Experiments at Berkeley Lab confirm that structural defects at the periphery are key in catalyst function

Defects and jagged surfaces at the edges of nanosized platinum and gold particles are key hot spots for chemical reactivity, a team of researchers working at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Hebrew University of Jerusalem in Israel confirmed with a unique infrared probe.

If you had told me ten years ago that I’d be a Ph.D. student studying solar energy technologies, I would have laughed in your face.

No, really. (more…)

Heat from Earth’s core could be underlying force in plate tectonics

By Guest PostMarch 5, 2017Sciencedavid rowley, east pacific rise, heat, mid ocean ridges, pacific subduction zones, plate dynamics, plate tectonics, underlying force

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. (more…)

Wissenschaftler zeigen, dass die Venusfliegenfalle Stickstoff-Verbindungen ihrer Beute zur Energiegewinnung einsetzt

Die Venusfliegenfalle fängt Insekten nicht nur, um an wertvolle Nährstoffe zu gelangen: Ein Forschungsteam um Prof. Dr. Heinz Rennenberg und Lukas Fasbender vom Institut für Forstwissenschaften der Universität Freiburg hat nachgewiesen, dass die fleischfressende Pflanze aus ihrer Beute auch Energie gewinnt. Die Wissenschaftlerinnen und Wissenschaftler haben ihre Ergebnisse im Fachjournal „New Phytologist“ vorgestellt.

A new standard in robotics

On the wall of Aaron Dollar’s office is a poster for R.U.R. (Rossum’s Universal Robots), the 1920 Czech play that gave us the word “robot.” The story ends with the nominal robots seizing control of the factory of their origin and then wiping out nearly all of humanity. Dollar, fortunately, has something more cheerful in mind for the future of human-robot relations. (more…)

Physicists gain insights into why materials break

Study of rigidity could help predict material failure, control cracking

New research suggests scientists could eventually help create materials that resist breaking or crack in a predictable fashion. (more…)

Forschungsnetzwerk veröffentlicht Empfehlung gegen “Lichtverschmutzung”

Lichterketten, Straßenlaternen und Werbe-Displays: Gerade im Dezember erhellen wir die dunkle Jahreszeit mit Außenbeleuchtung. Dass diese uns nicht nur in eine weihnachtliche Stimmung versetzt, sondern auch negative Folgen für Mensch und Natur haben kann, ist bereits länger bekannt. Ein internationales ForscherInnenteam mit Beteiligung von Thomas Posch, Astrophysiker an der Universität Wien, hat nun Leitlinien für die Außenbeleuchtung veröffentlicht. Diese sollen dazu beitragen, Licht in unseren Städten künftig nachhaltiger einzusetzen – zum Wohle von Mensch und Umwelt.

Geology professor’s study of olivine provides new data set for understanding plate tectonics

Plate tectonics, the idea that the surface of the Earth is made up of plates that move apart and come back together, has been used to explain the locations of volcanoes and earthquakes since the 1960s. (more…)
