Which of the following seed is Do used in production of engineered diamonds?
Detailed Explanation:
Graphite serves as the carbon seed material in engineered diamond production using HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition) methods.
Under extreme conditions, carbon atoms in graphite rearrange into the diamond crystal lattice structure, while Moissanite, White Sapphire, and Cubic Zirconia are merely diamond simulants, not production seeds.
Which of the following laboratories claimed a historic nuclear fusion breakthrough in December 2022?
Detailed Explanation:
Lawrence Livermore National Laboratory (LLNL) in California achieved a historic nuclear fusion breakthrough in December 2022.
The National Ignition Facility (NIF) at LLNL successfully demonstrated net energy gain from fusion for the first time, where energy output exceeded energy input in a controlled fusion reaction.
Los Alamos and Oak Ridge National Laboratories are prominent U.S. research facilities but were not involved in this specific fusion milestone.
