Abandoning Assertiveness: Assessing Foreign Policy Change in Indonesia's Response to Sea‐Based Incursions

open access: yesAsian Politics &Policy, Volume 18, Issue 4, October 2026.
ABSTRACT Indonesia's responses to Illegal, Unreported, and Unregulated Fishing (IUUF) shifted from assertive measures such as publicly bombing and sinking illegal ships to legal, educational, and cooperative measures. The changes in policies undertaken are puzzling, given that Indonesian policymakers' perception of IUUF has remained the same between ...

High‐Value Utilization of Typical Vanadium‐Bearing Solid Wastes: Mineralogy, Pathways, and Perspectives

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Vanadium‐bearing solid wastes (VBSWs) have emerged as a key research priority in resource recovery and environmental remediation because of their high resource value, large generation volume, and complex phase composition. However, practical utilization of these wastes still faces major challenges, including heavy environmental burdens, ill ...

Multi‐Site Chelation Enabled by 3D‐Printed TiO2 Hydrogel Monoliths for Dynamic Ge(IV) Recovery in Fixed Beds

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Factors Influencing Minority Group Acceptance: Evidence From the 2021–2022 Korean National Human Rights Survey

open access: yesAsian Politics &Policy, Volume 18, Issue 3, July 2026.
ABSTRACT Using data from the 2021–2022 Korean National Human Rights Survey (N = 33,741), this study examines how demographic, ideological, religious, and educational factors shape acceptance of six minority groups in South Korea. Logistic regression analyses show that women, individuals with higher education and income, and those exposed to human ...

Millimeter/Nano‐Structured Metal Monolithic Catalysts: A Privileged Opportunity for Sustainable Water Purification

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Cross‐scale assembly of metal (sub) nanoparticles and/or single atoms into millimeter/nanostructured metal monolithic catalysts (Min‐SMCs) is highly appealing for sustainable water cleanup, due to energy‐efficient catalyst recyclability, high infrastructure compatibility, and low metal‐releasing risks.

Using incentive payments to promote human–carnivore coexistence

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

Guanidinium‐Based Covalent Organic Frameworks via Pore Wall Regulation: Efficient Selective Palladium Recovery From Metallurgical Wastewater

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)
