Djurleite is a copper sulfide mineral of secondary origin with formula Cu 31 S 16 that crystallizes with monoclinic -prismatic symmetry. It is typically massive in form, but does at times develop thin tabular to prismatic crystals.

Named in 1962 by Eugene Holloway Roseboom, Jr. in honor of Dr. Seved Djurle [August 18, 1928 Sweden – October 4, 2000 Sweden], professor of chemistry at University of Uppsala, Sweden who first synthesized the synthetic equivalent before the mineral was discovered.

1994年4月1日 · Djurleite and digenite (dg) bands are intergrown, with (111) dg, parallel to (100) dj, thereby creating a cubic-hexagonal alternation in the sequence of close-packed layers. The typical orientational relationship between coexisting djurleite and chalcocite is where [001] cc is parallel to [100] dj , and [010] cc is parallel to one of the 〈010 ...

The crystal structure of djurleite has been solved in space group P 2 1 / n, the monoclinic cell having parameters a = 26.897, b = 15.745, and c = 13.565 angstroms; β = 90.13 °; and a content of 248 copper and 128 sulfur atoms.

2022年6月28日 · The formation of djurleite copper sulfide with a Cu vacancy enables faster H + ion transport and shows improved HER activity with a remarkably lower overpotential of 164 mV at 10 mA/cm 2, whereas cobalt-incorporated copper sulfide undergoes cation exchange during synthesis and shows elevated OER activity with a lower overpotential of 240 mV at ...

久輝銅礦 (Djurleite). Djurleite是次生起源的硫化銅礦物，分子式為Cu31S16，以單斜晶棱鏡對稱性結晶。 它通常呈塊狀，但有時會形成薄板狀到棱柱狀晶體。

A highly unusual large pseudomorph from this extinct open pit New Mexico copper mine. Chalcocite and djurleite, gray to black copper sulfides, have pseudomorphed a flattened section of fossilized wood. Some of the chalcocite and djurleite has altered to green malachite. A major bonus is the pseudomorphed fossil wood resting on the layered ...
