Achieving Significantly Boosted Dielectric Energy Density of Polymer Film via Introducing a Bumpy Gold/Polymethylsilsesquioxane Granular Blocking Layer.

Polymer dielectrics are the key materials for pulsed energy storage systems, but their low energy densities greatly restrict the applications in integrated electronic devices. Herein, a unique bumpy granular interlayer consisting of gold nanoparticles (Au NPs) and polymethyksesquioxane (PMSQ) microspheres is introduced into a poly(vinylidene fluoride) (PVDF) film, forming trilayered PVDF-Au/PMSQ-PVDF films. Interestingly, the Au/PMSQ interlayer arouses a dielectric enhancement of 47% and an ultrahigh breakdown strength of 704 MV m, which reaches 153% of pure PVDF.

Experiencing an art education program through immersive virtual reality or iPad: Examining the mediating effects of sense of presence and extraneous cognitive load on enjoyment, attention, and retention.

Sense of presence and extraneous cognitive load (ECL) are the two psychological effects widely employed to explain the cognitive outcomes caused by high-immersive media (e. g., virtual reality).

Do You Feel the Same as I Do? Differences in Virtual Reality Technology Experience and Acceptance Between Elderly Adults and College Students.

Virtual reality (VR) has been widely applied in medical health areas and the entertainment and tourism industries, in which elderly people are a primary target. However, most studies on VR have focused on how people respond to this new technology and its effects on younger generations. Our study explored the differences in VR experience and acceptance between elderly adults and college students.

The Effects of Viewing an Uplifting 360-Degree Video on Emotional Well-Being Among Elderly Adults and College Students Under Immersive Virtual Reality and Smartphone Conditions.

Positive emotions are important for the physical and mental health of elderly adults. Previous research has suggested that the emotion processing mechanisms of elderly adults differ from those of young people. The current study used a mixed-methods approach to explore the emotional impacts of viewing an uplifting 360° videos under immersive (using a virtual reality [VR] headset) and nonimmersive (using a smartphone) conditions on elderly populations and young people.

A transcriptomic study of selenium against liver injury induced by beta-cypermethrin in mice by RNA-seq.

Evidence from biochemical liver function index and histopathology analysis suggested that selenium could effectively repair the liver injury caused by beta-cypermethrin (β-CYP). However, the molecular mechanism of selenium against liver injury induced by β-CYP remains unclear. In the present study, dynamic changes in gene expression profiles before and after the treatment of NaSeO in liver injury mice were analyzed by using RNA sequencing.

The protective effects of selenium-enriched spirulina on the reproductive system of male zebrafish (Danio rerio) exposed to beta-cypermethrin.

Beta-cypermethrin (beta-CYP), which is widely used for the control of indoor and field pests, is a highly lipophilic insecticide with environmental estrogenic effects. Selenium-enriched Spirulina (Se-SP) is a novel natural antioxidant agent with a high nutritional value. This study was aimed at the investigation of the protective effects of Se-SP on the reproductive system of male zebrafish (Danio rerio) exposed to beta-CYP.
