A switchable magnetic metamaterial is demonstrated via reshaping micromachined molecules. It experimentally verified that the effective permeability can be switched from negative to positive near resonant frequency. The micromachining technology offers a powerful platform for metamaterials and provides more degrees of freedom design, easy fabrication, large tunability.
A metal-insulator-semiconductor (MIS) photosystem based on covalent organic framework (COF) semiconductors was designed for robust and efficient hydrogen evolution under visible-light irradiation. maximal H2 rate of 8.42 mmol h-1 g-1 a turnover frequency 789.5 were achieved by using MIS prepared electrostatic self-assembly polyvinylpyrrolidone (PVP) insulator-capped Pt nanoparticles (NPs) with the hydrophilic imine-linked TP-COFs having =C=O-H-N= hydrogen-bonding groups. The hot π-electrons...
Abstract A micromachined reconfigurable metamaterial is presented, whose unit cell consists of a pair asymmetric split‐ring resonators (ASRRs); one fixed to the substrate while other patterned on movable frame. The and supporting structures (e.g., microactuators, anchors, frames, etc.) are fabricated silicon‐on‐insulator wafer using deep reactive‐ion etching (DRIE). By adjusting distance between two ASRRs, strength dipole–dipole coupling can be tuned continuously actuators this enables...
Photocatalytic water purification utilizes light to degrade the contaminants in and may enjoy many merits of microfluidics technology such as fine flow control, large surface-area-to-volume ratio self-refreshing reaction surface. Although a number microfluidic reactors have been reported for photocatalysis, there is still lack comprehensive review. This article aims identify physical mechanisms that underpin synergy and, based on which, review photocatalytic reactors. These microreactors...
Transformation optics represents a new paradigm for designing light-manipulating devices, such as cloaks and field concentrators, through the engineering of electromagnetic space using materials with spatially variable parameters. Here we analyse liquid flowing in an optofluidic waveguide type controllable transformation medium. We show that laminar flow channel exhibits dielectric properties support novel wave-focussing interference phenomena, which are distinctively different from discrete...
Optofluidics may hold the key to greater success of photocatalytic water treatment. This is evidenced by our findings in this paper that planar microfluidic reactor can overcome limitations mass transfer and photon previous reactors improve photoreaction efficiency more than 100 times. The microreactor has a chamber (5 cm×1.8 cm×100 μm) enclosed two TiO(2)-coated glass slides as top cover bottom substrate microstructured UV-cured NOA81 layer sealant flow input∕output. In experiment, achieves...
The murine coronavirus mouse hepatitis virus (MHV) induced the expression of type I interferon (alpha/beta [IFN-alpha/beta]) in oligodendrocytic N20.1 cells. This induction is completely dependent on replication, since infection with UV light-inactivated could no longer induce IFN-alpha/beta. We show that MHV activated both transcription factors, IFN regulatory factor 3 (IRF-3) and nuclear kappaB (NF-kappaB), as evidenced by phosphorylation translocation IRF-3 an increased promoter binding...

Metamaterial (MM) assisted terahertz (THz) label-free biosensing has promising applications. However, the sensitive THz detection of highly absorptive liquid samples remains challenging. Here, we present a novel multi-microfluidic-channel MM biosensor for sensing small-volume samples. The multichannels are set mostly in strong electric field enhancement area MM, which significantly decreases liquid's amount and enhances interaction between targets wave (thus increasing sensitivity). results...
Abstract Food production in green crops is severely limited by low activity and poor specificity of D-ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) natural photosynthesis (NPS). This work presents a scientific solution to overcome this problem immobilizing RuBisCO into microfluidic reactor, which demonstrates continuous glucose precursor at 13.8 μmol g −1 min from CO 2 ribulose-1,5-bisphosphate. Experiments show that the immobilization significantly enhances enzyme stabilities...
D-π-A type 4-((9-phenylcarbazol-3-yl)ethynyl)-N-dodecyl-1,8-naphthalimide (CZNI) with a large dipole moment of 8.49 D and A-π-A bis[(4,4'-1,8-naphthalimide)-N-dodecyl]ethyne (NINI) negligible 0.28 D, were smartly designed synthesized to demonstrate the evidence molecular as dominant mechanism for controlling charge separation organic semiconductors. In aqueous solution, these two novel naphthalimides can self-assemble form nanoribbons (NRs) that present significantly different traces exciton...
Abstract Plasmon‐enhanced photocatalysis has emerged as a promising technology for solar‐to‐chemical energy conversion. Compared to isolated or disordered metal nanostructures, by controlling the morphology, composition, size, spacing, and dispersion of individual nanocomponents, plasmonic nanostructure arrays with coupling architectures yield strong broadband light‐harvesting capability, efficient charge transfer, enhanced local electromagnetic fields, large contact interfaces. Although...

Taking nylon kernmantle for high-altitude fall protection commonly used in aerial work rock climbing as research object, response behavior of when drop mass is dropped once repeatedly systematically studied, are discussed. Further, evolution elastic...
A cellular protein, previously described as p35/38, binds to the complementary (−)-strand of leader RNA and intergenic (IG) sequence mouse hepatitis virus (MHV) RNA. The extent binding this protein IG sites correlates with efficiency subgenomic mRNA transcription from that site, suggesting it is a requisite factor. We have purified determined by partial peptide sequencing heterogeneous nuclear ribonucleoprotein (hnRNP) A1, an abundant, primarily protein. hnRNP A1 shuttles between nucleus...
