Influence of sulfonation degree and deposition technique on the electrical and morphological properties of sulfonated polystyrene thin films

open access: yesPolymer International, EarlyView.
Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.

Chemical diversity and phylogenetic insights into Hawaiian ʻākia (Wikstroemia) species used in traditional fishing practices

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Traditional fishing with plant‐based piscicides is a global practice in decline, facing increasing restrictions. We investigated the chemical diversity of endemic Wikstroemia species historically used to stun or poison fish in Hawaiʻi. Using 1‐H‐NMR, principal component analysis, targeted HPLC, and target‐capture sequencing, we characterized compounds ...

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

open access: yesSustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

The Role of Fire Safety in Advancing United Nations Sustainable Development Goals: A Review

open access: yesSustainable Development, EarlyView.
ABSTRACT Fire safety is an essential yet often overlooked component of sustainable development. As urbanization accelerates and climate‐related hazards intensify, integrating fire risk reduction into sustainability frameworks is becoming increasingly critical. This review employs a structured narrative methodology, synthesizing peer‐reviewed literature
