea;Flach, Felicitas;Junker, Thomas;Saettler, Daniel;Joehncke, Ulrich. And the article was included in Science of the Total Environment in 2022.Application In Synthesis of 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

In persistence assessment enhanced ready biodegradation tests (eRBT) are aimed to close the gap between screening tests and complex simulation tests. However, only few data from these tests are available and neither guidance on the design and interpretation of eRBTs, nor suitable validity criteria have been established so far. In a practical testing program 5 compounds with controversial degradation data have been tested in 4 test series including prolongation to 60 days and use of different inocula (activated sludge, final effluent from a STP), flask sizes, and endpoints (CO₂, O₂, DOC). The drug ibuprofen and the intermediate 4-fluorophenol were biodegraded by >60% within 28 days within a 10-day-window and therefore are considered as readily biodegradable and in conclusion fulfilling the criteria for “not persistent”. The mean mineralization of the pesticide synergist piperonylbutoxide and the antioxidant octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate achieved 20%-50% (=”potentially P”). The mineralization of the cosmetic ingredient cis-13-docosenonamide (Erucamide) was between 36%-64% after 60 days with activated sludge and 21% with the effluent from the STP. Diethylene glycol reached the pass level of 60% mineralization within 28 days in all test series without always meeting the 10-day window, and thus proved to be a suitable reference substance for eRBTs. Based on the results of the study several recommendations for the test design, the evaluation and the interpretation of eRBTs are made. However, a broader data set is required and further enhancements such as the quality and amount of the inoculum should also be considered in future research. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Application In Synthesis of 2,2′-Oxybis(ethan-1-ol)).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application In Synthesis of 2,2′-Oxybis(ethan-1-ol)

Identification of chemicals leaching from dental resin-based materials after in vitro chemical and salivary degradation was written by Vervliet, Philippe;De Nys, Siemon;Duca, Radu Corneliu;Boonen, Imke;Godderis, Lode;Elskens, Marc;Van Landuyt, Kirsten L.;Covaci, Adrian. And the article was included in Dental Materials in 2022.Application In Synthesis of 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

Only little is known about degradation of methacrylate monomers. Therefore, using in vitro chem. and saliva degradation this study aimed to identify the degradation products of organic compounds present in resin-based dental materials. Ten dental monomers and nine polymerized dental resin-based materials were immersed for 24 h in chem. media (0.1 M HCl, 0.1 M NaOH) and human pooled saliva in order to identify leached monomers and degradation products from chem. and saliva degradation Samples were analyzed using liquid chromatog. coupled to high-resolution mass spectrometry to identify previously unknown degradation products. During in vitro chem. degradation, uncured monomers were rapidly hydrolyzed into mono- and demethacrylated degradation products. During chem. degradation in alk. conditions of polymerized materials, considered the worst-case scenario, only degradation products could be detected. In acidic conditions, monomers and their degradation products were detected. In addition, different additives such as EDMAB, DMPA and HMBP were present in acidic degradation samples. Degradation in human pooled saliva for 24 h to mimic the in vivo situation, resulted in the identification of both monomers and their degradation products. Using state-of-the-art high-resolution mass spectrometry previously unknown degradation products of commonly used monomers were identified for the first time. Patients may be exposed to monomers and their degradation products in the first 24 h after restorative procedures. The results provide a base for further research on the degradation of resin-based dental composites in order to assess their safety using elution and toxicity studies.

Synthesis of bismaleate pentaerythritol ester and its application as PVC auxiliary heat stabilizer was written by Gao, Xinxin;Jiang, Pingping;Zhang, Zheming;Li, Zhenhua;Li, Yuchao;Leng, Yan;Zhang, Pingbo. And the article was included in Journal of Applied Polymer Science in 2022.Related Products of 111-46-6 This article mentions the following:

Diethylene glycol and maleic anhydride are used as raw materials to prepare bismaleic acid dibasic acid without catalyst. This intermediate product reacts with pentaerythritol (PER) to obtain bismaleate pentaerythritol (MDPP) as an auxiliary heat stabilizer. The structure of the product was verified by Fourier IR test and hydrogen nuclear magnetic spectrum anal. The ether bond, ester group, carbon-carbon double bond, polyol, and other characteristic structures contained in the mol. can improve thermal stability. Therefore, it can be used as an auxiliary heat stabilizer for PVC and used in combination with the main heat stabilizer. In order to verify the thermal stability performance and further analyze the thermal stability mechanism, testing methods such as thermal aging, Congo red, thermal weight loss, and elec. conductivity were adopted. The results show that when MDPP is added together with calcium/zinc stearate, the thermal stability of PVC is the best. The initial whiteness can reach 40 min, and the static stabilization time is 65 min, which is 15 min higher than the PVC sample with PER and calcium/zinc stearate. It can be seen that MDPP has greatly improved performance compared with the com. auxiliary heat stabilizer PER.

A Fully Biobased Aromatic Polyester Polyol for Polyisocyanurate Rigid Foams: Poly(diethylene furanoate) was written by Rhein, Michael;Demharter, Anton;Felker, Benjamin;Meier, Michael A. R.. And the article was included in ACS Applied Polymer Materials in 2022.Reference of 111-46-6 This article mentions the following:

Aromatic polyester polyols are often used in polyurethane rigid foam (PUR) and polyisocyanurate (PIR) synthesis, since they offer higher rigidity than polyether polyols. Herein, a route toward fully biobased aromatic polyester polyols was investigated using sugar-based 2,5-furandicarboxylic acid (FDCA) and diethylene glycol (DEG), enabling a direct one-step synthesis of a fully biobased aromatic polyester polyol, poly(diethylene furanoate) (PDEF), for applications in PIR rigid foam. Therefore, reaction conditions were optimized to obtain PDEF as a processable polyol with OH values and remaining unreacted DEG similar to a com., petroleum-based polyol. The processability was improved by either copolymerizing 10-20 mol % of a biobased aliphatic dicarboxylic acid, like succinic acid (SA) or adipic acid (AA), maintaining the fully biobased character of the polyol, or copolymerization with phthalic acid. The fully biobased polyester polyols were successfully prepared on a 100 g scale of dicarboxylic acids. Subsequent application in PIR rigid foam showed similar d., thermal conductivity, flame behavior, and compressive strength if compared to the rigid foam obtained from a com. polyol. Thus, fully biobased PDEF can substitute petroleum-based aromatic polyester polyols in PIR applications. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Reference of 111-46-6).

Polyurethanes are specialized polymeric materials with a diverse range of applications including foams, insulators, sealants, adhesives and elastomers. Anal. of these materials utilizing mass spectrometry is hampered by the polydispersity and the range of isomeric products produced during the polymerization process. To aid with the mass spectral studies of these materials we have developed methodologies to synthesize discreet polyether-based polyurethane oligomers that may be studied by mass spectrometry and used as standards in the anal. of more complex polymer products.

And the article was included in Microchemical Journal in 2022.Recommanded Product: 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

In this work, a new high-efficient salting-out agent, potassium tripolyphosphate, assisted liquid-liquid extraction (SALLE) sample preparation method for the determination of the polar ethylene glycol and diethylene glycol in liquid samples (food stimulants and liquid foods) were developed. To obtain satisfactory extraction efficiencies for the studied analytes, several parameters affecting the SALLE procedure were optimized. The effects of type of salting-out reagent, type of extraction solvent, volumes of ethanol, amount of potassium triphosphate, vortexing and standing times on the extraction efficiency were investigated. Anal. performances of the method were satisfactory, showed good linearity in the selected range (R²>0.9998), limits of detection (LOD) were 0.2 mg·L^-1 in all cases. Average recoveries in the ranges of 81.2-109.3% (RSD, 0.03-7.0%) for EG, 88.1 ∼ 109.1% (RSD, 0.1-8.6%) for DEG were obtained. In relation to the green and low solvent consumption, the proposed methodol. could be considered rapid and environment friendly. The developed method can be used not only for the determination of ethylene glycol and diethylene glycol in food simulation solution, but also for liquid foods with obtaining acceptable results.
