Pyrite (FeS2) is an important semiconductor material which shows various excellent optical and electrical properties and extensive applied prospect as a new-type, photoelectrical functional materials. In this study, a low cost and efficient simple hydrothermal two-step synthetic method was given to obtain FeS2 microspheres with 2-3 μm in diameter. The obtained products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and ultraviolet and visible spectrophotometer (UV-Vis). XRD showed that the synthetic sample consisted of two crystal structures of FeS2, pyrite and marcasite. SEM observation indicated that FeS2 microspheres were well crystallized and had good uniformity. UV-Vis spectrum had a strong optical absorption in the region of 200-400 nm wave length. The reaction temperature had an impact on the size of FeS2 microspheres. A possible mechanism for the size of the FeS2 microspheres generated at high temperature is smaller than that at low temperature is discussed.

In this paper, the magnetically controlled characteristic and shape variation mechanism magnetic shape memory alloys (MSMA) sample are studied through the servo valve actuator based on the MSMA. The MSMA is a new type of functional materials, which has huge driving force and large controllability displacement. The kind of actuator is designed by differential mode of MSMA, employing bias coils to generate biasing magnetic field and applying field coils to provide magnetic field which is controllable. The relationship between displacement of the new actuator and time is got by numerical simulation using Maxwell software. Finally, motivated by the simulation results, the rationality of structural design of the new type of actuator is validated.

Compared to liquid electrolytes, lithium solid-state electrolytes have received increased attention in the field of all-solid-state lithium ion batteries due to safety requirements and higher energy density. However, solid-state electrolytes face many challenges, including lower ionic conductivity, complex interfaces, and unstable physical or electrochemical properties. One of the most effective strategies is to find a new type of lithium solid-state electrolyte with improved properties. Traditional trial and error methods require resources and time to verify the new solid-state electrolytes. Recently, new lithium solid-state electrolytes were predicted through machine learning (ML), which has proved to be an efficient and reliable method for screening new functional materials. This paper reviews the lithium solid-state electrolytes that have been discovered based on ML algorithms. The selection and preprocessing of datasets in ML technology are initially discussed before describing the latest developments in screening lithium solid-state electrolytes through different ML algorithms in detail. Lastly, the stability of candidate solid-state electrolytes and the challenges of discovering new lithium solid-state electrolytes through ML are highlighted.

Morph genetic material is a kind of new material which can not only keep natural biological fine morphology and structure but also is given new characteristics and functions. At present, the main preparation methods for biomorphic materials are chemical solution impregnation method, sound chemical processing method, and nanocomposite solvent heating method, etc. Domestic and foreign researchers have been trying to use different templates to prepare for functional materials which have different tendencies. Compared with the conventional artificial materials, these materials show obvious superiority. Morph genetic material is a new type of functional materials, mainly used as catalyst and adsorbent, playing an important role in environmental protection.

A new type of photonic crystals entitled “magnonic crystals (MC)” that exhibit forbidden gaps in the microwave spectrum of magnetostatic spin waves (MSW) are reported. The topography of the MCs that consist of two-dimensional (2-D) etched holes periodic structure in yttrium iron garnet films was studied by atomic force and magnetic force magnetometry. The propagation characteristics of spin waves in such 2-D MCs was measured and analyzed.

The intent of this chapter is to provide a basic overview of recent advances in graphene based hybrid nanostructures including their preparation, properties and potential applications in various field. The development of graphene based functional materials, has shown their tremendous interest in areas of science, engineering and technology. These materials include graphene supported inorganic nanomaterials and films, graphene-metal decorated nanostructures, Core/shell structures of nanocarbon-graphene and graphene doped polymer hybrid nanocomposites etc. They have been prepared by various methods like chemical vapor deposition of hydrocarbon on metal surface, liquid phase exfoliation of graphite, chemical reduction of GO, silver mirror reaction, catalysis, in-situ hydroxylation and sono sol-gel route, respectively. The attractive properties of graphene and their derivatives filled with metal nanoparticles (e.g. Au, Ag, Pd, Pt, Ni, and Cu) have made them ideal templates. Graphene and their derivatives have also been decorated with various semiconductor nanomaterials (e.g. metal oxides and dioxides, metal sulfides). These metal decorated graphene nanostructures can be useful as functional hybrid nanomaterials in electronics, optics, and energy based products like solar cells, fuel cells, Li-ion batteries and supercapacitors, ion exchange and molecular adsorption.
