SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

X-ray free-electron lasers

Nature Photonics, 2010
With intensities 108–1010 times greater than other laboratory sources, X-ray free-electron lasers are currently opening up new frontiers across many areas of science. In this Review we describe how these unconventional lasers work, discuss the range of new sources being developed worldwide, and consider how such X-ray sources may develop over the ...

X-ray Free-electron Lasers

AIP Conference Proceedings, 2009
We review the present status and properties of X‐ray free‐electron lasers in operation or under construction in the nanometer and sub‐nanometer wavelength range, and the novel possibilities they offer for the study of atomic and molecular processes. We also discuss recent developments in relativistic electron beam physics that give us the possibility ...

Molecular Imaging Using X-Ray Free-Electron Lasers

Annual Review of Physical Chemistry, 2013
The opening of hard X-ray free-electron laser facilities, such as the Linac Coherent Light Source (LCLS) at SLAC National Accelerator Laboratory in the United States, has ushered in a new era in structural determination. With X-ray pulse durations down to 10 fs or shorter, and up to 1013transversely coherent photons per pulse in a narrow spectral ...

Compact X-Ray Free-Electron Laser

Short Wavelength Coherent Radiation: Generation and Applications, 1988
We present a design concept and simulation of the performance of a compact x-ray, free electron laser driven by ultra-high gradient rf-linacs. The accelerator design is based on recent advances in high gradient technology by a LLNL/SLAC/LBL collaboration† and on the development of bright, high current electron sources by BNL and LANL.

Virus Structures by X-Ray Free-Electron Lasers

Annual Review of Virology, 2019
Until recently X-ray crystallography has been the standard technique for virus structure determinations. Available X-ray sources have continuously improved over the decades, leading to the realization of X-ray free-electron lasers (XFELs). They provide high-intensity femtosecond X-ray pulses, which allow for new kinds of experiments by making use of ...

Focusing mirror for x-ray free-electron lasers

Review of Scientific Instruments, 2008
We present the design, fabrication, and evaluation of a large total-reflection mirror for focusing x-ray free-electron laser beams to nanometer dimensions. We used an elliptical focusing mirror made of silicon that was 400mm long and had a focal length of 550mm.

x-Ray Free-Electron Lasers

2014
Free-electron lasers (FELs) operating in the soft and hard x-ray wavelength range deliver unprecedented peak and average brilliance, opening new scientific opportunities in many disciplines. A striking advance compared to third-generation synchrotron-based light sources is the duration of the photon pulse: a few to some hundred femtoseconds with peak ...
