full_context: Document 1: Charles J.

He shared the Nobel Prize in Chemistry in 1987 with Donald J. Cram and Jean-Marie Lehn. His Japanese first name was Yoshio (良男 ) . He is the only Nobel Prize laureate born in Korea other than Peace Prize laureate Kim Dae-jung.

Document 3: Peter Debye: Peter Joseph William Debye {'1': ", '2': ", '3': 'ForMemRS', '4': "} ( ; ] ; March 24, 1884 – November 2, 1966) was a Dutch-American physicist and physical chemist, and Nobel laureate in Chemistry.
Document 4: Yasar Onel: Yasar Onel is a Turkish-born physicist who holds Swiss and American citizenship. He received his Ph.D. in Physics from London University in 1975. He worked at the Queen Mary University of London in the United Kingdom, and Neuchatel and Geneva Universities in Switzerland before joining the University of Texas at Austin in 1986. Then, he moved to the University of Iowa in 1988. He is a tenured faculty professor. of Physics at the University of Iowa in Iowa City, IA, USA.
Document 5: Common ion effect: The common ion effect is responsible for the reduction in the solubility of an ionic precipitate when a soluble compound containing one of the ions of the precipitate is added to the solution in equilibrium with the precipitate. It states that if the concentration of any one of the ions is increased, then, according to Le Chatelier's principle, some of the ions in excess should be removed from solution, by combining with the oppositely charged ions. Some of the salt will be precipitated until the ion product is equal to the solubility product. In short, the common ion effect is the suppression of the degree of dissociation of a weak electrolyte containing a common ion.
Document 6: Debye–Hückel equation: The chemists Peter Debye and Erich Hückel noticed that solutions that contain ionic solutes do not behave ideally even at very low concentrations. So, while the concentration of the solutes is fundamental to the calculation of the dynamics of a solution, they theorized that an extra factor that they termed gamma is necessary to the calculation of the activity coefficients of the solution. Hence they developed the Debye–Hückel equation and Debye–Hückel limiting law. The activity is only proportional to the concentration and is altered by a factor known as the activity coefficient formula_1. This factor takes into account the interaction energy of ions in the solution.
Document 7: Paul D. Boyer: Paul Delos Boyer (born July 31, 1918) is an American biochemist, analytical chemist, and a professor of chemistry at University of California Los Angeles (UCLA) . He shared the 1997 Nobel Prize in Chemistry for research on the "enzymatic mechanism underlying the biosynthesis of adenosine triphosphate (ATP)" (ATP synthase) with John E. Walker, making Boyer the only Utah-born Nobel laureate; the remainder of the Prize in that year was awarded to Danish chemist Jens Christian Skou for his discovery of the Na+/K+-ATPase. He is the oldest living Nobel laureate at age 99 .
Document 8: Induced-charge electrokinetics: Induced-charge electrokinetics in physics is the electrically driven fluid flow and particle motion in a liquid electrolyte. Consider a metal particle (which is neutrally charged but electrically conducting) in contact with an aqueous solution in a chamber/channel. If different voltages apply to the end of this chamber/channel, electric field will generate in this chamber/channel. This applied electric field passes through this metal particle and causes the free charges inside the particle migrate under the skin of particle. As a result of this migration, the negative charges moves to the side which is close to the positive (or higher) voltage while the positive charges moves to the opposite side of the particle. These charges under the skin of conducting particle attract the counter-ions of the aqueous solution; thus, the electric double layer (EDL) forms around the particle. The EDL sing on the surface of the conducting particle changes from positive to negative and the distribution of the charges varies along the particle geometry. Due to these variations, the EDL is non-uniform and has different sings. Thus, the induced zeta potential around the particle, and consequently slip velocity on the surface of the particle, vary as a function of local electric field. Differences in magnitude and direction of slip velocity on the surface of the conducting particle effects the flow pattern around this particle and causes micro vortices. Yasaman Daghighi and Dongqing Li, for the first time, experimentally illustrated these induced vortices around a 1.2mm diameter carbon-steel sphere under the 40V/cm Direct Current (DC) external electric filed.
Document 9: Debye–Hückel theory: The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. It is a linearized Poisson–Boltzmann model, which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean activity coefficients for ions in dilute solution. The Debye–Hückel equation provides a starting point for modern treatments of non-ideality of electrolyte solutions.
Document 10: Murray Gell-Mann: Murray Gell-Mann ( ; born September 15, 1929) is an American physicist who received the 1969 Nobel Prize in physics for his work on the theory of elementary particles. He is the Robert Andrews Millikan Professor of Theoretical Physics Emeritus at the California Institute of Technology, a Distinguished Fellow and co-founder of the Santa Fe Institute, Professor in the Physics and Astronomy Department of the University of New Mexico, and the Presidential Professor of Physics and Medicine at the University of Southern California.
