Abstract The reversibility of the giant magnetocaloric effect (MCE) through magnetic field–induced magnetostructural transformation in Ni–Mn–In‐based alloys is a key issue towards potential refrigeration applications. In this work, Co and Cu are simultaneously doped to tune reversible properties associated with transformation. Owing integration large magnetization difference Δ M , suitable entropy S tr narrow thermal hysteresis T hys Ni 46 3 Mn 35 2 14 alloy, inverse martensitic realized...
Solid state refrigeration technology relies on the high-performance materials with remarkable caloric properties. Here, we demonstrate a large elastocaloric effect through stress-induced martensitic transformation in Heusler-type Co50V35Ga14Ni1 polycrystalline alloy. By rapidly removing moderate compressive stress of 400 MPa, adiabatic temperature change up to −12.1 K is achieved. Moreover, high cyclability more than 4000 loading/unloading cycles also obtained. With combination and good...
We demonstrate the temperature dependent elastocaloric effect in a Ni44.9Co4.9Mn36.9In13.3 polycrystalline alloy with strong ⟨001⟩A preferred orientation. It is found that adiabatic changes induced by compressive stress increase testing temperature. The giant change up to 14.7 K achieved on loading at 390 K, which much higher than around room Such enhanced attributed reduced magnetic contribution transformation entropy through narrowing interval between transition and martensitic controlled...
The development of low-cost adsorbent is an urgent need in the field wastewater treatment. In this study, sludge-based magnetic biochar (SMB) was prepared by pyrolysis sewage sludge and backwashing iron mud without any chemical agents. samples were characterized TGA, XRD, ICP, Organic element analysis, SEM, TEM, VSM BET. Characterization analysis indicated that substance SMB Fe3O4, saturation magnetization 25.60 emu·g-1, after adsorption experiment, could be separated from solution a magnet....
High-performance elastocaloric materials are highly sought in developing energy-efficient and environmentally friendly solid-state refrigeration. Here, we present an effective strategy to achieve a giant response by enlarging the lattice volume change ΔV/V0 upon martensitic transformation. Using Ni50Mn50 binary alloy as prototype, large transformation entropy ΔStr can be tailored vicinity of room temperature simultaneously doping Cu Ga. Especially, |ΔStr| values ⟨001⟩A-textured...
The ternary composite MgO@ZnO@BC was synthesized and characterized for the adsorption of Cu2+, Pb2+ heavy metal ions from wastewater. results show that addition in higher properties Cu2+ Pb2+, with a molar ratio 5% 0.1 g, maximum capacity (50.63 mg/g 61.46 Pb2+). Langmuir isotherm complex kinetics are secondary kinetics. mainly chemisorption, accompanied by physical adsorption. This method fully conforms to concepts clean production efficient waste utilization, providing reference removal...
Abstract A magnetically separable core–shell–shell nanosphere, Fe 3 O 4 @nSiO 2 ‐SO H@MS‐NHCOCH (n=nonporous, MS=microporous SiO ), was fabricated as an acid–base collaborative catalyst for the three‐component cyclization of aromatic aldehydes, nitroalkane, and sodium azide to afford 1 H ‐1,2,3‐triazoles. The bifunctional heterogeneous showed high activity this transformation good chemoselectivity, toxic HN not released during course reaction. variety aldehydes were transformed into...
