Metal-Organic Frameworks Based Multifunctional Materials for Solar Cells
Developing low-cost and stable materials for converting solar energy into electricity is vital in meeting the world’s energy demand. Metal-organic frameworks (MOFs) have gained attention for solar cells due to their natural porous architectures and tunable chemical structures. They are built by high-symmetry metal clusters as secondary building units and organic carboxylate/azolate ligands as linkers.

Modification and Application of Bamboo-Based Materials
In light of continual societal advancement and escalating energy consumption, the pursuit of green, low-carbon, and environmentally friendly technologies has become pivotal. Bamboo, renowned for its diverse advantages encompassing swift growth, ecological compatibility, robust regenerative properties, commendable mechanical characteristics, heightened hardness, and abundant availability, has discovered applications across various domains, including furniture and construction. Nevertheless, natural bamboo materials are plagued by inherent limitations, prominently featuring suboptimal hydrophobicity and vulnerability to fracture, thereby constraining their broad-scale application. Thus, the paramount concern is to enhance the performance of bamboo materials through modification.

Coating Types on the Surface of Aluminum Alloy
Aluminum alloy is widely used in many fields for its excellent performance. However, in practical application, aluminum alloy is easy to become corroded and be invalidated, owing to the influence of environmental factors. Some pollutants or corrosive media q5 its surface adhesion will further deepen the failure rate of aluminum alloy, resulting in a large amount of workforce waste, waste of material and financial resources, and energy consumption. So the anti-corrosion and anti-fouling treatment of aluminum alloy surfaces to expand their practical application range and reduce energy loss are of great significance.

Metal Oxide Quantum-Dot-g-C3N4 Nanocomposites
Quantum dots and graphitic carbon nitride (g-C3N4) are essential elements in this science. In contrast to quantum dots, which have enormous potential due to their size-dependent bandgap tunability and effective charge carrier production, g-C3N4 has properties like chemical stability and a configurable bandgap that make it a versatile material for photocatalysis.

Synthesis Strategies for Dual-Emissive Carbon Dots
Tuning the optical properties of carbon dots (CDs) and figuring out the mechanisms underneath the emissive phenomena have been one of the most cutting-edge topics in the development of carbon-based nanomaterials. Dual-emissive CDs possess the intrinsic dual-emission character upon single-wavelength excitation, which significantly benefits their multi-purpose applications.

Composite Materials Related to Bone
Bones are composite materials consisting of organic polymers (mainly type I collagen), carbonated apatite, and water, with volume fractions of 35–45%, 35–45%, and 15–25%, respectively. Carbonated apatite in bone contributes to rigidity, while organic polymers and water contribute to toughness. The inorganic crystal, carbonated apatite, is a plate-shaped crystal with dimensions of 50 nm × 25 nm × 1–4 nm, generating a significant organic–inorganic interface, due to its nanoscale size. This interface is believed to absorb externally applied forces to dissipate mechanical energy to thermal energy. Crystallization of calcium phosphate in a solution or in a dispersion of a polymer attracts interest as a biomimetic synthesis of the bone-like composites.

Biomimetic Mineralization for Enamel and Dentin
The tooth, including enamel and dentin, is a prominent biomineral that is produced by the biomineralization of living organisms. In clinical dentistry, traditional remineralization is achieved by using fluoride to enhance the deposition of calcium phosphate on the enamel surface, which is called an acid-resistant layer of fluorapatite. Despite this method having been successful in hardening enamel, the structure of this mineral layer is disordered and loose, and distinct from the natural enamel. Inspired by the process of natural enamel formation, strategies of biomimetic remineralization have been proposed and developed for several decades. These strategies include simulating in-body mineralization conditions, such as the enamel disks immersed in simulated body fluid, to mimic the function of the proteins involved in the biomineralization of the tooth, and constructing a mineralization front similar to that observed during the formation of calcified tissue. These methods allow the regrowth of HAP crystals on the enamel surface in an attempt to replicate the complex structure of the tooth and restore its mechanical properties.

Fluorescence in Smart Textiles
Fluorescence has been identified as an advantageous feature in smart fabrics, notably for the protection of humans during outdoor athletic activities, as well as for preventing counterfeiting and determining authenticity. Fluorescence in smart fabrics is achieved using dendrimers, rare earth metal compounds, and fluorescent dye. The principal method for producing fluorescent fabrics is to immerse the sample in a solution containing fluorescent agents. However, covalent connections between fluorophores and textile substates should be established to improve the stability and intensity of the fluorescent characteristics. Fabric can be fluorescent throughout, or fluorescent fibers can be woven directly into the textile structures, made of natural (cotton, silk) or synthetic (polyamide- and polyester-based) fibers, into a precise pathway that becomes visible under ultraviolet irradiation.
