Molecular Engineering for Mechanically Resilient and Stretchable Electronic Polymers and Composites

The ability to predict the mechanical properties of organic semiconductors is of critical importance for roll-to-roll production and thermomechanical reliability of organic electronic devices. This research describes the use of coarse-grained molecular dynamics simulations to predict the density, tensile modulus, Poisson ratio, and glass transition temperature for poly(3-hexylthiophene) (P3HT) and its blend with C60. In particular, it is shown that the resolution of the coarse-grained model has a strong effect on the predicted properties.

Reducing the High Cost Of Titanium

Titanium is neither a precious metal nor rare, yet among industrial metals it has the reputation for being very expensive. It's the fourth most abundant metallic element and the ninth most abundant of all the elements in the earth's crust. Its commercially useful oxide ore occurs in the minerals rutile and ilmenite and numerous iron ores, and exploitable ore deposits are liberally scattered around the world in Australia, Canada, India, Malaysia, Norway, Russia, South Africa and the U.S. But due to its properties and high cost it has often been referred to as unobtanium.

Engineered Solutions for Enclosure Sealing and Insulation

In the aerospace and defense industries, enclosure sealing and insulation needs to meet challenging and complex requirements. For example, the EMI gaskets that are used in military touchscreens must shield sensitive electronics from electromagnetic interference (EMI) while providing electrical conductivity and ensuring environmental sealing. These enclosure gaskets must also cushion the unit from mechanical shock and avoid interfering with the display's touch function.

Electrodeposition of Metal Matrix Composites and Materials Characterization for Thin-Film Solar Cells

The current trend in both space and terrestrial photovoltaics is to implement high-efficiency, thin-film-based solar cells to reduce weight and materials cost while improving performance. For space photovoltaics, multi-junction (MJ) solar cells have been used almost exclusively due to their high efficiency and high radiation hardness. The efficiency of state-of-practice triple-junction (TJ) cells used in space today is approximately 30% under 1-sun Air Mass 0 (AM0) spectrum.

The Three Rs of Analog Position Sensor-Based Mechanical Measurements

Those of us old enough to remember the “good old days” recall that grade school focused on learning the 3 R's: reading, ‘riting, and ‘rithametic. In the world of sensors, there are also 3 R's: Repeatability, Resolution, and Response. As important as these sensor parameters are, there is often confusion in the mind of users about exactly what they mean and in what ways they tend to interact with each other. This article will attempt to explain the 3 R's for position sensors and dispel any confusion that might exist.

Air Force Invents Aircraft Tire Change Tool

How many airmen does it take to change a cargo aircraft tire? Too many. The U. S. Air Force’s largest aircraft, the C-5M Super Galaxy, has 28 tires. The current tire changing method is performed several times a week. It is a complicated, multistep procedure that requires up to five people working together for an extended period of time with a number of safety risks due to the size and weight of the tires and tools.
