Summary: CuI thin films were deposited with controlled morphology, structure, and defect nature in different Ar atmospheres. Band gap tailoring was achieved by controlling the plasma ion kinetic energy. Variation in Ar pressure allowed control over the nature of vacancies. Addition of Ar resulted in preferential scattering and energy losses of Cu ions in the plasma.

Summary: Samarium doped ceria thin films were successfully deposited on Si (100) substrates at 500 and 600 degrees C using Pulsed Laser Deposition. X-ray Diffraction confirmed the presence of Samarium Doped Cerium Oxide crystalline compound in the films. Atomic Force Microscopy and Scanning Electron Microscopy revealed high quality films with low roughness, especially for the sample deposited at 600 degrees C. X-ray Photoelectron Spectroscopy showed an increased proportion of Ce3+ in the deposited films compared to the target. Spectroscopic Ellipsometry analysis calculated a refractive index under 2.2 in the visible and near-infrared domain. Nanoindentation tribometric measurements indicated a decrease in elasticity modulus and hardness with increasing substrate temperature. These films show potential as electrolyte materials for new generation electrochemical devices.

Summary: Molybdenum oxide is a material with high bandgap, work function, and other interesting properties. Using Pulsed Laser Deposition, researchers were able to deposit high transparency MoO3 layers from stoichiometric MoO3 and metal Mo targets at different temperatures and oxygen pressures. Optical properties were accurately tracked using Photothermal Deflection Spectroscopy and Spectral Ellipsometry, while crystallinity and surface morphology were monitored using X-ray diffraction and Scanning Electron Microscopy. Increasing temperature led to smoother, denser layers, narrowing bandgap, and increased sub-gap absorption, with crystallization occurring above 400 degrees C. Sub-gap absorption around 1000 nm depended on temperature and weakly on oxygen pressure.

Summary: In this study, Co2FeAl (CFA) thin films grown on MgO(001) substrates by pulsed laser deposition (PLD) were investigated for their structural, magnetic, and transport properties. The crystal structure of the CFA thin films changed from disordered A2 to partly ordered B2 as the substrate temperature increased. Both the saturation magnetization and coercive field were enhanced with increasing temperature. Unlike CFA thin films prepared by magnetron sputtering, all the films exhibited a local minimum in longitudinal resistivity near 20 K, which was weakened with improved structure ordering. The anomalous Hall effect in the CFA thin films was dominated by an intrinsic mechanism, and the scattering-independent intrinsic parameter was enhanced with the improvement of crystal structure.

Summary: This paper develops efficient and simplified models for thermal distribution, melt pool dimensions, and controlled phase change in laser additive manufacturing of ceramic materials. The study shows that powder particles have higher thermal distribution due to voids in the powder layer. The presence of voids increases the surface absorption coefficient, which influences the laser beam's behavior. The relationship between laser power and melt pool dimensions is direct, while scanning speed has an inverse relationship. The results obtained from analytical simulations, experimental investigations, and numerical simulations are in good agreement within a range of 4%-8%.

Summary: There is a growing interest in organic photovoltaic (OPV) cells due to their properties and compatibility with various substrates. However, their efficiencies are low compared to silicon cells, and improvements are being sought through electrode nanostructuring, synthesis of new materials, and use of additives. In this study, the behavior of a common organic bulk heterojunction was examined when deposited on different substrates and with/without an additive. The results showed that the morphology of the films can be modified and their roughness decreased with the addition of a small quantity of additive. Micro-patterning of the electrode also increased the absorption of the photovoltaic structures.

Summary: In this study, L-Cysteine-coated magnetic iron oxide nanoparticles loaded with doxorubicin were synthesized and extensively characterized. The binding of doxorubicin to L-Cysteine was confirmed, and the internalization of the nanoparticles delivering doxorubicin was observed in melanoma cells. The nanoparticles also modulated cell signaling pathway activity, induced cell cycle arrest and apoptosis, and exhibited pH-dependent drug release. These results demonstrate the potential of the nanoparticles as efficient drug delivery vehicles in melanoma therapy.

Summary: A novel analytical formalism based on the Quantum heat transport equation is proposed to describe the interaction between femtosecond/picosecond laser pulses and DNA. The formalism generates solutions based on inputs such as voltage, laser beam intensity, and laser-DNA interaction time. Thermal waves induced inside irradiated DNA are accounted for. Analytical simulations show that the optimal regime of laser-DNA interaction occurs when a potential carrier generated at the interface is equal to 3.5 x 10-3 eV. It should be noted that the formalism breaks down if the potential carrier generated at the interface is less than 10-2 eV. Additionally, for pulse durations less than 1 ps, the spatial-temporal distribution of the laser beam plays a crucial role in defining the shape and magnitude of the thermal distribution within the irradiated DNA strands.

Summary: Nanocomposite films based on macrocyclic compounds (ZnPc and TPyP) and metal oxide nanoparticles (ZnO or CuO) were prepared by MAPLE, and the effect of metal oxide addition on the properties of the films was evaluated. The presence of metal oxide nanoparticles influenced the infrared and UV-Vis spectra, as well as the photoluminescence spectra of the films. The morphology of the composite films showed agglomerated particles, but did not significantly affect the roughness. The electrical parameters of the structures based on the nanocomposite films were improved only for films with a certain type and optimum amount of metal oxide nanoparticles.

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.
