The Core‐Periphery Model Under Additively Separable Preferences

Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.
ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Decoupling Amplitude, Energy Input and Contact Time in the Ultrasound‐Assisted Extraction of Ascophyllum nodosum Bioactives

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
This study showed that ultrasound amplitude had little influence on seaweed solubilization when energy input and contact time were controlled. Increasing energy improved solubilization and protein recovery but reduced antioxidant responses, while biomass loading affected extract composition.

Chemical Characterisation of Steam‐Distilled Essential Oils From Lemongrass (Cymbopogon citratus Stapf) and Ginger Rhizomes (Zingiber officinale Roscoe) Using FTIR and GC‐MS: Comparison of Phytochemical Composition

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Illustration of essential oil extraction coupled with characterisation. ABSTRACT Essential oils from lemongrass and ginger rhizomes contain bioactive compounds with potential for nutraceutical and pharmaceutical applications. In this study, essential oils were extracted from ginger rhizomes and lemongrass by the steam distillation method, using a ...

Extraction and Analytical Standardisation of DMPBD and Related Phenylbutenoids From Cassumunar Ginger: A Systematic Review and Quantitative Evidence Map

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Across 15 studies, extraction technologies produced nonequivalent DMPBD‐related outcomes, preventing a universal method ranking. Reliable comparison requires authenticated plant material, validated compound‐specific quantification, plant‐normalised DMPBD yield, mass balance and transparent resource‐use reporting.
