Porosity Data, Frank Huang

Energize New Mexico (NSF EPSCoR Track 1 IV)

This workbook contains several membrane porosity values for both 1212 and 15113 membranes. The porosity values were calculated individually using separate, distinct membrane samples. The gravimetric method was used for calculating porosity. The 1212 membranes were fabricated using 12% PVDF polymer powder, 12% ethylene glycol (EG), and 76% N-methy-2pyrrolidinone (NMP); while the 1513 membranes were fabricated using 15% PVDF, 13% EG, and 72% NMP. High porosity is beneficial in membrane distillation because porosity is positively correlated with vapor transport. By measuring and controlling membrane porosity, we are able to fabricate membranes which are performance optimized.

Cloudpoint Analysis, Frank Huang

Energize New Mexico (NSF EPSCoR Track 1 IV)

Quantitative cloud-point analysis allows for control of membrane characteristics like macro-void structure within a hollow fiber. Cloud-point is the point when instantaneous demixing occurs in membrane fabrication. Polyvinylidene fluoride (PVDF) membrane solution was tested with various solutions of Isopropyl Alcohol (IPA) and water to find the point of instant membrane formation. Currently there are no well-defined methods for measuring cloud-point. The data in this spreadsheet represents turbidity data using 12 and 15 ml samples in a turbidimeter. The transmittance data was gathered from a spectrophotometer using a laser and photo sensor. Transmittance data was from a spectrophotometer in the lab …

New Masson Water Chemistry, Frank Huang

Energize New Mexico (NSF EPSCoR Track 1 IV)

This workbook contains the chemical analysis of a geothermal water sample taken at the inlet of the membrane distillation pilot plant located at Masson Geothermal Greenhouse. Additionally, this workbook contains the calculations necessary for simulating the geothermal water in a laboratory setting. These calculations are important to the membrane distillation bench-scale experiments, because they allow us to simulate the geothermal water at the pilot-plant; this allows us to study the fouling potential (precipitation behavior) of the water in a controlled laboratory setting.

Facile Synthesis Of Hierarchical Mos2, Hongmei Luo

Energize New Mexico (NSF EPSCoR Track 1 IV)

Herein, we prepared hierarchical MoS2-carbon (MoS2-C) microspheres via continuous and scalable ultrasonic nebulization assisted route. The structure, composition, electrochemical properties are investigated in detail. The MoS2-C microspheres consist of MoS2 nanosheets with a few layers bridged by carbon, which separates the exfoliated MoS2 layers and prevents their aggregation and restacking and thus leading to improved kinetic, enhanced conductivity and structural integrity. The novel architecture offers additional merits such as overall large size, high packing density, which promote their practical applications. The MoS2-C microspheres have been demonstrated with excellent electrochemical performances in terms of low resistance, high capacity even at large …

Nb2o5 Anode, Hongmei Luo

Energize New Mexico (NSF EPSCoR Track 1 IV)

Nb2O5 NCs/rGO was synthesized by controllable hydrolysis of niobium ethoxide and followed by heat treatment at 450 Ã¯â€šÂ°C in flowing forming gas. Transmission electron microscopy (TEM) images showed that Nb2O5 NCs with average particle size of 3 nm were uniformly deposited on rGO sheets and voids among Nb2O5 NCs existed. The architecture of ultrafine Nb2O5 NCs anchored on highly conductive rGO network and can not only enhance charge transfer and buffer the volume change during sodiation/desodiation process, but also provide more active surface area for sodium ion storage, resulting in superior rate and cycle performance. Ex situ XPS analysis revealed …

Nb-Oxides For Energy Storage, Hongmei Luo

Energize New Mexico (NSF EPSCoR Track 1 IV)

Their high potential window can prevent the formation of lithium dendrites, as well as the rich redox chemistry (Nb5+/Nb4+, Nb4+/Nb3+) makes them very promising electrode materials. The unique chemical stability in acid condition is favorable for practical fuel cell operation. In this review, we summarized the recent progresses using niobium-based oxide as electrodes for batteries (LIBs, sodium-ion batteries (SIBs), and vanadium redox flow batteries (VBRs), SCs, and fuel cell applications. Moreover, crystal structures, charge storage mechanisms in different crystal structures, and the electrochemical performances in terms of their specific capacitance/capacity, rate capability, and cycling stability of niobium-based oxide are discussed. …

New Mexico Abandoned Uranium Mines Study, Virginia Mclemore

Energize New Mexico (NSF EPSCoR Track 1 IV)

Mining has aided in the economic and social development of New Mexico as early as the 1500's. One of the earliest gold rushes in the West was in the Ortiz Mountains (Old Placers district) in 1828, 21 years before the California Gold Rush in 1849. Many of these mines were immediately abandoned when insufficient minerals were found, others were abandoned later when poor economics of the commodity made mining unprofitable. Miners operating on federal lands had little to no requirement for environmental protection until the 1960s and 1970s, although the dumping of mine wastes and mill tailings directly into the …

Sulphur Creek Watershed Water Chemistry, Rebecca Bixby

Energize New Mexico (NSF EPSCoR Track 1 IV)

The Sulphur Creek watershed, located on the western border of the Valles Caldera National Preserve (VCNP), New Mexico, is an example of a system with geothermally influenced surface waters that may impair confluent waters. The relationship among low pH, naturally occurring high concentrations of metals, and intermittent flow in Alamo Canyon (AC) and the Sulphur Creek watershed in the VCNP may be a contributing factor to the low diversity of algal assemblages in waters in AC that are fed by geothermal springs compared to algal assemblages located in downstream reaches of the Sulphur Creek watershed. This hydrologic connection is likely …
