| 20130143190 | HYDROGEN ATOM MODEL AS EDUCATIONAL TOOL - A hydrogen atom model has a drawing or three-dimensional model which expresses an electric field in a form of electric lines of force and a magnetic field in a form of magnetic lines of force, as an example. The electric field is obtained by a gradient vector operation applied to a wave function of a hydrogen atom and a sign inversion to the result of the vector operation. The magnetic field obtained by multiplication of the wave function by a θ-directed unit vector in polar coordinates (r, θ, φ) and application of a rotational vector operation to the result of the multiplication. | 06-06-2013 |
| 20140220533 | METHOD OF DISPLAYING ELECTROMAGNETIC FIELD IN HYDROGEN ATOM - The method assumes that a single solution or addition or subtraction of solutions of Schrodinger equation represented by polar or parabolic coordinates having its maximum value at the origin gives a wave function and an electric potential of a hydrogen atom. The method further: (1) regards the result of applying a gradient vector operation and thereafter a sign inversion to the wave function as an electric field; regards segments connected successively along the direction of the electric field as electric lines of force; and draws the electric lines of force so as to be approximately proportional in number to the percentage of the wave function with a difference between the maximum and minimum values of the wave function regarded as 100; and (2) displaying the wave function as an electric potential in a contour drawing. | 08-07-2014 |
| 20140370478 | Molecular modeling kit - The invention concerns a valence-electron-model in shape of a molecular-building-set and its use for early learning and teaching purposes at schools and universities. In the molecular-building-set each electron is preferentially enabled to form a chemical bond and is represented by a radical-neutral-connecting-element, each plus-charge is represented by plus-charge-connecting-elements and each minus-charge is represented by a minus-charge-connecting-element. Free electron-pairs are represented by two electron-representations in shape of an electron-pair-representation. Binding-forces between electron-pairs and basic-atomic-body-representations are represented by electron-pair-connecting-elements and basic-atomic-body-connecting-elements. Radical-neutral-connecting-elements are in a preferred embodiment shaped as radical-neutral-plugs with C3n-rotational-symmetry. Atomic-representations of each element have an individual characteristic set of electron-representations and the above named connecting-elements, which show the characteristic chemical properties of each individual element. Therefore it is for the first time possible to understand an atom or respectively an element as a unit with all its binding properties. Lewis-formula can directly be recognized and drawn of the represented molecules. | 12-18-2014 |
| 20150017624 | Molecular Modeling Device - A molecular modeling device that allows for the transformation of atoms in a tetrahedral bonding arrangement around a spherical central atom to a trigonal planar bonding arrangement, without the need for disassembly and reassembly and with using the same bonds, is disclosed herein. The present invention also provides visual representations of the empty, unhybridized p-orbital on a central atom. The present invention allows users to observe a transformation between sp2 and sp3 hybridizations of an atom. The molecular modeling device may be used in education, pharmaceutical, industrial, and other applications for improved conceptualization of the geometries and angles between atomic bonds. | 01-15-2015 |
| 20150079571 | Chemistry Instructional Material - An electronic device includes a display and a computer processor. The computer processor is configured to present to a user a first drawing of a cyclohexane ring in a first chair conformation and a second drawing of a cyclohexane ring in a second chair conformation. The first drawing of a cyclohexane ring displays a first bond in either an axial or equatorial position. The second chair conformation is different than the first chair conformation. The computer processor is further configured to receive a first input from the user for a carbon position of the first bond and an angular orientation of the first bond. The computer processor is also configured to indicate to the user whether the first input was correct or incorrect. | 03-19-2015 |
| 20150132734 | MOLECULAR MODELING SYSTEM INCLUDING MULTIPLE PI-BOND EXCLUSIONARY FEATURES - A molecular modeling kit provides a system for molecular modeling that represents exclusion between resonance structures in a molecule and permits their rotation, providing an informative tool for describing resonance in a classroom or other learning environment. The kit includes atom modeling components and bond connector components that are connected together to form models of molecules. The atom modeling components or the bond connector components include a mechanical exclusion feature that prevents simultaneous connection of two bond connector components to represent two pi-bonds formed with a single atom in a single plane. | 05-14-2015 |

| 20120202182 | HYDROGEN ATOM MODEL AS EDUCATIONAL TOOL - A hydrogen atom model is a three-dimensional model or planar drawing which expresses an electric field in a form of electric lines of force and a magnetic field in a form of magnetic lines of force. The electric field is obtained by a gradient vector operation applied to an electric potential and a sign inversion to the result of the vector operation. The electric potential is a wave function of any one of orbitals of a hydrogen atom. The magnetic field is obtained by a rotational vector operation applied to a vector potential. The vector potential is the wave function regarded as a vector potential having a component only in a θ-direction of polar coordinates (r, θ, φ). | 08-09-2012 |
