New methodology for the organocatalysed α-Amination reaction
… Herein we report the first application of this methodology to acetals, with the ultimate goal of applying the methodology to the asymmetric desymmetrisation of bis-acetals as a novel contribution to this growing field. Following extensive optimisation, acidic reaction conditions for the reaction …

New Methodology to Model Metal Chemistry at High Temperature
… reflect true electrochemical behavior. Herein, a new approach to modeling electrolytes is developed. By examining liquid solutions in a traditional chemical thermodynamic framework, and using this as a foundation for combining targeted experiments with calculated Gibbs energy data, deeper insights …

Two-Electrode Voltage Clamp (TEVC) Based Scanning Ion Conductance Microscopy: New Methodology and Validation
… Comparing with the single-electrode system, this new system can handle high current-capacity measurements and is inherently insensitive to noise which is the challenge of measuring small currents. This research will explore the ability to recover topographic images of non-conductive samples using …

THE ROBOTFALCON: A NEW METHODOLOGY TO STUDY PREY-PREDATOR INTERACTION AND AN INNOVATIVE BIRD DETERRENCE TOOL
Predation and predator–prey interactions are among the key processes shaping species traits and the functioning of ecosystems. Predators can influence prey through both lethal and non-lethal effects. The latter are less straightforward and therefore less explored than the former, yet they are …
