in this paper, the concept of {sl local base with  stratifiedstructure} in $i$-topological vector spaces is introduced. weprove that every $i$-topological vector space has a balanced localbase with stratified structure. furthermore, a newcharacterization of $i$-topological vector spaces by means of thelocal base with stratified structure is given.

in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...

in this paper, plate-like nio nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (ii) schiff base complex as new precursor. first, the nickel (ii) schiff base precursor was prepared by solid-state grinding using nickel (ii) nitrate hexahydrate, ni(no3)2∙6h2o, and the schiff base ligand n,n′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

Zn-Al layered double hydroxide (LDH) nanoparticles with carbonate as the charge balancing anion in the interlayer space were synthesized using co-precipitation method. Then, the carbonate base Zn-Al LDH nanoparticles were doped with phosphate ion via anion-exchange reaction to synthesize Zn-Al-[PO43-]-[CO32-]. The structure and composition were characterized by X-ray diffraction (XRD), Fourier ...

The continued desire to utilize an alternative to leadbased solder materials for electrical interconnections has led to significant research interest in Anisotropic Conductive Adhesives (ACAs). The use of ACAs in electrical connections creates bonds using a combination of metal particles and epoxies to replace solder. The novel ACA discussed in this paper allows for bonds to be created through ...

in recent decade, the new advanced nanofluids, composed from various particles, have attracted the attention of researchers. this class of nanofluids, which can be prepared by suspending several types (two or more than two) of nanoparticles in base fluid, is termed as hybrid nanofluids. in this work, an experimental investigation on the effects of temperature and concentration of nanoparticles ...

Base excision repair of genotoxic nucleobase lesions in the genome is critically dependent upon the ability of DNA glycosylases to locate rare sites of damage embedded in a vast excess of undamaged DNA, using only thermal energy to fuel the search process. Considerable interest surrounds the question of how DNA glycosylases translocate efficiently along DNA while maintaining their vigilance for...

The term Nanofluids was first coined by Sir Stephen Choi in 1995 at Argonne National Laboratory ,U.S.A .Since the discovery, nanofluid have been explored as heat transfer fluids. Nanofluids increased the thermal conductivity of existing coolants (Water, Ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .From 1995 till 2008 nano...
