Two-dimensional template increases stability of perovskite photovoltaics
Using halide perovskites for photovoltaic (PV) solar-energy cells could dramatically reduce production costs compared to silicon-based PV cells, because perovskites are solution-processible at relatively low temperatures. However, long-term stability of these materials has been a significant challenge. Now, a research…
This electrolysis reactor requires no external electricity source
Electrolyzers are the key technology for producing “green” hydrogen using renewable energy. However, a new reactor platform aims to facilitate electrolysis without the need for any external electricity. The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO), developed by Utility…

Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…
This integrated technology effectively destroys PFAS — even short-chain compounds
The prevalence of the various per- and polyfluoroalkyl substances (PFAS) — compounds that are notoriously difficult to break down — in the water supply is causing global concern. A new partnership between Element Six (Oxford, U.K.; www.e6.com) and Lummus Technology…
Researchers use cellulose nanofibrils in 3D-printed concrete
A research team at the University of Virginia School of Engineering and Applied Science (Charlottesville, Va.; engineering.virginia.edu) is the first to explore how an emerging plant-based material, cellulose nanofibrils, could amplify the benefits of 3D-printed concrete technology. “The improvements we…
Pilot plant produces climate-friendly cement clinker
Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…
New structured packing introduced at Achema
At Achema 2024 (Frankfurt, Germany; June 10–15), Sulzer Chemtech (Winterthur, Switzerland; www.sulzer.com) revealed MellapakEvo (photo), the latest addition to its structured-packing product family. The MellapakEvo structured packing has been developed to enhance the efficiency and capacity of distillation columns, maximizing…
Cyanobacteria mineralize CO2 into biogenic construction materials
Researchers from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS; www.ikts.fraunhofer.de) and the Fraunhofer Institute for Electron Beam and Plasma Technology (FEP; both Dresden, Germany; www.fep.fraunhofer.de) are introducing an eco-friendly, biologically induced method of producing biogenic construction materials as…

Tanning Agent Södra Skogsägarna (Södra; Växjö, Sweden; www.sodra.com) is investing in a production line at Värö that will create a tanning agent from tree bark. This new tannin can be used to process leather in a more environmentally friendly way,…
Versatile production of biopolymers in new semi-crystalline format
Bio-based polymers, such as polyhydroxyalkanoate (PHA), are seeing increasing application as a more sustainable alternative to fossil-based materials. A new, flexible production platform developed by CJ Biomaterials, Inc. (Woburn, Mass.; www.cjbiomaterials.com) is now enabling the production of PHA in both…
