Towards an Optimal Sample Delivery Method for Serial Crystallography at XFEL

Crystals, 2020
The advent of the X-ray free electron laser (XFEL) in the last decade created the discipline of serial crystallography but also the challenge of how crystal samples are delivered to X-ray.

Hexagonal dielectric resonators and microcrystal lasers [PDF]

, 2002
We study long-lived resonances (lowest-loss modes) in hexagonally shaped dielectric resonators in order to gain insight into the physics of a class of microcrystal lasers.

Facile regulation of cuprous oxide microcrystal morphology and planes for visible light photocatalytic degradation

Micro & Nano Letters, 2022
Cuprous oxide (Cu2O) microcrystal is an excellent material for absorbing visible light and photo‐catalyzing various water pollutants. The photocatalytic performance of Cu2O crystal mainly depends on its morphology and exposure surface.

Microcrystal manipulation with laser tweezers [PDF]

Acta Crystallographica Section D Biological Crystallography, 2013
X-ray crystallography is the method of choice to deduce atomic resolution structural information from macromolecules. In recent years, significant investments in structural genomics initiatives have been undertaken to automate all steps in X-ray crystallography from protein expression to structure solution.
