The majority of fly ash pipes in thermal power stations use steel pipes. This makes frequent replacement inevitable due to severe abrasion near the hot and curved section of pipes. Recently, there have been efforts to prevent this abrasion with lining techniques using ceramic or basalt on the inner wall of the pipe. This study uses composite and anti-wear material to maximize the anti-abrasion effects on the hot section of the pipe. The thickness of the abrasion layer was determined by the abrasion ratio of material found through the experiment; the thickness of the reinforcement layer was determined by micromechanics. Experiments were conducted on epoxy resins to test for heat and abrasion. Anti-abrasion test using particle impingement was intended to recreate realistic conditions when abrasion occurs within the hot section of an actual pipe. This study analyzes the abrasion ratio obtained from both the specimen experiment and from on-site measurement and provides evidence that a combination of composites and anti-wear agent can be used to create a fly ash pipe that is lower in costs and higher in quality than what is used currently.

A nano-$MoS_2$/montmorillonite K-10 (K10) composite was prepared and characterized. The composite contains two types of 2H-$MoS_2$ nanoparticles. One is the hollow spherical $MoS_2$ with a size range of 75 nm, and the other is the spherical nano cluster of $MoS_2$ with a size range of 30 nm. The two kinds of nano-$MoS_2$ were formed via assembly of numerous $MoS_2$ nano-platelets with a size of ~10 nm. A tribological comparison was then made among nano-$MoS_2$/K10, K10, nano-$MoS_2$ and a mechanical mixture of K10 and nano-$MoS_2$. K10 reduced the wear but slightly increased the friction. Nano-$MoS_2$ remarkably reduced both friction and wear. The mechanical mixture demonstrated better wear resistance than nano-$MoS_2$, indicating a synergistic anti-wear effect of nano-$MoS_2$ and K10. The synergistic effect was reinforced using nano-$MoS_2$/K10 instead of the mechanical mixture. A part of the $MoS_2$ in the contact region always lubricated the friction pair, and the rest formed a tribofilm. K10 segregated the friction pair to alleviate the ablation wear but magnified the abrasive wear. S-$MoS_2$ protects K10 and they together function as both a lubricant and an isolating agent to reduce the ablation and abrasive wear.

The works of the Futurism were developed along with manifestos and statement in publishing. Futurist aesthetic and ideological agenda on futurist fashion displayed in manifestos on clothes. Futurist fashion propagated in consummate Futurist style through the written manifesto. The Futurists anticipated much of modern fashion phenomenon. In Futurist Men's Clothing, men's clothing is aggressive, agile, dynamic, simple and comfortable, hygienic, gay, luminous, volatile, asymmetric and variable. In Futurist Manifesto on Woman's Clothing, woman is now a principal agent of revolt, a walking synthesis of the audacious, performance-oriented aesthetic of the futurist universe. For Futurist woman's clothing they claimed ingenuity, daring, and economy. The Futurist Manifesto of Italian Hat was continued with their provocative style and radical ambition. Their innovation will rescue a lagging Italian expert and restore the Italian male to his former Iatin Vigor. Speed, dynamic, utility, and funtionality are the main characters. In Futurist Manifesto of Italian Cravat, Futurist cravat is called Anti-cravatta, which is anti-traditional style and made of unconventional materials. In general, the Futurist argued for clothes that promoted simple and functionality. These Futurist fashion project were invention of the new style, avant-garde style, in daily wear and were realized for the renewal of taste in clothing design as a modernizing factors.
