“…Additionally, slower crystallization from a solution forms regular large crystals with a higher internal surface area. Out of the benefits of the mentioned approach, researchers have highlighted the possible total control of the synthesis conditions for a long-term process, allowing the development of reproducible protocols [ 27 , 28 , 29 ]. The hydrothermal and solvothermal approaches have been used for synthesizing several MOFs.…”

Many studies have addressed electrochemical biosensors because of their simple synthesis process, adjustability, simplification, manipulation of materials’ compositions and features, and wide ranges of detection of different kinds of biomedical analytes. Performant electrochemical biosensors can be achieved by selecting materials that enable faster electron transfer, larger surface areas, very good electrocatalytic activities, and numerous sites for bioconjugation. Several studies have been conducted on the metal–organic frameworks (MOFs) as electrode modifiers for electrochemical biosensing applications because of their respective acceptable properties and effectiveness. Nonetheless, researchers face challenges in designing and preparing MOFs that exhibit higher stability, sensitivity, and selectivity to detect biomedical analytes. The present review explains the synthesis and description of MOFs, and their relative uses as biosensors in the healthcare sector by dealing with the biosensors for drugs, biomolecules, as well as biomarkers with smaller molecular weight, proteins, and infectious disease.

“…Different synthesis routes provide a crucial basis of the morphologies and crystallinity of perovskite, which plays a functional role in photocatalytic performance. Hydrothermal synthesis is widely employed to prepare morphology-controlled perovskite materials and even adjust crystal from the nanoscale to the micron-scale 157 . A diverse range of perovskite material with different morphologies and crystallinity (i.e.…”

“…BTO can be prepared using different methods [ 7 ]. Thus, a large variety of BTO nanostructures, such as nanodots [ 8 , 9 ], nanoparticles [ 10 ], nanobowls [ 11 ], nanorods [ 12 ], nanocubes and nanowires [ 13 ], possessing different crystalline phases (e.g., cubic [ 14 , 15 ], tetragonal [ 16 ] and polycrystalline [ 17 ]), have been produced through various chemical approaches, such as organometallic [ 18 , 19 ], solvothermal/hydrothermal, templating [ 14 , 15 , 17 , 20 ], molten salt [ 14 , 21 ] and sol-gel methods [ 22 , 23 ].…”

In this study, nano-BaTiO3 (BTO) powders were obtained via the solvothermal method at different reaction times and were investigated using transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectroscopy. The results were compared with those obtained for a larger crystallite size BTO powder (BTO-m). The sizes of the cuboid crystallites (as determined by XRD and TEM) ranged from about 18 to 24 nm, depending on the reaction time. The evolution with temperature of the structure parameters of nano-BTO was monitored by means of X-ray diffraction and Raman spectroscopy and no signs of phase transition were found up to 170 °C. Careful monitoring of the dependence of the XRD peak widths on the hkl indices showed that the effect of the cubic crystallite shape upon the XRD peak widths was buried by the effect of hidden tetragonal line splits and by anisotropic microstrain. The good correlation of the line widths with the tetragonal split amplitudes, observed especially for BTO-m above the transition temperature, indicates tetragonal deformations, as also revealed by Raman spectroscopy. The large anisotropic microstrain shown by the nano-powders, which had a maximum value in the <100> directions, was considered evidence of the phenomenon of surface relaxation of cubic crystallites edged by {100} faces. The observed behavior of the nano-BTO structures with increasing temperature may suggest a correlation between the surface relaxation and tetragonal deformation in the nano-cubes. The experimental results for both nano-BTO and mezoscale-BTO are in agreement with the core-shell model.
