Capsules of Chemicals

Packaging certain insecticides inside tiny plastic pellets may amplify their toxicity in the environment, a new study suggests. The same chemical used naked — suspended only in water — was significantly less toxic than its capsulated counterpart, researcher Stacy Harper reported recently in the journal Environment International. The chemical in question (a “pyrethroid” whose active […]

Cancer

Last fall, the nation was riveted to the story of Brittany Maynard, a 29-year-old California woman afflicted with inoperable brain cancer. She captured the media spotlight when she moved to Oregon to access lethal drugs under Oregon’s death-with-dignity law. Maynard had chosen to die before the tumor took her autonomy.

Microcosms for Nano

Many of the products we buy — sunscreen, stain- and odor-resistant clothing, fuel additives, sports equipment — contain nanoparticles that have been designed for a purpose. These materials (about 100,000 times smaller than the width of a human hair) can block sunlight, prevent microbial growth, lubricate surfaces and confer tensile strength. However, in some cases, […]

Nanocrystals for Solar

In Alex Chang’s lab in the School of Chemical, Biological and Environmental Engineering, researchers arrange atoms in precise patterns to create materials with novel electrical and heat-transfer properties. Chang and his colleagues use electron microscopy to visualize and analyze structures that are often only a few atoms thick. “The EM facility is very important for […]

New Corvallis microtechnology firm launches line of industrial micromixers

Microflow CVO (www.microflowcvo.com), a new company spun off from research in the Oregon State University Microproducts Breakthrough Institute (MBI), has launched its first product line of stainless steel micromixers. Inside the precision-engineered devices are a multilayer network of channels designed to meet manufacturer needs in the pharmaceuticals, petrochemicals, personal care products and other industries. Dime-sized […]

Movie maker

Kate Saili’s films won’t show in theaters any time soon, but they do feature zebrafish, a rising star in molecular biology, in a dramatic role — regenerating tissues that have been injured. Saili, who grew up in Kalispell, Montana, studies the effect of nanomaterials on inflammation. She uses transgenic zebrafish whose white blood cells fluoresce […]
