Cesium atoms shaken, not stirred, to create elusive excitation in superfluid

Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like a fountain.

Future Nobel laureate Lev Landau came along in 1941, predicting that superfluid helium-4 should contain an exotic, particle-like excitation called a roton. But scientists, including Landau, Nobel laureate Richard Feynman and Wolf Prize recipient Philippe Nozières have debated what structure the roton would take ever since. (more…)

China’s Hidden Water Footprint

COLLEGE PARK, Md. – Highly developed but water-scarce regions in China, such as Shanghai, Beijing, and Tianjin, are contributing to water depletion in other water-scarce regions of the country through imports of food, textile, and other water intensive products, according to a new study published in the journal Environmental Science & Technology. For example, purchasing cloth in Shanghai may not consume water directly, but the production of cloth requires cotton, which is water intensive to cultivate – indirectly contributing to the water scarcity in the less-developed cotton production regions. This dynamic also holds true for food and other products. Only 20% of Shanghai’s scarce water footprint, or the amount of scarce water consumed, is from local watersheds while 80% is from water resources of other water-scarce regions, such as Xinjiang, Hebei, and Inner Mongolia.

Im Raucherparadies China beginnt ein Umdenken

Was für Europäer oder Amerikaner selbstverständlich ist, können Chinesinnen und Chinesen kaum verstehen: Rauchfreie Zonen.

Das grösste Raucherparadies östlich von Österreich ist ohne Zweifel die Volksrepublik China, neben Brasilien die süchtigste Rauchernation der Welt. Die Tabakindustrie sieht die wachsenden Umsatzzahlen im Reich der Mitte – klammheimlich, versteht sich – mit Wohlgefallen. Nach amtlichen Angaben wurden im letzten Jahrzehnt in China fast fünfzig Prozent mehr Zigaretten produziert. Weniger erfreut, ja entsetzt, sind die Gesundheitsbehörden, denn Chinesinnen und Chinesen bezahlen einen hohen Preis. (more…)

Die Revolution des Kleinen Prinzen

Parteichef Xi Jinping hat zehn Jahre Zeit, seine ehrgeizigen Reformziele zu verwirklichen. Zum Wohl Chinas und der Welt.

Kaum vom 3. Plenum des 18. Zentralkomitees der KP im November verabschiedet, nehmen die chinesischen Reformen langsam Gestalt an. Chinesische Kommentatoren vergleichen schon jetzt 3/18 mit 3/11. Hinter den in China beliebten Kurzformeln verbirgt sich stets Wichtiges. Am 3. Plenum des 11. Parteitages nämlich setzte im Dezember 1978 der grosse Revolutionär und Reformer Deng Xiaoping die Wirtschafts-Reform in Bewegung. Dies nach dreissig Jahren Maoismus, einer grossen Hungersnot 1958-69 (45 Millionen Tote), der Katastrophe der Grossen Proletarischen Kulturrevolution 1966-76, nach einer Zeit allgemeiner, kollektivierter und egalitärer Armut. Der Rest ist Geschichte. (more…)

Stretchable energy sources

UD researchers develop stretchable wire-shaped supercapacitor

Advances in flexible and stretchable electronics have prompted researchers to explore ways to create stretchable supercapacitors — robust energy storage devices — to power these and other devices. 

Supercapacitors offer significant advantages over common batteries, including the ability to recharge in seconds, exceptionally long life span and high reliability, leading to their incorporation in portable consumer electronics, memory backup devices, hybrid vehicles and even large industrial scale power and energy management systems.

Do academic rankings create inequality?

A study led by a Michigan State University scholar questions whether higher education ranking systems are creating competition simply for the sake of competition at a time when universities are struggling financially.

Global rankings that emphasize science and technology research – such as the Academic Rankings of World Universities by Shanghai Jiao Tong University – have become increasingly popular and influential during the past decade, said Brendan Cantwell, lead author and assistant professor of educational administration.

Physicists Demonstrate the Acceleration of Electrons by a Laser in a Vacuum

Accelerating a free electron with a laser has been a longtime goal of solid-state physicists.

David Cline, a distinguished professor in the UCLA Department of Physics and Astronomy, and Xiaoping Ding, an assistant researcher at UCLA, have conducted research at Brookhaven National Laboratory in New York and have established that an electron beam can be accelerated by a laser in free space.

This has never been done before at high energies and represents a significant breakthrough, Cline said, adding that it also may have implications for fusion as a new energy source. (more…)
