A developing country perspective on vaccine-associated paralytic poliomyelitis

Bulletin of the World Health Organization, 2004
When the Expanded Programme on Immunization was established and oral poliovirus vaccine (OPV) was introduced for developing countries to use exclusively, national leaders of public health had no opportunity to make an informed choice between OPV and the ...

On the Photo‐Oxidation of Organic Photovoltaic Materials: The Case of PTQ10 and PM6 Blends With Y6‐12

Solar RRL, Volume 10, Issue 11, 15 June 2026.
Wantz et al. reveal how donor–acceptor interactions govern light‐induced degradation in organic solar cells. PTQ10 is destabilized, whereas PM6 is partially stabilized by Y6‐12. Crystallinity suppresses photo‐oxidation while modulating performance, defining key design principles for efficient, long‐lived organic photovoltaics.

Lighting the Path to Cyclic Phosphonamides via Halogen‐Bond Electron Donor–Acceptor Activation

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Cyclic phosphinamides are valuable scaffolds for optoelectronic applications, yet remain difficult to access with existing methods. Here, we highlight a mild and straightforward visible light‐driven strategy that enables the formation of cyclic phosphinamides and thiophosphinamides.

Selenium‐Incorporated Polymerized Nonfullerene Acceptors/SWCNT Composites with Polymer‐Assisted n‐Doping for High‐Performance Organic Thermoelectrics

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
Selenium‐incorporated polymerized nonfullerene acceptor PCB2Se forms a strong supramolecular complex with SWCNTs, enabling a record‐high zT of 0.29. Sequential N‐DMBI doping, mediated through a polymer‐assisted electron‐transfer pathway, successfully converts the PCB2Se/SWCNT composite into an efficient n‐type material with an impressive power factor ...
