Delivering functional substances across the cell membrane barriers has been a great challenge in biomedicine. Among various strategies to improve cellular uptake, DNA nanostructures, with different shapes and sizes, supply as suitable platforms for delivering wide range of cells. With programmability, biocompatibility, biostability, nanostructure-based delivery systems have shown succeeded anti...

Nanotechnology and nanomaterials have a promised future in different aspects of modern life that involve medicine, environment, space, energy, electronics, security, and many others. While the applications of nanomaterials seem to be limitless, new challenges are also being posed. With regard to the type of one-dimensional nanostructure of Cadmium Selenide (CdSe), there are three possible morph...

Metasurfaces able to concentrate light at various wavelengths are promising for enhancing nonlinear interactions. In this Letter, we experimentally demonstrate infrared second-harmonic generation (SHG) by a multi-resonant nanostructure. A 100 GaAs layer embedded in metal-insulator-metal waveguide is shown support localized resonances. One resonance enhances the polarization due transverse magne...

The insertion of a synthetic amphiphilic, α-helical peptide into a supported hybrid bilayer membrane (HBM) was studied by neutron reflectometry to elucidate the resulting nanostructure. The HBM consisted of a self-assembled monolayer of perdeuterated octadecanethiol on gold and an overlying leaflet of acyl-deuterated phosphatidylcholine (d-DMPC). Using contrast variation, several reflectivity s...

Mechanical stress is increasingly applied in microelectronics. For instance, strained silicon technology is widely used to improve carrier mobility and then driver current for advanced MOS transistors. For microelectromechanical systems, piezoresistive effects are universally employed in pressure sensors. In this paper, we present an original method for studying mechanical stress impact on the ...

the pomegranate juice with high nutritional value has turbid appearance that makes it difficult to preserve and concentrate. microfiltration is useful process which can clarify it. one of the most important problems in this process is fouling phenomenon which affected by several parameters. the effects of fluid velocity, transmembrane pressure, membrane type and its pore size on membrane foulin...

Microparticles (MPs) are sub-micron membrane vesicles (100-1000 nm) shed from normal and pathologic cells due to stimulation or apoptosis. MPs can be found in the peripheral blood circulation of healthy individuals, whereas elevated concentrations are found in pregnancy and in a variety of diseases. Also, MPs participate in physiological processes, e.g., coagulation, inflammation, and angiogene...

This research addresses the extraction and recovery of nickel ions from real electroplating wastewater using SLM process. The process involves three main phase system which are feed, organic and stripping phase. The feed phase containing the nickel electroplating wastewater whereas the organic phase containing the liquid membrane which was immobilized in the membrane support. The liquid membran...
