A double-tapered optical fiber tweezers (DOFTs) was fabricated by a chemical etching called interfacial layer etching. In this method, the second taper angle (STA) of DOFTs can be controlled easily time. Application to trapping yeast cells presented. Effects STA on axile efficiency and position were investigated experimentally theoretically. The experimental results are good agreement with theoretical ones. demonstrated that non-contact capture realized for large (e.g. 90 deg) there an...
Abstract The nickel cobalt ammonium phosphate (NH 4 (Ni, Co)PO )/carbon fibers (CFs) electrode materials were prepared by a hydrothermal method. nanoflower‐like active ) have an average particle size of about 500 nm, which are uniformly and tightly dispersed on the surface CFs. specific capacitance composite NCCF‐3 with molar ratio Co Ni 1:1 is as high 811.1 F·g −1 at current density 1.25 A·g . Meanwhile, electrochemical performance exhibits good reversibility batter stability 89.1%...
To evaluate the efficacy of bone strengthening and pain relieving capsules in treatment postmenopausal osteoporosis its correlation with AMPK/mTOR autophagy signaling pathway.
Electrical and chemical bonding properties of P-doped ZnO thin films grown by pulsed laser deposition on sapphire substrates were systematically characterized utilizing the Hall effect x-ray photoelectron spectroscopy (XPS) measurements. Oxygen growth pressure postannealing processing play a great role in these films. Increasing oxygen from 5 to 20 Pa enhanced resistivity three orders magnitude. at 700 °C under O2 exhibited p-type conductivity with hole concentration 5×1017 cm−3 mobility 0.3...
C4H nanotube (C4HNT) which is a novel kind of hydrogenated carbon nanotubes (CNTs) has gradually attracted much attention due to its unique structure and potential applications. In this work, we systematically studied the mechanical properties C4HNT using classical molecular dynamics mechanics simulations. It found that can bear greater radial pressure than CNT. For example, collapse (10, 0) reach 25 GPa, more 4 times CNT (6 GPa). However, hydrogenation weakens value Young's modulus CNT,...
We use ray optics to calculate the radiation forces on a dielectric microsphere in evanescent field of an optical nanofiber. theoretically demonstrate that gradient force may attract onto fiber surface. The scattering transport along and light propagating direction. impact sphere-fiber distance, sphere radius, radius are investigated. nanofiber can be optimized for particle transportation.
We study the buildup of spatial correlation in a two-dimensional dissipative Rydberg system using time-dependent variational principle. find that sweeping process Rabi frequency and detuning, moderately large decay rate induced by two-photon excitation scheme suppresses significantly long-time scale agreement with experimental results. A relatively dephasing leads to short relaxation time for antiferromagnetic reach stable value. These results provide general view about role various...
Lake ecosystems are impacted by anthropogenic disturbances and have become vulnerable worldwide. Highly disturbed lake not well understood due to the lack of data on changes in structures functions ecosystems. In this paper, we focus Baiyangdian (BYDL), largest shallow North China. Following establishment Xiong’an New Area (XNA) 2017, concerted efforts restore BYDL’s aquatic environment been undertaken, which has led significant We evaluated biomass dynamics main biological communities...
An optical fiber laser with a stable wavelength and narrow linewidth spectrum is investigated by locking its to the peak transmitting of Fabry–Perot filter. A Bragg grating reflects fluorescence emitted from erbium-doped as gain light; thus, can be selected freely fiber. The locked filter, which compensates for influences resulting ambient disturbances feedback loop. stability exceed 10 −8 .
An improved tube etching method to fabricate high-quality fiber probes for optical tweezers by reserving a certain length of bare form T-type composite structure was proposed and implemented. This can overcome the impact types on quality in conventional effectively. Based influence gravity diffusion motion reactants, analysis formation mechanism this method. procedure retained advantage smooth surface traditional but shortened time. Our results also demonstrated that light transmittance...
We theoretically and experimentally study the optical trapping of two different microparticles by a double-tapered fiber probe (DOFP) which is fabricated interfacial etching method. A SiO2 microsphere yeast, or microspheres with diameters, are trapped. calculate measure forces on microparticles, discuss impacts geometrical size refractive index forces. Both theoretical calculation experimental measurements indicate that if particles have same index, larger second particle is, force is....

The is first etched means of meniscus-based to obtain one-tapered tip, which again between etchant and overlay a tip. formation mechanism second taper analysed. impacts time, HF concentration on cone angle are discussed. can be controlled time overlay. But has few angle. applied for contactless trapping particles.
We theoretically propose that electromagnetically induced transparency (EIT) with cold Rydberg atoms in the proximity to a metallic chip surface can be applied detect and investigate Casimir–Polder effect. The absorption spectrum of probe laser is numerically computed by Monte Carlo method, taking into account atom-surface interactions (Casimir–Polder effect). results show effect shifts energy level state leads shift EIT window. resonant frequency depends on principal quantum number,...
