Summary: An innovative approach to fabricate lightweight, highly sensitive 3D conductive nanofiber sponges for pressure sensors was reported. The 3D sponges were prepared by self-assembly of electrospun carbon nanofibers/aminated Fe3O4 and reduced graphene oxide (rGO) nanosheets. The orientation and distribution of the graphene nanosheets were further regulated by an external magnetic field to improve the sponge's performance.

Summary: This work presents a method for fabricating 3D helical plasmonic nanostructures from 2D plasmene nanosheets. By using a micro-spatula-based strategy inspired by the chocolate curls-making process, the plasmene nanosheets can be selectively scraped to free space, resulting in the spontaneous folding of the nanosheets into various complex helical nanostructures with controlled dimensions. This versatile fabrication route combines both bottom-up and top-down approaches and has potential applications in next-generation flexible nanophotonic devices.

Summary: The power-sensitive photo-thermal tuning (PTT) behavior of graphene oxide (GO) integrated on the top surface of silicon nitride (SiN) waveguides is experimentally investigated. The thresholds for reversible and permanent GO reduction are measured for SiN waveguide coating with monolayer GO. Three reduction stages are identified based on the reversibility of the reduction process. The study confirms that the PTT is primarily determined by the average input power, regardless of the type of laser used.

Summary: Graphene oxide (GO) films integrated on silicon nitride (Si3N4) waveguides through a solution-based method enhance the spectral broadening and self-phase modulation (SPM) effect. The GO-coated waveguides show significantly improved nonlinear performance compared to the uncoated waveguide, resulting in a broadening factor of up to 3.4 and an improvement in the waveguide nonlinear parameter by a factor of up to 18.4. The high Kerr nonlinearity of GO contributes to the enhancement of SPM in Si3N4 waveguides.

Summary: In this study, we generated cylindrical vector pulsed beams by using a c-cut Tm:CaYAlO4 crystal and SESAM in a folded six-mirror cavity. By adjusting the distance between the curved cavity mirror (M4) and the SESAM, both radially polarized beam and azimuthally polarized beam were generated around 1962 nm and the two vectorial modes could be freely switched in the resonator. When the pump power was increased to 7 W, stable radially polarized Q-switched mode-locked (QML) cylindrical vector beams were obtained with an output power of 55 mW, sub-pulse repetition rate of 120.42 MHz, pulse duration of -0.5 ns, and the beam quality factor M2 of -2.9. To our knowledge, this is the first report of radially and azimuthally polarized beams in the 2 μm wavelength solid-state resonator.

Summary: We demonstrate enhanced self-phase modulation (SPM) in silicon nitride (Si3N4) waveguides integrated with two-dimensional graphene oxide (GO) films. The use of a solution-based, transfer-free coating method allows precise control of the film thickness. The hybrid waveguides show significantly improved spectral broadening due to the high Kerr nonlinearity of GO, achieving a broadening factor of up to 3.4. The experimental results show an improvement in the waveguide nonlinear parameter by a factor of up to 18.4 and a Kerr coefficient (n(2)) of GO that is about 5 orders of magnitude higher than Si3N4. Theoretical analysis is provided for the influence of GO film length, coating position, and saturable absorption on the SPM performance.

A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
