Report: culvert repairs pose environmental risks, require safeguards

A new report recommends that states require standardized testing to safeguard against environmental contamination caused by a widely used method for rehabilitating aging drainage culverts.


Nanoshaping method points to future manufacturing technology

A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as 'plasmonic metamaterials' for advanced technologies.


Study: Invasive species can dramatically alter landscapes

Invasive plant and animal species can cause dramatic and enduring changes to the geography and ecology of landscapes, a study from Purdue University and the University of Kentucky shows.


GermaniumGermanium comes home to Purdue for semiconductor milestone

A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 – the purified germanium semiconductor – and now researchers here are on the forefront of a new germanium milestone.


Toxin from tobacco smoke could increase pain in spinal cord injury and worsen multiple sclerosis

A neurotoxin called acrolein found in tobacco smoke that is thought to increase pain in people with spinal cord injury has now been shown to accumulate in mice exposed to the equivalent of 12 cigarettes daily over a short time period.


Pol batteriesNanoparticle network could bring fast-charging batteries

A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.
