encapsulation of bioactive ingredient and production of nano carriers in order to food enrichment and production of functional food is one of the applications of nano technology in food science and pharmaceutical. nano carriers are produced using biopolymers (proteins and polysaccharids) or lipid based materials. in this research, production and characterization of pectin-casein nanocomplexes a...

In this paper, antineoplastic activities of protein-conjugated silver sulfide nano-crystals with different shapes were described in detail. Transmission electron microscope analysis demonstrated that stable and well-disperse protein-conjugated silver sulfide nano-particles, nano-rods, and nano-wires could be prepared by aqueous chemistry method. The Fourier transform infrared spectrograph analy...

We report a new demonstration of nanoscale solution-processed photodetectors by fabricating a nano-sized gap between two electrodes and drop-casting nanocrystal quantum dots (NCQDs) into the gap. We demonstrate a detection sensitivity of 62 pW with a max responsivity of 2.7 mA/W over a device with a nano-gap of 25 nm. Additionally, we characterize the dependence of signal-to-dark current ratio ...

Advancement in the field of nanotechnology and its applications to the field of medicines and pharmaceuticals has revolutionized the twentieth century. Nanotechnology [1] is the study of extremely small structures. The prefix “nano” is a Greek word which means “dwarf ”. The word “nano” means very small or miniature size. Nanotechnology is the treatment of individual atoms, molecules, or compoun...

Nano-dispersions of perfluorocarbon (PFC) or PFC emulsions are substitutes of erythrocytes. They perform the function of the gas transport on condition when the particle structure will be preserved. The invariable values of the size and surface properties of the spherical PFC particles characterize the stability of their structure. The stable nano-dispersion on base PFC and phospholipids (PL) a...

OBJECTIVE To discuss the influences of the concentrations of sodium cholate, cholesterol and drug, preparation temperature, ultrasonic time and power on the particle size and encapsulation efficiency of Flos Magnoliae volatile oil nano-liposome through film-ultrasonic wave technique together with membrane filter method. METHODS The nano-liposomes were prepared by film-ultrasonic wave techniqu...

Density functional theory (DFT) was used to understand the shock sensitivity on the properties of high energy density materials (HEDMs) using 1-(2-nitro2-azapropyl)-5H-tetrazole as a test molecule due to its small size and similar explosive properties to more common explosive compounds such as hexahydro-1,3,5-trinitro1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetraazocine (HMX)....

The effects of two common binders (BR and F binder) on the thermal decomposition HMX molecules during linear heating were studied by molecular dynamics simulation. It was found that both can induce reaction earlier, promote conversion intermediate products to stable products, reduce activation energy potential barrier system. induction binder in composite system makes initial appear at interfac...
