Eliminating nonuniform geometric effects for long-term stable electrochemical extraction of high-purity titanium.

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.
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
Electrorefining of low-grade titanium is one of the strategies for achieving high-purity titanium. However, the presence of nonuniform geometric effects would be induced to impact the nonuniform geometric distribution of overpotential, leading to impurity dissolution and nonuniform Ti deposition. Here, in situ high-temperature characterizations on the molten salt electrorefining process are applied to establish an anodic dissolution principle for quantitatively evaluating nonuniform geometric effects of electrode. For eliminating the nonuniform geometric effects, coaxial anode-cathode configurations are designed to promote the nonuniform anodic dissolution and nonuniform cathodic deposition. Consequently, the geometric uniformity of titanium products on the cathodes is substantially enhanced, and thus, long-term stable electrorefining process (~12 hours, ~330% increment compared to the electrode of reference configuration) and highly purified titanium products (99.2%) are achieved.
