Problem: The Spanish ship San Pedro and two other vessels in an expedition commanded by Miguel López de Legazpi discovered an island on January 9, 1530, possibly Mejit, at 10°N, which they named "Los Barbudos". The Spaniards went ashore and traded with the local inhabitants. On January 10, the Spaniards sighted another island that they named "Placeres", perhaps Ailuk; ten leagues away, they sighted another island that they called "Pajares" (perhaps Jemo). On January 12, they sighted another island at 10°N that they called "Corrales" (possibly Wotho). On January 15, the Spaniards sighted another low island, perhaps Ujelang, at 10°N, where they described the people on "Barbudos". After that, ships including the San Jeronimo, Los Reyes and Todos los Santos also visited the islands in different years.
What is thought to be the modern name of the island Legazpi called Los Barbudos?

Problem: Hydrogen is employed to saturate broken ("dangling") bonds of amorphous silicon and amorphous carbon that helps stabilizing material properties. It is also a potential electron donor in various oxide materials, including ZnO, SnO2, CdO, MgO, ZrO2, HfO2, La2O3, Y2O3, TiO2, SrTiO3, LaAlO3, SiO2, Al2O3, ZrSiO4, HfSiO4, and SrZrO3.
What oxide materials use hydrogen as an electron donor?

Answer:
ZnO, SnO2, CdO, MgO, ZrO2, HfO2, La2O3, Y2O3, TiO2, SrTiO3, LaAlO3, SiO2, Al2O3, ZrSiO4, HfSiO4, and SrZrO3
