Reflections were integrated and processed using iMOSFLM29 . Data were scaled and merged using SCALA30 (link). Structures were solved by the method of molecular replacement as implemented in program MOLREP12 (link) using the 2.4 Å structure of azurin C112D (PDBID: 1AG0) as a search model. The MOLREP output was then used for model building with ARP/wARP31 (link), with a single coordinate randomization included to alleviate any possible model bias. Maximum likelihood restrained refinement was carried out using program REFMAC512 (link).
Crystal Growth
This process involves the nucleation and growth of crystals, which can be influenced by factors such as temperature, pressure, and the presence of impurities.
Crystal growth research is essential for the development of materials with desired properties, such as semiconductors, ceramics, and pharmaceuticals.
Researchers can streamline their crystal growth studies using AI-driven tools like PubCompare.ai, which help locate relevant protocols from literature, preprints, and patents, and provide AI-comparisons to identify the best protocols and products for their needs.
By simplifying the research process and accelerating discoveries, these tools can enhance crystal growth research and lead to innovative breakthroughs.

Example 3
To evaluate the crystal morphology of the example iPP/CNF composites, a ME520 Series polarized light microscope (PLM) (AmScope, USA) was utilized. Sections that were 3 μm-thick were obtained from cross sections of injection molded specimens using a Sorvall MT2-B Ultramicrotome. Each section was placed between a glass slide and a cover slip then transferred to a hot plate (Thermo Scientific) at 200° C. for 2 min before it was cooled at room temperature.
The overall crystallization rate may be dependent on nucleation rate and crystal growth rate. For iPP/CNF3%, the presence of CNF increased the nucleation density without affecting the crystal growth. Therefore, iPP/CNF3% had an accelerated crystallization rate. For iPP/CNF10%, the nucleation density pf iPP was increased by the CNF. At the same time, crystal growth was impeded by CNF. Overall, CNF reduced iPP's crystallization rate when present at 10 wt. %. After MAPP was introduced to iPP/CNF10%, the nucleation density of the composite furthered increased because of a coupling effect. Moreover, the formation of transcrystalline layers facilitated crystal growth.

Single Crystal Growth and Sample Preparation
Form 1 was analyzed by single crystal X-ray diffraction. The crystal was obtained from a DMF solution of Form 1 followed by slow evaporation. The crystal structure was determined at 100(2) K.
