Ultramafic Alteration and the Cooling of Earth and Mars
Published 2024“…I show that the same high-surface-area clay minerals which bury organic carbon on Earth are prevalent enough on Mars to store the bulk of its initial 1-4 bar atmosphere as adsorbed methane. I postulate that this methane was formed abiotically during hydrothermal alteration of ultramafic rocks, a process which is observed in ultramafic systems on Earth. …”

Isolated low temperature heat release from binary blends of iso-octane, n-heptane and ethanol in a spark ignition engine
Published 2024“…The blends were tested with inlet temperatures of 40°C to 140°C at an inlet pressure of 0.9 bar (absolute). <br> To simulate the effect of high temperature combustion residuals, a skip spark duty cycle was employed for ignition of a PRF80 blend. …”

Synthesis and reactivity of electron-deficient phosphorus(III) compounds
Published 2017“…Transient formation of [1a]2+ and [1b]2+ is evidenced by activating C-F bonds of trifluorotoluene and [BArF4]- (ArF = (CF3)2-C6H3) anion. The replacement of carbodiphosphorane 1 with more nucleophilic and sterically less demanding carbodicarbene ligand {C6H4(MeN)2C}2C, 2 resulted in a series of P-dications [{C6H4(MeN)2C}2C.PR]2+ (R = NiPr2, Ph, OMe, tBu, Cl) whose spectroscopic and structural features are presented. …”

Development of superhydrophobic ceramic membrane decorated with flake-like structure by two-step synthesis for seawater desalination by membrane distillation
Published 2024“…It displayed contact angles (CAs) of 155.9° for water, 144° for water/ethanol, 129° for palm oil, and 112° for engine oil, with a liquid entry pressure (LEP) of 5.2 bar Furthermore, the membrane performance was tested in a direct contact membrane distillation (DCMD) at 70 °C using a solution that simulated real seawater conditions, including sodium chloride (NaCl) at 35 g/L, sodium sulfate (Na2SO4) at 1.2 g/L, sodium carbonate (Na2CO3) at 1 g/L, and humic acid at 8 mg/L. …”

Thermodynamic modelling of adsorption isotherms and kinetics for gas storage and cooling applications
Published 2015“…The experimental setup is extensively utilised to measure the amount of methane uptake for the temperatures ranging from 120 K to 303 K and pressures up to 10 bar. The proposed isotherm model is validated with the experimental data of silica gel + water and AQSOA-Z01, Z02, Z05 + water systems, and explains the S-shaped isotherms within acceptable error ranges (±5%), as compared with Langmuir and Toth isotherm equations. …”

Electrical machine fault analysis and modelling by using electromagnetic approach
Published 2016“…The study in this thesis indicates that the stator inter-turn winding short-circuit fault can also result in irreversi-ble demagnetization for the bar-wounded permanent magnet machines. Moreover, an analytical model is designed to predict winding short-circuit current, which significantly reduce the time required by finite element method to assess machine irreversible demagnetization. …”
