multiwall carbon nanotubes (mwcnts) are grown via chemical vapour deposition method directly on a stainless steel substrate. raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. after their removal from the stainless steel substrate, the as-grown mwcnts are then a...

The characteristics of microhabitats in streams can drive the distribution tadpoles. We experimentally examined microhabitat selection tadpoles Dryophytes plicatus . used a series choice experiments to test if had preferences for particular substrate types, colors, and vegetation. Tadpoles D. strong preference mud substrates over sand, gravel, rock preferred darker lighter substrates. non-veget...

In this study, tungsten oxide and vanadium oxide electrochromic thin films were placed in vacuum and in a thickness of 200 nm on a transparent conductive substrate of SnO2:F using the physical method of thermal evaporation. Then they were studied for the optical characteristics in the wavelength range from 400 to 700 nm and for their electrical potentials in the range form +1.5 to -1.5 volts. T...

In the present study, packaging of a greenhouse-grown tomato on the culture medium containing 0, 25, 50, 75 and 100% compost tea under modified atmosphere: MA (88%N2 + 8%CO2 + 4%O2) in polyethylene and nanosilicon-polyethylene bags was studied at 5°C for 30 days. Several quality parameters such as moisture content, pH, total soluble solids (TSS), titratable acidity (TA), Vitamin C content, text...

The  inhibition effects seed and peel of melon on diphenolase activity of mashroom tyrosinase were investigated. The IC50 values and Ki values of seed and peel of melon were evaluated. increased the Km value and decreased the Vm value so it show mixed type inhibition on mushroom tyrosinase when L-DOPA was used as a substrate.
