Environmentally Friendly and Recyclable Natural-Mediator-Modified Magnetic Nanoparticles for Laccase-Catalyzed Decolorization

The high cost, potential toxicity, and possible enzyme inhibition ability of artificial mediators have limited the large-scale application of laccase (Lac)/mediator systems. Here, sinapic acid (SA), a natural mediator, was covalently attached to amino-functionalized magnetic nanoparticles (MNPs) via amide bond formation. The as-prepared SA@MNPs were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, cyclic voltammetry, and thermogravimetric analysis. The SA@MNPs were then applied to evaluate the activity of the immobilized mediator for Lac-catalyzed dye decolorization using indigo carmine (IC) as a model dye. When SA and SA@MNPs were used as Lac mediators, IC decolorization yields of similar to 93% and 96%, respectively, were obtained after 60 min. Moreover, SA@MNPs exhibited an IC decolorization yield of similar to 90% after being reused for 8 cycles. The Lac/SA@MNP system was shown to degrade IC by breaking down the chromophoric group. The easy recyclability, good reusability, nontoxicity, and relatively low cost of SA@MNPs make this immobilized natural mediator a promising tool for dye treatment.

Influence of amine functionalized graphene oxide on mechanical and thermal properties of epoxy matrix composites

A new approach for synthesized amine functionalized graphene oxide (AFGO) was used by diethylenetriamine as a reducing or functionalizing agent. The purpose of this work is to determine the effect of AFGO on the mechanical and thermal properties of epoxy nanocomposites. In addition, the optimization of various weight percentages of AFGO was carried out. Physical and chemical characterizations were also reported to determine the effects of AFGO. The structure and morphology of the AFGO nanosheets were confirmed by fourier transform infrared spectroscopy, energy dispersive spectroscopy, X-ray diffraction analysis, and field emission scanning electron microscopy. Successful formation of amide bonds through graphene oxide (GO) sheet functionalization was proved by characterizations. Solution blending, as a simple method, was used for composite formation. The mechanical and thermal properties of the epoxy/AFGO composites were assessed. There was increment in tensile strength by 67%, flexural strength by 51%, and impact strength by 152% at 0.3 wt% loading of AFGO in epoxy composites. Similarly, the increment in hardness was also observed from 0.1 to 0.3 wt% of AFGO loading. The glass transition temperature of epoxy/AFGO nanocomposites effectively improved from 88.4 to 97.3 degrees C. The thermal stability of epoxy/AFGO nanocomposite increased from 351 to 358 degrees C.

Infrared spectroscopic and computational studies of Co(ClO4)(2) dissolved in N,N-dimethylformamide (DMF). Vibrations of DMF influenced by Co2+ or ClO4- or both

Infrared (IR) spectroscopy for N,N-dimethylformamide (DMF) shows that the OCN bend (SOCN) and the CO stretch (vCO) vibrations undergo an upshift and a downshift, respectively, on the dissolution of Co(ClO4)(2). Quantum chemical calculations are performed for optimizing the structures and predicting the IR spectra of model complexes for solute species. The calculations reveal that Co2+ exerts a much larger influence than ClO4- on the vibrations of DMF. For Co2+(DMF)(6), in which each DMF molecule is coordinated to Co2+ via the O atom, the Co2+ DMF interaction upshifts the SOCN frequencies (+24 cm(-1) on average) while the dipole coupling gives rise to splitting (12 cm(-1)) of the modes. On the other hand, the Co2+ . . . DMF interaction downshifts the vCO frequencies (-15 cm(-1) on average) while the splitting of the modes amounts to 37 cm(-1). As a result, one of the vCO modes is located at an upshifted position (+13 cm(-1)) despite the O-atom coordination. For six-coordinated isomers of Co2+(DMF)(7), the SOCN and vCO frequencies of the second-sphere DMF are close to those of bulk DMF in neat liquid. The calculations indicate that it is difficult to prove or exclude the formation of contact ion pairs [Co(DMF)(5)ClO4](+) and solvent-shared ion pairs [Co(DMF)(6)ClO4](+) by IR spectroscopy in the SOCN and vCO regions. However, asymmetric ClO stretches of the ClO4- moiety suggest that conceivable is the coexistence of solvent-shared ion pairs only. (C) 2020 Elsevier B.V. All rights reserved.

Insight into nucleophilic fragmentation mechanisms by glutamic acid side chain in singly protonated glutathione and related peptidyl ions

Fragmentation mechanisms of the singly protonated glutathione (gamma-ECG) and its synthetic analogue peptides (ECG and PPECG) have been investigated by liquid chromatography tandem-mass spectrometry and theoretical calculations. In the mass spectra, similar fragmentation patterns were observed for gamma-ECG and ECG, but a completely different one was found in the case of PPECG. The E-C amide bond cleavage is the predominant pathway for the fragmentation of gamma-ECG and ECG, whereas the additional N-terminal prolyl residues in PPECG significantly suppress the E-C amide bond cleavage. Theoretical calculations reveal that the fragmentation efficiencies of the E-C bonds in the protonated gamma-ECG and ECG are much higher than that in the protonated PPECG, being attributed to their lower barriers of the potential energy; clearly the introduction of two prolyl residues can increase substantially the potential energy barrier. In the proposed mechanism, the protonated E-C amide bonds in the three peptides are first weakened followed by a nucleophilic addition by the glutamyl carboxyl oxygen atom in side chain, leading to the breaking of the E-C amide bonds. However, the processes of E-C bond fragmentation for three protonated analogs were not collaborative. Protonated amide bonds first fragment, then the nucleophilic addition by the side chain of glutamyl carboxyl oxygen atom takes places. On the other hand, the prolyl residues in PPECG can largely diminish the nucleophilic addition, resulting in a much lower efficiency of its E-C amide bond breaking. Distance analysis indicates that breaking the E-C amide bonds in the protonated gamma-ECG, ECG, and PPECG ions could not occur without the assistance from the nucleophilic attack, highlighting an asynchronous collaborative process in the bond breakings.

Dual Interphase Layers In Situ Formed on a Manganese-Based Oxide Cathode Enable Stable Potassium Storage

Mn-based oxides have attracted extensive attention as electrode materials. However, the irreversible phase transition and Mn2+ dissolution result in their structure instability and performance decay. Here, we report dual interphase layers in situ formed on P2-K0.67MnO2 (P2-KMO) in 6.0 M of potassium bis(fluorosulfonyl)amide in diglyme (KFSI/G2) during charging. It is composed of a solid-electrolyte interphase (SEI) and K-poor spinel interlayer on P2-KMO, which are derived from the simultaneous decomposition of 6.0 M KFSI/G2 and disproportionation of surface Mn3+ They cooperatively enable the reversible phase transition of P2 <-> P ” 2 in the bulk P2-KMO and mitigate Mn loss. This leads to a high capacity retention of 90.5% and a Coulombic efficiency of 100% after 300 cycles. The investigation highlights the significance of interphase chemistry of electrode materials for potassium-ion batteries and beyond.
