Mass spectrum of gapped, non-confining theories with multi-scale dynamics [PDF]

Journal of High Energy Physics, 2019
We study the mass spectrum of spin-0 and spin-2 composite states in a one-parameter family of three-dimensional field theories by making use of their dual descriptions in terms of supergravity.

Dual Minimization of Spectrum Overlap for High-Sensitivity, High-Temperature Sensing [PDF]

Sensors
Minimizing the spectrum overlaps of energy transfer (ET) is necessary but not sufficient for achieving high-sensitivity film thermosensing. Herein we have designed two blue emitters of DBA-BPAc and Z-DBABH exhibiting blue and bluish-green emissions ...

Study of the interaction of sorbed silver, gold and copper ions with functional groups on hydrolyzed fibroin using Charmm22 force field calculations [PDF]

Chemical Review and Letters, 2022
We studied the sorption of silver, gold, and copper ions into powdered hydrolyzed fibroin derived from silk fibroin fibers. Metal ions sorbed into hydrolyzed fibroin have been found to interact with active functional groups over time. It was hypothesized
