BACKGROUND Nanobiotechnology applies the capabilities of biological systems in generating a variety of nano-sized structures. Plants, algae, fungi and bacteria are some systems mediating such reactions. In fungi, the synthesis of melanin is an important strategy for cell-survival under metal-stressed conditions. Yarrowia lipolytica, the biotechnologically significant yeast also produces melanin...

In this work a diffusion-driven inhibitor transport model is used to help in the design of inhibitor-loaded carriers for anticorrosive primers. The focuses on release at damaged locations different dimensions exposed electrolyte and validated experimentally. damage are first simulated determine minimal rate necessary reach required concentrations corrosion protection metal. Kinematic mass conse...

Zn0.9Co0.1O ceramic pigments were synthesized using simple high energy milling method. Zinc and cobalt oxides were used as starting materials. Products were investigated using simultaneous thermal analysis and fourier transformation infrared. Pigments were characterized using X-ray diffraction, diffuse reflectance and Scanning Electron Microscopy. The results showed the effect of calcination te...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

Natural food pigments are commonly utilized for the improvement of the qualitative properties of foods and/or inhibit the development of chronic and degenerative diseases. Several studies have documented the beneficial health effects of natural food pigments, such as anthocyanins, chlorophylls, and carotenoids. These effects mainly depend on the stability, bioactivity, and bioavailability of th...

Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion fouling in ships marine vehicles. Al 2 O 3 CuO nanoparticles were prepared using ball milling process. nano paints these as pigment linseed alkyd resin a binder. Mild-steel specimens coated with paint immersed seawater for 120 days properties studied Scan...

Abstract The research was carried out during the growing season 2021-2022 to find response of two cultivars (Vicia faba L.): Luz De Otono (C1) and symbolized for them by symbols (C2,C1) spraying potassium nano fertilizer (0, 1.2 g/L) symbolizing with (T3.T2,T1), respectively. experiment according a randomized complete block design (R.C.B.D.), studied characteristics leaf area, plant height, chl...
