in this investigation, hydroxyapatite (hap) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow-size distribution in diameter has been synthesized successfully by low-temperature hydrothermal process, and the as-synthesized powders were characterized by energy-dispersive x-ray spectroscopy, scanning electron microscopy, high-resolution transmission electron mi...

Single-mode, air-cladded optical waveguides have wavelength scale diameters, making them very fragile and difficult to handle yet highly desirable for sensing inter-chip photonic interconnects. These contradictory qualities are resolved in this work by supporting the waveguide with a nano-fin structure attached substrate, narrow enough sufficiently tall minimally impact wave-guiding metrics of ...

Government regulations to address technological risks are important for the successful development and application of nanotechnology, but there is an ongoing debate in the USA about who is responsible for the regulation of nanotechnology. In a mail survey of leading US nano-scientists, we examine scientists’ perceptions about nano-regulation, including the government level (local, national, or ...

Abstract The growth of responsible innovation (RI) scholarship has been mirrored by a proliferation RI definitions and practices, as well recognition the importance context for RI. This study investigates how researchers in field nanotechnology food agriculture (nano-agrifoods) define practice RI, what motivations they see pursuing We conducted 20 semi-structured interviews with nano-agrifood f...

In the last decade, developments in nanotechnology have provided a new field in medicine called “Nanomedicine”. Nanomedicine has provided new tools for photodynamic therapy. Quantum dots (QDs) are approximately spherical nanoparticles that have attracted broad attention and have been used in nanomedicine applications. QDs have high molar extinction coefficients and photoluminescence quantum yie...

Diamond/graphene composite three-dimensional electrode has attracted extensive attention because of its low background current, wide potential window from diamond component, and high electrochemical activity graphite component. In this work, by using the hot wire chemical vapor deposition method, nano diamonds are embedded in vertical graphene sheet on surface single particle layer regulating s...
