Discussion on Using Character as A Method of Oral Evidence Authentication [PDF]

open access: yes, 2016
言词证据的鉴真是有难度的。一方面,言词证据所反映的案件信息是以 主体对事实进行初步加工为前提,通过言词陈述的方式向第三人传递。因 此,它的证明力很大程度上受到言说人主观因素的影响。另一方面,言词证 据包含的信息多且丰富,是还原案件事实的第一手资料。和实物证据相比, 司法人员更重视对“口供”等言词的获取,有时因为存有过分追求真相的不 良心态,又实施了非法取证的行为。因此,它的证据能力相当程度上受到取 证者的因素的影响。然而,实践中以书面形式审查言词的鉴真方式,并不能 帮助法官排除这些主观因素 ...

Oxygen Vacancy Engineering of Ultrafine ZnAl2O4 Nanoparticles as a Robust Protective Layer for Dendrite‐Free and Long‐Lifespan Aqueous Zn Metal Anodes

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Sub‐Micrometer Ag Particles Boost Luminescence and Thermal Stability of Perovskite Quantum Dot Phosphors for Light‐Emitting Diodes

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Perovskite quantum dots (QDs) have been considered as promising emitters for lighting and display applications, but they suffer from poor thermal stability under operation. Herein, we introduce sub‐micrometer Ag particles to simultaneously enhance the luminescence intensity and thermal stability of perovskite QDs.

Deep Learning–Driven Surface‐Enhanced Raman Scattering–Lateral Flow Immunoassay With Au Nanostars for High‐Accuracy Respiratory Virus Detection

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.

Ru‐Ag Dual Atom Sites for Methane Detection Enabling Intelligent Thermal Runaway Warning in Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.
