 "Researchers have developed the world's first
complementary electrochemical logic circuits that can function stably for long periods
in water. This is a highly significant breakthrough in the development of
bioelectronics. The first printable organic electrochemical transistors
were presented by researchers at LiU as early as 2002, and research since then
has progressed rapidly. Several organic electronic components, such as
light-emitting diodes and electrochromic displays, are already commercially
available. The dominating material used until now has been PEDOT:PSS, which is a
p-type material, in which..."
 EIRP - effective isotropic radiated power - is
an important parameter when calculating both intentional and unintentional electromagnetic
emissions. EIRP is a vector quantity that accounts for both power (magnitude) and 3-dimensional
coordinates (direction). It includes antenna directivity that concentrates power in a
particular direction rather than distributing it equally in all directions (e.g., isotropically).
Effective radiated power factors in modulation type and power envelope shape
as well. Knowing how to measure that quantities can make the difference
between...
It
is with immense pride and excitement that I write to inform you of the next chapter for
Peregrine Semiconductor and Murata. Effective today, 17 January 2018, Peregrine will
operate under a new name, pSemi Corporation.
pSemi will have the same experienced leadership team, but we will have a broader scope
and an expanded product portfolio. When Murata acquired Peregrine in Deceember
2014, they kept the Peregrine brand name untouched. In the last few years,
Murata has asked our team to extend our reach, increase our intellectual
property...

 "You don't have to be perfectly organized to pull
off a wave, according to scientists. Using a set of gyroscopes linked together, physicists
explored the behavior of a material whose structure is arranged randomly, instead of
an orderly lattice. They found they could set off one-way ripples around the edges, much
like spectators in a sports arena - a 'topological wave,' characteristic of a particularly
unusual state of matter. Using a set of
gyroscopes
linked together, physicists explored the behavior of a material whose structure
is arranged randomly, instead of an orderly lattice. They found they could set

environmental sensors. The sensors are carefully selected to enable customers to
build complete sensor nodes by just adding the sensor, an antenna...
 As with most technologies that have been around
for decades, the fundamentals of
crystal filters have not changed with time. Materials and methods have changed, of
course, but the equivalent lumped element model (using resistors, capacitors and inductors)
of a crystal filter is essentially the same today as it was in 1969 when this article
appeared in Electronics World magazine. Open a first semester
electronics circuits textbook and the chapter on crystals will look much like
this piece by Mr. Robert Kent, of Damon Engineering. The use of crystal had a
profound impact on filter design because their extremely high "Q" factors...

37 modules such for $29. You can also get application-specific Arduino
kits like this one for
RFID development or for a
smart robotic car. There's no time like the present to get started.
 Did you know that Mallory, the well-known capacitor
maker, at one time was at the forefront of solid state rectifier diodes? Not me, at least
before seeing this infomercial from a 1969 Electronics World magazine. I
know that they made selenium rectifiers that replaced many application which formerly
required vacuum tubes. This installation of Mallory's "Tips
for Technicians" is one of many run for the benefit of service shop guys who needed
to keep abreast of changes in technology. Note the admonition at the end: "Don't forget
to ask 'em - 'What else needs fixing?'"...

 "Residents of southeast Michigan were left a bit
shaken Tuesday night after a big bright flash lit up the sky and the ground beneath them
shook. A flying saucer? No. A shooting star? Not quite. The National Weather Service
eventually solved the mystery, tweeting 'USGS confirms
meteor occurred around 8:10 pm, causing a magnitude 2.0 earthquake.'"
The science-challenged reporter (as are most) got the part about it not being a shooting
star wrong, though. A 'shooting
star' is a meteor, although it is not a star...
 "A year-long operating event, 'Science Milestones in the History of Radio,' is under way, sponsored
by the Italian Amateur Radio Association (ARI) Fidenza Radio Club. Each month

 "Intel has passed a key milestone while running
alongside Google and IBM in the marathon to build quantum computing systems. The tech
giant has unveiled a superconducting quantum test chip with
49 qubits: enough qubits to possibly enable quantum computing that
begins to exceed the practical limits of modern classical computers. Intel's announcement
about the design and fabrication of its new 49-qubit superconducting quantum chip, code-named
Tangle Lake, came during a keynote speech by Brian Krzanich, Intel's CEO,

 Prior to the big push for leadless solder in the
1990s, probably 99% or more of the solder used by industry, tradesmen, and hobbyists
contained lead. The
60/40 Sn-Pb (and 63/47) alloy, both with and without a rosin or acid core,
was used for electrical work, electronics, plumbing, copper guttering,
radiators, and many mechanical assemblies made of steel, brass, copper, tin,
etc. Between World War I, "The War to [Not] End All Wars," and World War II, the
electronics industry exploded in growth. All realms of society and government
became utterly dependent on products assembled using solder. Both tin and lead
were abundantly available...
 "In a paper titled 'Deterministic Line-Shape Programming
of Silicon Nanowires for Extremely Stretchable Springs and Electronics' published in
the Nano Letters, an international team of researchers from Nanjing University, Peking
University, and CNRS-Ecole Polytechnique has demonstrated a new route to
designing silicon-based flexible electronics in a scalable way. Rather than
starting from Si wafers cut-out from drawn silicon ingots, they describe in
their paper a nanoscale-version of the crystal-pulling methods used to grow
silicon..."

 "China has been leading the world in construction
of solar energy plants, building dozens of new solar farms over the past few years. In
addition to building standard solar farms, the country has also been experimenting with
more innovative ways to draw energy from the sun. Recently, the city of Jinan built China's
very first
solar road,
which lasted about a week until someone stole it. The road opened on December
28, and on January 2 an inspection team noticed a piece of the road was missing.
The piece was small, measuring only 6 inches wide..."
 According to author R.R. Freeland,
manufacturing processes for radio-quality manmade crystals saw major
improvements toward the end of World War II. At the time, the process was highly
manual-intensive, as can be seen in this really nicely done 1940s video titled
"Crystals Go to War." Prior to the use of crystals as frequency-determining
devices, inductor-capacitor (LC) tank circuits were the dominant configuration.
There were actually other frequency-determining schemes like spark gaps and even
vibrating mechanical reeds. As you might guess, anything less than...

 Nuclear energy was a big topic in the
1960s and 1970s as it was believed to be the future of electrical power
generation for the world (at least up until the 3 Mile Island and Chernobyl
incidents occurred). Ships and submarines were being powered by reactors that
allowed them to run for months at a time without refueling, atmospheric
emissions were practically zero, and the fuel source was abundant (albeit not
simple to obtain). Medical and space applications were increasingly dependent on
a greater knowledge of radiation and its effects on humans, plants, animals, and
electronics. Many people by that...
