《Boosting visible-light hydrogen evolution of covalent-organic frameworks by introducing Ni-based noble metal-free co-catalyst》 was written by Dong, Hong; Meng, Xiang-Bin; Zhang, Xin; Tang, Hong-Liang; Liu, Jun-Wang; Wang, Jian-Hui; Wei, Jin-Zhi; Zhang, Feng-Ming; Bai, Lin-Lu; Sun, Xiao-Jun. Synthetic Route of C9H6O6 And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020. The article conveys some information:

Covalent-organic frameworks (COFs) have been recognized as an emerging type of photocatalysts for H2 evolution and some of them have shown really outstanding photocatalytic activity with the help of Pt co-catalyst. To avoid the utilization of noble metal in COF-based photocatalysts, for the first time, we designed and constructed a series of nickel hydroxide-modified COF (TpPa-2) composite materials Ni(OH)2-X%/TpPa-2 (X: molar fraction of Ni(OH)2), which show apparently improved photocatalytic H2 evolution activity than that of the parent COF and the activity is comparable to that with Pt (0.3 wt%) co-catalyst. A series of Ni(OH)2-X%/TpPa-2 were prepared by in-situ adding TpPa-2 into the reaction system of Ni(OH)2, and the resulting Ni(OH)2-X%/TpPa-2 exhibit a novel sandwich-like morphol. The results of photocatalytic hydrogen evolution under visible light irradiation show that the optimized photocatalytic H2-evolution rate for Ni(OH)2-2.5%/TpPa-2 is up to 1895.99μmol·h-1·g-1, which is about 26.3 times higher than that of the parent TpPa-2 and is one of the best performing 2D COF-based photocatalyst for H2 evolution. Further investigation confirm the improved activity should be attributed to the enhanced visible-light absorption of the composite materials contributed from Ni(OH)2 and the synergetic effect of Ni(OH)2 and metallic Ni derived from the in-situ reduction of Ni(OH)2, which promoted the separation of photogenerated electron-holes of the resulting materials. This work not only presents a series of new photocatalysts for efficient H2 evolution but also open an avenue for future design and synthesis of COF-based composite materials acting as a substitute of noble-metal-containing photocatalytic systems. In the experiment, the researchers used many compounds, for example, 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Synthetic Route of C9H6O6)

《Tandem Use of Optical Sensing and Machine Learning for the Determination of Absolute Configuration, Enantiomeric and Diastereomeric Ratios, and Concentration of Chiral Samples》 was written by De los Santos, Zeus A.; MacAvaney, Sean; Russell, Katina; Wolf, Christian. SDS of cas: 126456-43-7 And the article was included in Angewandte Chemie, International Edition in 2020. The article conveys some information:

We have developed an optical method for accurate concentration, er, and dr anal. of amino alcs. based on a simple mix-and-measure workflow that is fully adaptable to multiwell plate technol. and microscale anal. The conversion of the four aminoindanol stereoisomers with salicylaldehyde to the corresponding Schiff base allows anal. of the dr based on a change in the UV maximum at 420 nm that is very different for the homo- and heterochiral diastereomers and of the concentration of the sample using a hypsochromic shift of another absorption band around 340 nm that is independent of the analyte stereochem. Subsequent in situ formation of CuII assemblies in the absence and presence of base enables quantification of the er values for each diastereomeric pair by CD anal. Applying a linear programming method and a parameter sweep algorithm, we determined the concentration and relative amounts of each of the four stereoisomers in 20 samples of vastly different stereoisomeric compositions with an averaged absolute percent error of 1.7%. After reading the article, we found that the author used (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7SDS of cas: 126456-43-7)

(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Nitrous acid converts secondary amines (aliphatic or aromatic) to N-nitroso compounds (nitrosamines): R2NH + HNO2 → R2N―NO. Some nitrosamines are potent cancer-inducing substances, and their possible formation is a serious consideration when nitrites, which are salts of nitrous acid, are present in foods or pharmaceutical preparations. Tertiary amines give rise to nitrosamines more slowly; an alkyl group is eliminated as an aldehyde or ketone, along with nitrous oxide, N2O.SDS of cas: 126456-43-7

In 2022,Shohrat, Annanurov; Zhang, Mi; Hu, Hui; Yang, Xueying; Liu, Li; Huang, Hao published an article in International Journal of Greenhouse Gas Control. The title of the article was 《Mechanism study on CO2 capture by ionic liquids made from TFA blended with MEA and MDEA》.Quality Control of 3-Aminopropan-1-ol The author mentioned the following in the article:

Ionic liquids are presenting a great potential to increase the efficiency and reduce the cost of CO2 capture process. TFA was selected as anion in the produced ionic liquids to study its absorption capacity, and CO2 capture by [3-AP][TFA] and [MDEA][TFA] were tested under different conditions with various solvents such as water, MEA and MDEA. Results showed that ionic liquids blended with MEA improved the absorption capacity up to 0.50 mol CO2/mol absorbent, which was much higher than that of aqueous ionic liquid solution (less than 0.30 mol CO2/mol absorbent), and the aqueous solution of ionic liquids blended with MDEA could improve its absorption capacity up to 0.93 mol CO2/mol absorbent. Different ratios of ionic liquids blended with MDEA were investigated, and ratios of ionic liquids vs. MDEA was set from 2:1 to 1:6. The CO2 absorption capacity reached the maximum of 0.91 mol CO2/mol IL at ratio 1:6 for [3-AP][TFA] and 0.93 mol CO2/mol IL at ratio 1:4 for [MDEA][TFA], which indicated that the CO2 absorption capacity increased with ascending amount of MDEA. Characterizations of aqueous blends were performed by FT-IR and 13C NMR, which showed that the formation of bicarbonate was observed, indicating the mechanism of CO2 absorption was a two-step reaction via the formation of zwitterion. The produced zwitterions contributed to CO2 absorption by increasing both the capacity and reaction rate. Reaction of MDEA with CO2 in water was considered to be a catalyzed hydrolysis, because the lack of eliminating hydrogen atom prevented MDEA from forming carbamate but produced bicarbonate instead. In the experiment, the researchers used many compounds, for example, 3-Aminopropan-1-ol(cas: 156-87-6Quality Control of 3-Aminopropan-1-ol)

3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Quality Control of 3-Aminopropan-1-ol

In 2022,Li, Yu-Hang; Wang, Chong-Chen; Zeng, Xu; Sun, Xue-Zi; Zhao, Chen; Fu, Huifen; Wang, Peng published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《Seignette salt induced defects in Zr-MOFs for boosted Pb(II) adsorption: universal strategy and mechanism insight》.Application In Synthesis of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The author mentioned the following in the article:

Within this work, a green and facile approach was proposed to modulate NH2-UiO-66 for purpose of obtaining SS-NH2-UiO-66-X (“”X”” implied the dosage of used SS) using seignette salt (SS). The generation of abundant vacancies with the formation of hierarchical pores boosted their sorption performance for lead (Pb(II)), which strengthened the mass transfer of Pb(II) in SS-NH2-UiO-66-X interior. Particularly, the optimal SS-NH2-UiO-66-5 exhibited good adsorption capacity toward Pb(II) (186.14 mg g-1) and fast diffusion rate (32.1 mg g-1·min0.5) at 25°C and initial pH = 5.46, which were about 34.2 and 66.9 times higher than those of the pristine NH2-UiO-66, resp. SS-NH2-UiO-66-5 could selectively capture the Pb(II) from simulated wastewater containing different co-existing ions. The mechanism was proposed that the defect sites played a significant role in boosting the Pb(II) capture performance, which was further affirmed by X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectra (XPS). The d. functional theory calculations (DFT calculations) illustrated that the hierarchical pores and rich vacancies enhanced the Pb(II) mobility toward the adsorption active sites and reduced the adsorption energy between SS-NH2-UiO-66-X and Pb(II). This defect engineering approach could be introduced to modulate other Zr-MOFs like MOF-801, UiO-66 and MOF-808, which presented a general strategy to fabricate defective Zr-MOFs for the boosted adsorption performance toward pollutants removal from wastewater. In the experimental materials used by the author, we found Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Application In Synthesis of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate)
