Latest Patents

Among Nakagawa's latest inventions is a patent entitled "Process for producing micro-beads and product containing the same." This innovation describes a method for creating micro-beads characterized by a carbonaceous structure. The process involves heating pitch within a temperature range of approximately 350 to 500 degrees Celsius to form optically anisotropic spherules. These spherules are then extracted using an organic solvent to eliminate any residual pitch and subsequently carbonized in a non-oxidizing atmosphere. When carbonized at temperatures exceeding 1500 degrees Celsius, these micro-beads yield a graphite crystalline structure, showcasing their considerable versatility in application.

His second notable patent relates to "Thiohumic acid, a process for preparing same, and its use for absorbing." This invention introduces thiohumic acid, a compound derived from the modification of humic acid through the replacement of carboxyl groups with thiocarboxyl groups. The method involves treating humic acid with a halogenating agent to produce a humic acid halide, which is subsequently processed with a thiolating agent. This innovative compound serves as a heavy metal adsorbent, demonstrating its potential usefulness in environmental remediation.
