Potent, environmentally friendly catalysts called Fe-TAML® activators, developed by scientists at Carnegie Mellon University, can destroy colored pollutants and toxic compounds resulting from paper and wood pulp processing.
The results of extensive field trials conducted by Carnegie Mellon University, Forest Research of New Zealand and the University of Auckland are being presented by Dr. L. James Wright of the University of Auckland on Wed., Sept. 10, in New York City at the 226th annual meeting of the American Chemical Society (paper 177, "Activation of hydrogen peroxide with a TAML® catalyst for wastewater remediation in the pulp and paper industry," Industrial & Engineering Chemistry Division).
"Right now, we can use Fe-TAMLs with hydrogen peroxide to clean up the unsightly color from chlorine-based bleaching processes used by mills to make paper and the chlorinated byproducts of those processes, which are considered a potential health hazard," said Terry Collins, the Thomas Lord Professor of Chemistry at Carnegie Mellon and the chief researcher on the Fe-TAML project. Collins describes the results of the decolorization as going from coffee to lemonade.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
