Here, we assess melting point predictions from direct MD simulations of nitromethane and acetic acid. This study has three objectives: to evaluate popular force fields (CGenFF, OPLS, GAFF), to assess various MD approaches (simulations of solid/liquid, vapor/solid/liquid/vapor, vapor/solid/vapor, and solid alone), and to compare the crystal growth and melting of both compounds, focusing specifically on the time scale and anisotropy. Our results indicate that none of the popular force fields accurately predict melting points, highlighting the need for improvement. All MD simulation approaches yielded consistent melting points of either compound, except for the solid-alone simulation, while continuous heating of the vapor/solid/vapor system proved effective. The time scales of crystal growth and melting differ significantly between the molecules: 20 ns for nitromethane and 200 ns for acetic acid. Anisotropy in crystal growth and melting is non-negligible and much more pronounced for acetic acid compared to nitromethane.

While strong hydrogen bonds have traditionally been the primary focus, recent attention has shifted toward weaker interactions, such as C–H···F interactions. Fluorine, previously believed to be incapable of forming hydrogen bonds, has now been recognized for its ability to engage in weak C–H···F interactions, significantly influencing crystal packing. This study explores the intricate nature of C–H···F interactions and their relationship in the presence of other intermolecular interactions. We have synthesized and structurally characterized six new fluorine-containing organic compounds and examined how the positions of fluorine and trifluoromethyl groups (<i>ortho</i>, <i>meta</i>, and <i>para</i>) affect intermolecular interactions. The solid-state structures of these compounds have been explored by investigating the noncovalent interactions present in the crystal. The weak C–H···F interactions, shaped by the electronic environment and the acidity of the donor hydrogen atoms, contribute to the enhanced stability of the crystal structure. To quantify these interactions, we have evaluated the lattice energies via PIXELC, performed the topological analysis via the QTAIM approach, and analyzed the molecular electrostatic potential (MESP) as well. The thermal stability of the compounds has been assessed in the context of noncovalent interactions present in the crystal structure. By elucidating the role of C–H···F interactions, this research aims to contribute to the advancement of supramolecular chemistry and crystal engineering of interactions involving organic fluorine. The study investigates only six fluorinated compounds, which significantly limits its ability to represent the broader and more complex trends within crystal engineering.</p>","PeriodicalId":34,"journal":{"name":"Crystal Growth & Design","volume":"25 12","pages":"4263–4282 4263–4282"},"PeriodicalIF":3.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144305680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An example of such a system are monoglyceride (MG)-based oleogels, which are free-flowing lipids (e.g., vegetable oils) structured with a lipid-crystal network. In this work, we use MG oleogels as an example system to investigate the acoustophoretic effect on the structuration of a growing crystal network. For this purpose, multifaceted characterization is conducted utilizing optical and coded excitation scanning acoustic microscopy as well as small-angle X-ray scattering, respectively. The optical microscopy results show that USW produces local density differences of the structuring crystalline material and induces the orientation of the MG platelets. X-ray diffraction measurements confirm these findings and show a 23% average increase in MG platelet correlation length, which can be linked to platelet thickness, as well as an increase in the MG nanoplatelet surface smoothness. These findings produce a foundation for better understanding the effect of acoustophoresis in dynamically developing lipid-based materials and illuminate the mechanical changes that arise because of USW treatment.</p><p >Ultrasound standing waves (USW) generate forces displacing micrometer-sized particles in fluid─a phenomenon called acoustophoresis.

Nucleation kinetics of the cocrystal and pure coformers analyzed using classical nucleation theory (CNT) revealed that the nucleation rate of the cocrystal is significantly lower, approximately 1/111 times that of pure ASA and 1/21 times that of SMZ at similar supersaturations. Cooling cocrystallization was scaled up from 20 mL to 2 L, transitioning from a magnetically stirred to an overhead-stirred system. This scale-up facilitated the study of nucleation and the successful production of cocrystals in larger volumes. Cooling in the stable cocrystal region in the TPD produced pure cocrystals. Cooling crystallization in the SMZ + cocrystal region near the SMZ invariant point in TPD led to the formation of pure cocrystal instead of SMZ-cocrystal mixture due to the influence of nucleation kinetics.
