Summary: Composites of yttria-neodymia co-stabilized zirconia with nanoscale tungsten carbide and alumina addition were manufactured and characterized. Alumina addition increased hardness and Young's modulus, and slightly increased bending strength. However, it reduced the transformability of the zirconia matrix and fracture toughness. In EDM, alumina reduced re-solidified layer thickness, surface defects, and improved surface smoothness, but had negligible effect on material removal rate.

Summary: In the abrasive machining of monocrystalline silicon, the surface and subsurface behavior can be changed by utilizing the impulse discharge between the wheel metal and semiconductor silicon. This method drives a loose-abrasive flow, which results in nano-scale surface removal and thermal modification. The research focuses on the formation behavior of the abrasive-Si interface to improve the surface and subsurface integrity. The results show that the hybrid machining approach with mechanical cut-copying and impulse-discharge thermal modifying action can greatly enhance the surface integrity and form accuracy.

Summary: This study utilized a sialon-based end-milling ceramic tool to machine nickel-based GH4169 superalloy at a cutting speed of 500 m/min without any cutting fluid. The wear patterns of the ceramic tool included flank wear and breakage, while the wear mechanisms were mainly adhesive wear and diffusion wear. Additionally, severe adhesion of superalloy material on the tool and the presence of Ni, Fe, and Cr elements from the superalloy were observed, indicating the complex nature of wear mechanisms involved.

Summary: The study investigates the potential of cryogenic-treated tool electrodes with modified and unmodified dielectrics in electric discharge machining of Ti6Al4V. Statistical analyses based on full factorial design of experiments are performed, and the cutting mechanism is found to be highly dependent on the surfactants in the dielectric. The desirability-based process optimization reveals that the modified process with surfactant yields lower roughness on the workpiece compared to the unmodified process, with the S-60 surfactant achieving the best results.

Summary: A strategy is proposed to generate single microdrops with femtoliter to microliter volumes as a liquid reactor and to guide them towards a reactive surface within a viscous carrier liquid. Reactions of the drop content with the surface are exemplified by exhaustive electrolysis of the reactor content, making use of an ion-conducting pathway through the carrier liquid. The mechanisms by which the redox-active species from the aqueous drop reach the electrode surface were established by a combination of time-lapse microscopy of the drop shape, chronoamperometric recording of the single drop electrolysis, and modelling of the reaction-transport problem, showing that partitioning over the liquid-liquid interface must be a key step in this mechanism. The possibilities of reagent delivery and external triggering of a reaction are expanded by the possibility for controlled addition of further dissolved reactants to the liquid microreactor.

Summary: The breakup process of an inviscid liquid bridge sandwiched between two coaxial rods is investigated, with a focus on its profile close to rupture and its influence on subsequent breakup behaviors. The profile of the liquid bridge undergoes a transition from symmetry to asymmetry as the distance between the rods increases. A critical slenderness is found above which the liquid bridge becomes asymmetric and exhibits a well-fitted profile of a sine wave cycle. Experimental and theoretical results show that the ratio of bridge length to equivalent radius is always 2 pi for the asymmetric bridge close to rupture. The influence of slenderness on the time interval between asymmetric pinch-off events, velocity, destination, and size of the satellite droplet is explored.

Summary: In this study, a high-throughput piezoelectric droplet dispensing technique based on the resonance of the liquid column within the glass capillary was proposed. Experimental and theoretical studies showed that the resonance frequencies of different orders of the liquid column perfectly matched the theoretical value. It was further demonstrated that droplets could be ejected by a driving voltage as low as 1 V when the working frequency was close to the resonant frequency of the piezoelectric ceramic. This ultra-low driving voltage and power consumption make this dispenser compatible with various digital transistor-transistor logic or complementary metal-oxide-semiconductor drive circuits without any power amplifier.
