Special oleophobic and hydrophilic surfaces: approaches, mechanisms, and applications

Abstract: An oleophobic and hydrophilic surface is a surface that is more wettable to water than to oil. In recent years, this novel surface has attracted significant attention since it is highly desirable in many important applications such as long-term anti-fogging, detergent-free cleaning, and oil and water separation. In this study, we focused on recent advances in oleophobic and hydrophilic surfaces. We briefly summarized three approaches, including simultaneously oleophobic/hydrophilic behavior, oleophobic/hydrophobic to hydrophilic switching behavior, and hydrophilic/underwater superoleophobic behavior, to achieve this surface. Moreover, we discussed the underlying mechanisms and the potential applications of this surface have also been introduced.

Effect of grain size on the energy storage properties of (Ba0.4Sr0.6)TiO3 paraelectric ceramics

Abstract: (Ba 0.4 Sr 0.6 )TiO 3 (BST) ceramics with various grain sizes (0.5–5.6 μm) were prepared by conventional solid state reaction methods. The effect of grain size on the energy storage properties of BST ceramics ( T c ≈ −65 °C) was investigated. With decreasing grain sizes, a clear tendency toward the diffuse phase transition was observed and the dielectric nonlinearity was reduced gradually, which can be explained by the Devonshire's phenomenological theory (from the viewpoint of intrinsic polarization). Based on the multi-polarization mechanism model, the relationship between the polarization behavior of polar nano-regions (the extrinsic nonlinear polarization mechanisms) and grain size was studied. The variation of the grain boundary density was thought to play an important role on the improvement of dielectric breakdown strength, account for the enhanced energy density, which was confirmed by the complex impedance spectroscopy analysis based on a double-layered dielectric model.

Effects of misinformation on COVID-19 individual responses and recommendations for resilience of disastrous consequences of misinformation

Abstract: The proliferation of misinformation on social media platforms is faster than the spread of Corona Virus Diseases (COVID-19) and it can generate hefty deleterious consequences on health amid a disaster like COVID-19. Drawing upon research on the stimulus-response theory (hypodermic needle theory) and the resilience theory, this study tested a conceptual framework considering general misinformation belief, conspiracy belief, and religious misinformation belief as the stimulus; and credibility evaluations as resilience strategy; and their effects on COVID-19 individual responses. Using a self-administered online survey during the COVID-19 pandemic, the study obtained 483 useable responses and after test, finds that all-inclusive, the propagation of misinformation on social media undermines the COVID-19 individual responses. Particularly, credibility evaluation of misinformation strongly predicts the COVID-19 individual responses with positive influences and religious misinformation beliefs as well as conspiracy beliefs and general misinformation beliefs come next and influence negatively. The findings and general recommendations will help the public, in general, to be cautious about misinformation, and the respective authority of a country, in particular, for initiating proper safety measures about disastrous misinformation to protect the public health from being exploited.
