North Dakota State University - DateApril 6, 2021Glass and its uses predate recorded history. The production of synthetic glass, however, is thought to date to no earlier than 3000 BCE…
Presenter
North Dakota State University - DateApril 15, 2021The most commonly applied approach to the generation of low bandgap (_Eg_ < 1.5 eV) and reduced bandgap (_Eg _= 1.5-2.0 eV) conjugated polymers is via the utilization of a donor-acceptor (D-A) framework…

- DateAugust 23, 2021Various modern forms of chemical apparatus can find their origins in alchemical traditions, many of which have been attributed to the first century alchemist Maria the Jewess…
Presenter
North Dakota State University - DateMarch 22, 2022Silica-based glass is a very old material, with the technology of synthetic glass production thought to date back to ca. 3000 BCE…
Presenter
North Dakota State University - DateMarch 20, 2022Bioimaging is an essential tool used for disease monitoring, tumor diagnosis, and imaging-guided surgery. Of the various imaging modalities, fluorescence imaging allows for fast feedback and high sensitivity while being relatively inexpensive…

Speaker
North Dakota State University - DateMarch 21, 2022As the demand for new materials in organic electronic devices (photovoltaics, field effect transistors, etc.) continues to grow, the routes by which these materials are synthesized becomes increasingly important in order to maximize their utility…

North Dakota State University - DateMarch 22, 2022Indophenine, known since the late 1800’s, is an intensely colored blue dye consisting of a highly conjugated backbone. Applications of indophenines in organic materials have been limited, however, due to its low solubility and the difficulty in preparing isomerically pure species…

North Dakota State University - DateAugust 23, 2022Although the application of glass to chemical apparatus is thought to date to at least the first century CE, its initial use was severely limited due to the low chemical and thermal stability of early soda-lime glass…
Presenter
North Dakota State University - DateAugust 21, 2022For conjugated polymers, bandgap reduction is perhaps the most common target of molecular tuning, with the utilization of donor-acceptor (D-A) frameworks most often applied for the production of low bandgap (_Eg_ < 1.5 eV) and reduced bandgap (_Eg_ = 1.5-2.0 eV) polymers…

North Dakota State University - DateAugust 16, 2023While examples of organometallics species such as Cadet’s fuming arsenical liquid date back to the late 18th century, the term “organo-metallic” was introduced in 1852 by Edward Frankland (1825–1899), a professor of chemistry at the newly established Owen’s College in Manchester (now the University…
Presenter
North Dakota State University - DateAugust 14, 2023Ethyl alcohol, or ethanol, is one of the most ubiquitous chemical compounds in the history of the chemical sciences. The generation of alcohol via fermentation is also one of the oldest forms of chemical technology, with the production of fermented beverages predating the smelting of metals…
Presenter
North Dakota State University - DateMarch 18, 2024In the early period of the theory of valency, much difficulty was felt in explaining what were often called "molecular compounds", which are formed by the addition of species to molecules in which the valence was completely saturated…
Presenter
North Dakota State University - DateAugust 18, 2024The invention of laminated safety glass is attributed to the French chemist and artist Edouard Benedictus (1878-1930), who developed the innovation after inspiration stuck in the form of a fortuitous laboratory accident. As a result, he went on to develop what became known as Triplex safety glass…
Presenter
North Dakota State University - DateMarch 23, 2025The polymerization of monomeric species upon irradiation with light, commonly known as photopolymerization, is generally dated to the 1845 observation by John Blyth and August Hofmann that styrole (styrene) could be converted to metasytrol (polystyrene) by the action of light, while samples held in…
Presenter
North Dakota State University - DateAugust 20, 2025Although conjugated polymers are typically viewed as modern materials, the earliest examples of these polymers date back to 1834 with the polymerization of aniline by F. F. Runge…
