Summary: In this study, femtosecond laser ablation was used to generate nanoparticles from decagonal quasicrystals in a liquid medium. The structural analysis showed that the nanoparticles retained the phase of the target material. Formation of Al3Ni2 phase was observed in Al70Co20Ni10, while no formation of Al-Ni phase was observed in Al70Co15Cu10Ni5. Optical analysis confirmed the formation of Al2O3 in both cases, with a weak signal of CuO detected in Al70Co15Cu10Ni5. Laser-induced periodic surface structures were also studied in the ablated region of the target's surface.

Summary: A novel method of fabricating large-area, low-cost surface-enhanced Raman spectroscopy (SERS) substrates is introduced, which utilizes laser-induced periodic surface structuring (LIPSS) of crystalline silicon (Si) to achieve densely nanostructured surfaces. The SERS effect is attributed to the electromagnetic field enhancement originating from the nanoscale surface roughness of Si that can be controlled by LSFL and HSFL nature of the structure. The experimental and simulation results show that LSFL and HSFL Si surfaces with a 70 nm thick Ag layer exhibit the strongest SERS effect.

Summary: Laser induced periodic surface structures (LIPSS) were analyzed on steel and copper surfaces in detail. The thermal conductivity differences between the two metals determine the rate of extinguishing of laser-induced temperature modulation. Femtosecond laser radiation sources with different wavelengths were used to inscribe low spatial frequency LIPSS. For steel samples, regular LIPSS were formed for both wavelengths but their regularity decreased with shorter wavelength. For copper samples, LIPSS with lower regularity were formed and even absent in one of the scanning methods at UV wavelength. Numerical analysis based on the 2D heat diffusion equation revealed that temperature modulation decreased considerably faster in copper and at higher modulation frequency.

Summary: This study fabricates femtosecond laser-induced periodic surface structures (LIPSS) with low and high spatial frequencies on a stainless-steel surface simultaneously by varying the wavelength. The results show that the periodicities of both low and high spatial frequency LIPSS can be controlled by the wavelength, and the formation of high spatial frequency LIPSS depends on the primary low spatial frequency LIPSS. These experimental insights are important for understanding and describing the formation of LIPSS.

Summary: This study investigates the laser-induced periodic surface structuring (LIPSS) under cryogenic conditions using a femtosecond fiber laser. The results show that the thermal properties of the substrate and the intensity of the laser beam affect the surface patterns formed.

Summary: This work explores the combination of direct femtosecond laser structuring of metal surfaces and Spatial Atomic Layer Deposition (SALD) of metal oxides as a novel approach to generate colors on different types of metallic objects. The results show that the thickness of the oxide coating can control both the iridescence properties and the final color of the metal surface, while acting as a protective layer. The study suggests that this methodology has the potential to achieve cheap, scalable, and high-throughput processing methods for coloring metallic surfaces.

Summary: Ablative laser processing with ultrashort pulsed laser beams can cause secondary emission of hazardous X-rays. However, the X-ray emission rates during ablative processing of biological tissue materials have not been widely explored. In this study, biological materials were ablated with ultrashort laser pulses and in-situ X-ray dose rate measurements were performed. The results showed the secondary emission of laser-induced X-rays in all the studied biological materials.

Summary: By using a positively charged two-dimensional poly(pyridinium salt) membrane (C2DP) as the graphite electrode skin, the durability problem of graphite electrode can be overcome. The large-area C2DP coating on the graphite electrode alleviates the electrolyte and the ultrathin C2DP with high anion-transport capability prevents cation/solvent co-intercalation into the graphite electrode. The C2DP-covered graphite electrode demonstrates impressive PF6- intercalation durability with high capacity retention and Coulombic efficiencies.

Summary: In this study, two organic-metal photocatalysts, P-L (PtCl2 and PdCl(2)), were proposed. X-ray photoelectron spectroscopy showed that their binding energies match precisely the binding energies of the respective M-(bpy)-Cl-2 complexes. Cyclic voltammetry measurements of the complexes displayed additional reduction potentials upon metal insertion. Light-driven catalysis demonstrated that both compounds are catalytically active, with P-Pt outcompeting P-Pd with a TON of 186 over 48 h in the presence of ascorbic acid (P-Pd: 50). Time-resolved spectroscopy on P-L and P-Pt yields insights into the light-induced intramolecular processes, and the role of different excitation states in the catalytic process.

Summary: A critical point drying (CPD) technique using supercritical CO2 as a cleaning step for graphene field-effect transistors (GFETs) on oxidized Si wafers is reported, which improves the field-effect mobility and reduces impurity doping. The CPD treatment significantly reduces polymeric residues on graphene and effectively removes ambient adsorbates, such as water, thus reducing undesirable p-type doping of GFETs. It is proposed that CPD is a promising technique to restore the intrinsic properties of 2D materials-based electronic, optoelectronic, and photonic devices after microfabrication and storage at ambient conditions.

Summary: In this study, the sliding friction between PMMA colloidal probes and LIPSS on stainless steel were investigated. The results showed a reverse stick-slip mechanism and the morphologies of the probes and steel surfaces were observed using AFM. The friction force was found to be proportional to the normal load and independent of the direction of motion, reaching its maximum with the smaller probe scanning on the LIPSS with the larger periodicity. The friction also decreased with increasing velocity due to the decrease in viscoelastic contact time.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
