English: Republic Act No. 10931 (Universal Access to Quality Tertiary Education Act) PDF file on the Official Gazette of the Republic of the Philippines website, signed by President Rodrigo Duterte on August 3, 2017
The Universal Access to Quality Tertiary Education Act, officially designated as Republic Act 10931, is a Philippine law that institutionalizes free tuition and exemption from other fees in state universities and colleges (SUCs), and local universities and colleges (LUCs) in the Philippines. The law also foresees subsidies for private higher ...

Oxygen evolution is the chemical process of generating elemental diatomic oxygen (O 2) by a chemical reaction, usually from water, the most abundant oxide compound in the universe. Oxygen evolution on Earth is effected by biotic oxygenic photosynthesis , photodissociation , hydroelectrolysis , and thermal decomposition of various oxides and ...
However, there are known materials that can mediate the reduction step efficiently therefore much of the current research is aimed at the oxidation half reaction also known as the Oxygen Evolution Reaction (OER). Current research focuses on understanding the mechanism of OER and development of new materials that catalyze the process. [3]
Thus, the volumes of hydrogen and oxygen which combine (i.e., 100mL and 50mL) bear a simple ratio of 2:1, as also is the case for the ratio of product water vapor to reactant oxygen. Based on Gay-Lussac's results, Amedeo Avogadro hypothesized in 1811 that, at the same temperature and pressure, equal volumes of gases (of whatever kind) contain ...
Oxygen gas can also be produced through electrolysis of water into molecular oxygen and hydrogen. DC electricity must be used: if AC is used, the gases in each limb consist of hydrogen and oxygen in the explosive ratio 2:1. A similar method is the electrocatalytic O 2 evolution from oxides and oxoacids.
A special type of wet oxidation process was the so-called "VerTech process" system. A system of this type operated in Apeldoorn, Netherlands between 1994 and 2004. The system was installed in a below-ground pressure vessel (also called a gravity pressure vessel or GPV). The pressure was supplied by feeding the material to a reactor with a depth ...
