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 .

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.

Utrecht chemists discover mechanism to design more sustainable molecular catalysts
Utrecht scientists, under the supervision of Marc-Etienne Moret, have discovered a new mechanism to build molecular catalysts. The new mechanism involves the earth-abundant metal nickel instead of precious metals that are often used as part of molecular catalysts. Moret: "This discovery initiates a new area of research that brings about a whole new concept for the design of more sustainable catalysts." In 2017, chemistry researcher Marc-Etienne Moret received an ERC Starting Grant  to study new catalysts with better properties.

Observations of planetary cradles find water and conditions for forming Earth-like planets even in harsh environments
Planets like our Earth, including planets with water, could form even in the harshest known star-forming environments, drenched by hard UV light from massive stars. That is a main result of analyses of new observations of such an environment with the James Webb Space Telescope (JWST), conducted by, amongst others, Rens Waters and student Lars Cuijpers from Radboud University.

New Biodegradable Polymers Traceable Without Toxic Contrast Agents
Polyphosphoesters, molecules containing phosphorus as central element, are easily traceable without the need for contrast agents, thanks to developments by researchers of the University of Twente. Normally, these molecules display a similar molecular composition of our DNA, leading to considerable 'noise' in the image.

More efficient electrodes for CO2 recycling
More efficient electrodes for CO2 recycling
With the ever-increasing interest in renewable energy, scientists are continuously searching for new technologies to store energy. CO2 electrolysis is a promising way to store energy whilst recycling carbon dioxide. By applying electricity, CO2 and water react and produce more complex molecules. A study published in Nature Communications lead by Hugo van Montfort at TU Delft has presented a new design of electrodes that improves the efficiency of CO2 electrolysis.

How a small 'gap' brings green energy storage through electrolysis closer
How a small ’gap’ brings green energy storage through electrolysis closer
An article by TU/e researcher Thijs de Groot and his team on the usefulness of a small cathode gap in alkaline electrolyzers appeared in the International Journal of Hydrogen Energy recently. Green hydrogen is a serious contender to become a renewable energy carrier. For example, we could use it to store solar and wind energy during peaks in order to utilize the energy when the sun is no longer shining and the wind is calm.

New model to help valorize lignin for bio-based applications
Woody biomass and wheat straw are all sources of the natural polymer lignin with more than 50 megatons of lignin produced annually at commercial scale. However, most is burned to produce energy, which alternatively could be used to make useful chemicals. A major issue with producing chemicals from lignin though is that the properties of lignin vary from source to source and from season to season.

Another strong greenhouse gas is on the rise - and it spells trouble for hydropower
The Earth's warming climate is largely caused by the rise in greenhouse gases carbon dioxide and methane. However, there are additional gases capable of warming the planet. New research from climate scientists at Utrecht University reveals that emissions of the potent greenhouse gas nitrous oxide (N2O) from streams and reservoirs have more than tripled over the last century.

Unraveling the super-complex structure of supercooled liquids
With novel calculations TU/e researchers reveal new properties of supercooled liquids that could be used in efficient optical materials and recyclable plastics. When cooled to their freezing point, most liquids become solids or crystallize. In other words, the molecules arrange themselves in a perfectly ordered fashion, which physicists call a crystal.

Eefjan Breukink appointed professor of Microbial Membranes and Antibiotics
Utrecht University has appointed chemist Eefjan Breukink as professor of Microbial Membranes and Antibiotics. Breukink and his group are engaged in research aimed at finding new antibiotics that target bacterial cell membranes, the structures that separate the inside and outside of bacteria. Breukink: "It is my dream to discover an antibiotic that will truly aid us in combating antibiotic-resistant bacteria." Cell membranes are a fundamental component of all living cells, whether they are bacterial, animal, plant, or fungal.

Cleaner air with a cold catalytic converter
Cleaner air with a cold catalytic converter
New paper in the prestigious journal Science outlines a new catalyst that can purify exhaust gases at room temperature. Although passenger vehicle catalytic converters have been mandatory for over 30 years, there is still plenty of room for improvement. For instance, they only work correctly when the engine is sufficiently hot, which is not always the case, especially with hybrid vehicles.
