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

PLANTS, 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 ...

Effect of Hydroxyl‐Terminated Polybutadiene Grade on Rheology and Settling of High‐Solids Mixtures of Mock Propellants

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT The most common binder used in composite rocket propellants is based on the pre‐polymer hydroxyl‐terminated polybutadiene (HTPB). It has been shown to have excellent mechanical properties and a long life once crosslinked, and studies have examined the kinetics of crosslinking and pot life of energetic formulations with HTPB.

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

Sustainable 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

Sustainable 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

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.
