A new mobile biochar production unit capable of turning forestry residues and invasive weeds into a useful soil product is being trialled in by the NSW Department of Primary Industries and Regional Development (DPIRD) in northern NSW, with researchers investigating…
We've all heard the story: biochar cleans water by adsorbing pollutants -- trapping them like a sponge. Or, in fancier setups, it acts as a catalyst to help oxidants like hydrogen peroxide break down toxins. But Dr. Gao's team asked a…
Adjusting the nitrogen-to-boron ratio in sawdust-derived biochar boosted sulfamethoxazole degradation rates 2.35-fold by shifting the material from adsorption-driven to catalysis-driven pollutant removal. Subject of Research: Nitrogen and boron co-doped biochar catalysts for peroxymonosulfate activation and antibiotic degradation in water
A magnetically recoverable fungal biomass composite modified with copper ferrite nanoparticles and the MOF ZIF-67 removed up to 99.17 percent of cadmium from synthetic solutions and 70.2 to 82.6 percent from real industrial wastewaters.
KOH-activated biochar made from Pinus roxburghii pinecones removed up to 83.59 percent of Mn(II) from water under statistically optimized conditions of pH 8.0, 5 g/L dosage, 229.4 rpm stirring, and 45.6 minutes of contact time. Pinecone Biochar Strips Manganese From Water at 83.59% Efficiency The…
Kinetic modeling of the adsorption data pointed to a specific mechanism. The pseudo-second-order kinetic model predicted the results well, with a coefficient of determination of 0.99926, indicating that surface-mediated interactions are crucial to the adsorption process. On the basis of these…
Graphite is designated as a critical mineral by the U.S. Government due to its essential role in modern technology and its vulnerability to supply chain disruption. To evaluate domestic graphite resources, the U.S. Geological Survey (USGS) conducted two airborne electromagnetic (AEM) surveys…
Researchers created multiphase strontium, magnesium, and barium oxide-carbon nanocomposites that adsorb malachite green with capacities up to 371.75 mg/g and remain reusable over five regeneration cycles.
Researchers created diamondiyne, an experimentally confirmed three-dimensional carbon allotrope whose tetrahedral framework forms a porous structure resembling diamond. Researchers at the University of Gothenburg have created diamondiyne, a new carbon allotrope with a three-dimensional structure that the team describes as…
Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to…
Carbon nanotubes, carbon fibre, biochar, activated carbon, graphite, diamond and other forms of carbon studied and made as materials.
