Liquid metal solvents for high entropy and atomically configured systems. Significant challenges remain in developing high entropy alloys, which are future disruptors in metallurgy, ranging from configurational entropy to atomic ordering.

Significant challenges remain in developing high entropy alloys, which are future disruptors in metallurgy, ranging from configurational entropy to atomic ordering. To address such challenges, we will explore liquid metal solvents for synthesising high entropy and atomically configured systems from the combination of reactive and high melting point elements stabilised in metallic solvents. Molecular imprinting, mechanical and electrochemical triggers will control interfacial atomic organisation and precipitation. The growth mechanisms, both at the interface and in the bulk, will be explored by high energy probing techniques and computational simulations. We will offer new metallurgical paradigms for future catalysis and sensing concepts.Read moreRead less
Accessing Liquid Noble Metals for Low Temperature Chemical Reactions. We will explore noble metals in liquid form at low temperatures. We will show that while noble metals melting points are above 1000°C, a gallium matrix will allow their existence in liquid form at low temperatures (<75°C). A variety of noble metal gallium alloy combinations will be investigated for their catalytic activities which are expected to show very high kinetics. We will study both bulk and low dimensional analogues to ....Accessing Liquid Noble Metals for Low Temperature Chemical Reactions. We will explore noble metals in liquid form at low temperatures.

A variety of noble metal gallium alloy combinations will be investigated for their catalytic activities which are expected to show very high kinetics. We will study both bulk and low dimensional analogues to understand the atomic dispersion of noble metals on interface and in the core of the alloys, for discoveries regarding the liquid state catalytic properties of the mixes. Subsequently, model chemical reactions will reveal the enhancement of the kinetics and what the project can offer to industrial innovations. Read moreRead less
