TL;DR: Overall, it is shown that defects can be engineered to lower the phase transformation onset pressure by ~50% in the ordered pyrochlore Dy2Ti2O7, and lower thephase transformation completion pressure by~20% inThe disordered pyroChlore Dy 2Zr2O 7 without significantly sacrificing mechanical integrity, as characterized by bulk modulus.

TL;DR: This work brings the compression-induced conductivity of Cu-halide perovskites to more technologically accessible pressures and notable enhancement of the Br perovkite's electronic response to pressure may be attributed to more diffuse Br valence orbitals relative to Cl orbitals.

TL;DR: In this paper, the authors used pump-probe spectroscopy to study the phonon response of mixed-valence perovskite Cs${}{2}$Au${}_{2+}$I${}$6}$ using high pressure in a diamond-anvil cell.

TL;DR: In this article, a review focusing on the perspective of high-pressure chemical hydrogen storage related to NH3BH3-based materials is presented, where four main aspects are discussed: the structures and bonding of NH3bH3 over a wide pressure-temperature space, thermolysis of NHbH 3 at high pressure, the formation of a novel high pressure H-rich compound as a result of storage of additional molecular H2 in NH3 borane, and the potential rehydrogenation of the thermally decomposed NH3h3 under the

TL;DR: In this article, the authors used high pressure Raman spectroscopy to study the evolution of vibrational frequencies of the phase change materials (PCMs) Ge2Sb2Te5, GeSb 2Te4, and SnSb 1Te4 and found that the critical pressure for triggering amorphization decreases with increasing vacancy concentration.
