Recent transient absorption experiments on CdS nanorods suggest that photoexcited holes rapidly trap to the surface of these particles and then undergo diffusion along the rod surface. In this Letter, ...

Brownian diffusion is a ubiquitous mechanism of transport for ions, molecules and submicrometre particles. It can limit the rate of chemical reactions as well as determine the efficiency of ...

Evidence has been secured that when colon bacilli or streptococci are injected in large numbers into the peritoneal cavity of dogs or rabbits, they begin to enter the blood through the thoractic duct ...

A groundbreaking study reveals the existence of at least two independent mechanisms for iron absorption from non-meat sources -- and a potential treatment for iron deficiency, the most common nutrient ...

Passive diffusion plays an essential role in oral absorption of drugs through the gastrointestinal tract, penetration across the blood-brain barrier to reach Central Nervous System disease targets, ...

This is a preview. Log in through your library . Abstract Two rice cultivars, Xiushui 48 and S. Andrea, with significant difference in selenium (Se) concentrations in brown rice grains, were chosen to ...

Strategically designing heterostructures incorporating highentropy metal particles and carbon fibers can enhance the defect ...
