The dry particles are tested for BET surface area and that value is correlated back to an average particle size based on historical data and known relationships between these parameters. The particle size is not tested directly.

As with all types of fuel cells, a Solid Oxide Fuel Cell (SOFC) is capable of efficiently transforming chemical energy into electrical energy.
Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

通常cerium oxide nanoparticlesの水分散液は透明な黄緑色ですが、御社の製品であるcerium (IV) oxide, dispersion (643009)は不透明な白濁液です。可視光を遮断する為に白濁させている様ですが、何か保護剤は添加されておりますでしょうか？
1 answer-
No protective agents are added to block visible light. The off-white appearance is simply due to the dispersion of the Cerium(IV) Oxide nanopowder in the water.
