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 in 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 provides several key advantages to the public and the fields of medicine by allowing for basic needs to be met and allowing for the production of medicines. Chemistry, indirectly and directly, provides benefits for people around the world on a daily basis. It helps meet basic needs such as clothing, energy and shelter, and contributes to the improvement of air, water and soil quality.Full Answer >
In chemistry, the constant R stands for the universal gas constant. R is equal to 8.31 joules per mole-Kelvin or 0.08 liter-atmospheres per mole-Kelvin. It is the expression of the Boltzmann constant, k, in units of energy.Full Answer >
