Materials Data on Ir2Os(NCl)10 by Materials Project

OsCl6(IrN3Cl2)2(N2)2 crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two hexachloroosmium molecules, four nitrogen molecules, and four IrN3Cl2 clusters. In each IrN3Cl2 cluster, Ir4+ is bonded in a tetrahedral geometry to three N+0.60- and one Cl1- atom. There is two shorter (1.73 Å) and one longer (2.00 Å) Ir–N bond length. The Ir–Cl bond length is 2.27 Å. There are two inequivalent N+0.60- sites. In the first N+0.60- site, N+0.60- is bonded in a bent 120 degrees geometry to one Ir4+ and one Cl1- atom. The N–Cl bond length is 1.67 Å. In the second N+0.60- site, N+0.60- is bonded in a single-bond geometry to one Ir4+ atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one N+0.60- atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Ir4+ atom.

Development of the Global Ozone Lidar Demonstrator (GOLD) Instrument for Deployment on the NASA Global Hawk

A compact ozone (O3) and aerosol lidar system is being developed for conducting global atmospheric investigations from the NASA Global Hawk Uninhabited Aerial Vehicle (UAV) and for enabling the development and test of a space-based O3 and aerosol lidar. GOLD incorporates advanced technologies and designs to produce a compact, autonomously operating O3 and aerosol Differential Absorption Lidar (DIAL) system for a UAV platform. The GOLD system leverages advanced Nd:YAG and optical parametric oscillator laser technologies and receiver optics, detectors, and electronics. Significant progress has been made toward the development of the GOLD system, and this paper describes the objectives of this program, basic design of the GOLD system, and results from initial ground-based atmospheric tests.

Techno-economic assessment of emissions mitigation technologies for post-combustion CO2 capture using AMP/PZ

Minimizing the environmental impacts of amine-based post-combustion carbon capture technologies is essential for meeting environmental permitting regulations and ensuring public acceptance. Experimental test campaigns at the CO₂ capture pilot plant in Niederaussem using CESAR1 demonstrated that integrating available emission abatement technologies can significantly reduce the concentration of amines and degradation products in CO₂-depleted flue gas to below the detection limit of an infrared spectrometer. The study confirmed that proprietary dry bed technology (OEASE Aerozone™) or a second water wash can lower AMP and PZ emissions to below 1 mg/Nm³. However, to achieve very low NH₃ emissions below 2 mg/Nm³, an acid or other chemically active wash downstream of the water wash is required. A configuration with a dry bed or a double water wash results in a carbon capture cost (CCC) of 44 €/tCO₂, and a CO₂ avoided cost (CAC) of 86 €/tCO₂. A configuration with an acid wash increases the CCC to 47 €/tCO₂ and the CAC to 90 €/tCO₂ due to the amine losses in the acid waste and its treatment.
