We report on a black metamaterial of gold fabricated on a lotus leaf that was used as a template. In spite of the extremely thin gold coating (10-nm thick) on the lotus leaf, the surface shows reflectivity below 0.01 over the entire visible spectral range. Finite-difference time-domain (FDTD) calculations suggest that the low reflectivity stems from the secondary structures on the lotus leaf, w...
Here we present the first successful attempt to programme the surface properties of nanostructured soft biological tissues by atomic layer deposition (ALD). The nanopatterned surface of lotus leaf was tuned by 3-125 nm TiO2 thin films. The lotus/TiO2 composites were studied by SEM-EDX, XPS, Raman, TG-DTA, XRR, water contact angle and photocatalysis measurements. While we could preserve the supe...
Since the first studies published in the fifties and sixties (Nakaoki et al., 1956; Harney and Grant, 1964; Bate-Smith, 1965), many authors have investigated the flavonoid chemistry of Lotus corniculatus (Table 1 and Table 2) and demonstrated the richness and diversity of flavonoid compounds in this species. Some authors have examined the variation with altitude of the flavonoid content of Lotu...
زیتون یکی از مهمترین محصولات باغی در گلستان است که نقش مهمی را در اقتصاد این استان ایفا می کند. برای بدست آوردن حداکثر بهره وری کمی و کیفی این محصول، آزمایشی بهصورت فاکتوریل در قالب طرح بلوک<span style="font-size: 11.0pt; font-family: ...
Lotus species are forage legumes with potential as pastures in low-fertility and environmentally constrained soils, owing to their high persistence and yield under those conditions. The aim of this work was the characterization of phenetic and genetic diversity of salt-tolerant bacteria able to establish efficient symbiosis with Lotus spp. A total of 180 isolates able to nodulate Lotus cornicul...
