“…Similar observations can be found in the available literature [14,[17][18][19]. the thermal stability of MgO depends on the type and concentration of reagents used for its production, the methodology used for its preparation and the duration of the reaction [23,24]. The magnesium oxide used in this study definitely contributes to an improvement of the thermal stability obtained for all hybrid materials in each specified temperature range.…”

“…The slight weight loss for the inorganic component was only caused by the desorption of water surface-bound to the oxide, mainly in the temperature range up to 200 • C. Very good stability of MgO is mainly associated with the method of its production. In the literature, many studies confirm that the thermal stability of MgO depends on the type and concentration of reagents used for its production, the methodology used for its preparation and the duration of the reaction [23,24]. The magnesium oxide used in this study definitely contributes to an improvement of the thermal stability obtained for all hybrid materials in each specified temperature range.…”

Inorganic–organic hybrids are a group of materials that have recently become the subject of intense scientific research. They exhibit some of the specific properties of both highly durable inorganic materials (e.g., titanium dioxide, zinc) and organic products with divergent physicochemical traits (e.g., lignin, chitin). This combination results in improved physicochemical, thermal or mechanical properties. Hybrids with defined characteristics can be used as fillers for polymer composites. In this study, three types of filler with different MgO/lignin ratio were used as fillers for polypropylene (PP). The effectiveness of MgO-lignin binding was confirmed using Fourier transform infrared spectroscopy. The fillers were also tested in terms of thermal stability, dispersive-morphological properties as well as porous structure. Polymer composites containing 3 wt.% of each filler were subjected to wide angle X-ray diffraction tests, differential scanning calorimetry and microscopic studies to define their structure, morphology and thermal properties. Additionally, tensile tests of the composites were performed. It was established that the composition of the filler has a significant influence on the crystallization of polypropylene—either spherulites or transcrystalline layers were formed. The value of Young’s modulus and tensile strength remained unaffected by filler type. However, composites with hybrid fillers exhibited lower elongation at break than unfilled polypropylene.

“…Both of Mg(OH) 2 and MgO are beneficial inorganic materials to the body [28]. In addition to the conventional medical application of Mg(OH) 2 which has been widely used as an antacid to neutralize stomach acid and a laxative, it also possesses numerous valuable properties including excellent biocompatibility, nontoxic antibacterial activity, and high drug loading ability [29].…”

Abstract:Owing to significant advantages of bioactivity and biodegradability, biodegradable metallic materials such as magnesium, iron, and zinc and their alloys have been widely studied over recent years. Metallic wires with superior tensile strength and proper ductility can be fabricated by a traditional metalworking process (drawing). Drawn biodegradable metallic wires are popular biodegradable materials, which are promising in different clinical applications such as orthopedic fixation, surgical staples, cardiovascular stents, and aneurysm occlusion. This paper presents recent advances associated with the application of biodegradable metallic wires used in dental and orthopedic fields. Furthermore, the effects of some parameters such as the surface modification, alloying elements, and fabrication process affecting the degradation rate as well as biocompatibility, bioactivity, and mechanical stability are reviewed in the most recent works pertaining to these materials. Finally, possible pathways for future studies regarding the production of more efficient biodegradable metallic wires in the regeneration of bone defects are also proposed.

“…This could be attributed to the fact that the MgO and Al 2 O 3 that had been decomposed by the hydration products promoted the sintering activity of the green bodies. Many researchers have reported that the MgO from produced Mg(OH) 2 and the Al 2 O 3 produced from Al(OH) 3 or AlO(OH) have high activity, high surface area and low activation energy, resulting in a high sintering activity [30,31,32,33]. In the current case, with the amounts of deionized water increasing, the amounts of hydration products (brucite, boehmite and bayerite) increased.…”

A novel and aqueous gel-casting process has been successfully developed to fabricate porous MgAl2O4 ceramics by using hydratable alumina and MgO powders as raw materials and deionized water as hydration agent. The effects of different amounts of deionized water on the hydration properties, apparent porosity, bulk density, microstructure, pore size distribution and compressive strength of the samples were investigated. The results indicated that the porosity and the microstructure of porous MgAl2O4 ceramics were governed by the amounts of deionized water added. The porous structure was formed by the liberation of physisorbed water and the decomposition of hydration products such as bayerite, brucite and boehmite. After determining the addition amounts of deionized water, the fabricated porous MgAl2O4 ceramics had a high apparent porosity (52.5–65.8%), a small average pore size structure (around 1–3 μm) and a relatively high compressive strength (12–28 MPa). The novel aqueous gel-casting process with easy access is expected to be a promising candidate for the preparation of Al2O3-based porous ceramics.
