Microencapsulation of friction modifiers for friction reduction in engines and machineries

Researchers at GW have developed new novel microencapsulation technology to encapsulate friction modifiers (FMs) (both organic and Mo-containing FMs) for automotive and diesel engines. The technology has several features: continuous additive release; triggered release; and slow continuous release + triggered release. The microcapsule size can be controlled...

Design and Fabrication Processes of Icephobic Surfaces

Researchers at GW have invented design and fabrication processes associated with the prevention of ice formation in various surfaces with a particular focus on surfaces associated with sea-ships, space-ships, high-altitude airplanes, and high-altitude aircrafts associated with space travel. One design invented is capable of delaying icing for at least...

Microencapsulation of Chemical Additives

There is a need for a new process for encapsulating complex chemical additives, where microcapsules can give strong performance under hostile chemical and mechanical conditions. While microencapsulation technique is a mature technology, microcapsule products made by traditional techniques may work well only in relatively simple, passive and non-hostile...

Self-Repairing and Self-Sustaining Autonomous Machines

Machines are subject to wear due to friction between moving parts. The expensive heavy equipment, such as wind turbines and aircraft propellers, are expensive to shut down or repair. Researchers at the George Washington University have developed a real-time sensor and nanotechnology-based system that detects the component surface damage in moving...

Friction Reduction for Engine Components

The demand for automobile energy efficiency and higher emission standards encourages the development of modern engines and drive trains that have lower frictional losses at various contact surfaces. One solution for reducing such frictional losses is to add texture modifications to engine/drive train surfaces that come in contact with one another during...

An Automated Cheating Detection System for Online Exams

Executive SummaryThe growth of online courses offered for credit heavily depends on innovations in the online proctoring industry to provide accurate, yet flexible remote examination. Current software-based online proctoring systems do not sufficiently monitor and inhibit cheating behavior in high stake online exams as they only rely on the narrow...
