Abstract:
Hollow mesoporous silica nanoparticles (HMSNs) with different dispersities, mesoporous structures and particle sizes have been systematically synthesized by simply changing the octadecyltrimethoxysilane (C18TMS, mesopore-forming agent) percentage of the total silica sources over a wide range. The effects of the C18TMS percentage on the dispersity, mesoporous structure and particle size of HMSNs have been discussed in detail based on elaborate structure characterization. In addition, the volume of the core-etching agent and etching time have been adjusted carefully to further modulate the mesoporous structure of HMSNs. Encouragingly, the obtained HMSNs show excellent performance in removing organic pollutants with short equilibrium adsorption time, high adsorption capacity and outstanding recyclability. It is believed that these prepared HMSNs with different dispersities, mesoporous structures and particle sizes possess the potential to be used in many fields.

Microsoft Excel: Plotting Mean, SD, and SE
First, calculate the mean, SD, and SE of your data. The mean is obtained using the formula `=AVERAGE(range)`, while SD can be calculated with `=STDEV.P(range)` for a population or `=STDEV.S(range)` for a sample. SE is calculated as `=SD/SQRT(n)`, where `n` is the sample size.
To plot these values, use a bar...
