Nature-inspired self-sensing materials could lead to engineering breakthoughs
Nature-inspired self-sensing materials could lead to engineering breakthoughs
The cellular forms of natural materials are the inspiration behind a new lightweight, 3D printed smart architected material developed by an international team of engineers. The team, led by engineers from the University of Glasgow, mixed a common form of industrial plastic with carbon nanotubes to create a material which is tougher, stronger and smarter than comparable conventional materials.

Greener route to widely used industrial material
Scientists from Cardiff University have taken a step towards a greener, more sustainable way of creating a plastic material found in a range of items from toothbrushes and guitar strings to medical implants, construction materials and car parts. In a new paper published today , the team report a brand-new method of creating cyclohexanone oxime - a pre-cursor to the plastic material Nylon-6 which is a key construction material used in the automotive, aircraft, electronic, clothing and medical industries.

Imaging chemical kinetics at liquid-liquid interfaces
Imaging chemical kinetics at liquid-liquid interfaces
Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of dynamics on the sub-millisecond timescale, which is very difficult to do with current applications.

Urine treatment: from trial and error to exciting innovation
Urine treatment: from trial and error to exciting innovation
What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine.

New insights into gene expression in nerve cells
New insights into gene expression in nerve cells
Genes are the carriers of our genetic information. They are read in our cells and used to produce ribonucleic acids (RNAs). During this process, termed transcription, the enzyme RNA polymerase II has a decisive influence on the exact time at which genes are read and on the intensity with which this happens.

Researchers Transform an Amorphous Solid Into a New Lithium-Ion Battery Material
Researchers at the University of California San Diego and Boise State University have developed a new approach to making novel lithium-ion battery materials. The approach transforms a non-crystalline material into a crystalline one—by cycling it with lithium. Using this approach, the team transformed a non-crystalline (amorphous) material called niobium oxide into a novel crystalline Nb2O5 anode with exceptional lithium storage and fast cycling.

Natural gas could bridge gap from gasoline to electric vehicles, thanks to metal-organic frameworks
As the world turns its attention to electric vehicles as a replacement for gas-powered cars and trucks, some vehicles such as long-haul trucks and planes will need a bridge between gas and electric. Natural gas could be a viable alternative. It's widely available and burns more cleanly than gasoline.

Love is in the air
Love is in the air
More blood flow to the genitals, an increased pulse and dilated pupils: These physical characteristics reveal that a person is sexually aroused. But lust can also be detected in the breath, as a study of an international research team has now shown. According to the study, a characteristic signature of volatile molecules is found in the breath of sexually aroused people.

New mechanism to transfer chirality between molecules in the nanoscale field
New mechanism to transfer chirality between molecules in the nanoscale field
If we compare the right to the left hand, we can see these are specular images —that is, like symmetrical shapes reflected in a mirror— and they cannot superimpose on each other. This property is chirality, a feature of the matter that plays with the symmetry of biological structures at different scales, from the DNA molecule to the tissues of the heart muscle.

How equal charges in enzymes control biochemical reactions
How equal charges in enzymes control biochemical reactions
Research team led by Göttingen University describes fundamental principle of enzyme catalysis It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes - the biological catalysts in all living organisms - form or break chemical bonds.

Atomic terahertz vibrations generate soliton molecules
Atomic terahertz vibrations generate soliton molecules
Stable packets of light waves - called optical solitons - are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers at the Universities of Bayreuth and Wroclaw have now solved the puzzle of how these temporal links are formed.

Revolutionary images of the birth of crystals
Revolutionary images of the birth of crystals
A team from the UNIGE has succeeded in visualizing crystal nucleation - the stage that precedes crystallization - that was invisible until now. At the interface between chemistry and physics, the process of crystallization is omnipresent in nature and industry. It is the basis for the formation of snowflakes but also of certain active ingredients used in pharmacology.

Golden wedding for molecules
Golden wedding for molecules
Chemical syntheses in liquids and gases take place in three-dimensional space. Random collisions between molecules have to result in something new in an extremely short time. But there is another way: on a gold surface under ultrahigh vacuum conditions, molecules lying still next to each other can be made to combine - even those that would never want to react with each other in a liquid.

New way to predict pollution from cooking emissions
New way to predict pollution from cooking emissions
Organic aerosols from cooking may stay in the atmosphere for several days because of nanostructures formed by fatty acids as they are released into the air. Organic aerosols - such as those released in cooking - may stay in the atmosphere for several days because of nanostructures formed by fatty acids as they are released into the air, new research finds.

More developed countries dumping toxic e-waste in Global South, University of Toronto researchers find
People in mainland China and the Global South suffer the brunt of emissions of toxic chemicals from consumer goods used in more-developed countries, according to a new study. Researchers, including Frank Wania and Kate Tong of the University of Toronto Scarborough, say "core regions" in Europe, North America and parts of Asia have offloaded  polybrominated diphenyl ethers (PBDEs) emissions to less developed parts of the world.

How to find anti-cancer agents
How to find anti-cancer agents
Researchers at the Paul Scherrer Institute PSI and the Italian Institute of Technology IIT have developed a novel substance that disables a protein in the cell skeleton, leading to cell death. In this way, substances of this type can prevent, for example, the growth of tumours. To accomplish this, the researchers combined a structural biological method with the computational design of active agents.

How to design safe and sustainable chemicals
How to design safe and sustainable chemicals
With many human-made chemicals, problems regarding public health and the environment become apparent only years after their widespread use. A team of researchers from the University of Amsterdam and Utrecht University now propose a way to change that. In an article in the journal 'Chemosphere' they present a method for (re)designing safe and sustainable chemicals.
