In this paper, two new Rivaroxaban crystalline forms are reported and characterized by the single‐crystal X‐ray diffraction (SXRD), powder X‐ray diffraction (PXRD), thermogravimetric analysis, and differential scanning calorimetry (TGA/DSC), which are synthesized with formic acid and acetic acid, named as forms F and G, respectively. The intermolecular forces for forms F and G are analyzed by Hirshfeld surface analysis method, showing that the force of O···H is significantly stronger than that of H···H. Furthermore, the stability, solubility, and bioavailability of the two crystal forms are also studied. The clinical experiments show that form F is more effective than other reported crystal forms in inhibiting the activity of thrombin and thrombosis, which is expected to replace the marketed crystalline forms in clinical application.

Dielectric, thermal, and mechanical behavior of an efficient nonlinear crystal, nickel boro phthalate (NBP), grown by a slow evaporation solution growth technique, is characterized for optoelectronic applications. Ultraviolet absorption study identifies the lower cutoff wavelength as 281 nm. This low value along with transparency in the visible and infrared regions establishes that NBP is a probable nonlinear material. The frequency and the temperature dependency of dielectric constant and dielectric loss are probed. AC conductivity and activation energy are computed, to examine the semiconducting ability of the crystal. Thermal gravimetric analysis and differential thermal analysis are carried out to determine the decomposition temperature. Mechanical characterization is performed by the Vickers microhardness test. The study reveals that NBP comes under the category of soft material. Mechanical properties such as the elastic stiffness constant, brittleness index, yield strength, and fracture toughness are explored.

The stability of solvates is very important in the field of crystal engineering. Molecular interaction and packing mode are important factors affecting the stability of solvates. In this study, 2,7‐dibromo‐9H‐carbazole is selected as the model compound to investigate the influence of molecular stacking mode on the stability of solvates. An anhydrous form and five solvates of 2,7‐dibromo‐9H‐carbazole are obtained by recrystallization. The desolvation phenomena of the five solvates are studied by thermogravimetric analysis, hot stage microscope, and infrared spectroscopy and it is found that the stability of the solvates is N,N‐dimethylacetamide solvate > dimethyl sulfoxide solvate > N,N‐dimethylformamide solvate > dioxane solvate > acetonitrile solvate. Crystal structures are analyzed by single crystal X‐ray diffraction and Hirshfeld surface analysis is also applied to analyze the intermolecular interactions in the crystals. The results show that the stability of the five solvates is related to the packing modes of the molecules in the crystal. It is suggested that the solute molecules and solvent molecules in the unstable solvates are arranged in the interlayer mode, while they are arranged in a staggered mode in stable solvates.

As an ecological and environment‐friendly building material, sticky rice mortar has attracted the attention of many researchers. Amylopectin is the most important organic matter of it, which can improve the mechanical properties and durability of sticky rice mortar by inducing mineralization of calcium carbonate (CaCO3). However, amylopectin induced formation of CaCO3 has not been reported. In this paper, mineralization of CaCO3 induced by gelatinized amylopectin is investigated. For comparison, the different morphologies of CaCO3 are studied in the presence of Mg2+, Fe3+. Moreover, these CaCO3 products with different morphologies are used to clean the waste water. The results indicate that gelatinized amylopectin is conducive to formation of pumpkin‐like vaterite. It forms uniform rod and dumbbell‐shaped calcite in the presence of Mg2+, form calcite with stepped depressions in the presence of Fe3+. The adsorption of Pb(II) can reach extremely high level (1445.86 mg g−1) with the rod‐like calcite.

In this work, the dislocation etching pit morphology and etching kinetics on the A‐{11 2¯ 0} plane of sapphire crystal (α‐Al2O3) are studied experimentally. The results show that the etch pit exhibits a subrhombic 3D morphology, which is consistent with the atom arrangement symmetry of the A plane. Further analysis shows that the two adjacent sides of the rhombic etch pits correspond to the directions [3 3¯ 0 1¯ ] and [3 3¯ 02], respectively; both of them are in the atomic close‐packing direction of A plane. The etch pits are controlled by a chemical reaction between Al2O3 and potassium hydroxide (KOH) with the reaction activation energy of 51.7 kJ mol−1, which is developed in a manner of kinematic wave by the step moving with a constant speed.

A simple method for synthesis of titanium carbide (TiC) nanofibers by a modified carbothermal reduction of electrospun titanium‐based fibers is reported. The effect of synthesis steps on the final product is discussed. Continuous TiC fibers synthesized have a smooth surface morphology, with average diameter of 148 nm and length in the centimeter range. X‐ray diffraction and high‐resolution transmission electron microscopy analysis results indicate that the fibers consist of TiC of high purity. Impact of heat treatment on the morphology and chemical and crystalline composition of the product is also investigated. Based on the experimental evidence, it is hypothesized that the carbothermal reduction of calcined electrospun fibers with precoated carbon proceeds through diffusion‐limited shrinking core pathway while that of the as‐spun fibers follows the reaction‐limited solution precipitation mechanism. The TiC nanofibers also show superior sintering properties by increasing theoretical density of hot pressed TiB2 from 94.5% of theoretical density to 97.9% of theoretical density. When sintered with ceria, it improves the conductivity of the ceria by 18.29 times as compared to 2.94 times by TiC nanoparticles at 800 °C. The TiC nanofibers show metallic behavior as well as potential for application as electrochemical double layer capacitor supercapacitors.

This article deals with synthesis, growth, structure, and characterization of 5‐chloro‐3‐methoxy‐4‐hydroxybenzaldehyde (5CMHBA or 5‐chlorovanillin) single crystals. A facile one‐pot method is employed for the chlorination of vanillin using N‐chlorosuccinimide. After chlorination, the single crystals of 5CMHBA are grown by slow evaporation solution growth technique. Grown crystals are subjected to single crystal X‐ray diffraction (SXRD), Fourier Transform Infrared (FTIR), and Thermogravimetric‐Differential Thermal Analysis (TG‐DTA). 5CMHBA crystallizes in the tetragonal crystal system with the space group P42/n. Vibrational characteristics are studied using FTIR. Further, thermal studies of the crystal are carried out using simultaneous TG‐DTA thermal analyzer. The molecular structure and its intermolecular interactions are studied by applying time–dependent density functional theory (TD‐DFT) using Gaussian 09 program and Hirshfeld surface analysis. A lesser energy gap of the 5CMHBA compared to that of vanillin shows the high reactivity of the molecule. Dipole moment, polarizability, and hyper‐polarizability are calculated in the molecular level and found to have greater polarizability than vanillin and also higher in order than that of standard urea molecule. This reveals the suitability of the molecule for nonlinear optical applications. The intermolecular interactions and porosity are analyzed and compared with vanillin and its polymorphs by Hirshfeld surface analysis.

High uniformity graphene has extensive application prospect in many important fields due to its excellent features. During large‐area graphene synthesis by chemical vapor deposition, the optimization of the substrate temperature can improve the uniformity of graphene. Here, machine learning is used to design and optimize the substrate surface temperature for uniform graphene deposition. The computational fluid dynamics simulations based on a developed computational model are first performed to obtain the training data for machine learning, such as the gas temperature, velocity, concentrations, etc. Then, the neural network model is used to optimize the substrate temperature using the simulated data. It is found that the high accuracy is achieved through the validation of testing set. The optimal substrate temperature distribution is finally obtained, in which the carbon deposition rate and its uniformity are optimized to the specified values.
