There is an urgent need for infrared (IR) detection systems with high-level miniaturization and room-temperature operation capability. The rising star of two-dimensional (2D) semimetals extraordinary optoelectronic properties can fulfill these criteria. However, the formidable challenges regard to large-scale patterning substrate-selective requirements limit material deposition options device fabrication. Here, we report a convenient straightforward eutectic-tellurization transformation...
The fast and inexpensive production of single-crystal silicon nanowires, which circumvents the use lithography, is achieved by pyrolysis silane in nanochannel alumina with a gold catalyst. nanowires (see Figure for an SEM image) are very straight, not intertwined, uniform diameter length. They should be good candidates field emitter arrays high tip density.
We demonstrate mid-infrared ultraflat broadband supercontinuum (SC) generation in a 40 cm long tapered fluorotellurite fiber pumped by Raman soliton source. By tapering the end of large-core-diameter fiber, dispersion is regulated and nonlinear effect enhanced, which effectively extends SC spectral range increases flatness. Finally, we obtained an light source with from 1.8 to 4.7 μm; 10 dB bandwidth completely covers 1.88–4.22 μm, has farthest flat edge fibers. The output power laser about...
Bi2WO6 films with nanoleaflike structures, which are directly grown on a fluorinated tin oxide substrate, were first realized by solvothermal method. Because of the peculiar leaflike structure, exhibited excellent photocatalytic activity in degradation phenol, is widely used but slowly degradable natural environment. The phenol could be further improved photoelectrocatalytic process, along sharp decrease total organic carbon. According to experimental results, possible mechanism removal was...
We have synthesized high-quality 2D, quasi-2D and 3D (PEA) 2 (CsPbBr 3 ) n −1 PbBr 4 perovskites. Stable mode-locked ultrashort pulses are generated based on these three saturable absorbers.
Escherichia albertii is an emerging member of the Enterobacteriaceae causing human and animal enteric infections. Antimicrobial resistance among enteropathogens has been reported to be increasing in past years. The purpose this study was investigate antibiotic genes E. isolated from Zigong city, Sichuan province, China. susceptibility 21 antimicrobial agents determined by Kirby-Bauer disk diffusion method. highest prevalence tetracycline with a rate 62.7%, followed nalidixic acid...
Chronic inflammatory pain is the highest priority for people with osteoarthritis when seeking medical attention. Despite availability of NSAIDs and glucocorticoids, central sensitization peripheral make increasingly difficult to control. Previous studies have identified ubiquitination system as an important role in chronic pain. Our study displayed that E3 ubiquitin ligase tripartite motif-containing 14 (Trim14) was abnormally elevated serum patients pain, degree positively correlated Trim14...
A laminated micropolarizer of Pb nanowire arrays was fabricated within an anodic alumina membrane (AAM) by anodization the pure Al foil and subsequent electrodeposition Pb. X-ray diffraction, scanning electron microscopy, transmission selected-area high-resolution microscopy investigations reveal that ordered nanowires are essentially single crystal, have average diameter 40 nm. Spectrophotometry measurements show embedded in AAM can only transmit polarized light vertical to wires. An...
Bacteria in root nodules of legumes play important roles promoting plant growth. In this study, we investigated nodule-associated bacteria isolated from leguminous plants along an elevation gradient on the northern slope Kunlun Mountains, China, using a cultivation approach. total, 300 isolates were obtained seven legume species within six ecological zones. Isolates identified based 16S rRNA gene phylogenetic analysis and potential rhizobia further rec A phylogeny. Among isolates, Bacillales...
The first and efficient total synthesis of (±)-dasyscyphin D was achieved in 9 steps with 22.6% overall yield. key involved a PtCl2-catalyzed pentannulation reaction acid-catalyzed double Robinson annulations.
Superhydrophilic and superhydrophobic surfaces exhibit numerous industrial applications such as self-cleaning, antifogging, anti-icing, electrowetting, photocatalysis. A surface with reversible wetting behaviors that can be controlled by external field is both scientifically technologically of importance. Light a major trigger for many natural processes. We report here an intelligent remote technology based on alternative UV near-infrared (NIR) irradiation enables dynamical wettability...
Yttrium iron garnet (YIG) is a potential matrix for immobilizing high-level radioactive waste (HLW) due to its high actinide solubility and chemical flexibility. In this study, Ce was employed as surrogate of Pu. A series Y3-xCexFe5O12 (0 ≤ x 1) samples were prepared by solid-state sintering at 1400°C investigate the solubility, microstructure, durability Ce-doped YIG. The X-ray diffraction (XRD) scanning electron microscopy (SEM) results showed that in single 32 mol% synthesis temperature...
Abstract Background Animal studies show that Catha edulis inhibits gastrointestinal tract motility. However, there is little or no information on its effect colon motility and the mechanism of action active constituents responsible for this effect. This study therefore attempted to discern effect, suggest mechanism, identify compounds from crude extract. Methods A extract was fractionated subfractionated using column chromatography HPLC. The activity all fractions subfractions evaluated rat...
Abstract A series of 4‐phosphoryl substituted 1,3‐oxazole are prepared conveniently by reaction diethyl 1‐diazo‐2‐oxo‐alkylphosphonates and aromatic nitriles in the presence a catalytic amount rhodium(II) acetate.
As artificial materials composed of subwavelength structures, metasurfaces have a strong ability to control linear and nonlinear light fields, which greatly promotes the development nanophotonics. Recently, plasmonic been proven behave as saturable absorbers (SAs) with modulation performance much higher than that other SAs, exhibiting excellent polarization transfer functions. However, due dependence resonance, working bandwidth metasurface saturated is usually very narrow, not favorable for...
