In this study, the effect of benzenethiol ligand on CdSe/ZnS core/shell quantum dots was investigated. Conventional long-chain oleic acid (OA) and trioctylphosphine (TOP) capping ligands were partially replaced by short benzenethiol ligands, and the improvement in the luminescence performance was observed in quantum dot light emitting diodes (QD-LED). Approximately 1.8 fold improvement was achieved for both the maximum luminance and maximum current efficiency for the QD-LEDs fabricated with…

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what…

Supplemental information for “Colloidal Type-II CdS/ZnSe NCs : Synthesis, Electronic Structures, and Spectroscopic Properties” S.A. Ivanov, A. Piryatinski, J. Nanda, S. Tretiak, D. Werder, V. I. Klimov Theoretical model. To describe quantum states in a spherically symmetric Type-II core/shell nanocrystals (NC) characterized by the core radius R and the shell width H, we use effective mass approximation. We assume the existence of single energy bands for both electrons and holes. This assumption…

Created in 1981 by Hilary Putnam the Brain in a Vat theory is about a science fiction possibility of our brains quite literally being in a vat. Hilary Putnam uses referencing or representation, the Turing Test, the rules of language and a host of examples to establish that the statement “we are brains in a vat” is a self-refuting statement. He asks the question “Could we, if we were brains in a vat in this way, say or think that we were?” (Putnam 1981, p7) and comes to the conclusion that we…

Electron microscope (Manning, n.d.) is the instrument used to magnify different scientific artifacts with the used of electron beams to create the illustration of the sample, and has the capacity to magnify two million times of the original specimen. The development of the electron microscope was first known in the year 1931 because Ernst Ruska and Maximoll Knoll magnified electron image successfully, but the equipment was actually constructed in 1933 (Innes, n.d.). The concept of the electron…

of co-presence in the light of physics, mathematics, and cosmology, he appeals to the examples of non-Hausdorff manifolds and Cantor’s threefold concept of the finite, the transfinite, and the infinite in mathematics and to the non-locality of quantum mechanics. Thereby, he renders co-presence as an infinite fractal-like character. To be more specific, gleaning from Pannenberg the idea of the dialectical mutual indwelling of the finite and the infinite, based on Hegel’s concept of…

Plot of the Movie A Beautiful Mind is a biographical movie shot in 2001 by an American director Ron Howard. It is based on the story of the American mathematician John Nash, who was a Nobel Prize Laureate in Economics. The main actor Russell Crowe, starring as the professor J. Nash, is the promising scientist that demonstrates success in mathematics. He wins the famous scholarship at Princeton University (Lee, 2009), where he creates interesting concepts. Meanwhile, Nash starts working for the…

In the chapter “Democritus, Sophie is asked “Why is Lego the most ingenious toy in the world?”(Gaarder 44). This question then leads to the philosopher, Democritus, who is known for the atom theory. Alike the structure of legos, he believed all atoms that made up the universe were “eternal, immutable, and indivisible”(Gaarder 45). Furthermore, Democritus believed all atoms were firm and solid and were all different. Since they were all different, he thought they could join together and form all…

“Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.” Albert Einstein, a specialist on developing general theories and determined scientist. This quote connects to a time in my life when I was eight years old and I found something that I really loved. But it appeared extremely hard. It was to become an artist and I had big dreams of becoming fantastic at my new hobby of art, but how would I be as good as my role model, Lainey?…

Science Fair 2018- Rock and Roll Bounce Observation What is friction? What is the difference between motion and forces? Are there different types of motions and forces? What is gravity? What is Newtons law? Does friction have to do with motion or force? Does Newton's law apply to everything that is moving? How is movement and forces apply to the world itself? Do natural disasters involve motion and forces? Does energy have to do with motion and forces? How many types of…
