Research Facilities

We have several research labs which are located in School of Chemical Engineering, University of Adelaide, City Campus. These labs are built to provide key research capabilities in nanomaterials synthesis, products and device development their testing and prototyping needed to support our industry projects. Our specific labs are:
(1) Nanomaterials synthesis
(2) Graphene and 2D materials lab,
(3) Surface engineering  
(4) Device fabrication/prototyping
(5) Materials/device characterization
(6) Sensors lab

Nanomaterials synthesis

In this lab we have established many required facilities for lab scale synthesis of nanomaterials with different chemical composition (metals, MeO, graphene, nanocarbons, MOFs etc) with different shapes and dimensions (0D, 1D, 2D, and 3D) where broad range of preparation techniques are used such as.
• Chemical batch synthesis
• Flow chemistry synthesis
• Hydrothermal (high pressure)
• Thermal/pyrolysis
• Thermal (CVD)
• Micro-plasma synthesis
• Microwave
• Ultrasonication
• Ball milling
• High-sheer mixing
• Spray drying
• Freeze drying

Graphene Research Lab

Graphene research lab was established in 2016 with goals to support the Group research activities on graphene and 2D materials. The lab was the head of ARC graphene Research hub funded by ARC and industry partners (2017-2022) and was key lab for translation of graphene research and new products development.

This lab has broad range of preparation techniques and developed methods for synthesis graphene and 2D materials which are used for development of new products and devices for industry collaborative projects (additives, paints, filaments, sensors, supercapacitors, antenna etc)  More details in: https://arcgrapheneresearchhub.com.au/

Surface Engineering

Surface engineering is key process for many projects to support fundamental research and applied projects including biomedical implants, sensing device development and fabrications. Following surface engineering methods are available and used in our labs.
• ALD (thermal, plasma)
• CVD (3)
• Plasma (atmospheric)
• Plasma (vacuum)
• Plasma (particles, corona)
• Hydrothermal surface modification/growth
• UV/Ozone
• Spin, dip, spray coating
• Thermal metal deposition
• Electrochemical (deposition anodization, etching)
• Plasma Electrolytic Oxidation (PEO
• Laser scribing

Device fabrication/prototyping/scaling up

Our industry partners have a strong requirements to provide more evidence of scalability and confidence of  developing products and technologies with higher TRL level. To address these needs we established prototyping capabilities with several fabrication equipment for 5L and 10 Synthetic, semi industrial 2D printers for fabrication sensors, extrusion facilities to make filaments for 3d printing equipment etc.
• Graphene and 2D materials preparation (incl funcationalizations): kg scale
• Preparation of graphene and conductive inks: kg scale
• Preparation of graphene additives for paints, concrete, polymer composites,
• 2-d printing of sensing devices (ink-jet and spray)
• 3-D printing: polymer and polymer composite parts
• 3-d printing of medical implants: Ti alloys (with IPAS)
• Fabrication of filaments by extrusion process: for 3-d printing
• 3-d bioprinting and formulation bionks
• Roto printing graphene and 2d materials films
• Development of processing technology for partners
• Development of products/formulations for partners
• Development of devices/systems for partners

 

Characterization facilities

Characterization of properties of prepared materials (chemical, physical, mechanical, electrical, thermal) and performance of fabricated products and devices is the core of our R&D activities. To allow our students and researchers to characterized  materials and devices immediately after preparation we have many available methods in our labs. Other instruments such as SEM/EDAX,TEM, AFM, Raman, XRD etc are available at Adelaide microscopy and School analytical lab. We specially established protocols and developed some new methods for characterization of graphene materials with implantation of ISO standards.
• Light Microscopy
• UV/VIS, PL, portable Raman
• XRF
• Particles size (PSD)
• Surface area (BET
• TGA and TGA/FTIR
• Electrochemical system
• Electrical Conductivity
• Thermal properties
• Flammability

Sensors Research lab

Our team is working on development of broad range of graphene based gas and VOC sensors for environmental detection, medical diagnostic (biomarkers), agriculture and food  control and defence. For these sensors we developed and prepared sensing materials  in our labs and fully fabricated using our printing technologies.  For testing their sensing characteristics we developed own gas  and VOC calibration standards and chambers which are used for their characterization.
