Overcoming Mass Transport Limitations in Electrochemical Reactors with a Pulsating Flow Electrolyzer

Electrochemical processes are a promising technology for industrial production of chemicals. One of the major drawbacks of electrochemical systems is the low mass transfer of reactants toward the active surface area of the electrode. In this paper, an approach is presented to enhance the mass transfer and increase the overall performance of the...

A Ka-Band Spaceborne Synthetic Aperture Radar Instrument: A modular sparse array antenna design

The article presents the design of a Ka-band synthetic aperture radar (SAR) instrument based on innovative phased-array antennas, with steering capability in azimuth and elevation. To limit the complexity and costs associated with conventional large active arrays with regular layouts, a sparse array concept is presented. The proposed approach...

Product services for a resource-efficient and circular economy - A review

Since the 1990s, Product Service Systems (PSS) have been heralded as one of the most effective instruments for moving society towards a resource-efficient, circular economy and creating a much-needed 'resource revolution'. This paper reviews the literature on PSS in the last decade and compares the findings with those from an earlier review in...

Large area inkjet printing for organic photovoltaics and organic light emitting diodes using non-halogenated ink formulations

The transfer of laboratory scale solution processing of organic electronics to large area roll-to-roll production requires the use of up-scalable deposition techniques. Furthermore, industrial production demands the omission of halogenated and other harmful solvents. Here, the authors discuss large area inkjet printing using industrial...

Large area inkjet printing for organic solar cells and OLEDs using non-halogenated ink formulations

Transferring lab-scale processes of organic electronics to large area roll-to-roll production requires the use of up-scalable deposition techniques. Furthermore, industrial production demands the omission of halogenated and other harmful solvents. Here we discuss the solution processing of organic light emitting diodes (OLEDs) or organic...

Towards high speed inkjet printed electronics - Technology transfer from S2S to R2R production

An economically successful implementation of printed electronics technologies in industrial production processes requires high throughput and large scale compatible manufacturing techniques. Roll-to-roll inkjet printing and photonic sintering of metal-based conductive inks on flexible plastic substrates is a promising approach in this respect....

Properties and applications of starch-converting enzymes of the alpha-amylase family

Starch is a major storage product of many economically important crops such as wheat, rice, maize, tapioca, and potato. A large-scale starch processing industry has emerged in the last century. In the past decades, we have seen a shift from the acid hydrolysis of starch to the use of starch-converting enzymes in the production of maltodextrin,...
