Nanostructure of Interfaces and Giant Magnetoresistance of Co/Cu Superlattices

Chuprakov S.A., Verhovsky S.V., Krinitsina T.P., Bannikova N.S., Blinov I.V., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

The structure, the state of interfaces and magnetoresistance of [Co(1.5nm)/Cu(0.9nm)]n superlattices have been studied. The magnetoresistance decreases with the growth of n from 38% for n = 10 to 24% for n = 40. TEM [...]

Nanopatterned coatings for advanced glass products

McMackin I., Geddes J., Aryal M., Seitz O., Kobrin B., Rolith, Inc., US

A wide variety of glass products would greatly benefit from coatings that offer anti-reflective, anti-glare, anti-fog, anti-ice, self-cleaning, and other advanced functions. State-of-the-art coatings do not meet desired performance characteristics or cannot be applied over [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]

Spirofluoreneacridinone-Based Shape-Controlled Nanorods for Aqueous Phase Processing Light-Emitting Devices

Lin Z-Q, Liang J., Xie L-H, Huang W., Nanjing University of Posts & Telecommunications, CN

The unique cruciform-shaped spirocyclic aromatic hydrocarbons might provide a facile strategy to design the multi-dimensional nanostructure of organic semiconductors “bottom up”, which could be exploited as the building block for micro/nano optoelectronic devices. Over the [...]

A Novel Technique for Depositing Vertically Aligned Molybdenum Oxide Nanoplates

Sharma R.K., Reddy G.B., Indian Institute of Technology Delhi, IN

Single crystalline, vertically aligned nanoplates of molybdenum trioxide (MoO3) were grown on the cobalt coated glass substrates by a simple sublimation process in the presence of oxygen plasma. Many research groups have reported the synthesis [...]

An explosive impact technique to nanocrystallize and harden surface of metal materials

Tong S.J., Tong Z., Shi Z.M., Tong S.J., Tong Z., Inner Mongoli University of Technology, CN

An explosive impact surface nanorisation technique (EISNT) was developed to prepare nanostructured surface layers on medium carbon steel (MCS) and pure Copper (PC) plates. The plastic deformation involved the entire plate depth of 4-6 mm, [...]

C-AFM as a means to identify heterogeneities at the nanoscale in thin anodic TiO2 films

Diamanti M.V., Souier T., Chiesa M., Pedeferri MP., Politecnico di Milano, IT

The anodic oxidation of titanium allows the obtaining of an oxide layer with thickness, color, homogeneity and insulating properties that depend on the process parameters. TiO2 thin films have been studied mostly to derive information [...]

Exchange Bias Formation Mechanism in (110)Al2O3/Py/Mn/Ta Nanostructures

Blinov I.V., Krinitsina T.P., Matveev S.A., Milyaev M.A., Popov V.V., Ustinov V.V., Institute of Metal Physics, RU

Magnetic multilayer nanostructures possessing exchange bias are of interest for spintronics as effective magnetic field sensors. The mechanism and conditions of the exchange bias formation in (110) Al2O3/Py(30nm)/Mn(100nm)/ Ta(10nm) nanostructures at thermal-magnetic treatment have been [...]

Solution Growth of Nanostructured Ceramic Films

Cho J., State Univ of New York (SUNY) at Binghamton, US

Low-temperature processing that can lead to the development of highly-functional, strain-tolerant ceramic films will offer innovative solutions for the use of ceramic thin films and coatings. Current developments in organic and flexible electronics make the [...]

Platinum Bowtie Nanostructure Arrays for Massively Parallel Single Molecule Detection Based on Fluorescence Enhancement Phenomena

Saito T., Takahashi S., Obara T., Itabashi N., Imai K., Hitachi High-Technologies Corporation, JP

To enable not only long sequence read but also high throughput in a DNA sequencer, the single molecule sequencing method based on direct observation of processive DNA polymerization is very promising. In this method, only [...]
