Ni2B@Cu2O and Ni2B@CuCl2 are introduced as simple and efficient earth-abundant transition-metal-based nanocomposites for thegreen one-pot reductive acetylation of aromatic nitro compounds and direct N-acetylation of arylamines using a solvent-free mechanochemical grinding technique. The designed Ni2B-based nanocomposites were characterized by Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM) with energy-dispersive X-ray (EDX) spectroscopy. Notable advantages of these methods include broad substrate scope, use of a solvent-free mechanochemical grinding technique, implementation of earth-abundant transition-metal-based nanocomposites as simple and practical catalysts, and short reaction time and high yield at ambient condition. The mentioned methods can also be successfully applied for thesynthesis of a broad range of other amides (especially substituted acetamides) using green chemistry protocols. Also, the recoverability and reusability of the mentioned new nanocomposites were investigated. [GRAPHICS] .

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3144-09-0, in my other articles.

BACKGROUNDAquatic source gelatins are gaining more attention due to the advantages in safety and religion acceptability compared with mammalian sources. For understanding the effects of extracting temperature on gelatins from chum salmon (Oncorhynchus keta) skins (GCSS), gelatins were extracted at temperatures from 40 to 90 degrees C and the physiochemical properties of GCSS were investigated. RESULTSGCSS yield increased while imino acids content declined as the increase of temperature. GCSS40, 50 and 60 showed strong -, 1- and 2-chains but the three faded in GCSS70, 80 and 90, with the presence of low molecular weight fragments. Amides A, I and III were shifted to higher wavenumber in GCSS70, 80 and 90 compared with that of GCSS40, 50 and 60. X-ray diffraction showed lower intensity of peak at 7 degrees in GCSS80 and 90 than in the other GCSS. Gel strength declined while a*, b* and E* value increased as temperature increased. Foam expansion and stability of GCSS40, 50 and 60 were lower than those of GCSS70, 80 and 90. Emulsion activity and stability decreased as temperature increased. CONCLUSIONExtracting temperature greatly affected yield, molecular composition and functionalities of GCSS. A temperature lower than 50 degrees C is recommended for GCSS extraction.

Multidimensional magic-angle spinning solid-state NMR experiments are described that permit cis and trans peptide bonds in uniformly C-13,N-15-labeled peptides and proteins to be unambiguously distinguished in residue-specific manner by determining the relative orientations of the amide C-13′ CSA and H-1-N-15 dipolar coupling tensors. The experiments are demonstrated for model peptides glycylglycine and 2,5-diketopiperazine containing trans and cis peptide bonds, respectively. Subsequently, the measurements are extended to two representative proteins that contain exclusively trans peptide bonds, microcrystalline B3 immunoglobulin domain of protein G and Y145Stop human priori protein amyloid fibrils, to illustrate their applicability to a wide range of protein systems.

In this study, new tri-amides 5a-1 have been synthesized via a one-pot four-component Ugi reaction between repaglinide, aniline derivatives, aldehyde derivatives, and cyclohexyl isocyanide in good yields. These compounds were evaluated against yeast alpha-glucosidase. Obtained in vitro alpha-glucosidase results demonstrated that all the synthesized compounds 5a-1 were more potent than standard inhibitor acarbose. Among them, the most potent compounds were compounds 5j, 5k, and 5h. The kinetic analysis of the most potent compound 5j revealed that this compound is a competitive inhibitor for alpha-glucosidase (K-i = 24 mu M). Furthermore, docking study of the most potent compounds was also performed in the alpha-glucosidase active site to find interaction modes and binding energies of these compounds.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 62-57-7, Name is H-Aib-OH, molecular formula is C4H9NO2, belongs to amides-buliding-blocks compound, is a common compound.

The thermodynamics of complex formation of Ni2+ with molecular liquids (ML), dimethyl sulfoxide (DMSO), methanol (MeOH), and acetonitrile (AN) in the ionic liquid (IL) of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([C(2)mim][TFSA]) has been elucidated using ultraviolet (UV)-visible spectroscopy. X-ray structural analyses for single crystals grown from Ni2+-[C(2)mim][TFSA]-DMSO and -AN solutions at high ML contents have shown that six DMSO oxygen or AN nitrogen atoms coordinate with Ni2+ to form octahedral structures of [Ni(dmso)(6)](TFSA)(2) and [Ni(an)(6)](TFSA)(2), respectively. This is the same in the case of the Co2+ complex of [Co(dmso)(6)](TFSA)(2). UV-visible spectroscopic experiments have revealed that the TFSA(-) anions that initially combine with Ni2+ in the IL are replaced with ML molecules in the IL-ML systems in three steps with increasing ML content. The electron donicities of the three MLs are larger in the order of DMSO > MeOH > AN. However, the stability of each complex does not simply depend on this order; the stability is higher in the order of [Ni(dmso)(n)] > [Ni(an)(n)](4) [Ni(meoh)(n)]. In other words, the stability of the MeOH complexes is lower than that of the AN ones, despite the higher electron donicity of MeOH. The reasons for the order of the complex stabilities have been interpreted on the molecular scale, according to the stepwise enthalpies Lambda H-n(0) and entropies T Lambda S-0(n) determined, together with the strength of the hydrogen bonding between the MLs and the imidazolium ring and the formation of MeOH clusters in [C(2)mim][TFSA].

Thermal degradation under wet conditions is considered as an important aging mechanism in polyamide 6,6 (PA 6,6). The effect of water on thermal degradation of amorphous PA 6,6 is investigated at relatively low temperatures, varying from 1000 to 2000 K, using reactive force field molecular dynamics (MD) and collective variable-driven hyperdynamics simulations. The simulation of the related long-term chemical reactions is made possible thanks to the self-learning accelerated MD concept of hyperdynamics in combination with the corresponding accurate reproduction of the correct dynamics, consistent with unbiased MD simulations. The kinetics of cleavage reactions of the amide bonds in the backbone of the polymer chains, responsible for the thermal degradation of the polymer, is studied, and the influence of water content on the activation energy and pre-exponential factor of the cleavage reactions is explored. The results show that activation energy and pre-exponential factor are in agreement with experimental data. The proposed simulation framework not only estimates kinetic properties of thermal degradation that are consistent with experimental observations but also provides a predictive tool for studying long-term thermal degradation of PA 6,6.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 6582-52-1. Name: 2,2′-Methylenedianiline.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 15761-38-3, Name is Boc-Ala-OH, SMILES is C[C@H](NC(OC(C)(C)C)=O)C(O)=O, belongs to amides-buliding-blocks compound. In a document, author is Vigorito, Annalisa, introduce the new discover, Category: amides-buliding-blocks.

Thin films with (nano)fibrillar morphologies were successfully obtained in fully-biobased poly(butylene succinate-co-adipate)/poly(amide-11) blends (PBSA/PA11, 85/15 wt/wt) using an extrusion-blowing process. Impacts of PA11 grade and take-up ratio on the morphology of PBSA/PA11 were particularly highlighted. Scanning electron microscopy analyses indicated that PA11 with high melt volume-flow rates are beneficial to the development of (nano)fibrillar morphologies in PBSA/PA11 blown film. On the contrary, unstable film blowing processing without fibrillar morphologies was attested for PA11 with low melt volume-flow rates. Increasing the take-up ratio during extrusion-blowing of PBSA/PA11 clearly generates finer PA11 (nano)fibrils into PBSA. Fibril diameters down to 300 nm could be reached with an optimal PA11 grade promoting enhanced mechanical properties (higher ductility and toughness). The formation of stable PA11 (nano)fibrils into PBSA is discussed via rheological assessments of viscosity/elasticity ratio. A specific attention was finally paid to the PBSA strain-hardening behavior in PBSA/PA11 using elongational rheological tests. PA11 (nano)fibrillation helps maintaining the strong PBSA strain-hardening and thus play a major role on the processability of PBSA/PA11 blends by extrusion blowing. As a conclusion, the PA11 grade represents a crucial parameter to control the production of PBSA/PA11 blown films with refined (nano)fibrillar structures and enhanced physico-chemical properties.

Synthetic Route of 62009-47-6, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 62009-47-6, Name is 2-Aminomalonamide, SMILES is O=C(C(C(N)=O)N)N, belongs to amides-buliding-blocks compound.

For the synthesis of the ferric bistrimethylsilylamido complex [Fe{N(SiMe3)(3)}(3)] literature gives differing synthetic protocols based on crystallization from solution. In this report we present a ‘solvent-free’ structural phase of [Fe{N(SiMe3)(3)}(3)] which was obtained by sublimation of the product obtained from the reaction of 2 eq FeCl3 with 3 eq LiN(SiMe3)(2) in benzene. It could be characterized by single crystal as well as powder XRD and elemental analysis. However, Fe-57 Mossbauer spectroscopy suggests a contamination of the main product with an Fe(II) species. Also, a part of the solid reaction byproducts from the reactions in solution were identified by powder XRD and Li-7 MAS NMR which indicate distinct redox side reactions between oxidizing FeCl3 and reducing LiN(SiMe3)(2), a fact which rationalizes the lower than expected yields and the observation of an Fe(II) impurity compound. AC magnetic measurements of [Fe{N(SiMe3)(3)}(3)] have been performed in an extended frequency range up to 10(4) s(-1), allowing for a more precise evaluation of the magnetic relaxation parameters when compared to previously published measurements.

In a document, author is Li, Yiming.

The recombinant polyhistidine-tagged hemoglobin I ((His)(6)-rHbI) from the bivalve Lucina pectinata is an ideal biocomponent for a hydrogen sulfide (H2S) biosensor due to its high affinity for H2S. In this work, we immobilized (His)(6)-rHbI over a surface modified with gold nanoparticles functionalized with 3-mercaptopropionic acid complexed with nickel ion. The attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) analysis of the modified-gold electrode displays amide I and amide II bands characteristic of a primarily alpha-helix structure verifying the presence of (His)(6)-rHbI on the electrode surface. Also, X-ray photoelectron spectroscopy (XPS) results show a new peak after protein interaction corresponding to nitrogen and a calculated overlayer thickness of 5.3 nm. The functionality of the immobilized hemoprotein was established by direct current potential amperometry, using H2S as the analyte, validating its activity after immobilization. The current response to H2S concentrations was monitored over time giving a linear relationship from 30 to 700 nM with a corresponding sensitivity of 3.22 x 10(-3) nA/nM. These results confirm that the analyzed gold nanostructured platform provides an efficient and strong link for polyhistidine-tag protein immobilization over gold and glassy carbon surfaces for a future biosensors development.

This work deals with evaluating the role of starch derivatives on enhancing the performance of carbon xerogels (XACs), as HCHO-scavenger in producing environmentally friendly urea-formaldehyde (UF)- agro-based composites. In this respect, polyvinyl alcohol and amide modified starch (PVA-ST and AM-ST) were used. The XACs examined in hybrid scavengers were prepared from different aldehydes-based xerogels; while the substrates used for production of Agro-composites were rice straw (RS) and sugar cane bagasse (SCB). The results showed that, the hybrid scavenger led to increase the thermal stability of UF, as well as it provided acceptable UF adhesive system for producing environmental performance and highest strength agro-composites. Where, it produced bagasse composite with static bending properties 27.2 MPa MOR, 5734 MPa MOE and 0.87 MPa IB. The static bending values exceeded the requirements for class H-3 (ANSI Standard). The corresponding free formaldehyde value was reached to 9.5 mg/100 gin sample (reduction 66.7%).
