Iran's efforts to block the internet have been in the news
lately. We will demonstrate the ability to transmit Persian text
by radio, bypassing the internet.

Doreen Bogdan-Martin, KD2JTX, is Elected as Next ITU Secretary
General

October 4, 2022

The International Telecommunication Union (ITU), the United
Nations specialized agency for information and communication
technologies, has announced the election of Doreen Bogdan-Martin
of the United States of America as the next ITU
Secretary-General. Bogdan-Martin will assume office on January 1,
2023. She is radio amateur; call sign KD2JTX.

The election took place during ITU's Plenipotentiary Conference
(PP-22) in Bucharest, Romania, on Thursday, September 29, 2022.
Bogdan-Martin won the position with 139 votes, out of 172 votes
cast by representatives of Member States.

"This is an exciting development for ITU," said International
Amateur Radio Union (IARU) President Tim Ellam, VE6SH. "...she
will be the first female SG [Secretary General] and only the
third to hold an amateur license. Doreen has an exciting agenda
for ITU."

"She will make an outstanding ITU Secretary-General and one IARU
will be proud to work with on behalf of the Amateur Services,"
said Ellam.

From New Atlas:

World's whitest paint is now thin enough to coat cars and planes

By Nick Lavars
October 03, 2022

Last year, engineers at Purdue University used their expertise in
materials science to produce the world's whitest paint, with an
ability to reflect around 98% of incoming sunlight and therefore
holds great potential when it comes to energy efficiency for
buildings. The team has now made some tweaks to the recipe and
produced a version that is thinner and lighter, which they say is
ideal for use on cars, trains and planes.

With a reflectivity of 98.1%, the material far exceeded the
reflectivity of commercially available heat-reflecting paints
that boast 80 to 90% reflectivity. In tests on outdoor surfaces,
the team found the paint could significantly lower their
temperature compared to the ambient surrounds and could
potentially produce cooling effects that are on par with common
air conditioners. But the paint did have its shortcomings.

"To achieve this level of radiative cooling below the ambient
temperature, we had to apply a layer of paint at least 400
microns thick," said Xiulin Ruan, who developed the paint.
"That's fine if you're painting a robust stationary structure,
like the roof of a building. But in applications that have
precise size and weight requirements, the paint needs to be
thinner and lighter."

So Ruan and his team came up with a new recipe. The new material
features boron nitride in hexagonal nanoplatelet form and offers
a solar reflectance of 97.9%, so a touch below the original, but
does so in layers of just 150 microns thick. This new paint is
not only thinner, but is also lower density and therefore weighs
around 80% less.

"This light weight opens the doors to all kinds of applications,"
said George Chiu, a Purdue professor of mechanical engineering.
"Now this paint has the potential to cool the exteriors of
airplanes, cars or trains. An airplane sitting on the tarmac on a
hot summer day won't have to run its air conditioning as hard to
cool the inside, saving large amounts of energy. Spacecraft also
have to be as light as possible, and this paint can be a part of
that."

The scientists say they are currently in discussions to
commercialize their paint and, having filed patents for the
technology, are enthusiastic about the possibilities.

"Using this paint will help cool surfaces and greatly reduce the
need for air conditioning," Ruan said. "This not only saves
money, but it reduces energy usage, which in turn reduces
greenhouse gas emissions. And unlike other cooling methods, this
paint radiates all the heat into deep space, which also directly
cools down our planet. It's pretty amazing that a paint can do
all that."

The research was published in the journal Cell Reports Physical
Science.
