Biological samples are radiation-sensitive and require imaging under low-dose conditions to minimize damage. As a result, images contain a high level of noise and exhibit signal-to-noise ratios that are typically significantly smaller than 1. Averaging techniques, either implicit or explicit, are used to overcome the…
In this paper, the magnetic losses of a supply current sensor dedicated to circuit breakers are investigated. Measurements were performed using an accurate calorimeter covering a measurement range of [1 mW; 10 W]. Several frequencies and voltages were tested. A model of the sensor’s core material (NO SiFe sheet M250-5…
A tree T(V, E) is graceful if there exists an injective function f from the vertex set V(T) into the set {0, 1, 2, ..., ∣V∣ − 1} which induces a bijective function fʹ from the edge set E(T) onto the set {1, 2, ..., ∣E∣}, with fʹ(uv) = ∣f(u) − f(v)∣ for every edge {u, v} ∈ E. Motivated by the conjecture of Alexander Ro…
We have successfully fabricated well-defined Au-core and polydiacetylene-shell hybridized nanoparticles (NPs) having the suitable thickness of dielectric SiO2 layer between Au-core and polydiacetylene-shell by coprecipitation/microwave irradiation method, and subsequent solid-state polymerization process. The resultin…
The dominant oxidation state of cadmium is +ii. Although extensive investigations into the +ii oxidation state have been carried out, the chemistry of CdI is still largely underdeveloped. Here, we report a new functionality of cadmium created by the zeolite lattice: room temperature O transfer from N2O to CO mediated…
A miniature-scale device for harvesting of vibrational energy is presented, which is based on the inverse magnetic shape memory effect caused by stress-induced reorientation of magnetic moments. The active material is a bulk NiMnGa sample of 1 mm × 2.5 mm × 4.5 mm. A new harvester design is developed consisting of a m…
In this paper, plasma disruption was investigated in IR-T1 tokamak. Moreover, the time evaluation of plasma parameters such as plasma current, I p ; loop voltage, V loop ; power heating; and safety factor was illustrated. The results of diamagnetic loop and Mirnov oscillations in a major disruption were compared with…
Usually, the color of a spark formed by an incandescent particle is controlled by its temperature according to gray body radiation. With the help of low boiling metals, gas phase combustion and consequently element‐specific emission can be achieved. Here, we report on a detailed discussion of colored sparks in the con…
In the different processes of investment casting, the stress states of the ceramic shell mold are different. The widely used bending strength at present is not a reasonable characteristic parameter for the overall measurement of mechanical properties of ceramic shell mold. In this paper, two special kinds of strength…
A escassez de informaes sobre as caractersticas das madeiras de mogno africano e de sua trabalhabilidade limitam sua utilizao e introduo no mercado madeireiro. Os objetivos foram avaliar a qualidade da superfcie usinada e comparar o consumo de energia especfica de corte entre as espcies das madeiras de Khaya ivorensis…
This study deals with the Rotary Friction Welding, (RFW) as a variation of friction welding in which the energy required to make the weld is supplied primarily by the stored rotational kinetic energy of the welding machine. The mechanical energy generated in overcoming friction is continuously transformed into heat. I…
Ultrathin two-dimensional 2PbCO 3 ·Pb(OH) 2 nanosheets have been facilely synthesized at the gas/liquid interface and exhibit higher catalytic activity as peroxidase mimetic for the oxidation of TMB.
Hydrogen peroxide (H 2 O 2 ) is one type of reactive oxygen species (ROS) that can lead to a variety of forms of oxidative stress damage in human beings. Numerous methods have been used to detect H 2 O 2 concentrations in various environments, however, these often suffer from inadequate detection limits, instrumental…
We built a full-dimensional analytical potential energy surface of the ground electronic state of Li2H from ca. 20,000 ab initio multi-reference configuration interaction calculations, including core–valence correlation effects. The surface is flexible enough to accurately describe the three dissociation channels: Li…
Abstract The light emitting polymers (LEPs) were synthesized by aromatic nucleophilic substitution reaction containing o ‐terphenyl substituted fluorene (TERF) and diphenylanthracene (DPA) units. The obtained polymers showed emission in the blue region. The polymers were successfully characterized by elemental analysi…
Aim of study: This study aimed to determine the effects of glass fiber reinforced polymer (GFRP) and adhesives type on the diagonal compression and tensile strength in L-type corner joints connected by a wood biscuit. Material and Methods: Medium density fiberboard coated with melamine plate (MDFlam), wood biscuit wit…
Abstract The front cover artwork for issue 24/2018 is provided by scientists at the Universität Leipzig, Max Planck Institute of Colloids and Interfaces, and Institute for Non‐Classical Chemistry e. V. (Germany). The image illustrates the use of IR microimaging for monitoring the mean concentration of both reactant an…
The study of the standard formation enthalpy, entropy, and heat capacity for key species relevant to the low-temperature combustion of cyclohexane has been performed by applying the group additivity method of Benson. The properties of 18 Benson groups (8 of them for the first time), and 10 ring correction factors for…
Aromatic donor–acceptor stacking involving electron-rich π-donors and electron-deficient π-acceptors has been utilized in a broad spectrum of diverse applications to great effect.
Metallosilicates (metal = Al, Ti, Zr, V and Ce) and silica supports were synthesized by a one-pot surfactant-free process for use in cobalt-based Fischer–Tropsch catalysts. The in-depth physical, chemical, and textural properties of all supports were determined by several characterization techniques. The introduction…
