Biomimetic actuation technologies with high muscle strokes, cycle rates, and work capacities are necessary for robotic systems. We present a type that operates based on changes in stiffness caused by volume expansion. This is created coiling mechanically strong braid, which an elastomer hollow tube adhesively attached inside. show the reversibly contracts 47.3% when driven oscillating input air pressure of 120 kilopascals at 10 Hz. It generates maximum power density 3.0 W/g demonstrates...

The process of laser fire polishing optical glasses is shown to work very well for materials with small coefficients thermal expansion. surfaces other crack during or cool down from an elevated preheat temperature. An analytical model described and used show that, in which cannot be fire-polished, the thermal-gradient stress resulting differential expansion exceeds yield stress. Successful fused quartz Pyrex reported.
The impact behaviors of droplets on nanostructure-arrayed surfaces are ubiquitous in nature and engineering applications. And the influence position a droplet its bouncing dynamics is great significance since there inevitable randomness surface nanostructured arrays, but difference process caused by this has not been recognized. Here, using molecular simulations, effect water nanopillar-arrayed systematically investigated. simulation results highlight that plays an important role after...
Abstract Designing and manufacturing multi-component alloy samples with ultralow magnetic susceptibility χ (<10 −6 cm 3 mol −1 ) is crucial for producing high-quality test masses to successfully detect gravitational wave in the LISA TianQin projects. Previous research has idenfified AuPt alloys as a potential candidate masses, capable of achieving that meets requirements from both theoretical experimental perspectives. In this study, we discover structural strain regulation (i.e. tensile...
Self-propelled jumping of droplets on solid surfaces is essential for many natural and engineering processes. Specifically, rational design based micro-/nanostructures enables a merged droplet to jump spontaneously after the coalescence two droplets. However, self-jumping highly challenging nanodroplets due significant energy dissipation. Herein, we show enhancement nanodroplets' self-propelled with properly designed nanocone arrays hydrophobic using molecular dynamics simulation. The...
In this article, we use optical transmission spectroscopy to measure the changes in resonance features of a Au plasmonic nanoresonator array consisting concentric ring/disc cavity elements, when graphene is introduced as an encapsulating medium. We show that by using finite element modelling best reproduce our experimental results dielectric response film can be determined. discuss potential such structures for chemical sensing applications.
Inelastic neutron scattering experiments were performed to investigate the crystalline electric field (CEF) excitations of ${\mathrm{Nd}}^{3+}$ (J = 9/2) in iron pnictide NdFeAsO. The crystal level structures for both high-temperature paramagnetic phase and low-temperature antiferromagnetic NdFeAsO are constructed. variation CEF reflects not only change local symmetry but also magnetic ordered state Fe sublattice. By analyzing interaction with a Hamiltonian, parameters obtained. It was found...
In a multivalent salt solution, segment of DNA is modeled as an elastic rod subjected to the interfacial traction. The shooting method used calculate equilibrium configurations condensed under action longitudinal end-force and traction simultaneously. results show that shapes are mainly determined by competition between energy strain stretching. change end-to-end distance with consistent worm-like chain (WLC) model. higher concentration is, stronger condensation DNA.
Abstract An ab initio core-shell model is proposed to evaluate the surface effect in bending nanowires, which elastic modulus depends on relaxation and deformation induced by external loading. By using first-principles calculations based density functional theory (DFT), bulk properties are calculated for Ag, Pb, Si nanowires. The obtained theoretical predictions of effective Young’s nanowires agree well with experimental data, shows that fixed-fixed nanowire stiffened cantilevered softened...
We have used polarized and unpolarized neutron diffraction to determine the spatial distribution of magnetization density induced by a magnetic field 9 T in tetragonal phase K0.8Fe1.6Se2. The maximum entropy reconstruction shows clearly that most is confined region around iron atoms whereas there no significant associated with either Se or K atoms.
