The U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality. Hydrogen and fuel cells have the potential to offer a broad range of benefits for the environment, the economy and energy security. Safety is an essential element for establishing public confidence and reducing barriers toward the...

The Official Canadian Hydrogen Convention Mobile App The Canadian Hydrogen Convention Mobile App is the official platform for all participants to navigate their event experience. Participants are able to quickly and easily connect with visitors, delegates, exhibitors, speakers, and more. Attendees enjoyed a seamless and innovative digital experience for connecting people to create meaningful relationships.

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...

Atom in a Box is an aid for visualizing the Hydrogenic atomic orbitals, the three-dimensional states that the electron occupies in Hydrogen, a prime and otherwise unwieldy example of Quantum Mechanics. It interactively shows what the Hydrogen atom "looks" like. Unique among visualizations of Quantum Mechanics, it uses highly optimized code to perform 3D volumetric raytracing through the electron wavefunction's probability density and presents its results in real-time. It animates and mathematically describes all 140 eigenstates up ...

Rewritten from scratch for the iPad, Atom in a Box HD is an aid for visualizing the Hydrogen atomic orbitals, the three-dimensional states that the electron occupies in Hydrogen, a prime and otherwise unwieldy example of Quantum Mechanics. It interactively shows, in an immersive environment, what the Hydrogen atom "looks" like. Unique among visualizations of Quantum Mechanics, it uses highly optimized code to perform 3D volumetric raytracing through the electron wavefunction's probability density and presents its results in real-ti...

Would you like to have fun, while testing your knowledge of Physics. Would you like to strengthen and reinforce your understanding of concepts, ideas, people and facts of Physics. Are you a student, teacher or just curious about Physics. Then, this game on Physics is for you. The objective of the game is to use the shortest number of steps possible to get to an end concept from a starting concept. Sounds simple enough… but is it really that easy, give it a try. At each stage, you will be offered a set of choices, select the one t...

Pipe Flow GasRef is a gas properties calculator app that calculates the Density, Z Compressibility Factor, Viscosity and Specific Heat Ratio (SHR) at different temperature and pressure conditions for a number of common gases: Air, Ammonia, Argon, Butane, Butene, Carbon Dioxide, Carbon Monoxide, Dimethylether, Ethane, Ethylene, Helium, Hydrogen, Hydrogen Sulfide, Isobutane, Krypton, Methane, Nitrogen, Nitrous Oxide, Oxygen, Propane, Propylene, R125, R134a, R23, R32, Sulphur Dioxide, and Xenon. Developed by Pipe Flow Software, the...

Chemistry is, ostensibly, all about molecules. However, molecules never exist in isolation—molecules interact! Use this app to gain greater familiarity with the fundamental concepts of intermolecular forces and experience their actions at the molecular level. Dispersion interactions, dipole-dipole interactions, and hydrogen bonding are all explored with the help of more than 50 molecular models. A number of prototypical compounds, such as methane, hydrogen cyanide, and water are first presented at the level of quantum chemistry b...

In 2050, the 3rd World war occurred after North KR had provoked the arms race on thermonuclear hydrogen bomb since 2016. Soon after that, the hydrogen bomb technology had fallen into the hands of terrorist organizations leading the earth to elimination disaster. The thermonuclear weapons caused radioactive pollution all over the world. It came with climate change making the earth's temperature rise uncontrollably. As a result, the sea and all water sources had disappeared completely, all animals and plants were on the edge of ex...
