[Perspective] Why the Pacific is cool

27.02.2015 | Ben B. Booth, Science , 2015

After a period of rapid global warming, the rate of global temperature rise has slowed markedly in the past 10 to 15 years. Is this “hiatus” a result of natural climate variability, or does it signify a change in the drivers of global warming? On page 988 of this issue, Steinman et al. (1) ...


[Editors' Choice] A temperature probe for the ultracold

13.02.2015 | Ian S. Osborne, Science , 2015

Author: Ian S. Osborne


[Report] Light-induced superconductivity using a photoactive electric double layer

13.02.2015 | Masayuki Suda; Reizo Kato; Hiroshi M. Yamamoto, Science , 2015

Electric double layers (EDLs) of ionic liquids have been used in superconducting field-effect transistors as nanogap capacitors. Because of the freezing of the ionic motion below ~200 kelvin, modulations of the carrier density have been limited to the high-temperature regime. Here we observe ...


[Perspective] Taking temperature at the nanoscale

06.02.2015 | Christian Colliex, Science , 2015

Measuring temperature has become commonplace since Fahrenheit, Celsius, and others introduced thermometers and temperature scales in the 18th century. However, the definition of temperature is not at all obvious, as it is now described as a statistical quantity given by the rate of change of ...


[Report] Nanoscale temperature mapping in operating microelectronic devices

06.02.2015 | Matthew Mecklenburg; William A. Hubbard; E. R. White; Rohan Dhall; Stephen B. Cronin; Shaul Aloni; B. C. Regan, Science , 2015

Modern microelectronic devices have nanoscale features that dissipate power nonuniformly, but fundamental physical limits frustrate efforts to detect the resulting temperature gradients. Contact thermometers disturb the temperature of a small system, while radiation thermometers struggle to beat ...


[Report] Programming colloidal phase transitions with DNA strand displacement

06.02.2015 | W. Benjamin Rogers; Vinothan N. Manoharan, Science , 2015

DNA-grafted nanoparticles have been called “programmable atom-equivalents”: Like atoms, they form three-dimensional crystals, but unlike atoms, the particles themselves carry information (the sequences of the grafted strands) that can be used to “program” the equilibrium crystal structures. We ...


[Report] High-efficiency solution-processed perovskite solar cells with millimeter-scale grains

30.01.2015 | Wanyi Nie; Hsinhan Tsai; Reza Asadpour; Jean-Christophe Blancon; Amanda J. Neukirch; Gautam Gupta; Jared J. Crochet; ..., Science , 2015

State-of-the-art photovoltaics use high-purity, large-area, wafer-scale single-crystalline semiconductors grown by sophisticated, high-temperature crystal growth processes. We demonstrate a solution-based hot-casting technique to grow continuous, pinhole-free thin films of organometallic ...


[Special Issue Report] Subsurface properties and early activity of comet 67P/Churyumov-Gerasimenko

23.01.2015 | Samuel Gulkis; Mark Allen; Paul von Allmen; Gerard Beaudin; Nicolas Biver; Dominique Bockelée-Morvan; Mathieu Choukr ..., Science , 2015

Heat transport and ice sublimation in comets are interrelated processes reflecting properties acquired at the time of formation and during subsequent evolution. The Microwave Instrument on the Rosetta Orbiter (MIRO) acquired maps of the subsurface temperature of comet 67P/Churyumov-Gerasimenko, ...


[Report] Tilt engineering of spontaneous polarization and magnetization above 300 K in a bulk layered perovskite

23.01.2015 | Michael J. Pitcher; Pranab Mandal; Matthew S. Dyer; Jonathan Alaria; Pavel Borisov; Hongjun Niu; John B. Claridge; M ..., Science , 2015

Crystalline materials that combine electrical polarization and magnetization could be advantageous in applications such as information storage, but these properties are usually considered to have incompatible chemical bonding and electronic requirements. Recent theoretical work on perovskite ...


[Report] Shock compression of stishovite and melting of silica at planetary interior conditions

23.01.2015 | M. Millot; N. Dubrovinskaia; A. Černok; S. Blaha; L. Dubrovinsky; D. G. Braun; P. M. Celliers; G. W. Collins; J. H. ..., Science , 2015

Deep inside planets, extreme density, pressure, and temperature strongly modify the properties of the constituent materials. In particular, how much heat solids can sustain before melting under pressure is key to determining a planet’s internal structure and evolution. We report laser-driven ...
