Robiul Hossen

Hello 👋, I am Robiul. I work as a mechanical engineering researcher based at City University , Savar. I care about bio nanocomposites and hybrid composites, honest reporting in venues like Scientific Reports, and careful industry QA/QC. The full timeline, references, and project list are in my CV (PDF).

Day to day I connect experiments to data: mechanical and thermal tests, microscopy, spectroscopy, and simple structural models when a design question needs a number, not a story.

Before graduate style research intensified, I worked in industry on polymer QC: UTM, impact, Vicat, hydrostatic checks on CPVC and UPVC. English scores: IELTS 7.5 overall.

  • Prolifter Limited (engineering and handling) and Pii Marketers (digital). Public URLs for both belong in the CV when you publish them.

Degrees: B.Sc. ME (CGPA 3.27) from City University, and a Diploma in Power Engineering from Cumilla Polytechnic (CGPA 3.35).

Interests in one line: Nanocomposites, fiber reinforced composites, materials characterization, nanomaterials, smart materials.

Research projects

Bio nanocomposites and hybrid composites

(NARP / IUBAT)

Research Assistant with Nayem's Association for Research and Publication, Assoc. Prof. Dr. Nayem Hossain's Lab (Dept. of Mechanical Engineering, IUBAT). Work includes MgO nanoparticle loading in jute epoxy systems (mechanical testing, FTIR, SEM), recycled denim epoxy and jute denim hybrids with ASTM testing and TGA/DSC, and FEA based structural optimization of naval UNREP/RAS stations with genetic algorithms (about 10% weight reduction, SOLAS II-1).

Pyrometallurgical zinc recovery

(City University)

Research Assistant, Department of Mechanical Engineering, City University (July to December 2023). Project on extracting pure zinc from bottom zinc dross (galvanizing waste) via pyrometallurgical liquation refining (99.54% purity achieved), with characterization using XRF, XRD, OES, tensile, hardness, and impact testing. BMTF funded ($2,000).
