On March 31th, Dr. Thu-Ha Nguyen successfully defended her thesis on wave-overtopping processes for very mild sloping and shallow foreshores, supervised by Marcel Stive and Bas Hofland. For Marcel, this was a special occasion, as Thu-Ha was his last PhD in his role of promotor here at TU Delft. Starting back in 2003 with a tall Dutchman who obtained his degree with a thesis on Argus video imaging, Marcel has acted as the promotor of no fewer than 51 PhD candidates, 46 at TU Delft and 5 at other academic institutes.

At the end of this month, two years have passed since I started working at the African Water Corridor Initiative. It will be also 18 months since I have left behind my life in the Netherlands to start my new life in West Africa, in Ghana. My name is Jasper Schakel and in contrast like many other people working at the TU Delft, my employer is not the TU Delft, but the international engineering firm Witteveen+Bos. Two years ago I talked with Doris van Halem where she introduced me to the African Water Corridor

Een belangrijke mijlpaal in de voorbereiding van de kandidaat voor ESA's tiende Earth Explorer-satellietmissie, Harmony, is bereikt dankzij twee vliegtuigen die in strakke formatie boven de Nederlandse Waddeneilanden vliegen en belangrijke gegevens verzamelen over de toestand van de zee en de stromingen. Het hoofddoel van dit uitdagende experiment is om de geometrie na te bootsen waarin de Harmony-satellieten verschillende aspecten van de dynamiek in de oceaan zullen meten om te begrijpen hoe de lucht en het oceaanoppervlak op elkaar inwerken, wat op zijn beurt kan leiden tot verbetering van de weersvoorspelling en de klimaatmodellen.

After almost four years of lab research, the AdOx process will be tested on pilot plant scale. AdOx is an innovative technology for removal of organic micropollutants (OMPs), such as pharmaceuticals, from domestic wastewater effluent. It combines adsorption with oxidation: zeolite granules remove OMPs from treated wastewater effluent by adsorption in a fixed bed filter, and the zeolite filter is regenerated with ozone gas after the zeolite granules are exhausted. The process is very selective for OMPs, cost-effective and extremely sustainable: the CO2-footprint is low, no bromate and oxidation by-products are released to the receiving surface water, and the ozone use is low. It is a very competitive technology compared to GAC filtration and direct ozonation of wastewater effluent.

Lithium is a scarce resource that is essential for the production of batteries. Yet batteries we urgently need to enable the energy transition, as they provide efficient ways to store wind and solar energy. We therefore need ways to process lithium more efficiently, techniques to refine and ways to recycle. A consortium of European companies and universities, including TU Delft’s Resources & Recycling group, aims to set up the first-ever Lithium supply chain in Europe.

Elke mening telt! Maar hoe houdt een bedrijf als de NS rekening met alle verschillende meningen van treinreizigers om een perfecte match te creëren tussen fiets en OV? Simone Hoskam, masterstudent Civil Engineering, zag hierin een uitdaging om echt een bijdrage te leveren aan de transportwereld. Met haar onderzoek kon zij een duidelijk advies uitbrengen aan de NS om de combinatie tussen fiets en OV in de toekomst nog beter te maken.

Virtual Reality (VR) provides possibilities to obtain complete experimental control and automatically collect behavioral data of vulnerable road users when interacting with automated vehicles. The usage of VR has attracted strong attention to play a key role in studying and better understanding interactions between autonomous vehicles and vulnerable road users.
