The ability to fabricate state-of-the-art electronic and photonics systems on soft and deformable substrates can find tremendous opportunities in sensing, bio-engineering, robotics, health-care, and smart wearables devices. The materials and processing challenges however remain significant since most existing functional systems rely on rigid materials, with processes not well adapted to soft...
Recent developments in novel ferroelectrics (e.g. based on HfO2, AlN and ZnO) with robust polarization reversal and processing that is compatible with complementary metal–oxide–semiconductors (CMOS) has provided new opportunities for integrated ferroelectrics. To understand the mechanisms that control and induce switchable states in these materials, we use a variety of electron microscopy...
This talk will outline recent and ongoing efforts in the group focusing on data-driven design, computational study and experimental characterisation (performed via collaborative efforts) of melanins and melanin-inspired materials for biomedical devices or energy/information storage.
The consumption of electronics has increased dramatically in the past decades and so has the amount of electronic waste (e-waste). The pressure of the electronics industry contributes to the scarcity of certain chemical elements such that their recycling through urban mining is imperative. Beyond dealing with the important and urgent matter of extracting critical, precious and strategic...
This talk will present the latest research from the Nanoscale Energy and Interfacial Transport Lab (NEITLab) on advanced thermal management solutions for high-power electronics. The discussion will begin with a detailed examination of a two-phase evaporative cooling system that dissipates heat fluxes exceeding 560 W/cm² using water. This system offers a robust solution for addressing the...
The world first laptop, produced in 1981, features 12.7 cm screen and mass of 11.1 kg, comparing it with the latest apple technology with a 15 inch screen and weighed 1.51 kg. This is due to the appetite for the latest gadgets which increases electronic waste. The electronic waste increases the need for dumping space with developed countries using poor communities as for new dumping sites. The...

Cu doped CdO has been studied as thin film materials for solar cells and optoelectronic devices. In this study, low cost chemical bath technique is used to deposit Cu doped CdO on glass substrate. The structural properties of the thin film are investigated at different copper ion concentrations of 0.02M to 0.10M. XRD (X-ray diffraction) and SEM (scanning electron microscopy) showed that copper...
Wide bandgap (WBG) semiconductors have received significant attention for their potential as a next generation materials for high voltage power and RF electronics application. However, the high power densities and low thermal conductivity of some WBG materials presents a challenge for thermal management processes. The large intrinsic thermal resistance may cause the temperature induced...
This research investigates the upcycling of mango seed coat waste as natural fibre reinforcements in biodegradable polylactic acid (PLA)-based composite 3D printing filaments for structural applications in the energy sector. By integrating agricultural waste fibres into a PLA matrix, the study addresses the need for eco-friendly materials and innovative waste management strategies. The fibres...
