Researchers at the Fraunhofer Institute for Applied Polymer Research IAP have developed a foil that changes into polyurethane foam (PU foam) when heated—entirely without health risks. The foil allows ...

Water is ubiquitous and seemingly ordinary, possessing no distinct color or odor. Though we often take water for granted, it is by no means a simple substance. As a consequence of its chemical ...

Density also depends on the material. A piece of iron with the same dimensions as a piece of aluminium will be heavier because the atoms are more closely packed. Scientists can measure how tightly ...

At the same time, coating materials are remarkably diverse, encompassing a wide range of chemistries, such as acrylic, polyurethane, and epoxy systems, and formats, including waterborne, solvent-borne ...

The best neutral density filter will help you capture creative long exposures to blur movement in landscapes – even in the middle of a bright summer's day With neutral density filters, or ND filters, ...

In this mind-bending series, Jim Al-Khalili explores the vast range of size in the universe, from tiny atoms to gigantic, interconnected galaxies.

At the nanoscale level of individual CNTs, mechanical strain induces significant alterations in their electronic band structure, particularly affecting the bandgap and density of states ... reinforced ...

Propolis is a resinous product collected by bees from plant exudates to protect and maintain hive homeostasis. Propolis has been used therapeutically for centuries as folk medicine. Modern research ...
