John P. Ferraris
John P. Ferraris (April 1947 – May 2025) was an American chemist and professor at the University of Texas at Dallas. He was known for his pioneering work in the field of organic electronics, particularly the discovery that a charge-transfer complex between tetrathiafulvalene (TTF) and tetracyanoquinodimethane (TCNQ) exhibits high electrical conductivity.Ferraris, J. P.; Cowan, D. O.; Walatka, V.; Perlstein, J. H. (1973). "Electron transfer in a new highly conducting donor-acceptor complex". ''Journal of the American Chemical Society''. 95 (3): 948–949. doi: 0.1021/ja00784a066https://doi.org/10.1021/ja00784a066). This finding helped establish the foundation for the development of conducting polymers and organic electronic materials. Early life and education Ferraris earned his B.A. in chemistry from Saint Michael's College in Vermont in 1969. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tetrathiafulvalene
Tetrathiafulvalene (TTF) is an organosulfur compound with the formula . It is the parent of many tetrathiafulvenes. Studies on these heterocyclic compound contributed to the development of molecular electronics, although no practical applications of TTF emerged. TTF is related to the hydrocarbon fulvalene () by replacement of four CH groups with sulfur atoms. Over 10,000 scientific publications discuss TTF and its derivatives. Preparation The high level of interest in TTFs spawned many syntheses of TTF and its analogues. Most preparations entail the coupling of cyclic building blocks such as 1,3-dithiole-2-thion or the related 1,3-dithiole-2-ones. For TTF itself, the synthesis begins with the cyclic trithiocarbonate ( 1,3-dithiole-2-thione), which is ''S''-methylated and then reduced to give (1,3-dithiole-2-yl methyl thioether), which is treated as follows: Protonolysis of a thioether: : Followed by deprotonation of the dithiolium cation with triethylamine: : Redox prop ...

Tetracyanoquinodimethane
Tetracyanoquinodimethane (TCNQ) is an organic compound with the chemical formula . It is an orange crystalline solid. This cyanocarbon, a relative of para-quinone, is an electron acceptor that is used to prepare charge transfer salts, which are of interest in molecular electronics. Preparation and structure TCNQ is prepared by the condensation of 1,4-cyclohexanedione with malononitrile, followed by dehydrogenation of the resulting diene with bromine: : : The molecule is planar, with D2h symmetry. Reactions Like tetracyanoethylene (TCNE), TCNQ is easily reduced to give a blue-coloured radical anion. The reduction potential is about −0.3 V relative to the ferrocene/ ferrocenium couple. This property is exploited in the development of charge-transfer salts. TCNQ also forms complexes with electron-rich metal complexes. Charge transfer salts TCNQ achieved great attention because it forms charge-transfer salts with high electrical conductivity. These discoveries were inf ...

Conducting Polymers
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that Electrical conductance, conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The main advantage of conductive polymers is that they are easy to process, mainly by Dispersion (chemistry), dispersion. Conductive polymers are generally not thermoplastics, ''i.e.'', they are not thermoformable. But, like insulating polymers, they are organic materials. They can offer high electrical conductivity but do not show similar mechanical properties to other commercially available polymers. The electrical properties can be fine-tuned using the methods of organic synthesis and by advanced dispersion techniques. History Polyaniline was first described in the mid-19th century by Henry Letheby, who investigated the electrochemical and chemical oxidation products of aniline in acidic media. He noted that the reduced form was colourless but the oxidized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saint Michael's College
Saint Michael's College (St. Mikes) is a private Catholic college in Colchester, Vermont, United States. Founded in 1904 by the Society of Saint Edmund, it grants Bachelor of Arts and Bachelor of Science degrees in more than 40 majors to about 1,200 undergraduate students. Housing availability is guaranteed for all four years, and 92% of students live on campus. History In 1889, priests from the Society of Saint Edmund fled to the United States after widespread anti-clericalism swept France. In 1904, they opened Saint Michael's Institute with an initial investment of $5,000. Thirty-four students aged 10 to 22 enrolled, with a tuition and board fee of $105. Slowly, the school discontinued its high school program. Gradually, the school transitioned from an academy to a traditional residential college. In 1939, graduate programs were offered for the first time. Saint Michael's Playhouse was opened in 1947, bringing professional summer theater to Vermont, and giving students t ...

Johns Hopkins University
The Johns Hopkins University (often abbreviated as Johns Hopkins, Hopkins, or JHU) is a private university, private research university in Baltimore, Maryland, United States. Founded in 1876 based on the European research institution model, Johns Hopkins is considered to be the first research university in the U.S. The university was named for its first benefactor, the American entrepreneur and Quakers, Quaker philanthropist Johns Hopkins. Hopkins's $7 million bequest (equivalent to $ in ) to establish the university was the largest Philanthropy, philanthropic gift in U.S. history up to that time. Daniel Coit Gilman, who was inaugurated as :Presidents of Johns Hopkins University, Johns Hopkins's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research.

NanoTech Institute
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter. This definition of nanotechnology includes all types of research and technologies that deal with these special properties. It is common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to research and applications whose common trait is scale. An earlier understanding of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabricating macroscale products, now referred to as molecular nanotechnology. Nanotechnology defined by scale includes fields of science such as surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, engineering, microfabrication, and molecular engineering. The associated rese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint Michael's College Alumni
In Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but a selected few are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. In many Protestant denominations, and following from Pauline usage, ''saint'' refers broadly to any holy Christian, without special recognition or selection. While the English word ''saint'' (deriving from the Latin ) originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special ...
