After a gastric reduction, severely overweight patients do not only lose weight fast, gradually they are also affected less by additional disorders such as high blood pressure and cholesterol, diabetes and sleep apnea. Graduating student Ruben Deneer used data from Catharina Hospital to develop the Metabolic Health Index: a measure for the extent to which patients still suffer from these so-called comorbidities.
While you cannot see infrared light, this invisible component of the sunlight can have a great impact on the indoor temperature. For this reason the Indian PhD candidate Hitesh Khandelwal made window panes that allow infrared light to pass through when it is cold, and to reflect it under warm conditions. These ‘smart windows’ can help save heating and air conditioning costs alike.
Hydrogen is a raw material that is used widely in the chemical industry and is also regarded as an important energy carrier for a sustainable future. However, present-day production methods of hydrogen consume a lot of energy, and its transportation is also anything but efficient. For this reason PhD candidate Arash Helmi from Iran has been working on a membrane reactor which makes it possible to produce very pure hydrogen locally on a small scale.
By controlling the rotational speed of each wheel separately, the new electric race car of University Racing Eindhoven (URE) must become faster than its predecessors. Master’s student Automotive Martijn van der Drift graduated on this new control strategy.
In the transport of flowers and other perishable products, speed often has priority over transport costs and the environment. The sophisticated logistical models of the Iranian PhD candidate Maryam SteadieSeifi make an environmentally friendlier solution possible by helping to fit barges and trains in with existing air and road traffic, without affecting the profit.
We operate our smartphones almost exclusively with the touchscreen. Graduate Ruben Daems is trying to change this by means of the Bendle, a prototype of a ‘shape-changing’ smartphone, which you can operate by pressing and bending it.
Nanowires may be highly suitable for converting heat into electricity. When researching that possibility, PhD candidate Milo Swinkels discovered that some nanowires are almost perfect thermal conductors - the exact opposite of what is required for a thermo-electric appliance. Yet not all hope is lost for his young field of specialization.
