Chalmers team develops optical nano-sensor for detecting pollution

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a small, optical nano-sensor for pollution detection which can be mounted onto an ordinary streetlight. The technology is already in use in western Sweden, and researchers and other interested parties hope that the sensor could soon be used in many broad contexts.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

Researchers in Sweden and Spain have devised a three-step process for the conversion of precipitated kraft lignin from black liquor into green diesel. Since black liquor is derived from wood, it is the most important renewable bio-fuel, particularly in Sweden and Finland. Their paper appears in the journal ChemSusChem. Earlier post.)

Chalmers team tests blends of OME3-5, HVO and RME in light- and heavy-duty CI engines

Green Car Congress

A team at Chalmers University (Sweden) has tested blends of OME 3-5 , HVO and RME in a light- and heavy-duty CI engine. Performance and emissions were compared to the reference fuels fossil diesel and HVO in a single-cylinder light duty and heavy duty compression ignition engine at different loads. Preuß et al.

Secrets of a Danish Castle

Baua Electric

Although at night Copenhagen’s lights appeared like illuminated pinpricks across the dark Baltic Sea, Stevns seemed an impossibly remote place, where superstitions were strong and conversations short — “Yes, it’s not that,” spoken very slowly, was a particularly popular beginning, middle and end to many interactions.

How Generative AI Helped Me Imagine a Better Robot

Cars That Think

The phrase refers to how the AI software iterates through design mutations and converges on high-performing designs. We plan to build such a robot in my lab at Uppsala University , in Sweden. Also, they take a fraction of the time to design compared to traditional components. McClelland calls these new designs “evolved structures.”

Metamaterials Could Solve One of 6G’s Big Problems

Cars That Think

At Huawei Sweden , where I work, we’ve had a lot of discussions about the best placement of RIS units in urban environments. The films are fabricated from transparent conductive oxides (such as indium tin oxide ), graphene, or silver nanowires and do not noticeably reduce light transmission.
