A gentler, more precise laser cutting technique

Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials. Now scientists from McGill University have developed a gentler, more precise technique using low-power visible light.

Laser writing may enable 'electronic nose' for multi-gas sensor

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu "Larry" Cheng, assistant professor of engineering ...

Cooking up a conductive alternative to copper with aluminum

In the world of electricity, copper is king—for now. That could change with new research from Pacific Northwest National Laboratory (PNNL) that is serving up a recipe to increase the conductivity of aluminum, making it ...

Exploring nature's own assembly line

Today the raw ingredients for virtually all industrial products, ranging from medicines to car tires, come from non-renewable chemical feedstocks. They are produced in fossil fuel refineries that emit greenhouse gases, such ...

Exotic carbon microcrystals in meteorite dust

Unusually shaped microcrystals formed of pure, graphite-like carbon were discovered in the dust of the 21st-century's largest meteorite. They are likely to have grown in layers from complex carbon nuclei such as fullerene.

Climate protection: CO2 turned into methanol

For reasons of climate protection, carbon dioxide must not be released into the atmosphere. Wherever the formation of carbon dioxide cannot be prevented, it should be captured and converted into other substances.

Reaction insights help make sustainable liquid fuels

Methanol, produced from carbon dioxide in the air, can be used to make carbon neutral fuels. But to do this, the mechanism by which methanol is turned into liquid hydrocarbons must be better understood so that the catalytic ...
