Bohrium

Bohrium (Bh) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Bohrium’s research intensity has fallen to about 12% of its all-time peak, a level reached before this window opened.

Research intensity ran from about 22% of the element's own all-time peak in 2016 to about 12% in 2026 — a steady decline, and the all-time peak (2009) lies before this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, bohrium has one of the smaller research literatures of any element.

The number of papers involving the element rose from about 22 in 2016 to about 66 in 2025 (3.0x). That is faster than the literature as a whole grew over the same years, so the element gained ground in the wider body of research.

The core of bohrium’s recent research belongs to the community of Superheavy Nuclei, Heavy-Ion Collisions, and Nuclear Structure. In this field, bohrium is a minor presence in a much larger community, with under 1% of its papers involving the element. However, this community now accounts for about 100% of the element's recent research, a significant rise from about 56% in the previous period. This consolidation is anchored by recent work such as "Validating Vacuum Chromatography with Subsecond Radioisotopes of Hg for Superheavy Element Chemistry" (2026, cited once) and the earlier "Vacuum Chromatography of Tl on SiO 2 at the Single-Atom Level" (2016, cited about 33 times).

Other communities that previously held a share of bohrium’s literature have seen their influence diminish. The community of Dark Matter, Neutrino Physics, and Compact Object Astrophysics, where bohrium is also a minor presence, declined from about 33% of the element's research to zero. Similarly, the community of Selective Recovery of Platinum Group Metals from Waste Streams, where bohrium is a minor presence, fell from about 11% to zero. A 2018 paper in this latter group, "Road dust and its effect on human health: a literature review," was cited over 180 times, though it represents a peripheral connection rather than a core focus. The community of Deep Learning for Image Generation, Medical Imaging, and Anomaly Detection remained steady at zero share.

Overall, the literature has consolidated entirely around the physics of superheavy nuclei, shedding its earlier, more diffuse connections to astrophysics and materials recovery.
