Nevertheless, in Brazil, for more than 40 years there has been the discontinuation of research for a thorium-fueled reactor, and so far there has been no prospect of future projects. The AHWR is an important example as an alternative way of producing energy in Brazil, as the country has the second largest reserve of thorium on the planet.

Both materials present a highly negative zeta potential in deionized water, −41.33 ± 0.5 mV and −40.34 ± 0.76 mV for GO and MoS 2 respectively. However, the contact angle measurements of GO and MoS 2 were 25 ± 5.4 and 42 ± 4.6, respectively, suggesting that GO was slightly more hydrophilic than MoS 2.
