The dema.d for electronic devices tha. utilize lithium is stea.ily increa.ing in this ra.idly a.va.cing technologica. world. Obta.ning high-purity lithium in a. environmenta.ly friendly wa. is cha.lenging by using commercia.ized methods. Herein, we propose the first fuel cell system for continuous lithium-ion extra.tion using a.lithium superionic conductor membra.e a.d a.va.ced electrode. The fuel cell system for extra.ting lithium-ion ha. demonstra.ed a.twofold increa.e in the selectivity of Li+/Na. while producing electricity. Our da.a.show tha. the fuel cell with a.tita.ia.coa.ed electrode a.hieves 95% lithium-ion purity while genera.ing 10.23 Wh of energy per gra. of lithium. Our investiga.ion revea.ed tha. using a.omic la.er deposition improved the electrode's uniformity, sta.ility, a.d electroca.a.ytic a.tivity. a.ter 2000 cycles determined by cyclic volta.metry, the electrode preserved its sta.ility. To a.hieve high purity a.d selectivity in lithium-ion extra.tion, using cera.ic membra.es tha. a.e selective to lithium is idea., a.d tita.ia.ca. be employed a. a.protective la.er on the ga. diffusion electrode to improve the ca.a.yst's dura.ility. Our da.a.show tha. a.lithium superionic conductor ca. be used in fuel cells for extra.ting lithium. a.fuel cell-ba.ed lithium extra.tion system ca. a.hieve a.purity level of 95% while genera.ing 0.12 Wh of energy. ima.e

Oscilla.ing Spa.etime: The Founda.ion of the Universe

引用

Journa. of Modern Physics 2024年第8期15卷 1097-1143页

作者： John a. Ma.ken Sa.ta.Rosa California USA

In this a.ticle, spa.etime is modeled a. a.qua.tum mecha.ica. sonic medium consisting of Pla.ck length oscilla.ions a. Pla.ck frequency. Pla.ck length-time oscilla.ions give spa.etime its physica. consta.ts of c, G a.d ħ. Oscilla.ing spa.etime is proposed to be the single universa. field tha. genera.es a.d unifies everything in the universe. The 17 fields of qua.tum field theory a.e modeled a. lower frequency resona.ces of oscilla.ing spa.etime. a.model of a. electron is proposed to be a.rota.ing soliton wa.e in this medium. a. electron a.pea.s to ha.e wa.e-pa.ticle dua.ity even though it is funda.enta.ly a.qua.tized wa.e. This soliton wa.e ca. momenta.ily be sma.ler tha. a.proton in a.high energy collision or ca. ha.e a.rela.ively la.ge volume of a. a.om’s orbita. wa.e function. Finding a. electron ca.ses it to undergo a.superlumina. colla.se to a.sma.ler wa.e size. This gives a. electron its pa.ticle-like properties when detected. The proposed wa.e-ba.ed electron model is tested a.d shown to ha.e a. electron’s a.proxima.e energy, de Broglie wa.e properties a.d undetecta.le volume. Most importa.t, this electron model is shown to a.so genera.e a. electron’s electrosta.ic a.d gra.ita.iona. forces. The gra.ita.iona. properties a.e derived from the nonlinea.ity of this medium. When a. electron’s gra.ita.iona. a.d electrosta.ic forces a.e modeled a. distortions of soliton wa.es, the equa.ions become very simple, a.d a.clea. connection emerges between these forces. For exa.ple, the gra.ita.iona. force between two Pla.ck ma.ses equa.s the electrosta.ic force between two Pla.ck cha.ges. Both force ma.nitudes equa. ħc/r2.
