Summary: We constructed amorphous bimetal Ni-Fe borides as efficient catalysts for the hydrogenolysis of biomass-derived 5-hydroxymethylfurfural (HMF) into 2,5-dimethylfuran (DMF), a potential biofuel candidate. The Ni(1.52Fe0.36)BOx catalyst achieved a near-quantitative DMF yield under mild operating conditions, with an excellent DMF formation rate that is significantly higher than state-of-the-art nickel-based catalysts. Mechanistic investigations revealed that the presence of Fe contributed to the generation of electron-enriched metal sites and powerful acidic sites, promoting the hydrogen activation and cleavage of C-O bond. The Ni(1.52Fe0.36)BOx catalyst also showed good recyclability and universality in the hydrogenolysis of various biomass-derived unsaturated aldehydes.

Summary: A molecular dynamics simulation study was conducted to investigate the relationship between cluster correlation index and nanoclusters during rapid solidification of FexNi(100-x)(40 <= x <= 80) amorphous alloys. It was found that the correlation between clusters affects the formation of nanoclusters, with Fe-rich alloys more likely to form large-sized nanoclusters.

Summary: Understanding the synergistic mechanisms of bimetal single atom catalysts is crucial for designing and synthesizing effective catalytic materials. This study presents a novel bimetal of Fe and Ni anchored carbon nitride (CN-FeNi-P) and reveals the importance of synergistic effects. Experimental results show that CN-FeNi-P, with uniformly distributed Fe/Ni-N4P2 coordination sites, forms a Fe-P-Ni structure at the second shell via P bridging. The Fe-dominated active sites in CN-FeNi-P, resulting from the interaction between Fe and Ni single atoms, enable high efficiency electron utilization, leading to 100% enoxacin degradation and rare defluorination rate.

Summary: In this study, a new type of amorphous chiral tartaric acid-FeNi coordination polymer was fabricated by electrodeposition methods, showing both high spin-polarization and high electrocatalytic activity for oxygen evolution. Circular dichroism measurements revealed the optical activity of the coordination polymer. Conductive atomic force microscopy measurements demonstrated the high spin polarization of the chiral electrocatalyst, which effectively reduced the formation of hydrogen peroxide byproducts compared to achiral ones. These chiral Fe-Ni electrocatalysts exhibited a low overpotential of 205 and 280 mV to achieve 10 and 100 mA cm(-2), respectively.

Summary: The study investigates low-temperature electrical and thermal conductivity of CoSi and Co1-xMxSi alloys. Unexpectedly, Fe- and Ni-containing alloys exhibit higher thermal conductivity at temperatures below 20 K, possibly due to phonon scattering by charge carriers. A theoretical model considering the complex semimetallic electronic structure of CoSi explains the thermal conductivity behavior in Co1-xFexSi alloys below 20 K.

Summary: Researchers have developed a bottom-up method for synthesizing rocksalt high-entropy oxides (HEOs) containing Mn and Fe. They investigated the crystal structure and random cation-site occupancy of FeO-HEO, showing improved structural robustness and the viability of an oxygen sublattice as a buffer layer. Compositional analysis revealed the valence and spin state of the iron species, and the antiferromagnetic order of FeO-HEO below a transition temperature around 218 K was reported, along with predictions for the phase stability conditions of Mn and Fe-containing HEOs.

Summary: Amorphous brazing foils are increasingly used due to their flexibility and ease of application. Research is needed to substitute nickel with iron in conventional nickel-based brazing foils, and thermodynamic databases can be used for prediction. The foils are produced using the melt-spin process and characterized using DSC and SEM. Novel iron-based brazing foils with different compositions have been successfully produced and characterized as partly amorphous or nanocrystalline structure.

Summary: Designing S-Scheme heterojunctions can effectively improve the photocatalytic performance for hydrogen evolution by avoiding futile charge transport routes. In this study, a twin S-Scheme heterojunction consisting of graphitic C3N4 nanosheets, hydrogen-doped rutile TiO2 nanorods, and anatase TiO2 nanoparticles was proposed. The catalyst exhibited a high hydrogen evolution rate of 62.37 mmol g(-1) h(-1) and an apparent quantum efficiency of 45.9% at 365 nm. The significant enhancement of photocatalytic performance was attributed to the efficient charge separation and transfer facilitated by the unique twin S-Scheme structure. In situ X-ray photoelectron spectroscopy (XPS), electron spin resonance (ESR) spin-trapping tests, and other characterizations confirmed the charge transfer route in the twin S-Scheme.

Summary: A series of LaNi1-xFexO3/g-C3N4 heterojunction photocatalysts were prepared by a simple wet chemical method and their structural, morphological, optical, electrochemical properties, as well as their photocatalytic degradation performance for tetracycline and Cr(VI), were investigated. The LaNi0.8Fe0.2O3/g-C3N4 composite photocatalysts exhibited excellent photocatalytic performance due to the synergy of doping and constructing heterojunctions. Doping of Fe ions increased the concentration of oxygen vacancies, favoring the formation of electron traps, while the type-II heterojunction formed between LaNi0.8Fe0.2O3 and g-C3N4 effectively enhanced the separation and transfer of photoinduced carriers, thereby promoting photocatalytic activity. The LaNi0.8Fe0.2O3/g-C3N4 photocatalyst showed long-term stability after three cycles of use, and a photocatalytic mechanism was proposed.

Summary: High-entropy perovskite oxides (HEPOs) have unstable energy storage in high-power battery-supercapacitor hybrid devices. This study reveals the dual-ion energy storage mechanism of La0.7Bi0.3Mn0.4Fe0.3Cu0.3O3 nano-HEPO in aqueous alkaline BSH devices. The deintercalation of hydrogen cations is hindered during discharge due to surface filling with oxygen vacancies, causing irreversible phase transition and capacity deterioration.
