Summary: This study characterized the tribological behaviors of a Zr-based BMG material against GCr15 steel balls under different loads and frequencies. It was found that high coefficient of friction (COF) was observed under low load and high frequency, while low COF was observed under high loads or at low frequencies. The specific wear rate increased with both load and frequency, with frequency playing a more crucial role. Transition of wear mechanisms from oxidative wear and abrasive wear to adhesive wear was detected with increasing load and frequency, and the role of plastic deformation of BMG was illustrated. This study helps to understand the tribological properties of Zr-based BMGs under sliding conditions.

Summary: The FeMnCrSi alloy deposited by Cold Gas Spray (CGS) process using N2 working gas at 1000 degrees C showed higher hardness, elastic modulus, cavitation resistance, and sliding wear resistance compared to deposition at 900 and 1100 degrees C. Samples sprayed with N2 at 1000 degrees C and He at 600 degrees C demonstrated higher compressive residual stress and flatness ratio as well. Tests were conducted on CGS sprayed 316 L stainless steel as a benchmark material.

Summary: In this study, fine and coarse Cr3C2-25NiCr particles were sprayed using HVAF and oxygen-augmented HVAF(O) modes. Heat treatment was conducted to enhance the microstructural features and mechanical properties of the coatings. The phase composition, microstructural features, and mechanical properties of the as-deposited and heat-treated coatings were extensively examined. Subsequently, a high-load sliding test was performed to assess the influence of processing conditions and heat treatment on the sliding wear performance of Cr3C2-25NiCr coatings. Detailed post-wear analyses were then conducted to analyze the wear rate/mechanism. The results demonstrated that the appropriate choice of process parameters and heat treatment conditions improved the sliding wear performance of Cr3C2-25NiCr coatings.

Summary: This study investigated the tribological properties and wear mechanisms of ex-situ additively manufactured FeCrMoCB/Cu bulk metallic glass composite under different normal loads and sliding speeds. The findings showed that the composite exhibited good wear resistance, with the coefficient of friction decreasing and the wear rate increasing as the sliding speed increased. Additionally, the wear mechanisms shifted from abrasive wear to oxidation wear and adhesive wear with increasing normal load, and adhesive wear and fatigue wear became dominant as the sliding speed increased.

Summary: Ti45Zr16Cu10Ni9Be20 bulk metallic glass with deep cryogenic-cycling treatment (DCT) exhibited increased wear resistance at the cost of decreased hardness in macroscopic wear tests. The wear mechanism shifted from severe fatigue wear to mild ductile ploughing, while oxidation wear played a minor role. The competition between lower hardness and higher elastic recovery resulted in a lower friction coefficient, indicating the potential of DCT in designing wear-resistant BMGs.

Summary: An attempt was made to improve the efficiency of electrochromic (EC) windows by fabricating Nb-NTO thin films using ion-assisted pulsed DC unbalanced confocal magnetron sputtering. A metallic seed layer was incorporated between the substrate and the film to enhance the EC efficiency. The Nb-NTO film showed better EC properties, stability, and recyclability compared to the as-prepared NTO film. The successful fabrication of Nb-NTO devices with a polymer gel electrolyte holds promise for the commercialization of EC windows.

Summary: Delivery of genetic material is an important tool for analyzing and understanding genetic interventions. Traditional methods rely on viral vectors or xenogenic carrier molecules, which can have carcinogenic, immunogenic, and toxic effects. Cold atmospheric plasma-induced transfection is a new physical method that does not require vectors or carriers. It creates temporary pores on cell membranes for gene delivery. This method has been successfully used in various cell lines and mouse models without adverse effects on cell activity and function.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
