Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

The dispersion properties of boron carbide (B4C) microparticles in aqueous media were investigated by measuring the particle size distribution, the dispersibility, and the zeta potential as these properties relate to their application as neutron absorbers in fuel-storage pool water. The B4C powder is composed of particles with a narrow size distribution, with a d50 (mean diameter) of 0.65 m. The amount of B4C particles dispersed decreased exponentially with increasing dispersion time. The dispersibility of B4C particles increased with an increase in the loading of B4C particles and reached a maximum value at 12.91 wt%. The zeta potential of the B4C suspension was measured as a function of pH and temperature. The B4C suspension has a negative zeta potential value in the pH range between 2 and 12. The dispersion of B4C particles was not greatly influenced by the addition of boric acid (H3BO3). The absolute value of the zeta potential decreased with increasing temperature.
