Method Turns Trash Into GrapheneTBMG-3703706/01/2020
A new process turns bulk quantities of just about any carbon source into valuable graphene flakes. The “flash graphene” process can convert a ton of coal, food waste, or plastic into graphene for a fraction of the cost used by other bulk graphene-producing methods.

Q&A: Turning Trash into Valuable GrapheneTBMG-3687005/01/2020
James Tour, T. T. and W. F. Chao Chair in Chemistry; Professor of Computer Science, Materials Science, and NanoEngineering at Rice University, and his team have developed a process that will reduce the cost of manufacturing graphene by a factor of more than 100.

Space Debris Orbit and Attitude Prediction for Enhanced and Efficient Space Situational AwarenessTBMG-3302510/01/2018
This research deals with the problem of modelling the orbit and attitude motion of uncontrolled manmade objects in orbit about the Earth, which tumble due to the natural influences of the near-Earth space environment. A mathematical, physics-based and computational approach is taken to model the forces and torques that drive the orbit and attitude evolution of such objects. The main influence modelled is solar radiation pressure (SRP), which is the interaction of solar electromagnetic radiation with the surface of an object, leading to both forces and torques that influence the orbital and attitude motion. Other influences, such as the gravitational field of the Earth, are also modelled.

From Wastefulness to Competitiveness2007-01-290711/28/2007
The proposal of this paper is to deal with the waste elimination and the continuous improvement management in a productive process to guarantee the passport for the global competition to companies. From a systematic vision of the existing processes, the management of the continuous improvement is a must in all levels of the organization, considering the coordination of activities, the application of problems solving technique and its solution implementation up to the measurement of the achieved results. An efficient form to reduce costs and reach the competitiveness is the application of waste elimination by techniques, methodologies and qualification. The results of successful considered companies for being “Best-in-class” in profitability demonstrate that the success is directly related to processes in the business and therefore offer high quality products, in a short period of time with a relatively lower cost.
