Utilizing Skyline to analyze lipidomics data containing liquid chromatography, ion mobility spectrometry and mass spectrometry dimensions
<p>Lipidomics studies suffer from analytical and annotation challenges due to the great structural similarity of many of the lipid species. To improve lipid characterization and annotation capabilities beyond those afforded by traditional mass spectrometry (MS)-based methods, multidimensional separation methods such as those integrating liquid chromatography, ion mobility spectrometry, collision induced dissociation and MS (LC-IMS-CID-MS) may be employed. While LC-IMS-CID-MS and other multidimensional methods offer valuable hydrophobicity, structural and mass information, the files are also complex and difficult to assess. Thus, the development of software tools to rapidly process and facilitate confident lipid annotations is essential. In this Protocol Extension, we utilize the freely available, vendor-neutral, and open-source software Skyline to process and annotate the multidimensional lipidomic data. While Skyline was established for targeted processing of LC-MS-based proteomics data, it has since been extended such that it can be used to analyze small molecule data as well as data containing the IMS dimension. This protocol utilizes Skylines’ recently expanded capabilities, including small molecule spectral libraries, indexed retention time (iRT), and ion mobility filtering, and provides a step-by-step description for importing data, predicting retention times, validating lipid annotations, exporting results, and editing our manually validated 500+ lipid library. While the time required to complete the steps outlined here varies based on multiple factors such as dataset size and familiarity with Skyline, this protocol takes approximately 5.5 hours to complete when annotations are rigorously verified for maximum confidence.</p>

Phosphorus recovery from liquid digestate by chemical precipitation using low-cost ion sources
<p>BACKGROUND</p> <p>Phosphorus (P) recovered and recycled from agricultural waste, such precipitation of struvite (MgNH<sub>4</sub>PO<sub>4</sub>.6H<sub>2</sub>O) and calcium phosphates from the effluent after anaerobic digestion of wastes, is an important approach to developing environmentally sustainable fertilizers. However, for controlled phosphorus precipitation/recovery, it is usually necessary to supplement Ca<sup>2+</sup> or Mg<sup>2+</sup> ions; this represents more than 75% of the total operational costs and, as a result, hinders a more extensive application of this process. Therefore, there is a need to investigate alternative and low-cost cation sources to recover phosphorus by precipitation. This study investigated limestone powder as calcium source and seawater as a magnesium source for phosphorus recovery by precipitation from the liquid fraction of digestate. The main parameters affecting the efficiency of the precipitation process were assessed under (i) four different pH values and (ii) three different molar ratios (Ca or Mg: P).</p> <p>RESULTS</p> <p>The maximum phosphate removal rate was 44% for limestone powder at molar ratio 2:1 and pH 7. Higher phosphate removal using limestone powder was possibly inhibited by calcite precipitation. For seawater, the phosphate removal rate was 65% at molar ratio 2:1 and pH 10. Results of experiments using seawater at molar ratio 2:1 showed a decrease in K<sup>+</sup> concentration and phosphate, suggesting that K-struvite precipitation may have occurred.</p> <p>CONCLUSION</p> <p>Limestone powder and seawater have a great potential to be used partially or totally as ion source for industrial recovery of P, mainly due to its very low cost. The recovered product could potentially be used as soil amendment and/or as phosphate rock substitute for fertilizer production. © 2021 Society of Chemical Industry (SCI).</p>

Electrodialysis with Bipolar Membranes for the Generation of NaOH and HCl Solutions from Brines: An Inter-Laboratory Evaluation of Thin and Ultrathin Non-Woven Cloth-Based Ion-Exchange Membranes Tamara
<p>The SEArcularMINE project aims to recover critical raw materials (CRMs) from brines from saltworks, thus facing a CRM shortage within Europe. To promote a fully circular scheme, the project valorises concentrated brines using electrodialysis with bipolar membranes (EDBM) to generate the required amounts of reactants (i.e., acids and bases). Regarding the performances of new non-woven cloth ion-exchange membranes (Suez): (i) an ultra-thin non-woven polyester cloth and (ii) a thin polypropylene cloth acting as the support structures were assessed. Additionally, the anion layer includes a catalyst to promote the water dissociation reaction. The effect of current density (100, 200, and 300 Am−2) on the performance of two combinations of membranes in an inter-laboratory exercise using 2 M NaCl was evaluated. According to statistical analysis ANOVA, there was an agreement on the results obtained in both laboratories. NaOH/HCl solutions up to 0.8 M were generated working at 300 A m−2 using both combinations of membranes. Regarding the performance parameters, stack set-ups incorporating thin polypropylene membranes showed lower specific energy consumption (SEC) and higher specific productivity (SP) than ultra-thin polypropylene ones. Hence, for ultra-thin polypropylene membranes, SEC was reported to be between 2.18 and 1.69 kWh kg−1<br>NaOH and SP between 974 and 314 kg m−2 y−1.<br><br></p>
