Die deutsche Hafenstadt Hamburg
Published on Apr 10, 2012
Hamburg ist die größte Hafenstadt Deutschlands und eines der
beliebtesten Reiseziele der Deutschen.
Bereits seit dem Mittelalter ist Hamburg als Hafen- und Handelsstadt
weltbekannt.
Und auch heute bietet die Stadt architektonisch und kulturell viele Anreize
für Touristen.
漢堡是德國最大的海港城市，也是德國最吸引人的旅遊目的地之一。
從中世紀起，漢堡就是世界聞名的海港城市和貿易城市。
今天，漢堡仍然是以其建築和文化聞名的旅遊勝地。

Posted on June 29, 2014 by Harold Ambler
Antarctic sea ice has set a new all-time record maximum over the weekend of
June 28-29, 2014.
The sea ice surrounding Antarctica, which, as I reported in my book, has
been steadily increasing throughout the period of satellite measurement that
began in 1979, has hit a new all-time record high for areal coverage.
The new record anomaly for Southern Hemisphere sea ice, the ice encircling
the southernmost continent, ... 阅读全帖 |

发帖数: 53 | 3 "High Areal Density Nano-Engineered Magnetic Sensors: Application in
Information Storage Technology and Communications". The salary is $40,000
starting immediately.
Experience is required both in experimental synthesis of magnetic
nanoparticles and computation modeling of nanostructures. The university of
Louisiana has a 3-D visualization center (LITE) with state of the art
computational facility, probably one of the best in US.
Please reply to m*********[email protected] if your are interested. |

发帖数: 15 | 7 In self-assembly semiconductor quantum dots, the literal size is around
10~50 nm and height around 5~10 nm. But it's very difficult to measure
the exact dot size and shape experimentally. The areal dot density is
around 10^9 cm-2 to 10^11 cm-2, you can use this data to estimate the
average separation between different dots. I don't know electron diffusion
length, give me some clue.
The most common growth technique for QDs is the strain-driven self-
assembly technique. For example, the lattice co |
