Direct band gap calculator is an iPhone application for calculating the direct band gap energy in ternary semiconductor alloys. Twelve different combinations are available. They are - AlInP, AlGaAs, AlInAs, AlGaSb, AlInSb, GaInP, GaInAs, GaInSb, GaPAs, GaAsSb, InPAs, InAsSb. You can adjust the doping percentage by using a slider interface and see the energy band gap value changes instantly. Values like Lattice Constant, Density, Dielectric constant, Effective mass electron, hole, Electron affinity, refractive index, Piezoelectric c...

EleMints is a revolutionary periodic table for the science geek in all of us. Boasting phenomenal retina graphics and features such as element properties, a molar mass calculator, a plot graph and much more, EleMints will inspire you to bring out your inner mad scientist. EleMints is structured within five sections, easily accessible from the bottom of the screen: • The Periodic Table can be shaded according to a particular property and zoomed for more information as desired. • The Graph displays property trends in a simple yet ...

Hydrogen! is an iOS app dedicated to the visualization of the atomic orbitals of the hydrogen atom as described by quantum mechanics. It is designed to be a tool for teachers and students who are already familiar with some quantum mechanical concepts, but anyone may appreciate the beauty of quantum mechanics! :) So, what does an atom look like? Well, it has a nucleus around which its electrons move just like planets around the sun, right? WRONG! :) In quantum mechanics we lose the classical concept of trajectory: not only we do...

Element Trek is an interactive Periodic Table of the Elements, augmented with animated 3D models of their electron orbitals and static 3D models of their crystal structures (see screenshots below) and a vast array of technical data, including 24 plot charts. Using the Bohr model, the electron shells and subshells are presented graphically with the ability to expand any atomic shell into its component subshells to see their electrons. You can click on any electron to show an interactive 3D model of its orbital. Additionally, there i...

Complete the electronic structure for the first 20 elements, and their associated ions, using Bohr-Rutherford diagrams and in number form. The app supports teaching and learning of chemistry at grade 9 or 10 level. In the UK, it supports the first section of the year 10 GCSE chemistry syllabus (UK). Also suitable for pupils in Y11 who are revising for GCSE chemistry or GCSE science exams. Add electrons into shells or energy levels by pressing on the screen where an electron is required. When enough electrons have been added...

How different are double and triple bonds from single bonds? And what do double-bonded molecules with multiple Lewis structures―such as ozone, nitric acid, and benzene―look like? ODYSSEY Multiple Bonds and Resonance is a visualization app that uses the results of rigorous quantum chemical calculations in order to fight pervasive misconceptions about molecular structure. Models of 51 simple molecules and ions are provided, both inorganic and organic. Each model can be manipulated in 3D with simple gestures. Bond lengths and bond an...

Where are the electrons? ODYSSEY Atomic Orbitals is a 3D visualization tool for one of the most widely taught topics in the introductory chemistry curriculum: What are the size, shape, and relative orientation of the atomic orbitals? How do these properties vary from element to element? What electron configuration corresponds to which set of orbitals? The answers are now available on your iPad with the tap of a finger—state-of-the-art visualization to make a difficult subject more accessible. ODYSSEY Atomic Orbitals provides visua...

Get ready! The Slimes are coming! You stand as the Commander of 34 types of Tiny Defenders against 26 varieties of persistent, aggressive but funny Slimes. With Colonel Khorn by your side what can go wrong? Why did the Slimes come? Are they Friends or Foe? That's for you to find out! They don't just slide across the screen, they can dig underground or attack you from above. You will encounter Yucky, Indy, Hopper, Blimp, Shinobi, Zeppelin, Slimebie and if you survive to reach the last level, B3 a.k.a Slimey! There's no hiding from t...
