The kinetic and potential energy of a vibrating string is considered in the first-order approximation of purely transverse small amplitude linear oscillations. The energy continuity equation is obtained for an energy density having a potential that depends on second-order spatial derivatives of the pert...
In this episode of Shopify Masters, you’ll learn how one entrepreneur discovered a business idea during a trip to South Korea, quickly launched and then went back to redesign the brand.
5 Take solar energy for example. It is a good option because there is an unlimited supply of glittering sunlight. Making it work on a large scale, however, is much easier said than done. It would be cost prohibitive to take the intricate gadgets of solar ...
Importantly for the current experiment, at the end of the up cycle (Fig. 3), the dispersion curves of the quasiparticles have returned to their zero-velocity profile, but leaving on one branch a deficit where the highest energy quasiparticles have energies well below zero (Fig. 4a). Since ...
It was noted that, like gases, solids and liquids also expand upon heating. This makes intuitive sense if you think of hot molecules as violently vibrating – they push one another away, or at least if the charge (electric charge is what holds these things together) is spread just a littl...
Graphene nanomechanical resonators are the thinnest vibrating membranes imaginable1,2,3,4. They play an important role in the study of the flexural vibrations of two-dimensional (2-D) systems5. Because of their small thickness and their small mass, they constitute a nearly ideal testbed for stud...
In addition to the cantilever and cymbal structures, large numbers of thin piezoelectric materials can be arranged together along the direction of the electric field to form a stack structure. This way, the energy output can be effectively improved. Stack structure is a suitable choice for high ...

Pure aluminum, e.g., AA1060, in an annealed state has strength of about of 70 MPa, being insufficient for automotive harness to withstand the influence of vibrating parts of the engine. The aluminum alloy wire developed for EV harness exhibits high-strength and high-bending properties exceeding...
