Abstract This article presents the fabrication of electrohydrodynamically printed energy harvesters based on piezoelectric polyvinylidene fluoride (PVDF) nanofibers. PVDF nanofibers with β phase formation are fabricated by mechano‐electrospinning to realize in situ electric poling and mechanical stretching. By directl…
Magnetic nanoparticles (MNPs) are used as therapeutic and diagnostic tools, such as for treating hyperthermia and in magnetic particle imaging, respectively. Magnetic relaxation is one of the heating mechanisms of MNPs. Brownian and Néel relaxation times are calculated conventional theories; however, the influence of…
Microbially-induced concrete corrosion in headspaces threatens wastewater infrastructure worldwide. Models for predicting corrosion rates in sewer pipe networks rely largely on information from culture-based investigations. In this study, the succession of microbes associated with corroding concrete was characterized…
Graphene plasmonic structures with long-range layering periodicity are presented. Resonance energy scaling with the number of graphene layers involved in plasmonic excitation allows these structures to support multiple plasmonic modes that couple and hybridize due to their physical proximity. Hybridized states exhibit…
Carbon nanotube webs exhibit interesting properties when used as thermo-acoustic projectors. This work studies thermo-acoustic effect of these sound sources both in near and far field regions. Based on two alternative forms of the energy equation, we have developed a straightforward formula for calculation of pressure…
Abstract A three‐component platinum–ceria/graphene nanosheet hybrid (Pt–CeO2−x/GNS) was prepared through a facile one‐pot synthesis method and examined as an electrocatalysts for alcohol (methanol, ethanol, ethylene glycol, and glycerol) oxidation. The structures of the catalysts were characterized by using transmissi…
Abstract Charge‐balanced by protonated pyridine, four iodoargentate hybrids, [(Hpy)(Ag2I3)]n (1, 2D), {[(Hpy)2·dmf][Ag6I8]}n (2, 2D), {[(Hpy)2·H2O][Ag3I5]}n (3, 1D) and [(Hpy)(Ag5I6)]n (4, reported 3D) (Hpy+ = protonated pyridine, dmf = N,N‐dimethylformamide), were synthesized in the system comprising pyridine/AgI/HI/…
We report a mobility gradient of polymer chains in close proximity of a planar solid substrate in compressed carbon dioxide (CO 2 ) gas. A series of bilayers composed of bottom hydrogenated polystyrene (h-PS) and top deuterated PS (d-PS) layers were prepared on Si substrates. A high-pressure neutron reflectivity (NR)…
Abstract The intercalation of lithium into graphite was studied at temperatures between 400 and 550 ?C by heating mixtures of LiH and graphite powders with molar ratios 4:1, 1:1, and 1:6 under dynamic vacuum for periods between 1 and 72 h. These conditions probe the formation and thermal stability of metastable staged…
Anterior cruciate ligament (ACL) rupture is a common ligamentous injury often necessitating surgery. Current surgical treatment options include ligament reconstruction with autograft or allograft, which have their inherent limitations. Thus, there is interest in a tissue-engineered substitute for use in ACL regenerati…
For a better understanding of the SiC oxidation mechanism, we investigated differences in the oxidation process for surfaces with different crystal orientations. Real-time observations of oxidation processes for (0001) Si-face, (112¯0) a-face, and (0001¯) C-face substrates at various oxidation temperatures were perfor…
During the last decades, changes have been observed in the frequency of different histologic subtypes of lung cancer, one of the most common causes of morbidity and mortality, with a declining proportion of squamous cell carcinomas and an increasing proportion of adenocarcinomas, particularly in developed countries. T…
In this study, the application of hydrodynamic cavitation to improve the biodegradability of mature landfill leachate was investigated. Three configurations of cavitation device were examined and operational parameters of the process were selected. The study indicated that the orifice plate with a 3/10mm diameter coni…
The biaxial deformation of a ferritic sheet steel has been examined using high energy in situ X-ray diffraction. A purpose built biaxial loading mechanism was constructed to enable deformation across a wide range of strain ratios. Three nominal deformation conditions were compared: (1) uniaxial loading, ∊TD/∊RD=-ν, (2…
For materials that harbour a continuous phase transition, the susceptibility of the material to various fields can be used to understand the nature of the fluctuating order and hence the nature of the ordered state. Here we use anisotropic biaxial strain to probe the nematic susceptibility of URu2Si2, a heavy fermion…
A 120-mm wide amorphous ribbon of a Fe-Co-Si-B-P-Cu NANOMET® alloy has been successfully produced by a single roll melt spinning technique. The optimally annealed samples exhibited low coercivity (Hc) of 5–7 A/m and high saturation magnetic flux density (Bs) of 1.83 T. The plots of Hc and Bs vs. annealing temperature…
The apparent Sc(3+) adduct of [Fe(IV)(O)(TMC)](2+) (1, TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) has been synthesized in amounts sufficient to allow its characterization by various spectroscopic techniques. Contrary to the earlier assignment of a +4 oxidation state for the iron center of 1, we esta…
About 20 years ago, the first three-dimensional (3D) reconstructions at subnanometer (<10-Å) resolution of an icosahedral virus assembly were obtained by cryogenic electron microscopy (cryo-EM) and single-particle analysis. Since then, thousands of structures have been determined to resolutions ranging from 30 Å to ne…
In the last four decades, substantial advances have been done in the understanding of the electrical behavior of excitable cells. From the introduction in the early 70's of the Ion Sensitive Field Effect Transistor (ISFET), a lot of effort has been put in the development of more and more performing transistor-based de…
This Article reports the solvent-free synthesis and characterization of a number of different crystal forms of niclosamide (HNic), which is an API belonging to the Salicilamide class. The synthesized compounds are four new salt cocrystals ( KNic·HNic·H 2 O, KNic·HNic·3H 2 O, NaNic·HNic·3H 2 O, NaNic·HNic·2H 2 O ), a c…
