We present a comparison among several fully-vectorial methods applied to basic scattering problem governed by the physics of electromagnetic interaction between subwavelength apertures in metal film. The modelled structure represents slit-groove silver film deposited on glass substrate. benchmarked methods, all which use in-house developed software, include broad range approaches from finite-element volume-integral and finite-difference time domain various types modal based different...
The application of wire grid polarizers as efficient polarizing beam splitters for visible light is studied. large differences between the transmissivity different polarizations are explained qualitatively by using theory metallic wave guides. results rigorous calculations obtained finite element method compared with experiments both classical and conical mount. Furthermore wire-grid in liquid crystal on silicon display systems considered.
To improve synergistic anticancer efficacy and minimize the adverse effects of chemotherapeutic drugs, temozolomide (TMZ) curcumin (CUR) co-loaded nanostructured lipid carriers (NLCs) were prepared by microemulsion in this study. And physicochemical properties, drug release behavior, intracellular uptake efficiency, vitro vivo TMZ/CUR-NLCs evaluated. showed enhanced inhibitory on glioma cells compared to single loaded NLCs, which may be owing that quickly released CUR can sensitize cancer...
Enhanced angiography based on magnetic resonance imaging (MRI) has emerged as a noninvasive, robust, and high-resolution technique for the clinical evaluation of vascular diseases. However, effects Gd-chelating contrast agents are unsatisfactory MRI enhancement owing to their short blood half-life caused by rapid extravasation, especially in microvessels. To address these issues, nanoprobes red cell membrane-coated ultrasmall NaGdF4 nanoparticles that exhibit much higher longitudinal molar...
We report on the surprisingly strong, broadband emission of coherent terahertz pulses from ultrathin layers semiconductors such as amorphous silicon, germanium and polycrystalline cuprous oxide deposited gold, upon illumination with femtosecond laser pulses. The strength is surprising because materials are considered to be bad (amorphous silicon oxide) or fair germanium) emitters at best. show that partly explained by cavity-enhanced optical absorption. This forces most light absorbed in...
A series of novel pyrazolyl acrylonitrile derivatives was designed, targeting Tetranychus cinnabarinus, and synthesized. Their structures were identified by combination 1H NMR, 13C MS spectra. The compounds 18 19 further confirmed X-ray diffraction. Extensive greenhouse bioassays indicated that compound exhibits excellent acaricidal activity against all developmental stages T. which is better than the commercialized cyenopyrafen spirodiclofen. It shown acute toxicity to mammals quite low....
Curcumin (CM) has multiple pharmacological activities including anti-fungal activity, but its clinical application is limited due to low solubility in aqueous media, poor bioavailability and extensive first pass metabolism. We aimed resolve the limitation enhance antifungal activity of CM using nanotechnology. Using silk fibroin (SF) as a carrier, we fabricated curcumin-silk nanoparticles (CM-SF NPs) by solution enhanced dispersion supercritical CO₂ (SEDS) technique. The characterization...
Abstract Plasmon catalysis is an interesting technology concept for powering chemical processes with light. Here, we report the use of various Al 2 O 3 ‐supported Ru spheroidal nanoparticles as catalyst low‐temperature conversion CO and H to CH 4 (Sabatier reaction), using sunlight energy source. At high loadings (5.9 % w/w), observe a sharp increase in rate powered reaction when compared dark at same bed temperature. Based on our results exclude plasmon coupling cause, attribute enhancement...
Abstract Sunlight‐powered reduction of CO 2 to fuels and chemicals is a promising strategy close the carbon loop facilitate energy transition. In this research, we demonstrate that Au nanoparticles supported on TiO are an efficient plasmonic catalyst for sunlight‐powered reverse water‐gas shift (rWGS) reaction. A maximum production rate 429 mmol ⋅ g −1 h with selectivity 98 % apparent quantum efficiency 4.7 were achieved using mildly concentrated sunlight (1.44 W cm −2 equals 14.4 sun). The...
In this study, a switchable coding metasurface was demonstrated in the terahertz (THz) frequency range to realize dynamic beam steering based on Dirac semimXetal. The relative phase delay of proposed metamaterials unit cell can be actively controlled by changing Fermi level (EF) semimetal film (DSF). For 1-bit metasurface, units with '0′ and '1′ states switched on/off 1.46–2 THz EF value DSF. numbers propagation direction reflected waves such metasurfaces engineered at will. Moreover,...
Aluminum (Al) and its alloys have been widely used in daily life, but the absence of antibacterial properties makes them potential vectors for bacterial transmission. In this study, an Ag-doped TiO2 coating was successfully prepared on porous surface etched Al foil using sol-gel method. The results indicated that layer allowed gel to permeate through holes, thereby forming interface carrying these agents with a thickness about 10 μm. Ag dopant promoted transformation titania from rutile...
Plasmonic CO2 methanation using γ-Al2O3-supported Ru nanorods was carried out under continuous-flow conditions without conventional heating, mildly concentrated sunlight as the sole and sustainable energy source (AM 1.5, irradiance 5.5–14.4 kW·m−2 = suns). Under 12.5 suns, a conversion exceeding 97% achieved with complete selectivity towards CH4 stable production rate (261.9 mmol·gRu−1·h−1) for at least 12 h. The showed an exponential increase increasing light intensity, suggesting that...
Among the bioactive compounds, lipid-soluble tanshinone is present in Salvia miltiorrhiza , a medicinal plant species. While it known that ethephon has ability to inhibit tanshinones biosynthesis S. hairy root, however underlying regulatory mechanism remains obscure. In this study, using transcriptome dataset of root induced by ethephon, an ethylene-responsive transcriptional factor EIN3-like 1 ( SmEIL1 ) was identified. The protein found be localized nuclei, and confirmed transient...

To date, large number manuscripts have been published on optics nanoshells. Few these, however, address effect particle size distribution metal shell imperfections resonance. Both inherent chemical synthesis therefore extent unavoidable. It vital importance understand their resonance, since this...
Hyperbolic metamaterials (HMMs) are anisotropic materials with a permittivity tensor that has both positive and negative eigenvalues. Here we report by using type II HMM as cladding material, waveguide only supports higher-order modes can be achieved, while the lower-order become leaky absorbed in cladding. This counter-intuitive property lead to novel application optical communications photonic integrated circuits. The loss our insulator-HMM (HIH) is smaller than of similar guided...
