Electric current assisted sintering of β-Si5AlON7-TiN ceramic composites from raw materials prepared by combustion synthesis was investigated. A high level of relative density (92% and higher) was achieved by using of two types of electric current assisted sintering technique: high voltage electric discharge consolidation, as well as spark plasma sintering. While only spark plasma sintering, it may be considered as promising technique for obtaining ceramic composites and items with high level of strength properties.

“…These XRD results indicate that the NH 4 Cl acted as a nitrogen source to produce TiN with various possible routes, including the decomposition to NH 3 and HCl. 48,49 As c increased, the amount of NH 4 Cl should increase before pyrolysis, and thus, surface nitrogen content on the oxidized TiN after pyrolysis also increased. Therefore, unexpectedly, c significantly boosted the activity.…”

An active site formation process for recently reported carbon-support-free titanium oxynitride (TiO x N y ) catalysts is investigated to reveal the critical factors for enhancing the oxygen reduction reaction (ORR) activity in acidic media. Neither the titanium source nor the presence of a conductive oxide support is a key to displaying activity whereas an oxidized TiN surface is revealed to be necessary. The ORR activity is successfully enhanced without using a carbon support to the level of the best carbon-supported oxide-based catalyst, zirconium oxynitride on multiwalled carbon nanotube in 0.1 mol dm–3 H2SO4 solution, mainly by optimizing hydrochloric acid concentration in the precursor dispersion to increase the surface nitrogen content. The catalyst is stable; i.e., the activity remained unchanged after 20 000 potential cycles between 0.6 and 1.0 V versus reversible hydrogen electrode.

“…Furthermore, TiN powders with a size of 100 nm were produced using a self-propagating high-temperature method, wherein titanium powder was burned together with NH 4 Cl in a nitrogen environment. 108 The resulting product had an approximate specific surface area of 85 m 2 /g. The overall process can be described by the following general reaction scheme:…”

This Review aims to investigate the use of titanium nitride-based nanofluids (NFs) in solar energy systems to enhance their efficiency and heat transfer capabilities. By exploring the thermophysical properties of TiN nanoparticles (NPs), the Review seeks to promote the adoption of NFs over traditional working fluids, thus contributing to the development of sustainable energy solutions. The emphasis is on leveraging TiN's superior plasmonic properties, which enable it to absorb sunlight more efficiently than conventional materials, thereby enhancing the overall performance of solar collectors. By highlighting TiN's exceptional chemical and mechanical stability and cost-effectiveness compared to noble metals, the Review aims to underscore its potential as a promising alternative for improving NFs' thermophysical characteristics and boosting the efficiency of solar thermal systems. For instance, TiN NPs characterized by broad-spectrum LSPR have exhibited a notable 92% sunlight absorption within the wavelength range of 400−750 nm, leading to a temperature change of up to 260% compared to water. Moreover, incorporating TiN NPs into rGO-based plasmonic nanofluids demonstrates a remarkable photothermal conversion efficiency (67%) and enhanced heat transfer properties, showing a 23% improvement over pure water at a concentration of 40 ppm. This Review also addresses the current challenges and provides insights into future research directions, fostering the potential application of TiN NPs in advanced solar harvesting technologies. By consolidating existing knowledge, the Review aims to pave the way for innovative and sustainable solutions in the field of renewable energy, thereby contributing to global efforts to combat climate change and promote environmental sustainability.
