Dynamic Light Scattering based microrheology of End-functionalised triblock copolymer solutions [PDF]
arXiv, 2022 'Soft' patchy surfactant micelles have become an additional building tool in self-assembling systems. The triblock copolymer, Pluronic F108, forms spherical micelles in aqueous solutions upon heating leading to a simple phase diagram with a micellar crystalline solid at higher temperatures and concentrations.

A cell-permeable biscyclooctyne as a novel probe for the identification of protein sulfenic acids [PDF]
, 2016 Reactive oxygen species act as important second messengers in cell signaling and homeostasis through the oxidation of protein thiols. However, the dynamic nature of protein oxidation and the lack of sensitivity of existing molecular probes have hindered ...

Structure, elastic and dynamical properties of KN$_3$ and RbN$_3$: A van der Waals density functional study [PDF]
Solid state sciences, vol 23, pp, 17-25 (2013), 2013 We report a detailed first principles study on the structural, elastic, vibrational and thermodynamic properties of layered structure energetic alkali metal azides KN$_3$ and RbN$_3$. All the calculations were carried out by means of plane wave pseudopotential method with and without including van der Waals interactions.

Phase stability and lattice dynamics of ammonium azide under hydrostatic compression [PDF]
Physical Chemistry Chemical Physics, 17, 29210-29225, (2015), 2015 We have investigated the effect of hydrostatic pressure and temperature on phase stability of hydro-nitrogen solids using dispersion corrected Density Functional Theory calculations. From our total energy calculations, Ammonium Azide (AA) is found to be the thermodynamic ground state of N$_4$H$_4$ compounds in preference to Trans-Tetrazene (TTZ), Hydro-

Site-Selective Dynamics of Azidolysozyme [PDF]
, 2021 The spectroscopic response of and structural dynamics around all azido-modified alanine residues (AlaN$_3$) in Lysozyme is characterized. It is found that AlaN$_3$ is a positionally sensitive probe for the local dynamics, covering a frequency range of $\sim 15$ cm$^{-1}$ for the center frequency of the line shape.
