Abstract Pressure sensitive robotic skins have long been investigated for applications to physical human-robot interaction (pHRI). Numerous challenges related to fabrication, sensitivity, density, and reliability remain to be addressed under various environmental and use conditions. In our previous studies, we designe…
It is known that the slot frequency vibration is the one of the main components in electromagnetic vibration spectrum of permanent magnet DC motors (PMDCM). After finding that the vibration reduction scheme of the piecewise varying pole width (PVPW) is only effective for the odd order harmonic of slot frequency vibrat…
Abstract In surface waters, the illumination of photoactive engineered nanomaterials (ENMs) with ultraviolet (UV) light triggers the formation of reactive intermediates, consequently altering the ecotoxicological potential of co-occurring organic micropollutants including pesticides due to catalytic degradation. Simul…
Abstract Organic solar cells are considered to be the promising solar technology for the coming year because of their ease of manufacture. In the present study, the Aloe Latex as a yellow orange Solid (ALS) collected from the leaves of Aloe Vera plant (aloe barbadensis miller) was used as a natural and cheap sensitize…
Many mini-implantable devices have been developed and fabricated for diagnostic and treatment purposes. Wireless implantable biomicrosystems provide a desirable approach for long-term physiological signal monitoring. In this study, we implemented a wireless implantable biomicrosystem for bladder-cavity pressure measur…
Raman and coherent phonon spectroscopies were used to investigate the thickness-dependent phononic properties of ultrathin single-crystal Bi films prepared by molecular beam epitaxy on Si(111) substrates. Both the A1g and Eg Raman peaks disappeared in the Raman spectra of a 4 nm Bi film, indicating a complete transiti…
Hydrogel forming physical networks based on gelatin are an attractive approach toward multifunctional biomaterials with the option of reshaping, self-healing, and stimuli-sensitivity. However, it is challenging to design such gelatin-based hydrogels to be stable at body temperature. Here, gelatin functionalized with d…
Single-crystal perovskite with no grain boundaries improves the performance of perovskite solar cell compared with its polycrystalline counterpart. Owing to its stability and excellent defect physics, it has enormous potential in the field of photovoltaics. In this article, a comprehensive numerical evaluation of sing…
Three complexes of the general formula M{CpFe(η5‐C5H4CH=N–N=C(S)NH2}2 [where M = NiII (2a), PdII (2b) and ZnII (2c)] were synthesized with formylferrocene thiosemicarbazone (1) as a bidentate ligand. All compounds were characterized using conventional spectroscopic and analytical techniques (infrared, 1H and 13C NMR,…
Ascorbate (AsA) is required as a cofactor and is widely distributed in plants and animals. Recently, it has been suggested that the nematode Caenorhabditis elegans also synthesizes AsA. However, its biosynthetic pathway is still unknown. To further understand AsA biosynthesis in C. elegans, we analyzed the incorporati…
Summary The coupling effects of humidity‐heat on the thermal protective performance of protective clothing play an important role during the fire fighting process. The thermal stability, heat release, and thermal protective performance of protective clothing were investigated under the coupling effects of humidity‐hea…
Abstract The binding of thiols on hexadecyltrimethylammonium bromide (CTAB)-capped gold nanorods is investigated both at the ensemble and individual particle level using two similar sized but oppositely charged small molecules, namely, cysteamine and mercaptopropionic acid (MPA). Changes in the width and position of t…
Advanced techniques for analysis of XRD patterns and optical absorption spectra were employed to derive in-depth physical insights into the structure and properties of quantum nanocrystals of the cubic modification of CuInS 2 synthesized by a sonochemical route. Three-dimensional assemblies of the synthesized nanocrys…
Understanding the properties of defects is crucial to design higher performance semiconductor materials because they influence the electronic and optical properties significantly. Using ab initio calculations, the dynamics properties of nitrogen interstitial in GaN material, including the configuration, migration, and…
Abstract The kinetics of Sn whisker growth was investigated on vacuum-evaporated Sn thin-films. Sn film layers were deposited on a Cu substrate with 0.5 and 1 µm thicknesses. The samples were stored in room conditions (22 ± 1 °C/50 ± 5RH%) for 60 days. The Sn whiskers and the Cu–Sn layer structure underneath them were…
As known, the modulus method is one of the most powerful research tools in the theory of mappings. Distortion of modulus has an important role in the study of conformal and quasiconformal mappings, mappings with bounded and finite distortion, mappings with finite length distortion, etc. In particular, an important fac…
This Letter studies the dielectric responses of nanocomposites of poly(ether methyl ether urea) (PEMEU) with alumina nanofillers at less than 0.7% volume loading (0.7 vol. %). The results show that the dielectric constant K of PEMEU nanocomposites is enhanced by the nanofillers. The enhancement peaks at 0.33 vol. % na…
One of the nanowire (NW) characteristics is its preferred elongation direction. Here, we investigated the impact of Si substrate crystal orientation on the growth direction of GaAs NWs. We first studied the self-catalyzed GaAs NW growth on Si (111) and Si (001) substrates. SEM observations show GaAs NWs on Si (001) ar…
BiOCl nanosheets nucleated and grew on cottage cheese-like SiC substrate via hydrothermal procedure, through which a tight heterojunction was formed. SiC/BiOCl composites with varied morphologies were acquired that the formation of BiOCl was involved with different form of carbon existed on surface of SiC. The photoca…
Multinucleon transfer mechanism in the collision of $^{238}\mathrm{U}+^{238}\mathrm{U}$ system is investigated at ${E}_{\text{c.m.}}=833$ MeV in the framework of the quantal diffusion description based on the stochastic mean-field approach. Double cross sections $\ensuremath{\sigma}(N,Z)$ as a function of the neutron…
