And the article was included in Acta Biomaterialia in 2022.Name: 2,2′-Oxybis(ethan-1-ol) This article mentions the following:

Flexible, self-healing and adhesive conductive materials with Young′s modulus matching biol. tissues are highly desired for applications in bioelectronics. Here, we report self-healing, stretchable, highly adhesive and conductive hydrogels obtained by mixing polyvinyl alc., sodium tetraborate and a screen printing paste containing the conducting polymer Poly (3,4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) and diol additives. The as prepared hydrogels exhibited modeling ability, high adhesion on pig skin (1.96 N/cm²), high plastic stretchability (>10000%), a moderate conductivity, a low compressive modulus (0.3-3.7 KPa), a good strain sensitivity (gauge factor = 3.88 at 500% strain), and remarkable self-healing properties. Epidermal patch electrodes prepared using one of our hydrogels demonstrated high-quality recording of electrocardiog. (ECG) and electromyog. (EMG) signal. Because of their straightforward fabrication, outstanding mech. properties and possibility to combine the electrode components in a single material, hydrogels based on PVA, borax and PEDOT:PSS are highly promising for applications in bioelectronics and wearable electronics. Soft materials with elec. conductivity are investigated for healthcare applications, such as electrodes to measure vital signs that can easily adapt to the shape and the movements of human skin. Conductive hydrogels (i.e. gels containing water) are ideal materials for this purpose due softness and flexibility. In this this work, we report hydrogels obtained mixing an elec. conductive polymer, a water-soluble biocompatible polymer and a salt. These materials show high adhesion on skin, elec. conductivity and ability to self-repair after a mech. damage. These hydrogels were successfully used to fabricate electrode to measure cardiac and muscular elec. signals. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Name: 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. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Name: 2,2′-Oxybis(ethan-1-ol)

Synthesis of cobalt single atom catalyst by a solid-state transformation strategy for direct C-C cross-coupling of primary and secondary alcohols was written by Li, Zhijun;Chen, Yuying;Lu, Xiaowen;Li, Honghong;Leng, Leipeng;Zhang, Tinglei;Horton, J. Hugh. And the article was included in Nano Research in 2022.Name: (4-Chlorophenyl)methanol This article mentions the following:

Atomic engineering of single atom catalysts (SACs) with high-d. available active sites and optimized electronic properties can substantially boost catalytic efficacy. Herein, we report a solid-state transformation strategy to access Co SACs by introducing Co species from com. Co₂O₃ powders into nitrogen-doped carbon support. The catalyst exhibited excellent catalytic activity, with a turnover frequency (TOF) of 2,307 h^-1 and yield of 95%, in the direct C-C cross-coupling of benzyl alc. and 1-phenylethanol (1 atm O₂@80 °C) to yield chalcone. D. functional theory (DFT) calculations demonstrate the coordination environment and electronic metal-support interaction impact the catalytic pathway. In particular, a wide substrate scope and a broad functional-group tolerance of this SAC were validated, and the employment of this strategy for large-scale synthesis was also shown to be feasible. This work might shed light on the facile and scalable synthesis of highly active, selective, and stable SACs for heterogeneous catalysis. In the experiment, the researchers used many compounds, for example, (4-Chlorophenyl)methanol (cas: 873-76-7Name: (4-Chlorophenyl)methanol).

(4-Chlorophenyl)methanol (cas: 873-76-7) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Name: (4-Chlorophenyl)methanol

Comprehensive chocolate aroma characterization in beverages containing jackfruit seed flours and cocoa powder was written by Spada, Fernanda Papa;de Alencar, Severino Matias;Purgatto, Eduardo. And the article was included in Future Foods in 2022.Reference of 3391-86-4 This article mentions the following:

Jackfruit (Artocarpus heterophyllus Lam) occurs abundantly in Brazil, but its seeds are often underutilized in food nutrition. Previously, we showed that roasted jackfruit seeds are an innovative source of chocolate aroma. In this study, we characterized the volatile content of exptl. beverages containing jackfruit seed flours as compared to non-alk. cocoa powder. The three key results of this study were that (i) the fermented jackfruit seed flour beverage (FJSBev) was similar to the non-alk. cocoa powder beverage (CTRLBev); (ii) similar volatile groups (acids, alcs., aldehydes, ester, furans, and pyrazines) were identified in the samples (FJSBev and CTRLBev); (iii) the beverages contained volatile compounds with a low threshold of cocoa attributes (butter, cocoa, coffee, floral, fruit, green, honey, mushroom, nut, and roasted). To conclude, the beverage formulation containing fermented jackfruit seeds had more volatile compounds and odor-active constituents than that with non-alk. cocoa powder. Collectively, our data demonstrate that fermentation is critical to producing a chocolate aroma. Fermented jackfruit seed flours could be used as a partial or total additive to improve chocolate aroma in food formulations. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Reference of 3391-86-4).

Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Reference of 3391-86-4

Orange peel fermentation using Lactiplantibacillus plantarum: microbiological analysis and physico-chemical characterisation was written by Deba-Rementeria, Shuyana;Estrada, Olaia;Issa-Issa, Hanan;Vazquez-Araujo, Laura. And the article was included in International Journal of Food Science and Technology in 2022.Related Products of 149-32-6 This article mentions the following:

Summary : To find an innovative use for orange peels discarded in the orange juice-making process, a fermentative process was assessed using a Lactiplantibacillus plantarum strain. Blanched or rinsed peels were submerged in a 5% NaCl-3% inoculated sucrose brine for 10 days. Total soluble solids, pH, sugars and total aerobic and anaerobic counts were determined in the brines to characterize the process. The final products were characterised by instrumental texture, color and volatile composition The blanching pretreatment had a significant effect on the whole process and the final product characteristics. Anaerobic bacteria total counts were significantly higher in the blanched samples during the whole fermentation, and pH decreased significantly slower in these samples than in the rinsed ones. Rinsed samples were characterised by higher aerobic total counts, higher sucrose consumption and higher glucose, fructose and polyalcs. production The texture was softer in the pretreated samples, probably due to the blanching process rather than the fermentation The volatile composition was quite similar between samples, although it was different from one of the raw orange peels due to a significant decrease in various volatile compounds In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Related Products of 149-32-6).

(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) 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. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Related Products of 149-32-6

Applicability of pea ingredients in baked products: Links between formulation, reactivity potential and physicochemical properties was written by Krause, Svenja;Asamoah, Eugenia Ayebea;Huc-Mathis, Delphine;Moulin, Gabrielle;Jakobi, Ralf;Rega, Barbara;Bonazzi, Catherine. And the article was included in Food Chemistry in 2022.Recommanded Product: 3391-86-4 This article mentions the following:

This study aimed to evaluate the applicability of purified pea ingredients (starch and protein isolate) by assessing their potential to form volatile compounds during the different steps of sponge cake development compared to pea flour and wheat flour. While pea flour was highly susceptible to lipid oxidation during batter beating, the combination of purified pea starch and pea protein yielded significantly fewer oxidation markers with known green-beany off-odors. This was due more to the inactivation of lipoxygenase during flour fractionation than to differences in batter structure. However, fractionated ingredients were highly prone to participating in the Maillard reaction and caramelization during baking, leading to a more complex mixture of pyrazines, Strecker aldehydes and furanic compounds with potential malty and roasted notes compared to cakes based on pea flour or wheat flour. These findings confirm that using purified pea fractions can create high-quality products with an attractive composition In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Recommanded Product: 3391-86-4).

Oct-1-en-3-ol (cas: 3391-86-4) 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. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 3391-86-4

Self-Assembled Monolayers from Biphenyldithiol Derivatives: Optimization of the Deprotection Procedure and Effect of the Molecular Conformation was written by Shaporenko, Andrey;Elbing, Mark;Blaszczyk, Alfred;Von Haenisch, Carsten;Mayor, Marcel;Zharnikov, Michael. And the article was included in Journal of Physical Chemistry B in 2006.Application of 29364-29-2 This article mentions the following:

A series of biphenyl-derived dithiol (BDDT) compounds with terminal acetyl-protected sulfur groups and different structural arrangements of both Ph rings have been synthesized and fully characterized. The different arrangements were achieved by introducing hydrocarbon substituents in the 2 and 2′ positions of the biphenyl backbone. The presented model compounds enable the investigation of the correlation between the intramol. conformation and other phys. properties of interest, like, e.g., mol. assembly or electronic transport properties. Here, the ability of these model compounds to form self-assembled monolayers (SAMs) on Au(111) and Ag(111) is investigated in details. The deprotection of the target mols. was performed in situ using either NH₄OH or triethylamine (TEA) deprotection agent. The fabricated films were characterized by synchrotron-based high-resolution photoelectron spectroscopy and near-edge absorption fine structure spectroscopy. Whereas the deprotection by NH₄OH was found to result in the formation of multilayer films, the deprotection by TEA allowed the preparation of densely packed BDDT SAMs with a noticeably higher orientational order and smaller mol. inclination on Ag than on Au. Introduction of the alkyl bridge between the individual rings of the biphenyl backbone did not lead to a noticeable change in the structure and packing d. of the BDDT SAMs as long as the mol. had a planar conformation in the resp. SAM. The deviation from this conformation resulted in the deterioration of the film quality and a decrease of the orientational order. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Application of 29364-29-2).

Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 29364-29-2

A streamlined synthesis of extended thiophloroglucinol ligands and their trinuclear Ni^II₃ complexes was written by Feldscher, Bastian;Theil, Hubert;Stammler, Anja;Boegge, Hartmut;Glaser, Thorsten. And the article was included in Dalton Transactions in 2014.Name: Sodium 2-methyl-2-propanethiolate This article mentions the following:

A protocol for the synthesis of trinucleating C₃-sym. ligands based on a central meta-phenylene bridging 1,3,5-trimercaptobenzene (thiophloroglucinol) backbone was established. The key compound turned out to be the trialdehyde obtained from the triple nucleophilic attack of dimethyldithiocarbamate at 1,3,5-tribromo-2,4,6-triformylbenzene. Reacting this trialdehyde with six equivalent of a primary amine results in the simultaneous dithiocarbamate cleavage and Schiff-base formation providing the extended thiophloroglucinol ligands H₃bertdien, H₆bert^Me, H₆bert^t-Bu₂, and H₆habbi. Reaction with Ni^II gives the trinuclear Ni^II₃ complexes [(bertdien)Ni^II₃](X)₃ (X = BPh₄^–, BF₄^–), [(bert^Me)Ni^II₃], [(bert^t-Bu₂)Ni^II₃], and [(habbi)Ni^II₃], which were characterized spectroscopically, electrochem., and crystallog. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Name: Sodium 2-methyl-2-propanethiolate).

Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols.
