Capacity fading mechanism of tin phosphide anodes in sodium-ion batteries
Tin phosphide (Sn4P3) is here investigated as an anode material in half-cell, symmetrical, and full-cell sodium-ion batteries. Results from the half-cells using two different electrolyte salts of that sodium bis(fluorosulfonyl)imide (NaFSI) or sodium hexafluorophosphate (NaPF6) show that NaFSI provi...

Increasing the ion-exchange capacity of MFI zeolites by introducing Zn to the aluminosilicate frameworks
MFI Zeolites exchanged with various cations have gained a great deal of attention as catalysts. Increase in the ion-exchange capacity of zeolites can improve their catalytic properties by introducing more active sites; however, the ion-exchange capacity of MFI zeolites is limited by maximum aluminum...

Iron(II) complexes of tris(2-pyridylmethyl)amine (TPMA) and neutral bidentate ligands showing thermal- and photo-induced spin crossover
Three new mononuclear Fe(ii) complexes have been prepared and characterized by the combination of tetradentate tris(2-pyridylmethyl)amine (TPMA) with three neutral bidentate ligands, such as ethylenediamine (en), 1,2-diaminopropane (pn) and 2-picolylamine (2-pic), in compounds [FeII(TPMA)(en)](ClO4)...

DFT Investigation on the Adsorption of Munition Compounds on [small alpha]-Fe2O3: Similarity and Differences with [small alpha]-Al2O3
Arid environments have long been a testing and training ground for novel munitions. However, these activities leave behind unknown quantities of munition residues with unknown impact on local flora and fauna. In particular, arid soil contains Lewis acidic metal oxides which bind and catalyze the ele...

Transpeptidation-Directed Intramolecular Bipartite Tetracysteine Display for Sortase Activity Assay
We developed a label-free method to measure Sortase activity by using transpeptidation-directed intramolecular bipartite tetracysteine display. This assay is homogenous with a detection limit of 10.7 ng/mL, and it can be applied to characterize the Sortase A (SrtA)-targeted inhibitor, providing a ne...

Development of Trapezoidal MgO Catalyst for High-Efficient Transesterification of Glycerol and Dimethyl Carbonate
A series of micro-sized MgO with various morphologies have been prepared by varying the reaction temperature and stirring time during precipitation, and were investigated for the production of glycerol carbonate from the transesterification of glycerol with dimethyl carbonate. In contrast to other m...

Rhodium-catalyzed oxidative CH/CH cross-coupling of aniline with heteroarene: N-nitroso group enabled mild conditions
The development of transition metal-catalyzed oxidative C–H/C–H cross-coupling between two (hetero)arenes to forge aryl-heteroaryl motifs under mild conditions is an appealing yet challenging task. Herein, we disclose a rhodium-catalyzed oxidative C–H/C–H cross-coupling reaction of an N-nitrosoanili...

Dissociative electron attachment induced ring opening in five-membered heterocyclic compounds
Five-membered heterocyclic structures, which exist widely in biological systems and play an active role in various biochemical processes, have been studied extensively from a fundamental perspective. Here, the fragmentation patterns of isoxazole, a representative five-membered heterocycle, upon diss...

A[small beta] under stress: the effects of acidosis, Cu2+-binding, and oxidation on amyloid [small beta]-peptide dimers
In light of the high affinity of Cu2+ for Alzheimer's Aβ1–42 and its ability to subsequently catalyze the formation of radicals, we examine the effects of Cu2+ binding, Aβ oxidation, and an acidic environment on the conformational dynamics of the smallest Aβ1–42 oligomer, the Aβ1–42 dimer. Transitio...

An efficient t-BuOK promoted C3-chalcogenylation of indoles with dichalcogenides
A versatile and efficient method for the synthesis of 3-chalcogenyl-indoles from indoles and dichalcogenides employing t-BuOK as a promoter at room temperature has been achieved. The present protocol exhibited a broad functional group tolerance. Diverse 3-sulfenyl- and 3-selenyl-indoles were rapidly...

Spontaneous domain formation in disordered copolymers as a mechanism for chromosome structuring
Motivated by the problem of domain formation in chromosomes, we studied a co--polymer model where only a subset of the monomers feel attractive interactions. These monomers are displaced randomly from a regularly-spaced pattern, thus introducing some quenched disorder in the system. Previous work ha...

The proportion of Met80-sulfoxide dictates peroxidase activity of human cytochrome c
The peroxidase activity of cytochrome c is proposed to contribute to apoptosis by peroxidation of cardiolipin in the mitochondrial inner membrane. However, cytochrome c heme is hexa-coordinate with a methionine (Met80) on the distal side, stopping it from acting as an efficient peroxidase. The first...

Insertion of CS2 into the Mg-H bond: synthesis and structural characterization of the magnesium dithioformate complex, [TismPriBenz]Mg([small kappa]2-S2CH)
The tris[(1-isopropylbenzimidazol-2-yl)dimethylsilyl]methyl magnesium hydride compound, [TismPriBenz]MgH, undergoes insertion of CS2 into the Mg–H bond at room temperature to give [TismPriBenz]Mg(κ2-S2CH), the first structurally characterized magnesium dithioformate compound. The dithioformate compl...

Investigation on photoluminescence properties, Judd-Ofelt analysis, luminescence nanothermometry and optical heating behaviour of Er3+/Eu3+/Yb3+: NaZnPO4 nanophosphors
Er3+/Eu3+/Yb3+: NaZnPO4 nanophosphors synthesized by co-precipitation technique have been structurally and optically characterized. The effect of Eu3+ ion concentration on photoluminescence (PL) emission intensity and the energy transfer mechanisms implicated in the present nanophosphors has been di...

Molecular motions in a fluxional ([small eta]6-indenyl)tricarbonylchromium hemichelate: a density functional theory molecular dynamics study
A comprehensive Density Functional Theory (DFT) study is reported on molecular motions occurring in a hemichelate complex, formally composed of the (η3-2-methylallyl)Pd(ii) cation bonded to a (η6-indenyl)tricarbonylchromium anion, that has been recognized as being highly fluxional in a previous expe...
