Nanoclay Modification and Compound Formulation for Foaming Linear Polypropylene

Linear polypropylene is not ideal for making foams for sealing purposes due to poor melt strength. The attempts to overcome this limitation by cross-linking a portion of the linear polymer or by adding a long chained branched polymer have resulted in unwanted side effects, such as a reduction in recyclability. Additionally, long chain branched ...

070121: Conductive Sheet Molding Compound with Carbon Based Nanomaterials

Graphite is a layered material and the stiffest material found in nature--significantly higher than clay that could be displaced by this invention in related applications. Graphite has excellent electrical and thermal conductivity. MSU has developed an inexpensive process to produce exfoliated graphite nanoplatelets (xGnP) which when added to p...

070073: Efficient Selection of Carbon Nanotubes by Desired Properties

In the beginning powder form, carbon nanotubes (CNTs) have a wide range of physical dimensions and electrical properties at the level of individual CNTs. A number of researchers have tried various methods of selecting and manipulating (CNTs) produced in batch quantities. However, these processes do not select CNTs by specific dimensions, or sel...

050123: A Reliable Process for Fabricating Single Nanowires and Nanotubes

In a broad class of future nano-devices, a key challenge will be to construct connections between electrodes using single carbon nanotubes (CNTs) or semiconductor nanowires (NWs). Current methods have major difficulties with repeatability and the ability to eliminate uncertainties. A major problem is that growing NWs or CNTs across an electrode...

050122: Pneumatic Nano-Probe Tip for Nano-Manipulation and Manufacturing

A major problem with nano-manipulation is holding the target. Due to the lack of micro force/flow feedback, the target is often destroyed during its manipulation. It would be highly desirable to have a means for picking up and releasing nano-objects without the above difficulties. Description The current invention addresses current operational ...

050008: Nano-layered Silicates with High Chemical Reactivity

The smectite family of layered silicate minerals, the so-called "swelling clays," have theoretical surface areas of 700 meters per gram or larger. However, accessing this surface area for important materials applications such as catalysis, adsorption, and polymer-clay nanocomposite formation is not readily achievable; the elementary one-nanomet...

030073: Improved Force Sensing on Nano-Manipulated Objects

Efficient manipulation of nano-sized objects will require an effective means for sensing the force exerted by a nanoprobe on the object. Current PZT (lead zirconium titante)-based piezoelectric force sensors are limited in their sensitivity. Description By using a highly sensitive polyvinylidene fluoride (PVDF) piezoelectric force sensor to mea...

030062: Composite metal Matrix Castings and Solder Compositions and Methods for Microelectronics and Metal Matrix Castings

The rapid advance in the miniaturization of electronic components require novel soldering solutions with sub-micron reinforcements. Sub-micron reinforcements can minimize grain boundary sliding. Another challenge is increased current density in Micro-Electro-Mechanical Systems (MEMS). Ion migration across electrodes causes voids and ultimately ...
