Andrew Benson
Andrew Alm Benson (September 24, 1917 – January 16, 2015) was an American biologist and a professor of biology at the University of California, San Diego, until his retirement in 1989. He is known for his work in understanding the carbon cycle in plants. Early life and education Benson was born on September 24, 1917, in Modesto, California, the son of a rural physician of Swedish immigrant stock.. He studied as an undergraduate and masters student at the University of California, Berkeley, where he learned optics from Luis Alvarez and worked in the chemistry lab of Glenn T. Seaborg. In 1942, he received his Ph.D. from the California Institute of Technology;. at Caltech, he worked under the supervision of Carl Niemann, conducting experiments on the fluorination of thyroxine; his later thesis work concerned "periodate and lead tetraacetate degradation of its vicinal amino glycol". At that time he also became a conscientious objector to the war in Europe, a political positi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modesto, California
Modesto () is the county seat and largest city of Stanislaus County, California, United States. With a population of 218,464 at the 2020 census, it is the 19th largest city in the state of California and forms part of the Sacramento-Stockton-Modesto Combined Statistical Area.

Vicinal (chemistry)
In chemistry the descriptor vicinal (from Latin ''vicinus'' = neighbor), abbreviated ''vic'', describes any two functional groups bonded to two adjacent carbon atoms (i.e., in a 1,2-relationship). Relation of atoms in a molecule For example, the molecule 2,3-dibromobutane carries two vicinal bromine atoms and 1,3-dibromobutane does not. Mostly, the use of the term vicinal is restricted to two ''identical'' functional groups. Likewise in a ''gem-''dibromide the prefix ''gem'', an abbreviation of geminal, signals that both bromine atoms are bonded to the ''same'' atom (i.e., in a 1,1-relationship). For example, 1,1-dibromobutane is geminal. While comparatively less common, the term hominal has been suggested as a descriptor for groups in a 1,3-relationship. Like other such descriptors as syn, anti, exo or endo, the description ''vicinal'' helps explain how different parts of a molecule are related to each other either structurally or spatially. The vicinal adjective is sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Bassham
James Alan Bassham (November 26, 1922 – November 19, 2012) was an American scientist known for his work on photosynthesis. He received a B.S. degree in chemistry in 1945 from the University of California, Berkeley, earning his Ph.D. degree from Berkeley in 1949. His graduate studies were on the subject of carbon reduction during photosynthesis, working with Melvin Calvin in the Bio-Organic Chemistry Group of the Lawrence Radiation Laboratory at the University of California. He discovered, with Melvin Calvin and Andrew Benson, the Calvin-Benson-Bassham cycle. He continued his work as Associate Director of this group. Besides his work on the basic carbon reduction cycle of photosynthesis, Bassham conducted research on the biosynthetic paths leading from the cycle to the thermodynamics and kinetics of the carbon paths and the factors that control the flow of material and energy in this metabolic network. He is coauthor (with Melvin Calvin Melvin Ellis Calvin (April 8, 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fulbright Program
The Fulbright Program, including the Fulbright–Hays Program, is one of several United States Cultural Exchange Programs with the goal of improving intercultural relations, cultural diplomacy, and intercultural competence between the people of the United States and other countries, through the exchange of persons, knowledge, and skills. Via the program, competitively-selected American citizens including students, scholars, teachers, professionals, scientists, and artists may receive scholarships or grants to study, conduct research, teach, or exercise their talents abroad; and citizens of other countries may qualify to do the same in the United States. The program was founded by United States Senator J. William Fulbright in 1946 and is considered to be one of the most widely recognized and prestigious scholarships in the world. The program provides approximately 8,000 grants annually – roughly 1,600 to U.S. students, 1,200 to U.S. scholars, 4,000 to foreign students, 900 to f ...

Ernest Lawrence
Ernest Orlando Lawrence (August 8, 1901 – August 27, 1958) was an American nuclear physicist and winner of the Nobel Prize in Physics in 1939 for his invention of the cyclotron. He is known for his work on uranium-isotope separation for the Manhattan Project, as well as for founding the Lawrence Berkeley National Laboratory and the Lawrence Livermore National Laboratory. A graduate of the University of South Dakota and University of Minnesota, Lawrence obtained a PhD in physics at Yale in 1925. In 1928, he was hired as an associate professor of physics at the University of California, Berkeley, becoming the youngest full professor there two years later. In its library one evening, Lawrence was intrigued by a diagram of an accelerator that produced high-energy particles. He contemplated how it could be made compact, and came up with an idea for a circular accelerating chamber between the poles of an electromagnet. The result was the first cyclotron. Lawrence went o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclotron
A cyclotron is a type of particle accelerator invented by Ernest O. Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. Lawrence, Ernest O. ''Method and apparatus for the acceleration of ions'', filed: January 26, 1932, granted: February 20, 1934 A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention. The cyclotron was the first "cyclical" accelerator. The primary accelerators before the development of the cyclotron were electrostatic accelerators, such as the Cockcroft–Walton accelerator and Van de Graaff generator. In these accelerators, particles would cross an accelerating electric field only once. Thus, the energy gained by the particles was limited by the maximum elec ...

Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...
