From petroleum to wood in the chemical industry: cost-efficient and more sustainable
From petroleum to wood in the chemical industry: cost-efficient and more sustainable
An interdisciplinary team of bio-engineers and economists from KU Leuven has mapped out how wood could replace petroleum in the chemical industry. They not only looked at the technological requirements, but also whether that scenario would be financially viable. A shift from petroleum to wood would lead to a reduction in CO2 emissions, the researchers state in Science .

Clusters of gold atoms form peculiar pyramidal shape
Clusters of gold atoms form peculiar pyramidal shape
Freestanding clusters of twenty gold atoms take the shape of a pyramid, researchers discovered. This is in contrast with most elements, which organize themselves by forming shells around one central atom. The team of researchers led by KU Leuven published their findings in Science Advances . Clusters composed of a few atoms tend to be spherical.

Atomically thin micas as proton-conducting membranes
Inleiding: Recent work from CMT researchers (Dr Bacaksiz and Prof Peeters) provide theoretical support for experiments done in Manchester which show that micas are excellent proton conducting membranes. (Physworld News) One-atom thick materials like graphene (a 2D sheet of carbon) conduct protons extremely well but they become impermeable to protons the thicker they get.

New insulation technique paves the way for more powerful and smaller chips
Researchers at KU Leuven and imec have successfully developed a new technique to insulate microchips. The technique uses metal-organic frameworks, a new type of materials consisting of structured nanopores. In the long term, this method can be used for the development of even smaller and more powerful chips that consume less energy.

Looking past the hype: KU Leuven researchers shed more light on their hydrogen panel
Looking past the hype: KU Leuven researchers shed more light on their hydrogen panel
How did bioscience engineers at KU Leuven manage to convert water vapour directly into hydrogen gas, with record efficiency? And does their hydrogen panel signal the end of fossil fuels' We asked Johan Martens and Tom Bosserez from the Centre for Surface Chemistry and Catalysis for the answers. Professor Johan Martens and his team have had some pretty hectic weeks.

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.  Under a watery sun, Professor Johan Martens and his research team roll the solar panel onto the lawn in front of the Centre for Surface Chemistry and Catalysis at KU Leuven.

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.

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.

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.
