Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

NanoMAX: A hard x-ray nanoprobe beamline at MAX IV

, 2013
We describe the design of the NanoMAX beamline to be built among the first phase beamlines of the MAX IV facility in Lund, Sweden. NanoMAX will be a hard X-ray imaging beamline providing down to 10 nm in direct spatial resolution, enabling investigations

Research on improving measurement stability of mine-used X-ray nuclear scale

Gong-kuang zidonghua, 2018
In order to improve measurement stability of mine-used X-ray nuclear scale, specific methods were given from two aspects of explosion-proof X-ray source and measurement zero point.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

TeV gamma-ray emission from accreting binary pulsars [PDF]

, 1990
The high-mass X-ray binary SMC X-1 has been observed during the interval 1986-1989 at a threshold γ-ray energy of 0.4 TeV using the University of Durham Mark III air Cerenkov telescope at Narrabri.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

View synthesis for depth from motion 3D x-ray imaging.

, 2009
The depth from motion or kinetic depth X-ray imaging (KDEX) technique is designed to enhance the luggage screening at airport checkpoints. The technique requires multiple views of the luggage to be obtained from an arrangement of linear X-ray detector ...

Characterisation of very thin epitaxial layers by high resolution x-ray diffraction [PDF]

, 1989
X-rays can be used as a sensitive, non-destructive probe for the characterisation of semiconductors. The energy and wavelength of X-rays is such that structural information down to the Ảngstrom level can be yielded with a depth penetration of several ...
