“…Literature [28] puts forward the view of the essence of curriculum: curriculum is what is taught in school; curriculum is a series of subjects; curriculum is the content of teaching materials; the course is a learning plan; the course is a series of materials; courses are subject order; curriculum is a series of behavioral goals; curriculum is the learning process; the curriculum is a variety of activities carried out in the school, including extracurricular activities, counseling, and interpersonal communication; curriculum is what is taught inside and outside the school under the guidance of the school; curriculum is anything designed by all the staff of the school; curriculum is the experience of learners in school; and curriculum is a series of experience gained by individual learners in school education.

Physical education is an essential part of a child’s education. With the extensive reform of education in recent years, the old physical education teaching mode now faces a situation of low teaching efficiency, low student learning efficiency, low student interest, and lack of classroom participation, which is incompatible with the spirit of modern education and the needs of social development. Smart classrooms are emerging to meet the demands of the new curriculum reform. Smart classroom teaching is a good teaching concept: physical education teaching should reflect experience, generation, innovation, and morality. In physical education, the situational teaching method is a new teaching mode. It replaces the old boring and assembly-line teaching method with a method that allows students to take control of the classroom. Smart classrooms have emerged as a new hot spot in school information teaching due to the rapid development and widespread application of the new generation of information technology, as well as the deepening integration of information technology and teaching.

“…MOFs exhibit a lot of attractive properties such as a large specific surface area (10 400 m 2 g −1 ), high porosity (90%), high loading efficiency, uniform structural nano scale cavities, tunable pore sizes (from micropores to mesopores), easy functionalization and post synthetic modification, thermal and water stability, biocompatibility and biodegradability which make them much better materials compared to graphene, graphene oxides, carbon nanotubes, gold nanoparticles, silver nano particles and magnetic nano particles. 1,2 These attractive properties have made MOFs promising candidates for different applications such as sensing (biosensing, chemo-sensing, photochemical and electrochemical sensing), [3][4][5] catalysis (photocatalysis, bio-catalysis, electrocatalysis), [6][7][8] adsorption (toxic pollutant, antibiotics, and gas adsorption, wastewater treatment), [9][10][11][12] storage (gas storage, electrochemical charge storage, batteries/energy/fuel cell storage) 13 and drug delivery systems. [14][15][16][17] To obtain MOFs with desired properties for specific applications, it is important to pay attention to the synthesis route and conditions.…”

“…Several semiconductors like ZnO, CdS, GaN, ZnS, etc. − exhibit piezoelectric properties. Numerous ceramic materials like lead zirconate titanate (PZT), various perovskites such as BaTiO 3 , ZnSnO 3 , MAPbX 3 , FAPbI 3 , etc., − and polymers (PVDF, PVDF-TrFE, PVDF-HFP, PDMS, etc.) also show a strong piezoelectric effect. ,− But most of them are not flexible, but rather brittle and toxic, making them inappropriate for device fabrication.…”

With the contemplations of ecological and environmental issues related to energy harvesting, piezoelectric nanogenerators (PNGs) may be an accessible, sustainable, and abundant elective wellspring of energy in the future. The PNGs’ power output, however, is dependent on the mechanical energy input, which will be intermittent if the mechanical energy is not continuous. This is a fatal flaw for electronics that need continuous power. Here, a self-charging flexible supercapacitor (PSCFS) is successfully realized that can harvest sporadic mechanical energy, convert it to electrical energy, and simultaneously store power. Initially, chemically processed multimetallic oxide, namely, copper cobalt nickel oxide (CuCoNiO4) is amalgamated within the poly(vinylidene fluoride) (PVDF) framework in different wt % to realize high-performance PNGs. The combination of CuCoNiO4 as filler creates a notable electroactive phase inside the PVDF matrix, and the composite realized by combining 1 wt % CuCoNiO4 with PVDF, coined as PNCU 1, exhibits the highest electroactive phase (>86%). Under periodic hammering (∼100 kPa), PNGs fabricated with this optimized composite film deliver an instantaneous voltage of ∼67.9 V and a current of ∼4.15 μA. Furthermore, PNG 1 is ingeniously integrated into a supercapacitor to construct PSCFS, using PNCU 1 as a separator and CuCoNiO4 nanowires on carbon cloth (CC) as the positive and negative electrodes. The self-charging behavior of the rectifier-free storage device was established under bending deformation. The PSCFS device exhibits ∼845 mV from its initial open-circuit potential ∼35 mV in ∼220 s under periodic bending of 180° at a frequency of 1 Hz. The PSCFS can power up various portable electronic appliances such as calculators, watches, and LEDs. This work offers a high-performance, self-powered device that can be used to replace bulky batteries in everyday electronic devices by harnessing mechanical energy, converting mechanical energy from its environment into electrical energy.
