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

American 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

An Exploratory Study on Graphene‐Based Hybrid Epoxy Coatings for Corrosion Resistance and Self‐Healing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Corrosion of metallic process equipment in chemical, marine, and offshore industries leads to significant maintenance costs and safety concerns. Conventional epoxy coatings, though widely applied, often deteriorate under harsh conditions due to microcracking, moisture ingress and lack of self‐healing capability.
