Modified PU foam shows promise as sponge for soaking up oil spills

Scientists from the Chinese Academy of Sciences (Beijing; www.cas.ac.cn) have found a way to transform polyurethane (PU) foam into a sponge that is strongly water-repellent and oil-absorbing, making it suitable for soaking up chemicals and petroleum from spills. One of…

A bio-butadiene plant is planned

On the heels of its successful scaleup of bio-butanol, Cobalt is looking for pathways to use that molecule as a building block for other products. The company has announced plans to build the first bio-butadiene plant in Asia. Projected to…

Nanowires improve the properties of metal composites

Freestanding nanowires exhibit ultrahigh elastic-strain limits (of up to 7%) and yield strengths. However, it has been difficult to exploit their properties in bulk composites, due to the mismatch between the elasticity of the nanowires and the elasticity of the…

A biotech process that might benefit sharks

Squalane, an emollient used in cosmetics, will be the first product of a biotechnology pilot plant now being started up by Nucelis Inc. (San Diego, Calif.; www.nucelis.com), a spin-off from Cibus (also of San Diego). The plant will use Cibus’…

A gas turbine with low NOx emissions

NEDO  and Hitachi Ltd. (Tokyo, www.hitachi.com) have developed a new combustion technology that could reduce the emissions of oxides of nitrogen (NOx) to below 10 ppm without the addition of diluents. As part of the CCS-IGCC project (carbon capture and…

Bio-butanol scaleup moves ahead with trials

In April development tests, Cobalt Technologies (Cobalt; Mountain View, Calif; www.cobalttech.com) produced n -butanol at the fermentation scale of 100 m3 per run, demonstrating lower production cost than butanol produced from petroleum. This represents production that is a factor of…

Burner technology enables reduced NOx with short flame length

To comply with increasingly stringent regulations for NOx emissions, operators of industrial plants often turn to low-NOx burners to avoid much more costly post-combustion treatment approaches like selective catalytic reduction (SCR). But low-NOx burners are plagued by significant losses in…

These scavengers of water pollutants have a magnetic attraction

A process that uses magnetic nanoparticles, coated with a reactive material, to clean up contaminated water for human use is being developed at Stanford University (Stanford, Calif.; www.stanford.edu). The nanoscavengers, as they are called, are distributed in the water to…
