As renewable energy source integration increases, P2G technology that can store surplus power as methane is expected to expand. The development of a CO2 methanation catalyst, one the core processes concept, being actively conducted. In this work, low-rank coal (LRC) was used catalyst support for methanation, it potentially enhance diffusion and adsorption behavior by easily controlling pore str...

Ni-doped TaSi2 nanowires were synthesized by annealing NiSi2 film as the mediated layer in a Ta reductive ambient at 950 ◦C for 16 h. The hysteresis loop has a hard magnetization axis and high remanence with a coercive force of 120 Oe when the applied magnetic field is perpendicular to the substrate (parallel to the nanowires) and the hysteresis loop has an easy magnetization axis and low reman...

The temperature and fresuency dependence of tg8 and E' for Nk ~Ztb ferrites was studied in the 10'lo6 Hz frequency range and 20-200°C temperrhrre tange. The experimental curves exhibit aspects very dependent of composition. To verify Ulat interfacial losses, expected to appear in this type of system are compatible with the experimental results a calculation of the dielectric permittivity and di...

The novel nickelate superconductors of infinite-layer type feature challenging electronic pecularities in the normal-state phase diagram with doping. Distinct many-body behavior and different dispersion regimes entangled $\{$Ni-$d_{z^2}$, Ni-$d_{x^2-y^2}$$\}$ orbital sector give rise to highly rich physics, which is here studied for case NdNiO$_2$ system. An analysis based on advanced realistic...

The effect of Ni doping (1%, 2%, and 5%) on vanadium phosphate catalysts prepared via VOPO4·2H2O was described and discussed. At low levels, the Ni dopant significantly enhanced the amount of the active lattice oxygen species O− and lowered the reduction peak temperature corresponding to the reduction of V5+ and V4+ phases. A combination of powder X-ray diffraction, temperature-programmed reduc...

The search for above room temperature ferromagnetism in dilute magnetic semiconductors has been intense in recent year. Arrays of perpendicular ferromagnetic nanowire/rods have recently attracted considerable interest for their potential use in many areas of advanced nanotechnology. We report a simple low-temperature chemical vapor deposition (CVD) to create self-assembled comb-like Ni-/undoped...

This current study reports preparation of Nickel-Gadolinium doped Ceria (Ni-GDC) composite via controlled unidirectional freeze casting of aqueous-based GDC slurry completed with nickel infiltrated into the porous GDC samples. Gadolinium doped ceria powder prepared by gel-combustion synthesis method. The oxide powder was confirmed to be the fluorite-structured of Ce0.8Gd0.2O1.9 solid solution b...

MWCNTs composite with UiO-66-NH 2 MOF doped Ni( ii ) ions produced a highly efficient heterogeneous electrocatalyst for the water oxidation reaction.
