“…84 To create a more cohesive and porous material, chitosan and polyethylene glycol were combined with these ceramic microspheres to create a better injectable and mechanically stable implant. 84 For example, while chitosan alone is anti-inammatory it has low mechanical stiffness and calcium-phosphate ceramics are brittle with low porosity, its combination with chitosan can yield a composite with benets of both to create a more stable material able to regenerate greater host bone with minor inammation. Many novel materials developed currently, include hydroxyapatite coatings 47,60 and metal or ceramics particles 45,46,[53][54][55]75 incorporated into polymeric base materials to increase mechanical stability and osteogenesis.…”

“…Structure imperfections due to the presence of vacancies, impurities of implementation and substitution, and determined by them distortions in the crystal lattice became energetically advantageous for the formation of HAP in the hexagonal syngony. Therefore, the presence of microimpurities and other defects in the structure of biological apatite Atoms of impurity can be located randomly in the structure of hydroxyapatite [61]. To describe the structure of HAP, it is convenient to formulate the ideal stoichiometric formula of Ca 10 (PO 4 ) 6 (OH) 2 , taking into account the different positions occupied by calcium atoms in the lattice of HAP as Ca 10 (PO 4 ) 6 (OH) 2 , and also calculating the Ca/P ratio, which for our samples was 1.5.…”

The article presents the investigation results of the formation and synthesis of nanosized materials which were obtained at the Institute of Combustion Problems, many works have been brought to practical use. Investigations of low-temperature soot formation become the basis of nanomaterial synthesis methods, developed at the Institute for Combustion Problems since 1985. Flame can be considered as a chemical reactor to produce target products. The main feature of the processes based on technological combustion is that the target product is formed as a result of the combustion reaction, occurring spontaneously at high temperatures with a high speed without consuming external energy, i.e. due to its own heat. With the development of nanotechnology, new challenges have emerged in the synthesis of nanomaterials under combustion synthesis conditions. Below is a list of works on nanomaterials synthesis carried out at the Institute: complete scheme of soot formation; energy intensive nanocarbon materials; development and study of perovskite photocatalysts for hydrogen evolution; obtaining carbon fibers by the method of electrospinning; obtaining of biologically soluble membranes based on polymeric nanofibres and hydroxyapatite of calcium; synthesis of nanocarbon sorbents for purification of water from heavy metal ions.

“…Em geral, essa valorização dos dois bairros em estudo foi melhor capturada pela PVG obtida pela krigagem da modelagem GWR. Krigagem: RMSE para os valores preditos pela amostra de trabalho.Fonte: Autores(2020).Observa-se que a modelagem GWR apresentou RMSE menor, indicando que esse modelo foi capaz de fazer predições mais próximas do esperado. Calculou-se o RMSE dos valores preditos pelas krigagens para a amostra de validação.…”
