Directly converting sunlight into hydrogen fuels using particulate photocatalysts represents a sustainable route for clean energy supply. Organic semiconductors have emerged as attractive candidates but always suffer from optical and exciton recombination losses with large exciton “dead zone” inside the bulk material, severely limiting the…[Read more]

From telephone interviews with 6 LHDs, 1 question was removed and 2 questions were added to the interview record.

Antibiotic-resistant gonorrhea could occur in Illinois at any time. Monitoring for antibiotic-resistant gonorrhea cases is necessary as gonorrhea morbidity continues to increase. This procedure may prove to be a model for other…[Read more]

The kinetics of diffusion-dependent phase transformations (including austenitisation of ferrite in dual steels or ferritic nodular cast irons) is very often described by the Johnson-Mehl-Avrami-Kolmogorov (JMAK) equation. This description is not complete when the conversion is only partial due to insufficient overheating, as the equilibrium…[Read more]
