Aryl ethynyl phthalic anhydrides and polymers with terminal or pendant amines prepared with aryl ethynyl phthalic anhydrides
(United States Patent and Trademark Office, 1996-02-20)Arylethynyl phthalic anhydrides have been synthesized and shown to have particular application as endcappers or pendant groups in high performance/high temperature thermosets which include amine terminal or amine pendant groups. -
Assembly of Bio-Nanoparticles for Double Controlled Drug Release
(PLOS, 2013-09-06)A critical limiting factor of chemotherapy is the unacceptably high toxicity. The use of nanoparticle based drug carriers has significantly reduced the side effects and facilitated the delivery of drugs. Source of the ... -
An atomic force microscope tip as a light source
(AIP Publishing, 2005-12-01)We present a simple method for causing the end of a silicon nitride atomic force microscope (AFM) tip to emit light, and we use this emitted light to perform scanning near-field optical microscopy. Illumination of a silicon ... -
Atomic resolution tracking of nerve-agent simulant decomposition and host metal-organic framework response in real space
(2021-01-04)Gas capture and sequestration are valuable properties of metal-organic frameworks (MOFs) driving tremendous interest in their use as filtration materials for chemical warfare agents. Recently, the Zr-based MOF UiO-67 was ... -
Atomic-Level Structural Dynamics of Polyoxoniobates during DMMP Decomposition
