20230327-XPCS experimental data set

The dataset consists of two parts: XPCS and DLS experimental data. The XPCS experimental data was collected on SSRF 10U USAXS beam lines in March 2023, and the experimental parameters are as follows: The X-ray energy is 10 KeV; The distance between the sample and detector is 27.6 meters; The detector is EIGER X 4M, with a single pixel size of 75 microns; The experimental sample was a colloidal glycerol suspension. The water in the original solution (McLean, M814153) was replaced with glycerol using a rotary evaporator, resulting in a volume fraction of 1%. By using partially coherent X-ray, speckle patterns were collected at different exposure periods. The correlation function of the sample at different exposure periods and q values can be obtained through autocorrelation function. Data file name explanation: SiO2_ 500_ N1000_ 100ms_ GL_ ICT1_ 4165 is a colloid (SiO2)_ Particle size in nm_ Number of frames collected (N+number)_ Exposure period_ Medium (glycerol)_ Pinhole (100 microns)_ Data sequence number. The DLS experimental data was collected using the SSRF ancillary laboratories in July 2023 using the DLS device. The experimental parameters are as follows: Laser wavelength: 633 nm; Scattering angle: 90 °; Experimental temperature: 23.7 ℃; Dilute the original solution with pure water to different concentrations, and then place it in a quartz colorimetric dish for detection. The scattered signal is received by PMT and correlated with the correlation instrument (ALV-7004/USB-FAST) to obtain the results. We collected correlation signals at different concentrations and analyzed the impact of multiple scattering of colloids on particle size. Data file name explanation: SiO2_ 500_ X10_ 10sX10_ 2 is colloid (SiO2)_ Particle size in nm_ Dilution ratio (concentration of 1%/10)_ Collection cycle X times_ Data sequence number.
