Web8 de fev. de 2024 · A significant increase in the stability of the catalyst composition comprising ZrO 2 can be achieved with more than a 100-fold increase in the catalyst's half-life. Without being bound by any particular theory, this increase in stability may be attributable to two factors: 1) the continuous regeneration of Zr active sites; and 2) the … Web9 de ago. de 2024 · New research initiative turns laser focus on high-energy-density physics. Atoms behave much differently when squeezed to pressures more than a million—or even a billion—times the atmospheric pressure on Earth. Understanding how atoms react under such high-pressure conditions can lead to the creation of new materials and give …
