“…FeS 2 -60 is an irregularly shaped massive particle ( Figure 1 d,e) with a size of 60 ± 15 μm. The isoelectric point of FeS 2 particles in water is ~6.6 ( Figure 1 f), which is consistent with the values reported in the literature [ 39 ]. The p K a (where K a is the acid dissociation constant) values of SDP are 2.85 (p K a1 ) and 7.35 (p K a2 ) [ 40 ].…”

Protocell models play a pivotal role in the exploration of the origin of life. Vesicles are one type of protocell model that have attracted much attention. Simple single-chain amphiphiles (SACs) and organic small molecules (OSMs) possess primitive relevance and were most likely the building blocks of protocells on the early Earth. OSM@SAC vesicles have been considered to be plausible protocell models. Pyrite (FeS2), a mineral with primitive relevance, is ubiquitous in nature and plays a crucial role in the exploration of the origin of life in the mineral–water interface scenario. “How do protocell models based on OSM@SAC vesicles interact with a mineral–water interface scenario that simulates a primitive Earth environment” remains an unresolved question. Hence, we select primitive relevant sodium monododecyl phosphate (SDP), isopentenol (IPN) and pyrite (FeS2) mineral particles to build a protocell model. The model investigates the basic physical and chemical properties of FeS2 particles and reveals the effects of the size, content and duration of interaction of FeS2 particles on IPN@SDP vesicles. This deepens the understanding of protocell growth mechanisms in scenarios of mineral–water interfaces in primitive Earth environments and provides new information for the exploration of the origin of life.

“…14c). The occurrence of local serious corrosion can be interpreted as follows: the Ti 0.7 Al 0.3 N coating has a relatively low Al content and moderate oxidation resistance [24]; local defects such as pinholes accelerate corrosion in such a serious corrosion environment [18]. Figure 15 shows the cross-sectional morphologies of the Ti 0.7 Al 0.3 N coating after corrosion with a NaCl deposit in wet oxygen at 650°C for 10 h. Most of the scale formed was thin, dense and continuous, except that the local scale was thick and porous due to serious corrosion.…”

Ti 0.7 Al 0.3 N and Ti 0.68 Al 0.30 Hf 0.02 N coatings were deposited on 1Cr-11Ni-2W-2Mo-V stainless steel by arc-ion plating (AIP), and their oxidation and corrosion performance were characterized using TGA, TEM, SEM/EDS, EPMA and XRD. The oxidation behavior of the coatings at 800°C for up to 100 h was investigated, and the results showed that the introduction of hafnium into the Ti 0.7 Al 0.3 N coating dramatically improved the oxidation-resistance of the coating in air. Compared to the Ti 0.7 Al 0.3 N coating, the presence of Hf in the nitride coating promoted the outward diffusion of Al, and suppressed the outward diffusion of Ti and inward diffusion of O. The Ti 0.7 Al 0.3 N coating was completely oxidized and formed a layered scale after oxidation at 800°C for 20 h in air. Meanwhile, local serious oxidation of the substrate occurred. Corrosion tests of the coatings with a NaCl deposit in wet oxygen at 650°C for 10 h were also conducted, and the results showed that the Ti 0.7 Al 0.3 N coating suffered serious local corrosion, while a thin and dense scale formed on the surface of the Ti 0.68 Al 0.30 Hf 0.02 N coating, and its anti-corrosion performance was remarkably enhanced.

“…The weight gains are 4.2×10 -2 Kgm -2 , 4.08×10 -2 Kgm -2 respectively. But at 1200°C, increasing mass of pure Ti SiC 2 is 0.35Kgm -2 [5]. The gain of Ti SiC 2 -SiC multiphase ceramics is obviously small.…”

The high temperature oxidation behaviors of the Ti3SiC2-SiC ceramic composites fabricated by in situ synthesis under hot isostatic pressing were studied by DSC. The results show that the growth of the oxide scales on Ti3SiC2-SiC ceramic composites obeys a parabolic law in air. The oxidation resistance at 1400°C is better than that at 1200°C for long time. The oxidation resistance of the Ti3SiC2-SiC ceramic composites is much higher than that of monolithic Ti3SiC2. The mechanism of oxidation of Ti3SiC2-SiC ceramic composites is discussed.
