On January 31, 2020, Yong, Hansol; Park, Habin; Jung, Cheolsoo published an article.Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Quasi-solid-state gel polymer electrolyte for a wide temperature range application of acetonitrile-based supercapacitors. And the article contained the following:

A quasi-solid-state gel polymer electrolyte (GPE) is designed by integrating a free-standing cross-linked film and an injectable polymer electrolyte for applications in acetonitrile-based supercapacitors (SCs) using activated carbon (AC) electrodes. The synthesized GPE exhibits a high ionic conductivity over a wide temperature range (∼1.7 × 10-3 S cm-1 at -20°C to ∼7.9 × 10-3 S cm-1 at 60°C) as well as thermal stability and flexibility. A quasi-solid-state SC equipped with the GPE exhibits ∼13% higher specific capacitance (∼56% smaller Warburg resistance) at room temperature (RT) than that of an SC containing a corresponding liquid electrolyte. The quasi-solid-state SC also exhibits excellent electrochem. characteristics over a temperature range of -20 to 60°C with only ∼23% capacitance loss at -20°C compared to that at RT. Furthermore, the quasi-solid-state SC maintains ∼93% of its initial capacitance (only ∼4% increase in ESR) after 120-h storage at 85°C (above the b.p. of acetonitrile). This capacitance is superior to an SC equipped with a film-only GPE (∼73% capacitance retention and ∼270% increase in ESR). The proposed strategy provides new insights into the development of GPE designs for practical applications to solid-state SCs operating over a wide temperature range. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Reference of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)

On July 25, 2018, Blumel, Marcus; Nagasawa, Shota; Blackford, Katherine; Hare, Stephanie R.; Tantillo, Dean J.; Sarpong, Richmond published an article.Formula: C10H14O3 The title of the article was Rearrangement of Hydroxylated Pinene Derivatives to Fenchone-Type Frameworks: Computational Evidence for Dynamically-Controlled Selectivity. And the article contained the following:

An acid-catalyzed Prins/semipinacol rearrangement cascade reaction of hydroxylated pinene derivatives that leads to tricyclic fenchone-type scaffolds in very high yields and diastereoselectivity has been developed. Quantum chem. anal. of the selectivity-determining step provides support for the existence of an extremely flat potential energy surface around the transition state structure. This transition state structure appears to be ambimodal, i.e., the fenchone-type tricyclic scaffolds are formed in preference to the competing formation of a bornyl (camphor-type) skeleton under dynamic control via a post-transition state bifurcation (PTSB). The experimental process involved the reaction of (Trimethoxymethyl)benzene(cas: 707-07-3).Formula: C10H14O3
