A solar-powered electrolysis process extracts lithium from seawater
Today, all commercial lithium is sourced from ores or brines on land, where the total lithium reserves amount to 14 million tons. In contrast, the oceans contain 230 billion tons of lithium, although the lithium concentration in seawater is very…
MOF-coated mesh membranes separate oil from water
Current oil-water separation technologies, such as centrifugation, filtration, dissolved air flotation, distillation, oil skinners, adsorption and electrochemical methods, are of low efficiency and consume a lot of energy during complex separation processes. Mesh membranes have attracted much interest lately, and…
Progress toward using ammonia as a hydrogen carrier for fuel cells
In order for ammonia to serve as a hydrogen carrier, it is necessary to develop separation techniques that can reliably recover H2 from the decomposition of NH3 with sufficient purity for operating proton-exchange membrane (PEM) fuel cells. A step in…
Mechanically strong aerogels get closer to commercialization
Aerogels — ultralight, insulating and heat-resistant nanoporous solids — offer benefits in many applications, but commercially available aerogels are typically limited to just two formats: particles and blankets. Aerogel Technologies, LLC (Boston, Mass.; www.aerogeltechnologies.com) is currently constructing a pilot plant…
Carbon-free power: Ammonia synthesized from renewable power and hydrogen
A collaboration between JGC Corp. (JGC, Yokohama, Japan; www.jgc.com), the National Institute of Advanced Industrial Science and Technology (AIST), the National Institute of Technology, Numazu College, and JGC’s subsidiary, JGC Catalysts & Chemicals Ltd., (JGC Group), under the auspices of…
Microwave-plasma platform engineers solid-material properties
A new production process for engineering a range of nano- and microstructured solid materials can reduce the costs of manufacturing the materials compared to conventional “wet-chemistry” approaches, and can allow novel chemistries that are not accessible through traditional methods. Developer…
Gas-solid reaction makes efficient solar cells
The research group of Yabing Qi at Okinawa Institute of Science and Technology (OIST; Japan; https://groups.oist.jp/emssu), in collaboration with Shengzhong Liu at Shaanxi Normal University, China, has developed a simple method to fabricate thin (1µm) perovskite films that can be…
Two new catalysts for continuous-flow synthesis
Shu Kobayashi and colleagues at the University of Tokyo (Japan; www.chem.s.u-tokyo.ac.jp) reported on two new catalysts for synthesizing fine chemicals using their continuous-flow reactor system. The first technology is a novel methodology using CsF.Al2O3 as a highly efficient, environmentally benign,…
Chementator Briefs
O2 recycling A beta field trial has been successfully completed for an adsorption-based technology designed to separate unreacted oxygen in ozone-generating systems. The technology, known as Ozora, was developed by Linde LLC (Bridgewater, N.J.; www.lindeus.com), and was originally launched last…
Water-pollutant-removal technology extended to phosphorus
A project has been announced to demonstrate Microvi’s (Hayward, Calif.; www.microvi.com) pollutant-removal-and-recovery technology for phosphorus in water. The objective of the demonstration is to reduce total phosphorus levels to 0.1 mg/L at a wastewater treatment plant. The nine-month project is…
