KU Leuven scientists crack the code for affordable, eco-friendly hydrogen gas
KU Leuven scientists crack the code for affordable, eco-friendly hydrogen gas
Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. After ten years of development, the panel can now produce 250 litres per day - a world record, according to the researchers. Twenty of these solar panels could provide electricity and heat for one family for an entire year.

KU Leuven researchers use sound waves to prevent small chemical reactors from clogging up 
Companies are keen to use miniature chemical reactors to make pharmaceuticals and fine chemicals, but are discouraged by their tendency to clog up. Researchers at KU Leuven have now devised an elegant way of using sound waves to keep the chemicals flowing. The chemical industry conventionally produces in large batches, but this approach has drawbacks.

A USB stick? In the distant future, a little powder should suffice
( 29-10-2018 ) Whether you think about bank accounts, YouTube videos or QR codes, everything is saved as zeros and ones, or data, on a computer. The storage equipment available might not be capable of holding all that information much longer. Ghent University successfully investigates alternative data storage methods There are two major issues.

Why silver clusters emit light
Clusters of silver atoms captured in zeolites, a porous material with small channels and voids, have remarkable light emitting properties. For instance, they can be used for more efficient lighting applications as a substitute for LED and TL lamps. Until recently, scientists did not know exactly how and why these small particles emit light.

Graphene smart membranes can control water
Graphene smart membranes can control water
Researchers have achieved a long-sought-after objective of electrically controlling water flow through membranes, as reported in Nature. This is the latest exciting membranes development benfitting from the unique properties of graphene. The new research opens up an avenue for developing smart membrane technologies and could revolutionise the field of artificial biological systems, tissue engineering and filtration.

New material reveals hidden message when you breathe on it
New material reveals hidden message when you breathe on it
Chemists from Belgium and China have produced a new material that changes colour under a flow of human breath. After a while, the colour returns to normal. This creates possibilities for encryption and anti-counterfeiting. Our clothes, food and everyday devices get their colour from dye or pigments that absorb light.

Researchers examine ’Sunflowers’ by Van Gogh
Introduction: Vincent Van Gogh used only two yellows to paint Sunflowers: a light-fast and a light-sensitive type. Researchers from the Universities of Antwerp, Perugia and Delft together with museum staff have painstakingly examined Sunflowers by Vincent van Gogh (Van Gogh Museum, Amsterdam). He painted this iconic work, a composition dominated by yellow tints with some orange and blue accents, in 1889 in Arles, France.

Scientists develop herb passports for beer brewery
The traditional pint is increasingly losing ground to speciality beers. Using herbs is one of the ways to give these beers their specific flavour. Research shows that the taste of these herbs depends a great deal on where they are grown and on their harvest year. Brewers can use this knowledge to maintain the flavour and quality of their product.

Fish consumption and exposure to methylmercury
Fish consumption and exposure to methylmercury
A study conducted by a team of international researchers, including Krishna Das from the Laboratory of Biological Oceanology ( FOCUS Research Unit), presents new data on the level of mercury in seven distinct populations of European seabass ( Dicentrarchus labrax ), an edible species whose flesh is highly appreciated by gourmets.

Oligorotaxanes, artificial molecular machines capable of exceeding the performance of natural proteins
Researchers at the NANOCHEM laboratory (MolSys Research Unit) of the University of Liege have studied molecules synthesized by Sir Fraser Stoddart's group, Nobel Prize winner in Chemistry 2016 and professor at Northwestern University. The results obtained during this research and published in Nature Nanotechnology (1) open up new paths in the use of molecular machines, these synthetic molecules that carry out controlled motion on demand.

NO sex without KISS(peptin)!
NO sex without KISS(peptin)!
A research team led by Prof. Julie Bakker (GIGA-ULiège) and Prof. Ulrich Boehm (Saarland University, Germany) has made a major advancement in our understanding of how the brain controls sex. Using female mice as a model, the researchers found that a hormone in the brain, (appropriately) called kisspeptin, drives both attraction to the opposite sex and sexual behavior.

Lighting the way to switch chemical reaction pathways
Could the manufacture of the integrated circuits and chips for our everyday electronic devices be made simpler, safer and cheaper simply by being able to switch coloured light on and off? Researchers from Queensland University of Technology (QUT, Australia), Germany's Karlsruhe Institute of Technology (KIT) and Belgium's Ghent University have stepped towards this  by pioneering a system that modulates visible, coloured light to change the reactions of a powerful chemical coupling agent.

UCL tests new molecule to prevent cancer metastasis in mice
UCL tests new molecule to prevent cancer metastasis in mice
Three years ago, Pierre Sonveaux, a researcher at the UCL Institute of Experimental and Clinical Research, and his team discovered that when the mitochondria (the power plants) of tumour cells are impaired, they promote the formation of metastases. Subsequently, the researchers verified a molecule, MitoQ, as capable of preventing these impairments and thus tumour metastases.

Separating methane and COâ‚‚ will become more efficient
To make natural gas and biogas suitable for use, the methane has to be separated from the CO2. This involves the use of membranes: filters that stop the methane and let the CO2 pass through. Researchers at KU Leuven have developed a new membrane that makes the separation process much more effective.
