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

Nanostructured Electrodes for Organic Solar Cells: Analysis and Design Fundamentals

open access: yes, 2012
Nanostructured electrodes (NEs) improve optical absorption and charge collection in photovoltaic (PV) devices. Traditionally, the electrodes have been designed exclusively for higher optical absorption.

Evaluating the (comparative) safety profile of the novel oral polio vaccine type 2 using individual case safety reports in VigiBase

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Novel oral polio vaccine type 2 (nOPV2) was used under the WHO emergency use listing for circulating vaccine‐derived polio virus (cVDPV) outbreaks from 2021 to 2023. We assessed nOPV2 adverse events following immunization (AEFIs) and compared its safety profile to other vaccines using VigiBase.

Relative odds of shedding vaccine poliovirus after challenge among individuals vaccinated with IPV in addition to OPV compared with individuals vaccinated with OPV only.

open access: yes, 2012
Labeling as for Figure 2. The schedule indicates the number and type of OPV doses received by both groups and the number of doses of IPV that were added in the intervention group. In two studies, IPV was administered simultaneously with OPV at 6, 10, and

Three‐Step Synthesis Toward Fluorene‐Based Non‐Fused‐Ring Acceptors for Organic Solar Cells

open access: yesChemistry – A European Journal, EarlyView.
Applying a simple three step synthesis strategy leads to two fluorene‐based non‐fused‐ring electron acceptors, FHM‐Cl and FHM‐F for organic solar cells. The chlorinated variant delivers markedly higher efficiency due to broader light harvesting and favorable molecular packing, resulting in improved charge transport and reduced recombination losses ...
