Latest Patents

Helferich's latest patents include advancements in cement compositions and methods for preparing them. One of his notable inventions involves cement compositions that incorporate at least one oxide with a particle size of less than about 600 nm. The methods for making this cement involve a mixture of compounds containing essential elements such as calcium, silicon, aluminum, and iron. This mixture is then combined with a fuel source and an oxidizer, which ignites to form various calcium silicates and aluminates. Another significant patent addresses the production of iron/surfactant-modified zeolite pellets designed to retain and destroy water pollutants. This method involves mixing an adsorbent with a pollutant-transforming agent, compacting the mixture to form a highly permeable article, and potentially modifying it with surfactants.
