Preparation of MXene/Elastomer Nanocomposites
Two-dimensional (2D) transition-metal carbon/nitrogen/carbon nitride (MXene) has extremely high conductivity and easily modifiable surface functional groups. Compared with graphene, another 2D layered material, MXene is easily dispersed in water owing to its hydrophilic groups. Its unique characteristics make MXene a valuable material. Nanocomposites can be endowed with functionality when MXene is compounded with an elastomer. Particularly in electromagnetic interference shielding and sensing, MXene exhibits extraordinary properties.

Preparation of Carbon Nitride-Based S-scheme Photocatalyst
Energy shortages are a major challenge to the sustainable development of human society, and photocatalytic solar energy conversion is a potential way to alleviate energy problems. As a two-dimensional organic polymer semiconductor, carbon nitride is considered to be the most promising photocatalyst due to its stable properties, low cost, and suitable band structure. The development of carbon nitride-based S-scheme photocatalysts has been flourished, which has raised the wave of interests and reached a crescendo in the field of energy catalysis. Therefore, a timely overview on the recent progress of carbon nitride-based S-scheme heterojunctions is highly desirable, not only to unveil the basic working mechanism, but also to inspire future research directions in carbon nitride-based heterojunctions.

Preparation Methods for Large-Area Perovskite Solar Cells
Solar energy is one of the most encouraging, abundant, green, and renewable sources for decreasing or even replacing traditional energy in the future. The energy provided by the sun in one hour is sufficient to supply the Earth’s needs for an entire year. The recent rapid development in perovskite solar cells (PSCs) has led to significant research interest due to their notable photovoltaic performance, currently exceeding 25% power conversion efficiency for small-area PSCs. The materials used to fabricate PSCs dominate the current photovoltaic market, especially with the rapid increase in efficiency and performance.

Preparation and Combustion Mechanism of Boron-Based High-Energy Fuels
Due to the characteristics of high energy density and a high calorific value, boron has become a high-energy fuel and shows great potential to be a high-performance candidate for propellants. However, the wide applications of boron are still limited by the characteristics of easy oxidization, ignition difficulty, a long combustion duration, and combustion products that readily adhere to the surface and inhibit full combustion. The boron-based energetic materials can be prepared by surface coating, mechanical milling, and ultrasonic mixing methods. The boron-based composites with different additives had different combustion characteristics. The combustion of boron-based energetic materials can be optimized by removing surface oxide layers, providing extra heat, inhibiting the formation of or the rapid removal of the combustion intermediates, and increasing the diffusion rate of oxygen.

Preliminary Activation of the Surface of Fibrous Materials
Pre-activation is often used to increase the adhesion of coatings to the surface of fibrous materials. This consists in various kinds of treatment soft the fibers, as a result of which their near-surface layer is transformed, new active oxygen-containing groups are formed, and the fiber becomes less smooth.
