New Approach to Ultrafast Light Pulses Discovered
2D materials called molecular aggregates are effective light emitters; however, their potential as components for new kinds of optoelectronic devices has been limited by their relatively slow response time. Researchers at MIT, the University of California, Berkely and Northeastern University have found a way to overcome this problem.
Burning Used Toilet Paper to Create Electricity
Currently, impossible amounts of used toilet paper collect in municipal sewage filters and eventually go through a composting process.
First Production of Hydrogen from Tidal Power
The European Marine Energy Centre has produced the world’s first tidal-powered hydrogen, using an electrolyzer at its test facility in Orkney, Scotland.
PEM Fuel Cell Design Eschews Platinum
A non-precious-metal catalyst reduces the amount of platinum used by 80 percent.
The Bigger Energy Consumer: EV Charging vs Home Heating
Charging an electric vehicle (EV) consumes less energy than several common household appliances.
Refinery Planned to Showcase Clean Carbon Fuel
The facility will process waste coal and yield a high-quality, clean carbon fuel.
Video Learning Opportunity: Automated Testing of Semiconductor Dies Before Packaging
Dies are often tested for functionality before they are packaged to save money and time, eliminating the packaging of a faulty die into a chip. To test a die you need a machine that can make many contacts with the points on the die called micro bumps.
Nanogenerator Harvests Power in Blood Vessels
The fiber-shaped fluidic nanogenerator converts the energy of any flowing liquid, including blood in blood vessels, into electricity.
Microturbine-powered Hybrid Electric Truck Tested
The microturbine operates on compressed natural gas and functions as a range extender to charge a 47-kilowatt-hour lithium-ion battery pack.
A Scheme for Sharing Renewable Energy
A team of engineers has developed an algorithm that would enable homes to utilize and share renewable energy sources during power outages.
Battery-free Bike Lights
Reelight, a Danish manufacturer, has designed bicycle lights that activate as soon as the rider begins to pedal.
Electric Motor for Hybrid City Bus Use
The 650-volt electric motor drives the vehicle at low speeds when enough energy is available.
The E-Axle Powertrain for Electric Vehicles
A new generation electric axle drive, or e-axle, combines three powertrain components into one unit.
Nordex Enters the 4 MW Wind Class
The N149/4.0-4.5 turbine is designed specifically for light-wind regions.
Honeycomb of Solar Cells Saves Space and Works in Harsh Conditions
A new generation of advanced photovoltaics could be the result of packing tiny solar cells together, like the microlenses in the compound eye of an insect, according to a group of Stanford University scientists.
Progress Posted in European SOFC Project
Single cell, coatings, sealing and stack design technologies developed in Europe were tapped to produce a high-performance 1 kW SOFC stack.
Dermatologist Designing Wristband To Alert Wearer to Potential for Sunburn
Called the Eclipse RX, Matthys believes that the band will encourage users to take part in outdoor activities while simultaneously taking care of their skin.
Further Along the Path to Hydrogen Fuel Cells
New research shows promise for using liquid-metal membranes to generate the pure hydrogen needed to power hydrogen fuel cell vehicles.
U.S., Swiss Researchers Break 35 Percent PV Cell Efficiency
The record efficiency was achieved for multi-junction solar cells.
A New Twist on Energy Harvesting
A carbon nanotube yarn generates electricity and harvests waste thermal energy from the environment when twisted or stretched.
