Double deprotonation of the salt [Ph2B(PMe3)(2)]-[OTf] (1) provides access to a bis(ylide)diphenylborate ligand that is readily transferred in situ to iron(II). Depending on the reaction stoichiometry, both the ate complex [Ph2B(Me2PCH2)(2)Fe(mu- Cl)(2) Li(THF)(2)] (2) and the homoleptic complex [Ph2B(Me2PCH2](2)Fe (3) can be prepared from FeCl2(THF)(1.5). Further reaction of 3 with FeCl2.(THF)1.5 produces the chloride-bridged dimer [Ph2B(Me2PCH2)(2)Fe(mu-Cl)(2) Fe(CH2PMe2)(2)BPh2](4). At- tempts to reduce or alkylate 4 provide 3 as the only isolable product, likely a consequence of the low steric hindrance of the bis(ylide)diphenylborate ligand. On the other hand, reaction of 4 with the strong field ligand (CNBu)-Bu-t provides the six-coordinate, diamagnetic complex [Ph2B(Me2PCH2)(2)Fe((CNBu)-Bu-t)(4)][Cl](5). Electronic structure calculations for the bis(ylide)diphenylborate ligand and homoleptic complex 3 suggest that the C(ylide) atoms are strong sigma-donors with little pi-bonding character. These initial results suggest the potential for this bis(ylide)diphenylborate ligand in coordination chemistry.

Evaluating the corrosion performances of wear resistant alloys is important for designing the molten salt-wetted bearings and valves in molten salt reactors. In this study, the corrosion behavior of wear-resistant Tribaloy T-400 alloy (Co-29Mo-8.5Cr-2.8Si) in molten FLiNaK salt (LiF-NaF-KF: 46.5-11.5-42 mol.%), with and without the presence of UNS N10 003 alloy, were investigated through static immersion tests at 650 degrees C. After 400 h corrosion, T-400 alloy showed greater weight loss than UNS N10 003 alloy, and the presence of UNS N10003 alloy further increased the weight loss of T-400 alloy. Electron microscopic and salt chemistry analyses showed that Cr and Co were selectively dissolved from T-400 alloy matrix after corrosion, resulting in a porous structure. On the other hand, the Laves phase precipitates were hardly corroded but showed signs of carbide formation on the surface. In addition, when tested with UNS N10 003 alloy, some of the Co dissolved from T-400 alloy transferred to the surface of UNS N10003 alloy, hence promoted the corrosion of T-400 alloy. The results have indicated that even T-400 alloy has a relatively low Cr content among high temperature wear-resistant hardfacing alloys, its corrosion resistance is still inadequate in a typical molten salt reactor environment where UNS N10003 alloy and graphite are also present.

The exposure temperature significantly affects the diffusion of chloride ions in concrete, and, as such, it must be taken into consideration in the development of service-life prediction models for structures exposed to chloride-bearing environments. Most of the earlier studies have used cement paste to assess the effect of exposure temperature on chloride diffusion. In the reported study, chloride diffusion in Type I and fly ash (20% fly ash) cement concrete was evaluated under field and laboratory conditions. The laboratory concrete specimens were exposed to chloride solution maintained at four temperatures (22, 35, 50 and 60 degrees C) for 365 days. Beam specimens were exposed in the tidal zone of a marine exposure site, along the Arabian Gulf coast, for up to 10 years to study the chloride diffusion in the field specimens. The coefficient of chloride diffusion (D-a) in the concrete specimens exposed to 22 or 35 degrees C in the laboratory was less than that in the concrete specimens exposed to 50 and 60 degrees C. The D-a for Type I cement concrete specimens increased by 3.6 times as the temperature was increased from 22 to 60 degrees C while this increase was 2.3 times for the fly ash cement concrete specimens for a similar increase in the temperature. The D-a decreased with the period of exposure in the field specimens. The values of activation energy that can be used for predicting the chloride diffusion for exposure temperature within the range of 22-60 degrees C were developed based on the laboratory data. In addition, mathematical models were developed relating the coefficient of chloride diffusion in the field and laboratory concrete specimens. The developed models can be utilized to ascertain chloride diffusion in field specimens, utilizing the laboratory values, and hence calculate the useful service-life of structures.

Highly stable antioxidant dispersions were designed on the basis of ring-opened ellagic acid (EA) intercalated into MgAl-layered double hydroxide (LDH) nanoparticles. The morphology of the composite was delicately modified with ethanolic washing to obtain EtOH-EA-LDH with a high specific surface area. The colloidal stability was optimized by surface functionalization with positively charged polyelectrolytes. Polyethyleneimine (PEI), protamine sulfate (PS) and poly(acrylamide-co-diallyl dimethyl ammonium chloride) (PAAm-co-DADMAC) was adsorbed onto the surface of the oppositely charged EtOH-EA-LDH leading to charge neutralization and overcharging at appropriate doses. Formation of adsorbed polyelectrolyte layers provided remarkable colloidal stability for the EtOH-EA-LDH. Modification with PEI and PAAm-co-DADMAC outstandingly improved the resistance of the particles against salt-induced aggregation with a critical coagulation concentration value above 1 M, while only limited stability was achieved by covering the nanoparticles with PS. The high antioxidant activity of EtOH-EA-LDH was greatly preserved upon polyelectrolyte coating, which was proved in the scavenging of radicals in the test reaction applied. Hence, an active antioxidant nanocomposite of high drug dose and remarkable colloidal stability was obtained to combat oxidative stress in systems of high electrolyte concentrations.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 638-07-3. Recommanded Product: 638-07-3.

Magnesium hydride (MgH2) is one of the competitive hydrogen storage materials on account of abundant reserves and high hydrogen content. The hydrolysis of MgH2 is an ideal and controllable chemical hydrogen generation process. However, the hydrolyzed product of MgH2 is a passivation layer on the surface of the magnesium hydride, which will make the reaction continuity worse and reduce the rate of hydrogen release. In this work, hydrogen generation is controllably achieved by regulating the change of the surface tension value in the hydrolysis, a variety of surfactants were systematically investigated for the effect of the hydrolysis of MgH2 In the meantime, the passivation layer of MgH2 was observed by scanning electron microscope (SEM), and the surface tension value of the solution with different surfactants were monitored, investing the mechanism of hydrolysis adding different surfactants. Results show that different surfactants have different effects on hydrogen generation. The hydrogen generation capacity from high to low is as follows: tetrapropylammonium bromide (TPABr), sodium dodecyl benzene sulfonate (SDBS), Ecosol 507, octadecyl trimethyl ammonium chloride (OTAC), sodium alcohol ether sulfate (AES), and fatty methyl ester sulfonate (FMES-70). When the ratio of MgH2 to TPABr was 5 : 1, the hydrogen generation was increased by 52% and 28.3%, respectively, at the time of 100 s and 300 s. When hydrolysis time exceeds 80 s, the hydrogen generation with AES and FMES-70 began to decrease; it was reduced by more than 20% at the time of 300 s. SEM reveals that surfactants can affect the crystalline arrangement of Mg(OH)(2) and make the passivation layer three-dimensionally layered providing channels for H2O molecules to react with MgH2.

Nanocarbons as alternatives to metal-based catalysts have attracted great interest in heterogeneous catalysis. However, the powder form of nanocarbons limits their industrial applications because of the large pressure drop in a fixed-bed reactor and the big difficulties in handling loose powder in a fluidized-bed reactor. To address these issues, herein, we report a general poly(imidazolium-methylene)-assisted grinding strategy for synthesizing mechanically robust nanocarbon-embedded network monoliths by grinding a mixture composed of nanocarbons and the as-formed poly(imidazolium-methylene) chloride (PImM) with a subsequent pyrolysis process. The as-prepared nanocarbon-based network monoliths feature nanocarbons to be well-dispersed within a N-doped carbon (NC) network. The monolith is adequately hard and high density and can be cracked and sieved into granule nanocarbon catalysts. Taking nanodiamonds (NDs) as an example, in the grinding procedure, PImM can penetrate into ND aggregates to disperse NDs and can adhere the deagglomerated NDs because there is a strong interaction between NDs and PImM through strong cation-p interactions, pi-pi interactions, and electrostatic interactions since many nanocarbons including NDs have negative charges on their surface. The designed PImM plays three roles in the preparation of ND-embedded network monolith including the adhering agent, isolating agent, and a precursor of the NC network. The resulting granule ND@NC carbocatalyst from its corresponding ND@NC network monolith shows 6.39 mmol g(-1) h(-1) of steady-state styrene rate (9.26 and 2.24 times higher compared to that of NC and ND, respectively) with 99.0% of styrene selectivity for ethylbenzene direct dehydrogenation (EDH) to styrene, a commercially important reaction. The granule ND@NC carbocatalyst also shows high catalytic stability for EDH reaction. The strategy has been extended to carbon nanofiber-embedded monoliths. This work not only creates a granule carbocatalyst for styrene production via EDH reaction but also paves an avenue to overcome the bottleneck problems regarding the applications of the powders of diverse nanocarbons in heterogeneous catalysis.

Thermodynamic properties of some neoteric three-component deep eutectic solvents (DESs) and their mixture with water are of great practical and fundamental importance in various fields of sciences. In this work the measurements of density and speed of sound data for neat four DESs (choline chloride/lactic acid/ethylene glycol, choline chloride/lactic acid/glycerol, choline chloride/oxalic acid/ethylene glycol and choline chloride/oxalic acid/glycerol) and their aqueous mixture were carried out over the entire composition range at T = (288.15 to 318.15) K. Some of the thermodynamic properties including the excess molar volumes (V-E), the apparent molar volumes (V-phi,V-1 and V-phi,V-2), excess isobaric thermal expansion (alpha(E)(p, m)), the isentropic compressibility deviation (Delta kappa(s)) and speed of sound deviation (Delta u) were computed based on these data. These main properties were evaluated according to numerous solute-solvent interactions among the various components in the mixtures for all of the investigated systems. In addition, the properties were fitted by the Redlich-Kister and Hwang equations. Finally, the capability of Prigogine-Flory-Patterson (PFP) theory for reproducing the main experimentally observed properties of the investigated systems containing DESs. The binary interaction parameter chi(12) of PFP theory are negative and these represent the stronger interactions between the components (DESs + water), as compared to the self-interactions among the pure components in the systems.

A series of mononuclear gold(iii) complexes of the general formula [AuCl3(diazanaphthalene)], where diazanaphthalene is quinazoline (qz, 1), phthalazine (phtz, 2), 1,5-naphthyridine (1,5-naph, 3), 1,6-naphthyridine (1,6-naph, 4) or 1,8-naphthyridine (1,8-naph, 5), were prepared and fully characterized. The complexes 1-5 consist of discrete monomeric species with the Au(iii) cation in a square planar coordination geometry surrounded by three chloride anions and one diazanaphthalene ligand. Crystallographic studies indicate the presence of an extended 4 + 1 or 4 + 2 geometry around the square planar [AuCl3(diazanaphthalene)] center due to AuMIDLINE HORIZONTAL ELLIPSISCl and AuMIDLINE HORIZONTAL ELLIPSISN interactions. The crystal structures of these complexes are controlled by a variety of intermolecular interactions that utilize the amphiphilic properties of the coordinated chloride anions and involve C-H groups, pi-electrons, and an uncoordinated nitrogen atom of the diazanaphthalene ligand. The usual offset pi-stacking between the N-heteroaromatic ligands appears to be completely hindered between the 1,5-naph fragments and significantly weakened between the 1,6-naph and 1,8-naph in their respective complexes 3, 4 and 5, for which the average molecular polarizability (alpha) values are the lowest in the series. It is remarkable that the [AuCl3(benzodiazine)] complexes 1 and 2 form centrosymmetric crystals, but the [AuCl3(naphthyridine)] complexes 3-5 assemble into non-centrosymmetric aggregates, making them potential alternatives to the previously studied systems for application in various fields by taking advantage of their polarity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

The risk of extensive exposure of the human epidermis to solar ultraviolet radiation is significantly increased nowadays. It not only induces skin aging and solar erythema but also increases the possibility of skin cancer. Therefore, a simply prepared, highly sensitive, and optically readable device for monitoring the solar ultraviolet radiation is highly desired for the skin health management. Because of the photoinitiated polymerization triggered by graphene-carbon nitride (g-C3N4) under ultraviolet radiation, g-C3N4 is homogeneously distributed in the hybrid hydrogels containing N-isopropylacrymide (NIPAM), poly(ethylene glycol) methyl ether methacrylate (OEGMA(300)), and sodium alginate (SA). By further immersing the hybrid hydrogels into calcium chloride solution, hybrid alginate-Ca2+/P(NIPAM-co-OEGMA(300))/g-C3N4 interpenetrating polymeric network (IPN) hydrogels are obtained. Due to the homogeneous distribution of g-C3N4 and the existence of thermoresponsive polymers, the hybrid IPN hydrogels present good adsorption capability and high degradation efficiency for methylene blue (MB) especially at high temperature under ultraviolet radiation. Based on this unique property, the bracelet monitoring skin health is prepared by simply immersing the hybrid IPN hydrogels into the MB solution and then wrapping it with PET foil. Because the immersion time for the top, middle, and bottom parts of the hybrid IPN hydrogels is gradually increased, their colors vary from light to dark blue. A longer time is required for the discoloration of the darker part under solar ultraviolet radiation. Thus, the bracelet can be used to conveniently monitor the dose of solar ultraviolet radiation by simply checking the discoloration in the bracelet under sunshine. Due to the facile preparation and low cost of the bracelet, it is a promising candidate for wearable devices for skin health management.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 81927-55-1, you can contact me at any time and look forward to more communication. SDS of cas: 81927-55-1.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 694-80-4, Name is 1-Bromo-2-chlorobenzene, SMILES is C1=CC=CC(=C1Cl)Br, in an article , author is Rautio, Timo, once mentioned of 694-80-4, Product Details of 694-80-4.

A silver shell-copper core coating was applied on additively manufactured (AM) AlSi10Mg alloy to improve the electrical conductivity, corrosion resistance, surface roughness and indentation hardness. Surface microstructure evolution and roughness of the AM alloy, i.e. as-built, during the subsequent processes, such as heat treatment, shot peening and Ag-Cu coating, were comprehensively characterized using secondary electron imaging in a scanning electron microscope and a scanning laser microscope, respectively. Also, the surface indentation hardness of the coated alloy was evaluated to study the mechanical response. The corrosion behavior and electrical conductivity of the Ag-Cu coated AM alloy were evaluated and compared with the as-built and shot peened AM alloy using the electrochemical and the electrical resistivity measurements, respectively. The results showed that the Ag-Cu coating could significantly increase the surface hardness of the AM AlSi10Mg four times along with an average of 60% improvement in roughness. The electrochemical characterization shows a significant increase in the corrosion resistance for the Ag-Cu coated AM AlSi10Mg with a low corrosion current density of 4 mu mA/cm(2) in a chloride solution compared to the uncoated alloy. Finally, it was observed that the Ag-Cu coating leads to reduction of the electrical resistance of the studied AM alloy by 40%. Consequently, the electrical conductivity property of the coated AM AlSi10Mg increases.
