Some studies have proven the antioxidant and antimicrobial potency of chestnut flowers both in the raw matrix and after extraction, and the consumption of their decoctions has been related to beneficial effects towards health. In recent years, due to controversy and ambiguous legislation of chemical conservatives, plant extracts have been successfully used as functionalizing agents in different...

The combination of 1-benzyl-1,4-dihydropyridines with the strong Lewis acid, B(C6F5)3, generates a stable pyridinium borohydride species in high yields (94%) in as little as 10 min. This use of biologically inspired hydride sources further builds on the recent work of new hydride donors in the formation of borohydrides. When functionalizing the dihydropyridine with an amide or carboxylic acid m...

The new anti-cancer and water-soluble curcumin derivatives have been synthesized solvent-freely by functionalizing the phenolic group of with various NH compounds to increase water solubility cancerous properties. biological applications drugs investigated against highly potent HepG2 carcinoma cell line. studies showed that could be used in low concentrations (µM/l<1) avoid anti-apoptoti...

Now a day study on boron nitrid nanotubes are in considerable attetion due to their unique properties in different field of science. In this letter, after final optimization, thermodynamic properties analysis, stabilities, electronic structure and nuclear magnetic resonance parameters including σ isotropic and σ anisotropic tensors and asymmetric parameters of 15N and 11B nuclei are calculated....

There are two categories in the graphene preparations which top-down and bottom-up methods. Top-down methods consist of mechanical exfoliation, chemical exfoliation synthesis reduction. Meanwhile, vapor deposition (CVD), pyrolysis epitaxial growth under Graphene has its own limitation unsuitable for certain applications. Thus, functionalizing with selected molecules nanomaterials may result fun...

A method is presented to indirectly measure and shorten carbon nantoubes grown from the tips of atomic force microscope (AFM) probes. The measurement component exploits the nanotubes ability to elastically buckle and requires only those signals and actuators available on a standard AFM. The shortening operation is facilitated by electric arcing using a conducting niobium substrate. The shorteni...
