And the article was included in Carbohydrate Polymers in 2013.Category: imidazoles-derivatives The following contents are mentioned in the article:

Isolation of cellulose from waste polyester/cotton blended fabrics (WBFs) is a bottleneck for recycling and exploiting waste textiles. The objective of this study was to provide a new environmental-friendly and efficient approach for extracting cellulose derivatives and polyester from WBFs. A Bronsted acidic ionic liquid (IL) N-methyl-imidazolium bisulfate, [Hmim]HSO₄, was used as a novel catalyst for acetylation of cellulose rather than a solvent with the aim to overcome low isolation efficiency associated with the very high viscosity and relatively high costs of ILs. The extraction yield of acetone-soluble cellulose acetate (CA) was 49.3%, which corresponded to a conversion of 84.5% of the cellulose in the original WBFs; meanwhile, 96.2% of the original poly(ethylene terephthalate) (PET) was recovered. The extracted CA was characterized by ¹H NMR, FTIR, XRD and TGA anal., and the results indicated that high purity acetone-soluble CA and carbohydrate-free PET could be isolated in this manner from WBFs. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Category: imidazoles-derivatives).

And the article was included in Journal of Solid State Chemistry in 2019.Application of 1374155-84-6 The following contents are mentioned in the article:

Long wavelength of near IR (NIR) room temperature phosphorescence (RTP) emission is a kind of highly desirable materials. With the self-assembly reaction of D-A-D type semi-rigid 3,5-bis(1-imidazoly)pyridine (BMP) organic ligand and Zn(II) ions, one ionic coordination polymer (CP) {[Zn_0.5(BMP)(H₂O)]·(NO₃)} (1) was synthesized and characterized. The as-synthesized 1 exhibits highly prolonged phosphorescence lifetime >6000 times as long as that of the pristine BMP phosphor ligand. Theory calculation indicates that NO₃^– counterions highly affect the electronic structure and energy levels of the cationic CP host. By a facile anionic exchange, Eosin Y (EY) dye guest encapsulated into the CP host can significantly tune the phosphorescence color from yellow to rare example of near IR emission through an efficient phosphorescence energy transfer. The optoelectronic performance of 1 and EY@1 also were studied.

Estimation of the viscosity of ionic liquids at room temperature using volumetric connectivity index was written by Xiong, Yan;Ding, Jing;Yu, Dahong. And the article was included in Jisuanji Yu Yingyong Huaxue in 2012.Electric Literature of C8H15F6N2P The following contents are mentioned in the article:

Ionic Liquids (ILs) have been considered as good green replacements for conventional volatile organic solvents due to their unique environment-friendly characteristics. Viscosity data as one of the most important thermodn. data needed for solvents are still in the scarcity for ILs. Although a large amount of exptl. data have been measured and reported, some appropriate theor. models that are crucial for the design and optimization of chem. processes are required to correlate and predict thermodn. properties. In recent years, many efforts including group contribution and connectivity index were attributed to develop thermodn. models to estimate the viscosity of ILs. In this article, a new approach named volumetric connectivity index (VCI) based on the phys. observable volume of groups and the concept of mol. connectivity index was proposed for the prediction of the viscosity of ILs. Viscosities at room temperature of 90 pure ILs were estimated by this new model and the average devation was only 5.95%, R² and rmsd were 0.9905 and 21cP, resp.

Patients with hematol. malignancies are at increased risk of severe COVID-19 outcomes due to compromised immune responses, but the insights of these studies have been compromised due to intrinsic limitations in study design. We present the PROSECO prospective observational study (NCT04858568) on 457 patients with lymphoma that received 2 or 3 COVID-19 vaccine doses. We show undetectable humoral responses following 2 vaccine doses in 52% of patients undergoing active anticancer treatment. Moreover, 60% of patients on anti-CD20 therapy had undetectable antibodies following full vaccination within 12 mo of receiving their anticancer therapy. However, 70% of individuals with indolent B-cell lymphoma displayed improved antibody responses following booster vaccination. Notably, 63% of all patients displayed antigen-specific T-cell responses, which increased after a 3rd dose irresp. of their cancer treatment status. Our results emphasize the urgency of careful monitoring of COVID-19-specific immune responses to guide vaccination schemes in these vulnerable populations.
