The experimental pressure dependent Raman spectra of triamino-trinitrobenzene (TATB) are determined up to 24.5 GPa, and compared with those obtained using density functional theory (DFT) up to 27 GPa. The density functional theory calculations includ

While it is well established that the dominant degradation mechanism for the chemical warfare agent, sarin, is hydrolysis via an SN2 mechanism in aqueous environments, the same cannot be said when hydrophilic or hydrophobic surfaces are present. Util

The luminescent organosilicon copolymers poly(silafluorenyldiethynylspirobifluorene) and poly(tetrasilolediethynylspirobifluorene) have been covalently linked to a silica gel thin layer chromatography (TLC) support through the use of a trimethoxysily

The time scale and/or products of photoinduced decomposition of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) were investigated at ambient pressure and compared with products formed at 8 GPa. Ultrafast time-resolved infrared and steady-state Fourier tr

The reaction of sodium sulfide with chloroauric acid has been surrounded by a controversy over the structure of the resulting product. The original report proposed a Au2S/Au core/shell structure based on strong near-IR resonance and limited transmiss

Aqueous poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO109-PPO41-PEO109) copolymers are nonionic surfactants that self-organize to form aggregate structures with increasing temperature or concentration. We have studied two concen

Energy transfer dynamics in Mn 2+ -doped ZnSe nanoparticles have been studied by monitoring the photoluminescence using time-integrated and time-resolved spectroscopic techniques. Upon Mn 2+ doping, static photoluminescence (PL) spectra show that the

The correlation between the structure and shift of the extended surface plasma band in gold nanoparticle aggregates has been studied using small angle X-ray scattering (SAXS) and ultrasmall angle X-ray scattering (USAXS) techniques. The reduction of

Fluorescence spectroscopy is used to probe local environments within regions of different polarity and hydrophobicity in aqueous aggregates of PEO(109)-PPO(41)-PEO(109) triblock copolymers. These copolymer aggregates have well characterized microphas

A unique gold nanoparticle aggregate (GNA) system has been shown to be an excellent substrate for surface-enhanced Raman scattering (SERS) applications. Rhodamine 6G (R6G), a common molecule used for testing SERS activity on silver, but generally dif
