This fiber technology could revolutionize building construction

With the Texoversum (photo), Reutlingen University (Germany; www.reutlingen-university.de) has put into operation a training and innovation center for the textile industry that is unique in Europe. The almost 2,000-m2 textile-like façade of the new building combines the innovative power of…

New adsorbent removes radioactive cesium ions from nuclear wastewater

One of the major byproducts of the nuclear fission process used for power generation is 137Cs, a radioactive isotope of Cs that has a half-life of 30 years and is often removed from nuclear-power-plant wastewater via selective adsorption using ion…

A biomimetic process to make soft fibers for smart textiles

For intelligent textiles to function effectively, they need to be strong, stretchable and electrically conductive. However, fabricating fibers that possess these three properties has been challenging. Drawing inspiration from how spiders spin silk to make webs, an international team of…

Electrochemical amalgamation effectively removes mercury from concentrated H2SO4

It is well known that mercury is not only toxic, but is also highly mobile. As a result, Hg emissions from both industrial processes (gold mining, combustion of fossil fuels, cement production, waste incineration and more), as well as natural…

Carbon nanotube coating could expand the applications for superlubricity

When a sliding interface experiences a coefficient of friction (CoF) below 0.01, the situation is said to have superlubricity. In the past, superlubricity has been limited to the microscale in controlled environments, and to ceramic surfaces with polar-fluid lubrication. Now,…

Observing particle concentrations and velocities inside a fluidized bed

Fluidized beds are used in a variety of industries for combustion, drying, catalytic cracking and other processes. However, the process that occurs inside a fluidized bed is extremely complex and — due to a lack of effective measurement techniques —…

Impact of Particle-Size Control on Bulk-Solids Flow Behavior

Crushing and screening of solids are essential to many solids-handling processes, but engineers must be mindful about how those actions will affect flow behavior of the bulk material When it comes to processing bulk solids, (particle) size matters. Almost all…
