“…In acrylic painting, regardless of style and mood, it can be enhanced by a variety of techniques, and because acrylic is water-soluble, many special effects can be designed. It is different from other painting materials, such as oil painting and watercolor [7], which are mostly derived from nature, or some mineral materials, plant materials. Acrylic material is a new type of painting material derived from the development of science and technology, ideas, and technological innovation.…”

Bi4Ti3O12 ferroelectric nanomaterials are mainly used in the manufacture of biosensors, biomedical imaging reagents, or other biomedical applications. Due to the different arrangements of Bi4Ti3O12 ferroelectric nanoparticles, complex nanofibers with specific geometries can be obtained. In this paper, Bi4Ti3O12 ferroelectric nanomaterials were used to study the volatilization state of the acrylic paint used in the coating process. This article explains that some Bi4Ti3O12 nanoparticles were difficult to be dispersed in spinning solution, which made the preparation of composite fibers difficult. Therefore, these issues need further research and resolution. This work proposes to selectively reduce the use of graphene oxide by using an environmentally friendly water solvent to prepare water-reduced graphene oxide (rGO) and then inject octadecylamine into the selectively reduced graphene oxide to prepare octadecylamine-grafted reduced graphene oxide (rG-ODA). The experimental results in this paper showed that through seeding and reduction, functional groups such as carboxyl groups and epoxy groups on the surface of graphene oxide disappeared, and graphene oxide was well reduced. The presence of oxygen-containing functional groups increased the distance between the graphitic layers to 0.713 nm. GS-EDA had a characteristic diffraction peak close to 2θ = 24.3°, indicating that GO was effectively reduced after inoculation reduction.

“…In recent years, lead titanate (PT) based ceramics become one of the most studied and used ferroelectric materials in both scientific and industrial communities due to its high Curie temperature ( T c ) and low dielectric constant 24,25 , which make PT based ceramic to be a valuable research object 26–30 . In this work, lanthanum modified lead titanate ceramics (Pb 1− x La x )Ti 1− x /4 O 3 (PLT100 x , x = 0.20, 0.24, 0.28, and 0.32, abbreviated as PLT20, PLT24, PLT28 and PLT32 respectively) ceramics are prepared and studied.…”

The unique properties and great variety of relaxer ferroelectrics make them highly attractive in energy-storage and solid-state refrigeration technologies. In this work, lanthanum modified lead titanate ceramics are prepared and studied. The giant electrocaloric effect in lanthanum modified lead titanate ceramics is revealed for the first time. Large refrigeration efficiency (27.4) and high adiabatic temperature change (1.67 K) are achieved by indirect analysis. Direct measurements of electrocaloric effect show that reversible adiabatic temperature change is also about 1.67 K, which exceeds many electrocaloric effect values in current direct measured electrocaloric studies. Both theoretical calculated and direct measured electrocaloric effects are in good agreements in high temperatures. Temperature and electric field related energy storage properties are also analyzed, maximum energy-storage density and energy-storage efficiency are about 0.31 J/cm3 and 91.2%, respectively.

In this study, we report the influences of distilled water and ammonium fluoride (NH4F) on morphology of pores in honeycomb-like titanium dioxide (TiO2) nanotube arrays. We observed the structure and arrangement of pores in the TiO2 nanotube arrays based on scanning electron microscopy images and analyzed the spatial distribution of the pores using fast Fourier transform and Voronoi diagram. We studied the individual pore properties including pore diameter, wall thickness, and interpore distance and found that locally connected ordering defects decreased with increasing distilled water concentration. Furthermore, we found that the optimum conditions of well-ordered hexagonal pore arrangement were 2 and 10 vol% distilled water with 0.2 and 0.4 wt% NH4F, respectively. Throughout this study, we provide a better understanding about the roles of distilled water and NH4F in forming well-ordered nanoscale pore structure with less ordering defects in the honeycomb-like TiO2 nanotube arrays.
