Iron pyrite (cubic FeS2) is a promising candidate absorber material for earth-abundant thin-film solar cells. Here, we report on phase-pure, large-grain, and uniform polycrystalline pyrite films that are fabricated by solution-phase deposition of an iron(III) acetylacetonate molecular ink followed by sequential annealing in air, H2S, and sulfur gas at(More)
The five cotton cultivars viz., CB1, CB3, CB5, CB8, and C12 were evaluated under field conditions to compare their resistance levels against the aphid species Aphis gossypii (Hemiptera: Aphididae) and the jassid species Amrasca devastans (Hemiptera: Cicadellidae). The effects of plant characteristics that could explain some of the varietal resistance levels(More)
common autosomal-dominant genetic disorders with an incidence of approximately 1:3,500. Vascular abnormalities associated with NF-1 include stenotic or occlusive diseases, aneurysms, arteriovenous malformations and, rarely, arteriovenous fistula (AVF). Association of arteriovenous fistula with NF-1 is rare with a few cases of vertebral AVF having been(More)
