SCIENTISTS ANNOUNCE KEY TO SMALLER CAPACITORS

STEPHEN/ANCHOR: Physicists in Europe say they have found a key to 
creating smaller capacitors for electronics. Kevin Trotman, N5PRE, has 
that report.

KEVIN: Researchers believe they have found a means of building smaller 
capacitors, allowing for some electronic devices to be greatly 
miniaturized. The IEEE Spectrum reports that scientists are saying 
these capacitors could even be as small as one-hundredth the size of 
many of the ones presently in use. They are creating them with 
materials they call superlattices and they are made from materials that 
mimic antiferroelectrics. Antiferroelectrics are important because they 
have positive and negative poles -- electric dipoles -- pointed in 
opposing directions, creating zero electric polarization. Exposed to an 
electric field having sufficient strength, antiferroelectrics can 
become highly polarized, which results in the large energy densities 
needed.

Because there are few antiferrelectric materials that occur naturally, 
scientists have created and used artificial ones and report in the 
Journal, Science, that their work with the superlattices shows promise 
for working on a much smaller scale: their ability for energy storing 
is 100 times greater than conventional capacitors. Physicists believe 
they will someday be used to create these ultra-tiny capacitors.

Physicist Hugo Aramberri of the Luxembourg Institute of Science and 
Technology said: [quote]: "It would be interesting to measure other 
properties, like how much voltage they can withstand, their endurance 
in long-term use, and ultimately commercial viability." [endquote]

WORLD OF DX

In the World of DX, be listening for Fred, DL5YM, and his XYL Tina, 
DL5YL, operating as HB0/DL5YM and HB0/DL5YL, respectively, from 
Lichtenstein between September 7th and 27th. They will hike during the 
daytime and later operate on 160-6 metres using mostly CW, with some 
SSB and RTTY. You may also hear them in the CQWW DX RTTY Contest on 
September 24th and 25th. QSL via their home callsigns, direct, via the 
DARC Bureau or ClubLog.

Be listening for Giuseppe, IK5WWA, operating as IM0M (Eye Em Zero Em) 
from La Maddalena between September 1st and 13th on various HF bands 
plus 6 metres. He will also participate in the I.I.A. Italian Island 
Award. Send QSLs to his home callsign, via the bureau or direct.

Alex, AK4AM, will be active as AK4AM/p from Atlantic Beach, Bogue Banks 
off the coast of North Carolina between September 2nd and 6th. This is 
IOTA NA-112. Alex will be on 160 metres through 6 metres. Additional 
details are available on QRZ.com. QSL via LoTW.

Satoshi, JH2EUV, can be heard on the air from Timor-Leste (OC-148) as 
4W/JH2EUV. He is operating on 10, 12 and 15m FT8. It is unclear how 
long his stay will be. QSL via LoTW or the bureau.

Be listening for Harald, DF2WO, operating from Burkina Faso as XT2AW 
from September 4th to the 18th.  He will be on the HF bands using CW, 
SSB and the digital modes. He will also be using the QO-100 satellite. 
QSL via QRZ.com instructions. 

Here's a reminder too, for the weekend of the 20th and 21st of August. 
It's the 25th annual International Lighthouse and Lightship Weekend. 
With 360 lighthouses around the world registered at the time of writing 
to take part in this event they will be active across the HF and VHF 
bands on all modes. This is not a contest so call and have a chat! Full 
details at ILLW dot NET.
