An Interactive Smith Chart
Smith is an instructional, interactive, menu driven program that offers the use of Smith Chart on a personal computer. Using the Smith Chart is greatly simplified by providing the user with a “tracking mode” in which the cursor is tracked, showing the normalized resistance and reactance as well as distances from source and load. Also, construction lines such as radius, diameter and circles can ...
متن کاملAlchemical derivatives of reaction energetics.
Based on molecular grand canonical ensemble density functional theory, we present a theoretical description of how reaction barriers and enthalpies change as atoms in the system are subjected to alchemical transformations, from one element into another. The change in the energy barrier for the umbrella inversion of ammonia is calculated along an alchemical path in which the molecule is transfor...
متن کاملFrancis Bacon: an Alchemical Odyssey through the Novum Organum
One of the most fascinating and thought-provoking periods in the history of chemistry is the coexistence in Western Europe of the ancient alchemy (having most likely arisen from Hellenistic and Arabic influences) and the rational, scientific chemistry we know today. By its own nature, this is a rather indeterminate period ranging from the Renaissance (around the 15 and 16 centuries) to early in...
متن کاملAlchemical Response Parameters from an Analytical Model of Molecular Binding
We present a parameterized analytical model of alchemical molecular binding. The model describes accurately the free energy profiles of linear single-decoupling alchemical binding free energy calculations. The parameters of the model, which are physically motivated, are obtained by fitting model predictions to numerical simulations. The validity of the model has been assessed on a set of host-g...
متن کاملAlchemical Properties of Colloidal Gold
The mystical metal has been used for both spiritual and medical purposes as far back as ancient Egypt. Over 5,000 years ago, the Egyptians used gold in dentistry and ingested it for mental, bodily, and spiritual purification. The ancients believed that gold in the body worked by stimulating the life force and raising the level of vibration on all levels. In Alexandria, alchemists developed a po...
