Covalent Organic Frameworks Promise Huge Energy Storage Potential

Covalent Organic Frameworks Promise Huge Energy Storage Potential - RF Cafe"A powerful new material (COF) developed by Northwestern University chemist William Dichtel and his research team could one day speed up the charging process of electric cars and help increase their driving range. 'Our material combines the best of both worlds - the ability to store large amounts of electrical energy or charge, like a battery, and the ability to charge and discharge rapidly, like a supercapacitor ..."

Locating Your New Store

Locating Your New Store, April 1947 Radio News - RF CafeLocation, location, and location. Those are always half-jokingly cited as the most important three factors to consider when deciding where to best set up a retail business. Unfortunately, the days of scouting out a spot to set up an electronics sales and service shop are long gone. Except for a cellphone screen replacement service at a mall kiosk and maybe the Geek Squad desk at the Best Buy store, there are not many places left that do consumer electronics repair - at least as a primary vocation. This story makes a good read for anyone contemplating setting up shop where serving the local population is a prime objective ...

Analog DNA Circuit Does Math in a Test Tube

Analog DNA Circuit Does Math in a Test Tube - RF Cafe"Often described as the blueprint of life, DNA contains the instructions for making every living thing from a human to a house fly. But in recent decades, some researchers have been putting the letters of the genetic code to a different use: making tiny nanoscale computers. In a new study, a Duke University team led by professor John Reif created strands of synthetic DNA that, when mixed ..."

Where the Tech Jobs Are: 2016

Where the Tech Jobs Are: 2016 - RF Cafe"The Class of 2016 will enter the most welcoming U.S. job market in nearly a decade: 67% of employers say they plan to hire recent college graduates this year, the highest number since 2007, according to job site CareerBuilder's annual forecast. Second only to business majors, freshly minted engineers are set to enjoy most of that hiring goodwill as the U.S. economy continues its slow-but-steady post-recession growth. According to a survey conducted by the National Association of Colleges and Employers, at the end of last year, 2/3 of company respondents were planning to hire engineers ..."

NIST's Ampere Unit Definition Changes in 2018

NIST's Ampere Unit Definition Changes in 2018 - RF Cafe"Very soon the ampere - the SI base unit of electrical current - will take on an entirely new identity, and NIST scientists are at work on an innovative, quantum-based measurement system that will be consistent with the impending change. It won't be a minute too soon. The ampere (A) has long been a sort of metrological embarrassment embarrassment. For one thing, its 70-year-old formal definition, phrased as a hypothetical, cannot be physically realized as written ..."

Electrons at the Speed Limit

Electrons at the Speed Limit - RF Cafe"Speed may not be witchcraft, but it is the basis for technologies that often seem like magic. Modern computers, for instance, are as powerful as they are because tiny switches inside them steer electric currents in fractions of a billionth of a second. The incredible data flows of the Internet, on the other hand, are only possible because extremely fast electro-optic modulators can send information through fibre-optic cables in the shape of very short light pulses. Today's electronic circuits ..."

Radio Controlled Flight

Radio Controlled Flight, January 1947 Radio News - RF CafeEven though the U.S. Army Air Force and other research agencies around the world were at the forefront of experimenting with remote control airplanes, helicopters, and rockets, hobbyists were forging their own paths in the electronic art. I did not know until reading this article that drones were flown through the radiation field at the Bikini Atoll atom bomb test site for data collection. In fact amateur radio operators have long had the privilege of broadcasting for the purpose of remotely controlling a vehicle - the only scenario of Earth-based* transmission whereby the 'control operator' is not required ...

Petroleum engineers top the list once again at $98k. Electrical engineers can expect a mere $65k - same as our mechanical and sofware engineer brethren. Aerospace engineers will make a kilobuck less ...

This Crystal Could Change Laser Design

Crystal Change Laser Design - RF Cafe"Laser applications may benefit from crystal research by scientists at the National Institute of Standards and Technology (NIST) and China's Shandong University. They have discovered a potential way to sidestep longstanding difficulties with making the crystals that are a crucial part of laser technology. But the science behind their discovery has experts scratching their heads. The findings, published today in Science Advances, suggest that the relatively large crystals used ..."

What's Ahead for You in Engineering?

What's Ahead for You in Engineering?, July 1954 Air Trails - Airplanes and RocketsSaid Jimmy Stewart's character in "It's a Wonderful Life," George Bailey, "I'm shakin' the dust of this crummy little town off my feet and I'm gonna see the world. Italy, Greece, the Parthenon, the Colosseum. Then, I'm comin' back here to go to college and see what they know. And then I'm gonna build things. I'm gonna build airfields, I'm gonna build skyscrapers a hundred stories high, I'm gonna build bridges a mile long..."

The world was still a mystery to most people whose familiarity with foreign lands ...

Conducting Polymers Could be Used to Develop Soft, Flexible Electronic Devices

Conducting Polymers Could be Used to Develop Soft, Flexible Electronic Devices - RF Cafe"Polymer semiconductors, which can be processed on large-area and mechanically flexible substrates with low cost, are considered as one of the main components for future plastic electronics. However, they, especially n-type semiconducting polymers, currently lag behind inorganic counterparts in the charge carrier mobility – which characterizes ..."

Microsoft Excel Blamed for Gene Study Errors

Microsoft Excel Blamed for Gene Study Errors - RF CafeHere is an example of smart people doing dumb things and blaming it on anything other than themselves. I would be so embarrassed for being such a dummkopf who didn't understand a simple feature of the software, that I would never take it public and blame Microsoft. "Researchers trying to raise awareness of the issue claim that the spreadsheet software automatically converts the names of certain genes into dates. Gene symbols like SEPT2 (Septin 2) were found to be altered to 'September 2.' Microsoft said the gene renaming ..."
