“…On the other hand, because of their size close to the wavelength of light, and large specific surface area, they can have some special properties that are different from traditional materials [14,15]. ese properties lead to changes in the melting point, optics, electrical conductivity, thermal conductivity, mechanical properties, and magnetic properties of nanomaterials, making the materials widely used in biology, medicine, energy, environment, communication, construction, paint, optoelectronics, and other fields [16].…”

The piano is a western musical instrument. The art of piano performance has made great progress in China. Education is essential for the inheritance and development of the arts, including the piano. Piano lessons play an important role in music education and are the foundation of music education. Teachers play a leading role in the learning process. The comprehensive quality of teachers, including ideological and moral accomplishment, cultural accomplishment, work level, teaching theory, and artistic aesthetic level, directly or indirectly affects the teaching level and the growth, learning, attitude, and concept of students. Through the research and experiment on the application of composite nanomaterials in the teaching of piano touch and timbre expressiveness, the experimental data showed that after the improvement of piano touch and timbre performance by nanomaterials, the students’ interest in the piano improvisational accompaniment course has greatly increased. There were 86 people who were interested, accounting for 86.13%. There were 13 people who were not interested and indifferent, accounting for 13.87%. Compared with the increase of 36 people who were interested before the improvement, the number of people, who were not interested and indifferent, was decreased by 36 people. From the abovementioned data, it can be seen that the application of nanomaterials in piano teaching, it has made an indispensable contribution to the development of piano teaching.

“…Modern military operations and high-complexity weaponry need a continuous enhancement of improved ballistic protection armor systems that are adaptable, lightweight, comfortable, and have great energy absorption capabilities [1]. The great strength, durability, incombustibility, and capacity to protect Aramid-based fibers such as Kevlar and Twaron are most commonly utilized for safety without significantly limiting durability and user comfort [2], [3]. Several pieces of study have cited literature on the influencing elements on cloth ballistic performance [4].…”

The novelty of this research is the synthesis and comparison of a soft liquid composite shield made from two different Shear Thickening Fluids (STFs) / Polyamide fabric composite material and choosing the best one for impact resistance based on characterization and performance. The STFs microstructural properties are characterized, and STF / Polyamide composites are prepared while testing their ballistic resistance using an air gun with intermediate velocities (<100 m/s) for energy absorption. Materials used for this purpose are fumed silica with polyethylene glycol (PEG) STF and starch with water STF based dispersions. The results confirmed the superior performance of STF to absorb energy, especially for starch and water system. The rheological properties for starch/water STF showed higher viscosity than silica/PEG reaching 523.6 Pa.s and 178.9 Pa.s respectively. Other characterization tests proved the superior performance of starch with water STF leading to more dispersion stability and obvious thickening effect at higher particle concentration leading to a greater jump in viscosity at sudden shear rate. The highest concentration of silica/PEG STF/fabric showed improvement in indentation depth by 26.9%, while the starch/water STF by 43.6%. These results show the viability of the STF/Polyamide composite material if integrated for personal protection applications.

Background: The current research work reports an investigation of the effects of employing CuO and TiO2 nanoparticles as potential additives to refinery (petroleum) diesel fuel, in order to reduce the emissions of combustion process as well as to enhance the combustion process. Methods: Nanodiesel samples were prepared with various concentrations (50 ppm, 100 ppm, 200 ppm, 300 ppm). The experimental work was conducted using a four stroke diesel engine with a single cylinder at various loads in order to accurately determine the influence of nanoparticles on combustion process. The experimental readings were measured at two conditions, cold start and hot start relative to the engine. Results: It was clearly observed that the nanodiesel fuels have significantly reduced CO, CO2, NO, unburned HC, and enhanced the engine performance. According to the experimental results the 100 ppm TiO2 and 200 ppm CuO nanodiesel have showed almost the highest performance and lowest emissions comparable to neat diesel fuel and other nanodiesel samples. Owing to 100 ppm TiO2 on hot start conditions, it was found that the CO, CO2, NO, unburnt HC, exhaust temperature, and BSFC have been reduced by 41.4%, 37 %, 38.3%, 81%, 4.9%,and 20.5% respectively at maximum load. Meanwhile, the brake power, RPM and thermal efficiency have increased by 1.5%, 1% and 2.65% respectively. Conclusion: Eventually the stability of nanodiesel fuels were investigated. Accordingly, the stability of 100 ppm TiO2 and for 200 ppm CuO are 7 days and 3 days. Conclusion: Eventually the stability of nanodiesel fuels were investigated. Accordingly, the stability of 100 ppm TiO2 and for 200 ppm CuO are 7 days and 3 days.
