We present a novel method for investigating a nanometric cluster of water molecules, which includes the formation and manipulation of nanometric water, and the measurement of its mechanical properties. The atomic force microscope based on the quartz tuning-fork sensor is employed to form and manipulate the nanometric water, and the theoretical tool of amplitude-modulation atomic force microscop...

The micro/nano motion stage with ultra-high precision are urgently required to perform such tasks as operation under scanning probe, bio-cell manipulation, optical fibers alighment, etc. The compliant XY micro manipulator employing flexure hinges is widely applying due to their excellent characteristics of simple structure, no backlash, no nonlinear friction, and so on [1]. Some novel compliant...

Current optical approaches are progressing far beyond the scope of monitoring the structure and function of living matter, and they are becoming widely recognized as extremely precise, minimally-invasive, contact-free handling tools. Laser manipulation of living tissues, single cells, or even single-molecules is becoming a well-established methodology, thus founding the onset of new experimenta...

We report on the fabrication and operation of a multi-element vibrational structure consisting of two graphene mechanical resonators coupled by a nanotube beam. The whole structure is suspended. Each graphene resonator is clamped by two metal electrodes. The structure is fabricated using a combination of electron-beam lithography and atomic-force microscopy nano-manipulation. This layout allows...

The implementation of nuclear magnetic resonance (NMR) at the nanoscale is a major challenge, as the resolution of conventional methods is limited to mesoscopic scales. Approaches based on quantum spin probes, such as the nitrogen-vacancy (NV) centre in diamond, have achieved nano-NMR under ambient conditions. However, the measurement protocols require application of complex microwave pulse seq...

Quantum state manipulation has become a fascinating perspective of modern physics. With concepts developed in atomic and molecular physics the field has been further stimulated by the possibility of quantum computation. For this purpose a number of individual two-state quantum systems (qubits) should be manipulated in a controlled way. Several physical realizations of qubits have been considere...

Objective: There is a large theoretical literature regarding stock market manipulation. However, empirical evidence of manipulation remains scare especially in emerging markets like Iran. So, it is vital to detect and prevent. Manipulation distorts prices, thereby reducing market efficiency and harms public confidence. Distorted prices increase market volatility and risk. This study empirically...

A nano-optical conveyor belt is a unique type of near-field optical tweezer, capable not only capturing nanoparticles, but also transporting them. In this study, we propose multichannel conveyer, based on simple rectangular distributed grating array. The design was optimized by varying the number slits in gratings, and particle transport achieved adjusting phase difference excitation beams. Sim...

Identification of major histocompatibility complex (MHC)-associated peptides recognized by T-lymphocytes is a crucial prerequisite for the detection and manipulation of specific immune responses in cancer, viral infections, and autoimmune diseases. Unfortunately immunogenic peptides are less abundant species present in highly complex mixtures of MHC-extracted material. Most peptide identificati...

The mechanical properties of materials are inherently multiscale, depending on phenomena at all length scales. Hence, multiscale modeling is a huge scientific challenge as well as a critical necessity for successful manipulation of material properties. This proposed research aims to investigate the microstructure (i.e., grain and inclusion) effect on the material properties especially for the s...
