Copper-based catalysts, hallmarked by their ideal C–C coupling energy facilitated by the
symbiotic presence of Cu+ and Cu0 active sites, are poised to revolutionize the selective …

The characteristic size of the magnetocaloric materials in magnetic refrigerators,
thermomagnetic regenerators and energy harvesters is usually down to micrometer and …

In this work, the phase transitions of stoichiometric MnCoGe alloys were studied by
systematically varying the annealing conditions and applying hydrostatic pressure. First …

Ammonia is a potential carbon-free carrier for the on-site delivery of hydrogen and is critical
in the development of a hydrogen economy. Designing a noble metal-free catalyst for the …

This work investigates the magnetic properties and the magnetocaloric effect in the spin-1
Blume-Capel model. The study was carried out using the mean-field theory from the …

Two-dimensional (2D) vanadium disulfide (VS 2) can serve as a universal host for reversible
intercalation and deintercalation of alkali and alkaline earth metal ions. However, its …

As a family of rare-earth-free magnetocaloric materials, MnCoGe-based alloys have
attracted intensive attention in the past few years. In this study, we reveal that the deficiency …

In this study, the magnetic properties and the magnetocaloric effect of the spin-3/2 Blume–
Capel model were explored through the Mean Field Theory, developed through a variational …

In this work, a Ni-doped MnCoGe alloy has been synthesized by doping 4 wt% of Ni in place
of Ge. The room temperature XRD pattern shows that the alloy has crystallized in two …

The crystalline structure, magnetic properties, and magnetocaloric effect (MCE) of MnCo1− x
Cr x Ge (x= 0.01, 0.03, 0.05, 0.07) alloys have been investigated using x-ray powder …
