Two facile and efficient methods, to synthesize zinc oxide (ZnO) particles with different morphologies, have been reported here. Thermal decomposition route yielded micron sized irregular shaped ZnO particles. While co‐precipitation method rendered transparent flakes which then transformed to hexagonal discs with rela…
Aiming at mimicking water strider's water-surface locomotion, this study proposes a new miniature surface tension-driven robot. A key feature of this robot is that its actuating legs possess ellipse-like spatial trajectories like water strider by using a cam-link mechanism, and never pierces water surface when rowing.…
Large steel ingots with homogeneous internal quality are critical to the key components of the heavy equipments. Multi-pouring (MP) process, i.e. the sequential pouring with different carbon concentration, is widely applied for the production of steel ingots. Multi-pouring process aims to build an initial delaminated…
Rare earth Eu3+ion doped barium zirconate titanate (Ba1-xEu2x/3Zr0.3Ti0.7)O3(x = 0.00 - 0.10) ceramics were prepared by using the solid state reaction route and the effect of doping concentration on structural and dielectric relaxation behavior of the ceramics were studied. The structural and microstructural analyses…
In this work, the elastic properties and relative stability of graphene-like Tan+1Cn monolayers have been studied by first-principles calculation. The lattice constants, thickness of monolayer, density of states, and charge transfer of Tan+1Cn monolayers were calculated and compared with the [Tan+1Cn] block in the par…
The results of an investigation into the imaging of rectangular grooves in silicon, which are obtained using a scanning electron microscope operating in the backscattered electron recording mode, are presented. Three imaging mechanisms are revealed, and their contributions are separated experimentally. One of the mech…
There is a higher incidence of brain tumours in the UK than the world average for both men (8.1 per 100,000), and women (5.3 per 100,000). Malignant gliomas are the most common primary brain tumours of which glioblastoma (GBM) is the most prevalent. GBM is also known to be the most biologically aggressive and cellular…
Silicon-oxide thin films were deposited on polyethylene-terephthalate (PET) and glass substrates for applications in transparent barrier packaging and replacement display cover glasses by using plasma-enhanced chemical vapor deposition (PECVD). The bias conditions and the input power in the radio-frequency plasma were…
The present work is devoted to the fabrication of silver nanoparticles by the electrochemical method. Metal silver plates served as the cathode and anode. The dependence of silver nanoparticles sizes on the experimental parameters has been investigated. The average size of metal silver nanoparticles (∼ 10 nm) was dete…
Ferrites with hexagonal crystal symmetry have received much scientific and technological attention in their centimeter-/or even millimeter- (mm-) wave applications, since the hexagonal crystal symmetry leading to high magnetocrystalline anisotropy energies and subsequently high ferromagnetic resonance frequencies, amo…
The main focus in this research was to understand the influence of Dy 3+ and Eu 3+ doping/co-doping and sintering atmosphere on the luminescence properties of SrB 2 Si 2 O 8 . Single phase Eu and Dy doped/co-doped SrB 2 Si 2 O 8 ceramics were synthesized in different atmosphere through solid state reaction technique.…
The influence of alloying elements on the stacking fault energy (SFE) of magnesium alloys containing long period stacking ordered (LPSO) structure was studied systematically by means of first-principles calculation. The element features and criterion of formation of LPSO in Mg–RE–X system was discussed, when X = Zn, C…
Abstract Azo dyes have played an important role in the development of the chemical industry for 150 years. The azo‐core of these dyes can undergo trans to cis photoisomerization, which allows azobenzene derivatives to act as light triggered molecular switches. Here, we showed that simple derivatization of Sudan I prov…
In article number 1500091 Hao Ming Chen, Bin Liu, and co-workers report a new hierarchical Ni-Co oxide nanostructure composed of small secondary nanosheets grown on primary nanosheet arrays, which is synthesized to decrease the overpotential and facilitate the catalytic reaction. The Ni ions located in the tetrahedral…
The influence of preliminary rolling on the mechanical behavior of amorphous polyethylene terephthalate (PET) has been studied. Samples were oriented via rolling at room temperature on laboratoryscale rolls. After low rolling degrees (λ = 1.15), the tensile yield point decreases; i.e., the effect of strain softening i…
The results of the thermal modification of AG-OV-1 and SKD-515 activated carbons under varied conditions (by atmospheric oxygen and in an atmosphere of nitrogen) are reported. It was determined that, on the thermal oxidation under selected conditions, the formation of surface oxygen compounds predominated over the pro…
Control of the solids content after vacuum dewatering is vital for efficient control and energy use of the paper machine. Dewatering is a complex function of many parameters such as fibre and pulp properties as well as settings on the paper machine and a predictive model for dewatering will require extensive and detai…
Quantum algorithms often assume independent spin qubits to produce trivial , mappings. This can be unrealistic in many solid-state implementations with sizeable magnetic interactions. Here we show that the lower part of the spectrum of a molecule containing three exchange-coupled metal ions with and is equivalent to n…
Fluoroethylenepropylene (FEP) piezoelectret films with a cross-tunnel structure were prepared using a template-based process and contact charging. Energy harvesting from the fabricated FEP films was investigated in the {3-3} mode at various seismic masses, load resistances and exciting frequencies. The results show th…
This paper mainly investigates the creep property of polyurethane composites. The polyurethane composites with different structures are first prepared and experiments are subsequently carried out to study their creep property in terms of molecular weight of soft segments, isocyanate structure and cross-linking degree.…
