An answer is a calculation of spin-dependent adsorption energetics or kinetics that reproduces the measured effect size and its dependence on molecular length.","problem_ref":null,"references":"","settled_by":"First-principles or model calculations of spin-dependent adsorption compared with replicated adsorption-rate measurements.","status_note":"","title":"Mechanism of enantiomer-selective adsorption on magnetized surfaces","topic_ref":"101e87c59983897406e49491824c3315a243c65ce471b22cd64824fac7bdc4c3"},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"a960da97fd008f7162f8d4d5dab792da8f48ad8bc5bad3354521e7cb96008095","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"a6a0a62c61ba8876f1c2845ffec1b634d53f0c0cbffca814a568e03c8ab914a9","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"1k76kB1pTix0i93JP9BjJDUBugnDxWF-5efeUGKOdXU9KdLAsQlRLsGaAvIJJeVE3ze3duRtgi2bt4GLl_mPAw"},"schema":"pubphys.envelope/1"},"record_hash":"a960da97fd008f7162f8d4d5dab792da8f48ad8bc5bad3354521e7cb96008095","leaf_index":854}
