Summary: Compositionally graded samples of Ti-xNb-7Zr-yO alloys with various chemical compositions were prepared and studied for potential biomedical use. The elastic constants of each sample were determined, showing a dependence on the volume fraction of niobium and oxygen. The lowest elastic modulus was observed near the stability limit between β matrix and α'' martensitic phase, while the presence of isothermal ω particles led to the highest elastic constants.

Summary: This study investigates the processing and properties of Ti-Cu-Nb alloys obtained via powder metallurgy. The studied alloys have a lamellar microstructure, which is refined by the incremental addition of Cu+Nb and a eutectoid substructure is formed for sufficiently high contents of Cu. The resistance to plastic deformation increases monotonically due to the microstructural changes, while the ductility initially increases for small additions of Cu+Nb and subsequently decreases due to the impact of the residual pores.

Summary: Powder metallurgy Cu-30Fe alloy was prepared using mechanical alloying, pressureless sintering, and rolling processes. The rolling process affected the alloy microstructure and physical properties. The Fe particles became elongated and changed shape, while the Cu grains became elongated and refined. The coordinated deformation of the Cu and Fe phases resulted in finer Cu grains near the Fe particles. After annealing, the cold-rolled Cu-30Fe alloy achieved a good combination of mechanical and functional properties.

Summary: In this study, the addition of cheap alloying elements (Cu and Fe) in Ti alloys was analyzed to produce low-cost ternary Ti-Cu-Fe alloys using powder metallurgy. The results showed that the compressibility of the powder blends decreased with the increase of alloying elements, but similar relative density values could still be achieved. The addition of Cu and Fe resulted in the formation of alloys with a lamellar microstructure, and the specific chemistry of the alloy determined the features of the microstructure and the deformation and failure mechanisms of the sintered ternary Ti-xCu-xFe alloys.

Summary: Reducing the manufacturing cost of titanium and developing new alloys are crucial for maximizing the benefits of titanium in industrial applications. The addition of isomorphous and eutectoid beta stabilizers has a significant effect on the manufacturability and mechanical response of titanium.

Summary: This study investigated the addition of eutectoid (iron) and isomorphous (niobium) beta stabilisers to create ternary alpha + beta titanium alloys, which is a gap in the existing literature focused on metastable or stable beta Ti-Fe-Nb alloys. The incremental addition of iron and niobium improves the density, reduces compressibility, enhances densification, and refines the microstructure of the alloys. The resulting sintered Ti-Fe-Nb alloys exhibit increased load bearing capability and comparable mechanical properties to heavily alloyed cast Ti-Fe-Nb alloys.

Summary: This study investigated the addition of a non-hydride forming element in the multicomponent Ti-V-Nb-M system using the CALPHAD approach. Cr was selected as the fourth alloying element, and (TiVNb)(100-x)Cr-x alloys were synthesized and found to absorb hydrogen at room temperature without activation treatment. Increasing the Cr content in the alloys resulted in higher equilibrium pressures, indicating tunable hydrogen storage properties could be achieved.

Summary: MXenes have emerged as promising reinforcements in polymer-based nanocomposites due to their combined mechanical and electronic properties with functional groups. The presence of these functional groups significantly affects the electronic properties, dispersion, and interfacial bonding of MXenes in composites. Through Density Functional Theory (DFT) simulations, it was found that the cohesion at the interface follows the order O > F > OH, thanks to the formation of hydrogen bonds and lower charge transfer. This allows for the prediction of conductive PE-MXene composites for applications such as Electromagnetic Interference Shielding (EMI) or artificial muscles.

Summary: In this study, the general features of monoclinic (001) NaTaO3/BaBiO3 heterojunctions were theoretically investigated, exploring the influence of interface creation on their physicochemical properties. The results showed that a superlattice with 24 wt.% of BaBiO3 exhibited the desired electronic structure for photocatalytic reactions, with an intermediate band gap and highly dispersive energy levels. Increasing the number of BaBiO3 layers led to a semiconductor-to-metal transition and the formation of a high-mobility two-dimensional electron gas (2DEG) at the interface. This research highlights the importance of such nanojunctions for both photocatalysis and nanoelectronics applications.

The CALPHAD method was used to design alloys with a body centered cubic structures. Hydrogen absorption/desorption cycles were performed for two alloys showing promising results since the maximum capacity of the alloys has been maintained despite a reduction in absorption kinetics.

Summary: The aim of this study was to investigate the influence of a RuO2 support on the activity of Pd nanoparticles during formic acid oxidation, comparing it with Pd/C. Contrary to previous reports on enhancing effects of RuO2, our findings reveal a negative impact of the RuO2 support on the activity of Pd nanoparticles for formic acid oxidation. The formation of CO2 at low potentials and the absence of adsorbed CO signals suggest that the oxidation of formic acid on Pd/RuO2 and Pd/C occurs through a direct pathway without significant contribution from a bifunctional mechanism involving OH species on the oxide support surface. The detrimental effect of the RuO2 support on activity is likely a result of metal-support interactions altering the electronic properties of Pd.

Summary: Novel high-entropy alloys (HEAs) of the Ti(30-x)VCrNb(x) (x = 0, 5, 10, 15, and 20 at%) system were designed, synthesized, and characterized. The microstructural features were investigated by XRD, SEM, and EDS. The corrosion behavior was evaluated in 3.5 wt% sodium chloride (NaCl) solution of pH 5 at 25 degrees C by potentiody-namic polarization and electrochemical impedance spectroscopy (EIS). The investigated HEAs exhibited a single-phase BCC solid solution with dendritic microstructures. The polarization curves showed the Ti10V35Cr35Nb20 (Nb20) HEA exhibited the best corrosion resistance with the lowest corrosion current density (2.24 mu A/cm2) and corrosion rate (1.15 x 10-2 mm/yr). The interpretation of an equivalent electric circuit (EEC) suggested the formation of a stable passive oxide film on the HEAs, as indicated by good capacitive behavior and high impedance values (>104 omega cm2) at low frequencies and phase angles close to -80 degrees. This study demonstrated that an appropriate Nb content can stabilize the BCC phase and significantly enhance the corrosion resistance of the HEAs.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
