The scientific world’s newest 'miracle material' might not actually exist—it might just be a bunch of regular old dust that someone misidentified.

The Takeaway
Many scientists thought they had created "borophene," a miracle 2D material. This study shows that the standard methods used to make it actually just produce oxidized junk and carbon, debunking years of supposed breakthroughs.
From the abstract
The rapid rise of publications claiming the synthesis of free-standing borophene via top-down approaches has generated intense excitement, but also deep ambiguity, around the true nature of the resulting materials. Here we demonstrate that, under representative bath-sonication and mechanical milling conditions, no known borophene polymorph is formed. We have compared sonication of boron powder in water, hydrogen peroxide, organic solvents, and ball-milling in controlled gas atmospheres treatment
