A field emission-scanning electron microscope (FE-SEM: S-4800, Hitachi High-Technologies, Tokyo, Japan) was utilized to confirm the sizes and surface conditions of α-TCP and α-Ph granules. Pore distribution and interparticle sizes of both granules before implantation were evaluated by the mercury intrusion technique using an Auto Pore IV 9510 (Micro-metrics, Norcross, GA, USA). The crystal phase of α-TCP was identified using an XRD system (XRD-6100, Shimadzu, Kyoto, Japan) and database from the International Center for Diffraction Data (α-TCP: 9-0348). X-ray photoelectron spectroscopy (XPS; PHI X-tool, ULVAC-PHI, Kanagawa, Japan) was used to confirm the attachment of heparin and SMP on the surface of the α-TCP.
Auto pore 4 9510
Manufactured by Micrometrics
Sourced in United States
The Auto Pore IV 9510 is a mercury intrusion porosimeter that measures the pore size distribution and porosity of materials. It operates by applying incremental pressure to a sample, causing mercury to intrude into the pores. The volume of mercury intruded is measured and used to calculate the pore size distribution and porosity of the sample.

The MIP analyses
were carried out in the Key Laboratory of Coalbed
Methane Resources and Reservoir Formation Process of the Ministry
of Education, China University of Mining and Technology. Samples with
sizes of 2–3 cm were vacuum-dried at a temperature of 110 °C
for 4 h and then placed in an AutoPore IV 9510, Micrometrics Instrument,
which could automatically control the experiments via a software that
was embedded in the instrument. After evacuation, the samples were
pressurized from 3.52 kPa to 414 MPa and the mercury contact angle
and surface tension during intrusion were set to 130° and 0.48
N/m, respectively. Due to the compressibility of coal pores at high
pressures, especially low mesopores at pressures above 20 MPa, the
results from mercury intrusion were corrected for coal compressibility.
The experimental procedure and data calculation followed the standard
method (ISO 15901-1:2005).

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.
