Optimization of copper removal from aqueous solutions in a continuous electrochemical cell divided by cellulosic separator
Copper, as an inseparable part of many industrial discharges, threatens both public and environmental health. In this work, an electrochemical cell utilizing a cellulosic separator was used to evaluate Cu removal using graphite anodes and stainless steel cathodes in a continuous-flow mode reactor. In the experimental matrix, Cu concentration (1–5 mg L−1), electrolysis time (20–90 min), and ...

Demonstration of a 33% efficient Cassegrainian Solar Module
Abstract The Cassegrainian solar concentrator module concept we shall describe here uses a primary and a dichroic secondary mirror to split the solar spectrum into two parts and direct the infrared and near visible portions of the spectrum to two separate cell locations. An efficiency of 32.9% (STC) is reported measured outdoors for a solar concentrator PV module using InGaP/GaAs dual junction ...

Using the EA8000 X-Ray analyser to improve lithium ion battery performance and reliability
The EA8000 X-Ray Particle Contaminant Analyser is designed to help lithium ion battery (LiB) manufacturers improve the safety, performance and yield of their product. The analyser is engineered to rapidly detect and analyse unwanted metal particles within the battery. These particles are known to cause sudden catastrophic failure of the batteries, often accompanied by fire or explosion. The ...

Reducing fire and explosion risk of lithium-ion batteries
On the 7th January 2013 cleaning staff onboard a Boeing 787 aircraft noticed smoke in the rear cabin. Closer inspection by a mechanic discovered a fire originating from the lid of the APU battery case. Fortunately, the plane was parked at Logan International Airport, USA, at the time, so none of the 183 passengers and 11 crew were hurt. Nine days later, on 16th January 2013, a Boeing 787 had to ...
