The Myco silver nanoparticles (AgNPs) are synthesized through bio-reduction reaction of silver nitrate by cell-free filtrate of endophytic fungi, which act as both reducing and capping agent. The synthesis of silver nanoparticles (AgNPs) was confirmed through UV-VIS spectroscopy, Fourier Transform Infrared (FTIR), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM). Energ...

Residue of the branch wood camphor tree (Cinnamomum camphora) was used to manufacture binder-free biodegradable biomass fiberboard (bio-board) by wet method. To investigate mechanical properties bio-board, bending rupture stress and tensile tests were measured effect heating temperature applied pressure on performance bio-board evaluated. Scanning electron microscopy (SEM) Fourier transform inf...

Normal and cancerous tissue have changing values of Electrical Impedance Spectroscopy (EIS). In which with comparing their impedance spectrum with bio-impedance measuring system, they can be used for cancerous tissue diagnosis. Probe is the main part in electrical impedance measurement system. In this paper by employing finite element method EIS factor of mucous tissue derived in 5 different pr...

A new type of neutron-scattering spectroscopy is presented that is designed specifically to measure dynamics in bio-systems that are difficult to obtain in any other way. The temporal information is largely model-free and is analogous to relaxation processes measured with dielectric spectroscopy, but provides additional spacial and geometric aspects of the underlying dynamics. Numerical simulat...

A family of silica-supported, magnetite nanoparticle catalysts was synthesised and investigated for continuous-flow acetic acid ketonisation as a model pyrolysis bio-oil upgrading reaction. The physico-chemical properties of Fe3O4/SiO2 catalysts were characterised by using high-resolution transmission electron microscopy, X-ray absorption spectroscopy, X-ray photo-electron spectroscopy, diffuse...
