The molecular weight shows great influence on dielectricand energy storage performance of poly(vinylidenefluoride) (PVDF) films and related devices. In this letter,the influences of molecular weight on the dielectric andenergy storage properties of PVDF films were studied. Ithas been found that, under a 1000 kV/cm electric field,the low-molecular-weight PVDF film presents a muchhigher energy storage efficiency as high as 80.10%,nearly three times as much as the high-molecular-weightPVDF film. Moreover, the low-molecular-weight PVDFfilm also shows high resistivity, representing an order ofmagnitude improvement over the high-molecular-weightPVDF film, which is more desirable and promising forhigh performance pulse discharge capacitor application.

Rift Valley fever (RVF) is an acute, febrile zoonotic disease that is caused by the RVF virus (RVFV). RVF is mainly prevalent on the ArabianPeninsula, the African continent, and several islands in the Indian Ocean near southeast Africa. RVFV has been classified by the WorldOrganisation for Animal Health (OIE) as a category A pathogen. To avoid biological safety concerns associated with use of the pathogen inRVFV neutralization assays, the present study investigated and established an RVFV pseudovirus-based neutralization assay. This study usedthe human immunodeficiency virus (HIV) lentiviral packaging system and RVFV structural proteins to successfully construct RVFVpseudoviruses. Electron microscopy observation and western blotting indicated that the size, structure, and shape of the packagedpseudoviruses were notably similar to those of HIV lentiviral vectors. Infection inhibition assay results showed that an antibody against RVFVinhibited the infective ability of the RVFV pseudoviruses, and an antibody neutralization assay for RVFV detection was then established. Thisstudy has successfully established a neutralization assay based on RVFV pseudoviruses and demonstrated that this method can be used toeffectively evaluate antibody neutralization.
