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 ...

Streamline weight controller mounting
When using the HI 4050-PM weight controller from Hardy Instruments, an Encompass Product Partner in the Rockwell Automation PartnerNetwork, you have the option to mount the electronics housing to the rear of its keyboard display or remotely up to 100 feet away. Standard mounting involves attaching the weight controller electronics directly to the rear of its keyboard/display and installing it ...

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 ...

Ensuring lithium ion battery safety in the Black Friday electrical goods scramble
Black Friday is a huge date in retailers’ calendars. According to the NRF, the Black Friday weekend in the US runs from Thanksgiving to Cyber Monday and in 2018, Thanksgiving Day alone generated $3.7bn in online sales. And bargains in electrical and hi-tech goods are high on consumers’ shopping lists around the globe. Just over 50% of consumers[1] are seeking to purchase electrical ...

Long optical paths of large aperture
THE measurement of the vapor phase spectra of compounds having high boiling points presents an experimental problem that may be solved either by heating the absorption cells or by making them very long. In the infra-red region radiation from the hot gases in heated cells decreases the accuracy of absorption measurements. If only a small amount of sample is available, the only possibility is to ...

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 ...

Solar Energy Sector Poised to be Upgraded With Tin-Based Cells
Tinplate has recently gained a lot of attention when it was discovered that it had amazingly high propensity of absorbing the sun rays almost like other known materials productivity. Tinplate is a metal that is silvery-white in appearance and is atomic number 50 in the periodic table. Researchers from North western University have recently proved that tinplate is the same metal as tin creating a ...

Major EV Battery Safety Recalls? Electra`s AI Technology Can Help
Electric vehicle recalls have accelerated as the risk of battery thermal runaway due to faults and failures remains a major pain point in the eMobility industry. General Motors recently took a $1.8 billion hit for battery warranty and replacement costs for the Chevrolet Bolt, according to CNBC, and it is not the only major OEM challenged by battery malfunction. While thermal runaway in electric ...

Combined cycles for CO2-capture with high efficiency
The presented paper gives an overview on combined cycles for CO2-capture with high efficiency focussed on processes using a Solid Oxide Fuel Cell (SOFC), because of the air separating ability of the SOFC-membrane. The SOFC-membrane is only permeable for oxygen ions, so the cathode exhaust gas is oxygen depleted air, which should be discharged to the atmosphere after recycling or using the heat ...

Active prevention of fires caused by damaged batteries during alternative fuel production thanks to Lindner`s Fire Prevention System (FPS)
DI (FH) Thomas Huber & DI Stefan Scheiflinger-Ehrenwerth, MSc. Lindner-Recyclingtech GmbH, Product Management, Spittal an der Drau, Austria Ing. Andreas Säumel Mayer Recycling GmbH, Executive Management, St. Michael, Austria SUMMARY: One of the most pressing recent issues in the mechanical processing and conversion of waste into solid recovered fuels (SRF) is the high fire risk. ...
