7 talks on the wonder of 3D printing
From ordering movie tickets to booking a dentist appointment, mobile and web apps have made the tasks of daily life easier. But there are some things that an app can’t do. Standing in line at the pharmacy is one of them. Lee Cronin: Print your own medicineIn today’s talk, Lee Cronin asks: “Could we make a really cool universal chemistry set? In essence, could we app chemistry?” With his team of researchers at the University of Glasgow, Cronin has created a 3D printing application that allows scientists to print out laboratory equipment specific to the experiment they wish to run — something they’ve called “reactionware.” At TED, we love sharing stories of 3D printing and its rapidly developing power to make new things possible.

SBU Team Discovers New Compounds that Challenge the Foundation of Chemistry - Stony Brook University Newsroom

The paper titled "Unexpected stable stoichiometries of sodium chlorides,” documents his predictions about, and experiments in, compressing sodium chloride—rock salt—to form new compounds. “I think this work is the beginning of a revolution in chemistry,” Oganov says. This opens all kinds of possibilities. To Oganov, impossible didn’t mean something absolute.
Plug-in Hybrids
Plug-in hybrids, sometimes called Plug-in Hybrid-Electric Vehicles (PHEVs), are hybrids with high-capacity batteries that can be charged by plugging them into an electrical outlet or charging station. They can store enough electricity from the power grid to significantly reduce their petroleum consumption under typical driving conditions. Different Kinds of Plug-in Hybrids There are two basic plug-in hybrid configurations: Series plug-in hybrids, also called Extended Range Electric Vehicles (EREVs). Plug-in hybrids also have different battery capacities, allowing some to travel farther on electricity than others. Benefits and Challenges The environmental benefits of plug-in hybrids and electric vehicles increase if they are powered by electricity from 'green' sources such as solar, wind or small-scale hydroelectricity.

Radioactive Decay Rates
Another example is the element Uranium-238 which has 54 more neutrons than its protons (Atomic umber =92). This element gains stability by passing through various types of decays (19 steps-- also known as the Uranium series) and is converted into Pb-206 (atomic number 82).For further information about different types of decay that Uranium goes through, refer to Decay Pathways). Decay Rates Due to the smaller size of the nucleus compared to the atom and the enormity of electromagnetic forces, it is impossible to predict radioactive decay. The atomic nucleus which is in the center of the atom is buffered by surrounding electrons and external conditions. or mathematically speaking A=λN where A is the Total activity and is the number of decays per unit time of a radioactive sample. Decay Rate & Chemical Kinetics Since the decay rate is dependent upon the number of radioactive atoms, in terms of chemical kinetics, one can say that radioactive decay is a first order reaction process. dNdt=−λN with
Solar vehicles and efficient vehicles
The Accelerated Composites Aptera will be produced as an all electric and as a plug in hybrid. Seating for two adults + an infant seat behind. Zero to 60 in 10 secs, top speed around 85 mph. While it is licensed as a motorcycle, they have put a lot of emphasis on safety including air bags and front, side, and rollover protection. Their goal is to offer the EV version in late 2008 and the hybrid version in late 2009 -- prices projected to start at $27K.

Plug-In Hybrid Retrofit Kit Could Greatly Improve Gas Millage For Only $3000
From Earth Techling's Nino Marchetti: The bright minds of young college students and their mentors are at work again in the world of green technology. This time around the scene is Middle Tennessee State University (MTSU) and the item being developed is a plug-in hybrid retrofit kit said to work with almost any car. Professor Charles Perry and a rotating group of MTSU students associated with the university’s Department of Engineering Technology have, for the last few years, been developing a wheel hub, plug-in hybrid retrofit kit. Perry’s wheel hub technology, according to MTSU, was recently outfitted on a 1994 Honda station wagon and helped this research vehicle to see a gas mileage increase anywhere from 50 to 100 percent. In a video which you can watch below, Perry describes how the technology works. The technology is designed for what would be around town usage. Also on HuffPost:
Turn Your Car Into a Plug-In Hybrid for $3,000 | Autopia
Photo: MTSU After five years of research, students at the University of Middle Tennessee have installed a full plug-in hybrid kit in a stock 1994 Honda Accord. The setup gives between 50 and 100 percent better gas mileage with two electric motors delivering power directly to the rear wheels, leaving the engine-powered front wheels to work with little effort. Energy for the motors comes from a lithium ion phosphate battery that sits in the trunk. The twin three-phase DC brushless motors sit in the empty interior around the rear brakes. Perry said, “The whole point was to demonstrate the feasibility of adding the electrical motor to the rear wheel of the car without changing the brakes, bearings, suspension — anything mechanical.” Perry says that the design is aimed at “around town” drivers, as range is limited to about 35 miles per charge, and once the car hits 40-plus mph, the system cuts off.
