And the article contained the following:

We report a novel solid-state mol. device structure based on double self-assembled monolayers (D-SAM) incorporated into the suspended nanowire architecture to form a “Au|SAM-1||SAM-2|Au” junction. Using com. available thiol mols. that are devoid of synthetic difficulty, we constructed a “Au|S-(CH2)6-ferrocene||SAM-2|Au” junction with various lengths and chem. structures of SAM-2 to tune the coupling between the ferrocene conductive MO and electrode of the junction. Combining low noise and a wide temperature range measurement, we demonstrated systematically modulated conduction depending on the length and chem. nature of SAM-2. Meanwhile, the transport mechanism transition from tunneling to hopping and the intermediate state accompanied by the current fluctuation due to the coexistence of the hopping and tunneling transport channels were observed Considering the versatility of this solid-state D-SAM in modulating the electrode-mol. interface and electroactive groups, this strategy thus provides a novel facile strategy for tailorable nanoscale charge transport studies and functional mol. devices. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Name: 1-Decanethiol

On September 30, 2022, Zhang, Qiaoli; Deng, Liying; Li, Mengchao; Wang, Xiaofeng; Li, Rui; Liu, Zheyuan; Yang, Chengkai; Wang, Xinghui; Liu, Wen; Yu, Yan published an article.Quality Control of SweetPearlR P300 DC Maltitol The title of the article was Regulation of Zinc Interface by Maltitol for Long-Life Dendrite-free Aqueous Zinc Ion Batteries. And the article contained the following:

The formation of dendrites and low coulombic efficiency hinder the application of aqueous zinc ion batteries in large energy storage systems. As the electrolyte additive, maltitol is adsorbed on the zinc to regulate the anode interface. The maltitol inhibits the growth of zinc dendrites and improves the cycling stability of the zinc anode, which has been proven by a series of electrochem. approaches. The scanning electron microscope and the in situ optical microscope have recorded the smooth deposition of the zinc. The mechanism of interface regulation has been implemented by specific adsorption and deceleration kinetics, verified by XPS, Raman spectra, and DFT calculations The Zn//Zn sym. cells reached a stable plating/stripping performance over 1000 h at 2 mA cm-2 with 2 mA h cm-2. This cheap and eco-friendly additive provides an alternative for the application of aqueous zinc ion batteries. The experimental process involved the reaction of SweetPearlR P300 DC Maltitol(cas: 585-88-6).Quality Control of SweetPearlR P300 DC Maltitol

On April 30, 2020, Vol’eva, V. B.; Zhorin, V. A.; Ovsyannikova, M. N.; Kurkovskaya, L. N. published an article.Computed Properties of 96-76-4 The title of the article was Solid-Phase ortho-Hydroxylation of 2,4-Di-tert-butylphenol and Its Derivatives. And the article contained the following:

Direct phenol-catechol conversion was realized as a result of the solid-phase reaction of 2,4-di-tert-butylphenol with cuprous oxide under high pressure and shear deformation on the Bridgman anvils. The yield of 3,5-di-tert-butylcatechol in this reaction was about 85%. When cupric oxide was used in the solid-phase process, oxidative coupling of the starting phenol took place, resulting in quant. formation of tetra-tert-butyl-ortho-bisphenol. The reaction of 6-substituted derivatives of 2,4-di-tert-butylphenol with cuprous oxide was used as an example to demonstrate the possibility of substitutive ortho-hydroxylation yielding 7-20% of pyrocatechols. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Computed Properties of 96-76-4

On December 31, 2021, Bhanderi, Khushboo; Ghalsasi, Prasanna S.; Inoue, Katsuya published an article.Computed Properties of 96-76-4 The title of the article was Nonconventional driving force for selective oxidative C-C coupling reaction due to concurrent and curious formation of Ag0. And the article contained the following:

Herein, reduction of [Ag(NH3)2]+ to Ag0 with concurrent oxidation of different phenols/naphthols to biphenyls was undertaken. The work was originated during careful observation of an undergraduate experiment-Tollen’s test-where silver mirror film deposition takes place on the walls of borosilicate glass test tube. When the same reaction was carried out in polypropylene (plastic-Eppendorf) tube, aggregation of Ag0 leading to floating Ag-particles was observed but not silver film deposition. This prompted to carry out challenging cross-coupling reaction by only changing the surface of the reaction flask from glass to plastic to silicones. Surprisingly, good selective oxidative homo-coupling on Teflon surface while cross-coupling in Eppendorf vial was observed Thus, the formation of biphenyl is driven by the macroscopic growth of Ag0 into [Ag-particle] orchestrated by Ag…Ag cohesive interaction was proposed. To validate results, experiments were also performed on gram scale. More importantly, oxidation of β-naphthol carried out in quartz (chiral) tube which yielded slight enantioselective excess of BINOL. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Computed Properties of 96-76-4
