A new technique for creating films of barium titanate (BaTiO3) nano particles in a polymer matrix could allow fabrication of improved capacitors able to store twice as much energy as conventional devices. The improved capacitors could be used in consumer devices such as cellular telephones – and in defense applications requiring both high energy storage and rapid current discharge. This

Of all the criticisms of electric vehicles, probably the most commonly-heard is that their batteries take too long to recharge – after all, limited range wouldn’t be such a big deal if the cars could be juiced up while out and about, in just a few minutes. Well, while no one is promising anything, new batteries developed at the University

Nano Composite Material | Calculate High Cycle Fatigue | Repeated Mechanical Stress Create Stronger Nano Composites

009ec Inert rubbery polymer Composites

If someone does a lot of arm curls at the gym, the typical result is that the bones and muscles in their arms will get stronger. Recently, researchers at Houston’s Rice University inadvertently created a nano composite that behaves in the same way. Although the material doesn’t respond to static stress, repeated mechanical stress will cause it to become stiffer.

The introduction of Kinetic Energy Recovery Systems (KERS) is one of the most significant technical introductions for the Formula One Race. Formula One have always lived with an environmentally unfriendly image and have lost its relevance to road vehicle technology. This eventually led to the introduction of KERS. KERS is an energy saving device fitted to the engines to convert

How Fuel Cells Work

32824 01 how fuel cell works proton exchange membrane hydrogen fuel cell How Fuel Cell Works Automobile Engineering

An electrochemical reaction occurs between hydrogen and oxygen that converts chemical energy into electrical energy. Think of them as big batteries, but ones that only operate when fuel—in this case, pure hydrogen—is supplied to them. When it is, an electrochemical reaction takes place between the hydrogen and oxygen that directly converts chemical energy into electrical energy. Various types of fuel

Fuel Cell Stacks This is the heart of the hydrogen fuel cell car—the fuel cell stacks. Their maximum output is 86 kilowatts, or about 107 HP. Because hydrogen fuel cell stacks produce power without combustion, they can be up to twice as efficient as internal combustion engines. They also produce zero carbon dioxide and other pollutants.

A team of college students came together to design a new traffic intersection that transforms the power of footsteps into energy. The theories behind piezoelectricity, or the conversion of movements and vibrations into electricity, have existed for over 100 years. Very few applications of piezoelectricity exist in this modern age. Upon researching this technology, they immediately realized a multitude of
