Summary: High entropy alloy (HEA) thin-film coatings have excellent physical, mechanical, and electrochemical properties, making them popular in surface engineering applications. The deposition process, particularly the energy of the impacting species, plays a crucial role in the density and microstructure of the coatings. RF magnetron sputtering and HiPIMS techniques were used in this study to deposit Al0.5CoCrFeNi2Ti0.5 HEA thin-film coatings, resulting in improved surface morphology and corrosion resistance. The study demonstrates that these techniques offer better control over the properties of the thin-film coatings, enhancing their potential use in extreme environments.

Summary: This study reports the material properties of gallium-doped zinc oxide grown from a high impulse magnetron sputtering system (HiPIMS) and compares them to those of radio frequency (RF) sputtering deposition. The results show that HiPIMS and RF processes yield similar outcomes under the same average power conditions. RF depositions exhibit slightly higher band gap and deposition rate, as well as lower resistivity and optical absorption coefficient. Both methods show that band gaps and grain size increase with deposition power.

Summary: Silicon nitride-based electrodes (SiNx) have been proposed as candidates for high-capacity transparent anode electrodes, but their low electrical conductivity limits their application in thin film batteries. To overcome this, we introduced uniformly dispersed Ag nanoparticles in SiNx thin film to enhance electrochemical properties without affecting transmittance. The addition of Ag increased the capacity of the thin-film battery and allowed for higher C rates, while maintaining optical transmittance over 60% in the visible range.

Summary: This work investigated the influences of mirror-field and closed-field magnetic field configurations on plasma parameters and ion flux dynamics in dual magnetron reactive high power impulse magnetron sputtering with Al targets in Ar/O-2 mixture. The study found that the plasma compositions were similar in both configurations, but the closed-field discharge had higher electron density and lower plasma potential compared to the mirror-field discharge. The ion energy distribution functions showed different peak energies and ion fluxes between the two configurations, with the mirror-field discharge peaking at the end of the pulse and the closed-field configuration reaching peak fluxes 10 µs after pulse termination.

Summary: Tethered-liquid perfluorocarbon (TLP) coatings have shown potential in reducing blood adhesion and delaying thrombosis on blood-contacting medical devices. In this study, a vapor phase silanization reaction was used to create tethered-perfluorocarbon (TP) layers with large bumpy aggregates on top of a uniform coating. The vapor phase method was found to be effective in reproducibly creating slippery coatings with low water sliding angles. The TP layer retained perfluorinated lubricants even under high shear rates and showed reduced fibrin adhesion from human whole blood compared to control surfaces.

Summary: High entropy alloys (HEAs) are a new class of materials with high strength, high corrosion and oxidation resistance, and superb thermal stability. In this study, AlCrFeCoNiCu0.5 HEA thin films were fabricated using cathodic arc deposition, and the growth mechanisms and microstructures of the films were investigated by varying arc and duct currents. The crystallography of the films was analyzed using X-ray diffraction (XRD), and the film chemistry and microstructure of the film-substrate interphase were comprehensively studied using transmission electron microscopy (TEM). The results show that the grain size, hardness, and surface roughness of the HEA thin films can be effectively controlled. This study has important implications for the industrial-scale fabrication of HEA thin films using cathodic arc deposition.

Summary: Strategies are needed to promote rapid formation of functional endothelium in synthetic vascular conduits. In this study, silk biomaterials were biofunctionalized with recombinantly expressed domain V of human perlecan (rDV) to promote endothelial cell interactions and functional endothelium formation. The immobilization of rDV on silk using plasma immersion ion implantation (PIII) was assessed for its amount, orientation, and bio-functionality. rDV immobilized on PIII-treated silk supported rapid endothelial cell adhesion, spreading, and proliferation to form functional endothelium. This suggests the potential of rDV-PIII-silk as a biomimetic vascular graft material.

Summary: In this study, polydimethyl glutarimide (PMGI) layers were modified to introduce free radical covalent binding sites. Horseradish peroxidase (HRP) enzyme was successfully immobilized on the treated PMGI, and the treated PMGI was incorporated as a gate dielectric layer in a three-terminal electrolyte-gated device. The presence of HRP on the plasma-modified PMGI gate dielectric layer altered the device characteristics and allowed for readout detection.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
