This paper focuses on motion control of a piezo-based dual-stage nanopositioner where hysteresis and dynamic effects dominate the output response. A typical dual-stage micro/nano-scale positioning system consists of a long-range, low-speed actuator connected in series with a short-range, high-speed actuator. This arra…
We report our ultrafast photoinduced desorption investigation of the coverage dependence of substrate-adsorbate energy transfer in carbon monoxide adlayers on the (111) surface of palladium. As the CO coverage is increased, the adsorption site population shifts from all threefold hollows (up to 0.33 ML), to bridge and…
The time and position behavior of runaway electrons at the Parail–Pogutse instability moments has been investigated using experimental observations in plasma current, loop voltage, the Hard X-ray (HXR) radiations, and 18 poloidal pickup coils signals received by data acquisition system simultaneously. The conditional…
During scale-up of microbial fuel cell (MFC), a proportional increment in power does not usually occur determining the importance of maximum possible anode chamber volume (Van) to exploit electrogenesis and achieve maximum energy recovery. A systematic approach is proposed for determining the optimal single anode cham…
In this study, bioactive scaffold of nano magnesium phosphate (nMP)/wheat protein (WP) composite (MWC) was fabricated. The results revealed that the MWC scaffolds had interconnected not only macropores (sized 400-600 μm) but also micropores (sized 10-20 μm) on the walls of macropores. The MWC scaffolds containing 40 w…
Abstract The development of inexpensive and effective catalysts for oxygen reduction reaction (ORR) has become one of the most important topics. Herein, we designed a novel MnCo 2 O 4 /N,S‐doped carbon nanotubes hybrid nanocomposite, which was synthesized via facile solvothermal and solution‐based oxidation‐precipitat…
Drug-eluting stents are an effective therapy for symptomatic arterial obstructions, substantially reducing the incidence of restenosis by suppressing the migration and proliferation of vascular smooth muscle cells into the intima. However, current drug-eluting stents also inhibit the growth of endothelial cells, which…
This paper aims to provide a coupled finite element method (FEM) and smoothed particle hydrodynamics (SPH) approach capable of reproducing the blast response in rock. In the proposed approach, SPH is used to simulate large deformation and fracture of rock at the near detonation zone, while the FEM is adopted to captur…
The Pickett effect is the phenomenon of creep enhancement during transient drying. It has been observed for many nanoporous solids, including concrete, wood and Kevlar. While the existing micromechanical models can partially explain this effect, they have yet to consider nanoscale dynamic effects of water in nanopores…
Hall measurement using the van der Pauw technique is a common characterization approach that does not require patterning of contacts. Measurements of the Hall voltage and electrical resistivity lead to the product of carrier mobility and carrier concentration (Hall coefficient) which can be decoupled through transport…
Chains in a polymer network deform nonaffinely at small length scales due to the ability for extensive microscopic rearrangement. Classically, the conformations of an individual chain can be described solely by an end-to-end length. This picture neglects interchain interactions and therefore does not represent the beh…
Abstract Electrochemical magnetoimmunosensors combine a number of issues that guarantee extremely high performance and also compatibility with the study of complex sample matrices. First, analyte immunocapture exploits the high affinity and specificity of antibodies. Second, magnetic particles (MP) provide faster and…
Several reports have been published on the isolation, culture, and identification of mesenchymal stem cells (MSCs) from different anatomical regions of the umbilical cord (UC). UC is suitable for standardizing methods of MSC isolation because it is a uniform source with high MSC numbers. Although the UC is considered…
Non-intrusive monitoring of health state of induction machines within industrial process and harsh environments poses a technical challenge. In the field, winding failures are a major fault accounting for over 45% of total machine failures. In the literature, many condition monitoring techniques based on different fai…
Nonlinear composites consisting of insulation matrix and functional fillers are potential materials for field grading and stress control due to their field-dependent electrical parameters. One main task for the application of nonlinear composites is to tailor their nonlinear property to meet the specific field grading…
The purpose of this study was to compare two minimally invasive surgical techniques (MISTs) for the treatment of periodontal defects: (1) guided tissue regeneration (GTR) using resorbable minimembrane and particulate xenograft (DBBM); and (2) inductive periodontal regeneration (IPR) using enamel matrix derivatives and…
In this paper the influence of silicon content of 3,1 to 5,4 wt.% on the tensile properties, hardness and impact energy of ferritic ductile iron was analysed.It was found that silicon strengthens the ferrite, resulting in an increase in yield strength and tensile strength with increasing silicon content up to 4,22 wt.…
For neutral hard-sphere solutes, we compare the reduced density profile of water around a solute g(r), solvation free energy μ, energy U, and entropy S under the isochoric condition predicted by the two theories: dielectrically consistent reference interaction site model (DRISM) and angle-dependent integral equation (…
The main cause for failure of composite laminates is delamination under shear or transverse loading. A common approach to prevent such failure is to introduce a discrete interleaf at the midplane of the laminate in order to increase its fracture toughness and, consequently, its resistance to delamination. Accordingly,…
We report "smart" nickel oxide nanoparticles (NOPs) as multimodal cancer therapy agent. Water-dispersible and light-sensitive NiO core was synthesized with folic acid (FA) connected bovine serum albumin (BSA) shell on entrapped doxorubicin (DOX). The entrapped drug from NOP-DOX@BSA-FA was released in a sustained way (…
