An initial tranche of results from day-to-day use of a robotic system for setting up 100 nl-scale vapour-diffusion sitting-drop protein crystallizations has been surveyed. The database of over 50 unrelated samples represents a snapshot of projects currently at the stage of crystallization trials in Oxford research groups and as such encompasses a broad range of proteins. The results indica...... hiện toàn bộ
A procedure for setting up high-throughput nanolitre crystallization experiments. I. Protocol design and validationJournal of Applied Crystallography - Tập 36 Số 2 - Trang 308-314 - 2003

A protocol for setting up nanolitre sitting-drop vapour-diffusion experiments is reported. The procedure uses standard crystallization screening kits and 96-well crystallization plates. Reservoir solutions are transferred from 96-deep-well blocks to crystallization plates in a single step with a Robbins-Hydra pipettor. Nanolitre droplets of protein as well as reservoir solution are dispens...... hiện toàn bộ
refnx: neutron and X-ray reflectometry analysis in PythonJournal of Applied Crystallography - Tập 52 Số 1 - Trang 193-200 - 2019
Andrew Nelson, Stuart W. Prescott
refnxis a model-based neutron and X-ray reflectometry data analysis package written in Python. It is cross platform and has been tested on Linux, macOS and Windows. Its graphical user interface is browser based, through aJupyternotebook. Model construction is modular, being composed from a series of components that each describe a subse...... hiện toàn bộ
Structure evolution of aluminosilicate sol and its structure-directing effect on the synthesis of NaY zeoliteJournal of Applied Crystallography - Tập 50 Số 1 - Trang 231-239 - 2017
Xiao‐Meng Zhao, Rugeng Liu, Heng Zhang, Yunshan Shang, Yu Song, Chao Liu, Tao Wang, Yanjun Gong, Zhihong Li
Understanding the growth behaviour of an aluminosilicate sol during ageing is necessary for the design of the sol and the synthesis of NaY zeolite. Herein, aluminosilicate sols with three different SiO2/Al2O3 ratios were prepared and aged for varying times at 293 K. The sol was then introduced as a structure-directing agent in ...... hiện toàn bộ
An operando spatially resolved study of alkaline battery discharge using a novel hyperspectral detector and X-ray tomographyJournal of Applied Crystallography - Tập 53 Số 6 - Trang 1434-1443 - 2020
Thomas Connolley, Oxana V. Magdysyuk, Š. Michalik, Phoebe K. Allan, Manuela Klaus, Paul H. Kamm, Francisco García‐Moreno, Jennifer Nelson, Matthew C. Veale, Matthew D. Wilson
An experimental technique is described for the collection of time-resolved X-ray diffraction information from a complete commercial battery cell during discharging or charging cycles. The technique uses an 80 × 80 pixel 2D energy-discriminating detector in a pinhole camera geometry which can be used with a polychromatic X-ray source. The concept was proved in a synchrotron X-ray study of c...... hiện toàn bộ
Sự xấp xỉ của các đỉnh tia X đối xứng bằng phân phối kiểu VII của Pearson Dịch bởi AI Journal of Applied Crystallography - Tập 10 Số 1 - Trang 66-68 - 1977
M. M. Hall, V. G. Veeraraghavan, Herman Rubin, P. G. Winchell
Các đỉnh tia X đối xứng có thể được xấp xỉ hình dạng bằng các phân phối kiểu VII của Pearson: y(x) = y_0[1 + (x - \bar x)^{2}/ma^2]^{-m}. Phân phối này là Cauchy khi m = 1, Lorentzian sửa đổi khi m = 2, và Gaussian khi m = ∞. Một số tính chất của phân phối và một số ứng dụng minh họa được trình bày.
