Conceptual liquid-metal electrochemistry and reported carbon productsA conceptual three-electrode cell shows an electrolyte above liquid metal, with carbon dioxide bubbles rising from across the reactor base through the liquid metal and into the electrolyte. WE, RE and CE denote working, reference and counter electrodes; their positions are illustrative. The bubble paths show distributed gas delivery, not an exact outlet count or measured bubble sizes. Separate motifs represent carbon black aggregates, a graphene sheet and layered graphitic carbon. They do not reproduce the published apparatus, measured bubble sizes or experimental product structures.LIQUID-METAL ELECTROCHEMISTRYREPORTED CARBON PRODUCTSWERECEELECTROLYTELIQUID METALCO₂ SUPPLY ACROSS REACTOR BASEINTERFACECARBON BLACKGRAPHENEGRAPHITICAggregatesA carbon sheetLayered sheetsCONCEPTUAL CELL · ILLUSTRATIVE ELECTRODE POSITIONSSTRUCTURES NOT TO SCALE
CO₂ bubbles rise from across the reactor base. Gas delivery is distributed across the bottom of this conceptual cell. Bubbles rise through the liquid metal and into the electrolyte. Electrode positions and bubble paths are illustrative. WE: working electrode; RE: reference electrode; CE: counter electrode.

Illustrative pipeline surge envelope An unscaled conceptual pipeline profile runs from a pump over a summit to a fixed-level reservoir. Steady, upper and lower hydraulic grade lines meet at the reservoir water level; local entrance and exit losses are omitted. A shaded low-pressure region marks where the lower envelope falls below the pipe elevation, indicating sub-atmospheric gauge pressure. It does not establish vaporous column separation, which depends on absolute pressure and the liquid’s vapor pressure. The pipe-rating limit follows the pipeline elevation. This is not a computed study or client data. PIPELINE SURGE ENVELOPE STEADY & TRANSIENT HYDRAULICS · PFD / P&ID · HAZOP / LOPA / SIL
Reading a pipeline surge envelope. Shading marks sub-atmospheric pressure where the lower hydraulic grade line falls below the pipe elevation. Cavitation requires a separate comparison with vapor pressure. The curves meet at a fixed-level tank; local losses are omitted.

Infrastructure project consulting

Worked on public-private partnership, business-case and lender technical advisory engagements for infrastructure projects across the GCC.

Public-private partnership risk allocation and the lender technical advisory role An illustrative PPP risk-allocation spectrum runs from public authority to private partner. Design and build and operations are shown on the private side as examples. Open bars across the spectrum mark site and consents, demand and revenue, and change in law as contract-dependent. Force majeure is shown shared illustratively, with consequences governed by the contract. A bracket denotes independent technical due diligence by a lender technical adviser. Positions are qualitative, not percentages or a universal allocation, and this is not client data. PPP RISK ALLOCATION · ILLUSTRATIVE OPEN BARS: CONTRACT-DEPENDENT · POSITIONS ARE QUALITATIVE
Risk allocation depends on the project and contract. Open bars denote variable allocations for site and consents, demand and revenue, and change in law. The other positions illustrate possible allocations. A lender technical adviser provides independent technical due diligence; the chart is not client data.Open full-size PPP diagram

04 / About

In the lab.
And beyond it.

I’m a chemical engineer and doctoral researcher at Khalifa University in Abu Dhabi, working on liquid-metal electrochemistry and the conversion of CO₂ into solid carbon.

My experience also spans process design, hydraulic and surge studies, and infrastructure consulting across the GCC. That work informs the questions I bring back to the lab.
