A super-low friction coefficient of 0.0028 is measured under a pressure of 300 MPa when the friction pair (the silicon nitride ball sliding on the silicate glass) is lubricated by the mixed aqueous solution of glycerol and boric acid. The morphorlogies of the hydroxylated glass plate are observed by an atomic force mi…
This paper reviews different methodologies for the fabrication of various ceramic one-dimensional (1D) nanostructures (nanotubes/fibres/wires/belts, etc.) produced by using preceramic polymers. Diverse processing approaches together with a wide range of precursor types enable the fabrication of 1D nanostructures with…
When a gas is injected into a bubble in an elastomer, the bubble may first expand gradually, and then snap suddenly to a large size. This snap-through instability is analyzed here using a model that accounts for both the surface tension and the limiting stretch of the elastomer. In a state of equilibrium, the pressure…
For the description of a permanent magnet excited synchronous machine the idealized equations of common synchronous machines can be used omitting the damping windings and replacing the current excitation by a permanent flux. For a more accurate modeling, nonideal behavior like saturation, cross-coupling magnetization…

Cobalt nanoparticles on a porous support, typically alumina, are widely used in Fischer–Tropsch (FT) processes to convert natural gas into synthetic fuel. To optimize the efficiency of these catalysts and the FT process, a fundamental understanding of the catalyst structure and behaviour must be obtained on the nanome…
Many-core chip design has become a popular means to sustain the exponential growth of chip-level computing performance. The main advantage lies in the exploitation of parallelism, distributively and massively. Consequently, the on-chip communication fabric becomes the performance determinant. In the meantime, the intr…
Abstract This review describes monovalent synthetic receptor–ligand (or host–guest) pairs with extremely high binding affinity, comparable to that of the biotin–avidin pair, and their applications. Cucurbit[7]uril (CB[7]), a member of the host family cucurbit[n]uril (CB[n], n=5–8, 10), forms ultrastable host–guest com…
Improving the efficacy of drug delivery via nanocarriers has been a major issue in the field of intravenous delivery. In this study, a polymeric nanogel was developed to enhance the stability, redox responsiveness, and the efficacy for intracellular protein delivery. The thiolated heparin-Pluronic conjugate was self-a…
Droplets on hydrophobic surfaces are ubiquitous in microfluidic applications and there exists a number of commonly used multicomponent and multiphase lattice Boltzmann schemes to study such systems. In this paper we focus on a popular implementation of a multicomponent model as introduced by Shan and Chen. Here, inter…
Abstract This account highlights three significant fields of applications for cucurbiturils (CBs). The first relates to cucurbituril‐based devices and sensors involving spectral effects associated with the formation and dissociation of inclusion complexes. The second refers to the use of CBs as catalysts that control…
A method for designing frequencies and modes in ultrasonic transducers above the very-high-frequency (VHF) range is required for ultrasonic non-destructive evaluation and acoustic mass sensors. To obtain the desired longitudinal and shear wave conversion loss characteristics in the transducer, we propose the use of a…
Electromigration (EM) is a critical problem for interconnect reliability of modern IC design, especially as the feature size becomes smaller. In 3D IC technology, the EM problem becomes more severe due to drastic dimension mismatches between metal wires, through-silicon-vias (TSVs), and landing pads. Meanwhile, the th…
In this article, we have reported the fabrication of stable macroporous ceramic support using low-cost inorganic raw materials by uniaxial dry compaction technique. The supports were prepared by mixing of inexpensive raw materials such as kaolin, quartz, calcium carbonate, sodium carbonate, boric acid, sodium metasili…
This present study has been conducted to assess the viability of mixing increasing amounts of coffee ground as a solid waste material (1–5 wt-%) with raw clay. Samples have been compressed, dried and fired at 950°C for 24 h to laboratory scale. Using coffee grounds as organic residue has been proven to be effective fo…
Experiments were performed to size, count, and obtain shell parameters for individual ultrasound contrast microbubbles using a modified flow cytometer. Light scattering was modeled using Mie theory, and applied to calibration beads to calibrate the system. The size distribution and population were measured directly fr…
[1] Measurements of gaseous nitrogen and sulfur oxide emissions in young aircraft exhaust plumes give insight into chemical oxidation processes inside aircraft engines. Particularly, the OH-induced formation of nitrous acid (HONO) from nitrogen oxide (NO) and sulfuric acid (H2SO4) from sulfur dioxide (SO2) inside the…
We report the demonstration of a N-polar InGaN based green light emitting diode (LED) grown by N2 plasma-assisted molecular beam epitaxy (PAMBE). High quality multiple quantum well LEDs with In0.29Ga0.71N quantum wells were grown at a temperature of 600 °C by applying a new growth model. LED structures exhibited green…
The misfolding and aggregation of amyloidogenic polypeptides are characteristics of many neurodegenerative syndromes including Alzheimers and Parkinsons disease. There is a major interest in the availability of amyloid-specific probes that exhibit fluorescence properties for its use as reporters of protein aggregation…
It is assumed in the theories of Earth formation that the composition of gases extracted by primary planetary magmas is formed by the large-scale melting of the early mantle, which occurred in the presence of a metallic Fe phase. The molten Fe metal and silicate materials underwent gravitational migration, which affec…
