Do you find it hard to learn chemistry? Or is that you are someone who is looking to improve on their knowledge of chemistry? Or maybe someone who wants to work with the molecular structure in three dimensions. We have found 7 apps for you which will help you with your endeavors.

Self_Assembly By Cacciuto Group

Self Assembly is an iOS 4.2 or late compatible app that comes for FREE and is sized at 0.2 MB. With this app you get to design your own molecules and watch them self-assemble into complex two-dimensional structures. This simple and direct tool for nonscientist will let you experience the world of physical chemistry. You form interesting structures by manipulating the shape of the molecules, the concentration of the solution, and its temperature. You can then post your structures online in a flickr account.

The Elements: A Visual Exploration By Element Collection, Inc

The Elements is an iOS 3.2 or late compatible app that comes for $ 13.99 and is sized at 1.71 GB. This app is an ebook in which you get to read about all the elements in the periodic table and see photographs of their samples. These samples are freely rotatable and you can see them in stereo 3D using inexpensive 3D glasses. Amazing book that will keep you interested in chemistry for hours.

Periodic Table of the Elements By Kevin Neelands

Periodic Table of the Elements is an iOS 3.2 or later compatible app that comes for free and is sized at 0.2 MB. This app is a standard periodic table in which instead of cramming all the information for an element into one little square, you can select a chemical attribute and have the entire chart color coded to plainly show how the different elements vary with regard to the selected trait. You can select Atomic Number, Chemical Family, Electronegativity, Radioactivity, Melting Point, Boiling Point and State.

Molecules By Sunset Lake Software

Molecules is an iOS 3.2 or later compatible app that comes for free and is sized at 0.9 MB. This app supports English and French languages. With molecules you can view three-dimensional renderings of molecules and manipulate them using your fingers. You can also rotate the molecules, zoom in or out, or pan the molecule. You can view these structures in both ball-and-stick and spacefilling visualization modes.

Buffers By Akkyra Systems

Buffers is an iOS 3.1 or later compatible app that comes for $ 1.99 and is sized at 0.3 MB. With this app you can design buffer solutions for pH control. It can be useful both as a handy reference of available buffering agents and as an accurate, portable buffer calculator for chemical, biochemical and biological research. You can select from 40 commonly used buffering agents, generate accurate recipes covering broad pH, concentration and temperature ranges, access detailed information about each available buffer system and send your buffer recipes via e-mail.

Ball & Stick By MolySym, Inc.

Ball & Stick is an iOS 4.1 or later compatible app that comes for $ 2.99 and is sized at 1.6 MB. This is a molecular visualization app with highest quality graphics and has remote collaboration allowing two or more users to interact with the same molecule in real time. You also get independent representation control of each structure type (protein, ligand, water, and ions). You can rotate, translate, zoom, twist images about the Z-axis and save screen captures to the photos library. The performance has been optimized with smooth rotation even with the largest structures in the PDB. You can show your work on projector or external monitor and do a lot more with this app.

NIOSH Chemical Hazards By Random Support, LLC

NIOSH Chemical Hazards is an iOS 3.0 or later compatible app that comes for $ 2.99 and is sized at 6.7 MB. The app has the complete contents of the 2010 NIOSH pocket guide. It includes the enhanced functionality as you can search with Chemical Name/Synonym/Trade Name, CAS Number, RTECS, and UN / DOT Numbers. It also includes links to associated ICSC documents from the WHO as well as the latest (2008) associated DOT Emergency Response Guide pages. You can also select “Favorite” chemicals for quick access. It doesn’t require internet connection and supports printing of all guide pages as well as ERG and ICSC pages using iOS 4.2 AirPrint functionality.
