In(Hg) is Tungsten Carbide-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Hg is bonded in a 6-coordinate geometry to six equivalent In atoms. All Hg–In bond lengths are 3.13 Å. In is bonded in a 6-coordinate geometry to six equivalent Hg atoms.
Sr(HgIn)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight equivalent Hg atoms. All Sr–Hg bond lengths are 3.57 Å. Hg is bonded in a 9-coordinate geometry to four equivalent Sr, one Hg, and four equivalent In atoms. The Hg–Hg bond length is 2.85 Å. All Hg–In bond lengths are 3.00 Å. In is bonded to four equivalent Hg atoms to form a mixture of distorted edge and corner-sharing InHg4 tetrahedra.
The mission of the National Energy Technology Laboratory (NETL), a U.S. laboratory under the Department of Energy, is to drive innovation and deliver solutions for an environmentally sustainable and prosperous energy future. Through the U.S. Department of Energy (DOE)/Fossil Energy’s (FE) Crosscutting Research Program, NETL funded Interphase Materials to develop and demonstrate a technology to improve power plant condenser efficiency. From 2018 through 2021, Interphase Materials developed THERMOPHASE, an advanced material applied to the condenser during plant operation to increase efficiency and lower fuel consumption, CO 2 emissions, and water withdrawal. THERMOPHASE was evaluated in controlled environments where improvements to heat transfer and a reduction in fouling were observed. THERMOPHASE was also applied to the main condenser of the Longview Power plant and changes to the plant performance were monitored. After two years following application of THERMOPHASE, a reduction in condenser back pressure of 0.26 ± 0.13 inHg was observed resulting in an estimated $3.35M in fuel savings, 136 million lbs. of decreased CO 2 emissions, and 1,287 million gallons reduced water withdrawal.
