The article contains the following contents:

Rare earth metal oxides are known to have good catalytic effectiveness in the direct synthesis of di-Me carbonate (DMC) from CO₂ and methanol. In this work, we screened ceria (CeO₂) catalysts by analyzing their capacity for CO₂ adsorption. The effects of the crystal surface morphol. and oxygen vacancy on the catalytic performance of the ceria catalyst were studied by using d. functional theory (DFT). The results show that the (110) surface and higher oxygen vacancy content can better promote the synthesis of DMC and that the rod-shaped CeO₂ catalyst has a better catalytic effect. The oxygen vacancy content on the catalyst was improved by freeze-drying and confirmed by thermogravimetric anal., Raman spectroscopy, and ESR. The freeze-dried CeO₂ (CeO₂-FD) then showed a higher catalytic performance. The conversion rate of methanol and the yield of DMC were 33.95% and 584 mmol g^-1cat, resp., under mild conditions (140°C and 1 MPa). The experimental procedure involved many compounds, such as 3-Cyanopyridine (cas: 100-54-9) .

Category: pyridine-derivatives《Millimeter-Scale Zn(3-ptz)₂ Metal-Organic Framework Single Crystals: Self-Assembly Mechanism and Growth Kinetics》 was published in 2021. The authors were Garcia-Garfido, Juan M.;Enriquez, Javier;Chi-Duran, Ignacio;Jara, Ivan;Vivas, Leonardo;Hernandez, Federico J.;Herrera, Felipe;Singh, Dinesh P., and the article was included in《ACS Omega》. The author mentioned the following in the article:

The solvothermal synthesis of metal-organic frameworks (MOFs) often proceeds through competing crystallization pathways, and only partial control over the crystal nucleation and growth rates is possible. It challenges the use of MOFs as functional devices in free-space optics, where bulk single crystals of millimeter dimensions and high optical quality are needed. We develop a synthetic protocol to control the solvothermal growth of the MOF [Zn(3-ptz)₂]_n (MIRO-101), to obtain large single crystals with projected surface areas of up to 25 mm² in 24 h, in a single reaction with in situ ligand formation. No addnl. cooling and growth steps are necessary. We propose a viable reaction mechanism for the formation of MIRO-101 crystals under acidic conditions, by isolating intermediate crystal structures that directly connect with the target MOF and reversibly interconverting between them. We also study the nucleation and growth kinetics of MIRO-101 using ex situ crystal image anal. The synthesis parameters that control the size and morphol. of our target MOF crystal are discussed. Our work deepens our understanding of MOF growth processes in solution and demonstrates the possibility of building MOF-based devices for future applications in optics. To complete the study, the researchers used 3-Cyanopyridine (cas: 100-54-9) .

Product Details of 100-54-9《Proximity Effect in Uranyl Coordination of the Cucurbit[6]uril-Bipyridinium Pseudorotaxane Ligand for Promoting Host-Guest Synergistic Chelating》 was published in 2021. The authors were Li, Fei-ze;Geng, Jun-shan;Hu, Kong-qiu;Yu, Ji-pan;Liu, Ning;Chai, Zhi-fang;Mei, Lei;Shi, Wei-qun, and the article was included in《Inorganic Chemistry》. The author mentioned the following in the article:

The authors proposed regulating uranyl coordination behavior of cucurbituril-bipyridinium pseudorotaxane ligand by using meta-functionalized bipyridinium dicarboxylate guest. A tailored pseudorotaxane precursor involving 1,1′-(hexane-1,6-diyl)bis(3-cyanopyridin-1-ium) bromide (C6BPCN3) and cucurbit[6]uril (CB[6]) has been designed and synthesized. Through in situ hydrolysis of the pseudorotaxane ligands and their coordination assembly with uranyl cations, seven new uranyl-rotaxane coordination polymers URCP1-URCP7 were obtained under hydrothermal conditions in the presence of different anions. The variation of carboxylate groups from para- to meta-position affected the coordination of the meta-functionalized pseudorotaxane linkers, which are enriched from simple guest-only binding to host-guest simultaneous coordination and synergistic chelating. This effective regulation on uranyl coordination of supramol. pseudorotaxane can be attributed to the proximity effect, which refers to the meta-position carboxyl group being spatially closer to the portal carbonyl group of CB[6]. Also, by combining other regulation methods such as introducing competing counterions and modulating solution acidity, the nuclearity of the uranyl center and the coordination patterns of the pseudorotaxane ligand can be diversely tuned, which subsequently exert great influence on the final dimensionality of resultant uranyl compounds This work presents a large diversity of uranyl-based coordination polyrotaxane compounds with fascinating mech. interlocked components and, most importantly, provides a feasible approach to adjust and control the metal coordination behavior of the pseudorotaxane ligand that might expand the scope of application of such supramol. ligands.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.

The research results were published in《International Biodeterioration & Biodegradation》 in 2021.Quality Control of 3-Cyanopyridine The article conveys some information:

Acetamiprid is a neonicotinoid insecticide used worldwide that has caused environmental pollution and adverse effects on ecosystems. Here, a novel bacterium, Pseudaminobacter salicylatoxidans CGMCC 1.17248, was isolated to rapidly degrade acetamiprid to IM-1-2 via hydration. Gene cloning and overexpression demonstrated that two nitrile hydratases, AnhA and AnhB, converted acetamiprid to IM-1-2. Escherichia coli overexpressing AnhA and AnhB degraded 98.1% and 94.0% of acetamiprid (1.0 mmol L^-1) in 5 min and 8 h, resp. The pure AnhA and AnhB had a V_max value of 14.12 and 1.20 μmol mg^-1 min^-1, resp., and a Km value of 1.02 mmol L^-1 and 2.95 mmol L^-1, resp. Compared with AnhA, AnhB had broad pH stability, as well as metal ions and organic solvents tolerance. Expression of AnhA and AnhB was induced by decreasing the nutrient concentration of culture broth and addition of urea and therefore significantly enhanced acetamiprid degradation of CGMCC 1.17248. qPCR indicated that the expression of AnhA and AnhB under the cultured conditions of 1/15 lysogeny broth or 0.5% urea addition was improved by from 2.2 to 5.3 times. The results presented herein will facilitate development of bioremediation agents for acetamiprid pollution and understanding of the functional role of bacterial nitrile hydratase.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.

The article contains the following contents:

Aerobic visible-light induced intermol. S-N bond construction has been achieved without the addition of photosensitizer, metal, or base. With this strategy, 1,2,4-thiadiazoles I (R = Ph, 4-methoxyphenyl, thiophen-3-yl, etc.; R¹ = 4-methoxyphenyl, 2,6-dimethylphenyl, thiophen-2-yl, etc.) can be obtained from thioamides R/R¹C(S)NH₂. Preliminary mechanistic investigation suggested that the excited state of thioamides undergoes a single-electron-transfer (SET) process to afford thioamidyl radicals, which can be further transformed into a 1,2,4-thiadiazole through desulfurization and oxidative cyclization. The reaction has good functional group tolerance and represents a green method for the construction of S-N bonds.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.
