As of 2026-09-11 · the last 10 years
Research intensity has settled at about 88% of the element's all-time peak, a level reached after a steady decline from the window's start.
Research intensity ran from about 99% of the element's own all-time peak in 2016 to about 88% in 2026 — a steady decline, and the all-time peak (2015) lies before this window. Over the same span its share of research attention across all elements held steady. Among the 118 elements, carbon has one of the largest research literatures of any element.
The number of papers involving the element rose from about 318,913 in 2016 to about 769,332 in 2025 (2.41x). 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 material research communities in this window are defined by carbon’s role in structural and surface applications. Carbon Fiber Reinforcement in Structural Polymer Composites accounts for about 11.8% of the element's recent research, a steady share compared to the previous period. This community focuses on the mechanical integration of carbon fibers and nanomaterials into epoxy and polymer matrices for structural reinforcement, with carbon serving as one strand of a broader community where about 27% of its papers involve carbon. Key work includes a 2022 review on global carbon fibre composite developments, cited over 970 times, and a 2020 study on the biodistribution of carbon nanotubes, cited over 1,200 times.
Carbon Nanomaterials and Diamond-Like Films for Coatings represents a declining share, dropping from 17.1% to about 10.7% of recent research. This group concentrates on synthesizing carbon nanotubes, amorphous films, and silicon carbide composites for protective surface applications. Here, carbon is also one strand of a broader community, with about 28% of its papers involving the element. A 2023 review on Raman spectroscopy of carbon materials, cited over 1,000 times, anchors this field, alongside a 2025 analysis of disordered carbon materials, cited over 240 times.
Carbon-Based Sorbents for Direct Air Capture holds a steady share of about 9.5% of the element's recent research. This community focuses on porous carbon, graphene oxide, and activated carbons as materials for direct air capture and storage. Carbon is one strand of a broader community here, with about 17% of its papers involving the element. The field is anchored by the 2021 IPCC special report on carbon dioxide capture and storage, cited over 4,900 times, and a 2024 Nature paper on covalent organic frameworks for air capture, cited over 390 times.
Overall, the composition of carbon’s research has shifted slightly away from coatings and toward other areas, with the remainder of the literature holding a rising share of about 67.9%.
