Sometimes you see a product and you’re like “Wow, that’s so futuristic.” Then you remember you’re living in 2017, 20 years after the date that a sentient AI wiped out most of humanity in the original Terminator movie, and you think: “Huh, maybe we’re living in the future already.” So it is with these amazing LED eyelashes.

Samsung Still The Top Maker Of Smartphone Displays In Q1
Samsung is still the number one top maker of smartphone displays in the first quarter of 2017, based on the market data released by industry tracker IHS Markit. One of the reasons for this remarkable performance is the company’s considerable growth in shipments of flexible organic light-emitting diodes or OLEDs. Samsung Display’s sales in the first quarter of 2017 amounted to more than $3.5 billion which represents 27.2 percent of the global market. Industry insiders believe that this overall growth is significant because this quarter is regarded as an “off-season” for the display industry. In keeping its top slot, Samsung Display has beaten Japan Display which only accounted for 17.8 percent of the international market. The third slot was taken by LG Display Co. while the fourth place went to BOE Technology Group of China.

Rohde & Schwarz slashes phase noise in RF signal generator
The result is a signal generator which can match higher output power and a spurious free dynamic range.
Designated the R&S SMA100B, which comes as a 6GHz instrument capable of generating up to 38dBm RF output power, or a 20GHz instrument generating up to 32dBm in the microwave frequency range.
Harmonic performance above 6GHz is specified at lower than 70dBc at 18dBm output power. Non-harmonics are below 110dBc at an output signal of 1GHz.
Wellington's future looks bright with 18,000 LED lights
It's going to be all white in the capital as the city prepares to switch to the more energy-efficient street lighting.
All 18,000 yellow sodium vapour lamps in Wellington could be replaced with new white light-emitting diode (LED) lights by next year, if the conversion is approved by Wellington City Council at its Annual Plan deliberations on Thursday.
The conversion would cost $15.2 million, but the council would share the cost with NZTA, which would provide all but $2.3m of the funding.
E Ink demos a foldable 10.2 inch display, among other things
E Ink is probably best known for making the paper-like electronic displays used in Kindle, Nook, and Kobo-style eBook readers. But the company also makes displays used for industrial and commercial products including digital signage and whiteboards.
Today the company announced that its E Ink Prism displays are now available in seven color options, allowing designers to build interactive displays into architecture.
And recently the company showed off a new foldable grayscale display that could be used for eBook readers that fold up… like a book.
Liquid tin-sulfur compound shows thermoelectric potential
Glass and steel makers produce large amounts of wasted heat energy at high temperatures, but solid-state thermoelectric devices that convert heat to electricity either don’t operate at high enough temperatures or cost so much that their use is limited to special applications such as spacecraft. MIT researchers have developed a liquid thermoelectric device with a molten compound of tin and sulfur that can efficiently convert waste heat to electricity, opening the way to affordably transforming waste heat to power at high temperatures.
Youyang Zhao, a graduate student in assistant professor of metallurgy Antoine Allanore’s research group, built a thermoelectric test cell that operates in a liquid state at temperatures from 950 to 1,074 degrees Celsius (1,742 to 1,965 degrees Fahrenheit). Commercial thermoelectric devices, based on materials such as solid-state bismuth telluride, operate at about 500 C, and a block of bismuth telluride costs in the neighborhood of 150 times more than tin sulfide per cubic meter.

Nitrades in transition
The average, everyday person might not be familiar with gallium nitride, also known as GaN, but there is a good chance they've heard of silicon, a semiconductor that's been used for decades and found in every computer and most electronics.
As a semiconductor, GaN is similar to silicon, but it differs in its elemental makeup and properties, which makes it a more robust, rugged type of electronic material. GaN's qualities allow it to operate at nearly five times higher power and temperature than silicon and commercial commodity semiconductors in certain applications.
Solid-state (or LED) lighting and wireless data transmitters for cell phone base stations are two examples where GaN has made a considerable impact over the past few years. Power switching components for solar inverters and electric vehicles are also moving towards GaN technology due to its ability to improve efficiency.
"GaN technology ultimately saves energy compared to incumbent technologies and can typically be packaged in smaller and lighter form factors," said Dr. David Meyer, U.S. Naval Research Laboratory (NRL) section head for wide bandgap materials and devices in the Electronics Science and Technology Division.
