Big particles are secret to crack-free paint (Jun 1)
http://physicsweb.org/article/news/11/6/1
The frustrating cracks that appear on newly painted surfaces could soon
be a thing of the past. Physicists in India have calculated how the
properties of paint, such as the size of the constituent particles,
affect its ability to stay smooth while drying, which could help
manufacturers to develop more effective crack-free paints (Phys. Rev.
Lett. 98 218302).
European X-ray laser gets the go ahead (Jun 5)
http://physicsweb.org/article/news/11/6/2
The building of a powerful new X-ray free-electron laser has been given
final approval by the German government now that sufficient funding has
been secured. The billion-Euro machine, known as XFEL, will be situated
in Hamburg, Germany and will enable researchers to observe chemical and
physical processes at the atomic level as they occur in real time.
Construction of the facility is set to start in early 2008 with an aim
to commence data collection in 2013.
LHC to skip low-energy test runs (Jun 6)
http://physicsweb.org/article/news/11/6/3
The Large Hadron Collider will not be ready in time to perform a
low-energy "engineering run", which was originally scheduled to take
place this November, according to an official at CERN. This will leave
the operators no chance to gain experience with the particle
accelerator's steering and detection systems before the high-energy runs
begin in spring next year. The delay is due primarily to the failure of
a Fermilab-built magnet during high-pressure tests in March.
Casimir force learns to swim (Jun 6)
http://physicsweb.org/article/news/11/6/4
Physicists in the US have shown that the Casimir force -- a mysterious
quantum phenomenon that draws nearby mirrors together -- can exist in a
fluid. The researchers found that two gold-plated surfaces submerged in
ethanol experienced the attraction when brought within 200 nm of each
other, albeit two times weaker than the force that would be found in a
vacuum. This could, they say, lead to a new "quantum floatation" effect,
which could be used to design better sensors
(arxiv.org/abs/0705.3793v1).
Wireless power a reality (Jun 7)
http://physicsweb.org/article/news/11/6/5
The mess of electrical cables that recharge our laptops, mobile phones
and PDAs could soon disappear altogether -- at least according to a team
of US physicists, who have shown how power can be transmitted without
wires using special "resonant" antennas. The researchers used the system
to power a 60-W light bulb placed two metres from a wireless
transmitter, and say that it could be scaled down for use in portable
devices without a loss of efficiency (Science Express doi:
10.1126/science.1143254).

Photon Counting with Silicon APD
Hamamatsu Photonics introduce the new multi-pixel photon counter (MPPC), the S10362-11 series, for photon counting applications. The device features brand new technology utilizing a Geiger-mode avalanche photodiode structure for ultra-low-level light detection and is supplied in a compact 5 mm package.
