Multiple Twinning in Nacre and Aragonite
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed

Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing
In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...

Ray Tracing and Physical Optics for Geodesic and GRIN Lens Antennas
This thesis investigates the ray tracing (RT) and physical optics (PO) method for geodesic and gradient-index (GRIN) lens antennas in both far and near fields at millimeter-wave frequencies (from around 30 GHz up to 110 GHz). In particular, parallel-plate-waveguide (PPW) based GRIN lenses and geodesic H-plane horns are studied to realize high-gain ...
