A Ship‐in‐a‐Bottle Strategy: Crosslinking Amines and Epoxides inside MOF Pores for Enhanced CO2 Capture Performance

Advanced Materials, EarlyView.
A “ship‐in‐a‐bottle” strategy is used to grow oligomers inside of a MOF by crosslinking alkylamines with epoxides within the pores of Cr‐BDC. When tested in postcombustion carbon capture applications, the composites show excellent performance with high CO2 adsorption capacity, exceptional CO2/N2 selectivity, and enhanced stability over 100 adsorption ...

Chemoselective Characterization of New Extracellular Matrix Deposition in Bioengineered Tumor Tissues

Advanced Materials, EarlyView.
Understanding the bi‐directional crosstalk between cells and their surrounding extracellular matrix (ECM) is critical for tissue engineering. This study presents a chemoselective strategy for proteomic profiling of newly deposited ECM from resident cells.

Light-Dependent Changes in the Spatial Localization of Metabolites in Solenostemon scutellarioides (Coleus Henna) Visualized by Matrix-Free Atmospheric Pressure Electrospray Laser Desorption Ionization Mass Spectrometry Imaging

Frontiers in Plant Science, 2018
The visualization of foliage color in plants provides immediate insight into some of the compounds that exist in the leaf. However, many non-colored compounds are also present; their cellular distributions are not readily identifiable optically.

Disruption of Sulfur Metabolism and Redox Homeostasis in Staphylococcus aureus Using Mechanically Robust Antibiofilm Ti‐Bi Alloys

Advanced Materials Interfaces, EarlyView.
Titanium (Ti) and bismuth (Bi) are selected as alloying elements for the preparation of the Ti‐Bi binary alloy system. Biofilm formation is found to be inhibited by bismuth through the disruption of sulfur metabolism and redox homeostasis, as well as through the direct downregulation of biofilm‐associated proteins.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
