George Crabtree
George William Crabtree (November 28, 1944 – January 23, 2023) was an American physicist known for his highly cited research on superconducting materials and, since 2012, for his directorship of thJoint Center for Energy Storage Research(JCESR) at Argonne National Laboratory. Early life and education George Crabtree was born on November 28, 1944, in Little Rock, Arkansas, and moved with his family to Hillside, Illinois, at age 2. His father was a mechanical engineer for International Harvester, and his mother was a homemaker and community service volunteer. Crabtree attended Proviso West High School in Hillside, Illinois, followed by Northwestern University, where he received a B.S. in science engineering in 1967. For graduate school, he first attended the University of Washington in Seattle, where he received an M.S. in physics in 1968, then the University of Illinois at Chicago, where he attained his Ph.D. in condensed matter physics in 1974.

Multivalent
In chemistry, polyvalency (or polyvalence, multivalency) is the property of chemical species (generally atoms or molecules) that exhibit more than one valence by forming multiple chemical bonds (Fig. 1). A bivalent species can form two bonds; a trivalent species can form three bonds; and so on. The principle of polyvalency also applies to larger species, such as antibodies, medical drugs, and even nanoparticles surface-functionalized with ligands, like spherical nucleic acids, which can show enhanced or cooperative binding compared to their monovalent counterparts. Nanoparticles with multiple nucleic acid Nucleic acids are biopolymers, macromolecules, essential to all known forms of life. They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base. The two main cl ... strands on their surfaces (e.g., DNA) can form multiple bonds with one another by DNA hybridization to form hierarchical asse ...

People From Little Rock, Arkansas
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

University Of Illinois Chicago Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Kamerlingh Onnes Prize
The Heike Kamerlingh Onnes Prize was established in 2000, under the sponsorship of Elsevier, by the organizers of the International Conference on the Materials and Mechanisms of Superconductivity (M2S). The prize is named in honor of Heike Kamerlingh Onnes, who discovered superconductivity in 1911. At each conference, the prize, which consists of 7500 € and a certificate, is presented to one or more physicists. If there are two or more recipients they share the money. The prize "recognizes outstanding experiments which illuminate the nature of superconductivity other than materials". The winners are selected by the members of the Kamerlingh Onnes Prize Committee, appointed by the conference organizers. The prize was first awarded in 2000 at the 6th International Conference on Materials and Mechanisms of Superconductivity and High Temperature Superconductors: The prize is "one of the leading awards for experimental research in superconductivity."

Fellow Of The American Academy Of Arts And Sciences
The American Academy of Arts and Sciences (abbreviation: AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a thorough petition, review, and election process. The academy's quarterly journal, ''Dædalus'', is published by MIT Press on behalf of the academy. The academy also conducts multidisciplinary public policy research. History The Academy was established by the Massachusetts legislature on May 4, 1780, charted in order "to cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people." The sixty-two incorporating fellows represented varying interests and high standing in the political, professional, and commercial secto ...
