O presente artigo consiste em um estudo de revisão focado nos complexos metálicos de ródio (Rh), abrangendo os diferentes estados de oxidação possíveis (ródio(0), ródio(I), ródio(II) e ródio(III)), visando a uma provável aplicação de tais compostos de coordenação no combate ao câncer. O Ródio (Rh) é um elemento do grupo da platina (Pt) e um dos naturais candidatos à substituição do centro de coordenação platínico em complexos metálicos que atuem biologicamente de forma semelhante à cisplatina e seus compostos análogos e sucessores. Portanto, o objetivo do presente artigo é discutir, por meio d

In order to improve the interfacial wettability between Cu and β-SiC, electroless plating was employed to deposit a copper film on β-SiC particles. The β-SiC/Cu composites with different volume fraction ( from 30% to 60% ) were fabricated by hot-press sintering technique. The microstructures, bending strengths were investigated by SEM and a tensile machine. The results showed that the uniform and continuous Cu coating on the β-SiC particles can be obtained after electroless plating.

CNTs-Al matrix composites are considered to be promising heat dissipating materials because thermal conductivity can potentially be improved whilst their density is reduced. Although casting has many advantages in the fabrication of large, complex components, this process cannot be easily employed when manufacturing CNTs-Al composites. In order to produce CNTs-Al matrix composites by casting a CNTs-Al powder precursor was manufactured using mechanical milling and electroless plating processes.
