From Policy Neglect to Research Agenda: Administrative Burdens and Donor‐Conceived Mobilization
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Donor‐conceived adults are a growing population, mobilizing against the very regulatory arrangements that determined the terms into which they were conceived. In Canada and the United States, where donor conception remains persistently under‐regulated, gamete donation policy has historically prioritized the presumed needs of donors, recipient ...

The Problem With Problem Load: Reconceptualizing Load in the Multiple Streams Framework
Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT What happens when policymaking systems buckle under pressure, disrupting consensus and stalling decision‐making? Drawing on the Multiple Streams Framework, we show that the existing concept capturing this stress, Problem Load, has been both misinterpreted and overstretched.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Surface‐enhanced Raman scattering (SERS) has emerged as a highly sensitive and specific technique for tumor imaging, owing to its narrow spectral features, resistance to photobleaching, and capability for multiplexed detection. However, its clinical translation remains limited by poor tissue penetration and the absence of intrinsic anatomical ...

, 1984 铜、钴、镍、铅、锌、镉极谱分析,难点在于钴和锌的测定。在多种底液中,钴和锌半波电位相当接近,不能连续测定。文献成功地分开了钴、锌和镍波。文献利用钴波的不可逆性,逆向电压扫描测定锌。有人以萃取—反萃取方式将铜、钴、镍和铅、锌、镉分成两组实施测定。 本工作试验了用萃取—反萃取法分离,极谱测定红土矿中铜、钴、镍、铅、锌 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured
