Photon loss in optical fibers prevents long-distance distribution of quantum information on the ground. Quantum repeater is proposed to overcome this problem, but communication distance still limited so far because system complexity scheme. Alternative solutions include transportable memory and quantum-memory-equipped satellites, where long-lived memories are key components realize global communication. However, longest storage time demonstrated approximately 1 minute. Here, by employing a...
A novel approach to constructing three-dimensional (3D) highly ordered structural polyaniline–graphene bulk hybrid materials was proposed for high performance supercapacitor electrodes, in which a functional molecule, sulfonated triazine (ST), introduced and adsorbed on graphene sheets via hydrogen bonding π–π stacking interactions. The aim of adding ST is achieve better dispersion nanosheets water, subsequently induce heterogeneous nucleation polyaniline (PANI) through electrostatic Thus,...
We report dynamic Monte Carlo simulations of polymer crystallization confined in thin films thicknesses comparable to the polymer−coil sizes. considered two contrasting affinities walls polymers, namely sticky that arrest movement polymers contact with substrate (such adsorbed layers allow avoid dewetting) and slippery reflecting neutral repulsion polymers. found at high temperatures slightly enhance rate decrease film thickness, surface-assisted crystal nucleation results dominant edge-on...
This paper describes the development of a high density consensus genetic linkage map turbot (Scophthalmus maximus L.) family composed 149 mapping individuals using Single Nucleotide Polymorphisms (SNP) developed restriction-site associated DNA (RAD) sequencing technique with restriction enzyme, PstI. A total 6,647 SNPs were assigned to 22 groups, which is equal number chromosome pairs in turbot. For first time, average marker interval reached 0.3958 cM, approximately 0.1203 Mb genome. The...
Precise stacking of distinct two‐dimensional (2D) rigid slabs to build heterostructures has renewed the portfolio 2D materials, e.g., magic‐angle graphene, due emergence exotic physical properties. Recently, single‐crystal layered perovskites have emerged as an exciting branch, while it remains scarce achieve strong ferroelectricity in this new heterostructure family. Here, we present first ferroelectric perovskite single crystal, (EA3Pb2Br7)EA4Pb3Br10 (1, EA = ethylamine), by precisely...
Spintronics has long been an exciting branch of condensed matter science, among which the spin splitting energy bands in inversion asymmetric material endows circular photogalvanic effects (CPGE) toward high‐performance spin‐based optoelectronic devices. Here, we have successfully achieved gate‐tunable CPGE a biaxial perovskite ferroelectric (n‐heptanamine)2CsPb2Br7 (1), involving broken symmetry from its spontaneous polarization. Strikingly, under left‐ and right‐circularly polarized light,...
Abstract The regulation of body temperature in dynamic environments is greatly significant for maintaining human thermal comfort. As the second skin body, clothing performs a vital role personal management. However, conventional textiles are unable to effectively regulate extreme environments. Therefore, functional and personalized materials gradually entering horizons.

Abstract In optical metrological protocols to measure physical quantities, it is, in principle, always beneficial increase photon number n improve measurement precision. However, practical constraints prevent the arbitrary of due imperfections a detector, especially when detector response is dominated by saturation effect. this work, we show that modified weak protocol, namely, biased significantly improves precision metrology presence This method detects an ultra-small fraction photons...
We performed molecular simulations of polymer crystallization confined in rigid nanotubes. found that the neutrally repulsive walls nanotubes enhance crystal nucleation. This enhancement gives uniform orientation parallel to tube axis at high temperatures. However, nanotube are wetted by polymer, i.e. 'sticky' walls, switch dominant from perpendicular. Since only perpendicularly oriented crystals can grow along give crystallinities, sticky provide a promising route towards mass production...
Abstract High-power terahertz (THz) quantum cascade laser, as an emerging THz solid-state radiation source, is attracting attention for numerous applications including medicine, sensing, and communication. However, due to the sub-wavelength confinement of waveguide structure, direct beam brightness upscaling with device area remains elusive several mode competition external optical lens normally used enhance brightness. Here, we propose a metallic photonic crystal resonator phase-engineered...
We studied the athermal relaxation of bulk extended chains and isothermal crystallization in an intermediately relaxed melt by means dynamic Monte Carlo simulations lattice−polymer systems. The contained a memory chain orientations but no more crystalline order. found that is continuous homogeneous among chains, its rate depends on length. orientational significantly enhances crystallization. Nevertheless, precursor occurs uniform lengths. But, binary blend different lengths, oriented long...
We report dynamic Monte Carlo simulations of immiscible binary polymer blends, which exhibit weakly enhanced crystal nucleation near interfaces between two phase-separated polymers. found that this enhancement is not accompanied by any preferred orientation, implying its origin mainly enthalpic rather than entropic nature. Mean-field theory blends predicts for polymers the melting point crystallizable component increases upon dilution in other component, while it normally decreases miscible...
The spatiotemporal evolution of photogenerated charge carriers on surfaces and at interfaces photoactive materials is an important issue for understanding fundamental physical processes in optoelectronic devices advanced materials. Conventional optical probe-based microscopes that provide indirect information about the dynamic behavior are inherently limited by their poor spatial resolution large penetration depth. Herein, we develop ultrafast scanning electron microscope (USEM) with a...
Abstract We demonstrated a scheme of phase-locked terahertz quantum cascade lasers (THz QCLs) array, with single-mode pulse power 108 mW at 13 K. The device utilizes Talbot cavity to achieve phase locking among five ridge first-order buried distributed feedback (DFB) grating, resulting in nearly times amplification the power. Due optimum length depends on wavelength, combination DFB grating leads better than multimode Fabry−Perot (F−P) cavities. facet reflects light back array direction and...
