Due to their physical properties, nanomechanical sensors (NEMS) can achieve mass measurements in the mega- gigadalton range, which is hardly obtained with conventional mass-spectrometers. However, NEMS signals are subject noise, causing a loss of resolution and thus emphasizing need noise control. We propose denoising model that relies on total variation formulation, deals different models (par...

It is of great significance to understand the underlying mechanism of buckling-driven wrinkles in graphene monolayer due to its applications in nanoelectromechanical systems (NEMS). In previous macroscopic studies based on continuum theory, the chirality-dependent buckling in graphene monolayer is considered as neglectable. However, we found that the growth of buckling-driven wrinkles in graphe...

Size-dependent longitudinal and torsional vibrations of nano-beams are examined by two-phase mixture integral elasticity. A new and efficient elastodynamic model is conceived by convexly combining the local phase with strain- and stress-driven purely nonlocal phases. The proposed stress-driven nonlocal integral mixture leads to well-posed structural problems for any value of the scale parameter...

We generalize a proposal for detecting single-phonon transitions in a single nanoelectromechanical system (NEMS) to include the intrinsic anharmonicity of each mechanical oscillator. In this scheme two NEMS oscillators are coupled via a term quadratic in the amplitude of oscillation for each oscillator. One NEMS oscillator is driven and strongly damped and becomes a transducer for phonon number...

Nanolithography techniques providing a good scalability and feature size controllability are of great importance for the fabrication integrated circuits (IC), MEMS/NEMS, optical devices, nanophotonics, etc. Herein, cost-effective, easy...

Fabrication and readout of devices with progressively smaller size, ultimately down to the molecular scale, is critical for the development of very-high-frequency nanoelectromechanical systems ~NEMS!. Nanomaterials, such as carbon nanotubes or nanowires, offer immense prospects as active elements for these applications. We report the fabrication and measurement of a platinum nanowire resonator,...

the influence of mo particle size on the catalytic activity and product selectivity of alkalized mos2 nanocatalysts has been investigated. nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. three different techniques, including xrd, tem, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

BACKGROUND The National Essential Medicine System (NEMS) is a new policy launched by the Chinese government in 2009. The effects of its introduction have been widely investigated. However, little research has focused on individual patients' perspectives. The purpose of this study was to examine current understanding and opinions of China's NEMS of primary care providers (PCPs) and patients. M...
