A superfast process for nanoscale machining

Cutting intricate patterns as small as several billionths of a meter deep and wide, the focused ion beam (FIB) is an essential tool for deconstructing and imaging tiny industrial parts to ensure they were fabricated correctly. ...

Mapping the march to methodical materials

Selective and reactive, metal-organic frameworks or MOFs could replace inefficient materials in batteries, catalysts, solid-state heat pumps, and other products where gas separation and storage are vital. While scientists ...

Pulp friction cleans up 'Brockovich' chemical

A byproduct of the manufacture of pulp using the sulfite process for making paper, sodium lignosulfonate, can be used to immobilize and soak up toxic chromium compounds from soil and water, according to research published ...

Ions control shape of nanofibers grown on clear substrate

Researchers from North Carolina State University have found a new way to develop straight carbon nanofibers on a transparent substrate. Growing such nanofiber coatings is important for use in novel biomedical research tools, ...

Percolating a solution to hexavalent chromium

The metal chromium is an essential nutrient for plant and animal metabolism, but it can accumulate to toxic and hazardous levels in the environment when discharged in industrial waste water; a point made infamous by the movie ...
