1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Metal-doped nanoporous carbon (MDNC) derived from core-shell metal-organic frameworks (MOFs) exhibits temperature-dependent thermoelectric behavior that is highly sensitive to nanoporous structure and surface interactions. In this study, a pellet-based approach is employed to enable systematic investigation of the Seebeck coefficient and electrical conductivity of MDNC as a function of temperature. Differential scanning calorimetry (DSC) reveals a pronounced desorption process in the temperature range of 80-100 ℃, which is closely correlated with significant changes in electrical transport properties. To further elucidate this behavior, MDNC samples with different particle sizes (~ 200 nm and ~ 800 nm) are examined, demonstrating distinct temperature-dependent variations in both Seebeck coefficient and electrical conductivity. These results indicate that temperature-induced desorption plays a critical role in modulating carrier transport through changes in interfacial barriers, scattering mechanisms, and conductive pathway connectivity. The particle-size-dependent nanoporous structure further influences this behavior by altering adsorption/desorption characteristics. Overall, this study provides insight into the coupling between nanoporous structure and temperature-dependent transport behavior in MDNC, offering a framework for understanding and tuning thermoelectric responses in nanoporous carbon systems.
