to date, the effects of nanoparticles on woody plants remain unaddressed. this study reveals some of the physiological and biochemical effects of sio2 nanoparticles on wild pear seedlings. the seedlings were irrigated with different concentrations of nano silica (0, 10, 100, 500 and 1000 mg/l) for 14 days. nanoparticle adsorption and absorption, biomass allocation, gas exchange, relative water ...

Inexpensive, easy-to-implement coatings exhibiting extremely low reflectance within a broad spectral range, and good adhesion to substrates are in high demand for high-precision optical instruments solar energy harvesting. Herein, we demonstrate highly absorbing coating based on hollow carbon nanospheres (HCSs). The formed via simple high-performing air-spraying process with tailored paint form...

Applications of mica-based pearlescent pigments are related to plastics, cosmetics, automobiles coatings among others, but they seem to be not explored by the ceramic industry. In this work, intensively red and gold colored muscovite pigments covered with layer of nanoparticles containing iron and zirconium oxides were prepared by homogeneous precipitation. The final color was obtained after th...

titanium dioxide is widely used in the manufacturing of paints, varnishes, lacquer, paper, paperboard, printing inks, rubber, floor covering, and ceramics and so on. white titanium dioxide pigment has been produced by two main processes. the sulfate and the chloride processes. each of these two routes requires different feedstocks. however, economic and environmental pressures are shifting the ...

The focus of this study was to improve the Reverse Osmosis Cooling (ROC) process by using CaCO3 for neutralization and selective recovery Fe(OH)3 at pH 3.5. By a specific inhibitor, ferric hydroxide recovered separately from gypsum other metals present in mine water. Ferric processed pigment, product that is imported used as colorant paints tiles. In addition pigment recovery, aluminum calcium ...

Tests were done on the effects of treatments of titanium dioxide spray on corn (Zea mays L.). The study was conducted as a factorial experiment in a randomized complete block design with four replications. Treatments consisted of two factors; the first factor was stage of plant growth that spraying was applied (vegetative stage, appearance of male flowers and female flowers); and the second fac...
