nanotechnology is a favorite research area that revolutionized mechanical and chemical properties of materials. recently, focusing on concrete as a porous material with micro-scale and nano-scale pores enthusiastic researchers developed their investigations to find out microstructure and mechanical properties of concrete. the aim of this paper is to investigate the effect of nano-silica as an a...

two  simple  protocols  for  the  synthesis  of  1,  2,  4,  5-  tetrasubstitutedimidazoles  using  nano-spa  as  a  reusable,  eco-  friendly,  inexpensive,  and  efficient  catalyst  are  reported.  short   reaction  times,  high  yields,  scale-up  and  easy  workup  are  the   advantages of these protocols.

BACKGROUND Type I interferons (IFNs), including IFN-alpha (IFNA) and IFN-beta (IFNB), have anti-inflammatory properties and are used to treat patients with autoimmune and inflammatory disorders. However, little is known of the role of IFN-tau (IFNT), a type I IFN produced by ruminant animals for inflammation. Because IFNB has recently been shown to inhibit nucleotide-binding oligomerization dom...

Aim: To compare the effect of four different polishing systems on color stability of two Nano composite resins immersed in four beverages (Coffee, Tea, Cola and Fanta). Methods: Eighty disc shaped specimens of 10 mm diameter and 2 mm thickness were prepared for each of the two Nano composite resins (Tetric N Ceram; Estelite alpha). The specimens of each material were divided into four groups (n...

It is widely accepted that deficiency of macro (nitrogen) and micronutrients (zinc, copper etc.) affects the plant growth development which cause a significant threat to crop production food security. The Indian Farmers Fertilizer Cooperative (IFFCO) developed nano-urea (nano-N), nano-zinc (nano-Zn), nano-copper (nano-Cu) liquid fertilizer formulations enhance yields, simultaneously addressing ...

In this study Dodecyl trimethyl ammonium sulphate (DTA) was obtained through quaternization reaction between dodecylamine and dimethyl sulfate (yield: 51.5%) while Dimethylamino propyl glucosylamine (DAPGA) was successively synthesized from D-glucose and 3-Dimethylamino propylamine (yield: 93.6%). Both compounds were analyzed through NMR spectroscopy. Evaluation of their biological activity aga...

A pH-switchable worm system was fabricated by simply mixing two non-surface-active compounds, N-(3-(dimethylamino)propyl)palmitamide (PMA) and citric acid (HCA), at a molar ratio of 3 : 1. Such a nanostructured fluid exhibits bell-shaped sol-gel-sol transitions with sequential pH variation, reflecting continuous structural transformations from sphere to worm to no aggregates.

In order to support the creation of both artificial living organisms in the USA LANL "Protocell Assembly" project and programmable nano-biorobots in the EU "Programmable Artificial Cell Evolution" project, we used quantum mechanical (QM), density functional theory (DFT), the semiempirical PM3 method, and molecular mechanics (MM) software to investigate various complex photosynthetic systems bas...
