We report a large and nonvolatile bipolar-electric-field-controlled magnetization at room temperature in Co(40)Fe(40)B(20)/Pb(Mg(1/3)Nb(2/3))(0.7)Ti(0.3)O(3) structure, which exhibits an electric-field-controlled looplike magnetization. Investigations on the ferroelectric domains crystal structures with situ electric fields reveal that effect is related to combined action of 109° ferroelastic domain switching absence magnetocrystalline anisotropy Co(40)Fe(40)B(20). This work provides route...

The mechanism for this magnetoelectric (ME) coupling can be understood combination ultra-high value anisotropic in-plane piezoelectric coefficients...
Reversible electro-optical switching is achieved in a facile manner by dispersing small amount of ZnS nanoparticles into blue phase I (BPI). The hysteresis so that it can be considered as hysteresis-free at 0.5–0.7 wt% doping level, and the on-state voltage much lower than polymer-stabilized BPI.
Electro-optical switching with low voltage, free hysteresis and fast response speed is achieved in a facile manner by dispersing small amount of ferroelectric nanoparticles (NPs) into blue phase liquid crystal. The large dipole moment NPs contributes to the hysteresis-free switching, whereas voltage operation results from introduction properties inherent NPs.
Thiophene-based bent-shaped mesogens were firstly applied to extend the blue phase range. And electro-optical performances of liquid crystalline composites doped with different concentration these also explored by incorporating in-plane electric field geometry.
Electro-optical switching with low voltage, no hysteresis and fast response speed is achieved in polymer-stabilized nanoparticle-enriched blue phase liquid crystals a wide temperature range, it found that the benefits from combined method are more than simple addition of polymer stabilization nanoparticle dispersion.
The in vivo monitoring of ascorbic acid (AA) following physiological and pathological events is great importance because AA plays a critical role brain functions. conventional electrochemical sensors (ECSs) usually suffered from poor selectivity sluggish electron transfer kinetics for cerebral oxidation. exploitation ECSs adapt to the detection (ECD)-microdialysis system, here we reported facile ratiometric sensor (RECS) vivo/online repetitive measurements microdiaysate. were constructed by...
Several kinds of tolane cyano derivatives with different lateral fluoro substituents are doped chiral additives to induce the blue phase (BP). Fluoro found exert a great effect on BP ranges for biphenyl mesogens. The laterally difluorinated compounds exhibit wider than their corresponding mono-fluorinated homologues when equal dopant is added, while non-fluorinated show direct isotropic (Iso) nematic (N*) transitions, even in highly systems. By adjusting concentrations ISO(6OBA)2 fluorinated...
Abstract A series of symmetrically 2,5-disubstituted 1,3,4-oxadiazoles with different rigid cores were synthesised under the microwave irradiation based on green chemistry and atom economy. The induced blue phase (BP) behaviours these bent-shaped compounds investigated after blending them a high twisted power chiral dopant or doping into nematic liquid crystal (N*LC). It was found that BP ranges varied greatly difference in 1,3,4-oxadiazoles, molecules higher miscibility molecular...

An experiment about perceived conducted with same multi-LED light engine, viewing booth coloured objects transported between Germany China. Observer significantly influenced by correlated temperature (2700 K–6500 K), object scene (red, blue or mixed), cultural background (Chinese origin, living in China) gender (men, women). results can...
A family of zinc β-pyridylenolates with varying α,β-substituents has been synthesized. direct reaction β-pyridyl ketone ligands ZnEt2 in toluene afforded dimeric [LZnEt]2 (L = (2-C5H4N)-C(R1)[double bond, length as m-dash]C(R2)-O-). X-ray structural data revealed that all the complexes exist μ-O-bridged dimers solid state, although they adopt a different geometry. Each is highly active catalyst for ring-opening polymerization (ROP) ε-caprolactone (ε-CL) and racemic lactide (rac-LA),...

Using two well-defined empirical parameters, we numerically investigate the details of disorder-induced topological state transition (TST) in photonic Chern insulators composed two-dimensional magnetic crystals (MPCs). The TST undergoes a gradual process, accompanied with some interesting phenomena as disorder rod positions MPCs increases gradually. This kind is determined by competition among topologically protected edge state, wave localizations and bulk states system. More interestingly,...
Temperature, current-direction, and film-thickness dependent anisotropic magnetoresistance measurements were performed on single-crystalline face-centered-cubic nickel films. An additional four-fold symmetry was confirmed besides the typical two-fold term even at room temperature. The angular-dependent longitudinal resistivity resolves into a term, which varies as function of current direction, is isotropically independent direction. experimental results are interpreted well using an...

The magnetoresistance (MR) of the single-crystalline Co/Pt(111) bilayers was studied systematically as a function Co or Pt thickness at room temperature. For dCo < 6 nm, resistances with in-plane magnetization M parallel (R∥) and transverse (R⊥) to current perpendicular normal (RP) film show unconventional behavior RP>R∥>R⊥. This MR can be attributed combination effect spin Hall RP≈R∥>R⊥ geometrical size effect. In addition, angular dependent (111)-oriented Co/Pt...
