HDO Ice Detected toward an Isolated Low-mass Protostar with JWST

open access: yesThe Astrophysical Journal Letters
Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

open access: yesAdvanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Effect of Regolith–Ice Stratigraphy and Laser Weathering on Ultraviolet–Visible–Near-infrared Detection of Lunar Water Ice

open access: yesThe Planetary Science Journal
Investigating volatiles is critical for understanding their delivery to the Moon and for their potential as a resource for sustained lunar exploration. Water ice and potentially other volatiles are known to exist in and proximal to permanently shadowed ...

Phonon abundance-stiffness-lifetime transition from the mode of heavy water to its confinement and hydration

open access: yes, 2018
A combination of the temporally and spatially resolved phonon spectroscopy has enabled calibration of hydrogen bond transition from the vibration mode of heavy water to the core/shelled nanodroplet and the subnanosized ionic hydration shell in terms of ...

Hexagonal ice : Single crystalline hexagonal ice studied through surface-specific vibrational spectroscopy

open access: yes, 2017
In this thesis, we study the surface of water in its liquid and solid state. We investigate (i) an aqueous system where a model membrane interacts with amphiphilic dendrimers and (ii) single crystalline ice. We present a molecular scale description of both systems.

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Boron Nitride Nanomesh: A template for Nano-ice

open access: yes, 2009
Using variable temperature scanning tunneling microscopy and dI/dz barrier height spectroscopy, the structure of water on h-BN/Rh(111) nanomesh has been investigated. Below its desorption temperature, two distinct phases of water self-assemble within the

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

open access: yesAdvanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Observation of Ice-Like Two-Dimensional Flakes on Self-Assembled Protein Monolayer without Nanoconfinement under Ambient Conditions

open access: yesNano-Micro Letters
Highlights The two-dimensional (2D) ice-like water layers are formed on the self-assembled monolayers (SAMs), which support the physisorption of Cytochrome C (Cyt C) protein layer under ambient conditions, without the need for nanoconfinement.
