“…He embedded micro nanosuperparamagnetic materials in the tumor area. The results show that the use of micro nanomaterials will significantly reduce the temperature of healthy tissues around cancer cells, so as to achieve a more favorable therapeutic effect [6]. To sum up, after the exploration in recent years, the application of micro nanotechnology has been deeply studied by many scholars, but there is not much research on the aesthetic practice of architectural sculpture art.…”

Micro nanotechnology refers to the emerging technology of material production using a single atomic or molecular structure. The structure and size of materials range from one to 100 microns or nanometers. In this paper, micro nanotechnology is used to study the aesthetic practice of sculpture technology and architectural sculpture art. This paper aims to combine traditional art ideas with science and technology to promote common development. This paper first introduces the micro nanoengraving technology and architectural sculpture art, it includes the definition of works, classification of works, and research on artistic commonalities and differences, and then summarizes the characteristics of micro nanoengraving materials. Finally, this paper will carry out aesthetic practice of sculpture works based on micro nanocreation. Finally, this paper compares with the works created by traditional technology. The results show that the recognition and creativity evaluation of sculpture works based on micro nanocreation have reached more than 8 points. It verifies the effectiveness of the technology.

“…They concluded that uncertainties in the measurement of some parameters, such as strength of electromagnetic field, radius, and area of the micro/nanoparticle severely affect the temperature distribution in the tissue. In other work, Taheri and Talati [24] examined the hyperthermia cancer treatment by considering the two-dimensional transient model of biological tissue with SPM and PCM. Results showed that the use of the PCM reduces the temperatures up to 3°C.…”

In thermal protection of healthy tissues during hyperthermia with the phase-change micro/nanomaterials, the impossibility of performing a similar experiment with the theo retical parameters is inevitable because of different errors such as modeling, measuring, particle deposition area, etc. These errors may affect the practical thermal protection from damaging the healthy tissue or not destroying the tumor tissue. T o perform a numerical procedure, the electrical potential is obtained solving the Laplace equation and the Pennes Biothermal equation is used to find the temperature distribution in the tissue using the finite difference method. T he Pennes equation is transiently resolved by considering intracellular conductance, blood perfusion, and metabolic heating. Consequently, the deviation and the uncertainty of each parameters in the thermal protection including the concentration of the phase change material, the radius of microcapsules, the latent heat, the melting point, the temperature range of phase change of micro/nanoparticles, and the concentration and the radius of the superparamagnetic materials are investigated. According to the results of the uncertainty analysis, the radius of the superparamagnetic materials is the most important parameter so that a 20% deviation from the numerical value changes the temperature of the tissue up to 4 °C.

“…4 The energy storage density of phase change storage is high, and it can also have a small temperature difference in the process of storing and releasing energy. 5 Phase change material (PCM) is a functional material that can store and release a large amount of latent heat energy under slight temperature changes. 6 Due to its high latent heat density, constant phase change transition temperature, and no phase separation, PCM has been widely used in various applications, such as solar storage, 7 smart textiles, 8 thermal protection of electronic equipment, 9 waste heat recovery, 10 and smart houses.…”

This study presents a composite phase change material (CPCM) that uses emulsion polymerization to prepare crosslinked poly(N-hydroxymethyl acrylamide) (PN-MA)/polyethylene glycol (PEG) interpenetrating polymer network (IPN) eutectic microspheres. X-ray diffractogram shows that even after adding PN-MA for cross-linking, the PEG eutectic still exhibited crystallization ability. Differential scanning calorimetry shows that the CPCM melted at 31.58 °C with 94.61 J/g and solidified at 38.02 °C with 88.63 J/g. Thermogravimetric analysis suggested that the CPCM can be applied to thermal energy storage. After 25 thermal cycles, there was a change in the macrostructure of the CPCM and the latent heat of phase change. Scanning electron microscopy results shows that the CPCM is a kind of microsphere with uniform particle size distribution. The CPCM is expected to be used in fields such as smart textiles, thermal insulation materials, and industrial waste heat utilization.
