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 —…
Low-Carbon Hydrogen: Considering Scale
The future of green hydrogen depends on the success of each stage of its ecosystem. Many factors are contributing to the critical infrastructure scaleup necessary to achieve industrial decarbonization Globally, hydrogen is increasingly being considered as a critical part of…
A photocatalytic platform for CO2 utilization
As more and more CO2 is finding its way into carbon-capture systems instead of the air, the demand for new technologies that actually utilize CO2 is also rising. A new photocatalysis platform developed by New Iridium (Boulder, Colo.; www.newiridium.com) can…
A new class of proton-conducting materials operates at lower temperatures
A new material could open the door to more effective protonic ceramic fuel cells (PCFCs). PCFCs are a promising energy source that employ specialized ceramic materials to conduct protons (instead of electrons) at much lower temperatures than typical solid-oxide fuel…
This photocatalytic reactor system makes chemicals without fossil fuels
Last May, Emerson (St. Louis, Mo.; www.emerson.com) was selected by Syzygy Plasmonics (Houston; www.plasmonics.tech) to automate its all-electric photocatalytic reactor technology. Syzygy has developed, scaled and integrated its core technologies, incubated at, and licensed from, Rice University (Houston; www.rice.edu), into…
Photochemistry boosts the yield of chiral compounds
Isolation and purification of pure, active enantiomers is important in the development of active pharmaceutical ingredients and drug products. However, recovering the desired optical isomer from a racemic mixture means half of the chemical produced — the undesired isomer —…
Commercial debut for a batch reverse-osmosis system
Earlier this year, Salinity Solutions Ltd. (Coventry, U.K.; www.salinitysolutions.co.uk) signed an agreement with Te-Tech Process Solutions (Totton, Southampton, U.K.; www.te-tech.co.uk) to manufacture commercial water-purification systems based on batch reverse-osmosis (RO). This technology, originally characterized and developed at the University of…
Innovations in Mixing Maximize Efficiency
Developments in mixing technologies permit efficient use of energy and resources and manage challenging applications Mixing equipment hadn’t changed much in the past 50 years until recently when chemical processors began demanding more efficiency from their mixing operations due to…
