Abstract
Synthetic sophisticated nanostructures represent a fundamental building block for the development of nanotechnology. The fabrication of nanoparticles complex in structure and material composition is key to build nanomachines that can operate as man-made nanoscale motors, which autonomously convert external energy into motion. To achieve this, asymmetric nanoparticles were fabricated combining a physical vapor deposition technique known as NanoGLAD and wet chemical synthesis. This thesis primarily concerns three complex colloidal systems that have been developed: i)Hollow nanocup inclusion complexes that have a single Au nanoparticle in their pocket. The Au particle can be released with an external trigger. ii)The smallest self-propelling nanocolloids that have been made to date, which give rise to a local concentration gradient that causes enhanced diffusion of the particles. iii)Enzyme-powered pumps that have been assembled using bacteriophages as biological nanoscaffolds. This construct also can be used for enzyme recovery after heterogeneous catalysis.

Beyond Bounded Rationality: Reverse-Engineering and Enhancing Human Intelligence

Abstract
Bad decisions can have devastating consequences: There is a vast body of literature claiming that human judgment and decision-making are riddled with numerous systematic violations of the rules of logic, probability theory, and expected utility theory. The discovery of these cognitive biases in the 1970s (Tversky & Kahneman, 1974) made people question the concept of Homo sapiens as the rational animal, profoundly shaking the foundations of economics and rational models in the cognitive, neural, and social sciences. Four decades later, these disciplines still lack a rigorous theoretical foundation for explaining and remedying people’s cognitive biases. To solve this problem, my dissertation offers a mathematically precise theory of bounded rationality and demonstrates how it can be leveraged to elucidate the cognitive mechanisms of judgment and decision-making (Part 1) and to help people make better decisions (Part 2).
