The porosity of the microspheres was investigated using mercury intrusion porosimetry (Micromeritics Autopore IV 9500). A 5 cc powder penetrometer (Micrometrics) with a 1 cc intrusion volume was used for all samples. An empty penetrometer test was also conducted as a blank before running the samples.
5 cc powder penetrometer
Manufactured by Micrometrics
The 5 cc powder penetrometer is a device used to measure the penetration depth of a powder sample under controlled conditions. It provides a quantitative assessment of the powder's compaction properties without making inferences about its intended use.

The surface area was determined via gas adsorption using the BET technique (Micrometrics Gemini 2360) where approximately 0.5 g of the microspheres were initially degassed under nitrogen at 110 o C for at least 2 h before performing multipoint BET analysis.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
