Generating electricity is not the only way to turn sunlight into energy we can use on demand. In a study published last week in the journal Science, Choi and postdoctoral researcher Tae Woo Kim combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.
Earlier this month, NJIT formalized an agreement with Chinese partners that will advance the university's research on thin-film solar cells, an alternative energy technology with the potential to make buildings and other infrastructure substantially more energy-efficient.
The University of Tennessee, Knoxville, will be part of a national effort, announced today by President Barack Obama, which could lead to more fuel-efficient cars and decreased costs for ships and aircraft. Suresh Babu and a team of faculty will help lead UT's research effort in the $140 million Detroit-based institute....
A study was recently released by North Carolina State University that provides evidence supporting the fact that electric drive vehicles (EDVs) have little impact on reducing emissions. As an engineering audience that knows efficiency when they see it, most PD&D readers will throw their hands in the air having known this for some time.
Class D is redefining the trade-offs in audio power amplifier design, simultaneously delivering smaller size and higher power density with better sound than Class AB audio systems. Class D also has the advantage of offering low distortion and more stable dynamic response....
In this episode of the Engineering Update, brought to you by Mouser Electronics: The world's fastest sports car: Hennessey Venom GT might have just become the fastest 2-seats sports car in the world. In a run that took place on February 14 at the Kennedy space center, the Venom hit speeds of 270.49 mpg.
Facebook’s recent acquisition of WhatsApp has the technology world abuzz about messaging apps. This begs some questions: What are some other messaging apps? What makes them special? And, with standard texting and calling already built into most cell phones, what exactly can fancy messaging apps do for you?
We know that wearables will transform our lives, but how? Giving tech access to workers who can't use handheld devices, living healthier lives, boosting retail shopping and sales, protecting employees, enabling cheating on tests, and revolutionizing both solving and committing crime.
Factories can transmit industrial temperatures with the Novato (MAXREFDES16#) reference design, a 4–20mA loop-powered temperature transmitter with the HART communication protocol from Maxim Integrated Products, Inc. (San Jose, CA). This smart transmitter enables low-power temperature measurement from -200°C to +850°C with accuracy better than ±0.1% or ±1.0°C.
To meet a specific need, system creators often assemble test solutions that incorporate a variety of hardware and software elements. One key benefit of accepted industry standards is the ability to pick and choose among elements offered by multiple vendors. Achieving success with—and confidence in—the integration of a multi-vendor solution depends on compatibility at the mechanical, electrical and software levels.
Clean hydrogen power that's expected to lower emissions and reduce energy consumption will be coming to the Port of Honolulu in 2015 after the completion of a new fuel cell technology demonstration, one that could lead to a commercial technology for ports worldwide.
Using the Santa Cruz ambient light sensor (ALS) from Maxim Integrated Products (San Jose, CA), factories can quickly configure and monitor multiple red, green, blue (RGB) and infrared (IR) ambient light sensors with the high accuracy required in industrial applications.
Soraa (Fremont, CA) announced today the world’s most efficient LED, which it will integrate into the market’s first full-visible-spectrum, large-form-factor lamps. Soraa’s third generation (Gen3) GaN on GaN LED achieves world-record setting wall-plug-efficiency, outperforming the nearest competitor by 20% at normal operating conditions.
Consumers who fell in love with Amazon's 30-minute drone delivery service but can't wait for the mountain of red tape and regulations standing in the way of "Amazon Prime Air" now have an alternative — move to the United Arab Emirates!
Selecting a Chevy Volt, Tesla Model S, Nissan Leaf — or one of many other new models — shoppers in the United States bought more than 96,000 plug-in electric cars in 2013. That's a tiny slice of the auto market, but it's up eighty-four percent from the year before.
Saelig Company, Inc. (Fairport, NY) has announced the IST8301C, a single-chip 3-axis digital magnetometer sensor, housed in a form factor of 2.5 x 2.5 x 1.0mm, a 12-pin BGA package. The IST8301C is an integrated chip containing 3-axis magnetic sensors with an ASIC controller.
POSITAL-FRABA’s (Hamilton, NJ) IXARC encoders combine the accuracy and dynamic response of optical encoders with the ruggedness and compact form factor of magnetic encoders. Building on the company’s
Drawing a link between reduced fuel consumption and climate change, President Barack Obama said Tuesday that his administration will issue tougher fuel-efficiency standards for delivery trucks by March 2016. Obama said helping these vehicles use less fuel would have the triple benefit of making the U.S. less dependent on imported oil....
Microchip Technology (Chandler, AZ) announced its next-generation family of energy-measurement Analog Front Ends (AFEs) with industry-leading accuracy. The MCP3913 and MCP3914 integrate six and eight 24-bit, delta-sigma Analog-to-Digital Converters (ADCs), respectively, with 94.5 dB SINAD....
Waited till the last second to make your Valentine’s Day plans? Forgot about the day of love entirely? Or maybe you’re snowed in and have to rethink your plans? Not to worry — these five apps, free or inexpensive for multiple operating systems, are ready to save the day. No matter what kind of day you want.
Hey, even journalists have a sense of humor! Enjoy these bumbles, stumbles, outtakes, and bloopers from the latest edition of the Engineering Update. Special thanks to Managing Editor Kasey Panetta and Technical Editor Jason Lomberg for being such good sports!
The Taranis, an unmanned combat demonstrator aircraft being billed as the most advanced aircraft ever built by British engineers took it's first 15-minute test flight under the command of test pilot Bob Fraser, a few months ago at a super top secret location.
Pretty much everyone in our industry is familiar with the long evolution of microcontrollers. So familiar that it’s easy to miss changes in our industry and society, both positive and negative, that accompanied that evolution just as we tend not to see daily changes in our own aging faces.
