“…This result indicates that trehalose treatment did not affect the anti-icing activity of ABP- Cn -AFP G124Y . To further explore the possibility that directly immobilized AFP on Al prevents ice or frost formation, we examined time-dependent ice formation in a cold chamber for 3 h. Notably, Cn -AFP-immobilized on the Al surface (ABP- Cn -AFP G124Y with trehalose) prevented ice formation, whereas ice formed on bare Al and hydrophilic Al surfaces coated with a thin ZrO 2 film, which is a universal surface-coating method for Al 26 27 28 29 30 ( Fig. 7 ).…”

Cryoprotectants such as antifreeze proteins (AFPs) and sugar molecules may provide a solution for icing problems. These anti-icing substances protect cells and tissues from freezing by inhibiting ice formation. In this study, we developed a method for coating an industrial metal material (aluminum, Al) with AFP from the Antarctic marine diatom, Chaetoceros neogracile (Cn-AFP), to prevent or delay ice formation. To coat Al with Cn-AFP, we used an Al-binding peptide (ABP) as a conjugator and fused it with Cn-AFP. The ABP bound well to the Al and did not considerably change the functional properties of AFP. Cn-AFP-coated Al (Cn-AFP-Al) showed a sufficiently low supercooling point. Additional trehalose coating of Cn-AFP-Al considerably delayed AFP denaturation on the Al without affecting its antifreeze activity. This metal surface–coating method using trehalose-fortified AFP can be applied to other metals important in the aircraft and cold storage fields where anti-icing materials are critical.

Durability in terms of life is intended as a significant factor in developing advanced materials. The enrichment in corrosion resistance of the produced progressive material can be the solution. In the current study, a nanocomposite of aluminum 6061 and cerium oxide was prepared with a stir casting route reinforced in the range of 1-3 wt.%. The corrosion and microstructural behavior were observed under parametric conditions. The exposure time (36-180 hours), temperatures (room temperature, 45 ºC, and 75 ºC), and 2.5 wt.% of Sodium chloride (NaCl) and Sulphuric acid (H2So4) solutions were chosen as parameters for examining the corrosion rate using the immersion test method. The lower corrosion resistance was noticed in aluminum metal matrix nanocomposites (AlMMNCs) reinforced with 3 wt.% of CeO2. The SEM analysis concluded voids, holes, clustering of particles, and debris kind of defects were observed in stir casting of AlMMNCs samples. The Pitting, fretting, and grain boundary corrosions were the primary degradation factors for corrosion behavior as evaluated from microstructural characteristics. The 0.116 has been observed as a significant corrosion rate in mm potential per year after 180 hours as exposure time at 75ºC in 2.5 wt.% NaCl solution.

This research presents an experimental and theoretical evaluation of the effect of poly-composition thermal barrier coatings on the performance and emission characteristics of the compression ignition engine. This work investigated the thermal and physical behavior of thermal barrier coating. The thermal barrier coating was coated into two layers, and the thermal plasma spray method was used to make the coating. The first layer is AT13, and the top layer is Yttria-stabilized zirconia. The coated and uncoated pistons were analyzed in the Ansys, and it has shown the temperature distribution of the pistons. The experimental report shows that the brake thermal and volumetric efficiency was increased by 7.52% and 1.06%, brake-specific fuel consumption was reduced up to 18.91%, emission of carbon monoxide was reduced by 50%, and hydrocarbon was reduced by 52.38%.
