By acetylene pyrolysis at 650 and 5508C, carbon nanotubes were synthesized successfully in porous alumina templates anodized in sulfuric and/or oxalic acid solution. For templates anodized in oxalic acid followed by boiling in distilled water, thermal decomposition of acetylene at 6508C in the pores results in the formation of carbon nanofibres. For templates anodized in sulfuric acid, only car...

A strain of the common mushroom Agaricus campestris was grown on a mixture of composted sawdust and CaCO(3). On incubation for 47 days, the organism produced 20.5 g of oxalic acid per 100 g of initial dry compost solids.

Recently hierarchical architectures, consisting of two-dimensional (2D) nanostructures, are of great interest for potential applications in energy and environmental. Here, novel rose-like WO₃ hierarchical architectures were successfully synthesized via a facile hydrothermal method. The as-prepared WO₃ hierarchical architectures were in fact assembled by numerous nanosheets with an average thick...
