Here is a question about this article: 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 is the answer to this question: How is hydrogen used in oxide materials?
****
So... a potential electron donor

Here is a question about this article: Eisenhower returned to the U.S. in December 1939 and was assigned as a battalion commander and regimental executive officer of the 15th Infantry at Fort Lewis, Washington. In March 1941 he was promoted to colonel and assigned as chief of staff of the newly activated IX Corps under Major General Kenyon Joyce. In June 1941, he was appointed Chief of Staff to General Walter Krueger, Commander of the 3rd Army, at Fort Sam Houston in San Antonio, Texas. After successfully participating in the Louisiana Maneuvers, he was promoted to brigadier general on October 3, 1941. Although his administrative abilities had been noticed, on the eve of the U.S. entry into World War II he had never held an active command above a battalion and was far from being considered by many as a potential commander of major operations.
What is the answer to this question: In the spring of 1941, who commanded IX Corps?
****
So... Kenyon Joyce

Here is a question about this article: The first indigenous group encountered by Columbus were the 250,000 Tainos of Hispaniola who represented the dominant culture in the Greater Antilles and the Bahamas. Within thirty years about 70% of the Tainos had died. They had no immunity to European diseases, so outbreaks of measles and smallpox ravaged their population. Increasing punishment of the Tainos for revolting against forced labour, despite measures put in place by the encomienda, which included religious education and protection from warring tribes, eventually led to the last great Taino rebellion.
What is the answer to this question: What led to the last great Tainos rebellion?
****
So...
Increasing punishment
