Microstructural effects and mechanism of bcc-hcp-bcc transformations in polycrystalline iron
Cycling the α↔ε transformation in polycrystalline Fe is investigated using in situ x-ray diffraction under quasihydrostatic conditions. The forward α→ε transformation starts at 14±1 GPa and completes at 18±1 GPa while the reverse ε→α transformation starts at 10.5±0.5 GPa and completes at 6±1 GPa. The anomalous evolution of c/a ratios of ε-Fe measur...
The spatial dynamics of droughts and water scarcity in England and Wales
Water scarcity occurs when water demand exceeds natural water availability over a range of spatial and temporal scales. Though meteorological and hydrological droughts have been analyzed over large spatial scales, the impacts of water scarcity have typically been addressed at a catchment scale. Here we explore how droughts and water scarcity intera...
Retrospective and prospective evaluations of drought and flood
Climate extremes will be intensified and become more frequent One of the regions where this is the case is the US. Gulf coast region. This region is susceptible to the impacts of climate extremes. This region has recently experienced large amounts of economic damages caused by high-impact hurricanes and floods. Meanwhile, drought can also pose seri...
Synergetic effect of secondary nucleation and growth on the lithium carbonate particle size in the gas-liquid reactive c...
In this study, the gas-liquid reactive crystallization of LiCI-NH3 center dot H2O-CO2 was adopted to produce Li2CO3. The weakly alkaline nature of NH3 center dot H2O in the absence of any recarbonation process resulted in a unimodal and easily controllable particle size distribution (PSD) of the obtained Li2CO3. The reaction temperature significant...

A novel method for assessing climate change impacts in ecotron experiments
Ecotron facilities allow accurate control of many environmental variables coupled with extensive monitoring of ecosystem processes. They therefore require multivariate perturbation of climate variables, close to what is observed in the field and projections for the future. Here, we present a new method for creating realistic climate forcing for man...
Sustainable lead management in halide perovskite solar cells
Despite the rapid development of perovskite solar cells (PSCs) toward commercialization, the toxic lead (Pb) ions in PSCs pose a potential threat to the environment, health and safety. Managing Pb via recycling represents a promising approach to mitigating its toxicity. However, managing Pb from commonly used organic solvents has been challenging d...
Enhanced Hydromagnesite Process for CO2 Sequestration by Desilication of Serpentine Ore in NaOH Solution
A new CO2 fixation process was highly enhanced by desilication of serpentine ore with concentrated NaOH solution and NH3 recycling. In the process, desilicated serpentine containing up to 83 wt % MgO after leaching is treated by NH4Cl solution, from which MgCl2 solution and NH3 gas are generated and are used to capture CO2. Hydromagnesite is produc...
