Watching a signaling protein function: What has been learned over four decades of time-resolved studies of photoactive yellow protein [PDF]

Structural Dynamics
Photoactive yellow protein (PYP) is a signaling protein whose internal p-coumaric acid chromophore undergoes reversible, light-induced trans-to-cis isomerization, which triggers a sequence of structural changes that ultimately lead to a signaling state ...

Time-resolved studies of individual molecular rotors

Journal of Physics: Condensed Matter, 2010
Thioether molecular rotors show great promise as nanoscale models for exploring the fundamental limits of thermally and electrically driven molecular rotation. By using time-resolved measurements which increase the time resolution of the scanning tunneling microscope we were able to record the dynamics of individual thioether molecular rotors as a ...

Strontium Substituted Tricalcium Phosphate Bone Cement: Short and Long‐Term Time‐Resolved Studies and In Vitro Properties

Advanced Materials Interfaces, 2022
Due to a significant influence of strontium (Sr) on bone regeneration, Sr substituted β‐tricalcium phosphate (Sr‐TCP) cement is prepared and investigated by short‐ and long‐term time‐resolved techniques. For short‐term investigations, energy‐dispersive X‐

3D-printed sheet jet for stable megahertz liquid sample delivery at X-ray free-electron lasers

IUCrJ, 2023
X-ray free-electron lasers (XFELs) can probe chemical and biological reactions as they unfold with unprecedented spatial and temporal resolution. A principal challenge in this pursuit involves the delivery of samples to the X-ray interaction point in ...

Nanosecond X-ray photon correlation spectroscopy using pulse time structure of a storage-ring source

IUCrJ, 2021
X-ray photon correlation spectroscopy (XPCS) is a routine technique to study slow dynamics in complex systems at storage-ring sources. Achieving nanosecond time resolution with the conventional XPCS technique is, however, still an experimentally ...

Time-resolved photoluminescence study of SiAg [PDF]

Physica B: Condensed Matter, 2001
Abstract Photoluminescence band at 780 meV , previously assigned to silver-related centers in Si on basis of indirect arguments, is investigated in detail. For that purpose specially prepared samples doped with isotopically enriched silver are used.

Time-resolved study of the photodissociation of Au2O− [PDF]

Chemical Physics Letters, 2007
Photodissociation of the Au2Oanion following absorption of a 3.1 eV photon is studied using time-resolved photoelectron spectro- scopy. A new spectral feature appearing after 1 ps indicates the existence of a long-lived excited state with a geometry different from that of the ground state.
