As of 2026-09-11 · the last 10 years
Dubnium’s research intensity has fallen to about 9% of its own all-time peak, a steady decline from a high point reached in 2009, which lies outside this ten-year window.
Research intensity ran from about 20% of the element's own all-time peak in 2016 to about 9% 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, dubnium has one of the smaller research literatures of any element.
The number of papers involving the element fell from about 22 in 2016 to about 8 in 2025 (0.36x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research.
The research landscape for dubnium is dominated by a single community: Synthesis and Decay of Superheavy Elements and Heavy-Ion Collision Physics. This group accounts for 100% of the element's recent research, a rise from 92.9% in the previous period. Dubnium is a minor presence in this much larger community, with under 1% of its papers involving the element, yet it remains the sole focus of dubnium-specific work. The community’s activity is anchored by recent efforts to validate chemical separation techniques, such as a 2026 paper on vacuum chromatography with subsecond radioisotopes, cited once, and studies on nuclear decay, including a 2024 analysis of the spontaneous fission of Db-255, cited about 11 times.
Two other communities show negligible or declining involvement. Actinide Chemistry and Nuclear Fuel Materials holds a steady 0% share of dubnium research, with the element appearing in under 1% of that community's papers. Nonlinear Optical Crystals for Ultraviolet and Infrared Light Conversion saw its share decline from 7.1% to 0%, where dubnium is also a minor presence, appearing in under 1% of papers. The remaining research communities hold a combined 0% share, indicating that the literature has consolidated entirely around superheavy element synthesis and decay physics.
The most-cited paper in the window, "Vacuum Chromatography of Tl on SiO2 at the Single-Atom Level" (2016), cited about 33 times, belongs to the dominant synthesis community, highlighting the continued focus on chemical characterization of these short-lived isotopes.
