A very fast way to continuously synthesize zeolites

For a long time, it has been believed that the crystallization of zeolites is, by nature, a very slow process. The hydrothermal synthesis of zeolites is normally performed batchwise, requiring crystallization times on the order of days. Now, Toru Wakihara…

Australians move to supply vanadium for redox flow batteries

Two Australian companies — Australian Vanadium Ltd. (AVL; www.australianvanadium.com.au) and TNG Ltd. (both Perth; www.tngltd.com.au) — are now able to produce commercial-grade vanadium electrolyte for use in vanadium redox-flow batteries (VRFBs). Those batteries are increasingly gaining favor, primarily for grid-scale…

An inexpensive adsorbant for removing silver from wastewater

The release of silver from industrial wastewater has caused serious environmental problems. Many methods have been developed to remove silver ions from industrial wastewater, including chemical precipitation, ion exchange, electrolysis, replacement, membrane and reverse osmosis. Several adsorbents have been used…

A process for making longer carbon nanotubes

A new commercial manufacturing process for carbon nanotubes (CNTs) produces tubes in the range of 1–10 mm in length (5–12-nm dia.), two orders of magnitude longer than currently available CNTs, which typically have lengths from 5–20µm. “Despite attractive mechanical and…

Additives retain starch in cardboard recycling

Starch is essential for imparting strength to corrugated cardboard boxes, but millions of tons of starch are lost in cardboard recycling processes annually because conditions are ripe for bacteria to thrive, and the microorganisms degrade starch by converting it to…
