Chiral metamaterials (CMMs) are widely used to implement devices that transform the polarization of an incident electromagnetic wave, such as polarization rotators and linear to circular converters, but rarely used as circular polarization converters. This letter presents a CMM that changes the handedness of a circula…
The gold standard of natural nacre provides the inspiration for assembling bioinspired nanocomposites.
A supra-amphiphilic system with a tunable supra-amphiphilic type and self-assembled morphology was constructed and controlled via light and host-guest interactions based on a water-soluble pillar[5]arene and a stiff-stilbene.
A novel method is presented to outcouple high spatial frequency (large-k) waves from hyperbolic metamaterials (HMMs) without the use of a grating. This approach relies exclusively on dispersion engineering, and enables preferential power extraction from the top or from the side of a HMM. Multilayer (ML) HMMs are shown…
A ferrocenecarboxylate-functionalized titanium-oxo cluster [Ti <sub>6</sub> (μ <sub>3</sub> -O) <sub>6</sub> (OiPr) <sub>6</sub> (O <sub>2</sub> CFc) <sub>6</sub> ] was synthesized, in which the ferrocene wheel performs as a sensitizer for photocurrent response.
Er <sup>3+</sup> concentration had significant influences on temperature sensitivity. The sample with a low concentration of Er <sup>3+</sup> had high temperature sensitivity.
Recombination dynamics during photoluminescence (PL) in two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are complicated and can be easily affected by the surroundings because of their atomically thin structures. Herein, we studied the excitation power and temperature dependence of the recom…
from a solution. Theoretical calculations on a model system have been performed to investigate the electronic spectral transitions.
A series of <italic>N</italic> -alkylated 1,4-dihydropyridine derivatives were reported to exhibit polymorphic and mechanochromic properties.
Motivated by the development of lubricant-infused slippery surfaces, we study a sessile drop of a nonvolatile (ionic) liquid which is embedded in a slowly evaporating lubricant film (n-decane) on a horizontal, planar solid substrate. Using laser scanning confocal microscopy we imaged the evolution of the shape of the…
Biochar/wood/plastic composites were prepared with different biochar content by the extrusion method, and the mechanical properties and flame retardant properties were tested. The study indicated that: with the increase of biochar content, the mechanical properties of the composites tended to rise at first and then fe…
Aminoclay was used as a scaffold for lanthanide complexes and dye molecules for light harvesting applications.
The reaction mechanism and properties of a catalytic process are primarily determined by the interactions between reacting species and catalysts. However, the interactions are often challenging to be experimentally measured, especially for unstable intermediates. Therefore, it is of significant importance to establish…
Fluorescent silver nanoparticles have been employed in an immunoassay to detect HIV p24 antigen with high sensitivity in the linear range of 10–1000 pg mL <sup>−1</sup> .
topography is a common theme for nucleobases. We also discuss how the triplet-state topography may be used to control the singlet oxygen yield, aiming at different medical applications.
A tunable metamaterial absorber based on the liquid crystal intended for F frequency band is presented. The proposed absorber was analyzed both numerically and experimentally. The conducted analysis has shown that the bias voltage affects the orientation of the nematic liquid crystal embedded in the mesh voids and cau…
The preparation of 70% CoFe 2 O 4 /30% SiO 2 (wt%) nanocomposites by sol-gel method using three short chain diols (1,2-ethanediol, 1,3-propanediol, and 1,4-butanediol) as chelators was studied. The Fourier transformed infrared spectra and X-ray diffraction patterns were used to confirm the formation of nanocomposites.…
In the present work, we have explored the growth of ZnO nanorods from a zinc acetate precursor by a thermal decomposition process at 300 °C. Our key observation indicates that a lower heating rate favors the formation of ZnO nanorods while faster heating rates favor the formation of a mixture of ZnO nanorods and nanop…
The enzymatic polycyclization reactions catalyzed by oxidosqualene (OXSQ) cyclases (OSCs) proceed with complete regio- and stereospecificity, leading to the formation of new C-C bonds and chiral centers and to the generation of diverse polycyclic sterols and triterpenoids. The diverse structural array is remarkable, a…
Amorphous chalcogenide semiconducting materials are very sensitive to electromagnetic radiation and are useful for infrared optics and play a pivotal role in modern technology.
