Nano size nickel copper ferrite powders (NiCuFe2O4) have been prepared by a prepared by Co precipitation method. The resulting powders were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM).The result showed nanosize nickel copper ferrite(35.65nm). The powders showed extensive XRD line broadening and sizes of crystals observed from the XRD line broadening was35.65 nm,...

Nanopore technology has been developed for detecting properties of proteins through monitoring of ionic current modulations as protein passes via a nanosize pore. As a real-time, sensitive, selective and stable technology, biological nanopores are of widespread concern. Here, we introduce the background of nanopore researches in the area of α-hemolysin (α-HL) nanopores in protein conformation d...

The behavior of a thin-film GeTe crystal induced by intense femtosecond laser pulses ( $$\lambda = 0.8{\kern 1pt} $$ μm) has been studied using pulsed electron diffractometer. sample is an annealed 20-nm film on copper grid with carbon coating. It found that ablation results in the formation ultrathin (assumingly, monolayer) high radiation resistance. Possible reasons for detected nanosize effe...

Nanosized Pb junctions exhibit superconducting correlations at magnetic fields more than an order of magnitude higher than the zero-temperature critical field of the bulk Pb. The strongly enhanced critical field is a spectacular demonstration of nanosize effect where the Meissner screening currents become ineffective for junction’s tip smaller than the London penetration depth (32 nm for Pb). F...

The objective of this research is to test the hypothesis that power generation in a nanoscale-gap thermophotovoltaic (TPV) device can be enhanced by a factor of 20 to 30, compared to conventional TPV systems, due to radiation heat transfer exceeding the blackbody limit. This hypothesis will be tested by measuring radiative heat fluxes and TPV performances in an experimental apparatus involving ...

Traditional nanostructured design of cerium oxide catalysts typically focuses on their shape, size, and elemental composition. We report a different approach to enhance the catalytic activity of cerium oxide nanostructures through engineering high density of oxygen vacancy defects in these catalysts without dopants. The defect engineering was accomplished by a low pressure thermal activation pr...

Risks of harm, translational uncertainty, ambiguities in potential direct benefit, and long-term follow-up merit consideration in first-in-human research. Some nanomedical technologies have additional characteristics that should be addressed, including: defining and describing nanomedical interventions; bystander risks; the therapeutic misconception; and a decision-making context that includes ...

We investigated the existence of nanosize particles in synovial fluids of rheumatoid arthritis and osteoarthritis patients. These specimens were cultured under mammalian cell culture conditions (37 degrees C; 5% CO2/95% air) for a long period. After about 2 months, many nanoparticles appeared and they gradually increased in number and in size. The nanobacteria-like particles exist in synovial f...

INTRODUCTION Interactions of the ceria particles with polyurethane surfaces are of great interest for polishing processes used in modern semiconductor industry. Specifically, ceria abrasive nanoparticles and polyurethane polishing pads are now broadly used in the process called Chemical-Mechanical Planarization/Polishing (CMP) [1,2,3]. To optimize the process of CMP, various chemicals, abrasive...
