With the acceleration of China’s aging trend, the physical health of the elderly needs more attention and research from us. In particular, many elderly people are prone to accidental injuries during exercise, so how to protect the health of the elderly through high-tech is worthy of more in-depth research. This measure can promote the establishment of a health system for the elderly. This article is mainly based on the research on the health promotion system of the elderly’s daily body functions based on nanoprotective gear technology. It uses the literature method to read a lot of literature to understand the current research status of the elderly’s daily body function and health and the application status of nanotechnology, through the questionnaire and survey method for testing the blood pressure, heart rate, pulse wave velocity, bone density, and other physical indicators of the surveyed elderly population, and organize and analyze the relevant data. In this survey, 28.8% of the elderly who regularly participate in physical exercise have high systolic blood pressure, 33.3% of the elderly who do not participate in exercise regularly have high systolic blood pressure, and most of them are in the low bone density stage. Therefore, nanocare technology can effectively protect the health of the elderly and provide protection during exercise. The research in this article is aimed at illustrating the establishment and improvement of the physical function and health promotion system of the elderly through the impact data on physical indicators and providing a factual basis for the elderly to better participate in physical exercise and improve the health quality of the elderly.

“…Studies have shown that adding nano-materials to polymers increases their tensile and flexural strength as well as temperature durability (35)(36)(37)(38) . Application of nano-sized boron and its derivatives as fillers in shielding materials and studying its features relative to micro-sized particles has been one of the interesting topics in both experimental and simulation studies (39) .…”

Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and thermal neutrons. A range of different nanoparticles for a spectrum of neutron energies investigated. However, there is no comprehensive review concerning the shielding properties on these newly proposed shielding materials against neutrons. The current review is an attempt to gather the information provided by the published papers in this regard. The neutron attenuation of nanocomposites and their ordinary counterparts discussed and compared. In addition, the effect of influential parameters, including particle size, neutron energy, particle type, and materials composition analyzed.

“…Good protective properties in buffering of fire and thermal shock can be obtained using composite polymer coverings with typical ablative composite matrices like silicone resin (Yuan et al, 2018), phenol resins ( Kucharczyk et al, 2013;Pulci et al, 2010;Bahramian, 2013;Zhou et al, 2019) or epoxy resins (Kucharczyk, 2010;Bakar et al, 2016;Camino et al, 2005;Kucharczyk et al, 2018;Krzyżak et al, 2018;Stawarz et al, 2019) with fillers that increase the thermal stability of a composite. Pure resins are good ablative materials.…”

The objects of the mathematical simulation were two covers of the same shape, but different geometrical dimensions. The covers were made of aramid fabric, alternating and uniformly distributed in the composite - in a polymer matrix of epoxy resin, modified with 15% addition of MMT. For each of the two guards, four variants of the composite material were considered in correlation with the metal casing, as well as three load cases, in accordance with the normative documents. A numerical analysis of dynamic tests was performed to determine the durability of the recorder. As a result of the conducted analyses, stress values were obtained in all load cases and for all kinds of placement of the composite in correlation with the metal reinforcement casing. The displacements of the entire model and stress σx were analyzed as a possible cause of delamination, while the shear stress τyz is a possible cause of inter-cutting. Also, a detailed distribution of stresses reduced in subsequent layers of the cover material was analyzed. The distribution of kinetic and potential energy during piercing of the composite thermo-protective casing was determined by numerical simulation and the design of the recorder housing made of an epoxy ablation composite, with a metal casing located inside the casing, was considered.
