The deposition and sintering of nanoparticles (NPs) containing both Cu and Mn could be an economically and tech. interesting alternative to current processes for the metalization of through Si vias (TSVs). The authors propose to use ionic liquids (ILs) to (i) synthesize suspensions of suitable NPs and (ii) spread and anneal those suspensions directly on technol. substrates. Indeed, ILs readily stabilize NPs and possess good thermal stability. Suspensions of metallic Cu and MnO are formed upon decomposition of solutions of selected Cu and Mn precursors in an IL, C1C4ImNTf2. Upon decomposition of mixed solutions of both precursors, single populations of NPs are obtained, a good indication that both elements are incorporated in these NPs. Finally, upon spreading and annealing these suspensions on samples coated with SiO2, typical of TSV technol., a partial reduction of SiO2 is observed, in agreement with the formation of a MnSiO3 phase typical of self-formed barriers.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Heinemann, Ute; Engels, Dirk; Buerger, Sibylle; Kiziak, Christoph; Mattes, Ralf; Stolz, Andreas researched the compound: 2-Methylglutaronitrile( cas:4553-62-2 ).Quality Control of 2-Methylglutaronitrile.They published the article 《Cloning of a nitrilase gene from the cyanobacterium Synechocystis sp. strain PCC6803 and heterologous expression and characterization of the encoded protein》 about this compound( cas:4553-62-2 ) in Applied and Environmental Microbiology. Keywords: nitrilase Synechocystis nitrile biotransformation. We’ll tell you more about this compound (cas:4553-62-2).

The gene encoding a putative nitrilase was identified in the genome sequence of the photosynthetic cyanobacterium Synechocystis sp. strain PCC6803. The gene was amplified by PCR and cloned into an expression vector. The encoded protein was heterologously expressed in the native form and as a His-tagged protein in Escherichia coli, and the recombinant strains were shown to convert benzonitrile to benzoate. The active enzyme was purified to homogeneity and shown by gel filtration to consist probably of 10 subunits. The purified nitrilase converted various aromatic and aliphatic nitriles. The highest enzyme activity was observed with fumarodinitrile, but also some rather hydrophobic aromatic (e.g., naphthalenecarbonitrile), heterocyclic (e.g., indole-3-acetonitrile), or long-chain aliphatic (di-)nitriles (e.g., octanoic acid dinitrile) were converted with higher specific activities than benzonitrile. From aliphatic dinitriles with less than six carbon atoms only 1 mol of ammonia was released per mol of dinitrile, and thus presumably the corresponding cyanocarboxylic acids formed. The purified enzyme was active in the presence of a wide range of organic solvents and the turnover rates of dodecanoic acid nitrile and naphthalenecarbonitrile were increased in the presence of water-soluble and water-immiscible organic solvents.

A compound: 28903-71-1, is researched, SMILESS is COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC, Molecular C48H38CoN4O4Journal, Article, ACS Nano called Molecular approach for engineering interfacial interactions in magnetic/topological insulator heterostructures, Author is Cuxart, Marc G.; Valbuena, Miguel Angel; Robles, Roberto; Moreno, Cesar; Bonell, Frederic; Sauthier, Guillaume; Imaz, Inhar; Xu, Heng; Nistor, Corneliu; Barla, Alessandro; Gargiani, Pierluigi; Valvidares, Manuel; Maspoch, Daniel; Gambardella, Pietro; Valenzuela, Sergio O.; Mugarza, Aitor, the main research direction is interfacial interaction magnetic topol insulator; X-ray magnetic circular dichroism; angle-resolved photoelectron spectroscopy; density functional theory; interfacial interactions; metal−organic molecules; scanning tunneling microscopy; topological insulators.Recommanded Product: 28903-71-1.

Controlling interfacial interactions in magnetic/topol. insulator heterostructures is a major challenge for the emergence of novel spin-dependent electronic phenomena. As for any rational design of heterostructures that rely on proximity effects, one should ideally retain the overall properties of each component while tuning interactions at the interface. However, in most inorganic interfaces, interactions are too strong, consequently perturbing, and even quenching, both the magnetic moment and the topol. surface states at each side of the interface. Here, we show that these properties can be preserved using ligand chem. to tune the interaction of magnetic ions with the surface states. By depositing Co-based porphyrin and phthalocyanine monolayers on the surface of Bi2Te3 thin films, robust interfaces are formed that preserve undoped topol. surface states as well as the pristine magnetic moment of the divalent Co ions. The selected ligands allow us to tune the interfacial hybridization within this weak interaction regime. These results, which are in stark contrast with the observed suppression of the surface state at the first quintuple layer of Bi2Se3 induced by the interaction with Co phthalocyanines, demonstrate the capability of planar metal-organic mols. to span interactions from the strong to the weak limit.

Glazkova, M. E.; Ageeva, T. A.; Rodina, Yu. S.; Koifman, O. I. published an article about the compound: 5,10,15,20-Tetrakis (4-methoxyphenyl)-21H,23H-porphine cobalt (II)( cas:28903-71-1,SMILESS:COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC ).Application of 28903-71-1. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:28903-71-1) through the article.

The article presents the results of the kinetics study of the cobalt porphyrins interaction with radical polymerization initiators – benzoyl peroxide and lauryl peroxide in solution by the spectrophotometric method. From disparate literature data, it is known that some metalloporphyrins can interact with benzoyl peroxide to form the tautomers of porphyrins – isoporphyrins. These compounds have a number of specific properties, for example, it can be catalysts of various processes. Perhaps the isoporphyrins formation is the reason for high activity of the initiating systems “”cobalt porphyrin – benzoyl peroxide”” in the polymerization of vinyl monomers. Cobalt(II)complexes of tetraphenylporphyrin, tetra-p-methoxyphenylporphyrin, 5,15-bis(4′-tert-butylphenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-p-butylporphyrin were selected as the objects of this study. The influence of the porphyrin ligand structure on the formation of cobalt isoporphyrins was estimated The interaction of cobalt (II) tetraphenylporphyrin and cobalt (II) tetra-para-methoxyphenylporphyrin with peroxides showed changes in the electronic absorption spectra of metalloporphyrins: deformation of the Soret band, reduction of the absorption band in the visible region, and the appearance of absorption bands in the near IR region. These changes are characteristic for metalloisoporphyrins. Data on the interaction of cobalt porphyrins with lauryl peroxide were obtained for the first time. The formation of isoporphyrins is possible with the different ratio of concentrations of reagents: with a lack of peroxide, with equimolar ratio, and also with a significant (100-fold) excess of peroxide. When 5,15-bis(4′-tert-butylphenyl)-3,7,13,17-tetramethyl-2,8,12,18-tetra-p-butylporphyrinate cobalt (II) reacted with peroxides, no isoporphyrinates were observed The article presents the effective reaction rate constants of the cobalt isoporphyrinates formation at 25°C.It is shown that the structure of both cobalt porphyrinates and organic peroxides affects the possibility and rate of isoporphyrins formation.

Author is Lee, Yae Won; Yang, Hee Chun; Kim, Geon-Joong.

This paper describes the very efficient and highly enantioselective ring opening of terminal epoxides with alkyl and arene sulfonic acid. The dinuclear chiral (salen) Co complexes bearing Lewis acids of Al, Ga and In catalyze the reaction enantioselectively in the presence of tetrabutylammonium chloride using tert-Bu Me ether as a solvent. The variation of the anion of the tetra Bu ammonium salt has significant impact on the reactivity and selectivity of the asym. ring opening of Ph glycidyl ether with p-toluenesulfonic acid. The order of reactivity and selectivity was found to be Cl- > l- > Br- > OH-. Strong synergistic effects of the different Lewis acid centers of Co-Al, Co-Ga and Co-In complexes were observed in the catalytic process. The dinuclear chiral salen catalyst containing AlCl3 was found to be most active and highly enantioselective (91% ee).

Previously, we reported on the discovery of a novel series of bicyclo[3.1.0]hexane fused thiophene derivatives that serve as potent and selective S1P1 receptor agonists. Here, we discuss our efforts to simplify the bicyclohexane fused thiophene head. In a first step the bicyclohexane moiety could be replaced by a simpler, less rigid cyclohexane ring without compromising the S1P receptor affinity profile of these novel compounds In a second step, the thiophene head was simplified even further by replacing the cyclohexane ring with an iso-Bu group attached either to position 4 or position 5 of the thiophene. These structurally much simpler headgroups again furnished potent and selective S1P1 agonists (e.g., 87), which efficiently and dose dependently reduced the number of circulating lymphocytes upon oral administration to male Wistar rats. For several compounds discussed in this report lymphatic transport is an important route of absorption that may offer opportunities for a tissue targeted approach with minimal plasma exposure.

Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Toward New Solvents for EDLCs: From Computational Screening to Electrochemical Validation.

The development of innovative electrolytes is a key aspect of improving electrochem. double layer capacitors (EDLCs). New solvents, new conducting salts as well as new ionic liquids need to be considered. To avoid time-consuming “”trial and error”” experiments, it is desirable to “”rationalize”” this search for new materials. An important step in this direction is the systematic application of computational screening approaches. Via the fast prediction of the properties of a large number of compounds, for instance all reasonable candidates within a given compound class, such approaches should allow to identify of the most promising candidates for subsequent experiments In this work we consider the toy system of all reasonable nitrile solvents up to 12 heavy atoms. To investigate if our recently proposed computational screening strategy is a feasible tool for the purpose of rationalizing the search for new EDLC electrolyte materials, we correlate-in the case of EDLCs for the first time-computational screening results with exptl. findings. For this, experiments are performed on those compounds for which exptl. data is not available from the literature. We find that our screening approach is well suited to pick good candidates out of the set of all reasonable nitriles, comprising almost 5000 compounds
