- Description:
- Thermoelectric materials have attracted widespread attention in recent decades because of their ability to directly convert thermal energy into electrical energy. Given that waste heat is the primary source of lost energy in the world, the implications of developing better thermoelectric materials are both immediate and far-reaching. Admittedly, large progress...

- Description:
- Dual-phase (DP) steels have been widely applied in automobile industry, and are famous for continuous yielding in their corresponding stress-strain curves. The appearance of yield-point phenomena, or discontinuous yielding, is considered undesirable for DP steels. Herein, we take advantage of the undesirable appearance of yield-point phenomena in DP steels as...

- Description:
- Liquid 3He is the paradigm system for studying exotic quantum mechanical phenomena observed in nature. The normal state of 3He is a strongly-correlated Fermi liquid with strong ferromagnetic spin fluctuations. However, as we cool 3He down to T = 0K, we find something fascinating and unexpected. This exotic fluid remains...

- Description:
- In the absence of any significant federal policy to mitigate climate change, many (though not all) U.S. states have stepped in to fill the void. But the policies these states have adopted vary considerably in their quality. For example, California’s economy-wide greenhouse gas policy was significantly stronger than Massachusetts’, which...

- Description:
- Recently, a myriad of applications take advantage of deep learning methods to solve regression/classification problems. Although deep neural networks have shown powerful learning capability, many deep learning applications suffer from the extremely time-consuming training of the neural networks. In order to reduce the training time, researchers usually consider parallel training...

- Description:
- This dissertation examines the effects of phase transfers with thiol ligands on the optical properties of quantum dots (QDs) in water by investigating two systems: i) dihydrolipoic acid (DHLA)-capped PbS QDs and ii) thiolated DNA-capped core/shell CdSe/CdS QDs. QDs are bright, monodisperse, and tunable hydrophobic nanoparticles with high photoluminescence (PL)...
