Onion-like graphitic structures are of great importance in different fields. Pentagons, heptagons, and octagons are essential features of onion-like graphitic structures that could generate important properties for diverse applications such as anodes in Li metal batteries or the oxygen reduction reaction. These carbon nanomaterials are fullerenes organized in a nested fashion. In this work, we produced graphitic nano onion-like structures containing phosphorus and nitrogen (NP-GNOs), using the aerosol assisted chem. vapor deposition method. The NP-GNOs were grown at high temperature (1020 °C) using ferrocene, trioctylphosphine oxide, benzylamine, and THF precursors. The morphol., structure, composition, and surface chem. of NP-GNOs were characterized using different techniques. The NP-GNOs showed diameters of 110-780 nm with Fe-based nanoparticles inside. Thermogravimetric anal. showed that NP-GNOs are thermally stable with an oxidation temperature of 724 °C. The surface chem. anal. by FTIR and XPS revealed phosphorus-nitrogen codoping, and several functionalities containing C-H, N-H, P-H, P-O, P = O, C = O, and C-O bonds. We show d. functional theory calculations of phosphorus-nitrogen doping and functionalized C240 fullerenes. We present the optimized structures, electronic d. of states, HOMO, and LUMO wave functions for P-doped and OH-functionalized fullerenes. The P = O and P-O bonds attributed to phosphates or hydroxyl groups attached to phosphorus atoms doping the NP-GNOs could be useful in improving supercapacitor function.

Name: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium, is researched, Molecular C18H28ClRu, CAS is 92390-26-6, about Biscarbene-Ruthenium Complexes in Catalysis: Novel Stereoselective Synthesis of (1E,3E)-1,4-Disubstituted-1,3-dienes via Head-to-Head Coupling of Terminal Alkynes and Addition of Carboxylic Acids. Author is Le Paih, Jacques; Monnier, Florian; Derien, Sylvie; Dixneuf, Pierre H.; Clot, Eric; Eisenstein, Odile.

The reaction of a variety of alkynes RCCH with a variety of carboxylic acids R1CO2H, in the presence of 5% of RuCl(COD)C5Me5, selectively leads to the dienyl esters (1E,3E)-RCH1:CH2-CH3:C(R)(O2CR1). The reaction also applies to amino acid and dicarboxylic acid derivatives It is shown that the first step of the reaction consists of the head-to-head alkyne coupling and of the formation of the metallacyclic biscarbene-ruthenium complex cyclo-(C5Me5)(Cl)Ru:C(R)-CH:CH-C:(R), isolated for R = Ph and catalyzing the formation of dienyl ester. D-labeled reactions show that the alkyne protons remain at the alkyne terminal carbon atoms and carboxylic acid protonates the C1 carbon atom. QM/MM (ONIOM) calculations, supporting a mixed Fischer-Schrock-type biscarbene complex, show that protonation occurs preferentially at the carbene carbon C1 adjacent to Ru, in the relative cis position with respect to the Ru-Cl bond, to give a mixed C(1)alkyl-C(4)carbene complex in which the C4 carbene is conjugated with the noncoordinated C2:C3 double bond. This 16-electron intermediate has a weak stabilizing α agostic C-H bond. This most stable isomer appears to have a C4 center more accessible to the nucleophilic addition which accounts for the exptl. observed product.

Application In Synthesis of Tri-n-octylphosphine Oxide. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Tri-n-octylphosphine Oxide, is researched, Molecular C24H51OP, CAS is 78-50-2, about Impact on Structural, Morphological, and compositional properties of CZTS thin films annealed in different environments. Author is Jain, Shefali; Kumar Swami, Sanjay; Dutta, Viresh; Narain Sharma, Shailesh.

The present study focuses on the impacts of annealing temperature in different ambiances on the morphol. behavior and thin-film quality of CZTS nanoparticles. CZTS nanoparticles were synthesized via the hot-injection colloidal route method. CZTS nanoparticles were annealed in air, vacuum atm., and S environment (N2 + H2S 5%), resp. at 450° for 30 min. The structural, morphol., compositional, and optical properties of all CZTS thin films were analyzed. The volume fraction is increased in the vacuum annealed thin film keeping crystallite size as same as in the as-deposited film. This results in a reduction of cracks and voids and thus the surface defects of the vacuum annealed thin film as confirmed by scanning electron microscope (SEM). AFM also confirms the improved quality of CZTS thin film annealed in a vacuum. PL curves also confirm the min. defects in the case of vacuum-annealed thin films. Thus, the study reveals that the best quality CZTS thin films i.e. films with the least pinholes, cracks, and voids without any significant change from the initial conditions can be obtained after annealing in the vacuum environment.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:78-50-2) here.

This study investigated imidazolium ionic liquids capability under ultrasonic irradiation conditions for dysprosium extraction from the aqueous nitrate solution The main objective was to evaluate the feasibility of ultrasound-assisted extraction techniques compared to conventional solvent extraction The extraction process was investigated as a function of the ionic liquids and organic extractant, organic/aqueous phase volume ratio, the acidity of the aqueous phase, contact time, ion concentration, temperature, and stripping condition. The outcomes demonstrated that the combination of C6MIM.PF6 and TOPO extractant is more extractable than the mixture of C6MIM.NTf2 and TOPO. The effects of ultrasonic irradiation on the Dy(III) ions show that ion transfer occurs with high extraction efficiency. The variation of logD vs. temperature demonstrated that temperature had little impact on the extraction procedure. The recovery of dysprosium ions from the organic phase using 0.5 M nitric acid is achieved in stripping studies. The results showed that the extraction and recovery under ultrasonic irradiation and with the presence of ionic liquids proposed a simple and environmentally friendly approach for the purification and separation of rare-earth ions from the permanent magnet wastewater.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Tri-n-octylphosphine Oxide, is researched, Molecular C24H51OP, CAS is 78-50-2, about Quantitative detection of parathyroid hormone using europium complex doped silica nanoparticles.Category: catalyst-palladium.

Parathyroid hormone (PTH) is a hormone that plays a critical role in bone remodeling because it regulates the calcium levels. Either higher or lower than normal range of PTH release can cause serious metabolic disorders such as hyperparathyroidism or hypoparathyroidism. Therefore, the demand of highly sensitive monitoring sensor of PTH is on the rise. However, due to its presence of small size and low concentration in serum, the monitoring of a small change of PTH level is extremely difficult. In this article, we suggested the fabrication of europium complex doped nanoparticles conjugated with PTH antibodies for the sensitive fluorescence monitoring of PTH. For the synthesis of europium complex, 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (NTA) and trioctylphosphine oxide (TOPO) are used to encapsulate europium. The amphiphilic polymer, polyvinylpyrrolidone (PVP), was applied to hydrophobic europium complex, and then silica shell was synthesized on the complex. Using the europium complex doped silica nanoparticles, we could obtain approx. 4.24-fold enhanced fluorescence in low levels of PTH in PBS, when compared to the conventional ELISA (ELISA). In addition, we could obtain the sensitive PTH immunoassay in PTH spiked serum with high selectivity.

Multicomponent supramol. assembly systems enable the generation of materials with outstanding properties, not obtained from single-component systems, via a synergetic effect. A novel supramol. coassembly system is demonstrated, rendering highly ordered quantum dot (QD) arrangement structures formed via the self-assembly of azobenzene derivatives, where the photocontrollable luminescence (PL) properties of the QDs are realized based on photoisomerization. Upon mixing the assembled azobenzene derivatives and QDs in apolar media, a time-evolution coaggregation into hierarchical nanosheets with a highly ordered QD arrangement structure occurs. Upon photoirradiation, the nanosheets transform into ill-defined aggregates without arranged QDs together with enhancing the PL intensity. In days, the photoirradiated coaggregates undergo recovery of the PL properties corresponding to the arranged QDs through thermal isomerization.
