Copper (Cu) — 10-Year Trends

As of 2026-09-25 · the last 10 years

Copper’s research intensity currently sits at about 37% of its all-time peak, a level that has steadily declined since the window began, with the historical peak occurring well before this period.

Research intensity ran from about 43% of the element's own all-time peak in 2016 to about 37% in 2026 — a steady decline, and the all-time peak (1979) lies before this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, copper has one of the largest research literatures of any element.

The number of papers involving the element rose from about 74,655 in 2016 to about 158,370 in 2025 (2.12x). That matches the growth of the literature as a whole over the same years: the general tide of scientific output, not a surge specific to the element.

The literature is composed of three primary research communities, each representing a distinct application of the element. The largest is Copper Nanoparticle Synthesis and Antimicrobial Activity, which focuses on the green synthesis of copper nanoparticles and their antibacterial effects. Here, copper is a minor presence in a much larger community, appearing in about 6% of its papers. This community holds about 8.7% of copper’s recent research, a steady share compared to the previous period. A key paper in this area, Green synthesis of nanoparticles: Current developments and limitations (2022), has been cited over 1,600 times.

The second community, Copper Homeostasis and Wilson Disease in Clinical Nutrition, examines copper metabolism, deficiency, and the diagnosis of Wilson disease, often alongside zinc interactions. In this field, copper is one strand of a broader community, involved in about 14% of its papers. It accounts for about 5.7% of copper’s recent research, maintaining a steady direction. The work is anchored by Copper induces cell death by targeting lipoylated TCA cycle proteins (2022), a Science publication cited over 5,000 times, which highlights the element’s role in cellular mechanisms.

The third community, Copper Recovery from Chalcopyrite and Printed Circuit Boards, deals with leaching and extraction processes to recover copper from sulfide ores and electronic waste. Copper is a minor presence here, appearing in about 8% of the community’s papers. This area represents about 5.6% of copper’s recent research, also showing a steady trend. A relevant study, A comprehensive review on the recycling technology of silicon based photovoltaic solar panels: Challenges and future outlook (2024), has been cited over 230 times.

Overall, the composition of copper research has remained stable, with no single community gaining or losing significant share relative to the others. The remainder of the literature, comprising other smaller communities, holds about 80% of the element's recent research, a share that has remained steady.
