Analysis of lava flow impacts for use in risk assessments
Published 2023“…This suggests that structure typology is important, with concrete and cylindrical structures showing resistance to thin flows. I show that damage extended beyond the flow channel in breakout flows and overflows, and extended up 600 m away from the lava flow margin due to the fire spread at Kīlauea, extending potential impact beyond the modelled channel footprint. …”

Mechanics in dehydration-induced leaf morphing behaviors
Published 2024“…As the leaf naturally detaches and dries, the leaf lamina shrinks more than the stiff midrib, resulting in in-plane strain mismatch between the mesophyll tissues and the midrib. For thin-sheet materials like plant leaves, uniform uniaxial stretching of the sheet leads to wrinkling, a phenomenon that has been extensively studied analytically and numerically. …”

Exciton Dynamics and Anisotropy in 2D Metal Organochalcogenolate Semiconductors
Published 2024“…First, we present the synthesis, structural and optical properties of 2D AgEPh (E = S, Se, Te) single crystals, colloidal nanocrystals, and thin films. Importantly, the growth of millimeter-sized single crystalline 2D AgEPh (E = S, Se, Te) enables their crystal structure determination via single crystal X-ray diffraction: AgSPh in P2₁, AgSePh in P2₁/c, and AgTePh in P2₁/c. …”

Suppressed deep traps and bandgap fluctuations in Cu2CdSnS4 solar cells with ≈8% efficiency
Published 2021“…Cu2ZnSn(S,Se)4-based solar cells have shown promising power conversion efficiencies in recent years, but their performance remains inferior compared to other thin-film solar cells. Moreover, the fundamental material characteristics that contribute to this inferior performance are unclear. …”

Electrochemical DNA biosensor based on nanoporous alumina membrane
Published 2014“…In the following chapter, we demonstrated a novel and integrated membrane sensing platform relying on free-standing anodic aluminum oxide (AAO) for the detection of oligonucleotide sequence using electrochemical impedance spectroscopy. Here, ultra-thin platinum layers were deposited as porous electrodes on both sides of AAO membrane and used as working and counter electrodes, respectively, for the impedance and differential pulse voltammetry measurements. …”

Analysis and exploitation of dispersive waves for source localization on solids
Published 2018“…The challenge of this research lies in the fact that transverse propagating waves on a thin elastic plate are dispersive in nature. As opposed to wave propagation in a non-dispersive medium such as air, a dispersive medium results in a wave propagation speed that is frequency dependent. …”

Uncovering vein patterns from color skin images for personal identification in forensic investigation
Published 2013“…All the current vein recognition systems developed by companies and research laboratories rely on near infrared (NIR) imaging devices to capture high quality vein patterns from hand and wrist, where skin is relatively thin, for commercial applications. Up until now, no one studies vein patterns for forensic identification because no method has been developed to visualize vein patterns hidden in color images. …”
