A Skyrmion crystal typically arises from helical spin structures induced by the Dzyaloshinskii-Moriya interaction. Experimentally its physical exploration has been impeded because it is a rarity and found only within narrow temperature magnetic field range. We present method for assembly of two-dimensional based upon combination perpendicularly magnetized film nanopatterned arrays vortices that are geometrically confined nanodisks. The practical feasibility validated micromagnetic...
We present a method to quantify the spin Hall angle (SHA) with pumping and microwave photoresistance measurements. With this we separate inverse effect (ISHE) from other unwanted effects for permalloy/Pt bilayers using out-of-plane excitation. Through measurements, in- precessing angles of magnetization are determined enabled exact determination injected pure current. This is demonstrated an almost perfect Lorentz line shape obtained ISHE signal frequency independent SHA value as predicted...
Metal-free g-C3N4 is a promising candidate for the next-generation visible light-responsive photocatalyst; however, high recombination probability of photogenerated charge carriers on limits its photocatalytic activity. To further increase intrinsic activity g-C3N4, here, perylene tetracarboxylic diimide–g-C3N4 (PDI/GCN) heterojunctions are prepared by one-step imidization reaction between dianhydride (PTCDA) and in aqueous solution. By combination various testing results, it confirmed that...
Studies have demonstrated that curcumin (CUR) exerts its tumor suppressor function in a variety of human cancers including head and neck squamous cell carcinoma (HNSCC). However, the exact underlying molecular mechanisms remain obscure. Here, we aim to test whether CUR affects ATM/Chk2/p53 signaling pathway, leading induction cycle arrest, inhibition angiogenesis HNSCC vitro vivo. To this end, conducted multiple methods such as MTT assay, Invasion Flow cytometry, Western blotting, RT-PCR,...
Abstract SIRT1 is one of seven mammalian homologs Sir2 that catalyzes NAD + -dependent protein deacetylation. The aim the present study to explore effect small molecule activator on anticancer activity and underlying mechanism. We examined a novel oral agent, curcumin, which principal active ingredient traditional Chinese herb Curcuma Longa. Treatment FaDu Cal27 cells with curcumin inhibited growth induced apoptosis. Mechanistic studies showed associated decrease in migration HNSCC...
We study the transmission properties of light through symmetric Fibonacci-class $[\mathrm{SFC}(n)]$ quasiperiodic dielectric multilayers, which possess a mirror symmetry. For normal incidence light, many perfect peaks (the coefficients are unity) numerically obtained. The coefficient exhibits two-cycle feature in family $\mathrm{SFC}(n)$ with an odd n, while three-cycle another even n. scaling factors $f(n),$ give description self-similar behaviors spectra, analytical Let...
Green manure intercropping is an agronomic management practice that effectively increases soil nutrients in understory and reduces weed population. However, the influence of different green manures on properties bacterial community litchi orchards tropical regions China remains largely unknown. Here, we examined effect three leguminous crops Hainan Province. No was used as control. Different increased contents nutrients. For example, Desmodium ovalifolium total nitrogen content by 7.93%;...
The magnetic ground state of cobalt perovskite ${\mathrm{SrCoO}}_{3}$ is under much debate at present due to its complex properties. To shed further light on this issue we have studied various structures enlarged double cells. calculation carried out self-consistently within the unrestricted Hartree-Fock approximation and real-space recursion method. Our results show that mainly depends competition between crystal field strength $\mathrm{Dq}$ Hund's coupling $j$. For a fixed $j$, it can be...
A systematic study is carried out on the spin-filter (SF) tunneling magnetoresistance (TMR) occurring in a ferromagnetic metal/ferromagnetic insulator/ferromagnetic metal (FM/FI/FM) tunnel junction. The theoretical investigation gives unified and compact description SF TMR effects this structure, qualitatively explains relevant experiments area. Specifically, due to strong effect, can be separately controlled by extended Slonczewski's polarization factors, leading both barrier-height...
We performed micromagnetic simulations of the current-induced domain wall motion in permalloy nanowires with rectangular cross-section. In absence nonadiabatic spin-transfer term, a threshold current, Jc is required to drive moving continuously. find that proportional maximum cross product demagnetization field and magnetization orientation width. With varying both wire thickness width, minimum current order 106 A/cm2 obtained when equivalent calculated velocity ν equals adiabatic spin...

Furthermore, 10%CoCl2/PAL-B21 catalyst before after removal reaction characterized XRD,...
The photonic band structures of the two-dimensional square lattice air cylinders embedded in an ionic crystal are calculated using plane-wave method. dielectric function is taken as \ensuremath{\epsilon}(\ensuremath{\omega})=\ensuremath{\epsilon}(\ensuremath{\infty})(${\mathrm{\ensuremath{\omega}}}_{\mathrm{LO}}^{2}$-${\mathrm{\ensuremath{\omega}}}^{2}$)/(${\mathrm{\ensuremath{\omega}}}_{\mathrm{TO}}^{2}$-${\mathrm{\ensuremath{\omega}}}^{2}$), with \ensuremath{\epsilon}(\ensuremath{\infty}),...
We study the interaction of single Fe atoms on Cu(111) and Ag(111) substrates with low-temperature scanning tunneling microscopy kinetic Monte Carlo simulations. In Fe/Cu(111), a self-assembled hexagonal quasisuperlattice perturbation around 20% dimers/clusters is obtained. Fe/Ag(111), however, disorderlike structure found even though long-range interactions among are observed. combination simulations, possible mechanisms superstructure formation discussed. find that two parameters, i.e.,...
