Electronic vs Ionic limitations to electrochemical performance in Li4Ti5O12-based organic suspensions for lithium-redox flow batteries
Published 2014“…Here, we report the electrochemical response of the LTO/KB anolytes vs. lithium as function of the cycling rate in static mode (i.e. no flow) and using a home-made cell. The KB content was fixed at 3 wt% while the LTO content was varied between 15 and 25 wt%. …”

Prospects Of Amino Acids And Ionic Liquids As Natural Gas Hydrate Inhibitors For Offshore Flow Assurance
Published 2018“…The inhibitors tend to show better hydrate inhibition effect at low pressures (40 bars) and their inhibition effect decreases as the pressure rises. At the same concentration (10 wt%), the ammonium-based ionic liquid [EA][Of] provided the inhibition effect similar to MEG and at the higher concentration (20 wt%) the amino acid glycine provided better hydrate inhibition effect than the MEG. …”

Improved flexible, controlled dielectric constant material from recycled LDPE polymer composites
Published 2016“…In this study, recycled low density polyethylene (RLDPE) is developed with the addition of aluminum oxide (Al2O3) to have new polymer composites. The following wt% were used of the filler (1, 4 and 6 wt%). Tensile properties, Hardness, scanning electron microscopy (SEM) thermo gravimetric analysis, differential scanning calorimetry and dielectric properties were studied for these composites. 4 wt% Al2O3/RLDPE composites showed the optimum values of 15.52, 180.8 and 59.72 MPa for the tensile strength, tensile modulus and hardness were reported. …”
