Abstract SmCo5 is one of the most promising candidates for achieving a hard magnet with a high coercivity. Usually, composition, morphology, and size determine the coercivity of a magnet, however, it is challenging to synthesize phase pure SmCo5 with

Recently, a large number of nanostructured metal-containing materials have been developed for the electrochemical CO2 reduction reaction (eCO2RR). However, it remains a challenge to achieve high activity and selectivity with respect to the metal load

The SmCo5 rare-earth hard magnet has the largest anisotropy field among all known magnetic materials, 32 MA m−1 (400 kOe), while the obtainable coercivity (Hc) is usually less than 30% of the anisotropy field. The coercivity is enhanced when the gr

Nano-sized particles of rutile TiO2 is a promising material for cheap high-capacity anodes for Li-ion batteries. It is well-known that rutile undergoes an irreversible order-disorder transition upon deep discharge. However, in the disordered state, t

A surge of interest has in recent years focused on the preparation of size-controlled permanent magnets through chemical routes. Herein, a sol-gel combustion assisted reduction-diffusion process is used to synthesize Sm–Co particles with sizes with
