Summary: This study investigates the electrostrictive and structural properties of P(VDF-HFP) nanofibers modified with conductive polymer polyaniline (PANI). The composite nanofibers showed uniform fibers without bead formation, with decreased water contact angle and increased dielectric properties and electromechanical response as the PANI content increased. The results suggest that P(VDF-HFP)/PANI composite nanofibers may offer a promising route for electrostrictive applications in actuation, MEMS, and sensors.

Summary: This study focuses on the nonlinear creep characteristics of extruded Poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) at temperatures between 40 ℃ and 80 ℃, and tensile stress levels of 5 MPa to 12.5 MPa. The results indicate that nonlinearity occurs at around 60 ℃, and relaxation begins at 100 ℃ above the measured glass transition temperature of PVDF-HFP. The Findley power law model is used to develop a generalized temperature-and stress-dependent model, which effectively describes the nonlinear creep behavior of the polymer under different temperature and stress conditions.

Summary: In this study, Fourier self-deconvolution (FSD) of the infrared spectrum was used to quantify the relative fractions of the electro-active (EA) crystal phases in poly(vinylidene fluoride) (PVDF). The results showed that only polar crystal phases were present in the samples prepared by electrospinning and electrospraying, and no non-polar alpha phase crystals were found. The application of FSD allowed the determination of the absolute content of the polar beta and gamma phases, showing that the gamma phase dominated over the beta phase in both electrospun and electrosprayed materials.

Summary: This study explores a rapid, efficient, green and eco-friendly approach for the preparation of reduced graphene oxide (rGO) using Plectranthus amboinicus leaves extract (PAE). The physical and chemical properties of rGO are studied, and it is found that the PAE can significantly remove oxygen-containing functional groups from GO, resulting in a higher level of disorder and a decrease in the average size of the sp(2) domain in rGO. The electrochemical studies also show improved performance of rGO.

Summary: Semantic segmentation of Martian terrain is crucial for rover route planning and navigation on Mars. Existing methods perform poorly in the unstructured Martian environment. Therefore, a novel hybrid attention semantic segmentation (HASS) network is proposed, which includes a global intra-class attention branch, a local inter-class attention branch, and a representation merging module. In addition, a panorama semantic segmentation dataset named MarsScapes is established, providing fine-grained annotations for eight semantic categories. Extensive experiments on MarsScapes and the public AI4Mars datasets demonstrate the superiority of the proposed method.

Summary: Solar cells based on three-dimensional perovskites have high photoconversion efficiency but suffer from surface defects and inadequate interactions between components. In contrast, two-dimensional perovskites have better stability but lower efficiency. Recent research has shown that surface passivation of 3D perovskites with 2D perovskites can improve the stability without compromising efficiency. This review discusses the advances in surface modification of 3D perovskites using 2D perovskites, including crystal structures, photoelectric properties, and passivation strategies.
