Abstract Reaction of p‐phenylenediacetonitrile (p‐phda) with AgCF3COO afforded the coordination polymer, {[Ag2(p‐phda)2] [Ag4(CF3COO)6]}n (1), where the 1D cationic [Ag2(p‐phda)2]2+ chain acts as host and the anionic [Ag4(CF3COO)6]2– as guest molecules occupy the channel between neighboring host chains. This is a rare…
This work focused on the design, development and construction of a new low cost soldering iron that works by means of induction heating. The amount of electronic components has been minimized in order to reduce production costs. Additional tests were undertaken to determine the ideal tips for soldering, and the adapta…
The aim of this work was to monitor in-line and at a real time, the solid-state forms during pharmaceuticals manufacturing. It concerns the dehydration behavior and the solid-state transitions of theophylline in an agitated vacuum contact dryer. First, a near infrared spectroscopy (NIRS) method was performed using a r…
Nowadays printing can be defined as the reproduction of patterns by transfer of matter to a surface by mechanical force or hydrodynamic stress. For this, functional materials need to be transformed to a physical condition in which they can be mechanically transported, subdivided, deformed, and deposited: the liquid st…
Disturbance characteristics of cross-point resistive random access memory (RRAM) arrays are comprehensively studied in this paper. An analytical model is developed to quantify the number of pulses (#Pulse) the cell can bear before disturbance occurs under various sub-switching voltage stresses based on physical unders…
Abstract In this work, a different kind of parity-time ( PT ) symmetric one-way cloak is proposed. Different from conventional PT -cloak, it enjoys the property of isotropic modulation for refractive index profiles. By combining PT -symmetry with the concept of cloaking at a distance, the dilemma of realizing anisotro…
The objective of the paper is a comparison of different hardness measuring methods for the evaluation of mechanical properties in a wide load range (7-250 mN) for heterogeneous structures. Vickers nano and microindentation hardness test was used for mechanical properties assay of chosen samples. Relationships between…
In this article, modified activated carbon fiber (ACF) adsorbing emulsified oil is proposed as an effective method to treat oil spill. At first, the ACF was modified by HNO3, and the adsorption was studied in batch mode. Then, single factor experiment and the response surface methodology were applied to optimize the a…
This work evaluates the nanohardness of a single alumina grain for a coarse grain alumina ceramic of ∼10 μ m grain size. The results reveal that the nanoscale contact deformation resistance of the single grain has a unique self-adjusting characteristic. It increases in response to enhancement in the externally applied…
Significant advancements in biodegradable polymeric materials have been made for numerous biomedical applications including tissue engineering, regenerative medicine, and drug delivery. The functions of these polymers within each application often rely on controllable polymer degradation and erosion, yet the process h…
Abstract: We outline the details of acquiring quantitative 13C cross‐polarization magic angle spinning (CPMAS) nuclear magnetic resonance on the most ubiquitous polymer for organic electronic applications, poly(3‐hexylthiophene) (P3HT), despite other groups' claims that CPMAS of P3HT is strictly nonquantitative. We la…
This paper presents the effect of kenaf fibre and steel fibre mixed and added into reinforced concrete beams. In investigating the structural behaviour of the beams, four-point bending tests were conducted on six beams by considering two distinct parameters; (i) shear reinforcement arrangement (ii) volume of fraction…
Optimization of micropipette fabrication by laser micromachining for application in an ultrafine atmospheric pressure plasma jet using response surface methodology, Wang, Tao, Liu, Jingquan, Yang, Bin, Chen, Xiang, Wang, Xiaolin, Yang, Chunsheng
Three-dimensional integration is considered to be a promising technology to tackle the global interconnect scaling problem for terascale integrated circuits (ICs). Three-dimensional ICs typically employ through-silicon-vias (TSVs) to vertically connect planar circuits. Due to its immature fabrication process, several…
Abstract In future nuclear fusion reactors high heat load events, such as edge-localised modes (ELMs), can potentially damage divertor materials and release impurities into the main plasma, limiting plasma performance. The most difficult to handle are type I ELMs since they carry the largest fraction of energy from th…
One of the primary challenges in single particle reconstruction with cryo-electron microscopy is to find a three-dimensional model of a molecule using its noisy two-dimensional projection-images. As the imaging orientations of the projection-images are unknown, we suggest a common-lines-based method to simultaneously…
Particle size-dependent superspin glass behavior in random compacts of monodisperse maghemite nanoparticles, Andersson, Mikael Svante, Mathieu, Roland, Normile, Peter S, Lee, Su Seong, Singh, Gurvinder, Nordblad, Per, Toro, Jose Angel De
We study the relative translation of two arbitrarily shaped objects, caused by their hydrodynamic interaction as they are forced through a viscous fluid in the limit of zero Reynolds number. It is well known that in the case of two rigid spheres in an unbounded fluid, the hydrodynamic interaction does not produce rela…
The research efforts for silicone based elastomers with high dielectric permittivity (Ɛ’) intensified significantly in the last years since such materials would allow the construction of dielectric elastomer actuators (DEA) with low operation voltages. Polar groups can be introduced to elastomers to adjust their permi…
Two new congruent‐melting alkali metal diphosphates, Rb2CdP2O7 and Cs2CdP2O7, were synthesized by conventional solid‐state reactions. Single‐crystal X‐ray structural analyses showed that M2CdP2O7 (M = Rb, Cs) feature two‐dimensional [CdP2O7]2– layers that are composed of CdO5 pyramids and P2O7 dimers. The Rb+ and Cs+…
