Another surprising observation of electric heating of glass is that the hot spot near the positive electrode may meander around as seen in the video frames several seconds apart in the figure here. For the video and explanation of this phenomenon see the publication at: https://doi.org/10.1038/s41598-019-39431-8

Researchers explored a material that has an internal structure, shown in 3D in left panel, that consists of triangles and hexagons arranged in a pattern similar to that of a Japanese kagome basket.
Cosel’s high reliability 40W DC/DC converters MGF40 series for demanding applications
Danish researchers just solved one of the biggest challenges of making effective nano electronics based on graphene: to carve out graphene to nanoscale dimensions without ruining the electrical properties. This allows them to achieve electrical currents orders of magnitude higher than previously achieved for such structures. The work shows that the quantum transport properties needed for future electronics can survive scaling down to 10 nanometer dimensions.
This is a picture of the actual metamaterial consisting of a field of specifically tailored cylinders.
A layer of red phosphorus in rechargeable lithium metal batteries can signal when damaging dendrites threaten to create a short circuit. The technique developed at Rice University could lead to more powerful lithium metal batteries.
Rice University scientists have combined laser-induced graphene with a variety of materials to make robust composites for a variety of applications.
PROMYS project researchers are developing new microsystem concepts for use in medical monitoring.
A block copolymer of PVDF (black) and an insulating polymer chain (blue) form a block copolymer. Through phase separation, the blocks assemble in films. The dielectric properties can be tuned by varying composition and length of the blocks.
