Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Improving access to new technologies: An experiment with Kenyan input sellers

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Patient‐Personalized Membrane‐Coated Magnetic Nanovectors: Probing the Biomimetic Interface for Targeted Tumor Theranostics

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents a label‐free spectroscopic platform to evaluate membrane protein conformation on patient‐derived glioblastoma cell membrane‐coated magnetic nanovectors. This work demonstrates that preserving membrane protein integrity during nanoparticle fabrication enhances homotypic tumor targeting and reduces hard protein corona formation ...

A system dynamics‐based framework for bioenergy planning in sub‐Saharan Africa: integrating circular bioeconomy and Fourth Industrial Revolution technologies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy scarcity remains a persistent challenge in sub‐Saharan Africa (SSA), where limited access to reliable, affordable, and clean energy constrains socioeconomic development. Biomass resources, including agricultural residues, forest waste, and waste from other biological sources, are widely available, but their use for modern energy ...

Theoretical georeferenced potential for biomethane production in Brazil from organic waste, including logistics and cost aspects

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract One of the challenges for biomethane production in Brazil, as well as its use, is related to transportation logistics, owing to the lack of detailed studies of the entire supply chain at a national level, which includes all the stages from waste collection to transportation for its final use.

‘…It was my choice to see how I can acquire this Western world education… and I'm happy…’: Structuration and the dialectic nature of being a Nigerian university student in the UK

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This paper examines the experiences of Nigerian cross‐border students in UK higher education, focusing on how colonial legacies continue to shape the interplay between structure and agency. Three key themes emerged in the analysis of the data: First, the persistence of a ‘West is Best’ mentality reflects the internalisation of colonial ...

A General Workflow for Tangential Flow Filtration Perfusion Scale‐Up

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Tangential flow filtration (TFF) perfusion using hollow‐fiber modules offers substantial advantages over other mammalian cell retention technologies. Recently, increased awareness of Starling flow has helped to enhance filtration performance to similar, or even higher levels compared to alternative technologies.

Biomaterials for modulating cellular responses of endogenous tendon stem/progenitor cells: A promising avenue for tendon regeneration

open access: yesBMEMat, EarlyView.
This review comprehensively summarizes emerging biomaterial‐based strategies and underlying mechanisms for modulating endogenous tendon stem/progenitor cells (TSPCs). It offers the most recent insights into TSPC physiology and potential applications of tissue engineering and regenerative medicine in tendons.
