Digging out structural changes of surrounded proteins
Modeling when micelles surrounding membrane proteins can be ignored as well as when — and how — they must be dealt with during time-resolved X-ray solution scattering.
Co-published by AIP Publishing and ACA, a peer-reviewed, open access journal publishing research on
Structural Dynamics aims at capitalizing on the recent developments in experimental and theoretical methods and techniques that allow a visualization of the electronic and geometric structural changes in “real-time” of chemical, biological and condensed matter systems. The community of scientists and engineers working on structural dynamics in such diverse systems often use similar instrumentation
and methods. The journal welcomes articles dealing with fundamental problems of electronic and structural dynamics that are tackled by new methods such as:
- Time-resolved X-ray and electron diffraction and scattering
- Coherent diffractive imaging
- Time-resolved X-ray spectroscopies (absorption, emission, resonant inelastic scattering, etc.)
- Time-resolved Electron Energy Loss Spectroscopy (EELS) and electron microscopy
- Time-resolved photoelectron spectroscopies (UPS, XPS, ARPES, etc.)
- Multidimensional spectroscopies in the infrared, the visible and the ultraviolet
- Nonlinear spectroscopies in the VUV, the soft and the hard X-ray domains
- Theory and Computational methods and algorithms for the analysis and description of structural dynamics and their associated experimental signals. These new methods are enabled by new instrumentation such as:
- X-ray free electron lasers, which provide flux, coherence and time resolution
- New sources of ultrashort electron pulses
New sources of ultrashort Vacuum Ultraviolet (VUV) to hard X-ray pulses, such as high harmonic generation (HHG) sources or plasma-based sources
- New sources of ultrashort infrared and terahertz (THz) radiation
- New detectors for X-rays and electrons
- New sample handling and delivery schemes
- New computational capabilities
The journal welcomes articles that deal either with scientific or technical aspects of these new methods and instruments. Experimental papers are expected to be brought into relation with theory, and theoretical papers should be connected to present or future experiments. The journal accepts Short Communications, Topical Reviews and Regular Articles in the following subjects:
- Experimental Methodologies
- Theory and Modelling
- Surfaces and Interfaces
- Materials
- Liquids and Solutions
- Biological Systems
