Abstract In this review, we engineer a high-performing nanosensor mechanic based on SPPs, which consists of metal-insulator-metal waveguide coupled with two triangular plates in double-internal-pile ring cavity (DISRC). The feasibility establishing the sensor SPPs is analyzed theoretically, and parameters DISRC are simulated by finite element method. best sensitivity proposed system 2640 nm/RIU...

We develop a spectral representation formalism to calculate the Casimir force, in the non-retarded limit, or van der Waals force between a spherical particle and a substrate, both with arbitrary local dielectric properties. The spectral formalism allows to study the system as a function of its geometrical properties separately from its dielectric properties. The calculated force is attractive, ...

The (nine) valid species of Japanagallia Ishihara, 1955 from Guizhou, and Yunnan Provinces, and Guangxi Autonomous Region of Southwest China are reviewed and four new species J. gracilenta sp. nov., J. neohamata sp. nov., J. trifurcata sp. nov. and J. viraktamathi sp. nov. are described and illustrated. These species can be distinguished by unique features of the aedeagus. J. hamata Zhang & Li,...

Morphine and tramadol which have analgesic effects can be administered acutely or chronically. This study tried to investigate the effect of these drugs at various times by using different methods of administration (intraperitoneal, oral, acute and chronic). Sixty adult female rats were divided into six groups. They received saline, morphine or tramadol (20 to 125 mg/Kg) daily for 15 days. A ho...

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 ...

Avec la dissémination des dispositifs portables (smartphones, tablets, nano-ordinateurs, etc.) et leur augmentation en puissance de calcul, il est devenu essentiel de mettre en place une plate-forme pour la coordination des dispositifs et la gestion de leurs informations. Afin de garantir l’efficacité et le passage à l’échelle dans des environnements tels que l’Internet of Things (IoT), nous de...

Currently, cylindrical beams with radial or azimuthal polarization are being used successfully for the optical manipulation of micro- and nano-particles as well as in microscopy, lithography, nonlinear optics, materials processing, and telecommunication applications. The creation of these laser beams is carried out using segmented polarizing plates, subwavelength gratings, interference, or ligh...

Recent measurements suggest the possibility to exploit ionic liquids (ILs) as smart lubricants for nano-contacts, tuning their tribological and rheological properties by charging the sliding interfaces. Following our earlier theoretical study of charging effects on nanoscale confinement and squeezout of a model IL, we present here molecular dynamics simulations of the frictional and lubrication...
