The transport of nanoparticles (NPs) in polymer networks, as a typical simplified model describing various structures living systems, is profoundly important biomedical engineering and nanotechnology. Predicting the effective diffusivity an NP confined ordered network has been intriguing focus this frontier field. In present study, diffusion NPs unentangled for different radii stiffnesses numer...

We studied the spectral diffusion and exciton fine structures of single-walled carbon nanotubes (SWNTs) using single carbon nanotube spectroscopy. Two types of single nanotube photoluminescence (PL) spectra were observed at temperatures below 50 K, double peaks with spectral diffusion and a single peak without spectral diffusion. The spectral diffusion occurring in the lower energy peak of the ...

Double-diffusive convection, in which a fluid is acted upon by two fields (such as temperature and salinity) that affect the density, has been widely studied areas diverse oceans stellar atmospheres. Assuming classical Fickian diffusion for both heat salt, evolution of salinity are governed parabolic advection–diffusion equations. In reality, there small extra terms these equations render hyper...

A method was developed for identification of Bacillus anthracis based on elaboration of protective antigen by individual colonies and its detection by double-diffusion precipitation in agar plates.
