The development of effective oxygen electrode catalysts for renewable energy technologies such as metal-air batteries and fuel cells remains challenging. Here, we prepared a novel high-performance oxygen reduction reaction (ORR) catalyst comprised of Fe₂N nanoparticles (NPs) in situ decorated over an N-doped porous carbon derived from pomelo peel (i.e., Fe₂N/N-PPC). The decorated Fe₂N NPs provi...

This theorem will be used in both constructions, the one of a non-slender thin class, and the one of a slender thin class. The proof starts developing ideas the will be used in both of those constructions. In the case when [T ] is perfect, we will define two tree-embeddings f, r : 2 → S satisfying that for every σ ∈ 2, (fr1) f(σ) ⊆ r(σ), f(σ0) = r(σ)0, f(σ1) = r(σ)1, and (fr2) [Sf(σ)] = [Sr(σ)]...

We herein investigated the mechanisms underlying the contact leaching process in pyrite bioleaching by Acidithiobacillus ferrooxidans using scanning transmission X-ray microscopy (STXM)-based C and Fe near edge X-ray absorption fine structure (NEXAFS) analyses. The C NEXAFS analysis directly showed that attached A. ferrooxidans produces polysaccharide-abundant extracellular polymeric substances...

We have synthesized the octacyanoniobate-based cyano-bridged 3D ferromagnet {[Fe(II)(H(2)O)(2)](2)[Nb(IV)(CN)(8)].4H(2)O}(n) and characterized structurally, spectroscopically (XANES/EXAFS, IR, UV-Vis, Resonance Raman, (57)Fe Mössbauer spectroscopy) and magnetically. crystallizes in the tetragonal system, space group I4/m, a = 11.989(5) A, c = 13.237(5) A, V = 1902.6(13) A(3). 3D coordination ar...

A novel, versatile route to phosphorus- and carbon-substituted η(5)-phosphacyclohexadienyl complexes was developed. Reaction of the anionic 2,4,6-triphenylphosphinine iron complex [K([18]crown-6)(thf)2][Cp*Fe(PC5Ph3H2)] (1) with selected main group element electrophiles afforded the new complexes [Cp*Fe(2-endo-H-PC5Ph3H2)] (endo-3), [Cp*Fe(2-exo-H-PC5Ph3H2)] (exo-3), [Cp*Fe(1-Me-PC5Ph3H2)] (4),...

Three types of graphitic shelled-magnetic core (Fe, Fe/Co, and Co) nanoparticles (named as C-Fe, C-Fe/Co, and C-Co NPs) were synthesized by radio frequency-catalytic chemical vapor deposition (RF-cCVD). X-ray diffraction and X-ray photoelectron spectroscopy analysis revealed that the cores inside the carbon shells of these NPs were preserved in their metallic states. Fluorescence microscopy ima...

Through a variety of material screening experiments, Al was selected as the added metal and constituted a multiple micro-electrolysis system of Fe/C/Al. The metal proportion of alloy-structured filler was also analyzed with the best Fe/C/Al ratio of 3:1:1. The regular Fe/C/Al multiple micro-electrolysis fillers were prepared using a high-temperature anaerobic roasting method. The optimum condit...

this paper investigates the removal of iron and zinc from aqueous solution with dairy wastewaterin three different biomasses such as lactobacillus delbrueckii ssp bulgaricus (lb-12), streptococcus thermophillus(stm-7) and a combination of both this bacteria culture (yc-380) and the optimization of removal efficiencyusing minitab program. a full 23 factorial design of experiments was applied to ...

The title iron(III) compound, [Fe(C(12)H(21)N(2)Si)(2)Cl], is monomeric. The Fe atom is N,N'-chelated by the N-silylated anilide ligand. The two ligands around the Fe atom are arranged trans to each other. The Fe-N(amino) bond is longer than the Fe-N(anilide) bond by about 0.37 Å. The mol-ecule displays a pseudo-twofold rotation. The five-coordinate Fe atom demonstrates a highly distorted trigo...

Increased H2O2 production, indicating higher oxidative stress, and lower mitochondrial function was previously observed in duodenal mitochondria isolated from broilers with low feed efficiency (FE, gain:feed). Thus, experiments were conducted to 1) evaluate the activity of the respiratory chain complexes (complexes I to V) and 2) assess protein oxidation and mitochondrial protein expression in ...
