Abstract. High-purity copper sulfides including CuS, Cu 1.75 S and Cu 2 S were synthesized using an easy and controllable two-step heating method in a mixed solution of ethylene glycol and triethylenetetramine. Petal-like CuS, near-spherical Cu 2 S, and regular hexagonal Cu 1.75 S were obtained by simply changing the solvent volume …

3.1 Anilite (Cu 7 S 4). Several polymorphs of copper sulfide, of general formula Cu x S (1 ≤ x ≤ 2), have been characterized. In these structures, the location of Cu atoms in the close-packed S lattice is not well identified and their positions change as a function of the composition (x).In a copper-rich environment, the experimentally …

Copper sulfide minerals require the use of acid and an oxidizing agent to break the mineral lattice and release Cu2+ into solution ( Sherrit, Pavlides, & Weekes, 2005 ). Elemental copper found in nature can be leached by either oxygen or ferric ion: (15.6a) Metallic copper: Cu + 0.5 O 2 + H 2 SO 4 → Cu 2 + + SO 4 2 − + H 2 O.

Bovine serum albumin (BSA)-encapsulated copper sulfide nanocrystals (CuS NCs) were prepared by heating an alkaline solution containing copper ions and BSA without an additional sulfur source. At a high BSA concentration (0.8 mM), nanoassembly of the as-formed CuS NCs occurs to form BSA–CuS NCs as a result of the formation of …

Red copper: It's an alloy of redstone and regular "industrial grade" copper. The mod makes use of many alloys, but these two are the most important ones. The furnace is slow, so it would be a good idea to make multiple (or to steal them from a factory structure). Many of the recipes are additive, meaning you'll get 2 ingots from alloying.

Copper sulfide allows for high-performance sodium ion storage, yet its sodiation mechanism is poorly understood. Here, the authors examine the atomic structures of sodiated phases via in situ ...
