Competing Charge Separation Pathways Govern Charge Generation in Organic Photovoltaic Blends: Insights From Transient Electron Spin Resonance

Advanced Energy Materials, Volume 16, Issue 40, 28 October 2026.
Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...

Prevalence of eaeA and qacEΔ1 genes in Escherichia coli isolated from omphalitis in baby chicks [PDF]

Benha Veterinary Medical Journal, 2017
A total of two hundred diseased Saso chicks with omphalitis were examined (1400 samples) for the isolation of E. colifrom different organs (liver, caecum, spleen, heart, lung, yolk sac and cloacal swab). Results showed that 64 cases werepositive with an incidence of 32%. Fifty isolates (25%) of E.

Identification of EaeA protein in the outer membrane of attaching and effacingEscherichia coliO45 from pigs [PDF]

FEMS Microbiology Letters, 1995
We have previously reported that the production of attaching and effacing lesions by Escherichia coli O45 isolates from pigs is associated with the eaeA (E. coli attaching and effacing) gene. In the present study, expression of the EaeA protein, the eaeA gene product, among swine O45 E. coli isolates was examined.

Occurrence, diversity and antimicrobial resistance of Enterobacterales isolated from artisanal ‘coalho’ cheese produced in north‐eastern Brazil

International Journal of Dairy Technology, Volume 79, Issue 3, July‐September 2026.
Artisanal ‘coalho’ cheese from north‐eastern Brazil harbours diverse Enterobacterales, including strains with antimicrobial resistance, virulence‐associated genes and biofilm‐forming ability. Although resistance levels were generally low, the findings highlight the need for improved hygienic practices and continuous microbiological surveillance within ...
