Abstract

We have produced superstable compound liquid microjets with a 3D-printed coaxial flow-focusing injector. The aqueous jet core is surrounded by a shell, a few hundred nanometres in thickness, of a low-concentration aqueous solution of a low-molecular-weight polymer. Due to the stabilizing effect of the polymeric shell, the minimum liquid flow rate leading to stable flow-focusing is decreased by one order of magnitude, resulting in much thinner and longer jets. Possible applications of this technique for serial femtosecond X-ray crystallography are discussed.

被聚合外壳包围的微米射流的超稳定性。

我们已经用3d打印的同轴流聚焦喷射器生产了超稳定的复合液体微射流。水射流核心被一层几百纳米厚的壳层包围，壳层是低分子量聚合物的低浓度水溶液。由于聚合物外壳的稳定作用，导致稳定流动聚焦的最小液体流量降低了一个数量级，导致射流更薄更长。讨论了该技术在连续飞秒x射线晶体学中的应用。

期刊介绍： Many research topics in condensed matter research, materials science and the life sciences make use of crystallographic methods to study crystalline and non-crystalline matter with neutrons, X-rays and electrons. Articles published in the Journal of Applied Crystallography focus on these methods and their use in identifying structural and diffusion-controlled phase transformations, structure-property relationships, structural changes of defects, interfaces and surfaces, etc. Developments of instrumentation and crystallographic apparatus, theory and interpretation, numerical analysis and other related subjects are also covered. The journal is the primary place where crystallographic computer program information is published.
