Micro and nanoplastics in human blood detected again
Micro and nanoplastics in human blood detected again
A second study by analytical chemists and immunologists of Vrije Universiteit Amsterdam and Amsterdam University Medical Center (VUmc) on the presence of micro and nanoplastics in human blood confirms the team's previous findings (Leslie et al. The first study received overwhelming attention, including a lot of resistance and disbelief especially from the polymer industry.

Scientists solve century-old chemistry riddle
When two solutions of oppositely charged polymers (polyelectrolytes) are mixed, phase separation occurs leading to the formation of a polymer-rich phase and a supernatant phase. The precise distribution of all components, that is polyelectrolytes and counterions, had not yet been determined. Researchers at the University of Twente can now measure quantitatively exactly where these components are distributed using Nuclear Magnetic Resonance (NMR) spectroscopy.

World record reduction in photon emission
Recently, a team of chemists, mathematicians, physicists and nano-engineers at the University of Twente in the Netherlands developed the ultimate device to control the emission of photons with unprecedented precision. This technology could lead to more efficient miniature light sources, sensitive sensors, and stable quantum bits for quantum computing.

Nanobubble research to improve green hydrogen production
Nanobubble research to improve green hydrogen production
In a novel study , researchers of the University of Twente have made significant strides in understanding the behaviour of microand nanobubbles on electrodes during water electrolysis. This process is crucial for (green) hydrogen production. These tiny bubbles form on the electrodes, blocking the flow of electricity and reducing the efficiency of the reaction.

Disorder improves battery life
What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team led by TU Delft has discovered that local disorder in the oxide cathode material increases the number of times Li-ion batteries can be charged and discharged. Their results have been published in Nature .

Magnetism boosts hydrogen production in model catalysts
Researchers at the University of Twente have shown how to improve the efficiency of hydrogen production in an experimental setup. They showed that the magnetic order of the molecules plays a critical role. In the search for green hydrogen, the design of efficient catalyst materials that increase the efficiency and speed of the chemical reaction that produces (green) hydrogen is essential.

The energy transition under the nanoscope: Gravitation funding for ANION
Bringing together chemists and physicists to thoroughly investigate how electrochemical processes work on the smallest scale. That is the goal of the new Advanced Nano-electrochemistry Institute of the Netherlands, or ANION for short. The consortium receives a Gravitation funding of 23.6 million euros for this purpose.

Chemists break barriers and open up super-resolution molecule mass analysis
Chemists break barriers and open up super-resolution molecule mass analysis
Research team measures individual giant molecules with record-breaking precision By modifying and boosting lab equipment, a team of chemists are able to measure individual molecules with unprecedented precision. This precision relates to being able to tell that one single sugar grain is missing from a full 1 kilogram bag of sugar.

Synthetic material sheds new light on how liquids separate
Synthetic material sheds new light on how liquids separate
Hailin Fu found the chemical system that behaves like cell organelles with well-defined segregated areas in a water-based solution by accident. She followed the science to the end though, and she describes her and her colleagues' journey of discovery in a new paper just published in Nature. It is quite rare to see a Nature article, with all'authors on the paper coming from the same institute.

Delft researchers take next step towards better batteries with widely available materials
Delft researchers are developing batteries that can charge faster, offer more stable storage and are made of sustainable materials that are widely available. In doing so, they offer a cheaper alternative to lithium-ion batteries that consist of rare materials and have a high CO2-footprint. A paper was recently published in Nature Energy by Marnix Wagemaker and Alexandros Vasileiadis in collaboration with researchers from the Chinese Academy of Sciences, on fast-charging Na-ion batteries and improvements made to the negative electrode.

Grant of ¤700,000 to gain better understanding of nitrogen dioxide with GELSONDE
Nitrogen dioxide is a gas that has a high proportion of nitrogen precipitation and is hard to measure. But that could soon change: the Dutch Research Council (NWO) Open Technology Programme (OTP) has awarded ¤700,000 to the GELSONDE project, led by Paul Kouwer, from the Radboud University Institute for Molecules and Materials.

This is how Professor René Janssen paves the way to better solar cells
This is how Professor René Janssen paves the way to better solar cells
A professor at TU/e and colleagues have found a way to improve perovskite solar cells. An electric car, heat pump, or robotic lawn mower: the world is electrifying, and so more and more roofs are full of solar panels. The Netherlands is even among the European leaders when it comes to generating solar energy.
