This work presents a strategy for the mesoscopic engineering of hierarchically structured sodium alginate (SA) aerogels to enhance macroscopic performance. The was implemented by meso-functionalizing and reorganizing SA via controlled heterogeneous nucleation, in which microcrystalline cellulose-manganese dioxide (MCC-MnO 2 ) nano-crystallites worked as template. Due short rod-like structure ab...

Abstract Growth of bionanotechnology requires functional materials, which can lower the costs and be modified to specific reaction. Conjugations nanoparticles enzymes form efficient products multi-material enzyme-nanocomplexes, controlled from synthesis application provide predicted results. Multimetallic nanooxides ZnO–CuO, ZnO–MnO, ZnO–MnO–CuO were obtained by precipitation method with sonica...

Pyrolusite (β-MnO 2 ) was investigated for potential use in energy storage devices due to its promising properties cathode materials rechargeable lithium-ion batteries. A combination of evolutionary algorithm search techniques and density functional theory were used determine the structural stabilities β-MnO nanoclusters on landscape. However, pyrolusite suffers from some defects impurities tha...

The relative energetic stability of the structural phases common antiferromagnetic transition-metal oxides (MnO, FeO, CoO, and NiO) within semilocal hybrid density functionals are fraught with difficulties. In particular, MnO is known to be most difficult case for almost all approximations. Here, we show that meta-generalized gradient approximation (meta-GGA) constructed from cuspless hydrogen ...

Silver/manganese dioxide (Ag@MnO 2 ) nanorods are synthesized and characterized by scanning electron microscopy, transmission energy dispersive X-ray spectroscopy, powder diffraction, photoelectron spectroscopy. It was discovered that Ag@MnO can realize hydrogen-borrowing reactions in high yields also effective for the synthesis of tert-butyl esters from aryl cyanides hydroperoxide a short peri...

We have investigated nearly monodispersive MnO nanoparticles of 10 nm diameter by polarised neutron diffraction with XYZ-polarisation analysis. We found no long-range ordering down to 3.5K. A broad magnetic peak appeared close to Q1⁄4 (1/2,1/2,1/2) signifying short-range antiferromagnetic correlations. The correlation length was found to be about 2.4 nm at T1⁄43.5 K. The correlation length decr...
