Making photochemistry scalable – an operationally simple falling film looping photoreactor

A Scalable and Operationally Simple Radical Trifluoromethylation

The large number of reagents that have been developed for the synthesis of trifluoromethylated compounds is a testament to the importance of the CF3 group as well as the associated synthetic challenge. Current state-of-the-art reagents for appending the CF3 functionality directly are highly effective; however, their use on preparative scale has minimal precedent because they require multistep s...

Techniques for Making IP Multicast Simple and Scalable

This paper describes Root Administered Multicast Addressing (RAMA), a protocol for wide-area IP multicast that scales to a large number of simultaneous groups with topologically distant members. RAMA solves the widearea “rendezvous” problem by making the root of the distribution tree explicit in the multicast group identifier. This is done by extending the 4-byte IPv4 multicast group address fo...

Wave Evolution on a Falling Film

Since the pioneering experiment by the father-son team of the Kapitza family during their house arrest in the late forties (Kapitza & Kapitza 1949), wave evolution on a falling film has intrigued many researchers. One of its main attractions is its simplicity-it is an open-flow hydrodynamic instability that occurs at very low flow rates. It can hence be studied with the simplest experimental ap...

Improving Heat Transfer in Falling Film Evaporators in Food Industries

Falling film evaporators, due to their high heat transfer coefficients, low energy loss, rather a low holdup time, and the ability to handle high capacities have broad applications in food industries. Thus, this kind of evaporator is being used in the production of temperature sensitive compounds such as syrups. In this study, through modelling of the falling film evaporator with the use of...
