Non-equilibrium Dynamics of Nanoscale Soft Matter Deformation
Life is soft. From the fluid-like structure of lipid bilayers to the flexible folding of proteins, the realm of nanoscale soft matter is a complex and vibrant area of research. The lure of personalized medicine, advanced sensing technology, and understanding life at a fundamental level pushes …

Microfluidics enhanced synthesis of micellar nanostructures
… flow conditions. In equilibrium, micelles can transition from entangled to branched structures with increasing ionic strength and temperature. Under flow conditions, micellar structure transition can follow different trajectories. In the present work, the structural and rheological evolution of …

Magnetism, Structure and their Interactions
In my work, magnetic and structural transitions of three categories of compounds are investigated by density functional calculations under local spin density approximation (LSDA). The first compound is Rh2MnGe with full Heusler structure at ambient condition. However, the structure is unstable at …

The effects of spatial confinement and oxygen stoichiometry on complex metal oxides
Complex metal oxides, such as transition-metal oxides, appearing with exotic properties and optimal functionalities, present formidable challenges in condensed matter physics, while at the same time, immense opportunities in materials science and engineering. The signature of these materials is the …

Stability, transport and applications of polyaphrons in porous media
… that upon dilution polyaphrons may experience a structure transition, i.e. from bilayer structure to mixed monolayer structure. We examine the efficiency of our novel procedure on removing 1,2-dichlorobenzene (DCB) from a sand column. The results show that our procedure effectively prevents …

Dynamic Crystallization and Stability Engineering in Hybrid Organic-Inorganic Perovskites: Towards Water-Stable and Thermochromic Materials
… under basic conditions maintainedtheir structure for over one month in direct contact with water. In contrast, crystals synthesized under acidic condition decomposed within one day. This approach represents a new synthetic method for making ionic perovskite structures. In Chapter 3, we …

Protein-Protein Interactions in Cell Cycle Proteins: An <i>In silico</i> Investigation of Two Important Players
… Region (IDR) seems to undergo a disorder-to-structure transition upon binding to Clb2. Though numerous papers emphasize the importance of Cdc6’s LxF motif in its binding to Clb2, we revealed that a glutamate residue near the LxF motif appears to play a key role in Clb2 interactions with its …

Computations of Flow Structures and Heat Transfer in a Dimpled Channel at Low to Moderate Reynolds Number
… used to investigate the three-dimensional flow structure and understand its influence on the heat transfer in a channel with concave indentations on one wall. A dimple depth to channel height ratio of 0.4 and dimple depth to imprint diameter ratio of 0.2 is used in the calculations. The Reynolds …
