Summary: The study investigates the incorporation of metal ions in dielectric layers by means of electric field assisted film dissolution. Simulation results show that metal ions dope the dielectric layer until they reach the glass matrix, with potential applications in optical and photonic devices. Experimentally, Ag doping of SiO2 layers deposited on soda-lime and borosilicate glasses confirms the model trends in ion migration.

Summary: This study investigates the process of glass poling and electric field assisted dissolution of metal films on coated glass substrates. The results show that the metal film is dissolved and partially incorporated in the dielectric layer and glass substrate. Furthermore, it is found that the field-assisted dissolution strongly depends on the dielectric layer material and its ion incorporation during pre-heating. The process dynamics are confirmed by numerical simulations and electrical current measurements. Overall, this study broadens the potential of glass poling and electric field assisted dissolution in photonics applications.

Summary: This study explores a new method to improve the contact between conductive nanoparticles and the cell membrane using the effects of electric pulses. The results demonstrate that delivering an electric field prior to electroporation pulses can increase the accumulation of nanoparticles around the cell membrane, reducing the need for long incubations between cells and nanoparticles to observe enhanced electroporation.

Summary: The study reveals that at the glass-water interface, ion exchange can occur as Na+ ions leave their initial positions and are replaced by H+ ions or another diffused Na+ ions. The high affinity between water and Na+ ions leads to the release of Na+ ions into the bulk water. Additionally, oxygen-bearing functional groups can form through protonation of NBO sites or filling defects with OH- from water molecules.

Summary: In this work, the possible mechanisms of photodarkening in Pr3+ singly doped and Pr3+/Ce3+ co-doped silicate glasses and fibers have been revealed, and the role of Ce3+ in increasing radiation resistance in Pr3+-doped silicate glasses and fibers has been studied. The results show that co-doping Ce3+ can efficiently suppress the darkening induced by both X-ray and 488-nm laser radiations without influencing the luminescence behavior of Pr3+ ions. This study demonstrates the promising potential of Pr3+/Ce3+ co-doped silicate glasses for visible lasing applications.

Summary: This study conducted an electric field-assisted ion exchange process on an innovative glass and measured various parameters to analyze their correlation with processing conditions. The results showed that the glass had a high propensity for chemical strengthening, and the application of an electric field had a beneficial effect on the penetration of potassium ions.

Summary: This study demonstrates the feasibility of using the field-Assisted sintering technique (FAST) for sintering larger rods of a biomedical Ti-15Mo alloy. By implementing an adequate die arrangement, rods of nearly 80 mm in length and 15 mm in diameter were sintered in less than 30 min with a densification above 95%. However, the technique's inherent pressure and temperature distributions may result in microstructural features.

Summary: This study focuses on the preparation of Tm3+/Ho3+ co-doped germanate glass and the successful fabrication of a broadband high-gain multimaterial fiber. The fiber is used for high-repetition-rate mode-locked fiber lasers. An all-fiber-integrated passively mode-locked fiber laser with high frequency and broadband output is demonstrated.

Summary: The surface activated bonding (SAB) technique allows room temperature bonding of metals by forming metal bonds between clean and reactive surfaces. However, re-adsorption on the activated surface decreases the bonding quality, limiting its applicability for electronics packaging. This study proposes and demonstrates the prolongation of surface activation effect for room temperature bonding of Au using a self-assembled monolayer (SAM) protection. The surface analysis shows that the clean and activated Au surface is protected from re-adsorption by SAM, allowing for time-independent bonding of Au at room temperature.

Summary: The study revealed that the presence of TiO2 in the glass caused changes in the structure of boron and silicon, affecting the crystalline properties of the glass. As the TiO2 content increased, the glass stability parameters increased, while the activation energy for crystallization decreased.
