Actinium (III) oxide is a chemical compound containing the rare radioactive element actinium. It has the formula Ac 2 O 3. It is similar to its corresponding lanthanum compound, lanthanum (III) oxide, and contains actinium in the oxidation state +3. [2][3] Actinium oxide is not to be confused with Ac 2 O (acetic anhydride), where Ac is an ...
Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. [1] Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication ...
Actinium is a chemical element; it has symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name emanium; the element got its name by being wrongly identified with a substance André-Louis Debierne found in 1899 and called actinium. The actinide series, a set of 15 elements between actinium ...
Actinium(III) oxide is the only oxide that actinium can form, with the chemical formula Ac 2 O 3. In this compound, actinium is in the oxidation state +3. [1] [10] It is similar to the corresponding lanthanum compound, lanthanum(III) oxide. It can be obtained by heating the hydroxide at 500 °C or the oxalate at 1100 °C, in vacuum.
A reversible solid oxide cell (rSOC) is a solid-state electrochemical device that is operated alternatively as a solid oxide fuel cell (SOFC) and a solid oxide electrolysis cell (SOEC). Similarly to SOFCs, rSOCs are made of a dense electrolyte sandwiched between two porous electrodes. Their operating temperature ranges from 600°C to 900°C ...
One type of fibre optic temperature probe consists of a gallium arsenide (GaAs) semiconductor crystal that is mounted on the end of an optical fibre. The probe is completely non-metallic. The fibre optical sensor is completely non-conductive and offers complete immunity to RFI, EMI, NMR and microwave radiation with high temperature operating ...
