Electrospinning technique has excellent advantages such as tunable functionality, thin fibers with large surface areas, ease of processing and good physical properties. Electrospinning provides wide usage area with these advantages in biomedical applications. Polylactic acid (PLA) is a biodegradable and biocompatible…
ABSTRACT We investigated how end-functionalized solution styrene–butadiene rubber (SSBR) affects the vulcanizate structures and the physical properties of silica-filled vulcanizates using non-functionalized and end-functionalized SSBRs with aminopropylalkoxysilane. Two silane agents were used. Triethoxy(octyl)silane w…
This article studies the correlation between the tensile strength and the chemical composition of basalt fiber roving and analyzes rovings with different chemical compositions to derive equations that predict the roving strength. The tensile properties of different types of basalt fiber roving that were impregnated wi…
Conjugated Möbius metalla-aromatic “carbolong” is incorporated into polymers to achieve spatially resolved, repeated and fast healing through a photothermal effect.
A refractive index (RI) sensor which contains a dielectric cavity composed of two parallel planar waveguide gratings (WGGs) is proposed. Reflection and transmittance through stacked gratings are studied after converting the diffraction problem into the two coupled resonances. The method of analysis is applied to estim…
A photochemical reaction in which the imidazole ring is opened under UV irradiation to generate highly luminescent benzoylimino group by O2 has been discovered. This photochemical reaction displays great potential for applications that use a fluorescent probe as a oxygen sensor; it has a lowest detectable volume ratio…
Abstract A facile procedure towards the fabrication of highly reproducible, large area surface‐enhanced Raman scattering (SERS) active substrates through integration of Langmuir–Blodgett and self‐assembly technique has been reported. The plasmonic architectures of the substrates can be tuned at will to control the hot…
Reliable fabrication of gold nanoparticles with desirable size, geometry and spatial arrangement is essential for plasmonic applications. A common fabrication flow usually involves electron-beam lithography and a vacuum-evaporation-based lift-off process or etching. In this work, we evaluate an alternative approach to…
Homojunctions comprised of transition-metal dichalcogenides (TMD) polymorphs are attractive building blocks for next-generation two-dimensional (2D) electronic circuitry. However, the synthesis of such homojunctions, which usually involves elaborate manipulation at the nanoscale, still remains a great challenge. Herei…
Abstract One of the challenges for multiphase materials is the improvement of the interconnectivity of their separate phases. A promising route toward excellent adhesion is molecular interdiffusion, in which molecules are transferred to enable physical interaction. In the present work, a novel straightforward and dire…
Four different model compounds were synthesized and utilized in this research to relate inhibitor alkyl tail length to changes in the activation energy of the electrochemical process associated with CO2 corrosion of an API 5L X65 steel at pH 4.0. The molecular structure of the model compounds was composed of the same…
A novel strategy for the surface functionalization of emulsion-templated highly porous (polyHIPE) materials as well as its application to in vitro 3D cell culture is presented. A heterobifunctional linker that consists of an amine-reactive N-hydroxysuccinimide ester and a photoactivatable nitrophenyl azide, N-sulfosuc…
Emamectin benzoate (EB), a widely used pesticide, is prone to decomposition by ultraviolet light and suffers from the corresponding loss of efficacy. The timed release of EB based on microspheres is one of the effective methods to solve this issue. As a non-toxic cellulose ester, cellulose acetate butyrate (CAB) is re…
The flow within microscopic indentations filled with a lubricant fluid is studied by varying viscosity ratio, surface tension, and lubricant-to-working-fluid volume fraction. This yields protrusion heights that readily quantify the drag reduction of a lubricant-impregnated microstructured surface.
Polyphosphonium was facilely grafted onto HNTs in an aqueous phase by a one-step method initiated by Ce(iv) at a mild temperature. The modified HNTs were immersed in a sodium alginate solution to achieve a uniform hydrogel that shows desirable antibacterial activity.
A series of mononuclear salen–sodium anions, as the first examples, were synthesized with tetra-alkyl ammonium as a counterpart cation. These complexes are efficient catalysts for the isoselective ring-opening polymerization of rac -lactide; the molecular weights of polymers are under control and molecular weight dist…
Abstract Discrete π‐conjugated zinc porphyrin nanotubes are investigated as molecular analogues of carbon nanotubes. These porphyrin nanotubes have a diameter of 2.4 nm (Zn–Zn distance) and lengths of up to 3.6 nm, measured to the van der Waals surfaces of the outer β‐pyrrole hydrogen atoms, or 4.5 nm measured to the…
Black phosphorus (BP) has received much attention owing to its fascinating properties, such as a high carrier mobility and tunable band gap. However, these advantages have been overshadowed by the fast degradation of BP under ambient conditions. To overcome this obstacle, the exact degradation mechanisms need to be un…
In this paper, we propose a compact, lightweight, and easy-to-fabricate Hilbert curve-based metasurface resonator that can effectively increase the sensitivity (radio frequency (RF) field intensity) and penetration depth of an RF coil for 7-T magnetic resonance imaging scanner. A circuit model is proposed to accuratel…
