Every breakthrough brings new words with it:
UK breakthrough could slash cement CO2 emissions

Electric cement - reactivated recycled cement using an electric arc furnace powered by the slag that was originally used to recycle steel, and via the Cambridge University's Department of Engineering.
Transparent metamaterial for energy-efficient regulation in building can clean itself like a lotus leaf
May 2024, phys.org
Polymer-based micro-photonic multi-functional metamaterial - made of microscopic pyramids of silicone and allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf.

Some of the matter swirling toward the black hole was redirected into dual jets firing in opposite directions. We see a gamma-ray burst when one of these jets happens to point directly at Earth.

New material records mechanical stress through luminescence
Jun 2024, phys.org
Mechanoluminescent materials - exhibit luminescence when mechanically stimulated by recording mechanical stress history through a luminescent effect called an afterglow, which is stored for a long time, and uses a power supply of Pr-doped Li0.12Na0.88NbO3 (LNNO) applied to the surface and then irradiated with a flashlight.

Newly created super-black wood can improve telescopes, optical devices and consumer goods
Jul 2024, phys.org
Nxylon - Thanks to an accidental discovery, researchers at the University of British Columbia have created a new super-black material that absorbs almost all light. They were experimenting with high-energy plasma to make wood more water-repellent. However, when they applied the technique to the cut ends of wood cells, the surfaces turned extremely black.The team named and trademarked their discovery Nxylon (niks-uh-lon), after Nyx, the Greek goddess of the night, and xylon, the Greek word for wood. It's made from basswood, a tree widely found in North America. It can replace expensive and rare black woods like ebony and rosewood for watchfaces, and it can be used in jewelry to replace the black gemstone onyx.
