Que este patrón aparezca sobre silicio y sin plomo abre la puerta a memorias y sensores más chicos y menos contaminantes, aunque todavía falta mucho para verlos en un producto. El estudio muestra que se puede lograr en laboratorio, pero solo con un número limitado de muestras y condiciones muy controladas.","quienFirma":"Helmholtz-Zentrum Berlin (HZB)","confianza":"revisado","consulta":null},"sello":{"hash":"02deb37a2c63a2e9970bf30bab741c367478e9fa7af012602c75bc098997a535","sello":"e2cf540859a5b52875e02d38d09fd6e6c0568d6ebd52831820706e318c3bee9a","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6583893,"aleatorio":"5eac37d72ff4b53b352f670156f0972c81dcf046654b05a30c4dfa63c53a0859","tiempo":"2026-10-25T17:03:30.000Z"},"nist":{"cadena":2,"pulso":1999140,"salida":"C468C61569266864E9211172294B83285086D642B47CA878E68C7A193732D693CD0C4998192CB1B9EC560A71BBBECA84FC5060A33FBBC98CB3203171174A1F24","tiempo":"2026-10-25T17:03:00.000Z"},"noAntes":"2026-10-25T17:03:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 25 17:03:58 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Patterns of polar vortices discovered in lead-free superlattices on silicon","descripcion":"A team at HZB has, for the first time, reported polar vortices in (BaTiO₃/SrTiO₃)₁₀ superlattices on silicon.
