A novel polysaccharide, here named DP1, was isolated from the fruiting body of Dictyophora indusiata using a water extraction method. Structure characterization revealed that DP1 had an average molecular weight 1132 kDa and consisted glucose (56.2%), galactose (14.1%), mannose (29.7%). The main linkage type were proven to be (1 → 3)-linked α-l-Man, 2,6)-linked α-d-Glc, 6)-linked β-d-Glc, β-d-Gal, β-d-Man by periodate oxidation–Smith degradation nuclear magnetic resonance analysis....
Abstract Micromanipulation and biological, material science, medical applications often require to control or measure the forces asserted on small objects. Here, we demonstrate for first time microprinting of a novel fiber-tip-polymer clamped-beam probe micro-force sensor examination biological samples. The proposed consists two bases, clamped beam, force-sensing probe, which were developed using femtosecond-laser-induced two-photon polymerization (TPP) technique. Based finite element method...
We propose previously unknown allotropes of phosphorus carbide (PC) in the stable shape an atomically thin layer. Different geometries, which result from competition between sp2 bonding found graphitic C and sp3 black P, may be mapped onto 2D tiling patterns that simplify categorizing structures. Depending on category, we identify 2D-PC structures can metallic, semi-metallic with anisotropic Dirac cone, or direct-gap semiconductors their gap tunable by in-layer strain.
In analogy to III-V compounds, which have significantly broadened the scope of group IV semiconductors, we propose IV-VI compounds as isoelectronic counterparts layered V semiconductors. Using {\em ab initio} density functional theory, study yet unrealized structural phases silicon mono-sulfide (SiS). We find black-phosphorus-like $\alpha$-SiS be almost equally stable blue-phosphorus-like $\beta$-SiS. Both and $\beta$-SiS monolayers display a significant, indirect band gap that depends...
A simple compact planar pattern-reconfigurable antenna based on arc dipoles is proposed in this letter. The consists of four identical and a broadband reconfigurable feeding network, which are printed the bottom top layers substrate, respectively. By switching on/off states p-i-n diodes, integrated different modes with endfire radiation patterns can be obtained azimuthal plane. simulated, fabricated, measured. Experimental results indicate that achieves bandwidth 33.6% (2.25-3.16 GHz) for...
The amalgamation of thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) properties, termed AIE-TADF, is a promising strategy to design novel robust luminescent materials. Herein, we transform 2,3,4,5,6-penta(9H-carbazol-9-yl)benzonitrile (5CzBN) from an ACQ molecule into AIEgen by simply decorating the 5CzBN core with alkyl chain-linked spirobifluorene dendrons. By increasing number flexible dendrons, these materials can not only show obvious AIE-TADF...
Strategies to enhance the ratio of molecular horizontal emitting dipole orientation (Θ∥ ) for thermally activated delayed fluorescence (TADF) emitters have unlocked full potential efficiencies evaporated devices, which, however, remain elusive solution-processed ones. Here, a strategic design solution processable TADF featuring high Θ∥ s is proposed by attaching flexible chains ended with bipolar 9,9'-spirobi[fluorene] subunits as anchoring groups onto core. It's unveiled that not only via...
Abstract Light has been sought and explored by human since ancient times. As the most important form of light, fluorescence is significant to applications in bioimaging optoelectronic devices. However, quenching problem constitutes a serious bottleneck materials creation. Inspired from core–shell structure nature, we report an effective strategy overcome this long‐standing utilizing molecular structure. With emissive core multifunctional shell fragments, these compounds show...
Highly porous boron nitride nanosheets (BNNSs) were tested as a re-usable adsorbent for the removal of pharmaceuticals from aqueous solution. The BNNSs exhibit both unprecedentedly high adsorption capacities and excellent recyclability while maintaining their capacity by simple regeneration process. These advantages render promising material water remediation applications.
Few-layer black phosphorus (BP) which exhibits excellent optical and electronic properties, has great potential applications in nanodevices. However, BP inevitably suffers from the rapid degradation ambient air because of high reactivity P atoms with oxygen water, greatly hinders its wide applications. Herein, we demonstrate electrostatic functionalization as an effective way to simultaneously enhance stability dispersity aqueous phase exfoliated few-layer BP. The poly dimethyldiallyl...
As an alternative to atomistic calculations of long-wavelength acoustic modes atomically thin layers, which are known converge very slowly, we propose a quantitatively predictive and physically intuitive approach based on continuum elasticity theory. We describe layer, independent its thickness, by membrane characterize elastic behavior $(3\ifmmode\times\else\texttimes\fi{}3)$ matrix as well the flexural rigidity. present simple quantitative expressions for frequencies modes, determine using...
