Famous Filipino scientists include Dr. Alfredo Santos, Anacleto Del Rosario, Amando Kapauan, Dr. Jose O. Juliano and Julian A. Banzon. Their contributions to chemistry ranged from nuclear physics research to the production of alternative fuels from sugarcane and coconut.Know More
Dr. Alfredo Santos conducted extensive research in the chemistry of natural harvest. His works include the segregation and elucidation of alkaloids from medicinal plants found in the Philippines. He received an award as an Outstanding Pharmacist Researcher of the Philippine Pharmaceutical Association in 1953 and the PhilAAS Outstanding Scientist Award in 1973.
Anacleto Del Rosario created a formula for producing pure alcohol from the tuba of a nipa palm. He won first prize at the World Fair in 1881. He also formulated how to extract castor oil from a Filipino plant called Palma Christi.
Amando Kapauan specialized in environmental chemistry. He conducted research into the effects of heavy metals in the environment, focusing on the mercury found in water, fish and the Filipino soil. He also helped develop chemical instrumentation that worked with computers.
Dr. Jose O. Juliano researched nuclear chemistry and physics. His particular contributions relate to his published work, especially "Rapid and Non-destructive Analysis of Sulfur and Calcium by Radioactivation and Photoneutron Counting" and "Disintegration of Iron-52 and Iron-53," which increase understanding of nuclear science.
Julian A. Banzon researched renewable sources of chemicals and fuels. He particularly focused on the production of ethyl esters from coconut and sugarcane.Learn more about Chemistry
In chemistry, pK is the logarithmic value of the dissociation constant, Ka, of a hydrogen atom present on a molecule. A molecule has a distinct pK for each hydrogen atom that can be deprotonated. The acidity of a specific hydrogen atom in a molecule is represented by the pK value.Full Answer >
Chromatography is used by scientists to separate, analyze and identify the individual parts of a mixture. For example, chromatography was used to create synthetic insulin and to understand how the sun's energy is used by plants to make food.Full Answer >
Chemistry is basic to essentially every field of science. A working knowledge of chemistry informs medicine, energy production and the vast majority of industrial processes. A comprehensive theory of chemistry allows predictions to be made about how any substance in the universe will behave in the presence of any other substance.Full Answer >
In a molecular formula, a subscript is written immediately after the letter denoting an element and refers to the amount of atoms that element has. A molecular formula, or empirical formula, is noted as a series of letters and numbers that represent a compound, or a molecule. Each letter in a formula symbolizes one element from the periodic table of elements.Full Answer >
