Flower-like gold nanoparticles (Au-NPs) were fabricated in surfactant-PMo(12) hybrid assemblies, where PMo(12) served as a UV-switchable reducing agent for producing Au-NPs and the organic surfactant matrices played the role of a soft template for the formation of flower-like structure of Au-NPs.

There is substantial diversity in Achillea biebersteinii plants in Iran. It has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. Research improvement for medicinal plants depends on the available genetic diversity. The assessment of genetic variability could increase the information for breeding programs. ...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

Let G be a (p, q) graph. Let f : V (G) → {1, 2, . . . , k} be a map. For each edge uv, assign the label gcd (f(u), f(v)). f is called k-prime cordial labeling of G if |vf (i) − vf (j)| ≤ 1, i, j ∈ {1, 2, . . . , k} and |ef (0) − ef (1)| ≤ 1 where vf (x) denotes the number of vertices labeled with x, ef (1) and ef (0) respectively denote the number of edges labeled with 1 and not labeled with 1....

Two factorial experiments were conducted to study the interactive effects of four levels of sucrose (0, 20, 40 and 60 g l-1), two levels of citric acid (0 and 160 mg l-1) and two levels of one of the following compounds (aluminum sulphate, 0 and 160 mg l-1 and silver nitrate, 0 and 120 g l-1) on vase life and quality attributes of lisianthus cut flowers ‘Mariachi blue fonce.’ The experiments ca...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...

A three dimensional (3D) hierarchical silver supported tungsten oxide flower-like microsphere catalyst has been fabricated using a cationic surfactant CTAB. It was found that the crystal-splitting mechanism plays a key role in the formation of this flower-like structure. This catalyst was proved to be highly effective in the liquid phase selective oxidation of m-xylene to isophthalic acid.

The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

Flower induction in apple (Malus domestica Borkh.) trees plays an important life cycle role, but young trees produce fewer and inferior quality flower buds. Therefore, shoot bending has become an important cultural practice, significantly promoting the capacity to develop more flower buds during the growing seasons. Additionally, microRNAs (miRNAs) play essential roles in plant growth, flower i...
