Composite material aluminum boron is characterized by a combination of high strength

What is Aluminum Boride?Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride will be transformed into a superconductor at an absolute temperature of slightly 40K (equivalent to -233 ℃). And its actual operating temperature is 20 ~ 30K. We can use liquid neon, liquid hydrogen, or a closed-cycle refrigerator to finish cooling to reach this temperature. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler

βFe2O3 was found to transform into a completely new crystal structure

Surprisingly, β-Fe2O3 was found to transform into a completely new crystal structure following the Rietveld refinement of the synchrotron radiation XRD patterns recorded at pressures above 30 GPa. The analyses were carried out adopting the following scenario. At high pressures (42.9–64.4 GPa), α-Fe2O3 transforms into RO-Fe2O3 and PPV-Fe2O3 with consistent transition pressures compared with the previous reports. On the other hand, β-Fe2O3 transits to a different new phase. By indexing these new p

Zeta Fe2O3 A new stable polymorph in iron III oxide family

Iron(III) oxide shows a polymorphism, characteristic of the existence of phases with the same chemical composition but distinct crystal structures and, hence, physical properties. Four crystalline phases of iron(III) oxide have previously been identified: α-Fe2O3 (hematite), β-Fe2O3, γ-Fe2O3 (maghemite), and ε-Fe2O3. All four iron(III) oxide phases easily undergo various phase transformations in response to heating or pressure treatment, usually forming hexagonal α-Fe2O3, the most thermodynamica

What is ATO renewal

"ATOs are traditionally issued for three years and renewed every three years based on an updated security authorization package, including a new security assessment report and updated system security plan and plan of action and milestones," Berlas adds. If you're lodging your tax return, you need to lodge it by Oct 31 each year. If Oct 31 falls on a weekend, the due date to lodge your tax return is the next day after Oct 31. The ATO is the authority to operate decision that culminates from the s

Quartz in Glass

What is Quartz?Quartz, the most common of all minerals, is composed of silicon dioxide, or silica, SiO2. It is an essential component of igneous and metamorphic rocks. The size varies from specimens weighing a metric ton to minute particles that sparkle on rock surfaces. The luster in some specimens is vitreous; in others, it is greasy or glossy. Some specimens are transparent; others are translucent. In pure form, Quartz is colorless, but impurities commonly color it. Rock crystal is a colorles

Improved Ductility of Boron Carbide by Microalloying with Boron Suboxide

What is Boron carbide?Boron carbide (B4C) is the third hardest material in nature, but applications are hindered by its brittle failure under impact. We found that this brittle failure of B4C arises from amorphous shear band formation due to the deconstruction of icosahedral clusters, and based on this model, we suggest and validate with quantum mechanics (QM, PBE flavor of density functional theory) that a laminated B4C–B6O composite structure will eliminate this brittle failure. Using QM to ap
