Going for the (Recycled) Olympic Gold in Tokyo
Organizers of the 2020 Tokyo Olympic and Paralympic Games have decided to use e-waste to manufacture the 5,000 medals that athletes will be awarded.
Paper Beats Felt as Microbial Fuel Cell Electrode
A durable, low-cost bioelectrode material for microbial fuel cells was demonstrated by University of Rochester, NY, researchers.
Pulse of Engineering: Where Are the New Engineers?
Our annual survey suggests that firms are losing specialized knowledge faster than they can replace it and fewer new hires are coming on board.
Frameless PV Modules Undergo Testing
In the assembly approach, solar cells are fixed in a gas-filled space between two glass panes with adhesive pins, eliminating the need for encapsulants and backsheets as well as aluminum frame and sealing.
Leaching Metals from Used Batteries
A hydrometallurgical technique for efficiently reclaiming lithium and cobalt from used lithium-ion batteries was demonstrated by researchers from International Islamic University Malaysia.
Economics Favor Larger Tidal Energy Deployment, Study Says
Deep Green technology has been likened to an underwater kite which produces electricity when the water current creates a hydrodynamic lift force on the wing, pushing its mounted turbine through the water.
Art from Auto Tailpipe Emissions
KAALINK is a mechatronic system which consists of electrostatic and other filtration equipment, sensors, and a capture unit. The device captures 95% of particular matter pollution without inducing back-pressure.
Valve Designed to Increase Oil Recovery
An autonomous inflow control valve shuts off the gas and/or water in oil wells, leading to increased oil recovery rates.
How Engineers Can Adapt Infrastructure Design for a Changing Climate
A primary challenge to the engineering community is developing strategies for the uncertainty that comes with projecting future climate conditions.
Nanotech Nurtures Slow-Release Fertilizer
The high solubility of urea fertilizer, which leads to waterway eutrophication and nitrogen dioxide emissions problems in developing areas, is addressed at the nanoscale.
New Gas Turbines for Oil and Gas Service
GE Oil & Gas has expanded its gas turbine portfolio with the addition of an aeroderivative gas engine and a heavy-duty gas turbine for the oil and gas sector.
Repairing Potholes for the Long-Term
A pothole repair technology based on infrared heating could save local UK authorities £3.5bn in 2019 by making repairs cheaper and longer-lasting.
