Crystal cohesion of the compound is achieved through N-H…Cl hydrogen bonds between the anions and cations and through cycle stacking interactions between organic cations. The vibrational properties were studied by Fourier Transform Infrared (FTIR) spectroscopy. The three-dimensional Hirshfeld surface (3D-HS) analysis and the two-dimensional fingerprint plots (2D-FP) were generated to quantify the weak intermolecular interactions present in the crystal.

Hence, bone health represents one of the major challenges to elderly citizens due to the increase of injury associated with bone degeneration, such as fragility and risks of fractures. In the virtue of improving the regenerative function of bone tissues, a specialized field of bone tissue engineering (BTE) has been introduced to improve the current strategies in treating bone degenerative disorders. Most of the research performed in BTE focuses on the optimization of key components to generate new bone formation, including the scaffold. A scaffold plays a significant role in establishing the structural form that interconnects major elements of the tissue engineering triad. To date, many types of biomaterials have been explored in BTE, ranging from natural and synthetic materials to nanocomposites.

However, like most ceramic materials, originating from low symmetry (D88) in its crystal structure, Ti5Si3 has poor fracture toughness and limited flexibility at room temperature, and at high temperatures, its creep resistance also drops sharply, which hinders its application. To overcome these shortcomings, it is suggested that TiC is a practical addition to Ti5Si3 to overcome the brittleness. Compared with monolithic Ti5Si3, Ti5Si3/TiC composites have a higher fracture toughness. Ti5Si3/TiC composites can be prepared by many ways, which commonly require high energy cost, complex processes and provide low efficiency. Therefore, the search for environmentally friendly strategies for the production of Ti5Si3/TiC is still ongoing.\u0000\u0000\u0000\u0000This article proves that we can successfully prepare Ti5Si3/TiC composites from CaTiO3/SiO2/C precursor by using SOM technology and explores the reaction mechanism of electrochemical process.\u0000\u0000\u0000\u0000In the process of electroreduction of CaTiO3/SiO2/C particles into Ti5Si3/TiC composites, we mainly used SOM technology at 1273 K and 4.0 V in molten CaCl2 and under an argon atmosphere.\u0000\u0000\u0000\u0000The results show that the Ti5Si3/TiC composites can also be successfully electrosynthesized from CaTiO3/SiO2/C precursors by using SOM-based anode systems at 1273 K and 4.0 V in molten CaCl2.\u0000\u0000\u0000\u0000The Ti5Si3/TiC composites can been successfully electrosynthesized from CaTiO3/SiO2/C precursors by using SOM-based anode systems at 1273 K and 4.0 V in molten CaCl2.\u0000\u0000\u0000\u0000This work demonstrates that Ti5Si3/TiC composites have been successfully electrosynthesized from CaTiO3/SiO2/C precursors using SOM-based anode systems at 1273 K and 4.0 V in molten CaCl2. The Ti5Si3/TiC has a smooth surface and micro/nano-porous structure. The formation routes for Ti5Si3 and TiC are independent. In summary, the SOM-assisted controllable electroreduction process has the potential to provide a novel one-step route from CaTiO3/SiO2/C precursors to Ti5Si3/TiC composites in molten salts.\u0000\u0000\u0000\u0000In summary, this paper demonstrates that Ti5Si3/TiC composites have been successfully electrosynthesized from CaTiO3/SiO2/C precursors by using SOM-based anode systems at 1273 K and 4.0 V in molten CaCl2.the main intermediate stages in the electrolysis process include Ti2O3, Ca2SiO4, and SiC. The above steps of CaTiO3, SiO2, C → Ti2O3, Ca2SiO4, SiC → Ti5Si3/TiC make up the electroreduction process.Compared with the initial powders before electrolysis, the obtained Ti5Si3/TiC composite has a smooth surface and possesses a nodular microstructure.\u0000","PeriodicalId":36699,"journal":{"name":"Current Materials Science","volume":"132 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72994846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To solve the difficulties mentioned above, we proposed IG-Jaya, a new hybrid FS model based on wrapping information gain with the Jaya optimization algorithm (parameterless) to obtain the optimal features from the microarray\u0000data set.\u0000\u0000\u0000\u0000The objective behind considering Jaya is to minimize the\u0000computing cost and the risk of tuning the algorithm’s parameters to achieve\u0000better accuracy.

The resulting feature subset can\u0000be considered an input for the classification model.The primary contributions of the study are 1.Using IG as a technique, we developed a filter-based paradigm to employ feature selection by removing redundant and irrelevant features from microarray cancer datasets. 2. This new hybrid meta-heuristic FS model, namely IG-Jaya, is proposed for the efficient diagnosis of cancer disease. 3.
