Like batteries, the proposed LI-TENGs are compact and can be rapidly assembled spliced without additional wires.
Abstract Spark discharge is essential for extracting energy from triboelectric nanogenerators (TENGs). However, the lack of universal technical standards most switches limits their widespread application. Herein, a buck circuit utilizing gas tube (GDT) as presented. The GDT switch significantly enhances instantaneous power to 30 mW, 15 times higher than direct method. When V (the breakdown voltage GDT) ≤1000 V, it can be integrated with an LC converter, forming GDTx‐Buck maximum conversion...
Abstract The integration of triboelectric nanogenerator (TENG) with electromagnetic generator (EMG) holds promise for the efficient harvesting broadband wind energy, yet challenge coupling these two systems into one high‐durability unit has persisted. Herein, a novel magnetic attraction principle is proposed to enable seamless switching between TENG and EMG across varying rotation speeds without need additional mechanical components, thereby enhancing energy efficiency magnetotropic hybrid...
The annealing effects on Pb0.97La0.03Sc0.45Ta0.45Ti0.1O3 (PLSTT) ceramics prepared by the solid-state reaction method are systemically investigated using experimental and theoretical techniques. Comprehensive studies performed PLSTT samples varying time (AT) from t (=0, 10, 20, 30, 40, 50 60) h. properties involving ferroelectric polarization (FP), electrocaloric (EC) effect, energy harvesting performance (EHP) storage (ESP) reported, compared contrasted. All these features seen to gradually...
The two-dimensional MoSi 2 N 4 monolayer as a representative material in the MA Z system has excellent light absorption properties. This article uses first-principles calculations to explore effect of Z-site atoms on study found that lattice structure MoSi2N4 did not change significantly after doping with P at site. After 25% atoms, performance is slightly reduced, and peak moves direction ultraviolet light. When we replaced all number excited states visible region greatly increased....
The optical absorption properties of the two-dimensional (2D) MoSi2N4 monolayer is often a focus research. By semi doping Cr and W at M sites, influence M-site atoms on MA2Z4 series materials was investigated. results show that atomic layer spacing 2D has some changes after elements, but entire crystal structure not significantly different. makes have an additional peak, highest peak Mo0.5Cr0.5Si2N4 large red shift corresponding to wavelength, width also greatly improved. element in...
