The article was titled 《On the importance of the electric double layer structure in aqueous electrocatalysis》, and you may find the article in Nature Communications.COA of Formula: C10H20O5 The information in the text is summarized as follows:

To design electrochem. interfaces for efficient elec.-chem. energy interconversion, it is critical to reveal the elec. double layer (EDL) structure and relate it with electrochem. activity; nonetheless, this has been a long-standing challenge. Of particular, no mol.-level theories have fully explained the characteristic two peaks arising in the potential-dependence of the EDL capacitance, which is sensitively dependent on the EDL structure. We herein demonstrate that our first-principles-based mol. simulation reproduces the exptl. capacitance peaks. The origin of two peaks emerging at anodic and cathodic potentials is unveiled to be an electrosorption of ions and a structural phase transition, resp. We further find a cation complexation gradually modifies the EDL structure and the field strength, which linearly scales the carbon dioxide reduction activity. This study deciphers the complex structural response of the EDL and highlights its catalytic importance, which bridges the mechanistic gap between the EDL structure and electrocatalysis.

Ghasemisarabbadieh, Mostafa; Gizurarson, Sveinbjorn; Sveinbjornsson, Benjamin Ragnar published an article in 2021. The article was titled 《Effect of 18-Crown-6 on Oxytocin Stability in Aqueous Buffer Solutions》, and you may find the article in ACS Omega.Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane The information in the text is summarized as follows:

In this study, the effect of 18-crown-6 on the stability of oxytocin in aqueous solution was explored. The study found that while 12-crown-4 and 15-crown-5 do not stabilize oxytocin, 18-crown-6 does have a stabilizing effect in citrate/phosphate buffer at pH 4.5. However, in acetate buffer at the same pH, the presence of 18-crown-6 had a destabilizing effect, possibly leading to a different degradation pathway. Both the stabilizing and destabilizing effects, depending on the buffer used, are concentration dependent where a higher concentration of 18-crown-6 is linked to a stronger effect. It is hypothesized that this effect may be linked to 18-crown-6 binding to the protonated ammonium group of oxytocin. Upon changing the mobile phase used in high-performance liquid chromatog. experiments, we observed evidence supporting this binding hypothesis. When an acidic mobile phase was used (0.01% trifluoroacetic acid (TFA)), a partial shift in oxytocin retention time was observed for samples in acetate buffers in the presence of 18-crown-6 when using a 150 mm column (C18). The amount of the peak that shifted depended on the 18-crown-6 concentration used. A similar shift in oxytocin peak retention time was observed for samples in both acetate and citrate/phosphate buffers when using a 250 mm column (C18), but the peak completely shifted in those samples. When using an even more acidic mobile phase (0.1% TFA), the oxytocin peaks all had the same retention time again. UV and NMR spectroscopy experiments also showed that the presence of 18-crown-6 has an observable effect on the resulting oxytocin spectra. In the experiment, the researchers used many compounds, for example, 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Application In Synthesis of 1,4,7,10,13-Pentaoxacyclopentadecane)

Bonnin, Maxime A.; Feldmann, Claus published an article in 2021. The article was titled 《Insights of the Structure and Luminescence of Mn2+/Sn2+-Containing Crown-Ether Coordination Compounds》, and you may find the article in Inorganic Chemistry.Reference of 1,4,7,10,13-Pentaoxacyclopentadecane The information in the text is summarized as follows:

Crown-ether coordination compounds with Mn2+ and Sn2+ as cations and 12-crown-4, 15-crown-5, and 18-crown-6 as ligands are synthesized. Their luminescence properties and quantum yields are compared and correlated with their structural features. Thus, MnI2(15-crown-5) (1), MnCl2(15-crown-5) (2), [Mn(12-crown-4)2]2[N(Tf)2]2(12-crown-4) (3), Sn3I6(15-crown-5)2 (4), and SnI2(18-crown-6) (5) are obtained by an ionic-liquid-based reaction of MX2 (M: Mn, Sn; X: Cl, I) and the resp. crown ether. Whereas 1, 2, and 5 exhibit a centric coordination of Mn2+/Sn2+ by the crown ether, 3 and 4 show a sandwich-like coordination of the cation with two crown-ether mols. All title compounds show visible emission, whereof 1, 2, and 5 have good luminescence efficiencies with quantum yields of 47, 39, and 21%, resp. These luminescence properties are compared with recently realized compounds such as Mn3Cl6(18-crown-6)2, MnI2(18-crown-6), Mn3I6(18-crown-6)2, or Mn2I4(18-crown-6), which have significantly higher quantum yields of 98 and 100%. Based on a comparison of altogether nine crown-ether coordination compounds, the structural features can be correlated with the luminescence efficiency, which allows extraction of those conditions encouraging intense emission and high quantum yields. The results came from multiple reactions, including the reaction of 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Reference of 1,4,7,10,13-Pentaoxacyclopentadecane)

Yin, Jie; Zhang, Jinrui; Wang, Chao; Lv, Naixia; Jiang, Wei; Liu, Hui; Li, Hongping; Zhu, Wenshuai; Li, Huaming; Ji, Hongbing published their research in Journal of Molecular Liquids in 2021. The article was titled 《Theoretical insights into CO2/N2 selectivity of the porous ionic liquids constructed by ion-dipole interactions》.HPLC of Formula: 33100-27-5 The article contains the following contents:

Porous liquids, a new class of materials, containing solid pores and liquid properties, have greatly aroused attention. In terms of gas absorption, porous liquids exhibit excellent advantages. Nevertheless, a variety of reports still lack the understanding of its absorption mechanism at the mol. level. Herein, we have figured out the factors contributing to the formation of porous liquids made of porous organic cages that can be dissolved in the crown ether, and the absorption mechanism of carbon dioxide, as well as CO2/N2 selectivity. Through charge and Wiberg index anal., the results show that crown ethers can interact with alkali metals to form alkali metal complexes by ion-dipole interactions, the dominant driving force of which is electrostatic interaction rather than coordination effect. Besides, the metal complexes should be regarded as a whole entity, which increases the steric hindrance of the cations and greatly reduces the probability of the crown ether blocking the cavity. The porous organic cage does provide unoccupied pores for gas storage. Furthermore, compared with N2, cages prefer to absorb CO2 mainly through hydrogen bonding. It is hoped that this work can facilitate the design and synthesis of porous liquids for gas absorption and selectivity.

The article was titled 《Synthesis and Reactivity of Cationic Gallium(I) [12]Crown-4 Complexes》.Related Products of 33100-27-5 The article contains the following contents:

The synthesis and reactivity of a Ga(I) cationic complex using [12]crown-4 as a stabilizing ligand were explored. The synthesis of [Ga([12]crown-4)][GaCl4] was achieved in one step from com. available starting materials. Anion exchange was used to replace the reactive tetrachlorogallate anion for the perfluorophenylborate anion. [Ga([12]crown-4)][B(C6F5)4] was analyzed using XPS, which allowed for the classification of the Ga(I)-crown ether complex as electron-deficient. Reactions of the Ga(I)-crown ether complex with Cp*K and cryptand[2.2.2] demonstrated the facile synthesis of a known Ga(I) compound as well as the generation of new Ga(I) complexes, highlighting the use of the Ga(I)-crown ether complex as an effective starting material for new Ga(I) complexes.

《Study and reduction of matrix effects in flowing liquid anode – Atmospheric pressure glow discharge – Optical emission spectrometry》 was written by Greda, Krzysztof; Szymczycha-Madeja, Anna; Pohl, Pawel. Reference of 1,4,7,10,13-Pentaoxacyclopentadecane And the article was included in Analytica Chimica Acta in 2020. The article conveys some information:

The effect of different interfering elements, i.e., Na, K, Mg, Ca, Al, Cu, Fe, Mn, Ni, and Zn, on the anal. performance of flowing liquid anode atm. pressure glow discharge optical emission spectrometry (FLA-APGD OES) was extensively studied. In the presence of interfering ions, the emission from analytes was suppressed by ∼10% in the case of Hg and Tl, ∼20% for Cd and Ag, and up to ∼80% for Zn and Pb. This study revealed that interfering elements did not affect the atomization/excitation conditions, and the reason for the observed decrease in anal. response was the impaired efficiency of analytes transport from liquid to plasma phase. To reduce matrix effects, the use of different masking agents capable of complexing the interfering ions, e.g., organic acids, crown ethers, chelating agents, and other compounds, was studied. FLA-APGD appeared to be quite susceptible to the presence of masking agents and only their small amounts could be added (limiting the effectiveness of this approach). Despite this, it was possible to significantly reduce the matrix effects originating from transition metals and alkali/alk. earth metals. Based on the results presented herein, different sample treatment procedures, aimed at the minimization of matrix effects in microplasma excitation sources, can be developed. As an example, a method for the determination of trace amounts of Zn and Pb in the Fe-rich matrix was shown. Using the selected masking agents, the recovery of Zn and Pb was improved 5.6-fold (from 10.4 to 57.8%) and 2.8-fold (from 13.6 to 38.0%), resp. Despite the presence of Fe-rich matrix, the detection limits of Zn and Pb were quite low (0.1 and 0.8μg L-1, resp.) and they were apparently lower than offered by ICP OES.

Synthetic Route of C10H20O5In 2020 ,《Oriented proton-conductive nano-sponge-facilitated polymer electrolyte membranes》 appeared in Energy & Environmental Science. The author of the article were Liu, Xin; Zhang, Junfeng; Zheng, Chenyang; Xue, Jiandang; Huang, Tong; Yin, Yan; Qin, Yanzhou; Jiao, Kui; Du, Qing; Guiver, Michael D.. The article conveys some information:

Achieving high power output from proton exchange membrane fuel cells (PEMFCs) requires efficient proton transport in proton exchange membranes (PEMs). Since proton conductivity is closely related to membrane moisture content, operation at low relative humidity (RH) and elevated temperature has become a critical bottleneck for the practical application of PEMFCs due to severe PEM dehydration. While several strategies have sought to mitigate this, including external thermal and water management, coating of nano-cracked hydrophobic layers and optimization of membrane intrinsic water retention, only partial improvements have been realized. Here, using a membrane formulation of ferrocyano-coordinated poly(4-vinylpyridine) (CP4VP), phosphotungstic acid (PWA) and polysulfone (PSf), novel highly water-retentive PEMs are fabricated via a strong magnetic field. During magnetic-assisted membrane casting, CP4VP and PWA form a microporous Prussian blue analog (PBA) framework with the new type of Fe-C≡N-W bonding, which is paramagnetic and is thus simultaneously aligned in the through-plane (TP) direction of the membrane. The neutral PSf membrane component affords mech. strength to the embedded TP-aligned conducting channels. This new type of microporous PBA framework is highly hydrophilic and proton conductive, with micropores of ∼5.4 Å diameter, which act as nano-sponges to absorb only more retentive non-freezable water, effective for proton conduction. These nano-sponges display efficient water absorption and retention at low RH and elevated temperatures, together with a much faster hydration process than the dehydration process. Furthermore, the TP-aligned PBA channels also enable faster water transport to promote PEM proton conduction beyond any previously reported water-retentive membrane. Consequently, the novel nano-sponge-like PEMs exhibit remarkable performance in both ex situ and in situ evaluations, especially at low RH and elevated temperature, largely prevailing over the com. benchmark Nafion 212.

In this paper the continuation of our work on searching for anti crystallization additives to the aqueous solution of lithium bromide is presented. This type of research is important from the viewpoint of absorption refrigeration technol. to improve the performance of the efficiency of refrigeration equipment. In this study three crown ethers 12-crown-4 15-crown-5 and 18-crown-6 as well as the glycols ethylene glycol diethylene glycol triethylene glycol and glycerol were investigated as anti crystallization additives for lithiumbromide in water system, conventionally used as a working pair in absorption refrigeration technol. For this purpose the solubility of lithium bromide in water has been detected in the presence of the organic additive. The solubility measurements have been carried out using a dynamic method at a wide temperature and comparision range for different additive to LiBr initial mass fraction from 0.1 0.2 and 0.3. From exptl. SLE data the comparison range of the liquid state for tested systems at the absorbers working temperature was detected and compared to those from conventional LiBr in water system. Further measurements of vapor liquid equillibrium will be performed to select the best anti crystalization additive.

In 2019,Molecules (Basel, Switzerland) included an article by Chen, Ichen; Xu, Chenxi; Peng, Jing; Han, Dong; Liu, Siqi; Zhai, Maolin. Electric Literature of C10H20O5. The article was titled 《Novel Functionalized Cellulose Microspheres for Efficient Separation of Lithium Ion and Its Isotopes: Synthesis and Adsorption Performance.》. The information in the text is summarized as follows:

The adsorption of lithium ions(Li+) and the separation of lithium isotopes have attracted interests due to their important role in energy storage and nuclear energy, respectively. However, it is still challenging to separate the Li+ and its isotopes with high efficiency and selectivity. A novel cellulose-based microsphere containing crown ethers groups (named as MCM-g-AB15C5) was successfully synthesized by pre-irradiation-induced emulsion grafting of glycidyl methacrylate (GMA) and followed by the chemical reaction between the epoxy group of grafted polymer and 4′-aminobenzo-15-crown-5 (AB15C5). By using MCM-g-AB15C5 as adsorbent, the effects of solvent, metal ions, and adsorption temperature on the adsorption uptake of Li+ and separation factor of 6Li/7Li were investigated in detail. Solvent with low polarity, high adsorption temperature in acetonitrile could improve the uptake of Li+ and separation factor of lithium isotopes. The MCM-g-AB15C5 exhibited the strongest adsorption affinity to Li+ with a separation factor of 1.022 ± 0.002 for 6Li/7Li in acetonitrile. The adsorption isotherms in acetonitrile is fitted well with the Langmuir model with an ultrahigh adsorption capacity up to 12.9 mg·g-1, indicating the unexpected complexation ratio of 1:2 between MCM-g-AB15C5 and Li+. The thermodynamics study confirmed the adsorption process is the endothermic, spontaneous, and chemisorption adsorption. As-prepared novel cellulose-based adsorbents are promising materials for the efficient and selective separation of Li+ and its isotopes. In the experiment, the researchers used many compounds, for example, 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Electric Literature of C10H20O5)
