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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
