Summary: This study investigated the biocompatibility, biological performances, and cell uptake efficiency of AuNP in Wharton's jelly mesenchymal stem cells and a rat model. Various concentrations of AuNP were prepared and characterized. In vitro examinations showed that treatment with 1.25 and 2.5 ppm AuNP improved viability, CXCR4 expression, migration distance, and reduced apoptotic-related protein expression in Wharton's jelly MSCs. AuNP-Col was taken up by cells via clathrin-mediated endocytosis and the vacuolar-type H+-ATPase pathway. In vivo examinations demonstrated that 2.5 ppm AuNP attenuated foreign body responses and had better retention efficacy in tissue integrity. Overall, AuNP shows promise as a biosafe nanodrug delivery system for regenerative medicine with Wharton's jelly MSCs.

Summary: Functionalization of nanomaterial surfaces is crucial for improving stability, tuning reactivity, and introducing specific properties. Mapping functional groups at nanometer scale is challenging, especially for organic groups and non-planar objects like nanoparticles. A strategy using chemically-modified gold colloids to map amine groups on silica particle surfaces is presented, showing correlation between spatial distribution of gold colloids and chemical state of silica particles as revealed by X-ray photoelectron spectroscopy. The strategy's potential for mapping organic groups at nanomaterial interfaces and its implications for biofunctional nano-objects are discussed.

Summary: The absorption of light in the near-infrared region by Au-hyperdoped Si is observed. Current silicon photodetectors in this range have low efficiency. Through laser hyperdoping of thin amorphous Si films, we characterize the composition, chemical, structural, and IR spectroscopic properties of hyperdoped Si with gold and demonstrate several promising regimes. It is found that the optimal efficiency of impurity-hyperdoped Si materials has not been achieved yet.

Summary: This study investigated the treatment efficiency of Cu-Cy based X-PDT under clinical conditions, using a clinical linear accelerator and deep-seated tumor models. The results showed that Cu-Cy nanoparticles had low toxicity in cells at a low concentration, and Cu-Cy mediated X-PDT can inhibit cell proliferation and migration in a dose-dependent manner. Furthermore, this therapy inhibited the growth of deep-seated tumors in mice and rabbits without obvious toxicities. These findings suggest that Cu-Cy NPs have a promising clinical application prospect in X-PDT.

Summary: Free-electron lasers (FELs) are advanced light sources that can produce high-brightness, femtosecond pulses in extreme-ultraviolet, soft and hard X-ray spectral ranges. The development of time-resolved experiments using FEL pulses with tunable colors at specific electronic resonances is the next step in ultrafast X-ray science. The AC/DC optical device at the FERMI FEL facility in Trieste, Italy splits the incoming FEL pulse using a grazing incidence flat mirror, preserves its spectral and temporal properties, and delays one of the split pulses. It also allows for independent control of FEL pulse fluence using solid-state filters.

Summary: Depositional and erosional processes, subsidence and sea-level changes have significantly impacted the coastal landscape of northern Adriatic lagoons. The retrieval and analysis of six metal swords from Marano Lagoon, combined with the study of the coastal paleo-environment, revealed the historical importance of the area and the significant morphological changes that have occurred there. The data also indicate that Marano Lagoon served as a major hub in the northern Adriatic during the Late Middle Ages and Early Modern times, connecting inland Europe with the Mediterranean Sea. Furthermore, the research highlights the onset of coastal erosion and its possible causes.

Summary: Secondary Zn-based batteries are a promising alternative to Li batteries for stationary storage, but their commercialization is hindered by issues such as anode shape-change and passivation. This study investigates the use of mildly acidic electrolytes to limit the unstable growth of Zn, with a focus on the impact of specific quaternary ammonium salts as electrolyte additives. The results show that TBAB is the most effective additive for low-current density operation, while additive-free electrolyte performs better at high current densities, consistent with previous findings for alkaline electrolytes.

Summary: The characterisation of lime mortars is crucial for the conservation and repair of ancient buildings. The pore structure, influenced by manufacturing processes, recipes, and technical expedients, plays a significant role in the strength and durability of mortars. Fermenting organic matter in water and adding it to lime mixture has shown promising potential for improving workability and mechanical performance. The use of high-resolution synchrotron radiation computed microtomography (SR-mu-CT) proves to be an effective tool for studying the contribution of organically fermented water in lime mortars and understanding the impact on pore structure and mechanical properties.
