Crystalized hydrogen
WebApr 1, 2024 · Graphitic carbon nitride (g-C 3 N 4) has emerged as a remarkably promising photocatalyst for addressing environmental and energy issues; however, it exhibits only moderate photocatalytic activity because of its low specific surface area and high recombination of carriers.Preparation of crystalline g-C 3 N 4 by the molten salt method … In March 1996, a group of scientists at Lawrence Livermore National Laboratory reported that they had serendipitously produced the first identifiably metallic hydrogen for about a microsecond at temperatures of thousands of kelvins, pressures of over 100 GPa (1,000,000 atm; 15,000,000 psi), and densities of approximately 0.6 g/cm . The team did not expect to produce metallic hydrogen, as it was not using solid hydrogen, thought to be necessary, and was working at temperatures a…
