Abstract Exploring and comprehending magnetocaloric materials with spin reorientation (SR) phase transition is of vital importance for practical applications effect (MCE). Herein, this study presents a systematic on the magnetic properties, heat transport structure, electronic structure NdNi compound. observed to undergo an SR ferromagnetic (FM) paramagnetic (PM) successively increasing temperature. Neutron powder diffraction (NPD) experiment reveals that involves rotation Nd moment from...
Although there are many studies on the preparation and electrochemical properties of different crystal forms manganese dioxide, few their by a liquid phase method influence physical chemical performance. In this paper, five dioxide were prepared using sulfate as source difference was studied morphology, specific surface area, pore size, volume, particle size structure. The electrode materials, capacitance composition obtained performing CV EIS in three-electrode system, introducing kinetic...
Manganese has excellent performance in removing metal ions from aqueous solutions, but there are few studies on the adsorption and removal of heavy impurities salt solutions. In this paper, cobalt nickel MnSO4 solution by δ-MnO2 prepared two different manganese sources was studied. The optimum conditions were as follows: When concentration Mn2+ 20 g/L, addition 10 Co2+ 80 mg/L, Ni2+ reaction time 60 min, temperature °C, pH value 7, rate reached more than 80%. dioxide adsorbed metals analyzed...
Cystatin C (CysC) has been proven to be used diagnose acute kidney injury (AKI) rapidly and sensitively early. Therefore, it is urgent develop a sensitive, novel, rapid method for detecting CysC. In this work, novel photoelectrochemical (PEC) biosensor was designed ultrasensitive CysC detection. Ti-MOF@DM-LZU1@Au as photosensitive material first modified on the ITO electrode surface. Then, Ab
Three different crystalline forms of Mn3O4 were successfully prepared by a liquid phase method with additives. Using XRD, SEM, EDS, BET, compacted density and electrochemical analysis, the effects additives on morphology, composition, surface characteristics, specific area, other physical chemical properties manganese oxides investigated. The results showed that rod type was mixing ammonia water anhydrous ethanol in 1 : ratio an appropriate amount cetylmethyl ammonium bromide as additive....
The effect of Ge substitution for Ga atoms on the magnetic properties and MCE resulting Pr(Ga,Ge) compounds was systematically investigated by combined measurements neutron powder diffraction (NPD) experiments. Two transitions were identified PrGa0.9Ge0.1 from ferromagnetic (FM) to FM at Tt = 26 K paramagnetic (PM) TC 56 K. PrGa0.8Ge0.2 shows similar with 55 75 Diffraction experiments confirmed that distance between nearest neighboring Pr decreases increasing content, which would lead an...
In the work, polycrystalline PrNi compound was synthesized by arc-melting method. The crystal structure is determined as a CrB-type orthorhombic (Space group Pnma).
