The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum via tunneling induced by a strong electric field. Unfortunately, as the required field strength is extremely large, this fundamental prediction of quantum field theory has not been verified experimentally yet. Here,…
Abstract The sensitivity study of propellants has been receiving heightened attentions from a lot of investigators. These propellants based on nitrocellulose are sensitive to accidental stimuli that result in catastrophic accidents. Thus energetic thermoplastic elastomers have been used as binders to replace some nitr…
The La-substitution and pressure effects on antiferromagnet CeCoSi with a tetragonal crystal structure were investigated in order to clarify the origin of the pressure induced ordered phase (PIOP) with an enormously high transition temperature of T0 ∼ 38 K. By substituting Ce with La, the PIOP shifts to high pressures…
Abstract Mn3O4 nanoparticle‐decorated carbon cloths are prepared as the electrodes for vanadium redox flow batteries. The Mn3O4 nanoparticles are prepared using a two‐step process, in which MnOOH nanoflakes are electrodeposited on the surface of the carbon cloth and subsequently converted to Mn3O4 nanoparticles by a t…
This study presents the theory for liquid–liquid phase separation for systems of molecules modeling monoclonal antibodies. Individual molecule is depicted as an assembly of seven hard spheres, organized to mimic the Y-shaped antibody. We consider the antibody–antibody interactions either through Fab, Fab′ (two Fab fra…
In this study, polyamide-aluminum foil-polypropylene (PA-Al-PP) composite films with different orientation status of the PP layer were prepared, and their morphology, tensile, peeling and heat seal behavior were studied. The comparative study of tensile and fracture behaviors of single-layer film of PA, Al and PP, as…
The highly hydrophobic poly(ether sulfone)/fluorinated silica (PES/fSiO 2 ) organic–inorganic composite membrane for sulfur dioxide (SO 2 ) desulfurization was prepared by incorporating the fSiO 2 particles on the PES membrane via sol–gel process and fluorination. The formation of PES/fSiO 2 organic–inorganic composit…
Maintaining cell viability within 3D tissue engineering scaffolds is an essential step toward a functional tissue or organ. Assessment of cell viability in 3D scaffolds is necessary to control and optimize tissue culture process. Monitoring systems based on respiration activity of cells (e.g., oxygen consumption) have…
Supported bimetallic nanoparticles have good activities in heterogeneous catalysis and electrocatalysts. Among those systems, PdAu shows improved stability and enhanced catalytic activity toward electrochemical reactions such as oxygen reduction, formic acid oxidation, and hydrogen evolution. The aim of this work was…
Abstract The electronic structure and magnetic properties of chalcopyrite Zn(Sn,TM)As 2 and (Zn,TM)SnAs 2 have been investigated by the Korringa–Kohn–Rostoker method combined with the coherent potential approximation within the local spin density approximation, where TM denotes a 3d transition metal element. We find t…
Among the recent advancements in lithium–oxygen (Li–O2) chemistries, redox mediators (RMs) have been revealed to play a significant role in decreasing overpotential on charging and in improving cycling performance. However, an intrinsic problem is redox shuttle of RMs, which leads to degraded RM utilization and induce…
The small interfering RNA (siRNA) is emerging as a potential therapeutic for the treatment of various diseases because of the targeted gene silencing capability. The suppression of p65 expression has shown great potential in various cancer treatments. However, various substantial obstacles limit its clinical applicati…
Spin-wave (SW) modes excited in cylindrical nanotubes of finite length were investigated using finite-element micromagnetic simulations. From the simulation results along with the relevant analytical interpretation, we found unique dynamic modes representative of a variety of standing SW modes. Those modes are control…
The chemical synthesis and crystallization steps were integrated successfully for directly producing a 1:1 cocrystal of sulfathiazole–theophylline and a 1:1 cocrystal of sulfathiazole–sulfanilamide. The benefits of this process intensification were the reduction of number of steps, and the amount of energy consumption…
H 2 S, a toxic gas present in raw natural gas and in oil fields, is converted to sulfur using the Claus process in sulfur recovery units. The low and fluctuating demand and sale price of sulfur and its increasing production due to the discovery of new sour fields have mandated optimization studies to reduce the produc…
Tensile mechanics of double-network (DN) hydrogels synthesized from 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and acrylamide (AAm) with different cross-link density of the first networks was studied after applying the freeze/thaw (F/T) process. When a DN hydrogel which exhibits necking upon applying a tensile l…
Abstract A near‐infrared (NIR) induced decomposable polymer nanocapsule is demonstrated. The nanocapsules are fabricated based on layer‐by‐layer co‐assembly of azobenzene functionalized polymers and up/downconversion nanoparticles (U/DCNPs). When the nanocapsules are exposed to 980 nm light, ultraviolet/visible photon…
Buckling, postbuckling, and nonlinear responses of composite cylindrical panels reinforced by single-walled carbon nanotubes (CNTs), supported by an elastic foundation, exposed to elevated temperature and axially compressed by uniform load are investigated in this article. Distribution of CNTs is uniform or graded in…
A new derivative of cellulose aerogel was prepared via functionalization of cellulose with dimercaprol. Dimercaprol, as a chelating agent of Au(III), was applied for the loading of Au(III) on cellulose aerogel. The new organogold compound after characterization was used as an efficient heterogeneous catalyst in the ox…
We report that the dynamic levitation force of bulk high temperature superconductors (HTS) in motion attenuates when exposed to an inhomogeneous magnetic field. This phenomenon has significant potential implications for the long-term stability and running performance of HTS in maglev applications. In order to suppress…
