“…Organic/inorganic nanomaterial coatings can not only overcome the shortcomings of simple inorganic particles, poor stability of organic polymers, low strength, etc., but also can obtain better performance than inorganic particles and organic polymers under the combined action of the two, such as excellent performance in the mechanical, electrical, thermal and optical aspects of materials. Therefore, this type of new material, which combines many characteristics of inorganic, organic and nano, has better performance as a structural material [73][74][75][76].…”

Nano-coating has been a hot issue in recent years. It has good volume effect and surface effect, and can effectively improve the mechanical properties, corrosion resistance and wear resistance of the coatings. It is important to improve the wear resistance of the material surface. The successful preparation of nano-coatings directly affects the application of nano-coatings. Firstly, the preparation methods of conventional surface coatings such as chemical vapor deposition and physical vapor deposition, as well as the newly developed surface coating preparation methods such as sol-gel method, laser cladding and thermal spraying are reviewed in detail. The preparation principle, advantages and disadvantages and the application of each preparation method in nano-coating are analyzed and summarized. Secondly, the types of nano-coating materials are summarized and analyzed by inorganic/inorganic nanomaterial coatings and organic/inorganic nanomaterial coatings, and their research progress is summarized. Finally, the wear-resistant mechanism of nano-coatings is revealed from three aspects: grain refinement, phase transformation toughening mechanism and nano-effects. The application prospects of nano-coatings and the development potential combined with 3D technology are prospected.

“…With the rapid development of nanobiotechnology, synthetic stimuli‐responsive biomaterials have drawn significant attention due to their promising applications in fields of biomedicine and pharmacy, such as drug delivery, biosensor, and tissue adhesion . Such materials display rapid changes in structure, solubility or polarity upon external (e.g., temperature, light, mechanical force, and electrical or magnetic field) or internal (e.g., pH, redox, and enzyme) triggers . The use of these materials as drug nanocarriers could accurately deliver drugs at the target sites in a controlled and safe manner, thus avoiding toxic side effects caused by damaging the healthy tissues …”

Engineering of smart photoactivated nanomaterials for targeted drug delivery systems (DDS) has recently attracted considerable research interest as light enables precise and accurate controlled release of drug molecules in specific diseased cells and/or tissues in a highly spatial and temporal manner. In general, the development of appropriate light‐triggered DDS relies on processes of photolysis, photoisomerization, photo‐cross‐linking/un‐cross‐linking, and photoreduction, which are normally sensitive to ultraviolet (UV) or visible (Vis) light irradiation. Considering the issues of poor tissue penetration and high phototoxicity of these high‐energy photons of UV/Vis light, recently nanocarriers have been developed based on light‐response to low‐energy photon irradiation, in particular for the light wavelengths located in the near infrared (NIR) range. NIR light‐triggered drug release systems are normally achieved by using two‐photon absorption and photon upconversion processes. Herein, recent advances of light‐responsive nanoplatforms for controlled drug release are reviewed, covering the mechanism of light responsive small molecules and polymers, UV and Vis light responsive nanocarriers, and NIR light responsive nanocarriers. NIR‐light triggered drug delivery by two‐photon excitation and upconversion luminescence strategies is also included. In addition, the challenges and future perspectives for the development of light triggered DDS are highlighted.

“…Stimuli-responsive materials have much attentions in a variety of fields such as organic, inorganic, and biochemistry. [1][2][3][4][5][6][7][8][9][10][11] In particular, stimuli-responsive fluorescent materials have been developed and researched for past decades because their materials can provide obviously and easily visible changes in fluorescent colors. 5,7,[12][13][14] In the dilute solution state, designer molecules programed by noncovalent intermolecular interactions can selectively recognize the target substance such as molecule or ionic species, [15][16][17] however, the solution system demands a solubility of molecules to media used.…”

We report on stimuli-responsive behaviors for room temperature fluorescent liquid materials based on N-heteroacene frameworks in response to HCl vapor. These liquid materials as well as their mixtures prepared by varying the combination can provide various emission colors and stimuli-responsive properties in liquid states. Also, we achieved the improvement for total synthetic yield (>40%) by redesigning of molecular structures of liquid materials as compared with previous liquid materials (<10%).
