Superconducting quantum microwave circuits can function as qubits, the building blocks of a future quantum computer. A critical component of these circuits, the Josephson junction, is typically made using aluminum oxide. Researchers in the Quantum Nanoscience department at the Delft University of Technology have now successfully incorporated a graphene Josephson junction into a superconducting microwave…
Nanotransistor Makes it Easy to Measure Electrolyte Concentration in Blood
Testing the blood of patients that doctors believe may be suffering from an electrolyte imbalance is usually a major effort because various selective tests have to be performed. Electrolytes are certain nutrients or chemicals in the body that carry out a number of important functions, such as regulating the heartbeat. A disruption of the electrolyte…
New Hybrid Biomaterial Makes Hip Implants Last Longer
It is not something you will find in nature, but it can be created using a 3D printer and existing biomaterials: a hybrid meta-biomaterial that promotes bone growth. TU Delft researchers have developed a meta-implant that combines a conventional meta-biomaterial with an auxetic meta-biomaterial. This is important since — unlike natural materials — auxetics have…
Origami Inspires 3D Printing Alternative
Inspired by the Japanese art of paper folding (origami), researchers at TU Delft are developing an alternative to 3D printing that allows the final products to have many more functionalities than what is possible with 3D printing. Those additional functionalities could, for instance, be used in medical implants or devices incorporating flexible electronics. In their…
