Evidence for Multiple Pathways to Deuterium Enhancements in Protoplanetary Disks

open access: yes, 2012
The distributions of deuterated molecules in protoplanetary disks are expected to depend on the molecular formation pathways. We use observations of spatially resolved DCN emission from the disk around TW Hya, acquired during ALMA Science verification ...

Unravelling the Atomic Structure of a Metal‐Covalent Organic Framework Assembled from Ruthenium Metalloligands

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Xolography for Rapid Volumetric Production of Objects from the Nanoscopic to Macroscopic Length Scales

open access: yesAdvanced Materials, EarlyView.
This article explores the development of materials with multi‐scale control at the nanoscale (<100 nm), micrometer‐scale (80 µm), and macro‐scale (multi‐component geometries). This is achieved by applying polymerization‐induced microphase separation (PIMS) process via volumetric 3D printing (Xolography), expanding the design space for functional ...
