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: In this study, an Ir-Ta-Ni-Nb bulk metallic glass (BMG) with outstanding high-temperature wear resistance was demonstrated and its potential applications in extreme environments were revealed. The wear behavior and mechanism were systematically investigated from room temperature to 750 degrees C. The results showed an improvement in wear resistance at a higher temperature of 750 degrees C, attributed to the formation of an oxide layer, which avoids violent wear of the BMG.

Summary: Two different CrB2 composite coatings were prepared on TC4 alloy substrates using atmospheric plasma spraying with CrB2Cr3C2 and Cr-B4C composite powders. The CrB2Cr3C2 composite coating showed minimal change in phase composition compared to the composite powder, while the CrB4C composite coating had a more uniform microstructure with higher hardness and toughness due to an in-situ exothermic reaction between Cr and B4C during the spray process.

Summary: A novel Ni-Co-metallic glass composite was fabricated, and the effect of adding Ni60Cr10Ta10P16B4 amorphous metallic glass powder (MGP) on the morphology and electrocatalytic properties of Ni-Co coatings was investigated. The Ni60Cr10Ta10P16B4 was produced through mechanical alloying of elemental powders and then Ni-Co nanocomposite coatings were deposited on a copper substrate using electrodeposition with different amounts of MGP. The microstructure and composition of the coatings were analyzed using XRD, SEM, and EDS, while the electrocatalytic performance was evaluated through CV in a methanol-containing alkaline solution. The addition of MGP was found to enhance the electrocatalytic activity of the Ni-Co coating, with the optimal performance achieved at 7.5 g L-1 MGP concentration. Furthermore, MGP was shown to alter the microstructure and Co content, as well as increase the roughness and specific surface area of the coatings.

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: Deposition of Pd/Pt/Au three-layer films on p-GaN under high and ultra-high vacuum conditions was studied to investigate the electrical contact properties. Linear I-V curves were observed in samples deposited under ultra-high vacuum conditions, while nonlinear I-V characteristics were obtained in samples deposited under high vacuum conditions. The study also found that the samples deposited under high vacuum conditions had higher amounts of oxygen and Pd oxide. The oxide layer had an additional influence on the electrical characteristics of the Pd/Pt/Au/p-GaN contact.

Summary: The corrosion behavior and microstructural evolution of Sc microalloyed Al-3.2Cu-1.5Li alloys were investigated in detail. The microstructural results showed higher levels of dislocations density in the Sc microalloyed sample, which resulted in significantly refined grains and T1 precipitates. Microalloying with Sc changed the corrosion mode of the alloy and localized corrosion was found to occur preferentially at the subgrain within unrecrystallized grains with high grain stored energy.
