Patent • #US9514864B2. A flexible solid-state resistor comprises a string of ceramic resistors that can be used to charge the capacitors of a linear transformer driver (LTD) used in a pulsed power machine. The solid-state resistor is able to absorb the energy of a switch prefire, thereby limiting LTD cavity damage, yet...

Patent • #US12500415B1. A high altitude electromagnetic pulse (HEMP) or other similar geomagnetic disturbance (GMD) has the potential to severely impact the operation of large-scale electric power grids by introducing low-frequency common-mode (CM) currents which deteriorate the performance of key grid components, such as large power transformers. A solid-state transformer (SST) can...

A Ge(II) precursor is dissolved in a ligand heated to a temperature, generally between approximately 100° C. and 400° C., sufficient to thermally reduce the Ge(II) to Ge(0), where the ligand is a compound...

Patent • #US11600856B2. A sodium-ion conducting NaSICON ceramic can be densified via the addition of a solvent to a NaSICON powder and subsequent pressing under high pressure and mild heat. Densification to ˜90% relative density can be achieved, providing a path toward low-temperature fabrication of Na-ion conductors.

Patent • #US11718536B2. Lanthanide oxides and mixed lanthanide oxides can be produced using furnace or microwave assisted solid-state synthesis. The use of Ln-tri(methylsilyl)amide-based precursors yields spherical nanoparticles. The formation of spherical shaped nanoparticles is likely due to the preferential single-step decomposition of the Ln-TMS as well as the low activation energy to...

Patent • #US11773046B2. A facile solvothermal method can be used to synthesize metal alkanoate nanoparticles using a metal nitrate precursor, alcohol/water, and alkanoic acid. The method can produce lanthanide (e.g., La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, or Yb) and transition metal (e.g., Ag, Co, Cu, or...
