diamondoids are cage-like saturated hydrocarbons consisting of fused cyclohexane rings. thediamondoids family of compounds is one of the best candidates for molecular building blocks (mbbs)in nanotechnology to construct organic nanostructures compared to other mbbs known so far. thechallenge is to find a route for self-assembly of these cage hydrocarbons and their applications in thebottom-up s...

amyloid-β (aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in alzheimer’s disease pathology.uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

self-assembly of densely packed zno nanorods were grown on porous silicon (ps) substrate by low-temperature chemical bath deposition. the structural and optical properties of the obtained zno nanostructures on ps substrate were systematically studied. the strong and sharp (002) peak compared with other peaks in the x-ray diffraction (xrd) indicated thatzno nanorods formed with superior orientat...

riboflavin and protoporphyrin ix are two molecules that participate in oxidation and reduction reactions in the living cell. changing some functional groups of riboflavin and protoporphyrin ix can provide compounds with self-assembled monolayer properties with wide applications in designing the molecular electronic devices. in this study, the amphiphilic structure of riboflavin and protoporphyr...

using of colloids and polymeric microparticles are gradually increasing. it is observed that thepositive effects of particles stems in both traditional applications such as column pickings,coatings and paints to more recent technologies in diagnostics, drug delivery and optical devicesare well documented. this review focuses on importance of colloids and covers theirapplications on three level:...

the corrosion protection abilities of modified copper in 2-[((z)-1-{6-[(2-sulfanylphenyl)ethanimidoyl]-2-pyridyl}ethylidene)  amino]-1-benzenthiol solution containing tio2 nanoparticles were evaluated by tafel  polarization  and  impedance  spectroscopy  in  3.5%  sodium chloride  solution.  the  samples  were  characterized  by  energy dispersive  x-ray  (edx)  and  scanning  electron  microsc...
